Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE may receive signaling configuring the UE with first and second sounding reference signal (SRS) resource sets. The UE may receive a first downlink control information (DCI) that schedules a first physical uplink shared channel (PUSCH) and indicates a first sounding reference signal (SRS) resource indicator (SRI) value, and a second DCI that schedules a second PUSCH and indicates a second SRI value. The UE may determine SRS resources indicated by the first and second SRI values based on an association between control resource set (CORESET) pool index values and the first and second SRS resource sets. The UE may transmit the first PUSCH indicated by the first SRI value and the second PUSCH indicated by the second SRI value, in accordance with the determination.

Abstract: A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.

Abstract: A UE of a wireless communication network first receives a modulation and coding scheme index IMCS for demodulating a physical layer data channel of the network. The UE then demodulates the physical layer data channel with a non-square quadrature amplitude modulation (NS-QAM) having a modulation order and code rate corresponding to a spectral efficiency (SPEFF) substantially equal to a SPEFF of a square QAM (S-QAM) SPEFF indicted by the IMCS, where the NS-QAM has an effective channel code rate no larger than the code rate for which the UE may skip decoding a transport block in an initial received transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

For example, a computing device may obtain an image, and may apply a process to the image to generate input image feature data and input image segmentation data. Further, the computing device may obtain reference image feature data and reference image classification data for a plurality of reference images. The computing device may generate reference image segmentation data based on the reference image feature data, the reference image classification data, and the input image feature data. The computing device may further blend the input image segmentation data and the reference image segmentation data to generate blended image segmentation data. The computing device may store the blended image segmentation data within a data repository. In some examples, the computing device provides the blended image segmentation data for display.

Abstract: In a wireless communication system, a peak to average power ratio (PAPR) may affect the efficiency of a power amplifier. To reduce a PAPR, a transmitting device may utilize a PAPR reduction precoding that changes a received signal without performance impact so the overall transmit PAPR is reduced. The transmitting device constructs a frequency domain (FD) response to the PAPR reduction precoding, estimates a channel to one or more receiving devices, and applies the PAPR reduction precoding to the estimated channel. The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive radio resource control (RRC) signaling that indicates to configure the UE with one or more formats for transmitting a radio link control (RLC) status report. The UE may transmit the RLC status report using an indicated format, of the one or more formats or an additional format for transmitting the RLC status report, wherein use of the indicated format is based at least in part on a physical layer indication or a medium access control (MAC) layer indication. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.

A UE may determine an application-layer capability of the UE in which the application-layer capability corresponds to a V2X application implemented on the UE, and transmit an announcement including an indication of the application-layer capability via a transceiver. A UE may also receive an announcement via a transceiver that includes an indication of an application-layer capability corresponding to a second UE in which the application-layer capability corresponds to a V2X application implemented on the second UE, and engage with the second UE via the V2X application.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QOS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enabling user equipment (UE) and a base station (BS) to communicate using a set of frequency resources in which a subset of frequency resources include a phase tracking reference signal (PTRS). In one aspect, the UE may measure the PTRS in the subset of frequency resources, and select a phase noise compensation that is used to demodulate a communication from the BS. The subset of frequency resources may be selected from the set frequency resources based on channel conditions of different subsets of frequency resources. The BS may provide an indication of the selected subset of frequency resources to the UE, such as in control information that schedules the communication from the BS.

Abstract: A UE may determine a number of antenna ports associated with a frequency band that includes one or more CCs. The determined number of antenna ports may be based on a plurality of UL Tx chains for the one or more CCs/frequency band. The UE may switch from a first UL Tx chain to a second UL Tx chain, at least one of which may be associated with the one or more CCs/frequency band. The number of antenna ports may correspond to a maximum number of antenna ports of an individual CC of the one or more CCs, or to a sum of antenna ports of the one or more CCs. For the latter, the number of antenna ports may be limited to an available number of UE antenna ports when the sum of antenna ports is greater than the available number of UE antenna ports.

Abstract: The apparatus receives a first PDU and a first CRC that is based on the first PDU. The first PDU is encrypted based on a first nonce. The apparatus decrypts the first PDU to obtain a first payload and a first cipher stream. The apparatus soft combines the decrypted first payload with a decrypted set of payloads. The set of payloads have been encrypted based on at least one nonce different than the first nonce. The apparatus generates a second CRC based on the soft combined decrypted payloads and based on the first cipher stream. The apparatus determines whether the generated second CRC for the soft combined decrypted payloads passes a CRC check against the first CRC.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), such as a UE associated with an extended reality (XR) device, may obtain frame data from one or more cameras associated with the UE. The UE may determine a path of a beam providing communication between the UE and a base station, determine a location of a base station in communication with the UE, or both, where the base station location may be relative to a location of the UE. The UE may identify, based on the frame data, the path of the beam, the base station location, the UE location, or a combination thereof, a physical blockage to the communication. The UE may perform beam management for the communication based on identifying the physical blockage, so as to mitigate the impact the physical blockage may have on the communications between the UE and the base station.

The network entity may be a location server or location management function. The PRS modification information may include a request to modify the PRS configuration and information indicating a start time, a stop time, a duration, or a combination thereof, associated with modifying the PRS configuration.
