A user equipment may receive a first physical uplink shared channel (PUSCH) configuration and a second PUSCH configuration. The user equipment may transmit a first uplink communication and a second uplink communication using different antenna panels, based at least in part on the first PUSCH configuration and the second PUSCH configuration.

Multiple uplink configurations for multiple antenna panel transmissions

An apparatus receives at least one scheduling grant scheduling transmission on a first data channel and further scheduling a second data channel. The apparatus reduces a transmit power for the transmission on the first data channel with a first beam when a radio frequency (RF) exposure event occurs. The apparatus increases, after the RF exposure event occurs, a transmit power for the transmission on the second data channel with a second beam. The apparatus transmits an RF exposure report associated with at least one of the first data channel or the first beam to the base station.

Power rebalancing in a maximum permissible exposure event

Determining, by a user equipment (UE) of a wireless communication system, that a physical uplink control channel (PUCCH) transmission of the UE carrying uplink control information (UCI) will collide upon transmission with another physical uplink shared channel (PUSCH) transmission of the UE. The UE then multiplexes, in response to the determining, the UCI on the PUSCH transmission based on one or more of the beam of the PUCCH transmission and the beam of the particular PUSCH transmission.

Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

The base station may identify the first beam or the second beam based on the overlap between the uplink control transmission and the uplink data transmission. The UE may transmit, and a base station may receive, at least a portion of the uplink control transmission and at least a portion of the uplink data transmission using the selected first beam or second beam.

In one aspect, the UE transmits an uplink request that indicates a trigger state for the UE. corresponding to at least one configured RS. The UE and the BS communicate the at least one RS corresponding to the trigger state for example, based on a grant from the BS or a time offset from the uplink request.
