After determining to send a BSR to the base station, a specific BSR needs to be generated, which is the operation of generating the BSR described above. However, when UPCON occurs in the uplink direction, the reporting operation of the BSR is controlled based on the priority of the logical channel. Determining whether to trigger the BSR and the generation may result in the base station not being able to properly control the uplink scheduling. Because the data of multiple data types can be multiplexed on one logical channel, the base station and the UE cannot distinguish the data of different data types in one logical channel.
  • data of multiple service flows or applications can be multiplexed on one logical channel for transmission, so that the base station and the UE cannot perform different processing on data of different service flows or different applications, thereby failing to alleviate UPCON in the uplink direction. Therefore, when UPCON occurs in the uplink direction, it is often desirable to differentiate data of different data types, for example, to differentiate different service flows or different applications to ensure data transmission of a certain service flow or application, and suppress Data transmission of certain service flows or applications, such as ensuring voice traffic in video telephony services, suppressing file downloads and email transmissions.

Abstract

Dans des modes de réalisation, la présente invention concerne un procédé de communication, un équipement utilisateur (UE) et une station de base. Le procédé comprend les étapes suivantes : un UE reçoit un message de démarrage de congestion de plan d'utilisateur (UPCON) à partir d'une station de base (210), le message de démarrage d'UPCON étant utilisé pour indiquer qu'une UPCON se produit dans une direction de liaison montante ; l'UE détermine des priorités de multiples types de données sur la base du message de démarrage d'UPCON (220) ; et l'UE commande une opération de rapport d'un rapport d'état de tampon (BSR) sur la base des priorités des multiples types de données (230). Dans les modes de réalisation de la présente invention, les priorités des multiples types de données sont déterminées sur la base du message de démarrage d'UPCON indiquant que la UPCON se produit dans la direction de liaison montante, permettant au BSR d'être déclenché sur la base des priorités des multiples types de données, permettant ainsi à la station de base de commander de manière appropriée une planification de liaison montante sur la base du BSR et d'atténuer la UPCON d'envoi de la direction de liaison montante.
