Abstract: An interference information detection method and a related apparatus are disclosed. The method includes: A server collects information about the plurality of frames from the plurality of stations, where information about some of the plurality of frames includes sending time, contention time, and frame duration, and the contention time indicates time at which a corresponding frame starts to wait to be sent or duration in which the corresponding frame waits to be sent; and the server determines the interference information about the plurality of stations based on the information about the plurality of frames.

Abstract: A method for replying with an acknowledgement frame includes: calculating, by an access point (AP), sending duration of a physical layer service data unit (PSDU) in a to-be-sent downlink physical layer protocol data unit (downlink PPDU) based on a format and a sending rate that are of the downlink PPDU and based on only that a length of each block acknowledgement bitmap field in a block acknowledgement frame in the downlink PPDU is a maximum quantity of bytes that is of each respective block acknowledgement bitmap field of the plurality of stations (STAs), to generate an legacy signal field of a second preamble; and generating, by the AP, the block acknowledgement frame, where each STA information subfield in a block acknowledgement information field of the block acknowledgement frame includes an association identifier traffic identifier field, a block acknowledgement starting sequence control field, and a block acknowledgement bitmap field.
