     The present application for Patent claims the benefit of U.S. Provisional Patent Application No. 63/137,605 by PEZESHKI et al., entitled “TECHNIQUES FOR COMMON BEAM UPDATE RULES FOR SCHEDULED COMMUNICATIONS,” filed Jan. 14, 2021, assigned to the assignee hereof, and expressly incorporated by reference herein. 
    
    
     FIELD OF TECHNOLOGY 
     The following relates to wireless communications, including techniques for common beam update rules for scheduled communications. 
     BACKGROUND 
     Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE). Some wireless communications systems may enable the network (e.g., base stations) to update beams used for communications at a UE via downlink control information (DCI) messages. 
     SUMMARY 
     The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for common beam update rules for scheduled communications. Generally, aspects of the present disclosure provide techniques for configuring and/or signaling beam update configurations which define a timing for updating a common beam for communications with a user equipment (UE). For example, a UE may be configured with (e.g., via radio resource control (RRC) or other control signaling) one or more beam update configurations. Each beam update configuration may define a timing for updating a common beam for communications with the UE in relation to a downlink control information (DCI) message which updates a common beam at the UE and schedules a communication at the UE. Subsequently, upon receiving a DCI message which updates a common beam and schedules a communication at the UE, the UE may perform one or more beam switching procedures to update the common beam in accordance with the one or more beam update configurations. In some aspects, the DCI scheduling the transmission may indicate which beam update configuration is to be used. 
     A method for wireless communication at a UE is described. The method may include receiving control signaling indicating a beam update configuration that defines a timing for updating a common beam for communications with the UE in relation to a communication and in response to a DCI message that schedules the communication and indicates an update to the common beam, where the common beam is shared across a set of multiple channels, a set of multiple reference signals, or both, receiving, from a base station, the DCI message that schedules the communication and indicates the update to the common beam, and performing at least one beam switching procedure to update the common beam for communications with the UE based on receiving the DCI message and in accordance with the beam update configuration. 
     An apparatus for wireless communication at a UE is described. The apparatus may include a processor, memory in electronic communication with the processor, and instructions stored in the memory. The instructions may be executable by the processor to cause the apparatus to receive control signaling indicating a beam update configuration that defines a timing for updating a common beam for communications with the UE in relation to a communication and in response to a DCI message that schedules the communication and indicates an update to the common beam, where the common beam is shared across a set of multiple channels, a set of multiple reference signals, or both, receive, from a base station, the DCI message that schedules the communication and indicates the update to the common beam, and perform at least one beam switching procedure to update the common beam for communications with the UE based on receiving the DCI message and in accordance with the beam update configuration.

     DETAILED DESCRIPTION 
     Some wireless communications systems may enable a network (e.g., base stations) to update beams used for communications at a user equipment (UE) via downlink control information (DCI) messages. DCI messages may indicate transmission-configuration indicator (TCI) states which instruct a UE to update a beam used by the UE. In some conventional systems, a single DCI message was only capable of updating a single beam at a UE. In other wireless communications systems, a single DCI message may be configured to update multiple beams at a UE. In particular, a single DCI message may indicate a common TCI state which updates a common beam at a UE, where the common beam is shared across multiple channels, multiple reference signals, or both. For example, a DCI may include a common TCI state which updates a common beam at the UE that is used for an uplink channel and a downlink channel, multiple uplink channels, multiple downlink channels, or any combination thereof. 
     Enabling a single DCI message to update multiple beams (e.g., a common beam) at a UE may reduce control signaling overhead within a wireless communications system. However, current wireless communications systems do not provide signaling or other rules which instruct a UE as to when an update to a common beam should be implemented. As such, upon receiving a DCI message which schedules a transmission and indicates an update to a common beam, a UE may not know when the update to the common beam should be implemented. 
     Accordingly, aspects of the present disclosure provide techniques for configuring and/or signaling beam update configurations which define a timing for updating a common beam for communications with a UE. For example, a UE may be configured with (e.g., via radio resource control (RRC) or other control signaling) one or more beam update configurations. Each beam update configuration may define a timing for updating a common beam in relation to a DCI message which updates a common beam for communications with the UE and schedules a communication at the UE. Subsequently, upon receiving a DCI message which updates a common beam and schedules a communication (e.g., physical downlink shared channel (PDSCH) transmission, physical uplink control channel (PUCCH) transmission, physical uplink shared channel (PUSCH) transmission) at the UE, the UE may perform one or more beam switching procedures to update the common beam in accordance with the one or more beam update configurations. In some aspects, the DCI scheduling the transmission may indicate which beam update configuration is to be used. 
     According to a first beam update configuration, the UE may perform the beam switching procedures to update the common beam before or after the communication scheduled by the DCI based on a relative timing of the communication relative to a processing timeline (e.g., processing time threshold) at the UE. For example, if the communication is scheduled before the processing time threshold (e.g., before the UE has sufficient time to process the DCI and/or retune radio frequency components), the UE may update the common beam after the scheduled communication. Conversely, if the communication is scheduled after the processing time threshold, the UE may update the common beam prior to the scheduled communication, and may perform the scheduled communication using the updated common beam. According to a second beam update configuration, the UE may update the common beam after the scheduled communication, regardless of whether the processing time threshold of the UE is satisfied. A UE may be configured with any quantity of beam update configurations which define different timings for implementing updates to common beams. 
     By providing signaling and other configurations which indicate when a UE should implement updates to common beams, the techniques described herein may enable the network to update multiple beams (e.g., a common beam) at UEs using a single DCI message. In this regard, techniques described herein may thereby reduce control signaling overhead and improve resource utilization in the wireless communications system. Moreover, by providing beam update configurations which define timings for implementing updates to common beams, techniques described herein may improve the speed and efficiency with which beams may be updated at a UE, thereby improving the efficiency of wireless communications within the wireless communications system. 
     Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described in the context of example beam update configurations and an example process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for common beam update rules for scheduled communications. 
       FIG. 1  illustrates an example of a wireless communications system  100  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. The wireless communications system  100  may include one or more base stations  105 , one or more UEs  115 , and a core network  130 . In some examples, the wireless communications system  100  may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system  100  may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof. 
     The base stations  105  may be dispersed throughout a geographic area to form the wireless communications system  100  and may be devices in different forms or having different capabilities. The base stations  105  and the UEs  115  may wirelessly communicate via one or more communication links  125 . Each base station  105  may provide a coverage area  110  over which the UEs  115  and the base station  105  may establish one or more communication links  125 . The coverage area  110  may be an example of a geographic area over which a base station  105  and a UE  115  may support the communication of signals according to one or more radio access technologies. 
     The UEs  115  may be dispersed throughout a coverage area  110  of the wireless communications system  100 , and each UE  115  may be stationary, or mobile, or both at different times. The UEs  115  may be devices in different forms or having different capabilities. Some example UEs  115  are illustrated in  FIG. 1 . The UEs  115  described herein may be able to communicate with various types of devices, such as other UEs  115 , the base stations  105 , or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in  FIG. 1 . 
     The base stations  105  may communicate with the core network  130 , or with one another, or both. For example, the base stations  105  may interface with the core network  130  through one or more backhaul links  120  (e.g., via an S1, N2, N3, or other interface). The base stations  105  may communicate with one another over the backhaul links  120  (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations  105 ), or indirectly (e.g., via core network  130 ), or both. In some examples, the backhaul links  120  may be or include one or more wireless links. 
     One or more of the base stations  105  described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology. 
     A UE  115  may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE  115  may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE  115  may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples. 
     The UEs  115  described herein may be able to communicate with various types of devices, such as other UEs  115  that may sometimes act as relays as well as the base stations  105  and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in  FIG. 1 . 
     The UEs  115  and the base stations  105  may wirelessly communicate with one another via one or more communication links  125  over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links  125 . For example, a carrier used for a communication link  125  may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system  100  may support communication with a UE  115  using carrier aggregation or multi-carrier operation. A UE  115  may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. 
     In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be positioned according to a channel raster for discovery by the UEs  115 . A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs  115  via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different radio access technology). 
     The communication links  125  shown in the wireless communications system  100  may include uplink transmissions from a UE  115  to a base station  105 , or downlink transmissions from a base station  105  to a UE  115 . Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode). 
