Abstract:
(EN) The purpose of the present invention is to appropriately control transmission (including retransmission) and/or reception of a transport block (TB) base and/or a code block group (CBG) base. A user terminal according to one embodiment of the present invention is provided with: a reception unit which, if a CBG configured from at least one code block (CB) is to be retransmitted, receives downlink control information (DCI) that is used for scheduling of the CBG; and a control unit which controls reception of the CBG on the basis of the DCI. The control unit controls decoding of the CBG on the basis of the cause of the retransmission of the CBG.
(FR) La présente invention a pour objet de commander de façon appropriée l'émission (y compris la réémission) et/ou la réception d'une base de blocs de transport (TB) et/ou d'une base de groupe de blocs de code (CBG). Un terminal d'utilisateur selon un mode de réalisation de la présente invention comporte: une unité de réception qui, si un CBG constitué d'au moins un bloc de code (CB) doit être réémis, reçoit des informations de commande de liaison descendante (DCI) qui sont utilisées pour la programmation du CBG; et une unité de commande qui commande la réception du CBG d'après les DCI. L'unité de commande assure la commande du décodage du CBG en fonction de la cause de la réémission du CBG.
(JA) トランスポートブロック(TB)ベース及び/又はコードブロックグループ(CBG)ベースの送信(再送を含む)及び/又は受信を適切に制御すること。本発明の一態様に係るユーザ端末は、一以上のコードブロック(CB)で構成されるCBGが再送される場合、前記CBGのスケジューリングに用いられる下りリンク制御情報(DCI)を受信する受信部と、前記DCIに基づいて、前記CBGの受信を制御する制御部と、を具備し、前記制御部は、前記CBGの再送原因に基づいて、前記CBGの復号を制御する。
