Abstract: An embodiment method for network optimization includes obtaining a first request to deliver a first data to a node in a network at a first data rate; obtaining a second request to deliver the first data to the node at a second data rate; and determining a flow decision schedule for a streaming session. The determining the flow decision schedule includes: scheduling a steady-state delivery period to deliver the first data at a steady-state data rate in accordance with the first data rate; and performing a best-effort allocation in accordance with the second data rate to determine a schedule for a supplemental delivery period, concurrent with at least a portion of the steady-state delivery period, to deliver the first data at a supplemental data rate.

Abstract: A method for effective flow rate estimation for a plurality of video flows includes determining a first flow rate of each of the plurality of video flows in a first transmission window and receiving quality of experience (QoE) feedback for playing portions of the plurality of video flows in the first transmission window. The QoE feedback is received from a plurality of user equipments (UEs) receiving the plurality of video flows. A dynamic effective flow rate is estimated for each flow in the plurality of video flows in a second transmission window in accordance with at least the first flow rates of the plurality of video flows and the QoE feedback.

Abstract: An embodiment method for performing joint scheduling in a cluster of base stations (BSs) of a wireless network includes receiving coarse scheduling information pertaining to external BSs and performing joint scheduling for the instant cluster of BSs such that a sum utility is maximized. The sum utility includes an out-of-cluster utility component representing interference observed by the external BSs as a result of the joint scheduling. The out-of-cluster utility component is computed in accordance with the coarse scheduling information.
