摘要：The present invention is designed to provide a radio communication system, a
user terminal and a radio communication method that make it possible to monitorcommunication quality adequately even when a new radio resource structure is
employed. A radio communication system is provided, which transmits downlink controlinformation from a radio base station to a user terminal by using an enhanced downlinkcontrol channel that is frequency-division-multiplexed with a downlink shared datachannel, and which also monitors downlink quality based on the received quality ofdownlink reference signals that are transmitted from the radio base station to the userterminal, and, in this radio communication system, the user terminal determines radio linkfailures by comparing the received quality of the downlink reference signals transmittedfrom the radio base station, against one or both of first criteria, which are constituted oftwo thresholds that correspond to predetermined block error rates of a downlinkcontrol channel, and second criteria, which are constituted of two thresholds that aredifferent from the two thresholds of the first criteria.
