摘要 |
One object 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 (Orthogonal Frequency Division Multiplexing) modulation scheme. A PHS terminal (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 PHS terminal (110) 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 (120) even after expiration of predetermined time duration, the PHS terminal (110) generates a new timing correction channel (second time), in which transmission timing of a previously generated timing correction channel is shifted.
