WIRELESS COMMUNICATION APPARATUS AND METHOD FOR CONTROLLING WIRELESS COMMUNICATION APPARATUS
First Claim
1. A wireless communication apparatus that performs simultaneous communication with a plurality of communication terminals by using the same frequency band, the apparatus comprising:
- a request unit that requests each of the communication terminals to send feedback information representing a status of a communication channel used in communication;
a reception unit that receives the feedback information from the communication terminals;
a storage unit that stores the feedback information received by the reception unit;
an acquisition unit that acquires a correlation value between the latest feedback information received by the reception unit and the feedback information previously stored in the storage unit for each of the communication terminals;
a measurement unit that measures a delay time from when the feedback information is requested from the request unit to when the feedback information is received by the reception unit;
a generation unit that generates a reliability parameter representing degree of error that is allowed in the feedback information received from the each of the communication terminals based on the correlation value and the delay time; and
a selection unit that selects two or more of the communication terminals from among the plurality of the communication terminals based on the reliability parameter.

Abstract
A wireless communication apparatus performs simultaneous communication with a plurality of communication terminals by using the same frequency band. The apparatus including: a reception unit that receives feedback information from each of the communication terminals; an acquisition unit that acquires a correlation value between the latest feedback information and the feedback information previously stored in a storage unit for each of the communication terminals; a measurement unit that measures a delay time relating to the feedback information; a generation unit that generates a reliability parameter representing degree of error that is allowed in the feedback information based on the correlation value and the delay time; and a selection unit that selects two or more of the communication terminals from among the plurality of the communication terminals based on the reliability parameter.