     A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system  100 . For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communications system  100  (e.g., the base stations  105 , the UEs  115 , or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system  100  may include base stations  105  or UEs  115  that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE  115  may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth. 
     Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements that a UE  115  receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE  115 . A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE  115 . 
     One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE  115  may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE  115  may be restricted to one or more active BWPs. 
     The time intervals for the base stations  105  or the UEs  115  may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T s =1/(Δf max ·N f ) seconds, where Δf max  may represent the maximum supported subcarrier spacing, and N f  may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023). 
     Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems  100 , a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation. 
     A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system  100  and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system  100  may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)). 
     Physical channels may be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs  115 . For example, one or more of the UEs  115  may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs  115  and UE-specific search space sets for sending control information to a specific UE  115 . 
     In some examples, a base station  105  may be movable and therefore provide communication coverage for a moving geographic coverage area  110 . In some examples, different geographic coverage areas  110  associated with different technologies may overlap, but the different geographic coverage areas  110  may be supported by the same base station  105 . In other examples, the overlapping geographic coverage areas  110  associated with different technologies may be supported by different base stations  105 . The wireless communications system  100  may include, for example, a heterogeneous network in which different types of the base stations  105  provide coverage for various geographic coverage areas  110  using the same or different radio access technologies. 
     The wireless communications system  100  may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system  100  may be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. The UEs  115  may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communication or group communication and may be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission critical functions may include prioritization of services, and mission critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency may be used interchangeably herein. 
     In some examples, a UE  115  may also be able to communicate directly with other UEs  115  over a device-to-device (D2D) communication link  135  (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs  115  utilizing D2D communications may be within the geographic coverage area  110  of a base station  105 . Other UEs  115  in such a group may be outside the geographic coverage area  110  of a base station  105  or be otherwise unable to receive transmissions from a base station  105 . In some examples, groups of the UEs  115  communicating via D2D communications may utilize a one-to-many (1:M) system in which each UE  115  transmits to every other UE  115  in the group. In some examples, a base station  105  facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs  115  without the involvement of a base station  105 . 
     The core network  130  may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network  130  may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs  115  served by the base stations  105  associated with the core network  130 . User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services  150  for one or more network operators. The IP services  150  may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service. 
     Some of the network devices, such as a base station  105 , may include subcomponents such as an access network entity  140 , which may be an example of an access node controller (ANC). Each access network entity  140  may communicate with the UEs  115  through one or more other access network transmission entities  145 , which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs). Each access network transmission entity  145  may include one or more antenna panels. In some configurations, various functions of each access network entity  140  or base station  105  may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station  105 ). 
     The wireless communications system  100  may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs  115  located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz. 
     The wireless communications system  100  may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system  100  may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations  105  and the UEs  115  may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples. 
     A base station  105  or a UE  115  may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station  105  or a UE  115  may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station  105  may be located in diverse geographic locations. A base station  105  may have an antenna array with a number of rows and columns of antenna ports that the base station  105  may use to support beamforming of communications with a UE  115 . Likewise, a UE  115  may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port. 
     The base stations  105  or the UEs  115  may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices. 
     The wireless communications system  100  may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE  115  and a base station  105  or a core network  130  supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels. 
     The UEs  115  and the base stations  105  may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link  125 . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval. 
     Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station  105 , a UE  115 ) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation). 
     A base station  105  or a UE  115  may use beam sweeping techniques as part of beam forming operations. For example, a base station  105  may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE  115 . Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station  105  multiple times in different directions. For example, the base station  105  may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station  105 , or by a receiving device, such as a UE  115 ) a beam direction for later transmission or reception by the base station  105 . 
     Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station  105  in a single beam direction (e.g., a direction associated with the receiving device, such as a UE  115 ). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE  115  may receive one or more of the signals transmitted by the base station  105  in different directions and may report to the base station  105  an indication of the signal that the UE  115  received with a highest signal quality or an otherwise acceptable signal quality. 
     In some examples, transmissions by a device (e.g., by a base station  105  or a UE  115 ) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station  105  to a UE  115 ). The UE  115  may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station  105  may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. The UE  115  may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted in one or more directions by a base station  105 , a UE  115  may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE  115 ) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device). 
     A receiving device (e.g., a UE  115 ) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station  105 , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions). 
     According to some implementations, downlink beamforming at a base station  105  may be performed such that it is transparent to a UE  115 , and vice versa. That is, when performing downlink beamforming at a base station  105 - b , a UE  115  does not need to know what beam is used at the base station  105 . In cases where the wireless communications system  100  supports NR, the wireless communications system  100  may also support signaling for beam indications. In practice, a base station  105  may inform a UE  115  that a respective PDSCH and/or physical downlink control channel (PDCCH) transmission uses the same transmission beam as a configured reference signal (e.g., CSI-RS, synchronization signal block). Moreover, beam indications may be used to inform a UE  115  that a respective PDSCH and/or PDCCH is transmitted using the same spatial filter as the configured reference signal. 
     As noted previously herein, beam indications may be based on configurations and signaling TCI states. Each TCI state may include information associated with one or more beams, including information regarding reference signals (e.g., CSI-RS, synchronization signal block), quasi co-location (QCL) configurations, spatial filters, and the like. In this regard, associating transmissions (e.g., reference signals, PDCCH transmissions, PDSCH transmissions) with a given TCI state may indicate, to other wireless devices, that the respective transmission was performed using a spatial filter associated with the TCI state. 
     In some cases, a wireless device (e.g., UE  115 ) may be configured with up to sixty-four candidate TCI states. RRC signaling may be used to assign candidate TCI states for each configured CORESET for PDCCH transmissions. Subsequently, after configuring candidate TCI states via RRC signaling, MAC signaling may be used to dynamically indicate a specific TCI state, within each CORESET-configured subset, which is to be activated. As such, once a receiving device (e.g., UE  1150 ) has determined a suitable receiver-side beam direction for reception of the reference signals, the receiving device may be configured to use the same beam (e.g., same beam direction) for other transmissions, such as PDCCH transmissions. 
     In the context of PDSCH transmissions, there are two alternatives for indicating beam indicators. The indication of beam indicators for PDSCH transmissions may depend on the scheduling offset of the respective PDSCH transmission (e.g., scheduling offset of the PDSCH transmission relative to the corresponding PDCCH transmission scheduling the PDSCH transmission). If this scheduling offset is larger than N symbols, the DCI message scheduling the PDSCH transmission may explicitly indicate the TCI state for the PDSCH transmission. In such cases, the UE  115  may be pre-configured (e.g., via RRC signaling) with up to eight TCI states from a set of candidate TCI states, and the DCI message may include an indication (e.g., three-bit indicator) of the active TCI state from the set of TCI states which is to be activated for the PDSCH transmission. Comparatively, ff the scheduling offset of a PDSCH transmission is less than or equal to N symbols, a UE  115  may be configured to determine that the PDSCH transmission is QCL with the corresponding PDCCH transmission scheduling the PDSCH transmission. In other words, the UE  115  may be configured to determine that the TCI state indicated via MAC signaling is also valid for the PDSCH transmission. The varying techniques for determining TCI states relative to the scheduling offset may be based on a processing time at the UE  115  which is required for decoding the TCI information and performing beam switching procedures in order to receive the PDSCH transmission. 
     In some aspects, the UEs  115  and the base stations  105  of the wireless communications system  100  may support techniques for configuring and/or signaling beam update configurations which define a timing for updating a common beam for communications with a UE  115 . In particular, techniques described herein may define beam update configurations and signaling for beam update configurations which may improve the implementation of common beam updates at a UE  115 . 
     For example, a UE  115  of the wireless communications system  100  may be configured with (e.g., via RRC or other control signaling) one or more beam update configurations. Each beam update configuration may define a timing for updating a common beam for communications with the UE  115  in relation to a DCI message which updates a common beam for communications with the UE  115  and schedules a communication with the UE  115 . As noted previously herein, a common beam may be shared across multiple channels, multiple reference signals, or both. For example, a common beam may be used for an uplink channel and a downlink channel, multiple uplink channels, multiple downlink channels, or any combination thereof. 
