The PSC carried by PSCH is the cell identification code, which is used to search the cell. The SSC carried by SSCH is a 16 scrambling code group, which is divided into 15 time slots of a frame, and finally 64 SSC possibilities are formed, that is, 64 scrambling code sequences stipulated in the protocol. There are 5 12 main scrambling codes, which are divided into 64 groups of scrambling codes with 8 in each group. The terminal obtains SSC scrambling code sequence through synchronous SSCH, and then matches the group specified in the protocol to obtain the cell main scrambling code and frame synchronization position.
So PSCH and SSCH are orthogonal ~ ~
Take it. Wow.
