Abstract:
A method of decoding a backhaul downlink signal of a relay node (RN). A higher layer signal indicating a maximum transmission rank is received from a base station (BS). Control information is received through a relay control channel from the BS. The control information is demodulated and 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. The control information is demodulated based on URSs transmitted by the BS on one fixed antenna port n, where n is a natural number.
