METHOD AND APPARATUS OF TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM INCLUDING RELAY NODE

摘要

PURPOSE: A method for transmitting a reference signal in a wireless communication system including a relay station and a device thereof are provided to demodulate RPDCCH(Relay-Physical Downlink Control Channel) by using a CRS(Cell-specific Reference Signal) of a 3GPP(3rd Generation Partnership Project) LTE Rel-8 system and a DMRS(Demodulation Reference Signal) of a LTE(Long-Term Evolution)-A(Advanced) system. CONSTITUTION: A base station generate a plurality of reference signals about an antenna ports(S100). According to a predetermined reference signal pattern, the base station maps a plurality of reference signal to at least one RBs(Resource Blocks)(S110). The base station transmits at least one resource block to a RS(Relay Station)(S120). When the plurality of reference signal is mapped to one resource block, a CRS(Cell-specific Reference Signal) of a LTE(Long-Term Evolution) Rel-8 system is used.
