(FR) TERMINAL UTILISATEUR ET PROCÉDÉ DE COMMUNICATIONS SANS FIL
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) In order to appropriately control UL grant-free transmissions, this user terminal has: a transmission unit that performs UL grant-free transmissions whereby UL data is sent without UL transmission instructions from a wireless terminal; and a control unit that, on the basis of physical layer signaling, controls changes to parameters used in the UL grant-free transmissions, switching from UL grant-free transmissions to UL grant-based transmissions, and stopping of UL grant-free transmissions.
(FR) L’invention concerne, afin de commander de manière appropriée des transmissions sans octroi de liaison montante, un terminal utilisateur comprenant : une unité de transmission qui effectue des transmissions sans octroi de liaison montante, des données de liaison montante étant envoyées sans instructions de transmission de liaison montante à partir d'un terminal sans fil ; et une unité de commande qui, sur la base d'une signalisation de couche physique, commande les changements de paramètres utilisés dans les transmissions sans octroi de liaison montante, commutant à partir de transmissions sans octroi de liaison montante vers des transmissions basées sur octroi de liaison montante, et arrêtant de transmissions sans octroi de liaison montante.
(JA) ULグラントフリー送信を適切に制御するために、本発明の一態様に係るユーザ端末は、無線基地局からのUL送信指示なしにULデータを送信するULグラントフリー送信を行う送信部と、物理レイヤシグナリングに基づいて、前記ULグラントフリー送信に利用するパラメータの変更、ULグラントフリー送信からULグラントベース送信への切り替え、及びULグラントフリー送信の停止を制御する制御部と、を有する。
