1. A spatial reuse method, comprising:
generating, by a first access point (AP), a radio frame that comprises identification information, wherein the identification information configures a spatial reuse transmission opportunity for a second AP to perform data transmission, and enables the second AP to send a downlink frame to at least one second station (STA) associated with the second AP during an uplink data transmission performed by at least one first station (STA) associated with the first AP; and
sending, by the first AP, the radio frame to the second AP.
