FEEDBACK METHOD AND APPARATUS FOR COOPERATIVE COMMUNICATION SYSTEM |
摘要 |
A feedback method and apparatus is provided for facilitating feedback in a Cooperative Multi-Point (CoMP) system in which multiple base stations cooperate with each other for downlink transmission to a terminal. The feedback method of a terminal includes determining whether the terminal is operating in cooperative multi-point mode for receiving data from a plurality of cells; estimating, when the terminal is operating in cooperative multi-point mode, channels of the cells belonging to a measurement set based on channel status information reference signals for the cells; selecting at least one best cell based on a signal-to-interference plus noise ratio based on the estimated channels; and feeding back a cell index and channel information of the best cell. |
