摘要 针对多小区LTE移动通信系统,考虑用户的最小速率要求,以最大化系统能效为目标,提出了一种迭代式的资源分配算法,通过不断迭代子信道分配和功率控制两个子过程来优化系统能效。针对子信道分配问题,提出了一种基于三种基本模式的子信道调整算法;针对功率控制问题,建立了多小区非合作博弈模型,理论证明了纳什均衡点的存在性,并设计了算法收敛于该纳什均衡点。仿真结果表明,与多小区最大化系统吞吐量算法相比,提出的算法获得了明显的能效增益,同时也达到了较好的系统吞吐量,尤其在强干扰环境下该算法的优势更加明显。

英文摘要 This paper proposed an algorithm for resource allocation under QoS constraint with the objective of maximizing system energy-efficiency in multi-cell LTE system.It was decomposed into sub-channel adaption and power control, and solved iteratively.The sub-channel adaption algorithm was based on three basic models.It developed an non-cooperative game for energy-efficient power control, and proved the existence of equilibrium.It also proposed an algorithm to solve the equilibrium. Simulation results demonstrate that the performance of this algorithm is more energy-efficient and result in most throughput.The performance is better in stronger interference.
英文关键词 multi-cell; energy-efficiency; sub-channel adaption; power control; non-cooperative game
