3.5GHz 5G新空口基站设计与外场实验研究
|
摘要
5G的设计目标是满足2020年以后移动通信市场的业务发展新需求,满足更高速率、更低时延、更大连接数密度等能力要求。3.5 GHz是目前全球规划的最典型的5G频率,并有望实现全球统一划分,5G在该频段上的性能表现对未来全球的5G部署具有极大的参考意义。结合5G新空口标准的第一个版本,中国移动联合国内合作伙伴开展了面向3.5GHz的5G样机设计和优化,并在典型的城区外场环境开展了小规模的外场实验,针对5G系统的峰值速率、小区吞吐量、覆盖能力等进行了测试验证。测试结果充分证明,5G新空口系统可以实现1 Gbit/s以上的峰值速率和4 ms的空口单向时延。
The 5 th generation mobile system(5 G) was designed to fulfill the mobile market requirements for higher datarate, lower latency and higher connection density beyond 2020. 3.5 GHz spectrum was a typical band for 5 G deploymentand could be a global band for 5 G development. The performance of 3.5 GHz 5 G would be very meaningful as a refer-ence for global operators. Based on the first release of 5 G specification frozen in June 2018 by 3 rd generation partnerproject(3 GPP), field trials of 5 G network in typical urban area were conducted to validate the peak data rate, cellthroughput and latency of 5 G network. The trial results show that 5 G NR system can achieved 1 Gbit/s peak data rate and4 ms latency of single direction.
