BASE STATION, MOBILE STATION AND SYNCHRONISATION CHANNEL TRANSMISSION METHOD Russian patent published in 2012 - IPC H04J11/00 

FIELD: information technology.

SUBSTANCE: invention discloses a base station used in a mobile communication system comprising several cells consisting of several sectors. The base station has a synchronisation channel generating unit which generates a synchronisation channel for use during cell search by a user terminal, and a transmission unit which wirelessly transmits a signal, having a synchronisation channel. The synchronisation channel has a primary synchronisation channel and a secondary synchronisation channel. The primary synchronisation channel has a series of several types, and the secondary synchronisation channel, transmitted to a cell sector, has a code, predetermined based on a given polynomial generating equation, which corresponds to the primary synchronisation channel.

EFFECT: reduced effect of intersymbol interference and shorter time for cell search.
