METHOD FOR SIGNALING CONTROL INFORMATION FOR COORDINATED MULTIPOINT TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method for signaling control information for coordinated multipoint (CoMP) transmission in a wireless communication system. The control information signaling method for CoMP transmission is performed by a base station and comprises providing, through RRC signaling, a terminal with setup information on each CSI-RS resource of a CoMP measurement group which is set in the terminal; and selectively providing, through DCI, the terminal with control information which indicates mapping of the PDSCH resource element corresponding to terminal and at least either pseudo-same positionality information of CSI-RS or pseudo-same positionality information of DM-RS. Thus, control information signaling for coordinated multipoint transmission can be efficiently performed.
