Method and apparatus for transmitting reference signal

摘要

Disclosed are a method and an apparatus for transmitting a reference signal. The method for transmitting the reference signal comprises the step of: transmitting a secondary synchronization signal (SSS) and a primary synchronization signal (PSS) from a subframe including an N (natural number wherein N>1) number of resource blocks (RB) and a plurality of orthogonal frequency division multiplexing (OFDM) symbols; and transmitting from the subframe the reference signal which is generated on the basis of a cell identifier, wherein the reference signal can be transmitted from an M (natural number wherein K<=M

1. A method for transmitting a reference signal, the method comprising:
transmitting a secondary synchronization signal (SSS) and a primary synchronization signal (PSS) in a subframe including N resource blocks (RBs) and a plurality of orthogonal frequency division multiplexing (OFDM) symbols; and transmitting a reference signal created based on a cell identifier in the subframe, wherein the PSS is transmitted in K contiguous RBs selected from a plurality of RBs in a sixth OFDM symbol of the subframe, wherein the SSS is transmitted in K contiguous RBs selected from the plurality of RBs in a seventh OFDM symbol of the subframe, wherein the reference signal is transmitted in M RBs including K RBs in the remaining OFDM symbols except for the sixth OFDM symbol and the seventh OFDM symbol, wherein N is a natural number greater than 1, wherein K is a natural number less than N, wherein M is a natural number greater than or equal to K and less than N, wherein M is an even number when N is an even number, wherein M is an odd number when N is an odd number, and wherein the reference signal is transmitted through an additional frequency bandwidth when a frequency band in which the reference signal is transmitted and a boundary of the RBs in which the reference signal is transmitted do not coincide with each other.
