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.
