Patent ID: 8199713

Claim:
A method for fractional frequency reuse in an Orthogonal Frequency Division Multiple Access Worldwide Interoperability for Microwave Access communication system utilizing a Partial Usage of Sub-Channels (PUSC) tile structure, the method comprising partitioning a sub-frame into a PUSC time zone with a frequency reuse of one and a PUSC time zone with a frequency reuse greater than one; scheduling resources for a mobile station in a sector in both PUSC time zones used by that sector by: establishing a scheduling queue for each resource partition ; and placing mobile station data traffic into each of the scheduling queues; providing scheduling metrics for each mobile station in each queue; and receiving a channel quality report from the mobile station for each resource partition; wherein scheduling includes scheduling transmissions for the mobile station in a sector in each zone used by that sector according to the scheduling metrics and the channel quality report; and wherein the scheduling metrics include a proportional fair metric for the mobile station in each resource partition; wherein the proportional fair metric (PPF) for the mobile station in any zone is given by: PPF =Spectral efficiency achievable in zone .alpha. /Average throughput for mobile station until current time .beta. where .alpha. and .beta. are fairness parameters.
