Generation of user equipment identification specific scrambling code for the high speed shared control channel

Abstract

A code is produce for use in scrambling or descrambling data associated with a high speed shared control channel (HS-SSCH) for a particular user equipment. A user identification of the particular user equipment comprises L bits. A 1/2 rate convolutional encoder processes at least the bits of the user identification by a 1/2 rate convolutional code to produce the code.
