Claim Text:
1. A method for scheduling user equipment (UE) devices, the method comprising: receiving a request for a video service from one or more of the UE devices using a wireless network connection; establishing a hypertext transfer protocol (HTTP) connection with the UE devices; implementing a dynamic adaptive video streaming over HTTP (DASH) protocol to send a plurality of media content segments in response to the video service request; and scheduling the UE devices to receive the plurality of media content segments based on a weight of priority associated with each of the UE devices with respect to a plurality of subbands, wherein the scheduling comprises; wherein λ k,s (t) is a weight of priority of UE k on subband s at a t-th time transmission interval (TTI), r k,s (t) is a supportable data rate of UE k on subband s, W is a constant time window, U′ r ( r k ) is a gradient for a function U r at UE k in terms of average video rate, C′ q (q k (t)) is a gradient for a function C q at UE k in terms of playback buffer, D t is a duration of TTI, s f (t) is a size of a current video frame in transition, e k is a power consumption for receiving a unit throughput, and C′ b (b k (t)) is a gradient for a function C b at UE k in terms of battery energy.
