  • BACKHAUL DOWNLINK SIGNAL DECODING METHOD OF RELAY STATION AND RELAY STATION USING SAME
    Publication number: 20160248614
    Abstract: A method of decoding a backhaul downlink signal is presented. A relay node (RN) receives a higher layer signal indicating a maximum transmission rank from a base station (BS), receives control information containing a resource allocation for downlink data through a relay control channel from the BS, demodulates the control information, and receives the downlink data through a data channel based on the control information. The control information is mapped to resource elements (REs) which do not overlap with user equipment-specific reference signal (URS) REs in a control region which is used for the relay control channel transmission of the BS. The URS REs are reserved REs for URSs according to the maximum transmission rank.
