TGe Consensus Proposal Month 2000 doc.: IEEE 802.11-00/xxx September 2002 TGe Consensus Proposal Authors: Airgo, Cisco, Intersil, AT&T, JVC, Matsushita, Motorola, Phillips, Pioneer, Sharp, Sony, Spectralink, TI This presents the status of the Date: September 12, 2002 Srini Kandela, et. al John Doe, His Company

September 2002 Context After 2+ years, insufficient support from 802.11 body to finalize TGe standard Major reasons for lack of consensus Bifurcation of market requirements data networking voice and audio visual Deeply held beliefs about how QoS should be in implemented in WLAN Continuous introduction of new concepts with varying levels of maturity Constant expansion of 802.11 membership Further delays in 802.11e standard may result in de-facto QoS standard forming outside IEEE Srini Kandela, et. al

Consensus Proposal Objectives: Month 2000 doc.: IEEE 802.11-00/xxx September 2002 Consensus Proposal Objectives: Pragmatic QoS standard that addresses key market segments: - data networking - voice - audio visual Easily accepted by >75% of the IEEE 802.11 body Focus on letter ballot comments. Goal is to: Simplify, Clarify, Unify Ad-hoc group members: Fast Track, Sharp, Intersil, Motorola. Socialized ideas with other members/ Srini Kandela, et. al John Doe, His Company

Status Ad-hoc group has reached consensus on September 2002 Status Ad-hoc group has reached consensus on eDCF improvements HCF polling Addresses needs of rate-based and time-based polling proposals Power Save extensions Normative text drafted for these proposals WME proposal (derived from Doc 02/592r0) HCF polling-spec (derived from Doc 02/524temp, original fast-track document) Power Save spec (Doc 02/562r2) Closure has not been achieved on all issues Srini Kandela, et. al

Improved eDCF Distributed Admission Control September 2002 Improved eDCF Distributed Admission Control Automatic Power Save Delivery eDCF clarification and simplification Maximum of 4 queues at STA and AP Rules for setting 802.11 user priorities in MAC frames Mapping 802.1d priorities to 802.11 priorities for data frames User priorities for 802.11 management and control frames Sequence number generation rules Srini Kandela, et. al

HCF Polling Unified Tspec Added Schedule element September 2002 HCF Polling Unified Tspec Addresses needs of rate-based and time-based Clarified parameter definitions Application triggered or autonomous Tspec signaling Added Schedule element Allows power management by STAs Normative HCF scheduler behavior Improves interoperability & testability Informative description of packet classification Srini Kandela, et. al

Power Save Extensions Automatic power save delivery method September 2002 Power Save Extensions Automatic power save delivery method STA and AP negotiate a wake-up period STA wakes up at negotiated period to receive Beacon AP may deliver 1 or more MSDUs to a STA, without receiving a PS-Poll STA goes back to sleep when More Data bit is set to 0 or if it receives a Beacon with the TIM bit set to 0 STA dynamically transition between active and power-save modes PS-bit in MAC header used to signal transitions STA can continue to use legacy PS-Poll method Srini Kandela, et. al
