<P>PROBLEM TO BE SOLVED: To provide a radio base station device, a mobile terminal device, and a radio communication method, capable of transmitting and receiving a channel quality measurement reference signal of a downlink, while taking into account high-precision estimation of interference. <P>SOLUTION: In the radio communication method, the radio base station device generates a channel quality measurement reference signal and maps the channel quality measurement reference signal to adjacent two symbols, and the mobile terminal device receives a downlink signal containing the channel quality measurement reference signal mapped to the adjacent two symbols, and estimates the interference power by using the channel quality measurement reference signal mapped to the adjacent two symbols. <P>COPYRIGHT: (C)2011,JPO&INPIT |
