Title (EN) USER TERMINAL, RADIO BASE STATION AND RADIO COMMUNICATION METHOD
(FR) TERMINAL UTILISATEUR, STATION DE BASE RADIO ET PROCÉDÉ DE RADIOCOMMUNICATION
(JA) ユーザ端末、無線基地局及び無線通信方法
Abstract:
(EN) The problem addressed by the present invention is to communicate using a radio interface with improved expandability in a frequency domain. In the present invention, a user terminal is equipped with a receiving unit that receives a downlink control signal containing assignment information for a downlink data signal, and that receives said downlink data signal on the basis of said downlink control signal, and a transmission unit that transmits an uplink control signal containing delivery verification information for said downlink data signal. In addition, a plurality of domain units are formed in which the entire frequency bandwidth is blocked. The aforementioned downlink control signal, the aforementioned downlink data signal and the aforementioned uplink control signal are time-multiplexed within the same frequency domain unit.
(FR) L'objectif de cette invention est de communiquer à l'aide d'une interface radio à extensibilité améliorée dans un domaine de fréquence. Dans la présente invention, un terminal utilisateur comprend une unité de réception qui reçoit un signal de commande descendant contenant des informations d'affectation concernant un signal de données descendant, et qui reçoit ledit signal de données descendant sur la base dudit signal de commande descendant, et une unité de transmission qui transmet un signal de commande montant contenant des informations de vérification de distribution concernant ledit signal de données descendant. De plus, une pluralité d'unités de domaine sont formées dans lesquelles la totalité de la largeur de bande de fréquences est bloquée. Le signal de commande descendant précité, le signal de données descendant précité et le signal de commande montant précité sont soumis à un multiplexage temporel dans la même unité de domaine de fréquence.
(JA) 周波数領域における拡張性を向上させた無線インターフェースを用いて通信すること。本発明において、ユーザ端末は、下りデータ信号の割り当て情報を含む下り制御信号を受信し、当該下り制御信号に基づいて当該下りデータ信号を受信する受信部と、当該下りデータ信号の送達確認情報を含む上り制御信号を送信する送信部と、を具備する。また、全体の周波数帯域がブロック化された複数の周波数領域単位が形成される。上記下り制御信号と上記下りデータ信号と上記上り制御信号とが、同一の周波数領域単位内で時分割多重される。
