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 purpose of the present invention is to carry out appropriate transmission power control with respect to various technologies introduced into wireless communication. This user terminal is provided with: a transmission unit which transmits an uplink signal; and a control unit which controls the transmission power of the uplink signal on the basis of a transmission power control (TPC) command included in downlink control information, and/or the reception power of a reference signal that is unique to the user terminal to which downlink beam forming is applied, and/or associated with the downlink beam forming.
(FR) La présente invention a pour objet de réaliser une régulation de puissance d'émission appropriée par rapport à diverses technologies introduites dans une communication sans fil. Le présent terminal d'utilisateur comporte: une unité d'émission qui émet un signal de liaison montante; et une unité de commande qui régule la puissance d'émission du signal de liaison montante selon une consigne de régulation de puissance d'émission (TPC) comprise dans des informations de commande de liaison descendante, et/ou la puissance de réception d'un signal de référence qui est associé de façon unique au terminal d'utilisateur auquel un conformation de faisceau de liaison descendante est appliquée, et/ou associé à la conformation de faisceau de liaison descendante.
(JA) 無線通信において導入される各種技術に対し、適切な送信電力制御を行う。ユーザ端末は、上り信号を送信する送信部と、下りビームフォーミングを適用したユーザ端末固有の、及び/又は、前記下りビームフォーミングに括りつけられた参照信号の受信電力と、下り制御情報に含まれる送信電力制御(TPC)コマンドとの少なくとも一方に基づいて、前記上り信号の送信電力を制御する制御部とを備える。
