Claim:
1. A communication method for a control channel, wherein the control channel comprises at least one timeslot, and the method comprises: obtaining by a transmitting terminal, according to a first data symbol sequence [q(0), q(1), . . . , q(M−1)] to be transmitted in a timeslot and coefficients a(i) and d(i), a second data symbol sequence [a(0), q(0)a(1)q(1), . . . , a(M−1)q(M−1)] and a third data symbol sequence [d(0)q(0), d(1)q(1), . . . , d(M−1)q(M−1)], wherein, in a(i)+d(i), at least one pair of a(u)+d(u) and a(v)+d(v) have unequal moduli and are thus substantially orthogonal to each other; and using the same extension sequence [w(0), w(1), . . . , w(N−1)] to process the second data symbol sequence and the third data symbol sequence as processed data, mapping by the transmitting terminal based on the unequal moduli the processed data respectively onto the same time-frequency resources corresponding to a first antenna array and a second antenna array, and transmitting the mapped data by the first antenna array and the second antenna array over the control channel, wherein, i, u, and v are integers, 0≦i≦M−1, 0≦u≦M−1, 0≦v≦M−1.
