Abstract: front page image
(EN)A wireless communication system (1) wherein a radio base station (BS1), which allocates to a radio terminal (UE1) a radio resource specified by the combination of a frequency and a time, and a radio base station (BS2), which allocates to the radio terminal (UE1) the same radio resource, use this radio resource to perform a cooperative communication with the radio terminal (UE1). In the wireless communication system (1), if a predetermined condition, which indicates that the status of the communication between the radio base station (BS2) and the radio terminal (UE1) is good, is satisfied and further if a propagation path quality (Q2) between the radio base station (BS1) and a radio terminal (UE2) is better than a propagation path quality (Q1) between the radio base station (BS1) and the radio terminal (UE1), then the radio base station (BS1) allocates the foregoing radio resource to the radio terminal (UE2) instead of the radio terminal (UE1).
(FR)L'invention concerne un système de communication sans fil (1) dans lequel une station de base radio (BS1), qui alloue à un terminal radio (UE1) une ressource radio spécifiée par la combinaison d'une fréquence et d'un temps, et une station de base radio (BS2), qui alloue au terminal radio (UE1) la même ressource radio, utilisent cette ressource radio pour effectuer une communication coopérative avec le terminal radio (UE1). Dans le système de communication sans fil (1), si une condition prédéfinie, qui indique que l'état de la communication entre la station de base radio (BS2) et le terminal radio (UE1) est bon, est respectée et, en outre, si une qualité de trajet de propagation (Q2) entre la station de base radio (BS1) et un terminal radio (UE2) est meilleure qu'une qualité de trajet de propagation (Q1) entre la station de base radio (BS1) et le terminal radio (UE1), alors la station de base radio (BS1) alloue la ressource radio mentionnée ci-dessus au terminal radio (UE2) à la place du terminal radio (UE1).
(JA) 周波数及び時間の組み合わせにより規定される無線リソースを無線端末UE1に割り当てる無線基地局BS1と、当該無線リソースと同一無線リソースを無線端末UE1に割り当てる無線基地局BS2とが、当該無線リソースを使用して無線端末UE1との協調通信を行う無線通信システム1において、無線基地局BS2と無線端末UE1との通信の状態が良好であることを示す所定の条件が満たされており、且つ、無線基地局BS1と無線端末UE1との間の伝搬路品質Q1よりも、無線基地局BS1と無線端末UE2との間の伝搬路品質Q2が良好である場合、無線基地局BS1は、当該無線リソースを無線端末UE1に代えて無線端末UE2に割り当てる。
