摘要
FDD小区上下行频谱是对称的,上行感知通常不会成为首要问题,但TDD小区主流上下行子帧配比为1∶3,上行容易成为短板.文章对E频段进行重点分析,评估将全网上下行子帧配比修改为2∶2的可行性.通过可行性分析,我们发现,针对部分上行容量不足的高负荷场景,可局部进行子帧配比修改,通过调整子帧/时隙配比,更好地适应5G NR网络中上下行数据量不断变化的业务.在干扰抑制的前提下,其传输性能增益相对与半静态TDD配置更优.
Abstract
The uplink and downlink spectra of FDD cells are symmetrical,and uplink sensing is usually not the primary issue.However,the mainstream uplink and downlink subframe ratio in TDD cells is 1:3,which makes uplink easy to become a bottleneck.The article focuses on the a-nalysis of the E-band and evaluates the feasibility of modifying the downlink subframe ratio to 2:2 across the entire network.Through feasibility analysis,we found that for high load scenarios with insufficient upstream capacity,local subframe ratio modifications can be made to better a-dapt to the constantly changing upstream and downstream data volume in 5G NR networks by adjusting sub frame/slot ratio.Under the premise of interference suppression,its transmission performance gain is relatively better than the semi static TDD configuration.
