A method and apparatus for transmitting a synchronization signal

The present invention discloses a method and apparatus for transmitting a synchronization signal, to solve the conventional radio communication system standards result in high cost. The transmission method is applied to LTE using a standard series of a communication system, comprising: a network-side network element to generate a synchronization signal enhancement; network-side network element sends a synchronization signal to the enhanced enhanced terminal, wherein the enhanced synchronization signal when using the frequency resource type synchronous signal is different from the basic frequency resource allocation used. The apparatus comprising: a generating module and a sending module. The present invention is enhanced by a series of standards of LTE synchronization channel, can effectively reduce power consumption of terminals and implementation complexity, lower cost, better meet the needs of the user data and the future development of the rapid development of wireless communication industry.
