摘要
The explosive growth of mobile traffic has elevated the need to explore additional spectrum for fifth-generation (5G) networks in low bands (e.g., below 3GHz), mid bands (e.g., 36GHz), and high bands (mainly above 24GHz). To this end, it is imperative to study the interference of 5G systems into incumbent systems occupying these bands. In this paper, we study the coexistence of 5G Massive MIMO systems with incumbents in the mid-band spectrum between 3.7GHz to 4.2GHz, which are primarily fixed receive-only satellite earth stations (FESs) that are endowed with highly directive antennas. In particular, we analyze the aggregate interference experienced at FESs from the uplink and downlink transmissions of the 5G system. We then identify and present several interference mitigation techniques, including protection regions, power control, and frequency partitioning, to ensure harmonious coexistence. Finally, we present a case study of 5G deployment in a dense area, where we use an actual database of FESs for accurate analysis. Simulation results reveal that the favorable propagation environment sub-6GHz limits the opportunity of co-channel deployment, making frequency partitioning more desired for a practical coexistence.
