Title (EN) RADIO BASE STATION APPARATUS AND WIRELESS COMMUNICATION METHOD
(FR) APPAREIL DE STATION DE BASE RADIO ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) 無線基地局装置及び無線通信方法
Abstract:
(EN) Provided are a radio base station apparatus and a wireless communication method wherein even if the number of user-multiplexed upstream control channel signals is increased, the reception characteristic is not degraded.  The wireless communication method comprises: a transmitting step in which at mobile terminal apparatuses, upstream control channel signals, which have been orthogonally multiplexed among the users and include reference signals, are transmitted; a receiving step in which at the radio base station apparatus, the upstream control channel signals are received; and a demodulating step in which the upstream control channel signals are demodulated by use of a maximum likelihood detection.
(FR) La présente invention porte sur un appareil de station de base radio et sur un procédé de communication sans fil, la caractéristique de réception n'étant pas dégradée même si le nombre de signaux de canal de commande de liaison montante multiplexés par un utilisateur. Le procédé de communication sans fil comprend les étapes suivantes : une étape de transmission dans laquelle sont transmis, au niveau des appareils terminaux mobiles, les signaux de canal de commande de liaison montante, qui sont des signaux à multiplexage orthogonal entre les utilisateurs et comprennent des signaux de référence ; une étape de réception dans laquelle sont reçus, au niveau de l'appareil de station de base radio, les signaux de canal de commande de liaison montante ; et une étape de démodulation dans laquelle les signaux de canal de commande de liaison montante sont démodulés à l'aide d'une détection de probabilité maximale.
(JA)  上り制御チャネル信号のユーザ多重数を増加しても、受信特性が劣化しない無線基地局装置及び無線通信方法を提供すること。本発明の無線通信方法は、移動端末装置において、ユーザ間で直交多重した、参照信号を含む上り制御チャネル信号を送信する送信工程と、無線基地局装置において、前記上り制御チャネル信号を受信する受信工程と、前記上り制御チャネル信号に対して最尤検出を用いて復調する復調工程と、を具備することを特徴とする。
