Scheduling QOS flows in broadband wireless communication systems

摘要

Systems and methodologies are described that facilitate enhanced resource scheduling for a wireless communication system. As described herein, packets associated with a common flow that arrive within a predetermined time period following a leading packet associated with the flow can be grouped into respective packet bursts. Subsequently, system bandwidth, transmit power, and/or other communication resources can be scheduled based on an analysis of the respective packet bursts. As provided herein, by analyzing respective packet bursts in lieu of individual packets, computational and resource overhead required for resource scheduling can be significantly reduced. In one example described herein, a resource schedule is determined by selecting one or more flows to be assigned bandwidth from among a plurality of flows based on an analysis of packet bursts respectively associated with the flows. Sufficient bandwidth can subsequently be scheduled for the selected flows for transmission of the respectively associated packet bursts.

1. A method for scheduling resources in a wireless communication system, comprising:
adjusting a burst length setting for executing a burst-based analysis upon received packets, the burst length setting comprising a predefined amount of time; identifying one or more flows that are yet to be assigned bandwidth; associating respective packet bursts with the one or more flows, the packet bursts respectively comprising a leading packet for an associated flow and one or more packets that arrive for the associated flow within the predefined amount of time with respect to the leading packet; analyzing the respective packet bursts by at least determining delay parameters and channel quality parameters associated with each of the respective packet bursts, the determined delay parameters comprising delay values representing an amount of time expired since the leading packet of the respective packet burst was received; and determining an order by which bandwidth is to be assigned to the one or more flows based on the analysis of the respective packet bursts wherein said adjusting the burst length setting is based at least in part on a target complexity level.
