Method and apparatus for encoding and decoding high speed shared control channel


Abstract
A method and apparatus for encoding and decoding high speed shared control channel (HS-SCCH) data are disclosed. For part 1 data encoding, a mask may be generated using a wireless transmit/receive unit (WTRU) identity (ID) and a generator matrix with a maximum minimum Hamming distance. For part 2 data encoding, cyclic redundancy check (CRC) bits are generated based on part 1 data and part 2 data. The number of CRC bits is less than the WTRU ID. The CRC bits and/or the part 2 data are masked with a mask. The mask may be a WTRU ID or a punctured WTRU ID of length equal to the CRC bits. The mask may be generated using the WTRU ID and a generator matrix with a maximum minimum Hamming distance. The masking may be performed after encoding or rate matching.
