Abstract
In this paper, we study the interferencemanagement and resource allocation problem in apacket-switched, fixed, broadband, Time DivisionMultiple Access (TDMA) wireless system. These systemshave the potential to provide high-speed data access to the homeand therefore are of current interest. The systemcapacity is limited by the co-channel interference,which arises from both intercell and intracelltransmissions. The intracell interference management andresource allocation, which significantly impacts thesystem performance, is the focus of this study. The goalis to design efficient resource allocation schemes to combat intracell interference so as toimprove the system capacity and service quality. Weaddress the following issues: (1) estimating the optimalcapacity of the system; (2) proposing resourceallocation schemes with reasonable complexity that areclose to optimal; and (3) proposing a new class of powercontrol schemes that are suited to intracellinterference management. Two resource allocation schemes are proposed: Max-Min Scheduling Protocol(MMSP) and Revisited Max-Min Scheduling Protocol(RMMSP). We show via simulations that these schemescombined with the new power control provide close tooptimal performance.
