SENDING METHOD AND DEVICE FOR 8-ANTENNA DOWNLINK CONTROL CHANNEL

摘要

A sending method and device for an 8-antenna downlink control channel, comprising: for eight antennas used for downlink transmission of a base station, 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, wherein 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, or the weighted value of one antenna is -1 and the weighted values of the other three antennas are +1; and the base station sending downlink control signals through the first port and the second port. The method can expand the coverage of the downlink control channel of the base station using eight antennas.
