Method and apparatus for transmitting and receiving feedback information for inter-cell cooperative transmission in wireless communication cellular system

A method for receiving feedback information for collaborative transmission in a cellular radio communication system, the method comprising:

• receiving feedback information including cell indicators for discriminating between at least two preferred collaborative cells and at least one non-preferred collaborative cell, precoding matrix indicators for the at least two preferred collaborative cells, and channel quality indicators, via one of a control channel and a data channel;
• and
• scheduling the collaborative transmission based on the feedback information,
• wherein the feedback information is transmitted in a transmission format having a fixed size regardless of a number of collaborative cells.

An apparatus for transmitting feedback information for collaborative transmission in a cellular radio communication system, the apparatus comprising:

• a receiver configured to receive a first Radio Frequency (RF) signal;
• a transmitter configured to transmit a second RF signal;
• and
• a controller configured to:
• control the receiver to receive, from a base station, the first RF signal including collaborative cell information indicating at least three collaborative cells,
• determine at least two preferred collaborative cells among the at least three collaborative cells,
• generate feedback information including cell indicators for discriminating between the at least two preferred collaborative cells and at least one non-preferred collaborative cell, precoding matrix indicators for the at least two preferred collaborative cells, and channel quality indicators, and
• control the transceiver to transmit the second RF signal including the feedback information via one of a control channel and a data channel,
• wherein the feedback information is transmitted in a transmission format having a fixed size regardless of a number of collaborative cells.
