1. A terminal comprising:
a control unit configured to perform a channel access procedure in a frequency band above a predetermined frequency; and
a transmission unit configured to transmit a signal based on a result of the channel access procedure,
wherein the control unit performs the channel access procedure with a frequency bandwidth of a bandwidth part (BWP), determines an energy detection (ED) threshold value applied to the channel access procedure to be a value obtained by adding a predetermined value to a value that is proportional to the frequency bandwidth with which the channel access procedure is performed, and applies a maximum contention window size, which is less than a maximum contention window size that is applied to the channel access procedure that is performed with a frequency band below the predetermined frequency, to the channel access procedure.
