Title: Bandwidth part switch with wake up signal

Description:
FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for an integrated wake up signal and bandwidth part switch sequence. 
     BACKGROUND 
     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, 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 network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 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, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

     DETAILED DESCRIPTION 
     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. 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, 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. 
     While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G). 
       FIG.  1    is a diagram illustrating an example of a wireless network  100 , in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network  100  may include one or more base stations  110  (shown as a BS  110   a , a BS  110   b , a BS  110   c , and a BS  110   d ), a user equipment (UE)  120  or multiple UEs  120  (shown as a UE  120   a , a UE  120   b , a UE  120   c , a UE  120   d , and a UE  120   e ), and/or other network entities. A UE may also be referred to a “mobile station”. A base station  110  is an entity that communicates with UEs  120 . A base station  110  (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), a roadside unit (RSU), an access point, and/or a transmission reception point (TRP). Each base station  110  may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station  110  and/or a base station subsystem serving this coverage area, depending on the context in which the term is used. 
     A base station  110  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  120  with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs  120  with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs  120  having association with the femto cell (e.g., UEs  120  in a closed subscriber group (CSG)). A base station  110  for a macro cell may be referred to as a macro base station. A base station  110  for a pico cell may be referred to as a pico base station. A base station  110  for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in  FIG.  1   , the BS  110   a  may be a macro base station for a macro cell  102   a , the BS  110   b  may be a pico base station for a pico cell  102   b , and the BS  110   c  may be a femto base station for a femto cell  102   c . A base station may support one or multiple (e.g., three) cells. 
     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 base station  110  that is mobile (e.g., a mobile base station). In some examples, the base stations  110  may be interconnected to one another and/or to one or more other base stations  110  or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     The wireless network  100  may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station  110  or a UE  120 ) and send a transmission of the data to a downstream station (e.g., a UE  120  or a base station  110 ). A relay station may be a UE  120  that can relay transmissions for other UEs  120 . In the example shown in  FIG.  1   , the BS  110   d  (e.g., a relay base station) may communicate with the BS  110   a  (e.g., a macro base station) and the UE  120   d  in order to facilitate communication between the BS  110   a  and the UE  120   d . A base station  110  that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. 
     The wireless network  100  may be a heterogeneous network that includes base stations  110  of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, RSUs, or the like. These different types of base stations  110  may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network  100 . For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts). 
     A network controller  130  may couple to or communicate with a set of base stations  110  and may provide coordination and control for these base stations  110 . The network controller  130  may communicate with the base stations  110  via a backhaul communication link. The base stations  110  may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. 
     The UEs  120  may be dispersed throughout the wireless network  100 , and each UE  120  may be stationary or mobile. A UE  120  may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE  120  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, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium. 
     Some UEs  120  may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs  120  may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs  120  may be considered a Customer Premises Equipment. A UE  120  may be included inside a housing that houses components of the UE  120 , such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. 
     In general, any number of wireless networks  100  may be deployed in a given geographic area. Each wireless network  100  may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, 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. 
     In some examples, two or more UEs  120  (e.g., shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (e.g., without using a base station  110  as an intermediary to communicate with one another). For example, the UEs  120  may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     Devices of the wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network  100  may communicate using one or more operating bands. In 5GNR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. 
     The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band. 
     With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     In some aspects, a first mobile station (e.g., UE  120 ) may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may select a sequence that is to be used by a second mobile station to wake up and switch to a bandwidth part (BWP) indicated by the sequence and transmit the sequence to the second mobile station. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     In some aspects, a second mobile station (e.g., UE  120 ) may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may receive a sequence that is to be used by the second mobile station to wake up and switch to a BWP indicated by the sequence. The communication manager  140  may switch to the BWP after waking up in connection with receiving the sequence. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     As indicated above,  FIG.  1    is provided as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIG.  2    is a diagram illustrating an example  200  of a base station  110  in communication with a UE  120  in a wireless network  100 , in accordance with the present disclosure. The base station  110  may be equipped with a set of antennas  234   a  through  234   t , such as T antennas (T ≥ 1). The UE  120  may be equipped with a set of antennas  252   a  through  252   r , such as R antennas (R ≥ 1). 
