Network slicing is one of the key technologies of the fifth generation (5G) mobile communications for supporting various use cases with diverse quality of service (QoS) requirements. As each network slice is tailored to meet a specific set of QoS requirements, intelligent resource allocation becomes vital for network slicing. However, intelligent resource allocation that jointly consider throughput, power consumption, QoS and energy efficiency (EE) for network slicing has not been well studied. Therefore, in this talk, an intelligent, multiobjective resource allocation scheme that takes into account the aforementioned performance aspects for 5G network slicing under the architecture of heterogeneous cloud radio access network (H-CRAN) will be introduced. This resource allocation scheme encompasses allocation of baseband unit (BBU) pool resources among remote radio heads (RRHs), and resource block (RB) allocation among user equipment (UEs) by each RRH. In particular, the BBU resource allocation and the RB allocation are performed using a greedy algorithm and deep reinforcement learning algorithm respectively. Simulation results show that the proposed scheme can achieve a higher network throughput, better QoS provisioning and higher energy efficiency as compared with the baseline scheme.
