Abstract

La présente demande concerne un procédé de communication sans fil et un appareil de communication. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des premières informations d'indication d'un dispositif réseau, les premières informations d'indication indiquant un premier décalage temporel minimal et un second décalage temporel minimal, le premier décalage temporel minimal étant un décalage temporel minimal entre des informations de commande de liaison descendante (DCI) et un canal de données lorsque les DCI transportées sur une première porteuse planifient le canal de données sur la première porteuse, et le second décalage temporel minimal étant un décalage temporel minimal entre les DCI et le canal de données lorsque les DCI transportées sur une seconde porteuse planifient le canal de données sur la première porteuse. La présente invention peut permettre à un dispositif terminal et à un dispositif réseau de parvenir à un consensus sur une porteuse qui applique un décalage temporel minimal, et améliore la fiabilité de la communication.
