Systems and methodologies are described that facilitate resolving resource assignment conflicts between access terminals in a wireless communication environment. A first access terminal may receive a persistent, or "sticky" assignment of a set of resources (i.e. a permanent assignment of a resource, which means allocated for an unlimited time period), such as subcarriers . In the event that a second access terminal requires a brief resource assignment, a time-limited, or "non-sticky" resource assignment may be granted to the second access terminal (i.e. to be assigned/allocated for a limited time period). If a resource in the non-sticky assignment is already assigned to the first access terminal via the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender (yield, relinquish) the conflicted resource for a limited duration time, and may resume control over the conflicted resource after the termination of the non-sticky assignment.

Systèmes et procédés facilitant la résolution de conflits d'attribution des ressources entre terminaux d'accès dans un environnement de communications sans fil. Un premier terminal d'accès peut recevoir une attribution persistante ou <=fidèle >= d'ensemble de ressources, du type sous-porteuses. Si un second terminal d'accès nécessite une attribution de ressources brève, on peut procéder à une attribution brève, limitée dans le temps, ou non <= fidèle >= au second terminal d'accès. Si une ressource de cette attribution est déjà attribuée au premier terminal d'accès via l'attribution fidèle, le premier terminal d'accès peut recevoir une indication de conflit avec l'information liée à une durée de l'attribution non fidèle, peut remettre la ressource faisant l'objet du conflit et peut reprendre le contrôle sur cette ressource après la fin de l'attribution non fidèle.
