ABSTRACT:
A method includes tracking average user throughput, packet delay and jitter for every user that is serviced in an OFDM cellular system; using feedback to determine a potential schedule set responsive to user requirements for data and voice traffic responsive to minimum rate guarantee for data flows, and maximum tolerable delay and jitter guarantees for voice flows; with multiple flows for each user, first determining contending flow for each user responsive to aggregate rate feedback; obtaining search space for the user requirements of rate, delay and jitter responsive to corresponding optimizing strategies; determining individual rate, delay and jitter related schedules providing maximum incremental or marginal utility; and calculating final schedule of users on channels providing maximum incremental or marginal utility among parameter specific schedules form the determining step.
