Title (EN) METHODS AND APPARATUSES FOR NR PDCP PRESERVATION UPON RRC RESUME/SUSPEND
(FR) PROCÉDÉS ET APPAREILS POUR LA PRÉSERVATION D'UN PDCP NR LORS D'UNE REPRISE/SUSPENSION DE RRC
Abstract:
(EN) A method for use in a user equipment (UE) of resuming a radio bearer in a wireless communication network, which comprises: establishing a radio resource control (RRC) connection with a first network node; receiving a connection suspend message from the first network node; storing a configuration of a radio bearer associated with the RRC connection; suspending the radio bearer associated with the RRC connection; receiving a connection resume message; determining whether the connection resume message includes configuration information for NR packet data convergence protocol (PDCP) for the suspended radio bearer; upon determining the connection resume message includes configuration information for a NR PDCP, configuring the suspended radio bearer with the configuration information; and resuming the suspended radio bearer.
(FR) L'invention concerne un procédé devant être utilisé dans un équipement d'utilisateur (UE) pour la reprise d'un support radio dans un réseau de communication sans fil qui consiste à : établir une connexion de gestion des ressources radio (RRC) avec un premier nœud de réseau; recevoir un message de suspension de connexion, du premier nœud de réseau; stocker une configuration d'un support radio associé à la connexion RRC; suspendre le support radio associé à la connexion RRC; recevoir un message de reprise de connexion; déterminer si le message de reprise de connexion inclut des informations de configuration de protocole de convergence de données de paquet (PDCP) NR pour le support radio suspendu; lorsqu'il est déterminé que le message de reprise de connexion inclut des informations de configuration d'un PDCP NR, configurer le support radio suspendu avec les informations de configuration; et reprendre le support radio suspendu.
