    Abstract: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

    Abstract: This application provides a channel access method and an apparatus, and relates to the field of communication technologies, to resolve a problem that it is difficult for a long range communication device to access a channel, and communication efficiency is low. The method includes: A first device detects a channel status in first duration. If a channel is in an idle state, M is subtracted from a value of a first counter, where M is a positive integer greater than 1. If the value of the first counter is greater than 0, the first device detects the channel status in next first duration; or if the value of the first counter is less than or equal to 0, the first device transmits data through the channel.

    Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.