     Subsequently, the UE  115  may receive a DCI message which updates a common beam and schedules a communication (e.g., PDSCH transmission, PUCCH transmission, PUSCH transmission) at the UE  115 . Upon receiving the DCI message, the UE  115  may perform one or more beam switching procedures to update the common beam in accordance with the one or more beam update configurations. In some aspects, the DCI scheduling the communication may indicate which beam update configuration is to be used. 
     According to a first beam update configuration, the UE  115  may perform the beam switching procedures to update the common beam before or after the communication scheduled by the DCI message based on a relative timing of the communication relative to a processing timeline (e.g., processing time threshold) at the UE  115 . For example, if the communication is scheduled before the processing time threshold (e.g., before the UE  115  has sufficient time to process the DCI message and/or retune radio frequency components), the UE  115  may update the common beam after the scheduled communication. Conversely, if the communication is scheduled after the processing time threshold, the UE  115  may update the common beam prior to the scheduled communication, and may perform the scheduled communication using the updated common beam. According to a second beam update configuration, the UE  115  may update the common beam after the scheduled communication, regardless of whether the processing time threshold of the UE  115  is satisfied. In some aspects, each UE  115  of the wireless communications system  100  may be configured with any quantity of beam update configurations which define different timings for implementing updates to common beams. 
     The techniques described herein may provide signaling and other configurations which indicate when a UE  115  should implement updates to common beams. As such, the techniques described herein may enable the network to update multiple beams (e.g., a common beam) at UEs  115  using a single DCI message. In this regard, techniques described herein may thereby reduce control signaling overhead and improve resource utilization in the wireless communications system. Moreover, by providing beam update configurations which define timings for implementing updates to common beams, techniques described herein may improve the speed and efficiency with which beams may be updated at a UE  115 , thereby improving the efficiency of wireless communications within the wireless communications system  100 . 
       FIG. 2  illustrates an example of a wireless communications system  200  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. In some examples, wireless communications system  200  may implement, or be implemented by, aspects of wireless communications system  100 . The wireless communications system  200  may include a UE  115 - a  and a base station  105 - a , which may be examples of UEs  115  and base stations  105 , as described with reference to  FIG. 1 . 
     In some aspects, the UE  115 - a  and the base station  105 - a  may communicate with one another via a communication link  205 . In some aspects, the communication link  205  may include an example of an access link (e.g., Uu link). The communication link  205  may include a bi-directional link that can include both uplink and downlink communication. For example, the UE  115 - a  may transmit uplink transmissions, such as uplink control signals or uplink data signals, to the base station  105 - a  using the communication link  205 , and the base station  105 - a  may transmit downlink transmissions, such as downlink control signals or downlink data signals, to the UE  115 - a  using the communication link  205 . In some aspects, the wireless communications system  200  may support wireless communications with wireless devices (e.g., UE  115 - a ) via one or more serving cells of the wireless communications system  200 . Each serving cell may be supported by one or more base stations  105  of the wireless communications system  200 . 
     In some aspects, the UE  115 - a  and the base station  105 - a  may communicate with one another using one or more beams, one or more carriers, one or more communications links, or any combination thereof. In some aspects, the UE  115 - a  may communicate with the base station  105 - a  via one or more common beams  210 . In some aspects, each common beam  210  may be associated with (e.g., used for) multiple channels, multiple reference signals, or both. For example, the UE  115 - a  may be configured to use the common beam  210 - a  for a downlink channel of the communication link  205  and an uplink channel of the communication link  205 . By way of another example, the UE  115 - a  may be configured to use the common beam  210 - a  for multiple downlink channels of the communication link  205 , multiple uplink channels of the communication link  205 , or both. Furthermore, the UE  115 - a  may be configured to use the common beam  210 - a  for a first set of reference signals and a second set of reference signals. 
     In some aspects, the base station  105 - a , the UE  115 - a , or both, may perform directional beamforming for performing transmissions via the communication link  205 . The UE  115 - a  may be configured to perform beam switching procedures to transition from one beam to another. For example, the UE  115 - a  may be configured to communicate using the first common beam  210 - a , and may perform a beam switching procedure to transition from the first common beam  210 - a  to the second common beam  210 - b  in order to communicate according to the second common beam  210 - b . Beam switching procedures may involve processing at the UE  115 - a , retuning of radio frequency components, or both. In some cases, different beams (e.g., common beams  210 ) may be configured according to different parameters (e.g., different TCI states, transmission powers). 
     As noted previously herein, in some wireless communications systems, a single DCI message may only be capable of updating a single beam at a UE  115 . In other wireless communications systems, a single DCI message may be configured to update multiple beams at a UE  115 . In particular, a single DCI message may indicate a common TCI state which updates a common beam  210  at a UE  115 . Enabling a single DCI message to update multiple beams (e.g., a common beam  210 ) at a UE  115  may reduce control signaling overhead within a wireless communications system. However, current wireless communications systems do not provide signaling or other rules which instruct a UE  115  as to when an update to a common beam should be implemented. As such, upon receiving a DCI message which schedules a transmission and indicates an update to a common beam, a UE  115  may not know when the update to the common beam should be implemented. 
     Accordingly, the wireless communications system  200  may support techniques for configuring and/or signaling beam update configurations which define a timing for updating common beams  210  at the UE  115 - a . In particular, techniques described herein may define beam update configurations and signaling for beam update configurations which may improve the implementation of updates to a common beam  210  at the UE  115 - a.    
     For example, the UE  115 - a  may receive an RRC message  215  from the base station  105 - a . In some aspects, the RRC message  215  may indicate one or more beam update configurations for updating common beams  210  configured for wireless communications at and/or with the UE  115 - a . In this regard, the RRC message  215  may configure the UE  115 - a  with a set of beam update configurations which may be used to update common beams  210 . Each of the beam update configurations may define a timing for updating a common beam  210  for communications at or with the UE  115 - a . In particular, each beam update configuration may define a timing for updating a common beam  210  at the UE  115 - a  in relation to a communication  230  and in response to a DCI message  225  that schedules the communication  230  and indicates an update to the common beam  210 . As noted previously herein, a common beam  210  at the UE  115 - a  which may be updated according to one or more of the beam update configurations may be shared across a set of channels (e.g., downlink and uplink channel, multiple downlink channels, multiple uplink channels), a set of reference signals, or both. Thus, common beams  210  may include downlink beams used to receive downlink transmissions, uplink beams used to transmit uplink transmissions, or both. Various beam update configurations will be described in further detail herein with respect to  FIGS. 3 and 4 . 
     In some aspects, UE  115 - a  may transmit an indication of a processing time threshold  220  (e.g., processing timeline) associated with the UE  115 - a . The UE  115 - a  may transmit the indication of the processing time threshold  220  based on receiving the RRC message  215 . In some aspects, the processing time threshold  220  may be associated with a processing timeline for processing communications at the UE  115 - a , performing beam switching procedures, or both. For example, the processing time threshold  220  at the UE  115 - a  may be based on a first time duration associated with downlink control channel processing (e.g., PDCCH processing) at the UE  115 - a , a second time duration associated with retuning radio frequency components at the UE  115 - a , or both. For instance, the processing time threshold  220  may be based on a duration of time required for the UE  115 - a  to decode DCI messages  225 . In this regard, the processing time threshold  220  may be associated with a duration of time between a first time when the UE  115 - a  receives a grant (e.g., DCI message  225 ), and a second time at which the UE  115 - a  is capable of acting in accordance with the grant. Thus, the processing time threshold  220  may be defined by a quantity of slots, a quantity of symbols, and the like. In some cases, processing time threshold  220  may include a K0 value, a K1 value, a K2 value, or any combination thereof. 
     The UE  115 - a  may receive a DCI message  225  from the base station  105 - a . In some aspects, the UE  115 - a  may receive the DCI message  225  using the first common beam  210 - b . The UE  115 - a  may receive (and the base station  105 - a  may transmit) the DCI message  225  based on transmitting/receiving the RRC message  215 , transmitting/receiving the processing time threshold  220 , or both. The DCI message  225  may be transmitted via Layer 1 (L1) signaling. Additionally, the DCI message  225  may include a unicast transmission, and may include any number of formats for DCI messages (e.g., DCI 1_1, DCI 1_2). 
