We analyze a dynamic channel assignment mechanism which selects the full-duplex channel that provides the minimum sum of signal strength measures on both uplink and downlink channels. In a previous work such a mechanism has been shown able to provide a remarkably better reuse degree than the “optimal” fixed channel assignment algorithm. In this paper we improve the analysis considering the impact of call admission control policies on system efficiency and flexibility. We show that a call admission algorithm based on the same signal strength measures used for the selection slightly impairs the reuse efficiency, but allow the system to exploit traffic fluctuations

Abstract

We analyze a dynamic channel assignment mechanism which selects the full-duplex channel that provides the minimum sum of signal strength measures on both uplink and downlink channels. In a previous work such a mechanism has been shown able to provide a remarkably better reuse degree than the “optimal” fixed channel assignment algorithm. In this paper we improve the analysis considering the impact of call admission control policies on system efficiency and flexibility. We show that a call admission algorithm based on the same signal strength measures used for the selection slightly impairs the reuse efficiency, but allow the system to exploit traffic fluctuations
