Traffic scheduling based on resource contention

摘要

In a system where multiple resources are available for carrying traffic, a scheduler may give higher scheduling priority to those resources for which a RUM has been sent. For example, if a node has sent a RUM to reserve a specified carrier of a set of allocated carriers, the scheduler may first attempt to schedule traffic on the specified carrier since there may be less interference on this carrier as a result of the RUM.

1. A method of wireless communication, comprising:
receiving, by an access point, resource utilization messages sent by a first access terminal associated with the access point and sent by second access terminals not associated with the access point, each of the resource utilization messages having a priority and specifying one or more resources that are desired by a respective access terminal for reception of traffic; identifying one or more resources that are specified by the first access terminal; comparing priorities of the received resource utilization messages; making a determination, by the access point, whether the first access terminal has won contention for one or more of the identified one or more resources based on the priorities; and scheduling, by the access point, traffic destined for the first access terminal based on a result of the determination, wherein the traffic is scheduled on one or more resources that were not identified by the first access terminal if the first access terminal has not won the contention for the one or more of the identified one or more resources.
