The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may measure one or more candidate bandwidths, each of the one or more candidate bandwidths corresponding to a candidate channel. The apparatus may also select an operating bandwidth of the one or more candidate bandwidths based on the measured one or more candidate bandwidths, the operating bandwidth corresponding to an operating channel. Additionally, the apparatus may adjust an energy detection threshold of a reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or an interference level of at least one signal.
