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).

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: The apparatus of wireless communication may be a UE configured to activate a MAC-CE transmitted over an SL relay after waiting a time period by receiving an activation request for a command in association with a third UE in a first MAC-CE relayed from a second UE, transmitting, to the second UE, a second MAC-CE including an activation response to the third UE in response to the activation request, and activating the command after transmitting the activation response. The UE may wait a time period after transmitting the activation response before activating the command. The UE may receive an HARQ ACK from the third UE in response to the transmitted activation response or an HARQ ACK from the second UE in response to the transmitted activation response, and wait a time period after receiving the HARQ ACK before activating the command.
