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(5G)was designed to fulfill the mobile market requirements for higher data rate,lower latency and higher connection density beyond 2020.3.5 GHz spectrum was a typical band for 5G deployment and could be a global band for 5G development.The performance of 3.5 GHz 5G would be very meaningful as a reference for global operators.Based on the first release of 5G specification frozen in June 2018 by 3^rd generation partner project(3GPP),field trials of 5G network in typical urban area were conducted to validate the peak data rate,cell throughput and latency of 5G network.The trial results show that 5G NR system can achieved 1 Gbit/s peak data rate and 4 ms latency of single direction.
