Patent ID: 8265019

Claim:
A method that facilitates scheduling a best effort flow and a flow with a delay requirement within a wireless communications environment, comprising: receiving a delay sensitive flow with a delay requirement; receiving a best effort flow; allocating a first portion of bandwidth to the delay sensitive flow; allocating a second portion of bandwidth to the best effort flow; reallocating the first portion of bandwidth to a reduced level of bandwidth and the second portion of bandwidth to an increased level of bandwidth if the delay requirement is met; reallocating the first portion of bandwidth to an increased level of bandwidth and the second portion of bandwidth to a reduced level of bandwidth if the delay requirement is not met; and maintaining a level of bandwidth for the first portion of bandwidth and the second portion of bandwidth if the delay requirement is equivalent to the first portion of bandwidth; and wherein the reallocation of bandwidth for the first portion of bandwidth is served by Wfi(gi(t), di(t), Kji (t)), where fi is a delay sensitive flow, W is a relative weight between priorities of best effort users and priority of delay sensitive flow users, j is a sub-band index, di(t) is a head-of-line delay for a flow, the qi(t) is a buffer size, and the Kji (t) is a spectral efficiency for a flow i at a time t.
