In the method, an AP sends a radio frame to multiple STAs associated with the AP, wherein the radio frame carries an indication field, and the indication field is used to indicate whether the radio frame carries traffic indication virtual bitmap information. According to the technical solution provided, in the case where the AP has no unicast cache data for any station, multiple STAs associated with the AP can know whether the AP has their respective unicast cache data to be sent."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for sending traffic indication information","description":"Provided are a method and a device for sending traffic indication information.
