APPARATUS, METHODS AND COMPUTER PROGRAM PRODUCTS IMPLEMENTING FAST BEARER PRIORITIZATION IN A MAC-HS PACKET SCHEDULER BASED ON REQUIRED ACTIVITY DETECTION

摘要

Apparatus, methods and computer program products provide fast instantaneous overload control during scheduling operations involving users in a wireless communications network who are candidates to be scheduled in a next transmission time interval. Apparatus detect congestion conditions in a wireless communications network by determining an instantaneous operating region of a scheduler (e.g., a medium access control-high speed scheduler) based on required activity detection and prioritize users in a scheduling candidate set based on the cost of a user. In a variant, this may be implemented by combining part of the required activity detection algorithm with a per- bearer cost function. In one implementation, this will limit the number of users that suffer during momentary congestion in the wireless communications network.
