Abstract: A user equipment (UE) sends an indication supported combinations of sounding reference signal (SRS) resources, unsupported combinations of SRS resources, or compatible SRS resources to a base station. The base station selects one or more SRS resources for the UE from the SRS resources that are supported by the UE or are compatible for the UE. In some examples, the UE receives a configuration from the base station for multiple SRS resource sets. After configuring the UE with multiple SRS resource sets, the base station selects one of the SRS resources sets, and may indicate the selected SRS resource set to the UE. The UE transmits a physical uplink shared channel (PUSCH) to the base station using SRS resources from the selected SRS resource set.

Abstract: Techniques for signaling varied modulation and coding schemes for wireless communication are discussed. A method of wireless communication may comprise receiving, by a user equipment (UE), an indication to apply a modulation order cap to determine a first modulation and coding scheme for transmission of uplink control information different from a second modulation and coding scheme for transmission of data. The method may further comprise transmitting the uplink control information using the first modulation and coding scheme, wherein the first modulation and coding scheme is determined based, at least in part, on the received indication to apply the modulation order cap.

Abstract: Techniques for compensating timing advance for full duplex communications are disclosed. In an example, a user equipment (UE) may receive, from a base station, a timing advance value and a compensation factor. The UE may also determine a timing compensation amount indicating an amount of time to adjust an uplink (UL) transmission based on the timing advance value and the compensation factor. The UE may also transmit, to the base station, the UL transmission according to the timing compensation amount. Other features are also described.

Abstract: A method of wireless communication includes selecting, by a user equipment (UE), a first codepoint from a codebook based on control information to be transmitted to a base station. The codebook is associated with non-coherent transmissions from the UE to the base station. The method further includes generating, based on the first codepoint and a scrambling sequence that is associated with the UE, a second codepoint representing the control information. The method further includes transmitting the second codepoint by the UE to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for requesting inter-UE coordination messages for sidelink communications. An example method for wireless communications by a first user equipment (UE) generally includes sending a sidelink communication on a first set of one or more subchannels in a first slot of sidelink resource pool, performing channel sensing on a second set of one or more subchannels in the first slot, and selecting one or more resources for a subsequent sidelink communication in at least a second slot of the sidelink resource pool on the channel sensing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a demodulation reference signal (DMRS) configuration for an uplink message that may indicate for the UE to refrain from including DMRS in at least a first portion of the uplink message based on the DMRS configuration. The UE may encode the uplink message without the DMRS in at least the first portion of the uplink message in accordance with the DMRS configuration. The UE may transmit the uplink message based on encoding the uplink message, and a network entity may receive and decode the uplink message. In some examples, the network entity may receive signaling that includes a set of uplink messages from different UEs. As such, the network entity may decode each, using a respective Reed-Muller (RM) code in accordance with a multi-user decoding algorithm.

Abstract: A sidelink device switches from a first bandwidth part (BWP) for sidelink communication to a second BWP for the sidelink communication and suspends, releases, or continues to use one or more reserved resources in the first BWP based on the switch from the first BWP to the second BWP for the sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a downlink transmission from a network device, the downlink transmission comprising a set of parity bits. The UE may determine, based at least in part on the monitoring, a number of parity checks of the set of parity bits that either failed a parity check procedure or satisfied the parity check procedure. The UE may identify, based at least in part on the monitoring and the number of parity checks, a feedback status indicator for the downlink transmission. The UE may transmit a feedback message that includes the feedback status indicator and additional information based at least in part on the number of parity checks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE in a sidelink communication with the first UE, an indication to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP. The UE may selectively switch from utilizing the first SL-BWP to utilizing the second SL-BWP based at least in part on receiving a positive acknowledgment message from the second UE. Numerous other aspects are provided.