     At the base station  110 , a transmit processor  220  may receive data, from a data source  212 , intended for the UE  120  (or a set of UEs  120 ). The transmit processor  220  may select one or more modulation and coding schemes (MCSs) for the UE  120  based at least in part on one or more channel quality indicators (CQIs) received from that UE  120 . The base station  110  may process (e.g., encode and modulate) the data for the UE  120  based at least in part on the MCS(s) selected for the UE  120  and may provide data symbols for the UE  120 . The transmit processor  220  may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor  220  may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a 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 a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems  232  (e.g., T modems), shown as modems  232   a  through  232   t . For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem  232 . Each modem  232  may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem  232  may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems  232   a  through  232   t  may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas  234  (e.g., T antennas), shown as antennas  234   a  through  234   t . 
     At the UE  120 , a set of antennas  252  (shown as antennas  252   a  through  252   r ) may receive the downlink signals from the base station  110  and/or other base stations  110  and may provide a set of received signals (e.g., R received signals) to a set of modems  254  (e.g., R modems), shown as modems  254   a  through  254   r . For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem  254 . Each modem  254  may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem  254  may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from the modems  254 , may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE  120  to a data sink  260 , and may provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE  120  may be included in a housing  284 . 
     The network controller  130  may include a communication unit  294 , a controller/processor  290 , and a memory  292 . The network controller  130  may include, for example, one or more devices in a core network. The network controller  130  may communicate with the base station  110  via the communication unit  294 . 
     One or more antennas (e.g., antennas  234   a  through  234   t  and/or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of  FIG.  2   . 
     On the uplink, at the UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor  280 . The transmit processor  264  may generate reference symbols for one or more reference signals. The symbols from the transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by the modems  254  (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station  110 . In some examples, the modem  254  of the UE  120  may include a modulator and a demodulator. In some examples, the UE  120  includes a transceiver. The transceiver may include any combination of the antenna(s)  252 , the modem(s)  254 , the MIMO detector  256 , the receive processor  258 , the transmit processor  264 , and/or the TX MIMO processor  266 . The transceiver may be used by a processor (e.g., the controller/processor  280 ) and the memory  282  to perform aspects of any of the methods described herein (e.g., with reference to  FIGS.  5 - 11   ). 
     At the base station  110 , the uplink signals from UE  120  and/or other UEs may be received by the antennas  234 , processed by the modem  232  (e.g., a demodulator component, shown as DEMOD, of the modem  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 the UE  120 . The receive processor  238  may provide the decoded data to a data sink  239  and provide the decoded control information to the controller/processor  240 . The base station  110  may include a communication unit  244  and may communicate with the network controller  130  via the communication unit  244 . The base station  110  may include a scheduler  246  to schedule one or more UEs  120  for downlink and/or uplink communications. In some examples, the modem  232  of the base station  110  may include a modulator and a demodulator. In some examples, the base station  110  includes a transceiver. The transceiver may include any combination of the antenna(s)  234 , the modem(s)  232 , the MIMO detector  236 , the receive processor  238 , the transmit processor  220 , and/or the TX MIMO processor  230 . The transceiver may be used by a processor (e.g., the controller/processor  240 ) and the memory  242  to perform aspects of any of the methods described herein (e.g., with reference to  FIGS.  5 - 11   ). 
     The controller/processor  240  of the base station  110 , the controller/processor  280  of the UE  120 , and/or any other component(s) of  FIG.  2    may perform one or more techniques associated with using an integrated wake up signal (WUS) and BWP switching sequence, as described in more detail elsewhere herein. For example, the controller/processor  240  of the base station  110 , the controller/processor  280  of the 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. The memory  242  and the memory  282  may store data and program codes for the base station  110  and the UE  120 , respectively. In some examples, the memory  242  and/or the memory  282  may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station  110  and/or the UE  120 , may cause the one or more processors, the UE  120 , and/or the base station  110  to perform or direct operations of, for example, process  800  of  FIG.  8   , process  900  of  FIG.  9   , and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples. 
     In some aspects, a first mobile station (e.g., UE  120 ) includes means for selecting, by the first mobile station, a sequence that is to be used by a second mobile station to wake up and switch to a BWP indicated by the sequence, and/or means for transmitting, by the first mobile station, the sequence to the second mobile station. In some aspects, the means for the first mobile station to perform operations described herein may include, for example, one or more of communication manager  140 , antenna  252 , modem  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , TX MIMO processor  266 , controller/processor  280 , or memory  282 . 
