摘要
随着企业数字化转型需求的不断扩大,越来越多的企业用户提出了对5G专网的需求,而5G专网则存在传输性能的不确定性和设备高能耗等无线性能问题。简述了5G专网无线能力提升的业务需求,提出了使用2∶3时隙配比技术和室内分布式MIMO技术实现传输带宽能力提升,使用预调度、免调度技术实现传输时延能力提升,使用QoS、资源预留技术实现传输可靠性保障能力提升以及使用资源关断和休眠技术实现节能的技术方案。
With the continuous expansion of digital transformation demands of enterprises,more and more enterprise customers have raised their demand for 5G private network.However,5G private network has wireless performance problems such as uncertain transmission performance and high energy consumption.After a brief description of the business requirements for wireless capability of 5G private network,a technical scheme is proposed to use 2∶3 time slot allocation and indoor distributed MIMO technology to improve the transmission bandwidth capacity,use pre-scheduling and grant-free scheduling technology to improve the transmission delay capacity,use QoS and resource reservation technology to improve the transmission reliability guarantee capacity,and use resource shutdown and sleep technology to achieve energy saving.
