Question: How is the generic Network Slice Energy Efficiency (EE) KPI affected when the 'Performance of network slice' (Pns) increases, assuming a constant 'Energy Consumption of network slice' (ECns)?
Option 1: The EE KPI remains unchanged since ECns is the dominant factor.
Option 2: The EE KPI decreases because higher Pns indicates inefficient energy use.
Option 3: The EE KPI increases, indicating the network slice is more energy efficient.
Option 4: The relationship between Pns and EE KPI is inversely proportional only for eMBB slices.
Explanation: According to the principles of network slice energy efficiency, for a constant unit of Energy Consumption (ECns), an increase in the Performance of the network slice (Pns) directly correlates with an increase in the generic Network Slice Energy Efficiency (EE) KPI. This means the higher the performance achieved per unit of energy consumed, the more energy-efficient the network slice is considered to be.
