APPARATUS AND METHOD FOR TRANSMITTING TFCI BITS FOR A HARD SPLIT MODE IN A CDMA MOBILE COMMUNICATION SYSTEM

摘要

An encoding method and apparatus for a DCH (Dedicated Channel) encoder and a DSCH (Downlink Shared Channel) encoder in a transmitter for a mobile communication system including the DCH encoder for encoding k bits among 10 input TFCI (Transport Format Combination Indicator) bits and the DSCH encoder for encoding remaining (10-k) bits among the input TFCI bits. The method comprises generating, by the DCH encoder, a first coded bit stream by encoding the k input bits into 32 bits, and outputting a (3 k+1)-bit stream by puncturing the first coded bit stream according to a specific mask pattern corresponding to the k value; and generating, by the DSCH encoder, a second coded bit stream by encoding the (10-k) input bits into 32 bits, and outputting a {3*(10-k)+1}-bit stream by puncturing the second coded bit stream according to a specific mask pattern corresponding to the (10-k) value.
