Abstract
A method of performing channel access on an unlicensed band by a user equipment, includes sensing a carrier of an unlicensed band for transmitting an uplink signal; and transmitting the uplink signal when power detected by sensing the carrier is less than an energy detection threshold that is configured by the user equipment, wherein the energy detection threshold is configured to be equal to or less than a maximum energy detection threshold determined by the user equipment, the maximum energy detection threshold is determined adaptively to a bandwidth of the carrier using a decibel value of a ratio between a reference bandwidth and the bandwidth of the carrier, and the maximum energy detection threshold is configured to be equal to or greater than a first power value which is a sum of a lower bound of the maximum energy detection threshold for the reference bandwidth and the decibel value.
