Abstract

La présente invention concerne un procédé de communication, un terminal et un périphérique réseau. Le terminal indique, au moyen de premières informations d'indication dans un rapport d'état de tampon, des groupes de canaux logiques correspondant à au moins deux ressources de tampon à transmettre. En outre, le périphérique réseau peut déterminer les tailles des ressources de tampon de chacun des groupes de canaux logiques correspondant au moins aux deux ressources de tampon à transmettre, ce qui permet d'atteindre l'objectif de rapporter de manière flexible des ressources de tampon d'une certaine quantité de groupes de canaux logiques. Le procédé comprend les étapes suivantes : un terminal envoie un premier message à un périphérique réseau, le premier message comprenant un rapport d'état de tampon, le rapport d'état de tampon comprenant des premières informations d'indication et des informations d'indication des tailles d'au moins deux ressources de tampon à transmettre. Ces ressources tampon à transmettre correspondent à au moins deux groupes de canaux logiques d'une manière biunivoque, et au moins deux groupes de canaux logiques font partie de tous les groupes de canaux logiques du terminal, et les premières informations d'indication sont utilisées pour indiquer les groupes de canaux logiques qui correspondent au moins aux deux ressources de tampon à transmettre.
