METHOD AND APPARATUS FOR HANDLING DOWNLINK REFERENCE SIGNAL INTERFERENCE TO PDSCH IN LONG TERM EVOLUTION COORDINATED MULTIPOINT TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To eliminate the interference arising due to reference signals from CoMP base stations.SOLUTION: One of a plurality of base stations is an associated base station of a CoMP user device to transmit data to the CoMP user device. The base stations include multiple CoMP base stations for the CoMP user device. The CoMP base stations for the CoMP user device transmit CoMP downlink data, including subframes which comprise physical resource blocks having a plurality of resource elements (REs) and cell-specific reference signal (CRS) resource element (RE) locations. PDSCH bit-level muting or puncturing information is determined on the basis of radio resource management measurement and the subframes sent from the multiple CoMP base stations, to identify PDSCH REs that suffer strong CRS interference transmission from within the multiple CoMP base stations and are to be subjected to one of bit-level muting or bit-level puncturing.
