Title
(EN) IAB POWER CONTROL
(FR) COMMANDE DE PUISSANCE D'ACCÈS ET DE LIAISON TERRESTRE INTÉGRÉS
Abstract
(EN)
There is disclosed a method of operating an Integrated Access and Backhaul, IAB node (200, C, N3) in a radio access network, the method comprising performing, by the IAB node (200, N1, N2), power control for a first communication link between the IAB node (200, N1, N2) and a power-controlled radio node (10, 200, N3) based on power control information, the power control information pertaining to a second communication link between the power-controlled radio node (10, 200, N3) and a second IAB node (200, N2, N1). The disclosure also pertains to related methods and devices.
(FR)
L'invention concerne un procédé de fonctionnement d'un noeud d'accès et de liaison terrestre intégrés, IAB, (200, C, N3) dans un réseau d'accès radio, le procédé comprenant la réalisation, par le noeud IAB (200, N1, N2), d'une commande de puissance pour une première liaison de communication entre le noeud IAB (200, N1, N2) et un noeud radio commandé en puissance (10, 200, N3) sur la base d'informations de commande de puissance, les informations de commande de puissance se rapportant à une seconde liaison de communication entre le noeud radio commandé en puissance (10, 200, N3) et un second noeud IAB (200, N2, N1). L'invention concerne également des procédés et des dispositifs associés.
