The method includes, when a access network device receives downlink data belonging to a first user equipment UE, if it is determined that a supporting UE in a support list of the first UE cannot serve as a current supporting UE of the downlink data, establishing a cooperative communication relationship between a second UE and the first UE, that is, setting the second UE as the current supporting UE of the first UE. The second UE is another UE except the first UE and the supporting UE in the support list of the first UE. The downlink data is sent to the second UE, so that the second UE sends the downlink data to the first UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cooperative communication method and system, access network device, and user equipment","description":"Embodiments of the present invention provide a cooperative communication method and system, an access network device, and a user equipment.
