Title: Overlapping an uplink dynamic grant with a configured uplink transmission

Description:
INTRODUCTION 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for scheduling an uplink transmission. 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). 
     A wireless communication network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, and/or the like. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

     DETAILED DESCRIPTION 
     A user equipment (UE) may be configured with a beam that is to be used for transmitting a configured uplink transmission. In some cases, the beam may not be permitted for use in transmitting the configured uplink transmission, such as when the beam is directed toward a human body. As a result, an uplink performance of the UE may be impaired, and configuration of a new beam for the UE may be associated with latencies that further impair uplink performance. According to some techniques and apparatuses described herein, a UE may receive a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission that is to be transmitted on a beam that is not permitted for use. Accordingly, the UE may transmit the uplink transmission punctured in the configured uplink transmission. In this way, uplink performance of the UE may be improved. 
     Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, and/or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     It should be noted that while aspects may be described herein using terminology commonly associated with 3G and/or 4G wireless technologies, aspects of the present disclosure can be applied in other generation-based communication systems, such as 5G and later, including NR technologies. 
       FIG.  1    is a diagram illustrating a wireless network  100  in which aspects of the present disclosure may be practiced. The wireless network  100  may be an LTE network, a 5G or NR network, and/or the like. The wireless network  100  may include a number of base stations (BSs)  110  (shown as BS  110   a , BS  110   b , BS  110   c , and BS  110   d ) and other network entities. A BS is an entity that communicates with UEs and may also be referred to as a base station, a NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and/or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used. 
     ABS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. ABS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in  FIG.  1   , a BS  110   a  may be a macro BS for a macro cell  102   a , a BS  110   b  may be a pico BS for a pico cell  102   b , and a BS  110   c  may be a femto BS for a femto cell  102   c . ABS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein. 
     In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some examples, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces such as a direct physical connection, a virtual network, and/or the like using any suitable transport network. 
     Wireless network  100  may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in  FIG.  1   , a relay station  110   d  may communicate with macro BS  110   a  and a UE  120   d  in order to facilitate communication between BS  110   a  and UE  120   d . A relay station may also be referred to as a relay BS, a relay base station, a relay, and/or the like. 
     Wireless network  100  may be a heterogeneous network that includes BSs of different types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network  100 . For example, macro BSs may have a high transmit power level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 Watts). 
     A network controller  130  may couple to a set of BSs and may provide coordination and control for these BSs. Network controller  130  may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul. 
     UEs  120  (e.g.,  120   a ,  120   b ,  120   c ) may be dispersed throughout wireless network  100 , and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium. 
     Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, and/or the like, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE  120  may be included inside a housing that houses components of UE  120 , such as processor components, memory components, and/or the like. 
     In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, and/or the like. A frequency may also be referred to as a carrier, a frequency channel, and/or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. 
     As shown in  FIG.  1   , the UE  120  may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may receive a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission, transmit the uplink transmission punctured in the configured uplink transmission based at least in part on receiving the dynamic grant, and/or the like. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     Similarly, the base station  110  may include a communication manager  150 . As described in more detail elsewhere herein, the communication manager  150  may transmit to a UE a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission of the UE, receive from the UE the uplink transmission punctured in the configured uplink transmission based at least in part on transmitting the dynamic grant, and/or the like. Additionally, or alternatively, the communication manager  150  may perform one or more other operations described herein. 
     As indicated above,  FIG.  1    is provided merely as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIG.  2    shows a block diagram of a design  200  of base station  110  and UE  120 , which may be one of the base stations and one of the UEs in  FIG.  1   . Base station  110  may be equipped with T antennas  234   a  through  234   t , and UE  120  may be equipped with R antennas  252   a  through  252   r , where in general T≥1 and R≥1. 
