Abstract:
(EN) The purpose of the present invention is to appropriately transmit a scheduling request, a random access preamble, and a sounding reference signal when single UL transmission is adopted in a non-stand-alone radio communication system. The user equipment controls transmission of at least one from among a scheduling request, a random access preamble, and a sounding reference signal in a first RAT on the basis of at least UL/DL configuration.
(FR) La présente invention vise à permettre la transmission appropriée d'une demande de programmation, d'un préambule d'accès aléatoire, et d'un signal de référence de sondage, lorsqu'une transmission UL unique est adoptée dans un système de communication radio non autonome. L'équipement d'utilisateur commande la transmission d'au moins un d'une demande de programmation, d'un préambule d'accès aléatoire, et d'un signal de référence de sondage, dans une première RAT, sur la base d'au moins une configuration UL/DL.
(JA) 非スタンドアローン型の無線通信システムにおいて、シングルUL伝送が適用された場合にスケジューリングリクエスト、ランダムアクセスプリアンブル及びサウンディング参照信号を適切に送信すること。ユーザ端末は、少なくともUL/DL構成に基づいて第1のRATにおけるスケジューリングリクエスト、ランダムアクセスプリアンブル及びサウンディング参照信号の少なくとも一つの送信を制御する。
