Abstract:
1. A method for transmitting a downlink signal in a Frequency Division (FD) type relay node (RN), the method comprising: transmitting, by the RN, a downlink control channel specific to the RN (“RN DL control channel”) in a first subband of a control region of a downlink subframe, the control region being divided into the first subband for the RN DL control channel and a second subband for a downlink control channel specific to an eNB (“eNB DL control channel”), the RN DL control channel being simultaneously transmitted with the eNB DL control channel; and transmitting, by the RN, a downlink shared channel including data of the RN (“RN DL shared channel”) in a first subband of a data region of the downlink subframe, the data region being divided into the first subband for the RN DL shared channel and a second subband for a downlink shared channel including data of the eNB (“eNB DL shared channel”), the RN DL shared channel being simultaneously transmitted with the eNB DL shared channel, wherein bandwidths of the RN DL shared channel and the eNB DL shared channel are variable in each subframe according to channel state, and wherein the method further comprises transmitting a reference signal (RS) dedicated to the RN in the first subband of the data region.
