摘要:
The present invention relates to a method for enabling a terminal to report channel state information in a wireless communication system for supporting coordinated multi point (CoMP) transmission. Specifically, the method for enabling the terminal to report the channel state information in the wireless communication system for supporting CoMP transmission includes the steps of: receiving a reference signal from a serving cell and one or more cooperated cells; forming the channel state information for the CoMP transmission on the basis of the reference signal; and reporting the channel state information through a physical uplink shared channel to the serving cell, wherein the channel state information includes channel quality indicator (CQI) information and precoding matrix index (PMI) information, and the CQI information includes a wideband CQI and a CQI for each selected sub-band of the CoMP transmission.
