Abstract
A method of scheduling transmissions in a multi-carrier transmission system, includes, for each downlink transmission frame: partitioning the downlink transmission frame into a plurality of data regions each including an equal number of slots, each data region corresponding to a respective logical band; for a currently active connection: a) creating a first set of logical bands not fully occupied for transmission and having a minimum boosting level making the transmission receivable by a receiving terminal; b) extracting from the first set, a second set of logical bands available for allocating a maximum number of slots for downlink transmission to the active connection; and c) selecting the logical band for downlink transmission to the active connection from the second set as the logical band that, after allocating the slots to the considered connection, leaves a residual number of slots equal to or smaller than a predetermined minimum residual in the logical band, e.g., the smallest residual number of slots.
