Wireless communication method, wireless communication system, base station and mobile station
Abstract:
There is provided a wireless communication method, a wireless communication system, a base station and a mobile station which conduct wireless communication using an OFDM modulation scheme. The base station transmits a timing correction burst to the mobile station only when a correlation peak detected from a received OFDM symbol is within a predetermined timing detection range. If the timing correction burst is not introduced from the base station even after expiration of predetermined time duration, by copying a signal by a length different from a guard interval from the end of an effective symbol and adding the copied signal to the front of the effective symbol, the mobile station generates a new timing correction channel (second time), in which transmission timing of a previously generated timing correction channel is shifted.
