In this paper, novel spectrum utilization efficiency (SUE) metrics are proposed for coexistence and spectrum sharing applications. A new SUE definition is formulated for each individual system, which, unlike the traditional SUE metrics, takes into account the impact of spectrum resource utilization efficiency in time, bandwidth and space. Then, new SUE metrics are proposed for spectrum sharing application, which combine the metrics of the systems that share the spectrum. The new SUE metrics not only consider the overall spectrum utilization by the systems, but also include their coexistence conditions in sharing the spectrum. Finally, computer simulation studies are carried out using the WLAN (Wireless Local Area Network) and LTE-U (Long Term Evolution in Unlicensed band) coexistence scenario to demonstrate the effectiveness of the proposed metrics.
