Title
(EN) KEY MANAGEMENT FOR UE-TO-NETWORK RELAY ACCESS
(FR) GESTION DES CLÉS POUR L'ACCÈS RELAIS UE-À-RÉSEAU
Abstract
(EN) A method of operating a user equipment, UE, (1000) in a wireless communication system is provided. The method includes obtaining (502) a discovery key for discovery of a UE-to-Network relay from a first application function. The method includes using (504) the discovery key for discovery of the UE-to-Network relay over a PC5 interface. A method of operating a user equipment-to-network, UE-to-NW, relay node in a wireless communication system is also provided. The method includes obtaining (702) a discovery key for discovery of a user equipment, UE, from a first application function. The method includes using (704) the discovery key for discovery of the UE over a PC5 interface.
(FR) L'invention concerne un procédé de fonctionnement d'un équipement utilisateur, UE, (1000) dans un système de communication sans fil. Le procédé comprend l'obtention (502) d'une clé de découverte pour la découverte d'un relais d'UE à réseau à partir d'une première fonction d'application. Le procédé comprend l'utilisation (504) de la clé de découverte pour la découverte du relais UE-réseau sur une interface PC5. L'invention concerne également un procédé de fonctionnement d'un nœud de relais équipement utilisateur-réseau, UE-à-NW, dans un système de communication sans fil. Le procédé comprend l'obtention (702) d'une clé de découverte pour la découverte d'un équipement utilisateur, UE, à partir d'une première fonction d'application. Le procédé comprend l'utilisation (704) de la clé de découverte pour la découverte de l'UE sur une interface PC5.
