Abstract:
A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.