     In some aspects, a second mobile station (e.g., UE  120 ) includes means for receiving, by the second mobile station from a first mobile station, a sequence that is to be used by the second mobile station to wake up and switch to a BWP indicated by the sequence, and/or means for switching, by the second mobile station, to the BWP after waking up in connection with receiving the sequence. In some aspects, the means for the second mobile station to perform operations described herein may include, for example, one or more of communication manager  140 , antenna  252 , modem  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , TX MIMO processor  266 , controller/processor  280 , or memory  282 . 
     While blocks in  FIG.  2    are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor  264 , the receive processor  258 , and/or the TX MIMO processor  266  may be performed by or under the control of the controller/processor  280 . 
     As indicated above,  FIG.  2    is provided 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 sidelink communications, in accordance with the present disclosure. 
     As shown in  FIG.  3   , a first UE  305 - 1  may communicate with a second UE  305 - 2  (and one or more other UEs  305 ) via one or more sidelink channels  310 . The UEs  305 - 1  and  305 - 2  may communicate using the one or more sidelink channels  310  for P2P communications, D2D communications, V2X communications (e.g., which may include V2V communications, V2I communications, and/or V2P communications) and/or mesh networking. In some aspects, the UEs  305  (e.g., UE  305 - 1  and/or UE  305 - 2 ) may correspond to one or more other UEs described elsewhere herein, such as UE  120 . In some aspects, the one or more sidelink channels  310  may use a PC5 interface and/or may operate in a high frequency band (e.g., the 5.9 GHz band). Additionally, or alternatively, the UEs  305  may synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols) using global navigation satellite system (GNSS) timing. 
     As further shown in  FIG.  3   , the one or more sidelink channels  310  may include a physical sidelink control channel (PSCCH)  315 , a physical sidelink shared channel (PSSCH)  320 , and/or a physical sidelink feedback channel (PSFCH)  325 . The PSCCH  315  may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and/or a physical uplink control channel (PUCCH) used for cellular communications with a base station  110  via an access link or an access channel. The PSSCH  320  may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PUSCH) used for cellular communications with a base station  110  via an access link or an access channel. For example, the PSCCH  315  may carry sidelink control information (SCI)  330 , which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, and/or spatial resources) where a transport block (TB)  335  may be carried on the PSSCH  320 . The TB  335  may include data. The PSFCH  325  may be used to communicate sidelink feedback  340 , such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK/NACK) information), transmit power control (TPC), and/or a scheduling request (SR). 
     Although shown on the PSCCH  315 , in some aspects, the SCI  330  may include multiple communications in different stages, such as a first stage SCI (SCI-1) and a second stage SCI (SCI-2). The SCI-1 may be transmitted on the PSCCH  315 . The SCI-2 may be transmitted on the PSSCH  320 . The SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and/or spatial resources) on the PSSCH  320 , information for decoding sidelink communications on the PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH demodulation reference signal (DMRS) pattern, an SCI format for the SCI-2, a beta offset for the SCI-2, a quantity of PSSCH DMRS ports, and/or a modulation and coding scheme (MCS). The SCI-2 may include information associated with data transmissions on the PSSCH  320 , such as a hybrid automatic repeat request (HARQ) process identifier (ID), a new data indicator (NDI), a source identifier, a destination identifier, and/or a channel state information (CSI) report trigger. 
     In some aspects, the one or more sidelink channels  310  may use resource pools. For example, a scheduling assignment (e.g., included in SCI  330 ) may be transmitted in sub-channels using specific resource blocks (RBs) across time. In some aspects, data transmissions (e.g., on the PSSCH  320 ) associated with a scheduling assignment may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmissions are not transmitted on adjacent RBs. 
     In some aspects, a UE  305  may operate using a sidelink transmission mode (e.g., Mode 1) where resource selection and/or scheduling is performed by a base station  110 . For example, the UE  305  may receive a grant (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as for configured grants) from the base station  110  for sidelink channel access and/or scheduling. In some aspects, a UE  305  may operate using a transmission mode (e.g., Mode 2) where resource selection and/or scheduling is performed by the UE  305  (e.g., rather than a base station  110 ). In some aspects, the UE  305  may perform resource selection and/or scheduling by sensing channel availability for transmissions. For example, the UE  305  may measure an RSSI parameter (e.g., a sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, may measure an RSRP parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, and/or may measure an RSRQ parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and may select a channel for transmission of a sidelink communication based at least in part on the measurement(s). 
