METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL

摘要

Disclosed are a method and an apparatus for transmitting a reference signal. A method for receiving the reference signal may comprise the steps of: a subframe including a plurality of resource blocks (RB) and a plurality of orthogonal frequency division multiplexing (OFDM) symbols receiving a synchronization signal; and the subframe receiving the reference signal, wherein the synchronization signal comprises a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), the PSS is a signal which is received by a first OFDM symbol from the plurality of OFDM symbols, the SSS is a signal which is received by a second OFDM symbol from the plurality of OFDM symbols, and the reference signal can be received by at least one OFDM symbol from the plurality of OFDM symbols which exclude the first OFDM symbol and the second OFDM symbol. Based on the reference signal, a channel can be accurately estimated.

1. A method for receiving a reference signal, comprising:
receiving a synchronization signal in a subframe including a plurality of resource blocks (RBs) and a plurality of orthogonal frequency division multiplexing (OFDM) symbols; and receiving a reference signal in the subframe, wherein the synchronization signal includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), wherein the PSS is a signal received in a first OFDM symbol among the plurality of OFDM symbols, wherein the SSS is a signal received in a second OFDM symbol among the plurality of OFDM symbols, wherein a cell identifier is acquired based on the PSS and the SSS, wherein the synchronization signal is received in center 6 RBs among the plurality of RBs, and wherein the reference signal is received through the center 6 RBs in at least one OFDM symbol other than the first and second OFDM symbols among the plurality of OFDM symbols.
