<P>PROBLEM TO BE SOLVED: To provide a communication processing of a user's facility, and the user's facility. <P>SOLUTION: In the communication processing method of the user's facility, the user's facility sets up a first decoding vector by utilizing a presumed channel and one vector in a code book, and an equivalent channel is calculated by utilizing the first decoding vector, and a receiving SINR is acquired from the first decoding vector to the maximum extent. Alternately, the minimum angular difference resides between the equivalent channel and one vector in the code book. The user's facility calculates a CDI and a CQI by utilizing the equivalent channel, and feeds back the CDI and the CQI to a base station, and performs decoding by using a second vector. While raising a frequency spectrum efficiency, a down channel resource is also saved on. <P>COPYRIGHT: (C)2011,JPO&INPIT |
