Distributed Radio Resource Allocation in Highway Microcellular Systems

In this paper Distributed Radio Resource Allocation (DRRA) is investigated for highway microcellular systems. An algorithm, which combines the assignments of base station, channel and transmitter power, is proposed. The resource allocations are based on filtered measurements which are compared to fixed system thresholds. The performance of the proposed Threshold and Timer Algorithm (TTA) is evaluated in a model which includes user mobility as well as time-varying propagation conditions. The simulation results for the TTA scheme show that almost all channels can be used simultaneously in every cell, while still providing the sufficient communication quality. It is also demonstrated that the TTA algorithm outperforms a reference system using a Fixed Channel Assignment (FCA) strategy with a factor of 3.
