Abstract: A method for an 8-antenna downlink control channel, is described. the method includes virtualizing a first pair and a third pair of dual-polarized antennas as a first port, and virtualizing a second pair and a fourth pair of dual-polarized antennas as a second port. The weighted values of the broadcast right of the four antennas in the first port satisfy that the weighted value of one antenna is +1 and the weighted values of the other three antennas are ?1, or the weighted value of one antenna is ?1 and the weighted values of the other three antennas are +1, and weighted values of the broadcast right of the four antennas in the second port satisfy that the weighted value of one antenna is +1 and the weighted values of the other three antennas are ?1.
