    Abstract: 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.

    Abstract: Methods and apparatuses are provided for transmitting channel information, by a UE. Information for at least one first type CSI-RS and information for at least one second type CSI-RS are identified. First channel information is generated based on a first type CSI-RS and a second type CSI-RS, among the at least one first type CSI-RS and the at least one second type CSI-RS. The first channel information is reported by PUCCH-based periodic channel information feedback. If a PDCCH including an indicator is received, second channel information is generated based on the first type CSI-RS and the second type CSI-RS. The second channel information is reported through a PUSCH. The indicator triggers a channel information report associated with the first type CSI-RS and the second type CSI-RS, among the at least one first type CSI-RS and the at least one second type CSI-RS.
