Patent GB-2544103-A (GB)
Title: Communication system
Inventor: ROBERT ARNOTT
IPC: H04W72/04
Filed: 2015-11-06
Abstract: A communication system is disclosed in which communication apparatus (such as a base station 5 and/or a mobile telephone 3) derives a scrambling code based on a parameter that changes from radio frame to radio frame. Using the scrambling code, the communication apparatus scrambles signals upon transmission and de-scrambles signals upon reception. The parameter is derived based on at least one of: a system frame number associated with at least one of said sequence of sub-frames; and a counter, and allows a scrambling sequence that is longer than one radio frame (13, figure 2) and is different to the scrambling sequence used in any neighbouring cell 7. Suitable for coverage enhanced machine-type communication (MTC) device deployment in which a base station 5 duplicates transmitted information in the time domain (the base station retransmits the same information in one or more sub-frames). Reduces inter-cell interference (ICI) by preventing long repetition (coverage enhancement) transmissions from combining coherently. Using the disclosed parameter (which changes from radio frame to radio frame) for deriving a scrambling sequence, achieves a higher signal-to-interference-plus-noise ratio (SINR) than using legacy scrambling sequences that is repeated in every radio frame.
