摘　　要：5G负荷增长带来的控制资源受限问题日益突出,针对PDCCH信道,从容量的角度进行系统的研究,分析了不同用户模型下PDCCH的容量需求;在控制资源和业务资源的配置中保持平衡,兼顾资源利用率和用户感知;最终得出当PDCCH符号数配置为1/2/3时,一个小区可以满足50/200/200以上用户的日常调度需求的结论,并通过实验验证了方案的合理性。The problem of limited control resources due to 5G load growth is becoming more and more serious.It researches the capacity of the PDCCH,and analyzes the capacity requirements of the PDCCH under different user models.It balances the configuration of control resources and service resources,taking into account the resource utilization and user perception.It finally concludes that when the number of PDCCH symbols is configured as 1/2/3,a cell can meet the daily scheduling requirements of 50/200/200 plus users.And the rationality of the scheme is verified through practice.
