US 2010/0075689 A1 · MOBILE COMMUNICATION SYSTEM, BASE STATION APPARATUS, AND MOBILE STATION APPARATUS

Abstract

To improve throughput of the whole system while reducing power consumption. In a mobile communication system comprising a mobile station apparatus and a base station apparatus, the base station apparatus creates an interference information table based on channel quality of an uplink channel, and at the same time, transmitting the interference information indicator table to the mobile station apparatus, and the mobile station apparatus determines a state of interference in an uplink frequency band based on the interference information indicator table, determines a frequency band of a measurement pilot channel, which is a pilot channel used to determine received quality, and make a request to the base station apparatus for a transmission resource. For example, the mobile station apparatus determines a frequency band with lowest interference among the uplink frequency bands as a frequency band of the measurement pilot channel.

1-28. (canceled)

A mobile communication system comprising a mobile station apparatus and a base station apparatus, wherein:

said base station apparatus comprises:
a cell edge determination step which determines whether or not said mobile station apparatus is located on a cell edge;
an interference determination step which determines a state of interference for each predetermined frequency band based on channel quality of said mobile station apparatus determined to be located on a cell edge by said cell edge determination step;
and
a table creation step which creates an interference information indicator table based on the determination result for each frequency band by said interference determination step;
and
said mobile station apparatus performs a data transmission in accordance with the allocation of transmission resource based on said interference information indicator table created by said base station apparatus.
