1. A data transmission method, wherein the method comprises:
generating, by a transmit end, a data packet;
determining, by the transmit end and based on feedback information transmitted from a receive end, different communications resources for transmission, wherein the feedback information comprises a plurality of indicators, each indicator of the plurality of indicators corresponds to a respective frequency band of a plurality of frequency bands, and an indicator of the plurality of indicators indicates a correspondence between a transmit antenna of the transmit end and a priority of video service data on a corresponding frequency band of the plurality of frequency bands corresponding to the indicator, wherein the indicator of the plurality of indicators is generated based on a power value of the transmit antenna on the corresponding frequency band; and
sending, by the transmit end, the data packet to the receive end, wherein the data packet comprises at least two pieces of video service data having different priorities, and the pieces of video service data having the different priorities are carried on the different communications resources for transmission.
