Abstract A double parameters cross-layer adaptive resource allocation scheme for multiuser OFDM system with heterogeneous types of traffic is proposed in this paper. By dynamically adjusting values of the two parameters: "delay compensatory factor" and "throughput compensatory factor" respectively, existing scheduling algorithms can be utilized flexibly and efficiently in the OFDM system. Simulations show that the scheme can achieve diverse levels of tradeoff between system power efficiency and traffic QoS satisfaction flexibly and fairness among different types of traffic can be guaranteed.
