Abstract
The embodiments herein provide a method and apparatus for scheduling users of a communication system, based on an advantageous pre-scheduling scheme. As a first scheduler process during a current scheduling interval, first users selected for scheduling in the current scheduling interval are regularly scheduled to thereby make radio resource reservations for the first users. As a second scheduler process during the current scheduling interval, second users not among the first users are identified as having scheduling deadlines falling in a subsequent scheduling interval. As a further operation of the second scheduler process, the second users for the subsequent scheduling interval are prescheduled to thereby make radio resource reservations in the subsequent scheduling interval for the second users. The second scheduling may be performed using processing resources that would otherwise be left idle by the first scheduler process during the current scheduling interval.
