Claim:
1. A communication control method comprising: calculating, by a first base station, a first statistic for each piece of first precoder matrix information fed back from a first user terminal and a second statistic for each downlink radio resource in the first user terminal; notifying, by the first base station, a second base station of the first statistic and the second statistic; calculating, by the second base station, a third statistic for each piece of second precoder matrix information fed back from a second user terminal and a fourth statistic for each downlink radio resource in the second user terminal; and comparing, by the second base station, the first statistic with the third statistic, comparing the second statistic with the fourth statistic, and determining whether a spatial multiplexing transmission applying a same radio resource and a same precoder matrix to the first user terminal and the second user terminal is possible.
