25.2223GPPMultiplexing and channel coding (TDD)Release 17TS
The bits output from the TrCH multiplexer are scrambled in the bit scrambler. The bits input to the bit scrambler are denoted by
, where S is the number of bits input to the bit scrambling block equal to the total number of bits on the CCTrCH. The bits after bit scrambling are denoted 
.
Bit scrambling is defined by the following relation:
