FIELD: information technology.
SUBSTANCE: scrambled secondary synchronisation codes (SSC) can be assigned to multiple base stations of a radio access network (RAN). As an example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSC. Selection can be based on transmission characteristics of resulting SSC, providing reduced interference in planned, semi-planned and/or unplanned mobile communication medium.
EFFECT: reduced interference in a mobile communication network by providing secondary synchronisation coding using a main synchronisation channel-associated scrambling code.
