Disclosed is a method for allocating resources in a base station of a wireless communication system that performs communication using frequency resources. The method includes dividing subcarriers into subcarrier sets each including a predetermined number of consecutive subcarriers, and generating a resource index table mapped to consecutive indexes such that a distance between subcarriers in the subcarrier sets is maximized; and determining an amount of resources to be transmitted through a downlink according to a channel condition, for data to be transmitted to each terminal, and allocating resources to the terminal using the index value in the resource index table.

La présente invention concerne un procédé pour attribuer des ressources dans une station de base d'un système de communication sans fil qui réalise des communications à l'aide de ressources de fréquence. Le procédé comprend la division des sous-porteuses en ensembles de sous-porteuses comprenant chacun un nombre prédéterminé de sous-porteuses consécutives et la génération d'un tableau d'indice de ressources renvoyant aux indices consécutifs de sorte que la distance soit maximisée entre les sous-porteuses dans les ensembles de sous-porteuses; et la détermination d'une quantité de ressources à transmettre à travers une liaison descendante en fonction de l'état d'un canal, pour les données à transmettre à chaque terminal, et l'attribution de ressources au terminal à l'aide de la valeur d'indice dans le tableau d'indice de ressources.
