Abstract: Provided in the present disclosure are a device and method in a radio communication system, and a computer-readable storage medium. The device comprises a processing circuit configured to: decode a group common physical downlink control channel (group common PDCCH) of a user equipment group comprising a target user equipment so as to acquire control information related to multi-user multiple input multiple output (MU-MIMO) transmission of a control channel; and decode a user equipment-specific physical downlink control channel (UE-specific PDCCH) of the target user equipment on the basis of the control information so as to acquire specific transmission control information related to the target user equipment, where the UE-specific PDCCH of the target user equipment and UE-specific PDCCH of the other user equipment are stacked on a same transmission resource for transmission. MU-MIMO transmission with respect to a downlink control channel is effectively implemented, thus increasing resource utilization rate.
