Abstract

This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximise the capacity of the system. The scheduler has means (235) for maintaining a list of packets for a cluster of cells. A packet is selected from this list and processed in means (237) for calculating an increase in receive power level at a target base station and at other base stations caused by transmitting a packet. The results are fed to means (239) for scheduling packets to a base station so that only packets which do not result in an accumulated receive power level exceeding a maximum receive power level at a base station are scheduled. The scheduler is in particular appropriate for third generation mobile communication systems.
