How does 5G ran work?
In 5G-RAN, the gNB systems within designated areas are combined into gNBs-clusters by aggregators. All gNBs-clusters are powered by the power system plane through power feeders, so switching the modes of a certain number of gNBs (sleep/active) and BESSs (charge/idle/discharge) can alter the power injection of the power system.
What is a 5G network?
The 5G network plane consists of three layers: 5G-CN, 5G-TN, and 5G-RAN.
