Abstract:
(EN) The present invention reduces interference signals affecting another base station while allowing a base station device to communicate with terminal stations within the area of the base station device in a wireless communication system based on a TDD scheme. In a wireless communication system based on TDD format, a transmission angle control device is provided with: an interference signal detector for detecting, on the basis of a received signal received from a second base station, the level of interference by which a signal transmitted by a first base station affects the second base station, and outputting the level of interference as an interference information signal; and a transmission angle determining unit for adjusting, in accordance with the interference information signal, the angle of transmission of the signal transmitted by the first base station in the vertical direction.
(FR) La présente invention permet de réduire les signaux d'interférence affectant une autre station de base tout en permettant à un dispositif de station de base de communiquer avec des stations de terminaux à l'intérieur de la zone du dispositif de station de base dans un système de communication sans fil basé sur un mécanisme TDD. Dans un système de communication sans fil basé sur un mécanisme TDD, un dispositif de commande d'angle de transmission comporte : un détecteur de signal d'interférence destiné à détecter, sur la base d'un signal reçu en provenance d'une seconde station de base, le niveau d'interférence auquel un signal émis par une première station de base affecte la seconde station de base, et à délivrer en sortie le niveau d'interférence en tant que signal d'informations d'interférence ; et une unité de détermination d'angle de transmission destinée à ajuster, en fonction du signal d'informations d'interférence, l'angle de transmission du signal émis par la première station de base dans la direction verticale.
(JA)  本発明は、TDD方式に基づく無線通信システムにおいて、基地局装置が自身のエリア内における端末局との通信を可能としつつ、他の基地局に与える干渉信号を低減する。送信角度制御装置は、TDD方式に基づく無線通信システムにおいて、第1の基地局が送信する信号が第2の基地局に及ぼす干渉のレベルを、第2の基地局から受信した受信信号に基づいて検出し、干渉情報信号として出力する干渉信号検出部と、干渉情報信号に応じて、第1の基地局が送信する信号の送信角度を垂直方向に調整する送信角度決定部と、を備える。
