SIGNALING METHOD, BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS AND RADIO COMMUNICATION SYSTEM

摘要

To provide a signaling method for enabling position information of muting resources to be signaled with a simplified configuration, base station apparatus and mobile terminal apparatus, the signaling method is characterized by having the steps of setting blank resources for a CSI-RS (Channel State Information-Reference Signal) that is a reference signal for downlink channel estimation, and transmitting a bitmap indicative of a position of the blank resources to a mobile terminal apparatus.
