A method for a user equipment (UE) which communicates with a base station is described. The method may comprise acquiring radio resource control (RRC) configuration information. The RRC configuration information may indicate a configuration of downlink control (DCI) format 2_0. The method may also comprise monitoring a physical downlink control channel (PDCCH) with the DCI format 2_0. The DCI format 2_0 may include a first information field. The first information field may indicate a remaining channel occupancy duration. The remaining channel occupancy duration may be expressed as the number of OFDM symbol(s) starting from a slot where the DCI format 2_0 is detected.
