Abstract
A Channel State Information (CSI) transmission/reception method and an apparatus for transmitting/receiving CSI efficiently in a Coordinated Multi-Point (CoMP) communication system are provided. The CSI transmission method of a terminal for receiving Joint Transmission (JT) from a first Transmission Point (TP) and a second TP includes receiving a first CSI Reference Signal (CSI-RS) corresponding to the first TP, receiving a second CSI-RS corresponding to the second TP, generating an aggregated CSI corresponding to the first and second CSI-RSs, and transmitting the aggregated CSI, wherein generating an aggregated CSI comprising creating the aggregated CSI with a transmission timing of the aggregated CSI. The CSI transmission/reception method and apparatus is capable of transmission CSI efficiently in the CoMP system.
