DOWNLINK TRANSMISSION SCHEDULING IN MULTI-CARRIER NETWORKS

摘要

A method of scheduling transmissions in a multi-carrier transmission system, comprises, for each downlink transmission frame: partitioning the downlink transmission frame (200DL) into a plurality of data regions (30S1-SOSL) each comprising an equal number of slots, each data region corresponding to a respective logical band (3101-310L); for a currently active connection: a) creating a first set of logical bands not fully occupied for transmission and having a minimum boosting level needed to make the transmission receivable by a receiving terminal; b) extracting, from the first set, a second set of logical bands available for allocating the maximum number a slots for downlink transmission to said 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.
