Abstract:
A Dynamic Spectrum Sharing (DSS) technique is presented, which allows dynamic access to the countrywide full 28 GHz Millimeter-Wave (mmWave) spectrum to an arbitrary number of Mobile Network Operators (MNOs) to serve their respective in-building Small Cells (SCs). Co-Channel Interference (CCI) is managed by controlling the transmission power of in-building SCs of each MNO. Using the Equal Likelihood Criterion and the properties of left-justified Pascal’s triangle, we derive the system-level average capacity, Spectral Efficiency (SE), and Energy Efficiency (EE) performance metrics. We carry out numerical analyses and simulation results for a country with four MNOs. It is shown that the proposed DSS can improve SE by about 2.64 times and EE by about 74.28% over that of the Static Equal Spectrum Allocation (SESA). Moreover, we show that the proposed DSS requires the reuse of the countrywide mmWave spectrum to 71.87% fewer buildings of SCs than that required by the SESA to satisfy the expected SE and EE requirements for the Sixth-Generation (6G) mobile systems.
