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:
- performing a cell clustering for CoMP transmission of a terminal;
receiving a reference signal from the terminal and determining cell IDentifier (ID) information of the terminal;
comparing a Channel Quality Indicator (CQI) value of the reference signal with a threshold, when the terminal uses a cell ID for the CoMP transmission; and
participating in the CoMP transmission of the terminal, when the CQI value of the reference signal is greater than or equal to the threshold.

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.

10. A system for performing a Coordinated Multi-Point (CoMP) transmission in a wireless communication system, the system comprising:
-
a plurality of base stations for forming a cell clustering group and for participating in the CoMP transmission of a terminal; and the terminal for transmitting the CoMP transmission to the cell clustering group, wherein each of the base stations determines cell IDentifier (ID) information of the terminal by receiving a reference signal from the corresponding terminal, compares a Channel Quality Indicator (CQI) value of the reference signal with a threshold when the corresponding terminal uses a cell ID for the CoMP transmission, and participates in the CoMP transmission of the terminal when the CQI value of the reference signal is greater than or equal to the threshold, and wherein the terminal determines whether to support the CoMP transmission, and when supporting the CoMP transmission, transmits a reference signal to the plurality of base stations using a cell ID for the CoMP transmission. - View Dependent Claims (11, 12, 13, 14, 15)
