Chromatic scheduler for network traffic with disparate service requirements

Abstract

System(s) and method(s) are provided for managing network capacity in a wireless network that serves various traffic flows with disparate quality of service requirements. Management can be based on multi-stage scheduling in frequency-time domain. A first scheduling stage can generate an allocation of radio resources that minimizes inter-cell interference amongst a plurality of base stations. Based on the first-stage allocation of radio resources, a second scheduling stage can compute flow capacity for a set of radio resources specific to a base station, and acquire guaranteed-bit-rate (GBR) and non-guaranteed GBR traffic flows. GBR traffic flows can be matched to computed flow capacity to generate an allocation of frequency-time resources. In second scheduling stage, GBR traffic flows can be scheduled based at least in part on allocated resources and priority queuing. Based on allocation(s) in first and second scheduling stages, a third scheduling stage can schedule non-GBR traffic flows based at least in part on fair scheduling.
