Abstract
A method and apparatus for coordinating the resource assignment of a plurality of channel segments in a wireless communication system are disclosed. The method includes the steps of determining a number of resources available, determining a number of channel segments to include in a frame, determining a number of resource zones to be used for resource assignment of the plurality of channel segments, assigning each channel segment of the number of channel segments to a resource zone of the number of resource zones, and selecting a resource from the number of resources for transmitting said each channel segment in said resource zone.

A method for coordinating the hopping of a plurality of channel segments in a wireless communication system, comprising:
- determining, at a frame processing unit, a number of channel segments to include in each of a plurality of frames;
- dividing, at the frame processing unit, the frames into a plurality of resource zones to be used for hopping the plurality of channel segments, each resource zone containing a different plurality of contiguous frequency resource channels;
- assigning, at the frame processing unit, each channel segment to one of the resource zones, such that each channel segment is assigned to a different resource zone;
- selecting, at the frame processing unit, a first frequency resource channel within each assigned resource zone for transmitting the each channel segment in the assigned resource zone during a first frame of the plurality of frames;
- and
- selecting, at the frame processing unit, a second frequency resource channel within each assigned resource zone for transmitting the each channel segment in the assigned resource zone during a second frame following the first frame, wherein each first frequency resource channel is different than the corresponding second frequency resource channel.
