(JA) 移動体通信システム
Abstract
(EN)
A mobile communication system, in which a mobile communication terminal (200) simultaneously communicates with a plurality of mobile communication base stations (100) via a multicarrier wireless communication scheme, comprises an upstream channel quality determining part (108) that determines channel quality information of a subcarrier between the mobile communication terminal (200) and each of the mobile communication base stations (100); and a subcarrier assignment deciding part (16) that decides, based on the determined channel quality information of the subcarrier, a subcarrier assignment for each of the mobile communication base stations (100).
(FR)
La présente invention concerne un système de communication mobile, dans lequel un terminal de communication mobile (20) communique simultanément avec une pluralité de stations de base de communication mobile (100) via un principe de communication sans fil à porteuses multiples, qui comprend une partie de détermination de qualité du canal amont (108) qui détermine l'information de qualité du canal d'une sous-porteuse entre le terminal de communication mobile (200) et chacune des station de base de communication mobile (100); et une partie de décision d'attribution de sous-porteuse (16) qui décide, en fonction de l'information de qualité du canal déterminée de la sous-porteuse, une attribution de sous-porteuse pour chacune des stations de base de communication mobile (100).
(JA)
 この発明に係る移動体通信システムは、マルチキャリア無線通信方式で移動体通信端末200が複数の移動体通信基地局100と同時に通信するもので、移動体通信基地局100と移動体通信端末200間のサブキャリアの回線品質情報を測定する上り回線品質測定部108と、測定されたサブキャリアの回線品質情報に基づき、移動体通信基地局100毎にサブキャリアの割り当てを決定するサブキャリア割当決定部16とを備えたものである。
