Abstract

Selon certains modes de réalisation, la présente invention concerne des procédés et un appareil d'émission et de réception de données. Le procédé d'émission de données consiste : à obtenir, par un dispositif terminal, une première autorisation ou une première ressource ; à déterminer une seconde autorisation ou une seconde ressource selon la première autorisation ou la première ressource ; et à transmettre les données à l'aide de la seconde autorisation ou de la seconde ressource. Par conséquent, des exigences de latence ou des exigences de débit binaire pour un ou plusieurs types de services ou de données dans un dispositif terminal peuvent être satisfaites.
