Abstract:
(EN) In order to suppress reductions in system performance even when carrying out communication applying a downlink control channel configuration different from those in existing LTE systems, this user terminal is characterized by being provided with a receiving unit which receives a downlink control channel, and a control unit which controls determination of multiple first radio resources corresponding to multiple downlink control channel candidates in a first aggregation level and controls determination, from said multiple first radio resources, of multiple second radio resources that correspond to multiple downlink control channel candidates in a second aggregation level lower than the first aggregation level.
(FR) La présente invention vise à supprimer des réductions de performance de système même lors de la réalisation d'une communication appliquant une configuration de canal de commande de liaison descendante différente de celle des systèmes LTE existants. À cet effet, l'invention concerne un terminal utilisateur caractérisé en ce qu'il est pourvu d'une unité de réception qui reçoit un canal de commande de liaison descendante, et d'une unité de commande qui commande la détermination de multiples premières ressources radio correspondant à de multiples candidats de canaux de commande de liaison descendante dans un premier niveau d'agrégation et qui commande la détermination, parmi lesdites multiples premières ressources radio, de multiples secondes ressources radio qui correspondent à de multiples candidats de canaux de commande de liaison descendante dans un second niveau d'agrégation inférieur au premier niveau d'agrégation.
(JA) 既存のLTEシステムと異なる下り制御チャネルの構成を適用して通信を行う場合であっても、システム性能の低下を抑制するために、ユーザ端末は、下り制御チャネルを受信する受信部と、第1アグリゲーションレベルにおける複数の下り制御チャネル候補にそれぞれ対応する複数の第1無線リソースの決定を制御し、前記複数の第1無線リソースのうち、前記第1アグリゲーションレベルよりも低い第2アグリゲーションレベルにおける複数の下り制御チャネル候補にそれぞれ対応する複数の第2無線リソースの決定を制御する制御部と、を有することを特徴とする。
