On the feasibility of frequency reuse and spatial occupation in wireless device-to-device networks
Markus Klügel, Wolfgang Kellerer · 2014
Advanced, dynamic spectrum management techniques are needed for frequency reuse in tiered and heterogeneous wireless networks. For reuse of transmission resources, feasibility in a power control sense is of prime interest. In this paper, it is shown that by transforming the signal to interference and noise ratio (SINR) to a power fraction, feasibility of resource reuse can be identified. The influence of maximum transmission powers and noise on feasibility are evaluated. It is motivated that a degree of spatial occupation can be defined with power fractions and that infeasibility occurs when the overall required occupation exceeds a finite value. Based on these findings, a system model is presented that can be used to identify communication pairs for feasible resource reuse.
