Claim:
1. A method for operating a base station of a wireless communications system, the method comprising: receiving a resource request for radio resources for a mobile station; assigning radio resources to the mobile station in accordance with the resource request, wherein assigning radio resources comprises assigning one or more mappings of a channel tree comprising at least a first set of mappings of radio resources and a second set of mappings of radio resources, wherein at least one mapping in the second set of mappings of radio resources is non-orthogonal to another mapping in the second set of mappings of radio resources such that multiple mappings within the second set of mappings allocate a common radio resource upon being assigned; setting values of individual bits in a bitmap based on the resource request, wherein bits in the bitmap indicate an assignment state for nodes in the channel tree, and wherein a bit in the bitmap corresponds to a single node of the channel tree; and transmitting the bitmap to the mobile station.
