Abstract
In the method, an average user throughout over all active users is computed, and each user's user perceived throughput is compared against the computed average throughout. Based on the comparison, the scheduling of the plurality of users is prioritized. In an embodiment, a priority adjustment factor is applied to each user to prioritize the scheduling of users to receive a data transmission. The priority adjustment factor is determined based in part on an update function. The update function is proportional to a calculated difference between each user's user perceived throughput and the average user throughput. Based on the sign of the update function, the priority adjustment factor is either incremented or decremented, and hence, prioritization of users is ordered. The output of the scheduler is user identifying information that informs the base station to transmit data in a current time slot to the identified user determined as the highest priority user by the scheduling method.
