Abstract: Example data transmission methods and apparatus are described. In one example method, a primary device sends a first data packet to a plurality of secondary devices. The primary device separately receives first identification information that is fed back by a respective one of the plurality of secondary devices and that indicates whether a corresponding secondary device successfully receives corresponding first data from the first data packet. The primary device selectively resends the first data packet based on the first identification information.
