Abstract	The paper deals with power and subcarrier allocation in a frequency hopping - orthogonal frequency division multiple access (FH-OFDMA) based system. The problem is solved for the downlink of a cellular wireless transmission and the performance of the solution applied in two different frequency reuse schemes are compared. The proposed allocation strategy aims at minimizing the total power emitted by the base station (BS) and only requires the knowledge of the users' mean signal to interference plus noise ratios and rate requirements. We prove that in a universal frequency reuse scheme, the algorithm converges if the users' mean rate requirement is below a threshold which can be determined by the network designer. Moreover, numerical results show that this scheme outperforms the partial frequency reuse one under some cell size limit
