Priority-Based uRLLC Uplink Resource Scheduling for Smart Grid Neighborhood Area Network

Smart grid (SG) is playing an increasingly important role in today's power applications and the Neighborhood Area Network (NAN) is the access network connecting all the Home Area Networks (HANs) to collect data sending to the Data Concetrator Unit (DCU). Considering that the 5G uRLLC (ultra-Reliable and Low Latency Communication) technology can meet the stringent requirements of low latency and high reliability for critical services in SGNAN and that the number and variety of SG terminals increase rapidly, this paper studies the uplink uRLLC-based resource scheduling mechanism in the SGNAN scenario. The dynamic resource scheduling algorithm based on services priority is adopted in this paper to ensure low latency of high-priority services and urgent services, and to balance system throughput and system fairness. The simulation results show that the proposed algorithm can improve the throughput of more critical or urgent services while guaranteeing certain terminal fairness, which is more suitable for the SGNAN scenario than the exisiting algorithm.
