Abstract:
|
We propose a novel stochastic radio resource alloca-
tion strategy for the uplink that achieves long-term fairness in
terms of similar bitrates considering backhaul and air-interface
capacity limitations. We focus on a single cell scenario based
on WCDMA technology. We propose to use a maximin criteria
to introduce fairness among the different users’ throughputs.
An stochastic approximation is implemented to obtain an online
algorithm where the Lagrange multipliers are estimated at each
scheduling period. Our results show that the proposed scheme
achieves higher fairness among the users and, in some cases, a
higher sum-rate compared with the well-known proportional fair
scheduler. |
