Title (EN) USER TERMINAL AND WIRELESS COMMUNICATION METHOD
(FR) TERMINAL D’UTILISATEUR ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) The present invention suitably prevents reductions to throughput in communication which uses beamforming. A user terminal according to one embodiment of the present invention is characterized by being provided with a control unit for controlling formation of a beam to be used in the transmission of an uplink signal, and a transmission unit for transmitting information pertaining to the properties of a transceiver, and in that after transmission of the information pertaining to the transceiver properties, the control unit determines whether or not to carry out formation of the beam on the basis of either downlink propagation channel information or uplink propagation channel information.
(FR) La présente invention empêche de manière appropriée des réductions de débit dans des communications qui utilisent la formation de faisceau. Un terminal d’utilisateur selon un mode de réalisation de la présente invention est caractérisé en ce qu’il est équipé d’une unité de commande pour commander la formation d’un faisceau à utiliser dans la transmission d’un signal de liaison montante, et d’une unité de transmission pour transmettre des informations se rapportant aux propriétés d’un émetteur-récepteur, et en ce que, après la transmission des informations se rapportant aux propriétés de l’émetteur-récepteur, l’unité de commande détermine s’il faut exécuter une formation du faisceau en se basant soit sur des informations de canal de propagation en liaison descendante soit sur des informations de canal de propagation en liaison montante.
(JA) ビームフォーミングを用いる通信において、スループットの低下を好適に抑制すること。本発明の一態様に係るユーザ端末は、上り信号の送信に利用するビームの形成を制御する制御部と、送受信機の特性に関する情報を送信する送信部と、を有し、前記制御部は、前記送受信機の特性に関する情報の送信後、下り伝搬路情報及び上り伝搬路情報のいずれに基づいて前記ビームを形成するかを判断することを特徴とする。
