Abstract[English]
Various aspects of the present disclosure relate to enhancing the functionality of a user plane protocol stack, such as by synchronizing or associating certain aspects of a radio link control (RLC) layer and a Packet Data Convergence Protocol (PDCP) layer to one another. For example, the present disclosure introduces a new timer to the RLC layer that starts when the RLC layer triggers a reordering timer in the PDCP layer (e.g., by the RLC later delivering an out of order data packet to the PDCP layer). As another example, the present disclosure enhances user plane transmissions to avoid, mitigate, and/or prevent the transmission/retransmission of outdated packets, such as outdated RLC data units.[French]
Divers aspects de la présente divulgation concernent l'amélioration de la fonctionnalité d'une pile de protocoles de plan utilisateur, par exemple par synchronisation ou association de certains aspects d'une couche de commande de liaison radio (RLC) et d'une couche de protocole de convergence de données par paquets (PDCP) les uns par rapport aux autres. Par exemple, la présente divulgation consiste à introduire un nouveau temporisateur dans la couche RLC qui commence lorsque la couche RLC déclenche un temporisateur de réordonnancement dans la couche PDCP (par exemple, par lorsque la couche RLC délivre ultérieurement un paquet de données hors ordre à la couche PDCP). Dans un autre exemple, la présente divulgation permet d'améliorer les transmissions de plan utilisateur pour éviter, atténuer et/ou empêcher la transmission/retransmission de paquets périmés, tels que des unités de données RLC périmées.
