Abstract:
Methods, systems, and devices for wireless communications are described for adjusting transmit powers for concurrent uplink transmissions from a user equipment (UE) to multiple transmission reception points (TRPs), or dropping one or more uplink transmissions to one or more TRPs, based on one or more parameters. A UE may identify that a combined transmission power for concurrent uplink transmissions exceeds a power threshold of the UE, and may adjust a power for one or more of the concurrent uplink transmissions, or drop one or more of the uplink transmissions based on such an identification. If a difference in transmit powers of the concurrent uplink transmissions exceeds a power difference threshold, the UE may drop one or more lower priority transmissions. The UE may multiplex at least a portion of a dropped transmission with another uplink transmission that will be transmitted, such as by rate-matching or puncturing.
