    Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting an acknowledgement frame in a wireless local area network. The method includes: generating an acknowledgement frame for a send frame, where the acknowledgement frame includes a short acknowledgement frame, and the short acknowledgement frame includes an STF, an LTF, and a SIG; and sending the acknowledgement frame. In the embodiments of the present invention, the short acknowledgement frame may not include a data unit, so that a size of the acknowledgement frame is reduced and an overhead of the acknowledgement frame is cut down, thereby improving interaction efficiency of the acknowledgement frame.

    Abstract: A communication method and a related apparatus, applied to intelligent driving or assisted driving are described. The method includes a first node sending a message on at least one of M first time domain resources. The first node receives a message on at least one of N second time domain resources. The first time domain resource is used by the first node to send a message. The second time domain resource is used by the first node to receive a message. The M first time domain resources and the N second time domain resources belong to a first transmission opportunity. A time domain resource in the first transmission opportunity is for message transmission on a first frequency hopping channel. M is an integer greater than 0, N is an integer greater than 0, and M+N>2.