     In some aspects, the DCI message  225  may indicate an update to a common beam  210  which is to be performed at the UE  115 - a . In this regard, the DCI message  225  may indicate that the UE  115 - a  is to perform a beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b . For example, the DCI message  225  may indicate a common TCI state for updating the first common beam  210 - a  for communications with the UE  115 - a . A TCI state may include at least one source reference signal to provide a reference for the UE  115 - a  to determine a QCL configuration and/or spatial filter for updating the common beam  210 - a . The common beam  210  which is to be updated in accordance with the DCI message  225  may be shared across multiple channels, multiple reference signals, or both. 
     Moreover, the common beam  210  may be associated with transmissions carried out via a single TRP of the UE  115 - a  and/or base station  105 - a , multiple TRPs of the UE  115 - a  and/or base station  105 - a , a single CORESET, multiple CORESETs, or any combination thereof. For example, the common beam  210  may be shared across a downlink channel and an uplink channel, multiple downlink channels, multiple uplink channels, multiple reference signals, or any combination thereof. 
     For instance, the DCI message  225  may indicate a joint uplink/downlink common TCI state configured to update a common beam  210  shared across a downlink channel and an uplink channel, shared across two reference signals, or both. Additionally, the DCI message  225  may indicate a separate downlink-common TCI state configured to update a common beam  210  shared across two downlink channels, shared across two reference signals, or both. For example, the common beam  210  may be shared across a PDSCH channel and a PDCCH channel. Similarly, the DCI message  225  may indicate a separate uplink-common TCI state configured to update a common beam  210  shared across two uplink channels, shared across two reference signals, or both. 
     In some aspects, source reference signals associated with downlink-common TCI states may provide QCL information for reception of downlink transmissions (e.g., PDSCH transmissions) at the UE  115 - a , which may be applied for downlink reception on all or a subset of CORESETs within a component carrier. Similarly, source reference signals associated with uplink-common TCI states may provide a reference for determining common uplink transmission spatial filters for grants (e.g., dynamic grants, configured grants) based on uplink transmissions (e.g., PUSCH transmissions) at the UE  115 - a , which may be applied for uplink transmission on all or a subset of PUCCH resources within a component carrier. In some cases, uplink transmission spatial filters associated with uplink-common TCI states may also apply to all or a subset of sounding reference signal (SRS) resources in a resource set which are configured for antenna switching and/or uplink transmissions (e.g., codebook-based uplink transmissions, non-codebook-based uplink transmissions). In some cases, MAC-control element (MAC-CE) messages may additionally or alternatively be used to activate one or more TCI states. 
     Additionally, or alternatively, the DCI message  225  may schedule a communication  230  (e.g., PDSCH transmission, PUCCH transmission, PUSCH transmission) between the base station  105 - a  and the UE  115 - a . In some aspects, the timing of the communication  230  scheduled by the DCI message  225  may be based on the processing time threshold  220  at the UE  115 - a . In particular, the base station  105 - a  may schedule the communication  230  via the DCI message  225  in accordance with the processing time threshold  220  based on which common beam  210  should be used to perform the communication  230 . In this regard, the base station  105 - a  may schedule the communication  230  via the DCI message  225  in order to ensure that the UE  115 - a  does (or does not) have sufficient time to perform the update to the common beam  210  prior to the communication  230 . For instance, the base station  105 - a  may schedule the communication  230  via the DCI message  225  prior to the processing time threshold  220  so that the UE  115 - a  does not have sufficient time to perform the update to the common beam  210  prior to the communication  230 . As such, the base station  105 - a  may be able to control or influence which common beam  210  (e.g., first common beam  210 - a , second common beam  210 - b ) is used at the UE  115 - a  to perform the scheduled communication  230  based on a relative timing of the communication  230  with respect to the DCI message  225 . 
     In some cases, the UE  115 - a  may transmit one or more feedback messages to the base station  105 - a  based on (e.g., in response to) the DCI message  225 . For example, the UE  115 - a  may transmit an acknowledgement (ACK) message in cases where the UE  115 - a  successfully receives and/or decodes the DCI message  225 . Conversely, the UE  115 - a  may transmit a negative acknowledgement (NACK) message in cases where the UE  115 - a  does not successfully receive and/or decode the DCI message  225 . In such cases, the NACK may serve as a request for the base station  105 - a  to re-transmit the DCI message  225 . 
     The UE  115 - a , the base station  105 - a , or both, may identify which beam update configuration is to be used to implement the update to the common beam  210 . The UE  115 - a  and/or the base station  105 - a  may determine which beam update configuration is to be used based on transmitting/receiving the RRC message  215 , transmitting/receiving the processing time threshold  220 , transmitting/receiving the DCI message  225 , transmitting/receiving additional or alternative control signaling, or any combination thereof. 
     In some cases, the DCI message  225  may dynamically indicate a beam update configuration which is to be used to update the common beam  210  indicated by the DCI message  225 . For example, in some cases, the beam update configuration which is to be used for implementing the update to the common beam  210  may be indicated dynamically via the DCI message  225  (e.g., without any pre-configuration at the UE  115 - a  or signaling from the base station  105 - a ). In such cases, the DCI message  225  may include an indication of the beam update configuration which is to be used. 
     In other cases, the UE  115 - b  may be pre-configured (e.g., via the RRC message  215 ) with a beam update configuration which is to be used. In additional or alternative cases, the beam update configuration which is to be used may be signaled via a combination of the RRC message  215  and the DCI message  225 . For example, the RRC message  215  may configure the UE  115 - a  with a set of beam update configurations which may be used. Subsequently, the DCI message  225  may indicate which beam update configuration of the set of beam update configurations is to be used. 
     The relative timing for implementing the update to the common beam  210  may change depending on the beam update configuration which is to be used. For example, according to one beam update configuration, the UE  115 - a  may be configured to update the common beam  210  after performance of the communication  230  scheduled by the DCI message  225 . According to this beam update configuration, the UE  115 - a  may always update the common beam  210  after the scheduled communication  230  regardless of whether the processing time threshold  220  is satisfied at the UE  115 - b . Accordingly, according to this beam update configuration, the UE  115 - a  may perform the communication  230  scheduled by the DCI message  225 , and may perform a beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b  (e.g., updated common beam  210 - b ) after performance of the communication  230 . As such, the UE  115 - a  may perform additional communications in accordance with the updated common beam  210 - b . Details of this beam update configuration will be described in further detail with respect to  FIG. 4 . 
     According to another beam update configuration, the relative timing of the update to the common beam  210  may be based on the processing time threshold  220 . In particular, the timing for the update to the common beam  210  may be based on a comparison of the processing time threshold  220  and a time interval between the DCI message  225  and the scheduled communication  230 . 
     According to this beam update configuration, the UE  115 - a , the base station  105 - a , or both, may identify a time interval between transmission/reception of the DCI message  225  and the scheduled communication  230 . For example, the UE  115 - a  may identify a time interval between reception of the DCI message  225  and a time at which the scheduled communication  230  is to be performed (e.g., a time at which the scheduled communication  230  is to be transmitted or received). As such, the UE  115 - a  and/or the base station  105 - a  may identify the time interval based on transmitting/receiving the RRC message  215 , transmitting/receiving the processing time threshold  220 , transmitting/receiving the DCI message  225 , identifying the beam update configuration, identifying a time at which the communication  230  scheduled by the DCI message  225  is to be performed, or any combination thereof. The time interval may include a quantity of slots, a quantity of symbols, and the like. 
     Subsequently, the UE  115 - a , the base station  105 - a , or both, may compare the time interval with the processing timeline (e.g., processing threshold) at the UE  115 - a . In some aspects, the UE  115 - a  and/or the base station may perform the comparison based on transmitting/receiving the RRC message  215 , transmitting/receiving the processing time threshold  220 , transmitting/receiving the DCI message  225 , identifying the beam update configuration, identifying a time at which the communication  230  scheduled by the DCI message  225  is to be performed, identifying the time interval, or any combination thereof. 
