摘要： 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.

摘要： A communication method includes that a sharing AP selects a first beam width used to schedule a sharing STA during coordinated transmission, and the sharing AP sends a coordinated transmission notification to a shared AP, where the coordinated transmission notification includes a coordinated transmission parameter, where the coordinated transmission parameter is obtained based on the sharing STA and the first beam width, where the coordinated transmission notification indicates the shared AP to select, based on the coordinated transmission parameter, a shared STA and a second beam width that are used for coordinated transmission, where the second beam width is one of adjustable beam widths of the shared AP, and where the first beam width is one of at least two adjustable beam widths of the sharing AP.

摘要： A method and an apparatus for detecting co-channel interference in a WLAN are provided. The method provided herein includes: A communication device detects a first energy value and a second energy value, where the first energy value is an energy value of a signal on a channel before a WLAN frame is sent, and the second energy value is an energy value of a signal on the channel after the WLAN frame is sent. The communication device determines, based on the first energy value and the second energy value, that the WLAN frame is subject to interference.

摘要： A resource allocation method, a device, and a storage medium are disclosed. The method includes: A network device obtains a packet concurrency status of a plurality of wireless local area network WLAN devices, where the plurality of WLAN devices correspond to a same channel. The network device allocates channel resource slices to the plurality of WLAN devices from a channel resource in a first time period based on the packet concurrency status.
