  1. IEEE C802.20-03/111

  2. Status of 802.20 Evaluation Criteria IEEE 802.20 Evaluation Criteria CG IEEE 802.20 Plenary Meeting November 10-13, 2003

  3. Evaluation Criteria Status • One conference call since the November Interim • Topics discussed over the conference call: • Sectorization, definition of spectral efficiency, mobility modeling, higher layers protocol models, control signaling models, fairness criteria and performance metrics etc. • Initial consensus reached on the Fairness criteria. • Version 06 of the Evaluation criteria document available (C802.20-03/94).

  4. Sectorization andSpectral efficiency • Recommendation to use 3-sector baseline configuration. • Spectral efficiency quoted as b/s/Hz/sector • The simulation data can also be provided for other configurations such as omni-cells

  5. Mobility model • Mobility at the physical layer is taken care of by modeling fast fading corresponding to the mobile speed. • A mobility model is still needed to assess the performance of various handoff schemes.

  6. Higher Layer Protocols • Models for higher layer protocols such as HTTP, RTSP and RTP etc. as applicable for various applications.

  7. Control signaling modeling • Examples of control signaling are scheduling grants transmission, channel quality feedback, and ARQ ACK/NACK Feedback etc. • MAC states and signaling to enable state transitions modeled explicitly in the system simulations.

  8. Performance Metrics • List of performance metrics used in the evaluation is incomplete. • Input needed from the traffic modeling CG on the list of applications supported before the application specific performance metrics can be defined.

  9. New Issues • Simulation and evaluation of various channel bandwidths?

  10. Summary • Little progress due to lack of contributions • Input from the traffic models CG • Application specific performance metrics and higher layer protocols details cannot be finalized until the details on the traffic models are available. • Input from the requirements CG : • Great level of detail and specification in the SRD would help simplify the evaluation criteria task.
