1. A method comprising:
transmitting, by a user equipment (UE), a configured-grant uplink control information (CG-UCI) to a base station during a channel occupancy time (COT) initiated by the UE in a shared spectrum, the CG-UCI comprising COT sharing information, the COT sharing information includes an index value referencing to a COT sharing combination of:
an indication of an offset to a beginning of a downlink transmission opportunity during the COT, the downlink transmission opportunity being dynamically determined by the UE;
an indication of a duration of the downlink transmission opportunity during the COT; and
an indication of a channel access priority class (CAPC) value; and
receiving, by the UE, a downlink transmission from the base station within the downlink transmission opportunity and in accordance with the COT sharing information,
wherein the COT sharing combination is one of a plurality of COT sharing combinations configurable for the UE,
wherein the index value indicates a row index of a row of a table of the plurality of COT sharing combinations, the row indicates the COT sharing combination, and at least one row of the table of the plurality of COT sharing combinations indicates that COT sharing is not available, and
wherein the table is configured via higher layer signaling.
