Abstract
The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.
