The UAV preambles can be allocated to different subscription levels, such that each UAV UE device can only use UAV preambles associated with the UAV UE device's subscription level. The UAV UE device transmits random access request message using the selected UAV preamble and the base station responds with a random access response message indicating whether access is granted to the UAV UE device. The base station can dynamically manage access to the base station by limiting the subscription levels that are associated with the UAV preambles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Preamble management for unmanned aerial vehicles","description":"A base station allocates unmanned aerial vehicles (UAVs) preambles for use by UAV user equipment (UE) devices that are different from terrestrial preambles allocated for terrestrial UE devices.
