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.
