GENERATION OF USER EQUIPMENT IDENTIFICATION SPECIFIC SCRAMBLING CODE FOR THE HIGH SPEED SHARED CONTROL CHANNEL

摘要

The present invention provides embodiments for producing a user equipment identification scrambling sequence (UEIDSS). The produced sequences for different user identification codes have a high separation. A base station uses the UEIDSS to scramble a high speed shared control channel (HSSSCH) and a user equipment (UE) uses the UEIDSS to descramble the HSSSCH. The embodiments utilize various blocks for producing the codes. These blocks include Reed-Muller encoding (22), concatenation (24), rate matching (26), segmentation (20), convolutional encoding (44); tail bit discarding (46), zero padding (76), repeating (74), CRC calculation (62), quadratic residue coding (78), parity-check bit (80), shortening (82), puncturing (40) and BCH encoding blocks (86).