     Additionally, or alternatively, the UE  305  may perform resource selection and/or scheduling using SCI  330  received in the PSCCH  315 , which may indicate occupied resources and/or channel parameters. Additionally, or alternatively, the UE  305  may perform resource selection and/or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE  305  can use for a particular set of subframes). 
     In the transmission mode where resource selection and/or scheduling is performed by a UE  305 , the UE  305  may generate sidelink grants, and may transmit the grants in SCI  330 . A sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission on the PSSCH  320  (e.g., for TBs  335 ), one or more subframes to be used for the upcoming sidelink transmission, and/or a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission. In some aspects, a UE  305  may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of a sidelink transmission. Additionally, or alternatively, the UE  305  may generate a sidelink grant for event-driven scheduling, such as for an on-demand sidelink message. 
     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 sidelink communications and access link communications, in accordance with the present disclosure. 
     As shown in  FIG.  4   , a transmitter (Tx)/receiver (Rx) UE  405  and an Rx/Tx UE  410  may communicate with one another via a sidelink, as described above in connection with  FIG.  3   . As further shown, in some sidelink modes, a base station  110  may communicate with the Tx/Rx UE  405  via a first access link. Additionally, or alternatively, in some sidelink modes, the base station  110  may communicate with the Rx/Tx UE  410  via a second access link. The Tx/Rx UE  405  and/or the Rx/Tx UE  410  may correspond to one or more UEs described elsewhere herein, such as the UE  120  of  FIG.  1   . Thus, a direct link between UEs  120  (e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between a base station  110  and a UE  120  (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be transmitted via the sidelink, and access link communications may be transmitted via the access link. An access link communication may be either a downlink communication (from a base station  110  to a UE  120 ) or an uplink communication (from a UE  120  to a base station  110 ). 
     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 BWPs, in accordance with the present disclosure. 
     A UE may switch to a BWP that is only part of a frequency band. The UE may save power by using part of the frequency band rather than the whole band. The UE may switch to different BWPs to account for data variations. For example, BWP 2 in example  500  may be used instead of the overall frequency for the carrier. However, if there is less data to be communicated, the UE may switch to BWP 1. The UE may use BWP 1 or BWP 2 as a default BWP for receiving synchronization signal blocks (SSBs). 
     After an initial access by the UE, a base station (e.g., gNB) may cause the UE to switch from the default BWP to another BWP via radio resource control (RRC) switching or via downlink control information (DCI). However, using DCI to switch BWPs may be problematic if the UE fails to decode the DCI. This may make communications difficult thereafter. 
     There are options for BWP support. In one option, a BWP may be configured based on cell-specific parameters and/or UE-specific parameters. UE-specific parameters for BWP configuration may take into account a BWP switching capability of the UE and thus the gNB may be aware of the type of BWP switch that a UE can support before BWP switching is performed. BWP switching may be used in sidelink communications between a first UE and a second UE. 
     The first UE may enter an idle state to save power and wake up and enter a connected state periodically or when woken up with a WUS. For example, a second UE may wake up the first UE to transmit a low data rate application (e.g., impending collision indication) or a high data rate application (e.g., sensor sharing application). That is, the first UE may need to be woken up with a WUS signal, but the WUS signal does not indicate whether the first UE is to switch to a low data BWP or a high data BWP. To cause the first UE to switch to the appropriate BWP, the second UE has to transmit additional RRC signaling, which consumes time and signaling resources. 
     According to various aspects described herein, the second UE may transmit a message that both wakes up the first UE and switches the first UE to a BWP. The message may be a sequence, such as an integrated WUS and BWP sequence. The sequence may indicate the BWP to which the first UE is to switch. The indicated BWP may be the BWP that is active when the first UE wakes up. Switching to the BWP may include the first UE waking up to a different BWP than the default BWP or waking up to the default BWP if the indicated BWP is also the default BWP. The sequence may be used for unicast or groupcast communications and for connectionless or connected UEs. As a result, the first UE may save time and conserve signaling resources. 
