Title: DATA TRANSMISSION METHOD AND APPARATUS
Abstract:
Embodiments of the present invention provide a data transmission method and apparatus. The method comprises: a first node sends a first frame to a second node in a full-duplex contention-free transmission opportunity, the first frame comprising first instruction information, and the first instruction information being used for instructing the second node to continue to receive a next frame sent by the first node after a current frame, until after the second frame is received, send first acknowledgment frame corresponding to the first frame to the first node; the first node sends the second frame; and after sending the second frame, the first node receives the first acknowledgment frame sent by the second node. In the embodiments of the present invention, when communication is simultaneously performed between a node and two different nodes, a conflict is avoided on the transmission of an acknowledgment frame, and the bandwidth resource utilization rate is improved, thereby improving the network throughput.
