1. A mobile communication system in which a finite number of reference signal sequences are reused among multiple cells, comprising a base station:
- the base station comprising;
a measuring unit configured to measure interference power for each frequency band from another cell to which the same reference signal sequence is assigned by measuring a difference between a channel estimation value by means of sounding reference signals and a channel estimation value by means of reference signals for channel estimation; and
a determining unit configured to determine a frequency band based on the measured interference power.

Abstract
A mobile communication system in which a finite number of reference signal sequences used for uplink channel estimation or the like are reused among multiple cells includes a determining unit configured to determine a frequency band used by user terminals to which a reference signal sequence with a predetermined sequence length is assigned in each of the cells within an interference area, wherein the frequency band is determined to be different from frequency bands used in the other cells.
