  • Patent number: 8830902
    Abstract: A method, system and device for wireless communication are provided by the present invention. The method includes that: from the ending of the Transmit-Receive Guard interval (TRG) to the beginning of the Receive-Transmit Guard interval (RTG), an evolved Node B (eNB) carries Common Reference Signals (CRSs) or Demodulated Reference Signals (DMRSs) on the carriers are used for transmitting data signals and/or control signals to a Relay Node (RN); the RN demodulates, according to the CRSs or the DMRSs, the signals transmitted by the eNB; the TRG is the guard interval of the transition, for the RN, from transmitting signals to receiving signals over the backhaul link, and the RTG is the guard interval of the transition, for the RN, from receiving signals to transmitting signals over the backhaul link. The application of the present invention enables the RN to receive the data signals and/or control signals transmitted by the eNB correctly.
