Abstract

Des modes de réalisation de la présente invention concernent le domaine technique des drones, et fournissent un procédé de communication et un dispositif de communication pour un drone, et le drone. Le procédé de communication pour un drone comprend : un premier drone écoute un numéro de canal de fréquence dans une bande de fréquences de signal sans fil; et lorsque le premier drone détecte des premières informations de paramètre au moyen du numéro de canal de fréquence, le premier drone reçoit les premières informations de paramètre, les premières informations de paramètre étant des informations de paramètre d'autres drones dans une plage d'espace aérien où le premier drone est situé; et le premier drone détermine des informations de vol du premier drone selon les premières informations de paramètre. De cette manière, une communication mutuelle parmi de multiples drones peut être mise en œuvre, ce qui permet de réduire les interférences de commande d'un dispositif de commande à distance.
