Abstract
(EN)  Provided are a communication system, local area base station device, mobile communication terminal and communication method, which can provide highly efficient local-area wireless access. A communication system in which a mobile communication terminal communicates wirelessly, using a first carrier, with a wide area base station device which covers a wide area, and communicates wirelessly, using a second carrier, with a local area base station which covers a local area. The wide area base station device assigns different frequencies for uplink and downlink on the first carrier in communicating with the mobile communication terminal, and the local area base station device dynamically switches between uplink and downlink for each unit of time in the second carrier, on the basis of the communication environment in communicating with the mobile communication terminal.
(FR)  L'invention concerne un système de communication, un dispositif de station de base de zone locale, un terminal de communication mobile, et un procédé de communication qui permettent de fournir un accès sans fil de zone locale extrêmement efficace. L'invention concerne un système de communication dans lequel un terminal de communication mobile communique sans fil, d'une part, au moyen d'une première porteuse, avec un dispositif de station de base de zone étendue qui couvre une zone étendue et communique sans fil, d'autre part, au moyen d'une seconde porteuse, avec une station de base de zone locale qui couvre une zone locale. Le dispositif de station de base de zone locale attribue différentes fréquences pour des liaisons montante et descendante sur la première porteuse en communication avec le terminal de communication mobile, et le dispositif de station de base de zone locale commute de manière dynamique entre les liaisons montante et descendante pour chaque unité de temps de la seconde porteuse, selon l'environnement de communication, lors de la communication avec le terminal de communication mobile.
(JA)  高効率なローカルエリア無線アクセスを提供できる通信システム、ローカルエリア基地局装置、移動端末装置、及び通信方法を提供すること。移動端末装置が、ワイドエリアをカバーするワイドエリア基地局装置との間で第1のキャリアを用いて無線通信すると共に、ローカルエリアをカバーするローカルエリア基地局装置との間で第2のキャリアを用いて無線通信する通信システムであって、ワイドエリア基地局装置は、第1のキャリアで上下リンクに異なる周波数を割り当てて移動端末装置と通信し、ローカルエリア基地局装置は、通信環境に基づいて、第2のキャリアで上下リンクを時間毎に動的に切り替えて移動端末装置と通信する。
