TRANSMITTER AND RECEIVER IN CELLULAR COMMUNICATIONS SYSTEM Russian patent published in 2012 - IPC H04J11/00 

FIELD: information technology.

SUBSTANCE: in cellular communications system with multiple carriers, the second code of synchronisation (Walsh code or serial GCL code), mapped on the second synchronising channel is used as the signal for determination in which cell of base station the mobile station terminal device itself is located. Signal transmitted from base station to mobile station terminal device is mapped into radiocommunication frame which is two-dimensional in directions of time and frequency. The synchronising channel into which the first and the second synchronising channels are mapped is imbedded in multiple areas in radiocommunication frame. When certain series number of the second code for cell or cells group determination is mapped into radiocommunication frame, to the second synchronisation code phase slue or cyclic shift is applied where one radiocommunication frame comprises one cycle. On the receiving side, frame header timing data is determined through obtaining information relative to phase slue angle or amount of the second synchronisation code cyclic shift.

EFFECT: high synchronisation accuracy.
