Systems and methods are described that facilitate evaluating conditions of nodes (e.g., access points, access terminals, etc.) in a wireless communication environment having a plurality of carriers to determine a level of disadvantage for a given node relative to other nodes. The node may transmit a resource utilization message (RUM) that represents the level of disadvantage for the node and request other interference nodes to back off on one or more carriers. This would allow frequency reuse if nodes vary the power of transmission for particular carriers, in conjunction with neighboring nodes.

L'invention porte sur des systèmes et des procédés qui facilitent l'évaluation de conditions de nuds (par exemple, des points d'accès, des terminaux d'accès, etc.) dans un environnement de communication sans fil comprenant une pluralité de porteuses pour déterminer un niveau de désavantage pour un nud donné par rapport à d'autres nuds. Le nud peut émettre un message d'utilisation de ressource (RUM) qui représente le niveau de désavantage pour le nud et demander à d'autres nuds brouilleurs de se replier sur une ou plusieurs porteuses. Cela permettrait une réutilisation de fréquence si les nuds font varier la puissance d'émission pour des porteuses particulières, conjointement avec des nuds voisins.
