Abstract
This paper deals with multiuser resource allocation (power, bandwidth, constellation size, and code rate) for an OFDMA system using HARQ in the context of Rayleigh distributed channel. We assume that the resource manager (base station or cluster head) only knows the channel statistics of the active links. Then, an optimal algorithm for minimizing the total transmitted power under per user goodput constraints is proposed. Extension to imperfect feedback on HARQ scheme is also performed. This algorithm can be especially applied to military ad hoc wireless networks.
