Abstract

La présente invention concerne un procédé et un appareil de communication. Le procédé permet à un dispositif de réseau de configurer un terminal, de telle sorte que le terminal, lors de la réalisation d'une transmission de données, effectue une adaptation de débit sur des SSB dans un groupe SSB cible. Étant donné que les SSB dans le groupe SSB cible sont une partie de tous les SSB du dispositif de réseau, le terminal a seulement besoin d'effectuer une adaptation de débit sur une partie de tous les SSB, réduisant ainsi les surcharges de transmission et réduisant le gaspillage de ressources temps-fréquence.
