Adaptive Fair Resource Allocation and Packet Dependent Scheduling Using Cross-Layer Design in Multiuser OFDM Systems

In this paper, the authors consider a multiuser Orthogonal Frequency Division Multiplexing (OFDM) system and propose a fair resource allocation algorithm using cross-layer design with packet dependent scheduling. Their proposed algorithm achieves fairness among users (in proportion of weights of users) while maximizing the weighted sum capacity of users. Since, the optimal solution to the problem is computationally complex to obtain, a low-complexity suboptimal algorithm is proposed. It is assumed that each user is having multiple heterogeneous traffic queues.
