A receiving station simultaneously receives a plurality of procedure protocol data units (PPDUs) from a sending station on a plurality of channels, where the plurality of PPDUs includes a plurality of media access control protocol data unit (MPDU) sets, and each of the plurality of MPDU sets includes at least a copy of a start MPDU. The receiving station sends a block acknowledgment on one or more channels of the plurality of channels, where the block acknowledgment includes acknowledgment information, and the acknowledgment information indicates acknowledgment of MPDUs successfully received on the plurality of channels and transmission quality of each of the plurality of MPDU sets.

Wireless local area network transmission method and device, and transceiver

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.

Interference information detection method

A communications system is disclosed. The communications system includes a first access point and a second access point whose operating channels overlap. The first access point and the second access point each measure a signal strength of a response frame sent by a terminal device associated with the first access point, to obtain a first signal strength and a second signal strength. The first access point determines, based on the first signal strength and the second signal strength, a power, a power upper limit, or a power adjustment value to be used by the second access point when the second access point and the first access point perform concurrent transmission. The communications system can perform a step of measuring the signal strength in the concurrent transmission between the access points, and reduce dependence on the terminal device.
