Abstract  Abstract

In a cellular system in which it is used OFDM are required for synchronizing channel sending connection a structure of pilot channel common a method of cell initial search of a mobile station and a method for searching the adjacent cell for handover. A method of transmitting a synchronization signal in a communication system send wireless according to the present invention includes the generation of a frame comprising a plurality of synchronization blocks; and transmission frame by means of a connection for sending in which the frame comprises sequences of primary synchronization channel from which information blocks of time synchronization and a plurality of sequences of secondary synchronization channel from the time information of the frame wherein a cell identifier is specified by a combination of the sequence of primary synchronization channel and a hopping code word specified by the plurality of sequences of secondary synchronization channel. In this way the seek time of cell can be efficiently reduced in an ofdm system.

In a cellular system in which OFDM is used a forward link synchronization channel a common pilot channel structure an initial cell searching method of a mobile station and an adjacent cell searching method for handover are required. A method of transmitting a forward synchronization signal in a wireless communication system according to the present invention includes generating a frame comprised of a plurality of sync blocks; and transmitting the frame through a forward link wherein the frame comprises primary synchronization channel sequences which provide timing information of the sync blocks and a plurality of secondary synchronization channel sequences which provide timing information of the frame wherein a cell identifier is specified by a combination of the primary synchronization channel sequence and a hopping code word specified by the plurality of the secondary synchronization channel sequences Therefore the cell searching time can be efficiently reduced in an OFDM system.
