Method and apparatus for transmitting acknowledgement frame in wireless local area network

摘要

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.

主权项

1. A method applied in a wireless local area network, comprising:
receiving, by a data receiving end, a send frame from a data sending end; generating, by the data receiving end, a short acknowledgement frame for the send frame, the short acknowledgement frame consists of a short training field (STF), a long training field (LTF) and control signaling (SIG) comprising information indicating a duration of a transmit opportunity; and sending, by the data receiving end, the short acknowledgement frame to the data sending end; wherein a length field in the SIG indicates the duration of the transmit opportunity.
