(54) Title (FR): PROCÉDÉ ET APPAREIL DE TRANSMISSION D'UNE UNITÉ DE DONNÉES DANS UN SYSTÈME DE COMMUNICATION SANS FIL

(57) Abstract:
(EN): The present disclosure relates to a method for transmitting a protocol data unit (PDU) by a transmission end in a wireless communication system. In particular, the method includes receiving an uplink (UL) grant from a network; when the UL grant can accommodate all of pending data for a first logical channel but is not sufficient to additionally accommodate a buffer status report (BSR), including the pending data for the first logical channel to the PDU with canceling the BSR; and transmitting the PDU to the network, wherein the UL grant cannot additionally accommodate all of pending data for a second logical channel.
(FR): L'invention concerne un procédé permettant de transmettre une unité de protocole de données (PDU) par une extrémité de transmission dans un système de communication sans fil. En particulier, le procédé comprend la réception d'une autorisation de liaison montante (UL) à partir d'un réseau ; lorsque l'autorisation UL peut recevoir toutes les données en attente pour un premier canal logique mais n'est pas suffisante pour recevoir en plus un rapport d'état de tampon (BSR), l'inclusion des données en attente pour le premier canal logique vers la PDU avec annulation du BSR ; et la transmission de la PDU au réseau, l'autorisation UL ne pouvant pas recevoir en plus toutes les données en attente pour un second canal logique.
