摘要
新业务发展对5G上行速率和时延提出更高要求,结合全球5G频率使用情况,分析了高/低频段、TDD/FDD双工在5G上行容量、覆盖和时延性能方面的特性,在上行CA和SUL的基础上,提出一种TDD/FDD协同、高低频互补和时频域聚合的5G上行增强解决方案,具有更优的上行性能,最后给出了标准化方向的建议。
The emerging application development raises higher requirements for 5G uplink rate and delay.Based on global spectrum usage of 5G,this paper analyzes the characteristics of high/low frequency band,TDD/FDD duplex for 5G uplink capacity,coverage and delay performance.Based on uplink CA and SUL,a 5G uplink enhancement solution is proposed via TDD/FDD coordination,high and low frequency complement and time-frequency domain aggregation.The proposed solution has better uplink performance and provides suggestions to standardized direction.
