Title (EN) USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD
(FR) TERMINAL UTILISATEUR, STATION DE BASE SANS FIL ET PROCÉDÉ DE COMMUNICATION SANS FIL

Abstract:
(EN) The present invention enables communication to be performed by using an uplink shared channel that has a configuration suitable for short TTIs. A user terminal according to the present invention sets short TTIs so as to include one of two symbols in which demodulation reference signals for a normal-TTI uplink shared channel are transmitted. In the short TTIs, the user terminal transmits the uplink shared channel and transmits a demodulation reference signal for the short-TTI uplink shared channel in the one symbol.
(FR) La présente invention permet à une communication d’être réalisée par utilisation d’un canal partagé de liaison montante qui a une configuration appropriée pour des intervalles de temps d'émission (TTI) courts. Un terminal utilisateur, selon la présente invention, règle des TTI courts de façon à comprendre l’un de deux symboles dans lesquels des signaux de référence de démodulation pour un canal partagé de liaison montante à TTI normal sont émis. Dans les TTI courts, le terminal utilisateur émet le canal partagé de liaison montante et émet un signal de référence de démodulation pour le canal partagé de liaison montante à TTI court dans ledit symbole.
(JA) 短縮TTIに適する構成の上り共有チャネルを用いて通信を行うこと。本発明のユーザ端末は、通常TTIの上り共有チャネルの復調用参照信号が送信される2シンボルの一つを含むように短縮TTIを設定する。当該ユーザ端末は、当該短縮TTIにおいて上り共有チャネルを送信するとともに、上記1シンボルで上記短縮TTIの上り共有チャネルの復調用参照信号を送信する。
