Abstract:
(EN) This user terminal is characterized by being provided with a receiving unit which receives a group common downlink control channel, and a control unit which controls decoding of the group common downlink control channel, wherein the control unit controls the aforementioned decoding under the assumption that the input bit of a polar encoding applied to the aforementioned group common downlink control channel was generated using a method other than a user terminal-specific downlink control channel. By this means, it is possible to suppress the impact of overhead on a group common downlink control channel.
(FR) La présente invention concerne un terminal utilisateur caractérisé en ce qu'il comporte une unité de réception qui reçoit un canal de commande de liaison descendante commun à un groupe, et une unité de commande qui commande le décodage du canal de commande de liaison descendante commun à un groupe, l'unité de commande commandant le décodage susmentionné dans l'hypothèse où le bit d'entrée d'un codage polaire appliqué au canal de commande de liaison descendante commun à un groupe mentionné ci-dessus a été généré par un procédé autre qu'un canal de commande de liaison descendante spécifique à un terminal utilisateur. Ainsi, il est possible de supprimer l'impact du surdébit sur un canal de commande de liaison descendante commun à un groupe.
(JA) 本開示の一態様に係るユーザ端末は、グループ共通下り制御チャネルを受信する受信部と、前記グループ共通下り制御チャネルの復号を制御する制御部と、を有し、前記制御部は、前記グループ共通下り制御チャネルに適用されるポーラー符号化の入力ビットが、ユーザ端末固有下り制御チャネルと異なる方式を用いて生成されたと想定して、前記復号を制御することを特徴とする。本開示の一態様によれば、グループ共通下り制御チャネルについてオーバーヘッドの影響を抑制できる。
