PSEUDO-RANDOM SEQUENCE MAPPING IN WIRELESS COMMUNICATION Russian patent published in 2012 - IPC H04B1/707 

FIELD: information technology.

SUBSTANCE: systems and methodologies are described, which facilitate scrambling of downlink reference signals utilising a pseudo-random sequence (PRS) corresponding to a primary synchronisation code (PSC) and secondary synchronisation code (SSC) combination. Use of the combination allows for orthogonal sequencing to be removed from the scrambling. This can be beneficial, for example, where resources required for the orthogonalisation of the reference signal outweigh the benefit of utilising the orthogonal sequences. In such scenarios, selective scrambling can be utilised such that the orthogonal sequence or instead the PSC/SSC combination can be provided to efficiently use advantages of both mechanisms in the given scenarios.

EFFECT: increased noise immunity.
