METHOD AND APPARATUS FOR TRANSCEIVING CHANNEL STATUS INFORMATION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING COOPERATIVE TRANSMISSION

摘要

The present invention relates to a wireless communication system. A method for reporting CSI (Channel State Information) in a cooperative multi-point (CoMP) wireless communication system, the method performed by a user equipment (UE) and comprising receiving first resource configuration information for a CSI-RS (Channel-State Information-Reference Signal) and second resource configuration information for interference measurement; and calculating CSI using the first resource configuration information and the second resource configuration information, the CSI being for one or more base stations (BSs) among a plurality of BSs participating the COMP, wherein an interference measurement resource according to the second resource configuration information exists in a union of zero-power CSI-RS resources of each of the plurality of BSs.

1. A method for reporting CSI (Channel State Information) in a wireless communication system, the method performed by a user equipment (UE) and comprising:
configuring a first resource of a CSI-RS (Channel-State Information-Reference Signal) and a second resource of a CSI-IM (Channel State Information—interference measurement); and transmitting the CSI based on at least one of the first resource and the second resource, wherein the second resource of the CSI-IM exists in a union of two or more zero-power CSI-RS resources.
