Abstract
Based on the application of LTE technology in smart grid construction, this paper studies the technical background and demand of LTE technology and carrier aggregation technology in smart grid communication network construction, and analyzes the technical principle and technical background of LTE and carrier aggregation technology used in smart grid. Aiming at the problem of insufficient spectrum resources in smart grid construction, this paper focuses on the combination of carrier allocation and wireless resource allocation faced by carrier aggregation technology in smart grid environment. Carrier aggregation technology is used to improve spectrum utilization and speed up transmission speed. This paper studies a joint resource scheduling algorithm based on service priority, evaluates the service priority by studying the characteristics of wireless private network, and designs different scheduling methods for different services according to the characteristics of wireless resource allocation. The ns-3 simulation results show that the algorithm can provide sufficient resource allocation for high QoS services in the case of traffic congestion, balance the relationship between fairness and throughput, and improve the service transmission performance.
