1. A baseband processor configured to perform operations comprising:
receiving a first system information block (SIB1) indicating that a base station supports (UE)-Initiated channel occupancy time (COT);
receiving, in radio resource control (RRC) signaling dedicated to a UE, a plurality of UE-Initiated COT frame based equipment (FBE) channel sensing configurations, wherein different UE-Initiated COT FBE channel sensing configurations of the plurality are associated with different listen-before-talk (LBT) bandwidths;
in response to uplink data for transmission,
selecting, based on a bandwidth in which the UE performs LBT, one of the received plurality of UE-Initiated COT FBE channel sensing configurations;
controlling a transceiver to perform UE-Initiated COT FBE channel sensing based on the selected UE-Initiated COT FBE channel sensing configuration to acquire a COT; and
controlling the transceiver to transmit the uplink data during the COT.
