Query: Base Station Switch-off with Mutual Repulsion in 5G Massive MIMO
  Networks   When small cells are densely deployed in the fifth generation (5G) cellular
networks, switching off a part of base stations (BSs) is a practical approach
for saving energy consumption considering the variation of traffic load. The
small cell network with the massive multi-input multi-output (massive MIMO)
system is analyzed in this paper due to the dense deployment and low power
consumption. Based on the BS switch-off strategy with distance constraints, the
energy and coverage efficiency are investigated to illustrate the performance
of the BS switch-off strategy. Simulation results indicate that the energy
efficiency and coverage efficiency of the proposed strategy are better than the
random strategy. The energy efficiency increases with the BS intensity and the
minimal distance, and a maximum coverage efficiency can be achieved with the
increase of the BS intensity and the minimum distance. In this case, the
optimal BS switch-off strategy can be designed under this work in the actual
scene.
