WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD

摘要

A wireless communication apparatus is capable of improving communication efficiency by reducing the amount of control information transmitted. A channel quality information extraction section extracts CQI's from a received signal. An allocation control section allocates subcarriers for every communication terminal apparatus and selects a modulation scheme in such a manner that required transmission rate is satisfied for each communication terminal apparatus based on required transmission rate information, etc. and CQI's for communication terminal apparatus of each user. A required subcarrier number determining section decides the number of subcarriers allocated to every communication terminal apparatus so as to satisfy the required transmission rate for each communication terminal apparatus. A required subcarrier number information generating section generates information for the number of subcarriers allocated to every communication terminal apparatus. A subcarrier allocation section allocates packet data to selected subcarriers. Modulating sections adaptively modulate packet data allocated to each subcarrier.

主权项

1. A communication apparatus, comprising:
a receiver configured to receive control information; a subcarrier selector configured to select a quantity of subcarriers in a communication band based on the received control information; a channel quality information generator configured to generate subcarrier channel quality information (CQI); and a CQI selector configured to select, based on the received control information, one of:
subcarrier CQI of all subcarriers of the communication band without position information; andsubcarrier CQI and position information of the selected subcarriers.
