Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement configuration that is associated with a common measurement object or a common resource pool for at least two of cross-link interference (CLI) measurements, self-interference (SI) measurements, or wireless sensing measurements. The UE may perform, based at least in part on the measurement configuration, one or more measurements that include at least one of a CLI measurement, an SI measurement, or a wireless sensing measurement. The UE may transmit, based at least in part on the measurement configuration, a measurement report indicating at least one measurement of the one or more measurements. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a time domain resource allocation (TDRA), in a unit of a time domain resource block (RB) or in a unit of a time domain RB group, for a communication that is to use a time domain waveform. The unit of the time domain RB or the unit of the time domain RB group may be a sub-symbol unit. The UE may communicate with the base station, using the time domain waveform, based at least in part on the TDRA for the communication. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a base station to configure constraints on one or more transmission directions of a UE to reduce interference between UEs. In one aspect, a UE receives, from a base station, a grant for time-frequency resources for transmitting to a second UE, the grant including information indicating at least one of a first subset of beams of a set of beams for which the grant applies or a second subset of beams of the set of beams for which the grant applies with a constrained transmission power. The UE transmits, to the second UE, a PSSCH through at least one beam of the first subset of beams based on the received grant, or through at least one beam of the second subset of beams with the constrained transmission power based on the received grant.

Abstract: A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: Aspects relate to compression of messages in a wireless communication system. For messages, such as ACK/NACK feedback in a communication system, messages having an occurrence above or below a certain number of events (e.g., ACK/NACK events) or a probability of the occurrence may be compressed into a single message. By compressing the messages into a single message, the overhead used to transmit such messages may be reduced.

Abstract: This disclosure provides systems, methods and apparatuses for using acknowledgement or negative acknowledgement (ACK-NACK) bundling when reporting from a user equipment (UE) a bundled ACK-NACK for a plurality of physical downlink shared channels (PDSCHs) associated with a PDSCH grant. A counter downlink assignment indicator (DAT) and a total DAI may be used to track PDSCH grants that are received at the UE. The UE may detect missing PDSCHs and report ACK-NACKs for the missing PDSCHs based on the counter DAI and the total DAI. A base station (BS) may transmit the PDSCH grant associated with the plurality of PDSCHs to the UE. The BS may receive, from the UE, the bundled ACK-NACK for the plurality of PDSCHs associated with the PDSCH grant.

Abstract: Aspects described herein relate to providing demodulation reference signal (DMRS) transmissions for channel transmission repetitions. This can include defining DMRS patterns for channel transmission repetitions having a symbol length that is less than a threshold, dropping or deferring channel transmission repetitions that are mapped to a set of uplink symbols that are less than a threshold symbol length, and/or the like.

Abstract: In an aspect, a first UE transmits SL-PRS to a second UE based on a bandwidth associated with DL-PRS(s) from one or more gNBs to the second UE in association with a positioning procedure of the second UE. In other aspects, a network component (e.g., LMF UE, etc.) triggers transmission of a WLAN ranging signal from a first UE to a second UE (e.g., to supplement an NR-based positioning procedure).
