One of the objects of the present invention is to more completely avoid impossibility of access between a mobile station and a base station, in wireless communication using an OFDM modulation scheme. A mobile station (110) generates a timing correction channel (first time) to be frame synchronized with a notification channel.A base station (120) 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.
