Each data communication in said system between the control station and a drone taking place in the form of packets, each packet comprising a preamble and being transmitted in a form modulated according to a predefined modulation. The method comprises: using, in each packet communication from the control station to a drone, a so-called uplink preamble, orthogonal to the so-called downlink preamble, used in each packet communication from a drone to the control station; and, on reception of a modulated packet, determining whether said modulated packet has been transmitted in the context of an uplink or downlink communication according to a result of a convolution between said modulated packet with a reference preamble modulated according to the predefined modulation, said reference preamble corresponding to the uplink preamble or to the downlink preamble."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for distinguishing uplink and downlink communications","description":"Method implemented in a system comprising a control station and at least one drone.
