Abstract
(EN) The purpose of the present invention is to provide a method for controlling power of an IAB node, and a device using the method. A power control method performed by an IAB node for the purpose comprises: receiving power information, wherein the power information informs the IAB node of a configured power control method; and on the basis that the sum of an MT power for MT transmission and a DU power for DU transmission is greater than the maximum transmission power allocated to the IAB node, performing power control on at least one of the MT power and the DU power on the basis of the power information, wherein an MT resource on which the MT transmission is performed and a DU resource on which the DU transmission is performed overlap in a time domain.
(FR) La présente invention a pour objet de fournir un procédé permettant de commander la puissance d'un nœud IAB et un dispositif utilisant le procédé. Un procédé de commande de puissance réalisé par un nœud IAB dans ce but consiste : à recevoir des informations de puissance, les informations de puissance informant le nœud IAB d'un procédé de commande de puissance configuré ; et, sur la base du fait que la somme d'une puissance MT pour une transmission MT et d'une puissance DU pour une transmission DU est supérieure à la puissance de transmission maximale attribuée au nœud IAB, à réaliser une commande de puissance sur la puissance MT et/ou la puissance DU sur la base des informations de puissance, une ressource MT sur laquelle la transmission MT est réalisée, et une ressource DU sur laquelle la transmission DU est réalisée, se chevauchant dans un domaine temporel.
(KO) 본 발명은 IAB 노드의 전력 제어 방법 및 상기 방법을 이용하는 장치를 제공하기 위한 것이다. 이를 위한 IAB 노드에 의해 수행되는 전력 제어 방법은, 전력 정보를 수신하되, 상기 전력 정보는 상기 IAB 노드에게 설정된 전력 제어 방법을 알려주고, MT 전송에 대한 MT 전력 및 DU 전송에 대한 DU 전력의 합이 상기 IAB 노드에게 할당된 최대 전송 전력보다 큼에 기반하여, 상기 전력 정보에 기반하여 상기 MT 전력 및 상기 DU 전력 중 적어도 하나에 대한 전력 제어를 수행하고, 상기 MT 전송이 수행되는 MT 자원 및 상기 DU 전송이 수행되는 DU 자원은 시간 영역에서 오버랩되는 것을 특징으로 한다.
