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: 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: 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: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure sidelink channel conditions for a group of UEs and transmit a report (e.g., a channel state information (CSI) report) to a base station indicating the sidelink channel conditions. The base station may transmit control information (e.g., group-common downlink control information (GC-DCI)) to the group of UEs triggering the UEs to transmit sidelink reference signals (e.g., CSI reference signals (CSI-RS)) on the sidelink channels so that the UE can measure the sidelink channel conditions and transmit the report. Based on the report, the base station may transmit control information (e.g., a downlink control information (DCI) message) scheduling sidelink communications for the group of UEs. In some examples, the UE may act as a relay node for the group of UEs, and forward control information to the group of UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that multiple physical uplink channels scheduled for the UE overlap. The multiple physical uplink channels may include a first physical uplink channel and a second physical uplink channel that are associated with different priority levels. The UE may transmit at least one of the first physical uplink channel or the second physical uplink channel according to a prioritization or a multiplexing of the first physical uplink channel and the second physical uplink channel. The prioritization or the multiplexing is based at least in part on whether the UE is enabled to perform simultaneous physical uplink control channel and physical uplink shared channel transmissions. Numerous other aspects are provided.
