在新一代移动通信中,协作多点传输技术因其可以有效提高边缘用户性能而被广泛研究。对于协作多点传输来说,其核心思想是通过不同小区间协作来改变边缘用户的性能,从而提升系统性能。针对单用户多输入多输出的特点,本文是在经典调度算法的基础上改进了的自适应调度算法,此算法在每个时频资源块上灵活的选择较优的传输模式,从而增强系统性能。通过仿真表明了这种调度算法在保持较好公平性的同时,又可以很好的提升平均小区吞吐量和边缘用户频谱效率。
In next-generation mobile communication, cooperative multi-point transmission technology has been widely researched because it can effectively improve the performance of edge users. For coordinated multi-point transmission, the core idea is to improve the system performance by changing the performance of edge users through cooperation between different cells. According to the characteristics of single-user multi-input and multi-output, this paper is an improved adaptive scheduling algorithm based on the classical scheduling algorithm. This algorithm flexibly chooses the best transmission mode on each time-frequency resource block to enhance the system performance . Simulation results show that this scheduling algorithm can improve average cell throughput and spectrum efficiency of edge users while maintaining good fairness.
