Abstract:
(EN) The objective of the present invention is to perform a random access procedure in communication employing beam forming appropriately in a future wireless communication system. This user equipment is characterized in comprising: a receiving unit which receives a DL signal transmitted from a radio base station; a transmitting unit which transmits a UL signal in a random access procedure; and a control unit which controls transmission by applying beam forming to the UL signal; wherein the control unit controls the transmission using at least one beam applied to the UL signal on the basis of the DL signal, and/or the transmission timing.
(FR) L'objectif de la présente invention est d'effectuer une procédure d'accès aléatoire lors d'une communication à l'aide d'une formation de faisceau appropriée dans un futur système de communication sans fil. L'équipement utilisateur selon l'invention est caractérisé en ce qu'il comprend : une unité de réception qui reçoit un signal DL émis à partir d'une station de base radio; une unité d'émission qui émet un signal UL dans une procédure d'accès aléatoire; et une unité de commande qui commande l'émission en appliquant une formation de faisceau sur le signal UL; l'unité de commande commandant l'émission à l'aide d'au moins un faisceau appliqué sur le signal UL sur la base du signal DL et/ou de la synchronisation de transmission.
(JA) 将来の無線通信システムにおいて、ビームフォーミングを用いる通信において、ランダムアクセス手順を適切に行うこと。本発明のユーザ端末は、無線基地局から送信されるDL信号を受信する受信部と、ランダムアクセス手順においてUL信号を送信する送信部と、前記UL信号にビームフォーミングを適用して送信を制御する制御部と、を有し、前記制御部は、前記DL信号に基づいて前記UL信号に適用する少なくとも1つのビーム及び/又は送信タイミングを利用して送信を制御することを特徴とする。
