Abstract
The embodiment of the invention provides a synchronization method, base station and terminal. A first transmission position of a PSS and a second transmission position of an SSS on a NCT carrier wave are determined, the first transmission position is a transmission position of the SSS on a non-NCT carrier wave, and the second transmission position is a transmission position of the PSS on the non-NCT carrier wave, so that the PSS is emitted at the first transmission position on the NCT carrier wave, the SSS is emitted at the second transmission position on the NCT carrier wave, and the terminal supporting the NCT carrier wave performs synchronization on the NCT carrier wave according to the PSS and the SSS. Only the terminal supporting the NCT carrier wave (namely the NCT carrier wave terminal) can receive the PSS and the SSS accurately, the terminal which does not support the NCT carrier wave (namely the non-NCT carrier wave terminal, also can be called an Iegacy terminal) can not receive the PSS and the SSS accurately, so that the NCT carrier wave terminal performs the synchronization immediately, and the Iegacy terminal does not need to perform the synchronization, and synchronization performance of the terminals is improved.

Alternatively, a possible implementation of the present embodiment, base station is without to described terminal, sending indication information, and terminal can also be further obtains described indication information according to pre-configured, for example, the agreement agreement.
Alternatively, a possible implementation of the present embodiment, the configuration information of described NCT carrier wave can include but not limited to cell identity information and NCT carrier identification; Perhaps NCT carrier identification.
In the present embodiment, terminal receives the PSS sent on first transmission location of base station on the NCT carrier wave by receiver, and receive the SSS sent on second transmission location of described base station on described NCT carrier wave, the transmission location that described the first transmission location is the SSS on non-NCT carrier wave, the transmission location that described the second transmission location is the PSS on described non-NCT carrier wave, make the processor can be according to described PSS and described SSS, on described NCT carrier wave, carry out synchronous, owing to only having, support the terminal (being the NCT carrier terminal) of NCT carrier wave can correctly receive described PSS and described SSS, do not support that the terminal of NCT carrier wave (is non-NCT carrier terminal, can also be called the Iegacy terminal) can't correctly receive described PSS and described SSS, therefore, the NCT carrier terminal can be carried out rapidly synchronously, the Iegacy terminal is synchronous without carrying out, thereby improved the net synchronization capability of terminal.
In addition, if base station can be by forbidding the access NCT carrier wave of the method restriction Iegacy terminals such as (bar) information, random access, so, because base station has adopted technical scheme of the present invention, make the Iegacy terminal synchronous without carrying out, therefore, avoided because the Iegacy terminal is carried out after synchronous the problem of the processing load of base station in synchronizing process that has been limited again to access increase that the NCT carrier wave causes, thereby can effectively save interface-free resources.
