METHOD FOR COOPERATIVE SIGNAL TRANSMITTING IN MULTI-CELL COOPERATIVE COMMUNICATION SYSTEM

WIPO Patent Application WO/2013/191444

A1

The present invention relates to a method for a base station and a user cooperatively selecting a cell for receiving service and transmitting a signal in a cooperative multi-point (CoMP) environment, in which multiple cells cooperatively service the user. The present invention can achieve enhanced frequency efficiency when cooperative signal-transmitting by selecting the cell for receiving service from service candidate cells, depending on a channel status of the user, while considering channel quantization error, and can reduce multi-user scheduling complexity while reducing the amount of channel information feedback for multi-cell cooperative transmission.
