Patent ID: 7426680

Claim:
An encoding method for encoding TFCI (Transport Format Combination Indicator) bits for a DCH (Dedicated Channel) and TFCI bits for a DSCH (Downlink Shared Channel) in a mobile communication system including an encoder for encoding k input TFCI bits and (10-k) TFCI bits, where k is an integer with a value in the range from 1≦k≦9, the method comprising the steps of: generating a first coded bits by encoding the k input bits into 32 bits, and outputting a (3k+1)-bits by puncturing the first coded bits according to a specific mask pattern associated with the value of the k; and generating a second coded bits by encoding the (10-k) input bits into 32 bits, and outputting a {3*(10-k)+1}-bits by puncturing the second coded bits according to a specific mask pattern associated with the value of the (10-k).
