1.Monday Morning Ad-Hoc Session, November 14, 2005
1.2.Opening
1.2.1.Call to order
1.2.1.1.Pat R. Calhoun (PatC): I call this ad-hoc meeting to order.
1.2.1.2.Meeting convened at 0800 hours.
1.2.1.3.PatC: I would like to briefly cover patent policy and the agenda of TGv, even though they will be covered again in the official session tomorrow (reviews patent policy and the agenda for the week). I would also like to use this meeting to provide time for several presentations.
1.3.Process
1.3.1.Presentation 05/629r2
1.3.1.1.Bin Wang, ZTE Corporation presenteddocument 05/629r2 – Load Balancing.Presentation advocates a mixture of AP and STA controls to effect load balancing . Said to be necessary to ensure that high QoS traffic can be effectively spread over an embedded cell network and to maximize network traffic handling and performance.
1.3.1.2.PatC: Are there any questions?
1.3.1.3.TimO: The figure on slide 5 shows a central highlighted cell with more clients than the surrounding cells. I believe that the number of clients is less important than the throughput in the cell in determining whether a cell is overloaded.
1.3.1.4.Unknown: It is instructive to note that “clients” may also be considered as VoIP clients, in which case one would want to balance the Erlangs across the network.
1.3.2.Presentation 05/630r0
1.3.2.1.Bin Wang, ZTE Corporation presenteddocument 05/630r0 – Adaptive Rate Control Requirements. Presentation advocates adaptive rate control. It observes that the current standard is simple, low overhead, and low in cost, but not capable of well-handling time-varying conditions, channel quality evaluation, while causing too much latency, and poor network utilization.
1.3.2.2.PatC: Questions?
1.3.2.3.TimO: I don’t understand what the presenter is asking for.
1.3.2.4.BobM: I think he is talking about using stronger rate control exchanges to achieve scheduling gain, particularly in situations where some clients at cell edges might unfairly use radio resources in the superframe due to reduced link margin.
1.3.2.5.PatC: Could you bring a slide on frame sequences, perhaps on Thursday?
1.3.2.6.BinW: Yes.
1.3.3.Presentation 05/1057r1
1.3.3.1.Bin Wang, ZTE Corporation presented document 05/1057r1 - Using AP's Location Information in Load Balancing. The presentation advocates using AP-centralized or cooperatively-orchestrated load-balancingto improve handover performance. 802.11k has provided a means for improving the process via transfer of location or neighbor information.
1.3.4.Presentation 05/1071r2
1.3.4.1.Bin Wang, ZTE Corporation, presented document 05/1071r2(r1 on server)-Solve Frequent Handover Requirement. Presentation targets use of load balancing to minimize handoff instablilities.
1.3.4.2.RogerD: These contributionsare complemented by some proposals being presented tomorrow addressing oscillations and ping-pong handovers. These methods have been thought out and should proving interesting to you.
1.3.4.3.PatC: Roger is suggesting that you wait until tomorrow to see if thesepresentations address your issues.
1.3.4.4.This concludes the items we wanted to cover this morning. We will recess until the official session at 0800 Tuesday.
1.4.Closing
1.4.1.Recess
1.4.1.1.PatC: Is there any objection to recessing this ad-hoc meeting?None.
1.4.1.2.Recess at 0955.
