The present application relates to the field of communications, and provides a downlink channel precoding method and apparatus. The downlink channel precoding method provided in an embodiment of the present application comprises: acquiring a downlink channel estimation result; determining a precoding matrix of each group of antennas according to grouping condition of antennas of a base station and the downlink channel estimation result; and precoding a downlink signal according to the precoding matrix of each group of antennas. In the downlink channel precoding method provided in the embodiment of the present application, by grouping antennas of a base station and precoding the grouped antennas of the base station in the unit of antennas, the complexity of hardware implementation is reduced when a high-performance precoding method is used in a large-scale MU-MIMO system. |
