Abstract: This disclosure provides systems, methods, and devices for wireless communication that support managing compression and compression indications of a low-priority (LP) uplink control information (UCI) message that is multiplexed with a high-priority (HP) UCI message in a wireless communication system. In particular, a user equipment (UE) determines a compression indication for the LP UCI message, encodes the compression indication jointly with the HP UCI payload, and separately encodes the LP UCI payload. The encoded LP UCI payload is multiplexed with the jointly-encoded compression indication and HP UCI payload in an uplink transmission to a base station. The compression indication includes information related to whether and how the LP UCI has been compressed. The base station decodes the compression indication and then decodes the LP UCI message based on the compression indication.
