Abstract:
1. A method for measuring channel quality of a Base Station (BS) by using a ranging signal in a wireless communication system, the method comprising: estimating a time offset of the ranging signal received through a ranging channel; measuring channel quality by using a signal from an extraction section of the ranging signal determined based on the estimated time offset; determining whether the extraction section of the ranging signal starts no earlier and ends no later than a ranging channel duration by using the time offset; determining whether distortion occurs in the measured channel quality based on a result of the determination of whether the extraction section of the ranging signal starts no earlier and ends no later than the ranging channel duration; and compensating for distortion of the measured channel quality, wherein the ranging channel duration comprises one of an initial ranging signal comprising exactly two symbols in a time axis and a periodic ranging signal comprising exactly one symbol in the time axis.
