The method includes: monitoring, by a first station in a sleep state, a beacon frame broadcast by an access point AP, setting up a direct link with a second station when it is determined that the beacon frame has a buffer information indication indicating that the second station needs to transmit data, and then receiving the data transmitted by the second station. The method and the device disclosed in the present invention aim to solve a problem of larger signaling overheads during setup of an existing D2D direct link."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device and system for device to device D2D data transmission","description":"The present invention discloses a method, a device and a system for device to device D2D data transmission.
