Claim:
A method of coding channel quality information (CQI), comprising the steps of: providing information bits, a 0 , a 1 , a 2 , a 3 , and a 4 ; providing five basis sequences M i,n for a (20,5) CQI code; encoding the information bits by combining the information bits with the basis sequences; and generating a 20-bit codeword, wherein the basis sequences M i,n are defined as: I M i,0 M i,1 M i,2 M i,3 M i,4 0 1 0 0 0 1 1 0 1 0 0 1 2 1 1 0 0 1 3 0 0 1 0 1 4 1 0 1 0 1 5 0 1 1 0 1 6 1 1 1 0 1 7 0 0 0 1 1 8 1 0 0 1 1 9 0 1 0 1 1 10 1 1 0 1 1 11 0 0 1 1 1 12 1 0 1 1 1 13 0 1 1 1 1 14 1 1 1 1 1 15 0 0 0 0 1 16 0 0 0 0 1 17 0 0 0 0 1 18 0 0 0 0 1 19 0 0 0 0 1.
