  1. Guidelines for the Evaluation of Radio Transmission Technologies (RTTs) for IMT-2000(Overview of Recommendation ITU-R M.1225) Jose Costa Chairman, Canadian Evaluation Group (CEG) Tel.: +1 613 763-7574 FAX: +1 613 765-1225 E-mail: costa@nortel.ca

  2. Scope of the Recommendation • Radio transmission technology (RTT) considerations • Technical evaluation criteria and attributes • Test environments • Evaluation procedure • Summary evaluation methodology • RTT description template • Detailed evaluation procedures

  3. RTT Considerations Radio transmission technologies (RTTs) Multiple Physical channel Frame Duplexing RF-channel Modulation access definition and multiplexing structure technology parameters technology technology Synchronization requirements Spectrum efficiency requirements Source coder Channel coding Interworking

  4. Criteria for evaluation • Spectrum efficiency* • Technology complexity – Effect on cost of installation and operation • Quality • Flexibility of radio technologies • Implication on network interfaces • Handportable performance optimization capability • Coverage/power efficiency* *Objective Criteria

  5. Test Environments • Indoor Office • Outdoor to indoor and pedestrian • Vehicular • Mixed-cell pedestrian/vehicular • Satellite

  6. Step 1 Annex 1 Evaluation procedure Submission of candidate set of Radio transmission technologies radio transmission technologies description template Annex 2 Step 2 Test environments and Comparison with requirements deployment models and objectives Recs. ITU-R M.687, ITU-R M.816, ITU-R M.819, ITU-R M.1079 and ITU-T Rec. G.174 Intellectual property rights Step 3 policy of ITU Preliminary verification of technologies Section 6 Evaluation criteria Annex 3 Step 4 Detailed evaluation procedures Evaluation of set of radio transmission technologies for one Section 9 or more test environments Evaluation methodology Annex 2 Test environments and deployment models Step 5 Modification Step 6 Rec. ITU-R M.1035 Synthesis and grouping Step 7 Evaluation report

  7. Summary Evaluation Methodology • An evaluation summary is required from each evaluation group, but Rec. M.1225 does not specify any methodology to determine evaluation summaries. • The evaluation summary methodology may be numerical (e.g., using weights and scores) or non-numerical (e.g., using performance classifications). • Each evaluation group can define each own methodology.

  8. RTT Description Template

  9. Detailed Evaluation Procedures

  10. Canadian Evaluation Group (CEG) Approach Considering that • most RTTs already will come with a self-evaluation (i.e., a “vertical” evaluation); • Rec. M.1225 states that the procedure evaluates the candidate SRTTs as a whole as it is difficult to evaluate transmission technologies independently of each other; • time and resources are limited (1 July - September 1998). Resolves that • the CEG will perform “horizontal” evaluations, that is for each evaluation criteria/attribute the various proposals will be compared and evaluated; • priority will be given to the most significant evaluation criteria/attributes and the results will be summarized.
