Method for sharing radio resource information in multi-cell wireless communication system and apparatus for same
The present invention relates to a method and an apparatus for reporting channel state information of user equipment in a multi-cell wireless communication system. More particularly, the present invention comprises the steps of: receiving from a serving cell information on interference measurement resources (IMR) linked to at least one channel state information process (CSI process) and at least one item of CSI measurement information with respect to a plurality of radio resource sets having different interference characteristics; and reporting channel state information with respect to a specific radio resource set according to at least one item of information on the IMR and the at least one item of CSI measurement information, wherein the radio resource sets are defined so that uplink-downlink status changes depending on a system load state, and are linked to different channel state estimation processes.