     At base station  110 , a transmit processor  220  may receive data from a data source  212  for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor  220  may also process system information (e.g., for semi-static resource partitioning information (SRPI) and/or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and/or the like) and provide overhead symbols and control symbols. Transmit processor  220  may also generate reference symbols for reference signals (e.g., the cell-specific reference signal (CRS)) and synchronization signals (e.g., the primary synchronization signal (PSS) and secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs)  232   a  through  232   t . Each modulator  232  may process a respective output symbol stream (e.g., for OFDM and/or the like) to obtain an output sample stream. Each modulator  232  may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators  232   a  through  232   t  may be transmitted via T antennas  234   a  through  234   t , respectively. According to various aspects described in more detail below, the synchronization signals can be generated with location encoding to convey additional information. 
     At UE  120 , antennas  252   a  through  252   r  may receive the downlink signals from base station  110  and/or other base stations and may provide received signals to demodulators (DEMODs)  254   a  through  254   r , respectively. Each demodulator  254  may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator  254  may further process the input samples (e.g., for OFDM and/or the like) to obtain received symbols. A MIMO detector  256  may obtain received symbols from all R demodulators  254   a  through  254   r , perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE  120  to a data sink  260 , and provide decoded control information and system information to a controller/processor  280 . A channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), and/or the like. In some aspects, one or more components of UE  120  may be included in a housing. 
     On the uplink, at UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor  280 . Transmit processor  264  may also generate reference symbols for one or more reference signals. The symbols from transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by modulators  254   a  through  254   r  (e.g., for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to base station  110 . At base station  110 , the uplink signals from UE  120  and other UEs may be received by antennas  234 , processed by demodulators  232 , detected by a MIMO detector  236  if applicable, and further processed by a receive processor  238  to obtain decoded data and control information sent by UE  120 . Receive processor  238  may provide the decoded data to a data sink  239  and the decoded control information to controller/processor  240 . Base station  110  may include communication unit  244  and communicate to network controller  130  via communication unit  244 . Network controller  130  may include communication unit  294 , controller/processor  290 , and memory  292 . 
     Controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG.  2    may perform one or more techniques associated with overlapping an uplink dynamic grant with a configured uplink transmission, as described in more detail elsewhere herein. For example, controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG.  2    may perform or direct operations of, for example, process  800  of  FIG.  8   , process  900  of  FIG.  9   , and/or other processes as described herein. Memories  242  and  282  may store data and program codes for base station  110  and UE  120 , respectively. A scheduler  246  may schedule UEs for data transmission on the downlink and/or uplink. 
     In some aspects, the UE  120  may include means for receiving a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission, means for transmitting the uplink transmission punctured in the configured uplink transmission based at least in part on receiving the dynamic grant, and/or the like. Additionally, or alternatively, the UE  120  may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager  140 . Additionally, or alternatively, such means may include one or more components of the UE  120  described in connection with  FIG.  2   . 
     In some aspects, the base station  110  may include means for transmitting to a UE a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission of the UE, means for receiving from the UE the uplink transmission punctured in the configured uplink transmission based at least in part on transmitting the dynamic grant, and/or the like. Additionally, or alternatively, the base station  110  may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager  150 . In some aspects, such means may include one or more components of the base station  110  described in connection with  FIG.  2   . 
     As indicated above,  FIG.  2    is provided merely as an example. Other examples may differ from what is described with regard to  FIG.  2   . 
       FIG.  3    is a diagram illustrating an example  300  of communication involving a maximum permissible exposure (MPE) event, in accordance with various aspects of the present disclosure. As shown in  FIG.  3   , a UE and a BS may be capable of communicating via one or more beams, and a communication via a beam may take multiple different paths to reach a receiver. In some cases, a beam may be a millimeter wave (mmWave) beam that carries a communication in the mmWave frequency band. When transmitting in the mmWave frequency band, a transmitter may use a higher antenna gain as compared to transmitting in the sub-6 gigahertz (GHz) frequency band. As a result, the effective isotropic radiated power (EIRP), which represents the radiated power in a particular direction (e.g., the direction of the beam), may be higher for mmWave communications as compared to sub-6 GHz communications. To improve safety, some governing bodies have placed restrictions on the peak EIRP that can be directed toward the human body. These restrictions are sometimes referred to as MPE limitations, MPE constraints, and/or the like. 
