Abstract (en)

[origin: WO0163855A1] Methods, systems, and arrangements enable packet scheduling in accordance with quality of service (QoS) constraints for data flows. In a Universal Mobile Telecommunications System (UMTS) network environment (100), for example, a Medium Access Control (MAC) layer (320) schedules packet transmission of various data flows to meet stipulated criteria, including permitted transport format combinations (TFCs) from a TFC set (TFCS). In first embodiment(s) (600), the TFC is selected based on guaranteed rate transmission rates, weighted fair queuing (WFQ) transmission rates (610, 805), QoS class, transport block set size (TBSS) (615), and optionally queue fill levels. These first embodiment(s) also further refine the selection process using backlog memories corresponding to previously unmet guaranteed and/or fair transmission rates. In second embodiment(s) (800), memory requirements are reduced by selecting a TFC based on guaranteed rate transmission rates QoS class, TBSS, and queue fill levels, without accommodating backlogs.
