摘要

这项工作研究了持久性调度策略，以实现有限块长机制下超可靠低延迟通信（URLLC）的统计延迟要求。统计延迟模型是利用随机网络微积分（SNC）理论建立的。在持久调度框架下，得出了计算 URLLC 用户所需资源上下限的公式。此外，还推导出了在分配资源的情况下，可靠性和延迟性能要求之间的权衡公式。数值结果验证了所提公式的正确性。

A Method for Estimating the Resources Required by URLLC Users

This work studies the persistence scheduling strategy to achieve the statistical latency requirement of ultra-reliable and low latency communication (URLLC) in the finite blocklength regime. The statistical latency model is established by using the stochastic network calculus (SNC) theory. The formulas calculating the upper and lower bounds of the resources required by URLLC users in the persistent scheduling framework are derived. The formula describing the tradeoff between the reliability and latency performance requirements given the allocated resources is also derived. Numerical results verify the correctness of the proposed formulas.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
