Abstract
(EN) A method of sidelink unicast service management in an access stratum layer for a first user equipment (UE) is disclosed. The method comprises receiving, by the first UE through a PC5 interface, a sidelink unicast configuration associated with a second UE, from the second UE, transmitting, by the first UE through a radio resource control, RRC, signaling of the PC5 interface, a sidelink unicast link problem report, to the second UE in responsive to that the first UE is unable to comply with all or part of the sidelink unicast configuration, and performing, by the first UE, a sidelink unicast fallback procedure with the second UE by continuously using a sidelink unicast configuration setting of the first UE with corresponding configurations in a sidelink unicast pre-configuration used prior to the received sidelink unicast configuration.
(FR) L'invention concerne un procédé de gestion de service de monodiffusion de liaison latérale dans une couche de strate d'accès pour un premier équipement utilisateur (UE). Le procédé comprend les étapes suivantes : la réception, par le premier UE à travers une interface PC5, d'une configuration de monodiffusion de liaison latérale associée à un second UE, en provenance du second UE, la transmission, par le premier UE par l'intermédiaire d'une signalisation de commande de ressources radio, RRC de l'interface PC5, d'un rapport de problème de liaison de monodiffusion de liaison latérale, au second UE en réponse à l'incapacité du premier UE à satisfaire tout ou partie de la configuration de monodiffusion de liaison latérale, et l'exécution, par le premier UE, d'une procédure de repli de monodiffusion de liaison latérale avec le second UE en utilisant en continu un réglage de configuration de monodiffusion de liaison latérale du premier UE avec des configurations correspondantes dans une pré-configuration de monodiffusion de liaison latérale utilisée avant la configuration de monodiffusion de liaison latérale reçue.