     As noted previously herein, the time interval may define a time duration between the DCI message  225  and the communication  230  scheduled by the DCI message  225 . Similarly, the time interval may define a time duration between the DCI message  225  and a time at which the UE  115 - a  is capable of acting in accordance with the DCI message  225  (e.g., performing the communication  230  scheduled by the DCI message  225 ). As such, in some cases, both the time interval and the processing time threshold  220  may be based on a time at which the DCI message  225  was transmitted/received. However, the time duration, the processing time threshold  220 , and/or other time durations (e.g., minimum beam indication delay) may be measured and/or initiated relative to additional or alternative points in time, such as a time at which DCI message  225  was acknowledged (e.g., time of ACK/NACK responsive to DCI message  225 ). Minimum beam indication delays may exhibit one or more values (e.g., 0.5 ms, 2 ms, 3 ms). 
     According to some beam update configurations, the relative timing of the update to the common beam  210  may be based on the comparison of the time interval (T Int ) and the processing time threshold  220  (PT Thresh ). In particular, the relative timing of the update to the common beam  210  may be based on whether or not the time interval satisfies the processing time threshold  220 . In some aspects, the time interval may satisfy the processing time threshold  220  if the time interval is greater than or equal to the processing threshold (e.g., processing timeline satisfied if T Int ≥PT Thresh ). In this regard, the communication  230  scheduled by the DCI message  225  may be scheduled after an end of the processing time threshold  220 , thereby satisfying the processing time threshold  220  and providing the UE  115 - a  with sufficient time to process the DCI message  225  and perform the beam switching procedure (e.g., radio frequency component retuning). 
     Conversely, the time interval may fail to satisfy the processing time threshold  220  if the time interval is less than the processing time threshold  220  (e.g., processing timeline not satisfied if T Int &lt;PT Thresh ). In this regard, the communication  230  scheduled by the DCI message  225  may be scheduled before an end of the processing time threshold  220 , thereby failing to satisfy the processing time threshold  220  due to the fact that the UE  115 - a  may not have sufficient time to process the DCI message  225  and perform the beam switching procedure (e.g., radio frequency component retuning). 
     Accordingly, in some aspects, the UE  115 - a  may be configured to perform at least one beam switching procedure after performance of the communication  230  scheduled by the DCI message  225  if the time interval fails to satisfy the processing time threshold  220  (e.g., update common beam  210  after scheduled communication  230  if T Int &lt;PT Thresh ). Conversely, the UE  115 - a  may be configured to perform at least one beam switching procedure prior to performance of the communication  230  scheduled by the DCI message  225  if the time interval satisfies the processing time threshold  220  (e.g., update common beam  210  before scheduled communication  230  if T Int ≥PT Thresh ). 
     In some aspects, the UE  115 - a  may perform at least one beam switching procedure to update the common beam  210  (e.g., update the first common beam  210 - a  to the second/updated common beam  210 - b ). In some aspects, the UE  115 - a  may perform the at least one beam switching procedure based on the DCI message  225  and in accordance with the beam update configuration. In this regard, the UE  115 - a  may update the common beam  210  based on receiving the RRC message  215 , transmitting the processing time threshold  220 , receiving the DCI message  225 , identifying the beam update configuration, identifying the time interval, comparing the time interval and the processing time threshold  220 , or any combination thereof. For example, the UE  115 - a  may perform the at least one beam switching procedure based on (e.g., in accordance with) a common TCI state indicated in the DCI message  225 . 
     For example, according to some beam update configurations, the UE  115 - a  may perform the beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b  prior to performing the communication  230  scheduled by the DCI message  225  based on the comparison of the time interval and the processing time threshold  220 . In particular, according to some beam update configurations, the UE  115 - a  may perform the beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b  prior to performing the communication  230  scheduled by the DCI message  225  if the time interval satisfies the processing time threshold  220  (e.g., update common beam  210  before scheduled communication  230  if T Int ≥PT Thresh ). 
     Continuing with the example above, the UE  115 - a  may perform the communication  230  scheduled by the DCI message  225 . The communication  230  may include a PDSCH transmission, a PUCCH transmission, a PUSCH transmission, or any combination thereof. In some aspects, the UE  115 - a  may perform the communication  230  scheduled by the DCI message  225  based on performing the at least one beam switching procedure. In this regard, the UE  115 - a  may perform the communication  230  scheduled by the DCI message  225  using the updated common beam  210 - b . For example, in cases where the time interval satisfies the processing time threshold  220  (e.g., T Int ≥PT Thresh ), the UE  115 - a  may update the common beam  210 , and may perform the communication  230  using the updated common beam  210 - b.    
     For instance, in cases where the DCI message  225  schedules an uplink communication  230 - a , and the UE  115 - a  updates the first common beam  210 - a  to the second common beam  210 - b  prior to performing the uplink communication  230 - a , the UE  115 - a  may perform the uplink communication  230 - a  using the second common beam  210 - b . By way of another example, in cases where the DCI message  225  schedules a downlink communication  230 - b , and the UE  115 - a  updates the first common beam  210 - a  to the second common beam  210 - b  prior to performing the downlink communication  230 - b , the UE  115 - a  may perform the downlink communication  230 - b  using the second common beam  210 - b.    
     In additional or alternative cases, the UE  115 - a  may not perform the beam switching procedure prior to performing the communication  230 . For example, cases where the time interval fails to satisfy the processing time threshold  220  (e.g., T Int &lt;PT Thresh ), the UE  115 - a  may refrain from performing the beam switching procedure prior to performance of the scheduled communication  230 . In such cases, the UE  115 - a  may perform the communication  230  using the same common beam  210  (e.g., first common beam  210 - a ) which was used to receive the DCI message  225 . 
     Thus, in cases where the UE  115 - a  refrains from performing the beam switching procedure prior to performing the communication  230 , the UE  115 - a  may perform at least one beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b  after performance of the scheduled communication  230 . The UE  115 - a  may perform the at least one beam switching procedure based on the DCI message  225  and in accordance with the beam update configuration. In this regard, the UE  115 - a  may update the common beam  210  based on receiving the RRC message  215 , transmitting the processing time threshold  220 , receiving the DCI message  225 , identifying the beam update configuration, identifying the time interval, comparing the time interval and the processing time threshold  220 , performing the scheduled communication  230 , or any combination thereof. Moreover, the UE  115 - a  may perform the beam switching procedure after performance of the communication  230  based on refraining from performing the beam switching procedure prior to performance of the scheduled communication  230 . 
     For example, according to some beam update configurations, the UE  115 - a  may perform the beam switching procedure to update the first common beam  210 - a  to the second common beam  210 - b  after performing the communication  230  scheduled by the DCI message  225  based on the comparison of the time interval and the processing time threshold  220 . In particular, according to some beam update configurations, the UE  115 - a  may perform the beam switching procedure to update the common beam  210  after performing the communication  230  scheduled by the DCI message  225  if the time interval fails to satisfy the processing time threshold  220  (e.g., update common beam  210  after scheduled communication  230  if T Int &lt;PT Thresh ). By performing the beam switching procedure after performance of the communication  230 , the UE  115 - a  may be configured to perform the communication  230  with the same common beam  210  (e.g., first common beam  210 - a ) which was used to receive the DCI message  225 . 
     In some cases, the UE  115 - a  may perform additional communications (e.g., PDCCH transmissions, PDSCH transmissions, PUCCH transmissions, PUSCH transmissions) with the base station  105 - a . In some aspects, the UE  115 - a  may perform the additional communications with the base station  105 - a  based on performing the at least one beam switching procedure before and/or after the scheduled communication  230 . In this regard, the UE  115 - a  may perform the additional communications using the updated common beam  210 - b  which was generated based on the beam switching procedure(s). 
     The techniques described herein may provide signaling and other configurations which indicate when the UE  115 - a  should implement updates to common beams  210 . As such, the techniques described herein may enable the base station  105 - a  to update multiple beams (e.g., a common beam  210 ) at the UE  115 - a  using a single DCI message  225 . In this regard, techniques described herein may thereby reduce control signaling overhead and improve resource utilization in the wireless communications system. Moreover, by providing beam update configurations which define timings for implementing updates to common beams  210 , techniques described herein may improve the speed and efficiency with which beams may be updated at the UE  115 - a , thereby improving the efficiency of wireless communications within the wireless communications system. 
       FIG. 3  illustrates an example of a beam update configuration  300  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. In some examples, the beam update configuration  300  may implement, or be implemented by, aspects of wireless communications system  100 , wireless communications system  200 , or both. In some aspects, the beam update configuration  300  illustrates a first beam update configuration which may be signaled and/or configured at a UE  115  to specify a timing of implementing a common beam update at the UE  115 . 
