CA 2573876

To address the need for a resource allocation scheme that results in a better tradeoff between cell-edge performance and overall spectral efficiency, a communication system (100) is provided that allocates uplink transmit power to user equipment (UEs) (102, 104) based on a fractional power control scheme (300). In another embodiment, since the cell-edge users are also likely to be power limited, the communication system may implement a minimized uplink transmission bandwidth resource allocation scheme (404, 406, 408, 410, 412, 414) that may work with the fractional power control scheme to achieve a level of performance desired for uplink transmissions in 3GPP (Third Generation Partnership Project) and 3GPP2 Evolution communication systems.

Afin de répondre au besoin relatif à la mise en place d'un processus d'affectation de ressources qui entraîne un meilleur équilibre entre le rendement en périphérie des cellules et l'efficacité spectrale globale, le système de communication (100) en question affecte la puissance de transmission sens montant au matériel de l'utilisateur (102, 104), selon un processus de régulation de la puissance par fraction (300). Dans un autre scénario, comme les utilisateurs en périphérie des cellules sont en outre susceptibles de voir leur puissance limitée, le système de communication peut mettre en ouvre un processus d'affectation de ressources en bande passante de transmission de liaison montante moindre (404, 406, 408, 410, 412, 414) qui peut fonctionner avec le processus de régulation de la puissance par fraction en vue d'obtenir le rendement désiré pour les transmissions sens montant dans les systèmes de communications 3GPP (Third Generation Partnership Project) et 3GPP2 Evolution.
