The present disclosure generally discloses a scheduling control capability for controlling scheduling of transmissions where adaptive bitrate streaming is used for delivery of content (e.g., video content or other types of content which may be streamed using adaptive bitrate streaming) from source devices to end devices. The scheduling control capability may be configured to control scheduling of transmissions of adaptive bitrate streaming flows based on priority levels assigned to the adaptive bitrate streaming flows. The scheduling control capability may be configured to dynamically control the priority levels assigned to the adaptive bitrate streaming flows. The scheduling control capability may be configured to dynamically control the priority levels assigned to the adaptive bitrate streaming flows, for use in controlling the scheduling of transmissions of the adaptive bitrate streaming flows, in manner for improving user quality-of-experience, in a manner for improving spectral efficiency, or the like, as well as various combinations thereof.
