Abstract  Abstract

using OFDM in the cellular system it is necessary to forward link synchronization channel common pilot channel structure initial cell search method mobile station and an adjacent cell search method for handover. comprising: generating a plurality of frames including synchronous block according to a method for transmitting a forward synchronization signal in a wireless communication system method of the present invention; and transmitting the frame through a forward link a plurality of secondary synchronous channel sequence wherein the frame comprises timing information provided by the timing information of the synchronization block main synchronous channel sequence and provides the frame wherein through the primary synchronous channel sequence and the combination of the frequency hopping code words in the plurality of secondary synchronous channel sequence to specify cell identifiers. therefore it can effectively reduce cell search time in the 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.
