Abstract
Embodiments of this application disclose a spatial reuse indication method and a wireless communications apparatus, thereby reducing a quantity of nodes that can participate in spatial reuse, reducing mutual interference between nodes in spatial reuse, and improving spatial reuse system performance. The method in some implementations includes a first access point generates a spatial reuse limitation indication and a spatial reuse group indication. The spatial reuse limitation indication can be used to indicate whether only a node in a spatial reuse group is allowed for spatial reuse and to indicate the spatial reuse group. The spatial reuse group includes one or more basic service sets. The first access point sends the spatial reuse limitation indication and the spatial reuse group indication.
