Method and apparatus for transmitting and receiving reference signal in wireless communication system

摘要

Methods and apparatus are provided for transmitting processing reference signals in a mobile communication system. A base station determines a reference signal pattern comprising at least one resource element, generates a bitmap indicator indicating whether zero transmission power is assigned to the at least one resource element of the reference signal pattern, and transmits the reference signal pattern and the bitmap indicator to a terminal. The terminal receives the reference signal pattern and the bitmap indicator, and processes a reference signal extracted according to the reference signal pattern and the bitmap indicator.

1. A method for transmitting at least one reference signal of a base station in a mobile communication system, comprising the steps of:
determining, at the base station, a non-zero transmission power reference signal configuration among a first plurality of reference signal configurations, wherein the non-zero transmission power reference signal configuration comprises at least one resource element; generating, at the base station, a bitmap indicator indicating a zero transmission power reference signal configuration among a second plurality of reference signal configurations; and transmitting information for the non-zero transmission power reference signal configuration and the bitmap indicator from the base station to a terminal.
