Title (EN) BASE STATION DEVICE AND COMMUNICATION METHOD
(FR) DISPOSITIF STATION DE BASE ET PROCÉDÉ DE COMMUNICATION
(JA) 基地局装置および通信方法
Abstract:
(EN) This base station device is provided with: a carrier sense unit that carrier-senses a signal observed within a prescribed beam width; and a transmission unit that transmits a data signal through beamforming within the beam width when the carrier-sensing succeeds within the beam width, wherein the carrier-sense unit determines the success or failure on the basis of an energy detection threshold value, and a beam gain of a beam used for the carrier-sensing is taken into consideration for the energy detection threshold value.
(FR) L'invention concerne un dispositif station de base qui comprend : une unité de détection de porteuse qui détecte un signal observé à l'intérieur d'une largeur de faisceau prescrite ; et une unité d'émission qui émet un signal de données par formation de faisceau à l'intérieur de la largeur de faisceau lorsque la détection de porteuse réussit dans la largeur de faisceau, l'unité de détection de porteuse déterminant le succès ou l'échec sur la base d'une valeur seuil de détection d'énergie, et un gain de faisceau d'un faisceau utilisé pour la détection de porteuse étant pris en considération pour la valeur seuil de détection d'énergie.
(JA) 所定のビーム幅で観測した信号をキャリアセンスするキャリアセンス部と、前記ビーム幅でキャリアセンスに成功した場合、前記ビーム幅内のビームフォーミングによってデータ信号を送信する送信部と、を備え、前記キャリアセンス部は、エネルギー検出閾値に基づいて成功又は失敗と判断し、前記エネルギー検出閾値は、前記キャリアセンスに用いたビームのビーム利得が考慮される。
