Title (EN) USER DEVICE AND PREAMBLE TRANSMISSION METHOD
(FR) DISPOSITIF D'UTILISATEUR ET PROCÉDÉ DE TRANSMISSION DE PRÉAMBULE
(JA) ユーザ装置、及びプリアンブル送信方法
Abstract:
(EN) In the present invention, a wireless communication system has a base station and a user device. The user device is provided with: a reception unit that receives a plurality of prescribed signals transmitted through a plurality of beams from the base station; and a transmission unit that transmits a preamble by using a resource corresponding to at least one of the beams, wherein the reception unit measures reception quality in each of the beams, and the transmission unit transmits the preamble by using a resource corresponding to a beam of reception quality that satisfies a prescribed condition.
(FR) Dans la présente invention, un système de communication sans fil comprend une station de base et un dispositif d'utilisateur. Le dispositif d'utilisateur comporte : une unité de réception qui reçoit une pluralité de signaux recommandés transmis par l'intermédiaire d'une pluralité de faisceaux en provenance de la station de base ; et une unité de transmission qui transmet un préambule en utilisant une ressource correspondant à au moins l'un des faisceaux, l'unité de réception mesurant la qualité de réception dans chacun des faisceaux, et l'unité de transmission transmettant le préambule en utilisant une ressource correspondant à un faisceau de qualité de réception qui satisfait une condition recommandée.
(JA) 基地局とユーザ装置とを有する無線通信システムにおける前記ユーザ装置において、前記基地局から、複数のビームにより送信される複数の所定の信号を受信する受信部と、前記複数のビームのうちの少なくとも1つのビームに対応するリソースを用いてプリアンブルを送信する送信部と、を備え、前記受信部は、前記複数のビームのそれぞれにおける受信品質を測定し、前記送信部は、所定の条件を満たす受信品質のビームに対応するリソースを用いてプリアンブルを送信する。
