摘要： Certain features relate to a remote antenna unit having a multi-stage isolation sub-system for isolating uplink and downlink signal paths. A multi-stage isolation sub-system in the remote antenna unit can include a first stage device that is configured to generate a cancellation signal for canceling unwanted downlink signals received at the uplink antenna. The isolation sub-system can also include a second stage device configured to generate a cancellation signal that attenuates residual noise and intermodulation products generated in the downlink path and received in the uplink path. The multi-stage isolation sub-system can combine the cancellation signals with signals received on the uplink path in order to cancel or attenuate downlink leakage signals and residual noise present on the uplink path.

摘要： 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.