     As shown in  FIG.  3   , and by reference number  305 , the UE may communicate with the BS using an uplink beam and/or a downlink beam. In some cases, the uplink beam used by the UE may not be directed toward a human body, or the like, and therefore may not be subject to an MPE condition. 
     As shown by reference number  310 , the uplink beam used by the UE to transmit an uplink communication may become subject to an MPE condition. For example, the uplink beam may become subject to the MPE condition upon the occurrence of an MPE event. The MPE event may be a human body  315 , or the like, blocking the beam (i.e., the beam used by the UE to transmit the uplink transmission may be directed toward the human body  315 ). That is, the human body  315  may block or obstruct communications to and/or from an antenna subarray of the UE, or may otherwise be positioned near the antenna subarray. In this case, the downlink beam may be suitable for use by the UE to communicate with the BS, but the uplink beam may not be permitted for use when the uplink beam is subject to the MPE condition. 
     As shown by reference number  320 , in some aspects, the UE may transmit an uplink transmission using a different beam than the beam that is subject to the MPE condition. For example, the UE may use a beam directed toward an object  325  that provides a path to the BS that is not blocked by the human body  315 . 
     As indicated above,  FIG.  3    is provided as an example. Other examples may differ from what is described with respect to  FIG.  3   . 
       FIG.  4    is a diagram illustrating an example  400  of communication involving an MPE event, in accordance with various aspects of the present disclosure. As shown in  FIG.  4   , a UE may transmit a first uplink transmission, such as a first SRS (SRS1), using a first beam  405 , and a second uplink transmission, such as a second SRS (SRS2), using a second beam  410 . In some cases, an MPE event  415  may occur with respect to a beam used by the UE. For example, the second beam  410  may be directed toward a human body, and thus the second beam  410  may be subject to an MPE condition. As shown in  FIG.  4   , the UE may discontinue use of the second beam  410  for transmitting the second SRS when the second beam  410  is subject to the MPE condition. 
     As a result of the MPE condition, an uplink performance of the UE may be impaired. Moreover, reconfiguration (e.g., radio resource control (RRC) reconfiguration) of a new beam for the UE may be associated with latencies that further impair the uplink performance of the UE. According to some techniques and apparatuses described herein, a UE may receive a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission (e.g., an SRS transmission on a beam that is subject to an MPE condition). Accordingly, the UE may transmit the uplink transmission punctured in the configured uplink transmission. In this way, uplink performance of the UE may be improved, such as when a beam of the UE is subject to an MPE condition. 
     As indicated above,  FIG.  4    is provided as an example. Other examples may differ from what is described with respect to  FIG.  4   . 
       FIG.  5    is a diagram illustrating an example  500  of overlapping an uplink dynamic grant with a configured uplink transmission, in accordance with various aspects of the present disclosure. As shown in  FIG.  5   , a BS  110  and a UE  120  may communicate in connection with one or more uplink transmissions. 
     As shown by reference number  505 , the UE  120  may transmit, and the BS  110  may receive, a series of configured uplink transmissions. A configured uplink transmission may be a periodic SRS, a semi-periodic SRS, a type-1 configured grant physical uplink shared channel (PUSCH) communication, or a physical uplink control channel (PUCCH) communication. For example, as shown, the UE  120  may periodically transmit a first SRS (SRS1) using a first beam  525  and a second SRS (SRS2) using a second beam  530 . Such configured uplink transmissions may be configured by higher layer signaling, such as by RRC signaling, from the BS  110  to the UE  120 . Moreover, such configured uplink transmissions may be modified, for example by RRC reconfiguration (which may be associated with significant latency). 
     As shown in  FIG.  5   , an MPE event  510  may occur during communication of the series of configured uplink transmissions. As described above, the MPE event  510  may be a human body blocking a beam of the UE  120 . Accordingly, the beam to which the MPE event  510  relates may be subject to an MPE condition, and therefore not permitted for use by the UE  120 . For example, as shown, the second beam  530  may be subject to an MPE condition, and therefore not permitted for use by the UE  120 . In this case, the UE  120  may continue to transmit the first SRS using the first beam  525 , and may discontinue transmitting the second SRS using the second beam  530 . 
