Disclosed are a UE supporting multiuser superposition, and a method and a device in a base station. In a first step, a UE separately receives K radio signal groups on K carriers, wherein each radio signal group comprises a first radio signal and a second radio signal, and K is a positive integer; and in a second step, an operation on a first wireless resource is determined on the basis that whether at least the second radio signal is correctly decoded, wherein time-frequency resources occupied by the first radio signal and time-frequency resources occupied by the second radio signal in the same radio signal group are entirely or partially overlapped. The present invention helps a base station determine an interference level caused by overlapped signals, and further, a proper policy is selected for retransmission. In addition, the present invention reduces overheads of wireless resources occupied by HARQ_ACK bits. |
