Abstract

In this article, we propose a non-orthogonal resource scheduling (NORS) scheme with an enhanced preamble detection (PD) method for cellular random access (RA) systems. The enhanced PD method is designed based on a deep learning technique that can classify three PD statuses: idle, collision-free, and collision. Because of this collision resolution capability, the base station (BS) can exploit radio resources non-orthogonally in contention-based RA protocols. In addition, we mathematically analyze the performance of our proposed NORS scheme in terms of RA success probability and resource utilization efficiency and conduct a comparison with the baseline orthogonal resource scheduling (ORS) scheme. Through simulations, we verify the validity of our mathematical analysis. As a result, our results will be a useful guideline for resource scheduling and provide support for massive connectivity.

蜂窝随机接入网络的非正交资源调度与增强型前导码检测方法

在本文中，我们为蜂窝随机接入（RA）系统提出了一种具有增强型前导码检测（PD）方法的非正交资源调度（NORS）方案。增强型前导码检测方法是基于深度学习技术设计的，可对三种前导码状态进行分类：空闲、无碰撞和碰撞。由于这种碰撞解决能力，基站（BS）可以在基于竞争的 RA 协议中非正交地利用无线电资源。此外，我们还从 RA 成功概率和资源利用效率的角度对我们提出的 NORS 方案的性能进行了数学分析，并与基线正交资源调度（ORS）方案进行了比较。通过仿真，我们验证了数学分析的有效性。因此，我们的结果将为资源调度提供有用的指导，并为大规模连接提供支持。
