Abstract:
In this paper, we present a Dynamic and Opportunistic Spectrum Access (DOSA) technique that allows access to the static and equal licensed 28 GHz millimeter-wave (mmWave) spectrum of each Fifth-Generation (5G) New Radio (NR) Mobile Network Operator (MNO) to every other MNOs in a country to serve their respective in-building Small Cells (SCs) subject to avoiding Co-Channel Interference (CCI). We derive the system-level Average Capacity (CA), Spectral Efficiency (SE), and Energy Efficiency (EE) performance metrics for an arbitrary number of NR MNOs. With extensive simulation results and analyses for four MNOs, we show that the proposed DOSA can provide CA and SE 2.5 times and improve EE by about 60% as compared to that of the traditional Static and Equal Spectrum Access (SESA) technique. Moreover, DOSA can achieve both SE and EE requirements expected for the Sixth-Generation (6G) mobile networks by reusing the countrywide mmWave spectrum for 46.87% fewer buildings of SCs than that required by SESA.