     In some aspects, the UE  120  may determine that a beam (e.g., the second beam  530 ) is not to be used due to the MPE condition. That is, the UE  120  may determine that the beam is subject to the MPE condition, and therefore not permitted for use by the UE  120 . In some aspects, the UE  120  may detect the MPE event  510 , to thereby determine that the beam is subject to the MPE condition. For example, the UE  120  may detect that the beam is directed at a human body (e.g., using ultrasound, or the like). In some aspects, the UE  120  may transmit, and the BS  110  may receive, an indication that the beam (e.g., the second beam  530 ) is not to be used by the UE  120  due to being subject to the MPE condition. In some aspects, the indication also may identify another beam that the UE  120  could use instead of the beam subject to the MPE condition. 
     As shown by reference number  515 , the BS  110  may transmit, and the UE  120  may receive, a dynamic grant for an uplink transmission. For example, the BS  110  may transmit the dynamic grant for the uplink transmission based at least in part on receiving the indication of the MPE condition from the UE  120 . In some aspects, the uplink transmission may be a PUSCH communication, an aperiodic SRS, or a physical random access channel (PRACH) communication. 
     In some aspects, the BS  110  may transmit downlink control information (DCI) that indicates the dynamic grant for the uplink transmission. In some aspects, the DCI may also indicate a beam that the UE  120  is to use to transmit the uplink transmission. 
     The dynamic grant for the uplink transmission may overlap (e.g., in a time domain) with a particular configured uplink transmission. That is, the dynamic grant may overlap with a particular configured uplink transmission that is to be transmitted using the beam subject to the MPE condition. In some aspects, the dynamic grant (e.g., the DCI that indicates the dynamic grant) may be received by the UE  120  at least a threshold quantity of symbols before the particular configured uplink transmission, as described in connection with  FIG.  6   . 
     As shown by reference numbers  520   a  and  520   b , the UE  120  may transmit, and the BS  110  may receive, the uplink transmission punctured in the particular configured uplink transmission according to the dynamic grant. As shown by reference number  520   a , the uplink transmission may be an aperiodic SRS (A-SRS3), and the UE  120  may transmit the aperiodic SRS, punctured in the particular configured uplink transmission, using a third beam  535 . As shown by reference number  520   b , the uplink transmission may be a PUSCH communication, and the UE  120  may transmit the PUSCH communication, punctured in the particular configured uplink transmission, using the first beam  525 . In some aspects, the UE  120  may partially puncture or fully puncture the configured uplink transmission, as described in connection with  FIG.  7   . In this way, the UE  120  may efficiently use time domain resources for uplink transmissions, thereby improving throughput and an uplink performance of the UE  120 . 
     As indicated above,  FIG.  5    is provided as an example. Other examples may differ from what is described with respect to  FIG.  5   . 
       FIG.  6    is a diagram illustrating an example  600  of overlapping an uplink dynamic grant with a configured uplink transmission, in accordance with various aspects of the present disclosure. As shown in  FIG.  6   , a BS  110  and a UE  120  may communicate in connection with one or more uplink transmissions. For example, the BS  110  and the UE  120  may communicate in connection with a series of configured uplink transmissions using one or more beams, as described in connection with  FIG.  5   . A beam used by the UE  120  to transmit a configured uplink transmission may be subject to an MPE condition upon the occurrence of an MPE event  610 , as described in connection with  FIG.  5   . 
     After the occurrence of the MPE event  610 , the BS  110  may transmit, and the UE  120  may receive, DCI that indicates a dynamic grant for an uplink transmission that overlaps with a particular configured uplink transmission, as described in connection with  FIG.  5   . The DCI (e.g., the dynamic grant) may be received by the UE  120  a threshold quantity of symbols  615  before the particular configured uplink transmission is scheduled. Accordingly, a timing of a first transmission opportunity  620  after the DCI is received by the UE  120  may not satisfy the threshold quantity of symbols  615  and may not be used for the uplink transmission, while a timing of a second transmission opportunity  625  may satisfy the threshold quantity of symbols  615  and may be used for the uplink transmission. 
