Low-complexity Dynamic Resource Slicing for Mixed Traffics in Virtualized Radio Access Network

摘要

In this paper, we investigate dynamic network slicing strategies with mixed traffics and multiple base stations in virtualized radio access network. Considering versatile user's QoS requirements on delay and rate, low complexity resource slicing algorithms and shape-based heuristic algorithm for user resource customization are devised in order to improve resource utilization and QoS satisfaction. To validate the advantage, a system-level simulation based on the 5G air interface design is conducted. Results show performances of the proposed algorithm outperform existing benchmarks.
