Abstract: A data feedback method includes acquiring, by the beamformee, the number of columns from a null data packet announcement (NDPA) message; detecting the number of active first spatial streams; comparing the number of first spatial streams with the number of columns, and taking the smaller value obtained from the comparison as the number of second spatial streams required for feedback; and feeding back the number of second spatial streams and spatial stream measurement information about the second spatial streams to the beamformer.

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.
