Title
(EN) RELAY NODE AND A CONTROLLING NODE OF A LTE NETWORK
(FR) NŒUD DE RELAIS ET NŒUD DE COMMANDE DE RÉSEAU LTE
Abstract
(EN) According to various embodiments, a method is provided at a relay node 110 for enabling subframe allocation between a backhaul link 112 and an access link 114 of the relay node 110. The relay node 110 is connected to a controlling entity 120, 140 via the backhaul link 112, and is connectable to at least one user equipment 130 via the access link 114. The relay node receives 410 a trigger or configuration information from the controlling entity from the controlling entity 120, 140. Based on the received trigger or configuration information, the relay node 1 10 sends 420 information to the controlling entity 120, 140, indicating a resource utilization of the access link 114 and/or indicating a quality of the access link 114.
(FR) Selon divers modes de réalisation, l'invention porte sur un procédé au niveau d'un nœud de relais (110) pour permettre une attribution de sous-trame entre une liaison de terrestre (112) et une liaison d'accès (114) du nœud de relais (110). Le nœud de relais (110) est connecté à une entité de commande (120, 140) par la liaison terrestre (112), et peut être connecté à au moins un équipement utilisateur (130) par la liaison d'accès (114). Le nœud de relais reçoit (410) un déclencheur ou des informations de configuration provenant de l'entité de commande (120, 140). Sur la base du déclencheur reçu ou des informations de configuration reçues, le nœud de relais (110) envoie (420) des informations à l'entité de commande (120, 140), indiquant une utilisation de ressources de la liaison d'accès (114) et/ou indiquant une qualité de la liaison d'accès (114).
