Abstract: Resource allocation plays a significant role in current wireless communications. In order to improve the performance of the whole wireless network and social welfare, the limited network resources should be allocated efficiently and fairly. In this paper, a jointly guaranteed resource allocation scheme is proposed, which firstly introduces the required bandwidth and the desired bandwidth, and then combines the utility model with services that have different QoS (Quality of Service) requirements. An optimized model is built and the corresponding resource allocation scheme is proposed. The scheme could guarantee different QoS requirements, while the utility of the system could be improved. Furthermore, it can realize the fairness allocation between QoS and BE (Best Effort) traffics. The simulation results show that the proposed scheme can effectively improve the system utility compared with the traditional method, meanwhile, the goal of service oriented allocation is achieved, and the performance of the whole system is optimized.
