This document captures scope of the Multi-hop System Evaluation Methodology including the Channel Model, Traffic Model and Performance Metrics. This document is a Task Group document to which the harmonized contribution document C802.16j-06/042r2 has been converted as one of the baseline documents defined during the 2 nd Relay TG in session #44.

Incremental redundancy, or Hybrid type-II ARQ (HARQ), algorithms use a combination of forward error correction and retransmissions to guarantee reliable packet data communications. In this work, we propose a HARQ algorithm that exploits received packet reliability to improve system performance. Specifically, the receiver uses the average magnitude of the(More)
The identification and measurement of service quality are critical factors that are responsible for customer satisfaction. This article identifies 11 attributes that define quality of care and patient satisfaction and reveals various gaps among the patient, physician, and administrator groups in the perceived importance of those dimensions.

A multihop relay extension for IEEE 802.16e systems is the subject of ongoing standardization activities within the IEEE 802.16j Task Group. The emerging IEEE 802.16J standard enhances the 802.16e PHY and MAC to enable support of multihop routes between a mobile station and a base station through intermediate relay stations. Since it is believed that the(More)
The scientific field study of wildlife often requires vigilant observation of detailed animal behavior over extended periods. In remote and inhospitable locations, observation can be an arduous, expensive, and dangerous experience for field scientists. We are developing a new class of networked teleoperated robotic “observatories” that allows “citizen(More)
This contribution proposes that the scope of the MMR Task Group include 1) multiple relays rather than only a two-hop single relay path to the base station, 2) the option to study subscriber station relays in the path to the base station, and 3) the option to study relay for wireless backhaul. This contribution also proposes definitions for performance(More)
In response to presidential level directives to make additional spectrum available for commercial use, the United States National Telecommunication and Information Administration (NTIA) identified several government bands for consideration. One of the bands identified with potential for sharing with commercial users was the 4.2–4.4 GHz band. This(More)
