Title:
METHOD FOR PROCESSING CHANNEL STATE INFORMATION REFERENCE SIGNAL (CSI-RS) IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2015164326
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a CSI-RS transmission method efficiently using radio resources of eNBs while UE effectively perform channel measurement in an LTE-A system.SOLUTION: An embodiment of the present invention defines a plurality of CSI-RS patterns, assigns them to individual cells, uses the CSI-RSs alternately per Physical Resource Block (PRB) so as to utilize the transmission power of all antenna ports for transmitting CSI-RSs, transmits Coordinated Multi Point (CoMP) CSI-RSs and non-CoMP CSI-RSs separately, and mutes data in sections corresponding to the patterns in association with the CSI-RS pattern of adjacent cells.
