Abstract

La présente divulgation se rapporte au domaine technique des communications et concerne en particulier un procédé et un appareil d'envoi d'informations, un procédé et un appareil de réception d'informations, un terminal, un dispositif de réseau aérien et un dispositif de réseau au sol. Le procédé d'envoi d'informations consiste à : envoyer des informations de liaison montante et des premières informations auxiliaires à un premier dispositif de réseau aérien, les premières informations auxiliaires étant utilisées pour indiquer si un terminal s'attend à recevoir des informations de liaison descendante correspondant aux informations de liaison montante. Sur la base de la présente divulgation, un terminal envoie des premières informations auxiliaires à un premier dispositif de réseau aérien, permettant au premier dispositif de réseau aérien de déterminer si le terminal s'attend à recevoir des informations de liaison descendante correspondant à des informations de liaison montante, de sorte que le premier dispositif de réseau aérien effectue une opération appropriée, ce qui aide à améliorer des problèmes tels qu'un délai de communication et le gaspillage de ressources de communication.
