Abstract

La présente invention concerne un procédé de transmission d'informations, un dispositif terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un dispositif terminal détermine un premier message, le premier message comprenant un premier champ et un second champ, le premier champ comprenant un rapport d'état de tampon (BSR) d'un groupe de canaux logiques à transmettre, le second champ comprenant un premier sous-champ, le premier sous-champ étant utilisé pour indiquer le type du BSR, et si le BSR est un BSR de type tronqué, le premier sous-champ lorsque le premier champ comprend un BSR d'un groupe de canaux logiques étant identique au premier sous-champ lorsque le premier champ comprend des BSR de multiples groupes de canaux logiques ; et le dispositif terminal envoie le premier message au dispositif de réseau. En conséquence, si un BSR rapporté par le dispositif terminal est un BSR tronqué, un même LCID peut être utilisé lorsque le dispositif terminal rapporte un BSR d'un canal logique ou signale des BSR de multiples canaux logiques, réduisant ainsi les surdébits binaires du LCID.
