(EN) METHOD AND APPARATUS FOR SUPPORTING POWER SHARING AND CONTROL BETWEEN IAB LINKS IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR LA PRISE EN CHARGE D'UN PARTAGE ET D'UN CONTRÔLE D'ÉNERGIE ENTRE DES LIAISONS IAB DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A method and apparatus for supporting power sharing and/or control between integrated access and backhaul (IAB) links in a wireless communication system is provided. When a first node (e.g., IAB node) performs a downlink (DL) transmission to a wireless device (e.g., user equipment (UE)) based on a DL resource and an uplink (UL) transmission to a second node (e.g., another IAB node and/or donor node) based on a UL resource at a same time interval, the DL resource and the UL resource are separated by at least one guard physical resource block (PRB) in a frequency domain.
(FR)
L'invention concerne un procédé et un appareil pour la prise en charge d'un partage et/ou d'un contrôle d'énergie entre des liaison d'accès et de raccordement intégrées (IAB) dans un système de communication sans fil. Lorsqu'un premier nœud (un nœud IAB, par ex.) exécute une transmission de liaison descendante (DL) à destination d’un dispositif sans fil (un équipement utilisateur (UE), par ex.) sur la base d'une ressource DL, et exécute une transmission de liaison montante (UL) à destination d’un second nœud (un autre nœud IAB et/ou un nœud donneur, par ex.) sur la base d'une ressource UL, à un même intervalle de temps, la ressource DL et la ressource UL sont séparées par au moins un bloc de ressources physiques (PRB) de garde dans un domaine fréquentiel.
