Dynamic multi-stage Energy-Saving Management mechanism based on Base Station cooperation

A novel dynamic multi-stage ESM (Energy-Saving Management) mechanism based on BS (Base Station) cooperation is proposed. The mechanism firstly introduces a local OP (Opposite Pair) cooperation method taking account of geographic topology and then divides time period into four domains. In time domains, regional dynamic multi-stage algorithms and efficient performance evaluation model for the mechanism is analyzed as well. The mechanism is simulated under a practical LTE BS deployment. Results show that 25.1% of regional energy can be saved at most. Still better coverage, interference, and throughput performance can be obtained comparing to other algorithms.
