Packet scheduler and method therefor

摘要

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 maximize the capacity of the system. The scheduler has a selection unit (233) for selecting a candidate set of packets. The candidate set is fed to a processor (235) for calculating transmit powers required by remote terminals to transmit the packets based on the candidate set. The calculated transmit powers are fed to a controller (237) for modifying the candidate set in response to the calculated transmit powers and the modified set is fed to a scheduler unit (239) for scheduling the packets of the candidate set for transmission. The scheduler is in particular appropriate for third generation mobile communication systems.
