Abstract
In order to minimize deterioration in the reception accuracy even when downlink signals are transmitted from transmission points to a user terminal, a radio communication method for multiple radio base stations and a user terminal capable of communicating with the radio base stations is provided. The method involves transmitting downlink control information, a UE-specific reference signal and a channel state measurement reference signal to the user terminal, transmitting information about configuration of the channel state measurement reference signal, transmitting association information in which the configuration of the channel state measurement reference signal is associated with an information element contained in the downlink control information, determining a channel state measurement reference signal that is associated with a received UE-specific reference signal based on the association information, and performing reception processing, assuming that the UE-specific reference signal and the channel state measurement reference signal are transmitted from a same radio base station.
