Title
Opportunistic Proportionate Fairness Adaptive Scheduler for High Speed Packet Access System
Abstract
3G MAC entity forms the most important part of any high speed packet access system. Due to high data rate requirements, MAC layer requires an efficient scheduler algorithm that can optimize the flow control, buffer utilization as well as channel quality requirements. The MAC entity consists of mainly the flow control engine, buffer management, scheduler and HARQ process that together provide a steady packet flow to the physical layer. In this paper, we propose a new algorithm to address the scheduler functionality. This algorithm provides the correct feedback to flow control and the HARQ process for data flow. The algorithm selects users for transmission bits based on their actual buffer occupancies per queue, dynamic token value traffic class priority, as well as channel conditions reporting from the access terminal. This algorithm is named as the opportunistic proportionate fairness scheduler (OPFS).