     According to the beam update configuration  300 , the timing of an update to a common beam  310  for communications with a UE  115 - b  may be based on a comparison of a processing time threshold  325  associated with the UE  115 - b  and a time interval  330  between a DCI message  315  and a communication  320  scheduled by the DCI message  315 . In particular, the timing of the update to the common beam  310  may be dependent on whether or not the time interval  330  satisfies the processing time threshold  325 . 
     In some aspects, the time interval  330  may satisfy the processing time threshold  325  if the time interval  330  is greater than or equal to the processing time threshold  325  (e.g., processing timeline satisfied if T Int ≥PT Thresh ). Conversely, the time interval  330  may fail to satisfy the processing time threshold  325  if the time interval  330  is less than the processing time threshold  325  (e.g., processing timeline not satisfied if T Int &lt;PT Thresh ). The relative timing of an update to the common beam  310  based on whether or not the processing time threshold is satisfied is illustrated in timing schemes  305 - a  and  305 - b.    
     Referring to timing scheme  305 - a , a UE  115 - b  may receive a DCI message  315  from a base station  105  which schedules a communication  320  between the base station  105  and the UE  115 - b . The UE  115 - b  may receive the DCI message  315  via a first common beam  310 - a . In some aspects, the DCI message  315  may additionally indicate a common update to the common beam  310 - a  for communications at and/or with the UE  115 - a , where the common beam  310 - a  is shared across a set of channels, a set of reference signals, or both. Upon receiving the DCI message  315 , the UE  115 - b  may determine the beam update configuration (e.g., beam update configuration  300 ) which is to be used to implement the update to the common beam  310 - a . The beam update configuration  300  may be indicated to the UE  115 - b  via the DCI message  315 , via RRC signaling, via other control signaling, or any combination thereof. 
     In some aspects, and in accordance with the determined beam update configuration  300 , the UE  115 - b  may determine a time interval  330 - a  between reception of the DCI message  315  and the scheduled communication  320 . The UE  115 - b  may then compare the time interval  330 - a  to the processing time threshold  325  associated with the UE  115 - b . In this example, the UE  115 - b  may determine that the time interval  330 - a  fails to satisfy the processing time threshold  325  due to the fact that the time interval  330 - a  is less than the processing time threshold  325  (e.g., processing timeline not satisfied because T Int &lt;PT Thresh ). The time interval  330 - a  failing to satisfy the processing time threshold  325  may indicate that the UE  115 - b  does not have sufficient time to process the DCI message  315  and/or perform beam switching procedures (e.g., retune radio frequency components) prior to performance of the communication  320 . 
     Accordingly, as shown in the timing scheme  305 - a , the UE  115 - b  may perform the communication  320  scheduled by the DCI message  315 , and may perform one or more beam switching procedures to update the common beam  310 - a  after performance of the communication  320 . In this regard, the UE  115 - b  may perform the communication  320  using the first common beam  310 - a  which was used to receive the DCI message  315 , and may perform subsequent transmissions using the updated common beam  310 - b.    
     Comparatively, referring to timing scheme  305 - b , the UE  115 - b  may determine that a time interval  330 - b  satisfies the processing time threshold  325  due to the fact that the time interval  330 - b  is greater than (or equal to) the processing time threshold  325  (e.g., processing timeline satisfied because T Int ≥PT Thresh ). The time interval  330 - b  satisfying the processing time threshold  325  may indicate that the UE  115 - b  has sufficient time to process the DCI message  315  and/or perform beam switching procedures (e.g., retune radio frequency components) prior to performance of the communication  320 . 
     Accordingly, as shown in the timing scheme  305 - b , the UE  115 - b  may perform one or more beam switching procedures to update the common beam  310 - c  prior to performance of the communication  320 . In this regard, the UE  115 - b  may update the first common beam  310 - c  to the second common beam  310 - d  (e.g., updated common beam  310 - d ), and may perform the communication  320  using the updated common beam  310 - d.    
       FIG. 4  illustrates an example of a beam update configuration  400  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. In some examples, the beam update configuration  400  may implement, or be implemented by, aspects of wireless communications system  100 , wireless communications system  200 , or both. In some aspects, the beam update configuration  400  illustrates a second beam update configuration which may be signaled and/or configured at a UE  115 - c  to specify a timing of implementing a common beam update at the UE  115 - c.    
     According to the beam update configuration  400 , an update to a common beam  410  for communications at and/or with the UE  115 - c  may be performed after performance of a communication  420  scheduled by a DCI message  415 , regardless as to whether or not a processing time threshold (e.g., processing time threshold  325 ) at the UE  115 - c  is satisfied. In this regard, as compared to the beam update configuration  300  in which the timing of the update to the common beam  310  was based on the processing time threshold  325  and the time interval, the update to the common beam  410  according to the beam update configuration  400  may always be performed after the scheduled communication  420 . 
     For example, as shown in timing scheme  405 , a UE  115 - c  may receive a DCI message  415  from a base station  105  which schedules a communication  420  between the base station  105  and the UE  115 - c . The UE  115 - c  may receive the DCI message  415  via a first common beam  410 - a . In some aspects, the DCI message  415  may additionally indicate a common update to the common beam  410 - a  for communications with the UE  115 - c , where the common beam  410 - a  is shared across a set of channels, a set of reference signals, or both. Upon receiving the DCI message  415 , the UE  115 - c  may determine the beam update configuration (e.g., beam update configuration  400 ) which is to be used to implement the update to the common beam  410 - a . The beam update configuration  400  may be indicated to the UE  115 - c  via the DCI message  415 , via RRC signaling, via other control signaling, or any combination thereof. 
     In some aspects, and in accordance with the determined beam update configuration  400 , the UE  115 - c  may perform the communication  420  scheduled by the DCI message  415 , and may perform one or more beam switching procedures after performance of the communication  420  to update the first common beam  410 - a  to the second common beam  410 - b . In this regard, the UE  115 - c  may perform the communication  420  using the first common beam  410 - a  which was used to receive the DCI message  415 , and may perform subsequent transmissions using the updated common beam  410 - b.    
       FIG. 5  illustrates an example of a process flow  500  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. In some examples, process flow  500  may implement, or be implemented by, aspects of wireless communications system  100 , wireless communications system  200 , beam update configuration  300 , beam update configuration  400 , or any combination thereof. For example, the process flow  500  may illustrate a UE  115 - d  receiving control signaling indicating one or more beam update configurations, receiving a DCI message which indicates an update to a common beam, and implementing the update to the common beam in accordance with the beam update configuration, as described with reference to  FIGS. 1-4 , among other aspects. 
     In some aspects, the process flow  500  may include a UE  115 - d  and a base station  105 - b , which may include examples of UEs  115  and base stations  105  as described with reference to  FIGS. 1-4 . For example, the UE  115 - d  illustrated in  FIG. 5  may be an example of the UE  115 - a  illustrated in  FIG. 2 , and the base station  105 - b  illustrated in  FIG. 5  may be an example of the base station  105 - a  illustrated in  FIG. 2 . 
     In some examples, the operations illustrated in process flow  500  may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components), code (e.g., software or firmware) executed by a processor, or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added. 
     At  505 , the UE  115 - d  may receive an RRC message from the base station  105 - b . In some aspects, the RRC message may indicate one or more beam update configurations for updating common beams for communications at/with the UE  115 - d . In this regard, the RRC message may configure the UE  115 - d  with a set of beam update configurations which may be used to update common beams for communications with the UE  115 - d . Each of the beam update configurations may define a timing for updating a common beam. In particular, each beam update configuration may define a timing for updating a common beam for communications with the UE  115 - d  in relation to a transmission and in response to a DCI message that schedules the transmission and indicates an update to the common beam. As noted previously herein, a common beam at the UE  115 - d  which may be updated according to one or more of the beam update configurations may be shared across a set of channels (e.g., downlink and uplink channel, multiple downlink channels, multiple uplink channels), a set of reference signals, or both. 