     As indicated above,  FIG.  5    is provided as an example. Other examples may differ from what is described with regard to  FIG.  5   . 
       FIG.  6    is a diagram illustrating an example  600  associated with using an integrated WUS and BWP switch sequence  602 , in accordance with the present disclosure. As shown in  FIG.  6   , a first UE  610  (e.g., a UE  120 , UE  405 ) and a second UE  620  (e.g., a UE  120 , UE  410 ) may communicate with one another. UE  620  may be in an idle state. 
     As shown by reference number  630 , UE  610  may select the integrated sequence  602 , which is a sequence (coded indication) that integrates a WUS and a BWP switch into a single message. UE  610  may select the BWP based at least in part on an application used by UE  620 , traffic conditions, UE type, UE status, or sidelink channel conditions. UE  610  may select the integrated sequence  602  associated with the selected BWP from among multiple sequences for multiple BWPs. UE  610  may also select the integrated sequence  602  by generating the integrated sequence  602  for the selected BWP and to include the WUS. As shown by reference number  635 , UE  610  may transmit the integrated sequence  602  to UE  620 . 
     As shown by reference number  640 , UE  620  may wake up after receiving the integrated sequence  602  and switch to the BWP indicated by the integrated sequence  602 . In some aspects, the indicated BWP may be activated before or when UE  620   wakes up. Alternatively, UE  620  may switch to the indicated BWP after waking up. This may include waiting for a delay. For example, for unicast sidelink communications, UE  610  may transmit the integrated sequence  602  to UE  620  based at least in part on a unique sequence or resource. The integrated sequence  602  may be a preconfigured first wake up sequence that indicates that UE  620  is to wake up and switch to BWP 1 from its currently used BWP 0 after a T slot delay (e.g., offset  642  in example  600 ). The integrated sequence  602  may be a preconfigured second wake up sequence that indicates that UE  620  is to wake up and switch to BWP 2 from current BWP 0 after a T 1  slot delay. The integrated sequence  602  may be a first wake up sequence at a preconfigured first resource (e.g., symbol or physical resource block) that indicates that UE  620  is to wake up and switch to BWP 3 from its current BWP 0 after a T 1  slot delay. 
     In some aspects, the integrated sequence  602  may indicate that UE  620  is to wake up and perform the BWP switch only for a time duration  644  of T 3  slots from the offset  642  of T 1  slots (slot offset or offset time period with respect to the slot when the integrated sequence  602  is received), and thereafter switch back to the previous BWP (e.g., default BWP), as shown by reference number  645 . The offset  642  from which the BWP is active and the time duration  644  of the BWP switch may be based at least in part on the sequence or resource in which the integrated sequence  602  is transmitted. For example, as shown in example  600 , the integrated sequence  602  may indicate BWP 1, the offset  642  after reception of the integrated sequence  602  to switch to BWP 1 (activate BWP 1), and the time duration  644  during which BWP 1 is active before UE  620  switches back to the previous BWP. UE  620  may use a timer for the time duration  644  (switch duration). UE  610  switches BWPs as well, to operate in the same BWP as UE  620 . 
     In some aspects, UE  620  may provide feedback to UE  610  on an assigned feedback resource. UE  620  may provide successful feedback when UE  620  wakes up. If UE  610  does not receive successful feedback (or receives negative feedback), such as during the offset  642 , UE  610  may not switch to the BWP indicated by the integrated sequence  602 . UE  610  may transmit a message to UE  620 , informing UE  620  that there is to be no BWP switch, and UE  610  and UE  620  may continue operating in a current BWP (e.g., default BWP). 
     In an example for groupcast sidelink communications, UE  610  may select the integrated sequence  602  from among a set of group integrated sequences. UE  610  may transmit the integrated sequence  602  to a group of UEs, which may include UE  620  and UE  650 . UE  620  may wake up and determine that the integrated sequence  602  is group-specific and not UE-specific. The integrated sequence  602  may include a group identifier (ID) or a destination ID that is common to UE  620  and UE  650 . 
     In some aspects, if any UE in the group of UEs is not able to accommodate a requested BWP switch, that UE may transmit negative feedback (e.g., NACK) to UE  610 . UE  610  may then transmit a message to the group that cancels the BWP switch (fall back to current or default BWP). In this scenario, the integrated sequence  602  may act as a WUS but not an indication of a BWP switch. UE  610  (or a gNB or an RSU) may be aware of BWP switch capabilities of UE  620  and UE  650 , and may provide a group integrated sequence that ensures that all UEs in the group, such as UE  620  and UE  650 , have the appropriate BWP switch capability. 
