Abstract: front page image
(EN)A multicarrier communication method capable of improving the frequency utilization efficiency and the throughput of the communication system, while satisfying the QoS. A communication terminal reports the CQI about all of the subchannels included in the bandwidth of a communication channel during a first CQI report, as shown in the upper figure portion. Unlike the first report, during the second and following CQI reports, in which much time is left in terms of the permissible delay time, the communication terminal reports the CQI only about subchannels 1 and 2 assigned by the second and following frequency assignments, as shown in the lower figure portion.
(FR)L’invention concerne un procédé de communication multiporteur capable d’améliorer l’efficacité d’utilisation de fréquence et le rendement du système de communication, tout en satisfaisant au QoS. Un terminal de communication signale un CQI concernant tous les canaux auxiliaires inclus dans la largeur de bande d’un canal de communication pendant un premier rapport CQI, comme le montre la portion de figure supérieure. A la différence du premier rapport, pendant le deuxième rapport CQI et les suivants, où il reste beaucoup de temps en termes de temporisation permissible, le terminal de communication signale seulement le CQI concernant les canaux auxiliaires 1 et 2 assignés par la deuxième affectation de fréquence et les suivantes, comme le montre la portion de figure inférieure.
(JA) QoSを満たしつつ周波数利用効率を改善し、通信システムのスループットを向上させることができるマルチキャリア通信方法を開示する。上段に示すように、通信端末は、初回CQI報告時には、通信回線の帯域幅に含まれる全サブチャネルについてCQIを報告する。ところが、2回目以降、許容遅延時間に対する残り時間が多い場合のCQI報告時には、下段に示すように、通信端末は、初回時と異なり、今回の周波数割当によって割り当てられたサブチャネル番号1、2のサブチャネルについてのみCQIを報告する。
