<P>PROBLEM TO BE SOLVED: To provide a radio communication device for reporting radio channel quality information corrected by utilizing the information based on decoding processing of a received signal to a base station in order to improve the estimation accuracy of the radio channel quality information. <P>SOLUTION: The radio communication device 1 in a radio communication system for executing adaptive link control based on the radio channel quality information includes: a channel quality estimating section 2 for estimating an SN ratio of a received signal; a demodulating section 3 for demodulating the received signal; a decoding section 4 for executing soft decision decoding for the demodulated received signal; a correcting section 5 for correcting the SN ratio estimated by the channel quality estimating section 2 by utilizing the likelihood information acquired with by the soft decision decoding; a converting section 6 for converting the SN ratio corrected by the correcting section 5 into the radio channel quality information; and a transmitting section 7 for transmitting the radio channel quality information converted by the converting section 6 to a signal transmission side. <P>COPYRIGHT: (C)2010,JPO&INPIT |
