Abstract

This paper researches the utility-based resource allocation problem in a real-time and non-real-time traffics mixed OFDMA cellular relay network to exploit the potentiality of relay. In order to apply utility theory to obtain an efficient tradeoff between throughput and fairness as well as satisfy the delay requirements of real-time traffic, a joint routing and scheduling scheme is proposed to resolve the resource allocation problem. Additionally, a low-complexity iterative algorithm is introduced to realize the scheme. Numerical results indicate that besides meet the delay requirements of real-time traffic, the scheme can effectively achieve the tradeoff between throughput and fairness.

Keywords: fairness; utility function; delay; radio resource allocation; real-time traffic
