Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment In (UE) may transmit, and a base station may receive, information indicating that the UE has a capability to support an uplink transmission configuration indication (TCI) state. The base station may transmit, and the UE may receive, downlink signaling identifying an uplink transmit beam based at least in part on the information indicating that the UE has the capability to support the uplink TCI state. The UE may transmit, and the base station may receive, uplink information using the uplink transmit beam identified in the downlink signaling. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that indicates a transmit precoding matrix indicator, that identifies a precoding matrix, and a set of demodulation reference signal (DMRS) antenna ports. A first association may be between a first set of antenna indices of the precoding matrix, that form a first transmission group, and a first code-division multiplexing (CDM) group of the set of DMRS antenna ports, and a second association may be between a second set of antenna indices of the precoding matrix, that form a second transmission group, and a second CDM group of the set of DMRS antenna ports. The UE may transmit an uplink transmission according to the first association and the second association. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a maximum permissible exposure (MPE) event associated with a beam, determine that a physical uplink control channel (PUCCH) resource for transmitting a scheduling request is unavailable based at least in part on the identification of the MPE event associated with the beam, and initiate, based at least in part on the determination that the PUCCH resource is unavailable, a physical random access channel (PRACH) procedure to transmit an uplink message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more beam metric values for one or more beams that are monitored by the UE, wherein the one or more beam metric values correspond to one or more of a beam power management maximum power reduction (P-MPR) metric, a beam uplink reference signal receive power (RSRP) metric, or a beam virtual power headroom metric; and transmit a report based at least in part on the one or more beam metric values. Numerous other aspects are provided.
