Title (EN) BASE STATION AND COMMUNICATION METHOD
(FR) STATION DE BASE ET PROCÉDÉ DE COMMUNICATION

Abstract:
(EN) In the present invention, in the case of performing downlink communication with a communication terminal using a downlink wireless resource allocated to the communication terminal at a wireless resource allocation unit, and without the communication terminal transmitting a first known signal using a corresponding uplink wireless resource associated with the downlink wireless resource, the communication terminal transmitting the first known signal using a non-corresponding uplink wireless resource that contains in a frequency direction the frequency band of the downlink wireless resource and that is not associated with the downlink wireless resource, a communication unit controls the transmission directivity of a plurality of antennas on the basis of a second known signal when the communication terminal transmits the second known signal at the frequency band of the downlink wireless resource between the time period of the downlink wireless resource and the time period of the non-corresponding uplink wireless resource.
(FR) Dans la présente invention, dans le cas de l'exécution d'une communication en liaison descendante avec un terminal de communication en utilisant une ressource sans fil en liaison descendante attribuée au terminal de communication au niveau d'une unité d'attribution de ressources sans fil, et sans que le terminal de communication ne transmette un premier signal connu en utilisant une ressource sans fil en liaison montante correspondante associée à la ressource sans fil en liaison descendante, le terminal de communication transmet le premier signal connu en utilisant une ressource sans fil non correspondante en liaison montante qui contient la bande de fréquences de la ressource sans fil en liaison descendante dans une direction de la fréquence et qui n'est pas associée à la ressource sans fil en liaison descendante, une unité de communication contrôle la directivité de transmission d'une pluralité d'antennes sur la base d'un second signal connu lorsque le terminal de communication transmet le second signal connu au niveau de la bande de fréquences de la ressource sans fil en liaison descendante entre la période de temps de la ressource sans fil en liaison descendante et la période de temps de la ressource sans fil non correspondante en liaison montante.
(JA)  通信部は、無線リソース割り当て部において通信端末に対して割り当てられる下り無線リソースを用いて当該通信端末と下り通信を行う場合であって、当該下り無線リソースに対応付けられた対応上り無線リソースを用いて当該通信端末が第1既知信号を送信しておらず、当該下り無線リソースに対応付けられていない、当該下り無線リソースの周波数帯域を周波数方向に含む非対応上り無線リソースを用いて当該通信端末が第1既知信号を送信している場合に、当該下り無線リソースの時間帯と、当該非対応上り無線リソースの時間帯との間において、当該下り無線リソースの周波数帯域で当該通信端末が第2既知信号を送信する際には、当該第2既知信号に基づいて複数のアンテナの送信指向性を制御する。
