5G新空口eMBB业务外场试验最新进展
|
摘要
结合第3代移动通信合作伙伴计划(3GPP)标准的最新进展,围绕第5代移动通信系统(5G)面向商用的产品研发、设计和选择了5G新空口(NR)系统的基站样机,并在典型的城区外场环境开展了5G增强移动宽带(e MBB)业务的外场试验,针对5G系统的峰值速率、小区吞吐量、覆盖能力、空口时延等性能进行了测试验证.测试结果充分证明,5G NR系统可以满足标准最初设立的性能需求指标.
As the Release 15 of the fifth generation of mobile system(5G) frozen in June 2018 by 3rd generation partner project(3GPP),the industrialization of 5G system is being accelerated for commercial launch towards 2020.As the next step of the production of 5G system,it is needed to validate if the 5G specifications can meet the minimum performance requirements defined by 3GPP.Based on the latest 5G specifications,a prototype of 5G new radio(NR) base station was designed and developed,and the field trial of enhanced mobile broad band(eMBB) was conducted in the typical urban scenarios.The key performance indicators were validated against the minimum requirements of peak throughput,cell throughput,coverage and latency.The results proved that the 5G prototype can fulfil the minimum requirements of 5G system defined by 3GPP.
