1. A method for wireless communication, comprising:

transmitting, by a wireless device over a control channel, an M-bit payload on N symbols over a plurality of subcarriers,

wherein M and N are positive integers, wherein M is greater than 2,

wherein each of the N symbols is represented using a base sequence and a cyclic shift (n_cs(n, m)) of the base sequence,

wherein n=0, 1, . . . (N−1) is a non-negative integer that indexes a symbol in the N symbols, and wherein m=0, 1, . . . (2^M−1) is a non-negative integer that indexes a combination set in 2^Mcombination sets.
