摘要:
A scheduler and a method schedule available power and bandwidth to users. Equations for a continuous bandwidth allocation of a total bandwidth, and/or a continuous power distribution of a total power, are set up using Lagrangian multipliers to include constraints in a function that is maximum when a fair capacity is maximum. The continuous bandwidth allocation and/or the continuous power distribution represent sets of values corresponding to users that maximize the function. The equations are solved using waterfilling methods, wherein the continuous power distribution is determined for a previously determined bandwidth allocation, and/or the continuous bandwidth allocation is calculated for a previously determined power distribution.
