1. A method, executed by a User Equipment (UE) operating in a Frame-Based Equipment (FBE) mode, comprising:
determining a starting time and a periodicity of a first Fixed Frame Period (FFP) of a first cell on an operating channel of an unlicensed band, wherein the first FFP is used for indicating a gNB-initiated channel occupancy time (COT);
determining a starting time and a periodicity of a second FFP for initiating an uplink transmission to the first cell, wherein the second FFP is used for a UE-initiated COT for the uplink transmission;
performing a Listen-Before-Talk (LBT) procedure on the operating channel of the unlicensed band; and
performing the uplink transmission to the first cell using a first uplink resource in the second FFP in response to the LBT procedure indicating that the operating channel of the unlicensed band is clear.
