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: The present invention provides an apparatus and a method in a wireless communication system, and a computer-readable storage medium. The apparatus comprises processing circuitry. The processing circuitry is configured to: determine, according to control information from a base station for simultaneously scheduling a user equipment (UE) and other UEs to perform multi-user multiple input multiple output (MU-MIMO) transmission, transmission-related configurations of other UEs, the control information comprising information indirectly indicating transmission-related configurations of other UEs; and decode, on the basis of the determined transmission-related configurations of other UEs, signals received from the base station, to obtain signals for the UE. According to the present invention, for the MU-MIMO transmission of a downlink data channel, by indirectly indicating to a target UE the transmission-related configurations of other UEs, “non-transparent” MU-MIMO transmission can be achieved without increasing signaling overhead, and the system throughput and reliability can be improved.
