摘要
简要介绍5G系统的频段,概括分析大规模阵列天线的信道及增益模型,在介绍信道RB分配和MCS调制与频谱效率的基础上,具体阐述了5G上下行链路的覆盖能力。通过对业务信道和控制信道的链路预算分析,对其上下行覆盖瓶颈做出了详细的归纳和总结。另外,结合不同频段以及不同通道数的MIMO条件下5G的覆盖能力,对即将到来的5G的组网及优化给出了建议。
It briefly introduces the frequency band of 5G system and analyzes the massive MIMO channel and its gain model in general. On the basis of introducing channel RB allocation and MCS modulation and spectrum efficiency,it gives the 5G system coverage ability including uplink & downlink. By analyzing the link budget of traffic channel and control channel respectively,the bottlenecks of uplink and downlink coverage are summarized in detail. In addition,combined with the coverage of 5G under different frequency and MIMO conditions,the relevant guidance for the upcoming 5G networking and optimization is given.
