Abstract
As the number of user devices growing rapidly for the current 4G communications, it is expected that the problem of energy consumption for future mobile broadband communications will be more and more seriously. Therefore, how to effectively save the energy and reduce the carbon emission are very important issues for the green communications. In this paper, an analytic and energy-efficient location determination method of the small cell access (SCA) is provided for the Heterogeneous Network. The proposed method can be applied to any kind of distribution of the users in the considered region. Combined with the Coordinated Multi-Point (CoMP) technique, the energy consumption can be further reduced. Computer simulation and outdoor field experiments are conducted to verify the performances. Results demonstrate the correctness of the derivatives and the proposed method outperforms than the compared literature methods. According to the simulation results, the proposed method with the CoMP technique can save about 70% energy for the conventional co-located antenna system architecture and 20% compared with the uniformly distributed arrangement SCA method.
