Abstract: Disclosed are an apparatus and method in a wireless communication system, and a computer readable storage medium. The apparatus comprises a processing circuit, the processing circuit being configured to: instruct one or more second base stations to assess an idle channel for an unauthorized frequency band on the basis of position information of the one or more second base stations and position information of a user equipment such that the one or more second base stations control access to the unauthorized frequency band on the basis of information of the assessment result relating to the idle channel. According to at least one aspect of an embodiment of the present disclosure, accessing a channel on an unauthorized frequency band of, for example, 60 GHz on the basis of position information may improve the speed and reliability of channel access.
