Method and apparatus for performing coordinated multi-point transmission and reception in wireless communication system
First Claim
1. An operating method of a base station for a Coordinated Multi-Point (CoMP) transmission in a wireless communication system, the method comprising:
- receiving, from a terminal, a sounding reference signal (SRS) generated by using a cell identifier (ID);
measuring, if the cell ID is identical to a cell ID for the CoMP transmission, a channel quality between the base station and the terminal based on the SRS; and
transmitting, to the terminal, if the channel quality is greater than a designated value, a notification message informing that the base station participates in the CoMP transmission for the terminal.

Abstract
A method and an apparatus for performing a Coordinated Multi-Point (CoMP) transmission in a wireless communication system are provided. An operating method of a base station for the CoMP transmission in a wireless communication system includes performing a cell clustering for CoMP transmission of a terminal, receiving a reference signal from the terminal, determining cell IDentifier (ID) information of the terminal, when the terminal uses a cell ID for the CoMP transmission, comparing a Channel Quality Indicator (CQI) value of the reference signal with a threshold, and when the CQI value of the reference signal is greater than or equal to the threshold, participating in the CoMP transmission of the terminal.
