多小区MIMO系统中基于能效最大的天线数和用户数联合优化方案
摘要
In a downlink multi-cell multi-user MIMO system, the energy efficiency (EE) expression with respect to the number of BS antennas and number of users is first derived by considering a realistic power consumption model (PCM), including transmission power consumption and circuit power consumption. An energy efficiency optimization problem is then modeled by jointly optimizing the number of BS antennas and users to maximize system EE, and a two-step iterative searching algorithm is proposed to manage the problem based on the existence of an optimal solution. Finally, simulation results show that the proposed antenna configuration scheme based on optimal configuration of BS antennas and users can significantly improve system EE.
