Abstract:
(EN) The present invention provides: a communication system and a communication method that can reduce interference between communication terminal devices and increase system capacity, and that can prevent reductions to communication performance that are associated with the movement of a communication terminal device; and a base station device and a communication terminal device that form the communication system. Specifically provided is a communication system, wherein a base station 1001 transmits and receives signals using an array antenna unit 1002 composed of a plurality of antenna elements. The base station 1001 can form a plurality of directional beams having differing beam widths by means of the array antenna unit 1002. The base station 1001 controls the beam widths of the directional beams used in transmitting to and receiving from communication terminals by means of a control unit 1003 and a beam width selection unit 1009, on the basis of feedback information provided from the communication terminals.
(FR) La présente invention concerne : un système de communication et un procédé de communication qui peuvent réduire l'interférence entre des dispositifs terminaux de communication et augmenter une capacité du système, et qui peut empêcher des réductions de performances de communication qui sont associées au mouvement d'un dispositif terminal de communication ; et un dispositif station de base et un dispositif terminal de communication qui forment le système de communication. L'invention concerne spécifiquement un système de communication dans lequel une station de base (1001) émet et reçoit des signaux en utilisant une unité antenne réseau (1002) composée d'une pluralité d'éléments antennes. La station de base (1001) peut former une pluralité de faisceaux directionnels, qui possèdent des largeurs de faisceau différentes, au moyen de l'unité antenne réseau (1002). La station de base (1001) commande les largeurs de faisceau des faisceaux directionnels utilisés pour réaliser des émissions à des terminaux de communication, et des réceptions à partir de ceux-ci, au moyen d'une unité de commande (1003) et d'une unité de sélection de largeur de faisceau (1009), en fonction d'informations de rétroaction fournies par les terminaux de communication.
(JA) 通信端末装置間の干渉を低減して、システム容量を高めるとともに、通信端末装置の移動に伴う通信性能の低下を抑えることができる通信システムおよび通信方法、ならびに前記通信システムを構成する基地局装置および通信端末装置を提供する。通信システムにおいて、基地局1001は、複数のアンテナ素子で構成されるアレーアンテナ部1002を用いて信号の送受信を行う。基地局1001は、アレーアンテナ部1002によって、ビーム幅の異なる複数の指向性ビームを形成可能である。基地局1001は、制御部1003およびビーム幅選択部1009によって、各通信端末から与えられるフィードバック情報に基づいて、各通信端末に対する送受信に用いる指向性ビームのビーム幅を制御する。
