RADIO COMMUNICATION METHOD, RADIO COMMUNICATION SYSTEM, AND USER TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide CSI feedback, PDSCH RE mapping, and resource allocation which are effective to coordinated multipoint transmission and reception (CoMP).SOLUTION: A radio communication system supporting a coordinated multipoint transmission and reception (CoMP) includes user equipment (UE) and a network controller which notifies a codebook subset for each channel state information (CSI) process to the user equipment in a quasi-static manner. The UE is restricted with an indication report of a pre-coding matrix in the codebook subset.SELECTED DRAWING: Figure 6
