Abstract
To perform rate matching appropriately even when downlink signals are transmitted from a plurality of transmission points to a user terminal, a radio communication system having a user terminal capable of coordinate multi-point transmission and reception with several radio base stations is provided. A radio base station transmits downlink control information including bit information defining a predetermined rate matching pattern to the user terminal. The user terminal receives the downlink control information and performs rate matching based on the bit information defining the rate matching pattern. A combination of a cell-specific reference signal pattern and an interference measurement reference signal pattern in the case of transmission from several radio base stations each using an MBSFN subframe or NCT is defined in predetermined bits. The user terminal performs rate matching based on the bit information and the subframe configuration and interference measurement reference signal pattern of the radio base station.
