Claim:
1. A radio communication method for a plurality of radio base stations and a user terminal capable of communicating with the plurality of radio base stations, the radio communication method comprising the steps of: by the radio base station, 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 in formation; and by the user terminal, determining the channel state measurement reference signal that is associated with the 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 stations wherein the radio base station instructs the user terminal to either determine or to not determine the channel state measurement reference signal associated with the received UE-specific reference signal based on the association information received by the user terminal.
