Abstract
Smart grid (SG) requires massive connections and ubiquitous interconnection, so it requires highly reliable communication services, and 5G communication is of great significance as an important means to ensure highly reliable transmission. This paper introduces the short block-length regime in 5G to meet the stringent requirements of smart grid highly reliable communication services. In addition, there are more and more types and quantities of grid terminals. Neighborhood Area Networks (NANs) need to transmit a large amount of delay-sensitive smart grid data at the same time, which also brings new challenges to network planning. This paper studies an uplink resource allocation scheme based on a heterogeneous cellular networks scenario. In order to maximize the system throughput, the objective problem is decomposed into two sub-problems, and an iterative algorithm based on first-order Taylor expansion linear approximation is proposed. Simulation results show that the algorithm can improve the data transmission throughput of grid devices, improve the efficiency of network resource use, and provide strong support for network planning.
