In this paper, the effect of the effective channel gain and the SNR using the improved Joint Resource Unit (RU) Allocation and Bit loading (JRAB) on a Filter Banks MultiCarrier (FBMC) system are analyzed. Computer simulations have been performed assuming a hypothetical WiMAX scenario in which an FBMC system substitutes OFDM by maintaining as much as possible the physical layer compatibility. From obtained simulation results it has been demonstrated that it is possible to upper-bound the maximum delay for delay-sensitive applications (rtPS and nrtPS) using the above mentioned effective metrics in a FBMC system.
