5G载波聚合和双连接及提前测量上报技术研究

Research on 5G Carrier Aggregation,Double Connection and Early Measurement Report Technology

在第五代移动通信快速部署的今天,大量的新型业务涌现,这些新型业务对带宽的需求越来越大,载波聚合和双连接技术能够有效提升上下行带宽,大大提高了用户速率。另外载波聚合和双连接技术可以利用低频段上行覆盖的优势来弥补中高频段上行覆盖受限的问题。载波聚合和双连接在技术上有各自的特点和优势,载波聚合和双连接增强技术利用提前测量上报技术可以大大降低载波聚合和双连接在辅小区添加过程中的时延。

Nowadays,the 5th generation mobile communication is developing rapidly,lots of new businesses spring up,and these new businesses have strong requirements for big bandwidth.Carrier aggregation(CA)and dual connection(DC)technology can effectively improve the uplink and downlink bandwidth and greatly improve the transmission rate.In addition,CA and DC technology can use the advantages of low frequency uplink coverage to improve the uplink coverage in middle and high frequency.CA and DC have their own advantages,CA and DC enhancement technology can greatly reduce the delay of secondary cell addition by using the early measurement report technology,and it can improve the user experience significantly.
