第五代（5G）移动的通信系统期望通过密集地部署小小区来支持具有不同数据速率要求的用户。附着于小小区的用户使用与现有宏小区用户相同的频带，这导致严重的同信道干扰并降低性能。为了克服这一挑战，我们提出了一个博弈理论框架，用于小小区的最佳上行链路功率分配，即，毫微微蜂窝部署在宏蜂窝之下。在本文中，毫微微小区用户进行非合作博弈选择最佳功率，以最大化系统的和速率。此外，一个迭代的服务质量（QoS）感知的博弈论为基础的功率控制（QoS-GTPC）计划，提出了优化毫微微蜂窝用户功率考虑到宏小区用户的QoS要求。仿真结果表明，与传统的功率控制方案相比，所提出的QoS-GTPC方案显著提高了总速率，减少了中断和干扰。
The fifth-generation (5G) mobile communication system is expecting to support users with diverse data rate requirements by densely deploying small cells. The users attached with small cells make use of the same frequency band as the existing macro cell users, that causes severe co-channel interference and degrades the performance. To overcome this challenge, we propose a game theoretical framework for the optimal uplink power allocation for small cells, i.e., femtocell deployed underlaid macrocell. In this paper, femtocell users play a non-cooperative game to choose the optimal power to maximize the sum-rate of the system. Furthermore, an iterative quality-of-service (QoS)-aware game theory based power control (QoS-GTPC) scheme is proposed to optimize the femtocell user power taking into account macrocell user QoS requirements. Simulation results verify that the proposed QoS-GTPC scheme significantly improves the sum-rate and reduces outage and interference, as compared with conventional power control scheme.
