An Energy-Efficient Scheduling Strategy in LTE System

Green communication has been a hot research in wireless network in recent years. The key question is how to reduce energy consumption while maintaining the quality of service. According to the conception of trading bandwidth for energy, a resource scheduling strategy based on system load conditions for LTE downlink is proposed to reduce energy consumption by improving energy efficiency at the cost of spectral efficiency. The two proposed algorithms can greatly reduce transmit power while meeting the users´ data rate are requirements, and ensure the realization of the fairness among users.
