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 the new generation mobile communication, Coordinated Multi - Point Transmission/Re- ception technology is widely studied, because of its effectively improve the performance of the edge users . For Coordinated Multi - Point Transmission/Reception technology , its core idea is to change the performance of edge users through cooperating different cells, so as to improve the system per- formance. Based on the classical scheduling algorithm, according to the characteristics of the single user multiple input multiple output, an adaptive scheduling algorithm based on the proportional fair- ness algorithm was ,whlch in each resource block of time and frequency choose the better t ransmission mode flexibly, so as to enhance the system performance. The simulation results show that the novel scheduling algorithm can raise the average sector throughput and edge user spectral ef- ficiency, moreover,ensure the users maintain a good fairness.
