Self-Organized Energy Efficient Scheduling in LTE-A

Traditional packet scheduling is mainly designed for increasing spectral efficiency (SE) but not for the energy efficiency (EE). Self-organized network (SON) has prospective for self- configuring, self-optimizing self-healing and minimizes the energy consumption in the network. We consider self-optimizing and self-healing property of SON and investigate a novel energy efficient scheduling algorithm for LTEA. We first compare the state the of art scheduling in view of energy efficiency, then explain the tradeoff between EE and SE. System level simulation (SLS) analysis shows that the investigated SON approach achieves notable energy gain over traditional scheduling algorithm.
