(C802.20-05-04r2)
Discussion followed
Review of Evaluation Criteria Document
Review of Section 3.2
The following is the new text for Evaluation Criteria Document Version 13:
FER vs. SINR is generated by the product of link-level simulations. Systems with adaptive modulation and coding should produce a set of curves (one curve per modulation and coding class). A second family of curves is the link-level throughput vs.
SINR. The link-level throughput is derived by using the FER as given in:
Throughput
 n


1

FER

/ T where “T” is the frame duration in seconds, and “n” is the number of information bits/frame supported by a modulation coding class.
Text was accepted without objections
Break: 3:00 pm
Resume: 3:30 pm
Review of Section 4.3.8
The group discussed the section and subsequently the text in the section was modified.
The group has agreed without objections to be included the following text as part of the
Evaluation Criteria document version 13 which will be voted later in the plenary.
Option 1: The de-jitter buffer window for the video streaming service is 5 seconds.
Option 2: The de-jitter buffer window for the video streaming service is a maximum of 5 seconds.
[need to confirm if the de-jitter buffer window size of 5 seconds needs to be changed for the higher data rate]
Review of Section 9.1
Discussion followed and three options emerged for consideration:

8
Option 1: Delete the section
Option 2: The proposed Option#1 presented in C802.20-04-82r1.doc
Based on the above four scenarios of channel environment, each simulated mobile user in the cell sites can be assigned a channel model with parameter values that are representative of the corresponding channel environment as described in Table 3.1 .
Option 3: The proposed Option#2 presented in C802.20-04-82r1.doc
Review of Section 6
Discussion followed
Chair proposed to have an ad hoc group (Arak Sutivong, Anna Tee and David Huo) to work on a unified proposal on System Level Simulation Calibration.
Time: 5:20 pm
Meeting recessed for the day .

Thursday, January 20, 2005
Meeting began at 9:00 am.
Chair reviewed the agenda for the remainder of the session given in Appendix C
Anna Tee presented the Ad hoc group report on “System Level Simulation Calibration”.
Discussion followed. There was no agreement on the text proposed and there were still differences in the interpretation of the text.
The chair presented alternative directions so as provide a clear understanding of the choices at hand and we can move towards the closure of Channel Models document
Alternative 1: Use an ITU model for SISO and the SCM model for MIMO
Alternative 2: Use Correlation ITU Mode;
Alternative 3: Use SCM for all
Break: 10:00 am
Resume: 10:30 am
Discussion followed on the different alternatives presented before the break.
Consensus emerged to go with Alternative 1 with some modifications.
The chair requested Mark Klerer to draft the modification to Alternative 1 for later review. This was reviewed later and given to the editor for input into the document.
Chair presented a summary of the relevant differences between SCM and Correlation
Model so as to provide a perspective in making the final selection on channel model.
Given the time of 11:15am, the Chairs suggested the next Contribution C802.20-04/72r1 be taken after lunch. Chairs suggested Next Meetings Planning and Next Steps be covered now. All agreed with the suggestions.
Chair reminded all that the next meeting is the march Plenary in Atlanta. He covered the latest status on the May Interim. The May interim will be either in Cairns, Australia or
Huntington Beach, CA. The Chairs of 802.11 and 802.15 were working on obtaining a decision quickly.
Chair stated conference calls were scheduled before the Plenary and all were encouraged to attend. A conference call schedule will be sent tot the mailing list. The plan is to use the calls and inputs from this meeting to update document version before the Plenary.
The Chairs reviewed inputs from the Access Technology presentation and agreed to send the groups inputs to the Chairs or .11 and .15.
Recessed for lunch.

10
Time 1:00pm
Dan Gal presented contribution C802.20-04/72r2 that was a cleaned up version of 72r1.
Review, discussion and comments followed. Key issues discussed included compliance with the Requirements, modification process for the Requirements and voting steps/process.
Discussion on the Technology Selection contribution continued after the break. Dan invited others to write contributions and additional proposals on this topic. He agreed to update another version of his contribution for discussion in Atlanta.
All agreed to adjourn.
Time: 4:45pm
