摘要
5G蜂窝网络因具有部署灵活、线缆成本低、移动性较强、服务质量（quality of service，QoS）控制完善和可扩展性强等优势，在工厂场景中具有很广泛的应用前景。但同时，工厂中的确定性业务对蜂窝网络控制也提出了一定的要求。所以在 5G-Advanced 的相关讨论中，业界也提出研究支持超低时延的5G蜂窝网络。为了满足2 ms的时延要求，提出了N3接口确定性和跨层调度优化两种关键技术以减少在传输网和空口的传输或等待时延。这两种技术在现有的蜂窝网络与确定性网络的互通通信机制和网络协议的基础上进行了改进，在对现有的网络协议改动不大的前提下，能很好地满足确定性业务较高的时延要求。
Abstract
Because of the advantages of flexible deployment
low cable cost
strong support for mobility and comprehensive QoS control and high scalability
cellular networks had been widely used in factory scenarios.At the same time
the deterministic service in the factory also puts forward certain requirements for cellular network control.Therefore
in discussions related to 5G-Advanced
the industry also proposes to research a 5G cellular network that supports ultra-low latency.To meet the delay requirement of 2 ms
two key technologies
deterministic N3 interface and cross-layer scheduling optimization were proposed to reduce the transmission or waiting delay on the transport network and air interface.These two technologies were the enhancement based on the current communication mechanism and network protocol between cellular network and deterministic network.The high delay requirement of deterministic services can be met well without changing the existing network protocol too much.
