A method and an apparatus for transmitting and receiving a feedback
signal in a cellular mobile communication
system is provided. The method of transmitting feedback in a Cooperative Multi-Point (CoMP)
system, includes receiving feedback set information including allocation information of a Channel Status Information Reference
Signal (CSI-RS) transmitted for estimating a channel of a
User Equipment (UE), receiving IDentification (ID) information for identifying a CoMP set including CSI-RS allocation information from a
cell operating in a CoMP mode, extracting the CoMP set using the ID information and a feedback set, detecting a first feedback mode and first feedback timing with a first CSI-RS not included in the CoMP set among CSI-
RSs included in the feedback set, and generating and transmitting feedback with respect to the first CSI-RS according to the detected first feedback mode and the first feedback timing.
