RANGING METHOD IN A BROADBAND WIRELESS COMMUNICATION SYSTEM AND AN APPARATUS THEREOF FOR IMPROVING SYSTEM DATA TRANSMISSION PERFORMANCE

摘要

PURPOSE: A ranging method in a broadband wireless communication system and an apparatus thereof for improving system data transmission performance are provided to reduce probability of error in data modulation from a terminal.;CONSTITUTION: A ranging method in a broadband wireless communication system and an apparatus thereof for improving system data transmission performance are as follows. The movement speed of the terminal is estimated(403). A ranging cycle is changed according to the movement speed(405). The ranging is performed according to the changed ranging period. The ranging cycle change changes the related function of the preset movement speed and ranging period.;COPYRIGHT KIPO 2010
