Abstract:
A method for transmitting feedback information for cooperative transmission in a wireless communication cellular system comprises: receiving information on cells that can be cooperatively transmitted from a base station; determining cells that prefer the cooperative transmission among the cells that can be cooperatively transmitted; generating feedback information, which includes a preference cell indicator representing preferred cells and non-preferred cells for the cooperative transmission among the cells that can be cooperatively transmitted, precoding matrix information for the respective cell that can be cooperatively transmitted, phase information representing a phase correction value of each of the preferred cells for the cooperative transmission, and a channel quality indicator; and transmitting the feedback information through a control channel or a data channel. Accordingly, the present invention provides a method and apparatus for transmitting and receiving a report of implicative feedback information on code books that can be designed for the gain improvement of a high-level inter-cell cooperative transmission.
