Evaluation Criteria from March Plenary

Channel Models from March Plenary1. Review Version 8 for “Correct” restructuring and editing [Complete]2. Need Contributions for Completion3. Update of Open Issues will be created by Editor, send to the reflector

1. Create Version 15 based upon agreements reach in session [Version 15r3]2. Update the Open Issues list and set conference calls [Conference calls held]3. Start putting work on the email list again4. Need Contributions to close open items (example Link Budget section data rates

and associated table)5. New Open/Suggested work items – need contributions

A. New Section of QoS by Traffic type (see 05/20 & 05/22)B. VoIP alternatives

A. No Model – Technology proponent needs to show support for SRD Req.

B. Generic Model independent of vocoderC. Each Proponent supplies simulation based upon on their own vocoder

specific simulationC. System Calibration Resolution of a plan

A. calibration benchmark done by volunteer committeeB. “phase 0”C. Other choices

Technology Selection Next Steps from March Plenry

1. Create a 1.0 draft that Merges the Two Contributions and create options in sections where there is a difference- - Mark Klerer volunteers to try a merger and send out [This is complete see C802.20-05/24]

2. Appoint an Editor of the document - - Mark agrees to serve as acting[Below Not Complete] 1. Create additional Drop Box area for TSP2. Add Second Table regarding Evaluation Criteria from C802.20-05/19 to the

Evaluation Criteria doc as an Appendix3. All- Review for final approval the first table from C802.20-05/19 regarding

Compliance to SRD4. Compliant and Non-Compliant Proposals5. FDD and TDD Proposals6. Phases of EV and how it works in the process7. Consensus and adoption of an Agreed TSP8. Chair will obtain additional inputs on questions from .11n Chair and refer members to 802.21 TSP Doc.

Evaluation Criteria - - Version 15r3Major Open Issues

• Numerous Sections with options

• Traffic models (section 4.0)

• Handoff simulation model (section 5.4/5.5) – option 2 in 05/10r2 adopted in March meeting, need to modify as per members’ comments

• Phase II of Evaluation (section 6.2)• Channel Mix (section 9.2)• Simulation Calibration needs review of specifics (section 8)• Link Budget (section 11)

• Fairness criteria/QoS criteria for various applications to be evaluated as in Table 11 for phase 2 evaluation (section 15):

Phase 1 Simulation MethodologyNeeds review of last changes

• Full-Duplex, 19-cells, 3-sectors/cell wrap around configuration

• Traffic Type– Full-buffer (Hungry user; infinite backlog) model

• Channel model– Suburban Macro– Pedestrian B, 3 km/h, all users– Vehicular B, 120 km/h, all users

• Progress on open issues:

– System Calibration – further revision• Revised contribution adopted into EC V.14r1

– Link Budget – WG accepted modified text, with data rates for each test environment TBD• Revised contribution with 3 options included into EC V.14r1

– Performance metrics / output metrics • Consensus on Section 3.2 achieved during Interim meeting in January• Additional system-level performance metrics (C802.20-04/85r1)

– Receiver noise model• Need to achieve consensus on the proposed or refine text in Contribution 04/89r1

– Simulation flow• Proposed text in Contribution 04/85r1 need to be reviewed for adoption into EC

– Reverse link simulation model• Modeling of feedback / reverse link signaling errors discussed in Contribution 04/85r1• Need further discussion or appropriate text for EC

May 16, 2005 Chair, IEEE 802.20

Phase 2 Simulation Methodology – ConfigurationsStill Open

• Full Duplex, 19-cells, 3-sectors/cell wrap around configuration

• Traffic Types - as listed in Table 11 in the evaluation criteria document

– VoIP (RTP) • Model to be specified (proposed options for model: 05/23)