     At  510 , the UE  115 - d  may transmit an indication of a processing time threshold (e.g., processing timeline) associated with the UE  115 - d . The UE  115 - d  may transmit the indication of the processing time threshold based on receiving the RRC message at  505 . In some aspects, the processing time threshold may be associated with a processing timeline for processing transmissions at the UE  115 - d , performing beam switching procedures, or both. For example, the processing time threshold at the UE  115 - d  may be based on a first time duration associated with downlink control channel processing (e.g., PDCCH processing) at the UE  115 - d , a second time duration associated with retuning radio frequency components at the UE  115 - d , or both. For instance, the processing time threshold may be based on a duration of time required for the UE  115 - d  to decode DCI messages. In this regard, the processing time threshold may be associated with a duration of time between a first time when the UE  115 - d  receives a grant (e.g., DCI message), and a second time at which the UE  115 - d  is capable of acting in accordance with the grant. Thus, the processing time threshold may be defined by a quantity of slots, a quantity of symbols, and the like. In some cases, processing time threshold may include a K0 value, a K1 value, a K2 value, or any combination thereof. 
     At  515 , the UE  115 - d  may receive a DCI message from the base station  105 - b . The UE  115 - d  may receive (and the base station  105 - b  may transmit) the DCI message at  515  based on transmitting/receiving the RRC message at  505 , transmitting/receiving the processing time threshold at  510 , or both. The DCI message may be transmitted via L1 signaling. Additionally, the DCI message may include a unicast transmission, and may include any number of formats for DCI messages (e.g., DCI 11, DCI 1_2). 
     In some aspects, the DCI message may indicate an update to a common beam which is to be performed at the UE  115 - d . For example, the DCI message may indicate a common TCI state for updating the common beam for communications with the UE  115 - d . A TCI state may include at least one source reference signal to provide a reference for the UE  115 - d  to determine a QCL configuration and/or spatial filter for updating the common beam. The common beam which is to be updated in accordance with the DCI message may be shared across multiple channels, multiple reference signals, or both. 
     For instance, the DCI message may indicate a joint uplink/downlink common TCI state configured to update a common beam shared across a downlink channel and an uplink channel, shared across two reference signals, or both. Additionally, the DCI message may indicate a separate downlink-common TCI state configured to update a common beam shared across two downlink channels, shared across two reference signals, or both. Similarly, the DCI message may indicate a separate uplink-common TCI state configured to update a common beam shared across two uplink channels, shared across two reference signals, or both. 
     Additionally, or alternatively, the DCI message may schedule a communication (e.g., PDSCH transmission, PUCCH transmission, PUSCH transmission) between the base station  105 - b  and the UE  115 - d . In some aspects, the timing of the communication scheduled by the DCI message may be based on the processing time threshold at the UE  115 - d . In particular, the base station  105 - b  may schedule the communication via the DCI message in accordance with the processing time threshold based on which common beam should be used at the UE  115 - d  to perform the communication. In this regard, the base station  105 - b  may schedule the communication via the DCI message in order to ensure that the UE  115 - d  does (or does not) have sufficient time to perform the update to the common beam prior to the communication. 
     For instance, the base station  105 - b  may schedule the communication via the DCI message prior to the processing time threshold so that the UE  115 - d  does not have sufficient time to perform the update to the common beam prior to the communication. As such, the base station  105 - b  may be able to control or influence which common beams are used for communications with the UE  115 - d  to perform the scheduled transmission based on a relative timing of the communication with respect to the DCI message. 
     At  520 , the UE  115 - d , the base station  105 - b , or both, may identify which beam update configuration is to be used to implement the update to the common beam. The UE  115 - d  and/or the base station  105 - b  may determine which beam update configuration is to be used based on transmitting/receiving the RRC message at  505 , transmitting/receiving the processing time threshold at  510 , transmitting/receiving the DCI message at  515 , additional or alternative control signaling, or any combination thereof. 
     In some cases, the DCI message may dynamically indicate a beam update configuration which is to be used to update the common beam indicated by the DCI message. For example, in some cases, the beam update configuration which is to be used for implementing the update to the common beam may be indicated dynamically via the DCI message (e.g., without any pre-configuration at the UE  115 - d  or signaling from the base station  105 - b ). In such cases, the DCI message may include an indication of the beam update configuration which is to be used. 
     In other cases, the UE  115 - b  may be pre-configured (e.g., via the RRC message at  505 ) with a beam update configuration which is to be used. In additional or alternative cases, the beam update configuration which is to be used may be signaled via a combination of the RRC message and the DCI message. For example, the RRC message may configure the UE  115 - d  with a set of beam update configurations which may be used. Subsequently, the DCI message may indicate which beam update configuration of the set of beam update configurations is to be used. 
     The relative timing for implementing the update to the common beam may change depending on the beam update configuration which is to be used. For example, according to one beam update configuration, the UE  115 - d  may be configured to update the common beam after performance of the communication scheduled by the DCI message. According to this beam update configuration, the UE  115 - d  may always update the common beam after the scheduled communication regardless of whether the processing time threshold is satisfied at the UE  115 - b . Accordingly, according to this beam update configuration, the process flow  500  may proceed from  520  to  540 ,  545 , and  550 , in which the UE  115 - d  performs the communication scheduled by the DCI message, performs a beam switching procedure to update the common beam after performance of the communication, and performs additional communication in accordance with the updated common beam. These steps will be described in further detail herein. 
     According to another beam update configuration, the relative timing of the update to the common beam may be based on the processing time threshold. In particular, the timing for the update to the common beam may be based on a comparison of the processing time threshold and a time interval between the DCI message and the scheduled communication. In such cases, the process flow  500  may proceed to  525 . 
     At  525 , the UE  115 - d , the base station  105 - b , or both, may identify a time interval between transmission/reception of the DCI message and the scheduled communication. For example, the UE  115 - d  may identify a time interval between reception of the DCI message and a time at which the scheduled communication is to be performed (e.g., a time at which the scheduled communication is to be transmitted or received). As such, the UE  115 - d  and/or the base station may identify the time interval at  525  based on transmitting/receiving the RRC message at  505 , transmitting/receiving the processing time threshold at  510 , transmitting/receiving the DCI message at  515 , identifying the beam update configuration at  520 , identifying a time at which the communication scheduled by the DCI message is to be performed, or any combination thereof. The time interval may include a quantity of slots, a quantity of symbols, and the like. 
     At  530 , the UE  115 - d , the base station  105 - b , or both, may compare the time interval with the processing timeline (e.g., processing time threshold) at the UE  115 - d . In some aspects, the UE  115 - d  and/or the base station may perform the comparison at  530  based on transmitting/receiving the RRC message at  505 , transmitting/receiving the processing time threshold at  510 , transmitting/receiving the DCI message at  515 , identifying the beam update configuration at  520 , identifying a time at which the communication scheduled by the DCI message is to be performed, identifying the time interval at  525 , or any combination thereof. 
     As noted previously herein, the time interval may define a time duration between the DCI message and the communication scheduled by the DCI message. Similarly, the time interval may define a time duration between the DCI message and a time at which the UE  115 - d  is capable of acting in accordance with the DCI message (e.g., performing the transmission scheduled by the DCI message). As such, in some cases, both the time interval and the processing time threshold may be based on a time at which the DCI message was transmitted/received. However, the time duration, the processing time threshold, and/or other time durations (e.g., minimum beam indication delay) may be measured and/or initiated relative to additional or alternative points in time, such as a time at which DCI message was acknowledged (e.g., time of ACK/NACK responsive to DCI message). 
     According to some beam update configurations, the relative timing of the update to the common beam may be based on the comparison of the time interval (T Int ) and the processing time threshold (PT Thresh ). In particular, the relative timing of the update to the common beam may be based on whether or not the time interval satisfies the processing time threshold. In some aspects, the time interval may satisfy the processing time threshold if the time interval is greater than or equal to the processing threshold (e.g., processing timeline satisfied if T Int ≥PT Thresh ). In this regard, the communication scheduled by the DCI message may be scheduled after an end of the processing time threshold, thereby satisfying the processing time threshold and providing the UE  115 - d  with sufficient time to process the DCI message and perform the beam switching procedure (e.g., radio frequency component retuning). 
     Conversely, the time interval may fail to satisfy the processing time threshold if the time interval is less than the processing threshold (e.g., processing timeline not satisfied if T Int &lt;PT Thresh ). In this regard, the communication scheduled by the DCI message may be scheduled before an end of the processing time threshold, thereby failing to satisfy the processing time threshold due to the fact that the UE  115 - d  may not have sufficient time to process the DCI message and perform the beam switching procedure (e.g., radio frequency component retuning). 
