Emerging 5G URLLC wireless systems are characterized by minimal over-the-air latency and stringent decoding error requirements. The low latency requirements can cause conflicts with 5G EE design targets. Therefore, this work provides a perspective on various trade-offs between energy efficiency and user plane delay for upcoming URLLC systems. For network infrastructure EE, we propose solutions that optimize base station on-off switching and distributed access network architectures. For URLLC devices, we advocate solutions that optimize EE of discontinuous reception (DRX), mobility measurements, and the handover process, respectively, without compromising on delay.

5G 超可靠低延迟通信系统架构中的能源效率和延迟


新兴 5G URLLC 无线系统的特点是最小的空中延迟和严格的解码错误要求。低延迟要求可能会导致与 5G EE 设计目标发生冲突。因此，这项工作为即将到来的 URLLC 系统提供了能源效率和用户平面延迟之间的各种权衡的视角。对于网络基础设施EE，我们提出了优化基站开关和分布式接入网络架构的解决方案。对于 URLLC 设备，我们提倡分别优化不连续接收 (DRX)、移动性测量和切换过程的 EE 的解决方案，而不影响延迟。
