吞吐量和节能网络切片

Throughput and Energy-Efficient Network Slicing

Bho Matthiesen, Osman Aydin, Eduard A. Jorswieck

摘要:

网络切片允许5G网络运营商向具有不同服务需求的多个租户提供服务。本文考虑网络切片感知的吞吐量和能源效率方面的最优资源分配。我们定义了一个异构的服务质量(QoS)框架的切片无线电接入网络网络与每片迫零波束成形,并联合优化功率和带宽分配跨切片和用户。该多目标优化问题的Pareto边界是由两种不同的算法得到的效用剖面和标量化方法结合广义分式规划。数值结果显示了联合分配带宽和传输功率的优点,以及吞吐量和全局能源效率如何受到切片特定QoS要求的影响。

英文摘要:

Network slicing allows 5G network operators to provide service to multiple tenants with diverging service requirements. This paper considers network slicing aware optimal resource allocation in terms of throughput and energy efficiency. We define a heterogeneous Quality of Service (QoS) framework for a sliced radio access network network with per-slice zero-forcing beamforming and jointly optimize power and bandwidth allocation across slices and users. The Pareto boundary of this multi-objective optimization problem is obtained by two different algorithms based on the utility profile and scalarization approaches combined with generalized fractional programming. Numerical results show the merits of jointly allocating bandwidth and transmission power and how throughput and global energy efficiency are influenced by slice specific QoS requirements.