     Accordingly, in some aspects, the UE  115 - d  may be configured to perform at least one beam switching procedure after performance of the communication scheduled by the DCI message if the time interval fails to satisfy the processing time threshold (e.g., update common beam after scheduled communication if T Int &lt;PT Thresh ). Conversely, the UE  115 - d  may be configured to perform at least one beam switching procedure prior to performance of the communication scheduled by the DCI message if the time interval satisfies the processing time threshold (e.g., update common beam before scheduled communication if T Int ≥PT Thresh ). 
     At  535 , the UE  115 - d  may perform at least one beam switching procedure to update the common beam. In some aspects, the UE  115 - d  may perform the at least one beam switching procedure based on the DCI message and in accordance with the beam update configuration. In this regard, the UE  115 - d  may update the common beam at  535  based on receiving the RRC message at  505 , transmitting the processing time threshold at  510 , receiving the DCI message at  515 , identifying the beam update configuration at  520 , identifying the time interval at  525 , comparing the time interval and the processing time threshold at  530 , or any combination thereof. For example, the UE  115 - d  may perform the at least one beam switching procedure based on (e.g., in accordance with) a common TCI state indicated in the DCI message. 
     For example, according to some beam update configurations, the UE  115 - d  may perform the beam switching procedure to update the common beam at  535  prior to performing the communication scheduled by the DCI message based on the comparison of the time interval and the processing time threshold at  530 . In particular, according to some beam update configurations, the UE  115 - d  may perform the beam switching procedure to update the common beam at  535  prior to performing the communication scheduled by the DCI message if the time interval satisfies the processing time threshold (e.g., update common beam before scheduled communication at  535  if T Int ≥PT Thresh ). 
     At  540 , the UE  115 - d  may perform the communication scheduled by the DCI message. The communication may include a PDSCH transmission, a PUCCH transmission, a PUSCH transmission, or any combination thereof. In some aspects, the UE  115 - d  may perform the communication scheduled by the DCI message based on performing the at least one beam switching procedure at  535 . In this regard, the UE  115 - d  may perform the communication scheduled by the DCI message using the updated common beam. For example, in cases where the time interval satisfies the processing time threshold (e.g., T Int ≥PT Thresh ), the UE  115 - d  may update the common beam at  535 , and may perform the communication at  540  using the updated common beam. 
     In additional or alternative cases, the UE  115 - d  may not perform the beam switching procedure at  535  prior to performing the communication at  540 . For example, cases where the time interval fails to satisfy the processing time threshold (e.g., T Int &lt;PT Thresh ), the UE  115 - d  may refrain from performing the beam switching procedure at  535 . In such cases, the UE  115 - d  may perform the communication at  540  using the same common beam which was used to receive the DCI message at  515 . Thus, in cases where the UE  115 - d  refrains from performing the beam switching procedure at  535 , the UE  115 - d  may perform the communication at  540 , and the process flow  500  may proceed to  545 . 
     At  545 , the UE  115 - d  may perform at least one beam switching procedure to update the common beam. In some aspects, the UE  115 - d  may perform the at least one beam switching procedure based on the DCI message and in accordance with the beam update configuration. In this regard, the UE  115 - d  may update the common beam at  545  based on receiving the RRC message at  505 , transmitting the processing time threshold at  510 , receiving the DCI message at  515 , identifying the beam update configuration at  520 , identifying the time interval at  525 , comparing the time interval and the processing time threshold at  530 , performing the communication at  540 , or any combination thereof. For example, the UE  115 - d  may perform the at least one beam switching procedure based on (e.g., in accordance with) a common TCI state indicated in the DCI message. Moreover, the UE  115 - d  may perform the beam switching procedure at  545  based on refraining from performing the beam switching procedure prior to the scheduled communication at  535 . 
     For example, according to some beam update configurations, the UE  115 - d  may perform the beam switching procedure to update the common beam at  545  after performing the communication scheduled by the DCI message based on the comparison of the time interval and the processing time threshold at  530 . In particular, according to some beam update configurations, the UE  115 - d  may perform the beam switching procedure to update the common beam at  545  after performing the communication scheduled by the DCI message if the time interval fails to satisfy the processing time threshold (e.g., update common beam after scheduled communication at  545  if T Int &lt;PT Thresh ). By performing the beam switching procedure at  545  after performance of the communication, the UE  115 - d  may be configured to perform the communication at  540  with the same common beam which was used to receive the DCI message at  515 . 
     At  550 , the UE  115 - d  may perform additional communications (e.g., PDCCH transmissions, PDSCH transmissions, PUCCH transmissions, PUSCH transmissions). with the base station  105 - b . In some aspects, the UE  115 - d  may perform the additional communications with the base station  105 - b  based on performing the at least one beam switching procedure at  535 , the at least one beam switching procedure  545 , or both. In this regard, the UE  115 - d  may perform the additional communications using an updated common beam which was generated based on the beam switching procedure(s). 
     The techniques described herein may provide signaling and other configurations which indicate when the UE  115 - d  should implement updates to common beams. As such, the techniques described herein may enable the base station  105 - b  to update multiple beams (e.g., a common beam) at the UE  115 - d  using a single DCI message. In this regard, techniques described herein may thereby reduce control signaling overhead and improve resource utilization in the wireless communications system. Moreover, by providing beam update configurations which define timings for implementing updates to common beams, techniques described herein may improve the speed and efficiency with which beams may be updated at the UE  115 - d , thereby improving the efficiency of wireless communications within the wireless communications system. 
       FIG. 6  shows a block diagram  600  of a device  605  that supports techniques for common beam update rules for scheduled communications in accordance with aspects of the present disclosure. The device  605  may be an example of aspects of a UE  115  as described herein. The device  605  may include a receiver  610 , a transmitter  615 , and a communications manager  620 . The device  605  may also include a processor. Each of these components may be in communication with one another (e.g., via one or more buses). 
     The receiver  610  may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for common beam update rules for scheduled communications). Information may be passed on to other components of the device  605 . The receiver  610  may utilize a single antenna or a set of multiple antennas. 
     The transmitter  615  may provide a means for transmitting signals generated by other components of the device  605 . For example, the transmitter  615  may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for common beam update rules for scheduled communications). In some examples, the transmitter  615  may be co-located with a receiver  610  in a transceiver module. The transmitter  615  may utilize a single antenna or a set of multiple antennas. 
     The communications manager  620 , the receiver  610 , the transmitter  615 , or various combinations thereof or various components thereof may be examples of means for performing various aspects of techniques for common beam update rules for scheduled communications as described herein. For example, the communications manager  620 , the receiver  610 , the transmitter  615 , or various combinations or components thereof may support a method for performing one or more of the functions described herein. 
     In some examples, the communications manager  620 , the receiver  610 , the transmitter  615 , or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry). The hardware may include a processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing the functions described in the present disclosure. In some examples, a processor and memory coupled with the processor may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor, instructions stored in the memory). 
     Additionally or alternatively, in some examples, the communications manager  620 , the receiver  610 , the transmitter  615 , or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by a processor. If implemented in code executed by a processor, the functions of the communications manager  620 , the receiver  610 , the transmitter  615 , or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting a means for performing the functions described in the present disclosure). 
     In some examples, the communications manager  620  may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver  610 , the transmitter  615 , or both. For example, the communications manager  620  may receive information from the receiver  610 , send information to the transmitter  615 , or be integrated in combination with the receiver  610 , the transmitter  615 , or both to receive information, transmit information, or perform various other operations as described herein. 
     The communications manager  620  may support wireless communication at a UE in accordance with examples as disclosed herein. For example, the communications manager  620  may be configured as or otherwise support a means for receiving control signaling indicating a beam update configuration that defines a timing for updating a common beam for communications with the UE in relation to a communication and in response to a DCI message that schedules the communication and indicates an update to the common beam, where the common beam is shared across a set of multiple channels, a set of multiple reference signals, or both.

By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media. 
     As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of”) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.” 
     In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label, or other subsequent reference label. 
     The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration,” and not “preferred” or “advantageous over other examples.” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples. 
     The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
