Abstract
(EN) This base station is provided with: a control unit (11) which, when transmitting to terminals present in a service area of the base station a plurality of signals common to each terminal, performs control to transmit the plurality of signals to the terminals present in the service area by setting the transmission timing of the plurality of signals to the same timing, frequency multiplexing the plurality of signals on the frequency axis, in an area, within the service area, to which simultaneous transmission is possible using a beam, and transmitting the plurality of signals multiple times while changing the area; and an antenna unit (14) which transmits the plurality of signals on an area by area basis, with the direction of the beam changed by means of the control performed by the control unit (11).
(FR) L'invention concerne une station de base qui est pourvue : d'une unité de commande (11) qui, lors de la transmission à des terminaux présents dans une zone de service de la station de base, une pluralité de signaux communs à chaque terminal, effectue une commande pour transmettre la pluralité de signaux aux terminaux présents dans la zone de service en réglant la synchronisation de transmission de la pluralité de signaux à la même synchronisation, en multiplexant en fréquence la pluralité de signaux sur l'axe de fréquence, dans une zone, à l'intérieur de la zone de service, à laquelle une transmission simultanée est possible à l'aide d'un faisceau, et en transmettant la pluralité de signaux multiples fois tout en changeant la zone ; et d'une unité d'antenne (14) qui transmet la pluralité de signaux sur une base de zone par zone, la direction du faisceau étant modifiée au moyen de la commande effectuée par l'unité de commande (11).
(JA) 自基地局のサービスエリアに存在する端末に対して各端末に共通な複数の信号を送信する場合、サービスエリアのうち、ビームを使用して同時に送信が可能なエリアにおいて、複数の信号の送信タイミングを同一タイミングとし、かつ、周波数軸上で複数の信号を周波数多重し、エリアを変えながら複数の信号を複数回送信することでサービスエリアに存在する端末に複数の信号を送信する制御を行う制御部(11)と、制御部(11)の制御によりビームの方向を変えて、エリア単位で複数の信号を送信するアンテナ部(14)と、を備える。
