Document Type and Number:
WIPO Patent Application WO/2017/077705
Kind Code:
A1
Abstract:
Scrambling code is initialised based on a parameter, n'RNTl, that changes from a given block of sub-frames to a subsequent block of sub-frames wherein the parameter is derived using one of the following formulas: n'RNTl = (nINTI +SFN) mod 216 n'RNTl = (nRNTI +k) mod 216 where nRNTl is a temporary identifier associated with a mobile device connected to said cell and for which said scrambling code is applicable; and SFN is a system frame number associated with said at least one of said sequence of sub-frames; and k is a sub-frame counter.
