论文摘要
在本文中，我们研究了大量多输入多输出（MIMO）系统的特殊下行链路方案的节能（EE）功率分配（PA）。我们考虑每个用户确保满足每个用户的服务质量（QoS）所需的最小功率。在此方法中，用户所需的最小功率之和与最大传输功率之间的比较是为了确定最大化EE是否可能。如果用户所需的最小功率的总和小于最大传输功率，我们将最大化EE。否则，群集中接收的用户的数量将最大化。在这两种情况下，仿真结果都表明，所提出的算法的性能比类似算法更好。
In this paper, we investigate energy-efficient (EE) power allocation (PA) for a special downlink scenario of the massive multiple-input multiple-output (MIMO) systems. We consider a minimum power required for each user to ensure that the quality of service (QoS) for each user is satisfied. In this method, a comparison between the sum of minimum power required by users and the maximum transmission power is done to determine whether maximizing EE is possible or not. If the sum of the minimum power required by users is less than the maximum transmission power, we maximize EE. Otherwise, the number of admitted users in a cluster is maximized. In both cases, the simulation results show that the proposed algorithm has better performance than similar algorithms.
