5G专网大上行带宽技术设计与实现

Design and Implementation of Large Uplink Bandwidth Technology for 5G Private Network

在面向钢铁、矿山、港口、制造等行业的数字化探索中,发现行业用户在视频监控、机器视觉等场景对基站的上行吞吐能力存在迫切需求。然而电信运营商现用的2.5 ms双周期子帧配置时隙结构为7:3,即上行只占整个时隙配比的30%,上行吞吐能力并不突出。针对这一问题,发挥5G专网基站灵活的资源调度优势,设计了2.5ms周期子帧配置下时隙结构2:3传输方案,相比电信运营商常用的时隙结构配置实测上行业务速率可提升一倍。经过测试验证,所提出的大上行带宽实现方案可以显著地提升上行吞吐能力,满足行业数字化对上行吞吐能力的需求。

In the digital exploration of steel, mining, port, manufacturing and other industries, it is found that industrial users have urgent needs for the uplink throughput capacity of base stations in scenarios, such as video surveillance and machine vision. However, the time slot structure of the 2.5 ms dual-period subframe configuration currently used by telecommunication operators is 7:3, that is, the uplink only accounts for 30% of the whole time slot allocation, and the uplink throughput capacity is not outstanding. To solve this problem, this paper makes full use of the flexible resource scheduling of base stations in 5G private network, and designs a 2:3 transmission scheme with time slot structure under the 2.5 ms cycle subframe configuration. Compared with the time slot structure configuration commonly used by telecommunication operators, the measured uplink service rate can be doubled. After testing and verification, the proposed implementation scheme of large uplink bandwidth can significantly improve the uplink throughput capacity and meet the needs of industry digitization for uplink throughput capacity.
