This paper investigates the uplink dimensioning problem for OMA (Orthogonal Multiple Access) and NOMA (Non-Orthogonal Multiple Access) schemes. Dimensioning is to make radio resource provision for a service area to fulfill an outage constraint. The radio resource limit and outage in dimensioning make classical inhomogeneous Poisson assumption of uplink served user point process questionable. In this paper, we first prove that this process admits a homogeneous Poisson distribution in the limiting regime. As a consequence, uplink coverage probabilities over log-normal shadowing for both schemes are derived. Then, tractable stochastic geometry models for two schemes are proposed to obtain numbers of total required radio blocks. Their upper bounds under an outage constraint are also given to reduce computing overhead. Finally, the simulations confirm accuracy of derivations and demonstrate the effectiveness of our models.

针对 OMA 和 NOMA 方案的对数正态阴影的上行链路尺寸标注

本文研究了 OMA（正交多址）和 NOMA（非正交多址）方案的上行链路尺寸问题。规模化是为服务区提供无线电资源以满足中断约束。无线资源的限制和规模化中断使得上行服务用户点过程的经典非齐次泊松假设存在问题。在本文中，我们首先证明该过程在极限状态下允许齐次泊松分布。因此，推导出两种方案的对数正态阴影的上行链路覆盖概率。然后，提出了两种方案的易处理随机几何模型，以获得所需的无线电块总数。还给出了它们在中断约束下的上限以减少计算开销。最后，
