Abstract:
1. A base station apparatus that communicates with a mobile station apparatus, comprising: a measuring part for measuring channel quality of an uplink channel received from said mobile station apparatus; a division part for dividing a frequency band of said uplink channel into a predetermined number of bands to acquire channel quality of said uplink channel for each of said divided frequency bands; and a determination part for determining a state of interference for each of said divided frequency bands based on said acquired channel quality, wherein the base station apparatus creates an interference information indicator table that is transmitted to another base station apparatus for showing said state of interference for each of said divided frequency bands by a plurality of magnitude relationships, wherein the base station apparatus creates an interference information indicator table across a system bandwidth that is transmitted to another base station apparatus for showing said state of interference for each of said divided frequency bands by a plurality of magnitude relationships.
