Abstract

The 802.16e IEEE standard (WiMAX) enables efficient utilization of radio resources by leveraging the demand assigned multiple access (DAMA) technology. A number of uplink (UL) bandwidth request methods and traffic scheduling schemes are described in this standard; however, their particular implementation, including algorithms and methods of parallel execution are left for vendor´s discretion. A subscriber station vendor has to investigate various design options and their impact to the key quality of service (QoS) elements: traffic rate, latency, and jitter. The article provides recommendations and observations based on analysis of algorithms verified with a simulation tool.
