Wireless communication system, base station, and wireless communication method

摘要

In a wireless communication system, a base station 10 extracts paths having power levels that exceed a predetermined threshold value from delay profiles of a terminal station as available paths, selects a path having a maximum power or the first path from available paths as a reference path, calculates time difference between an arrival time of a reference path and a predetermined maximum arrival time, and transmits the result 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. Interference given by a transmission timing control signal to other channels in the same cell and other cells in downlink transmission is reduced.