     As indicated above,  FIG.  6    is provided as an example. Other examples may differ from what is described with regard to  FIG.  6   . 
       FIG.  7    is a diagram illustrating an example  700  of an application associated with an integrated sequence, in accordance with the present disclosure. Example  700  shows applications  710 ,  720 , and  730 . 
     In some aspects, BWPs may be mapped to applications of the UE  620  and/or to Quality of Services (QoSs) of the applications. For example, a V2X layer  740  (e.g., in UE  610  or an RSU) may determine an application ID of a message to be transmitted and a possible receiver (e.g., UE  620 ) of the message. This determination may be a trigger for the integrated sequence  602 . If the receiver is determined to be in an idle state (e.g., via information obtained from a prior discontinuous reception (DRX) cycle exchange) and needs to be woken up, then the V2X layer  740  may determine a QoS requirement (e.g., bandwidth requirement) for transmitting the application, together with the required wake-up configuration (e.g., group-specific or UE-specific) for the integrated sequence  602 . The V2X layer  740  may use a mapping  750  between the QoS requirement (e.g., bandwidth requirement) and the appropriate BWP to identify the BWP for the integrated sequence  602 . The V2X layer  740  may indicate the appropriate BWP to the medium access control (MAC) and physical (PHY) layers for selection of the corresponding integrated sequence  602 . The integrated sequence  602  may be transmitted to wake up the receiver in the appropriate BWP, to satisfy the QoS requirement for the application with reduced latency. 
     As indicated above,  FIG.  7    is provided as an example. Other examples may differ from what is described with regard to  FIG.  7   . 
       FIG.  8    is a diagram illustrating an example process  800  performed, for example, by a first mobile station, in accordance with the present disclosure. Example process  800  is an example where the first mobile station (e.g., a UE  120 , UE  610 ) performs operations associated with an integrated WUS and BWP switch sequence. 
     As shown in  FIG.  8   , in some aspects, process  800  may include selecting a sequence that is to be used by a second mobile station to wake up and switch to a BWP indicated by the sequence (block  810 ). For example, the first mobile station (e.g., using communication manager  140  and/or selection component  1008  depicted in  FIG.  10   ) may select a sequence that is to be used by a second mobile station to wake up and switch to a BWP indicated by the sequence, as described above. 
     As further shown in  FIG.  8   , in some aspects, process  800  may include transmitting the sequence to the second mobile station (block  820 ). For example, the first mobile station (e.g., using communication manager  140  and/or transmission component  1004  depicted in  FIG.  10   ) may transmit the sequence to the second mobile station, 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, the sequence indicates that the BWP is a first BWP and that the second mobile station is to wake up and switch to the first BWP after an offset. 
     In a second aspect, alone or in combination with the first aspect, the sequence indicates that the second mobile station is to wake up at a first resource. 
     In a third aspect, alone or in combination with one or more of the first and second aspects, the sequence indicates that the second mobile station is to switch to the BWP for a time duration and return to a previous BWP after the time duration. 
     In a fourth aspect, alone or in combination with one or more of the first through third aspects, the sequence indicates an offset from which the time duration starts. 
     In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, process  800  includes switching, by the first mobile station, to the BWP associated with the sequence. 
     In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, process  800  includes continuing, by the first mobile station, in a current BWP if feedback for the sequence is not received within an offset period after transmitting the sequence. 
     In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, selecting the sequence includes selecting the sequence from within a set of group integrated sequences, and transmitting the sequence includes transmitting the sequence to a group of mobile stations that includes the second mobile station. 
     In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, process  800  includes transmitting, by the first mobile station to the group of mobile stations, a message to cancel switching to the BWP if a NACK is received from at least one mobile station of the group of mobile stations. 
     In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, transmitting the sequence to the group of mobile stations includes transmitting the sequence to the group of mobile stations based at least in part on information that indicates that each of the mobile stations in the group of mobile stations has a capability to switch to the BWP. 
     In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, selecting the sequence includes selecting the sequence based at least in part on a trigger from an application.
