The present invention provides a communication method for a control channel and an apparatus, where the control channel includes at least one timeslot, and the method includes: obtaining, according to a first data symbol sequence [ q (0), q (1),L 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),L , a ( M -1) q ( M -1)] and a third data symbol sequence [ a (0) q (0), a (1) q (1),L , a ( M -1) q ( M -1)], where, in a ( i )+ d ( i ), at least one pair of a ( u )+ d ( u ) and a ( v )+ d ( v ) have unequal moduli; and using the same extension sequence [ w (0), w (1),L , w ( N -1)] to process the second data symbol sequence and the third data symbol sequence, mapping the processed data respectively onto the same time-frequency resources corresponding to a first antenna array and a second antenna array, and transmitting the data, where i, u , and v are integers, 0‰¤ i ‰¤ M -1, and u ‰¤ v . |
