Abstract: This application relates to the wireless communication field, and is applied to a wireless local area network that supports the 802.11be standard. In particular, this application relates to a method including: An access point AP sends a trigger frame, where the trigger frame is used for triggering a station to send an extremely high throughput trigger based physical layer protocol data unit EHT TB PPDU. The station determines, based on one or two of a value indicated by an uplink EHT spatial reuse parameter UL EHT SRP and a value indicated by one or more uplink spatial reuse parameter UL SRP fields in a common information field of the trigger frame, a value indicated by a spatial reuse parameter SRP in a universal signal field U-SIG of the EHT TB PPDU. The STA sends the EHT TB PPDU to the AP.

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: Provided are a spatial reuse method, an apparatus, a device, and a medium. In the method, a first spatial reuse device receives a portion or all of a PSRR PPDU sent by a second spatial reuse device on a first frequency band. The first frequency band includes one or more subbands with a same bandwidth. The first spatial reuse device determines, based on a value of a spatial reuse parameter SRP at a granularity of the bandwidth and a received power level RPL of the PSRR PPDU at a granularity of the bandwidth, a reference transmit power for sending a PSRT PPDU on a second frequency band. The second frequency band includes one or more subbands with the bandwidth. The second frequency band and the first frequency band at least partially overlap.
