Abstract: This application relates to the field of communication technologies, and specifically, to a data transmission method and apparatus. One example method includes: receiving, by a controller, a performance parameter sent by each of the access points, wherein the performance parameter indicates communication performance between the access point that sends the performance parameter and a first station; determining, by the controller based on each received performance parameter, an access point set configured to provide a data transmission service for the first station, wherein the access point set comprises at least one of the plurality of access points; and when the access point set comprises at least two access points, determining, by the controller, a data transmission mode between each of the access points in the access point set and the first station based on the performance parameter sent by each of the access points in the access point set.

Abstract: A data transmission method and a communication apparatus to improve transmission timeliness. In a wireless local area network, one channel transmission opportunity is obtained by an access point AP through contention. The AP sends service data to a station STA, and the STA feeds back a first data frame in which an error occurs in the service data to the AP. The AP sends scheduling information on a downlink channel to notify the STA of a retransmission resource unit used for retransmission of the first data frame, and retransmits the first data frame on the retransmission resource unit. Correspondingly, the STA receives the first data frame on the retransmission resource unit.
