1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a medium access control (MAC)-layer message indicating a set of mappings between a set of pathloss reference signal (RS) identifiers and a set of physical uplink shared channel (PUSCH) power control identifiers, wherein the set of PUSCH power control identifiers is included in at least two adjacent octets of the MAC-layer message indicating the set of mappings between the set of pathloss RS identifiers and the set of PUSCH power control identifiers;
receiving downlink control information (DCI) activating a mapping of the set of mappings, wherein a resource indicator field of the DCI indicates a value associated with the mapping; and
performing a pathloss measurement using a pathloss RS identified by the activated mapping.
