Overview: Most existing work on adaptive allocation of subcarriers and power in multiuser OFDM systems has focused on homogeneous traffic consisting of delay-constrained data or delay-tolerant data only. This research paper investigates the resource allocation problem in a heterogeneous multiuser OFDM system with both Delay-Constrained (DC) and No-Delay-Constrained (NDC) traffic. The objective is to maximize the sum-rate of all the users with NDC traffic while maintaining guaranteed rates for the DC traffic under a total transmission power constraint. An iterative algorithm is proposed to compute the optimal solutions numerically. A low-complexity suboptimal allocation algorithm is also presented.
