Claim:
A method that facilitates sending channel quality indicator (CQI) information in a wireless communication environment, comprising: encoding CQI information to yield a sequence of coded CQI bits; modulating the coded CQI bits to yield a sequence of modulated symbols; mapping the modulated symbols to a physical uplink control channel (PUCCH); and transmitting the CQI information to a base station via the PUCCH, wherein the CQI information is denoted by a n , the coded CQI bits are denoted by b i , where i =0, 1, 2, . . . , B-1, B=20, with b i = ∑ n = 0 A - 1 ⁢ ( a n · M i , n ) ⁢ mod ⁢ ⁢ 2 , A is a positive integer greater than zero, and [M i,n ] is a matrix obtained by performing row permutation on the following matrix: i M i,0 M i,1 M i,2 M i,3 M i,4 M i,5 M i,6 M i,7 M i,8 M i,9 M i,10 M i,11 M i,12 0 1 1 0 0 0 0 0 0 0 0 1 1 0 1 1 0 1 0 1 0 1 0 1 1 1 1 1 2 1 1 0 1 1 1 1 1 0 0 0 0 0 3 1 0 0 1 0 0 1 0 1 1 1 1 1 4 1 1 1 0 0 0 0 0 0 1 1 1 0 5 1 0 0 1 1 1 0 0 1 0 0 1 1 6 1 0 1 0 0 1 1 1 0 1 1 1 1 7 1 1 0 0 1 0 1 1 1 0 1 1 1 8 1 1 0 1 0 1 0 1 0 1 1 1 1 9 1 0 1 1 1 0 1 0 0 1 1 1 1 10 1 0 0 0 1 1 0 1 0 0 1 0 1 11 1 0 1 1 0 0 0 0 1 0 1 1 1 12 1 1 0 1 1 0 0 1 0 1 1 1 1 13 1 1 0 0 1 1 1 1 0 1 1 0 1 14 1 1 1 0 0 1 1 0 1 0 1 1 1 15 1 0 0 1 0 1 0 1 1 1 1 1 1 16 1 1 1 0 1 1 1 0 0 1 0 1 1 17 1 0 0 1 1 0 0 1 1 0 1 1 1 18 1 1 1 1 0 0 0 1 0 0 1 1 1 19 1 0 0 0 0 1 1 0 0 0 0 0 0.
