METHOD, STATION AND MEDIUM STORING PROGRAM FOR PRIORITY BASED SCHEDULER WITH VARIABLE SCHEDULING PERIOD AND VARIABLE SCHEDULED PERIOD

摘要

PPROBLEM TO BE SOLVED: To provide a system and method for a time-scalable priority-based scheduler, wherein a flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. PSOLUTION: A rate request 408 is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment 418 responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for reverse link rate scheduling. PCOPYRIGHT: (C)2010,JPO&INPIT
