Abstract:

Due to the growing demand of green network, to investigate new energy-saving methods that can enable a transition towards a greener long term evolution advanced (LTE-A) is important. A technology based on coordinated multiple points transmission(CoMP) was adopted to improve the coverage where the initial serving cells are dormant. At first, the network is divided into several independent clusters according to equivalent cell principle. Then the designed model selects cooperative cells and corresponding dormant cells. Finally, two indexes were adopted to evaluate the efficiency of energy-saving method. Simulations show that the optimal clustering radius is 1600 m since the dormant cell rate and the quality of service are taken into account together, which prove that the technology is effective to manage energy consumption.

Key words: long term evolution advanced, coordinated multiple points transmission, equivalent cell, clustering radius, dormant cell rate
