1. A method performed by a user equipment (UE), comprising:
associating a first uplink power control parameter set with a first beam;
associating a second uplink power control parameter set with a second beam;
identifying a first transmit power based on received downlink control signaling or information corresponding to the first uplink power control parameter set;
identifying a second transmit power based on received downlink control signaling or information corresponding to the second uplink power control parameter set;
transmitting the first beam on one or more MIMO layers using the first transmit power; and
transmitting the second beam on one or more MIMO layers using the second transmit power.
