摘要

云无线接入网络(C-RAN)已被证明可以降低资本和运营支出,并提供高频谱效率(SE)和能源效率(EE)。远程无线电头(RRHs)的高密度部署导致能源消耗效率低下。此外,移动设备电池容量的提高远远落后于对传输功率的激增需求,这使得功率高效通信成为下一代无线通信系统的基本要求。本文考虑了一个由多个服务提供商共享超密集C-RAN (UD-CRAN)的网络。考虑了各服务提供商的QoS需求,提出了功率控制算法。通过模拟对性能进行了评估,并证明我们的算法在满足给定数据速率规范的同时提供了显着的能效提升。

Uplink Power Control for Ultra-Dense C-RAN with Non-Orthogonal Multiple Access
Cloud radio access network (C-RAN) has been shown to reduce both capital and operating expenditures and provide high spectral efficiency (SE) and energy efficiency (EE). High density of remote radio heads (RRHs) deployments results in inefficient energy consumption. Moreover improvements in the battery capacity of mobile devices lag far behind the surging demand for transmit power, which makes power efficient communication an essential requirement for the next generation wireless communication systems. In this paper we consider a network with multiple service providers share the ultra-dense C-RAN (UD-CRAN). We consider the QoS requirement of each service provider and propose power control algorithm. The performance is evaluated through simulations and demonstrated that our algorithm provides significant energy efficiency gains while meeting the given data rate specifications.
