Abstract
(EN)
Disclosed are methods, systems, apparatus, and computer programs for establishing a data path between an access node and a donor node of an integrated access and backhaul (IAB) network. In one aspect, a method includes selecting a subset of the plurality of nodes to establish the data path, where the subset of nodes includes the access node and one or more intermediate nodes that link the access node to the donor node, and where the one or more intermediate nodes include a final intermediate node that is coupled to the donor node via a donor-node backhaul bearer; establishing an access link bearer that couples a user equipment (UE) to the access node; establishing respective backhaul link bearers between the subset of nodes; and mapping a final one of the respective backhaul link bearers to the donor-node backhaul link bearer.

L'invention concerne des procédés, des systèmes, un appareil et des programmes informatiques permettant d'établir un chemin de données entre un noeud d'accès et un noeud donneur d'un réseau intégré d'accès et de liaison terrestre (IAB). Selon un aspect, le procédé consiste à sélectionner un sous-ensemble de la pluralité des noeuds pour établir le chemin de données, le sous-ensemble de noeuds comprenant le noeud d'accès et un ou plusieurs noeud(s) intermédiaire(s) qui relie(nt) le noeud d'accès au noeud donneur, et le(s) noeud(s) intermédiaire(s) comprenant un noeud intermédiaire final qui est couplé au noeud donneur par l'intermédiaire d'un support de liaison terrestre de noeud donneur ; établir un support de liaison d'accès qui couple un équipement utilisateur (UE) au noeud d'accès ; établir des supports de liaison terrestre respectifs entre le sous-ensemble de noeuds ; et mapper un support final parmi les supports de liaison terrestre respectifs avec le support de liaison terrestre de noeud donneur.
