发明名称 METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM
摘要 Disclosed are a method and an apparatus for transmitting a reference signal. A method for receiving a reference signal may comprise the steps of: a subframe including a plurality of resource blocks (RB) and a plurality of OFDM symbols receiving a synchronization signal; and determining the number of RBs which are included in one precoding resource block group (PRB), on the basis of the size of a total system bandwidth, wherein the RBs included in the PRG may include information to which identical precoding has been applied. The synchronization signal is received by six core RBs from the plurality of RBs, and the reference signal can be received by at least one OFDM symbol from the plurality of OFDM symbols, excluding the first and second OFDM symbols, through a plurality of PRGs including the six core RBs. As a result, a channel can be accurately estimated on the basis of the reference signal.
