1. A method comprising:
receiving bandwidth information in a first bandwidth;
switching from the first bandwidth to a second bandwidth based on the bandwidth information;
switching to a third bandwidth different from the second bandwidth based on failure to perform a channel access procedure (CAP) in a resource for first uplink transmission of a data channel in the second bandwidth; and
performing uplink transmission of a control channel in the third bandwidth, wherein the control channel includes information for an index of the third bandwidth and information for a result of the channel access procedure in the second bandwidth, and
the third bandwidth is a preconfigured bandwidth.
