Efficient Resource Scheduling and Dispatch of Mobile Cell Sites to Improve 5G Performance

To fulfil the rapid growth of traffic demands and diverse network applications, 5G base stations (called gNBs) are being widely deployed. Due to some activities like sport events, the service area would be crowded with many user equipments (UEs). Thus, gNBs may not have enough spectrum resources to serve UEs, leading to low throughput and high packet loss. This paper uses a few mobile cell sites (MCSs) to solve the problem, which are gNBs equipped on vehicles and can flexibly move to serve UEs. We propose an efficient resource scheduling and MCS dispatch (ESMD) scheme, which helps each gNB allot resources to UEs to raise throughput. Then, we pick candidate locations for MCSs to move to help share loads of busy gNBs. Specifically, we adopt the Pareto-optimal concept to find one-to-one assignments between MCSs and these locations. Through simulations, we show that the ESMD scheme efficiently improves network performance in terms of throughput, packet loss, and the outage ratio.