     In some aspects, the threshold quantity of symbols  615  may be a fixed value or a value that may be based at least in part on a numerology of a carrier (e.g., a carrier on which the UE  120  and the BS  110  are communicating). For example, the value may be based at least in part on a subcarrier spacing. In some aspects, the threshold quantity of symbols  615  may be based at least in part on a type of the uplink transmission (e.g., aperiodic SRS, PUSCH communication, or PRACH communication) and/or a capability of the UE  120 . For example, the threshold quantity of symbols  615  may be greater than a quantity of symbols that is needed by the UE  120  to prepare an SRS (e.g., according to an SRS processing capability of the UE  120 ), a quantity of symbols that is needed by the UE  120  to prepare a PUSCH (e.g., according to a PUSCH processing capability of the UE  120 ), a quantity of symbols that is needed by the UE  120  to prepare a PRACH (e.g., according to a PRACH processing capability of the UE  120 ), and/or the like. 
     As indicated above,  FIG.  6    is provided as an example. Other examples may differ from what is described with respect to  FIG.  6   . 
       FIG.  7    is a diagram illustrating an example  700  of overlapping an uplink dynamic grant with a configured uplink transmission, in accordance with various aspects of the present disclosure. For example, as shown in  FIG.  7   , a dynamic grant for an uplink transmission  715  (e.g., a dynamic grant for an uplink transmission as described in connection with  FIGS.  5  and  6   ) may overlap with a configured uplink transmission  720  (e.g., a configured uplink transmission as described in connection with  FIGS.  5  and  6   ). Accordingly, the uplink transmission  715  may be punctured in the configured uplink transmission, as described above. 
     As shown by reference number  705 , in some aspects, only resources (e.g., time domain resources, such as symbols) for the configured uplink transmission  720  that overlap with the dynamic grant for the uplink transmission  715  may be punctured (e.g., such that the non-punctured symbols for the configured uplink transmission  720  may be transmitted). For example, one or more symbols of the configured uplink transmission  720  that overlap with the dynamic grant for the uplink transmission  715  may be punctured, and one or more symbols of the configured uplink transmission  720  that do not overlap with the dynamic grant for the uplink transmission  715  may not be punctured. As shown by reference number  710 , in some aspects, all resources (e.g., time domain resources) for the configured uplink transmission  720  may be punctured. For example, one or more symbols of the configured uplink transmission may be punctured regardless of whether the symbols overlap with the dynamic grant for the uplink transmission  715 . 
     As indicated above,  FIG.  7    is provided as an example. Other examples may differ from what is described with respect to  FIG.  7   . 
       FIG.  8    is a diagram illustrating an example process  800  performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process  800  is an example where the UE (e.g., UE  120 , and/or the like) performs operations associated with overlapping an uplink dynamic grant with a configured uplink transmission. 
     As shown in  FIG.  8   , in some aspects, process  800  may include receiving a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission (block  810 ). For example, the UE (e.g., using antenna  252 , DEMOD  254 , MIMO detector  256 , receive processor  258 , controller/processor  280 , and/or the like) may receive a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission, as described above. 
     As further shown in  FIG.  8   , in some aspects, process  800  may include transmitting the uplink transmission punctured in the configured uplink transmission based at least in part on receiving the dynamic grant (block  820 ). For example, the UE (e.g., using controller/processor  280 , transmit processor  264 , TX MIMO processor  266 , MOD  254 , antenna  252 , and/or the like) may transmit the uplink transmission punctured in the configured uplink transmission based at least in part on receiving the dynamic grant, as described above. 
     Process  800  may include additional aspects, such as any single aspect or any combination of aspects described below and/or in connection with one or more other processes described elsewhere herein. 
     In a first aspect, a beam for transmitting the configured uplink transmission is subject to an MPE condition. In a second aspect, alone or in combination with the first aspect, process  800  includes determining that a beam for the configured uplink transmission is not to be used, due to an MPE condition, and transmitting an indication that the beam is not to be used due to the MPE condition. 
