The IP packet convergence sub-layer is mandatory, while the ATM convergencesub-layer is optional. On the QoS level side, best effort and non-real-time polling areconsidered to be the main applications.5.3.6.2 PHY ProfilesThe baseband PHY basic profiles are given in Table 5-31, Table 5-32 and Table 5-33. Forall used modulation schemes the minimum receiver sensitivity levels are given. Note that64-QAM is mandatory only for unlicensed carrier frequencies.5.3.6.3 RF ProfilesOne of the important RF parameters is the spectrum mask, which is illustrated inFigure 5-43.
