Abstract:
(EN) The objective of the present invention is to suppress a deterioration in reception quality even if beam forming is used for both transmission and reception. A device according to one mode of embodiment of the present invention includes: a receiving unit which receives beam specifying information indicating a transmission beam; and a control unit which determines a reception beam on the basis of a reception reference signal; characterized in that the control unit acquires a first index relating to correspondence between the transmission beam and the reception beam.
(FR) L'objectif de la présente invention est d'éliminer une détérioration de la qualité de réception même si une formation de faisceau est utilisée pour la transmission et la réception. Un dispositif selon un mode de réalisation de la présente invention comprend : une unité de réception qui reçoit des informations de spécification de faisceau indiquant un faisceau de transmission ; et une unité de commande qui détermine un faisceau de réception sur la base d'un signal de référence de réception ; caractérisé en ce que l'unité de commande acquiert un premier indice relatif à une correspondance entre le faisceau de transmission et le faisceau de réception.
(JA) 送信及び受信の両方にビームフォーミングを用いる場合であっても受信品質の劣化を抑制すること。本発明の一態様に係る装置は、送信ビームを示すビーム特定情報を受信する受信部と、受信参照信号に基づいて受信ビームを決定する制御部と、を有し、前記制御部は、前記送信ビーム及び前記受信ビームの一致に関する第1の指標を取得することを特徴とする。
