<P>PROBLEM TO BE SOLVED: To reduce interference given by a transmission timing control signal to other channels in the same cell and amount of interference given to other cells in downlink transmission, in a wireless communication system based on adaptive transmission timing control techniques. <P>SOLUTION: In a wireless communication system based on an adaptive transmission timing control techniques wherein a base station 10 extracts paths having power levels that exceed a prescribed threshold from delay profiles of a terminal station as available paths, selects a path having a maximum power or the leading path from available paths as a reference path, calculates time difference between an arrival time of a reference path and a prescribed maximum arrival time, and transmits the results to a terminal station as a transmission timing control signal; and the terminal station adjusts the transmission timing to the base station 10 according to the calculated time difference, the base station 10 transmits the transmission timing control signal to the terminal station only when it detects the reference path. <P>COPYRIGHT: (C)2009,JPO&INPIT |
