METHOD OF SENDING CHANNEL QUALITY INFORMATION IN MULTI-CAREER RADIO COMMUNICATIONS SYSTEM, CORRESPONDING USER TERMINAL, AND BASE STATION |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method of acquiring channel quality information in a base station of a multi-career radio communications system which has two or more orthogonal frequency subcarriers. <P>SOLUTION: The method includes: a step of measuring a channel frequency response of the multi-career radio communications channel with a user terminal; a step of extracting a sample of the channel frequency response expressed with a prescribed oversampling factor in a frequency domain; a step of sending the sample to the base station via a signal channel from the user terminal; a step of carrying out window processing to a receiving sample in a time domain; and a step of determining channel quality information about the respective subcarrier by frequency domain expression of the receiving sample after the window processing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
