Method and apparatus for reporting channel state information for network cooperative communication

A method for receiving channel state information (CSI) performed by a base station in a wireless communication system, the method comprising:

• transmitting first information for generating CSI associated with a plurality of base stations and second information for reporting the CSI to a terminal when non-coherent joint transmission (NC-JT) by the plurality of base stations is configured for the terminal;
• transmitting at least one reference signal to the terminal based on the first information;
• and
• receiving the CSI generated based on the at least one reference signal and associated with the plurality of base stations from the terminal based on the second information.

A terminal for transmitting channel state information (CSI) in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• receive first information for generating CSI associated with a plurality of base stations and second information for reporting the CSI when non-coherent joint transmission (NC-JT) by the plurality of base stations is configured,
• receive at least one reference signal from each of the plurality of base stations based on the first information,
• generate the CSI associated with to the plurality of base stations based on the at least one reference signal, and
• transmit the CSI associated with the plurality of base stations based on the second information.
