Title (EN) METHOD FOR ADJUSTING INTER-CELL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ DE RÉGLAGE DES INTERFÉRENCES ENTRE CELLULES DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
(KO) 무선 통신 시스템에서 셀들 간의 간섭을 조정하는 방법 및 이를 위한 장치
Abstract: front page image
(EN)According to one embodiment of the present invention, a method by which a fixed base station adjusts inter-cell interference in a wireless communication system comprises the steps of: receiving channel state information - reference signal (CSI-RS) configurations on an access link of each moving cell connected to the fixed base station; determining the CSI-RS configuration on a backhaul link of a first moving cell among the moving cells on the basis of the CSI-RS configurations on the access link; and providing, to the first moving cell, the CSI-RS configuration on the determined backhaul link, wherein the CSI-RS configuration on the determined backhaul link is for measuring, by the backhaul link of the first moving cell, the interference received from an access link of a second moving cell among the moving cells.
(FR)La présente invention concerne, selon un de ses modes de réalisation, un procédé selon lequel une station de base fixe règle les interférences entre cellules dans un système de communication sans fil, comportant les étapes consistant à: recevoir des configurations de signal de référence de données d'état canal (CSI-RS) sur une liaison d'accès de chaque cellule en mouvement reliée à la station de base; déterminer la configuration de CSI-RS sur une liaison de raccordement d'une première cellule en mouvement parmi les cellules en mouvement d'après les configurations de CSI-RS sur la liaison d'accès; et fournir à la première cellule en mouvement la configuration de CSI-RS sur la liaison de raccordement déterminée, la configuration de CSI-RS sur la liaison de raccordement déterminée servant à faire mesurer, par la liaison de raccordement de la première cellule en mouvement, les interférences reçues en provenance d'une liaison d'accès d'une deuxième cellule en mouvement parmi les cellules en mouvement.
(KO)본 발명의 일 실시예에 따른 무선 통신 시스템에서의 고정 기지국이 셀들 간의 간섭을 조정하는 방법은, 상기 고정 기지국에 접속한 이동 셀들 각각의 엑세스 링크 상의 CSI-RS (Channel State Information - Reference Signal) 설정들을 수신하는 단계; 상기 엑세스 링크 상의 CSI-RS 설정들에 기초하여 상기 이동 셀들 중 제1 이동 셀의 백홀 링크 상의 CSI-RS 설정을 결정하는 단계; 및 상기 결정된 백홀 링크 상의 CSI-RS 설정을 상기 제1 이동 셀에 제공하는 단계를 포함하고, 상기 결정된 백홀 링크 상의 CSI-RS 설정은, 상기 제1 이동 셀의 백홀 링크가 상기 이동 셀들 중 제2 이동 셀의 엑세스 링크로부터 받는 간섭을 측정하기 위한 것이다.
