Abstract: The present invention relates to user equipment, an electronic device, a wireless communication method, and a storage medium. According to the present invention, the user equipment comprises a processing circuit, configured to: detect a physical downlink control channel (PDCCH) on a first bandwidth part of an unlicensed frequency band in a detection time of a discontinuous reception (DRX) period; and detect the PDCCH on a second bandwidth part of the unlicensed frequency band when the PDCCH is not detected on the first bandwidth part. By using the user equipment, the electronic device, the wireless communication method, and the storage medium in the present invention, a DRX mechanism of the user equipment operating on the unlicensed frequency band can be improved.

Abstract: A frequency allocation method and device for an unauthorized frequency band. The method includes: a controller acquires a business load status of plural macro base stations having similar coverage ranges and operated by different operators, and generates, based on the business load status, allocation information about an unauthorized frequency band, to mutually exclusively allocate the unauthorized frequency band to plural macro base stations; the macro base stations receive the allocation information about the unauthorized frequency band, to determine the unauthorized frequency band monopolized by the macro base stations from an unauthorized frequency band resource, and generate indicative information about the monopolized unauthorized frequency band; and a small base station receives the indicative information, detects state of the unauthorized frequency band monopolized by the macro base stations, and dynamically accesses, according to a detecting result, a specific unauthorized frequency band in the unauthorized frequency band monopolized by the macro base stations.
