1. A method of wireless communication, comprising:
receiving a configuration message from a serving base station, the configuration message including identification of COT sharing information to include in an uplink control message;
acquiring, by a user equipment (UE), a channel occupancy time (COT) in response to success detected of a listen before talk (LBT) procedure of the UE on a shared communication channel;
determining, by the UE, whether COT sharing is one of enabled or not enabled based on the identification of the COT sharing information in the configuration message;
identifying, by the UE, the COT sharing information for communication to the serving base station within the uplink control message, in response to determination that the COT sharing is enabled, the COT sharing information including each of:
a remaining COT duration from an end of one of a UE uplink transmission during the COT or a physical uplink shared channel (PUSCH) transmission containing the COT sharing information to an endpoint of the COT; and
an offset indication identifying the end of the UE uplink transmission; and
a channel access priority class (CAPC) used by the UE for acquisition of the COT; and
