Method and apparatus for transmitting reference signal in multiple antenna system

摘要

A method and an apparatus for transmitting a reference signal in a multiple antenna system are provided. The method includes transmitting a first reference signal based on a first sequence through a first antenna group, and transmitting a second reference signal based on a second sequence through a second antenna group, wherein the first reference signal and the second reference signal are transmitted through a same radio resource.

1. A method for transmitting a signal in a multiple antenna system, the method performed by a transmitter and comprising:
transmitting a first reference signal for a first antenna using a first sequence; and transmitting a second reference signal for a second antenna using a second sequence, wherein the first sequence comprises a first portion and a second portion, the first portion is multiplied by a first phase shift value, the second portion is multiplied by a second phase shift value, and a phase offset exists between the first and second phase shift values, wherein the first portion of the first reference signal and the second portion of the first reference signal are transmitted on a same orthogonal frequency division multiplexing (OFDM) symbol, wherein the first reference signal and the second reference signal are transmitted via same resource elements (REs).