     In a third aspect, alone or in combination with one or more of the first and second aspects, the uplink transmission is a PUSCH communication, an aperiodic SRS, or a PRACH communication. In a fourth aspect, alone or in combination with one or more of the first through third aspects, the configured uplink transmission is a periodic SRS, a semi-periodic SRS, a type-1 configured grant PUSCH communication, or a PUCCH communication. 
     In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, one or more symbols of the configured uplink transmission that overlap with the dynamic grant for the uplink transmission are punctured, and one or more symbols of the configured uplink transmission that do not overlap with the dynamic grant for the uplink transmission are not punctured. In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, all resources for the configured uplink transmission are punctured. 
     In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the dynamic grant is received at least a threshold quantity of symbols before the configured uplink transmission is scheduled. In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, the threshold quantity of symbols is a fixed value or a value that is based at least in part on a numerology of a carrier. In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the threshold quantity of symbols is based at least in part on at least one of a type of the uplink transmission or a capability of the UE. 
     Although  FIG.  8    shows example blocks of process  800 , in some aspects, process  800  may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in  FIG.  8   . Additionally, or alternatively, two or more of the blocks of process  800  may be performed in parallel. 
       FIG.  9    is a diagram illustrating an example process  900  performed, for example, by a BS, in accordance with various aspects of the present disclosure. Example process  900  is an example where the BS (e.g., BS  110 , and/or the like) performs operations associated with overlapping an uplink dynamic grant with a configured uplink transmission. 
     As shown in  FIG.  9   , in some aspects, process  900  may include transmitting to a UE a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission of the UE (block  910 ). For example, the BS (e.g., using controller/processor  240 , transmit processor  220 , TX MIMO processor  230 , MOD  232 , antenna  234 , and/or the like) may transmit to a UE a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission of the UE, as described above. 
     As further shown in  FIG.  9   , in some aspects, process  900  may include receiving from the UE the uplink transmission punctured in the configured uplink transmission based at least in part on transmitting the dynamic grant (block  920 ). For example, the BS (e.g., using antenna  234 , DEMOD  232 , MIMO detector  236 , receive processor  238 , controller/processor  240 , and/or the like) may receive from the UE the uplink transmission punctured in the configured uplink transmission based at least in part on transmitting the dynamic grant, as described above. 
     Process  900  may include additional aspects, such as any single aspect or any combination of aspects described below and/or in connection with one or more other processes described elsewhere herein. 
     In a first aspect, a beam that the UE is to use for transmitting the configured uplink transmission is subject to an MPE condition. In a second aspect, alone or in combination with the first aspect, process  900  includes receiving an indication that a beam that the UE is to use for transmitting the configured uplink transmission is not to be used by the UE due to an MPE condition. 
     In a third aspect, alone or in combination with one or more of the first and second aspects, the uplink transmission is a PUSCH communication, an aperiodic SRS, or a PRACH communication. In a fourth aspect, alone or in combination with one or more of the first through third aspects, the configured uplink transmission is a periodic SRS, a semi-periodic SRS, a type-1 configured grant PUSCH communication, or a PUCCH communication. 
     In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, one or more symbols of the configured uplink transmission that overlap with the dynamic grant for the uplink transmission are punctured, and one or more symbols of the configured uplink transmission that do not overlap with the dynamic grant for the uplink transmission are not punctured. In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, all resources for the configured uplink transmission are punctured. 
     In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the dynamic grant is transmitted at least a threshold quantity of symbols before the configured uplink transmission is scheduled. In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, the threshold quantity of symbols is a fixed value or a value that is based at least in part on a numerology of a carrier. In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the threshold quantity of symbols is based at least in part on at least one of a type of the uplink transmission or a capability of the UE. 
     Although  FIG.  9    shows example blocks of process  900 , in some aspects, process  900  may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in  FIG.  9   . Additionally, or alternatively, two or more of the blocks of process  900  may be performed in parallel.
