从移动的网络运营商的角度考虑吞吐量和延迟需求，同时依赖于随机几何和李亚普诺夫优化的无线电接入网络切片辅助移动的系统的效用优化问题。然后提出了一种联合虚拟资源优化算法，动态分配虚拟频谱和功率资源。我们的数值结果支持高吞吐量切片和低延迟切片，并量化相关的吞吐量与延迟的权衡。此外，我们将该算法与基准算法进行了比较，这确保了更好的实用性。
The utility optimization problem of radio access network-slicing aided mobile systems is formulated considering both throughput and delay demands from a mobile network operator's perspective, whilst relying on stochastic geometry and Lyapunov optimization. Then a joint virtual resource optimization algorithm is proposed to dynamically allocate both virtual spectral and the power resources. Our numerical results support both the high-throughput slice and the low-delay slice and quantify the associated throughput vs. delay trade-off. Moreover, we compare the proposed algorithm with the benchmark one, which ensures better utility.
