1. An apparatus for communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive, from a network entity, a downlink control information (DCI) comprising a group transmission power control (TPC) message, the DCI indicating multiple TPCs including one or more TPCs associated with one or more secondary cells and a primary cell for the UE and one or more other UEs, wherein the one or more secondary cells comprises multiple secondary cells arranged in multiple blocks, wherein one of the multiple blocks in the DCI comprises a field to indicate one TPC of the one or more TPCs as being associated with one of the multiple secondary cells, wherein the DCI is a format 2_2 DCI that includes a set of appended zeros based on a payload size associated with a format 1_0 DCI, and wherein the format 2_2 DCI that comprises the group TPC message is based on a per bandwidth part (BWP) configuration;
identify a TPC, from the multiple TPCs, as to be applied to a target secondary cell of the multiple secondary cells or a target primary cell from the one or more TPCs; and
transmit, to the network entity, a physical uplink control channel (PUCCH) on the target secondary cell or the target primary cell based on the identified TPC from the one or more TPCs.
