Abstract: A channel coding method of variable length information using block code is disclosed. A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of minimum Hamming distance.
