Data processing method and base station

Provided are a data processing method and a base station, which relate to the field of communications and are used for reducing the interference of other antenna systems to a terminal acquiring data information. The method comprises: determining an effective antenna and an interference antenna of a terminal; determining a location of first data in a first data packet, wherein the first data packet refers to a data packet which is sent by means of the interference antenna and sent together with an effective data packet on the effective antenna; the location of the first data comprises a location corresponding to the location of the first effective data in the effective data packet; the effective data packet refers to a data packet sent to the terminal by means of the effective antenna; performing transmission power reduction processing on the first data corresponding to the location of the first data in the first data packet, so as to obtain a second data packet; and sending the effective data packet by means of the effective antenna, and sending the second data packet by means of the interference antenna. The present invention is applicable to a scenario where data is sent by means of an antenna.
