Proportional fair scheduling is a wireless scheduling algorithm that maximizes the sum of log average rates for all users, i.e., if $R_k(n)$ then $\max sum_k \log T_k(n)$ where $n$ is the transmit slot number and $T_k(n)$ is a average rate given by

$T_k(n+1) = \left( 1 - \frac{1}{\tau} \right) T_k(n) + \frac{1}{\tau} R_k(n).$

This goal can be achieved using the following scheduling criterion

$k^*(n) = \arg \max_k \alpha_k(n) R_k(n)$

where $\alpha_k(n) = T_k^{-1}(n-1)$ [1]
