Claim:
A method of wirelessly transmitting a multi-carrier communication signal between a base station and a plurality of users, the method comprising: determining a transmission link quality between a user and the base station; assigning a class type to the user based upon the transmission link quality; adjusting a number of sub-carriers comprising the multi-carrier communication signal and one or more of a number of timeslots, modulation rate, coding rate and transmit power allocated to select sub-carrier(s) of the one or more sub-carriers comprising the multi-carrier communication signal for transmission with the user based upon the class type; communicating the class type of the user to a MAC scheduler; and the MAC scheduler scheduling all transmission between the base station and the user by assigning transmission frequency slots and transmission time slots to the user, wherein a number of frequency slots assigned to the user per time slot is based on the class type of the user.
