Context
After 2+ years, insufficient support from 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 membership
Further delays in e standard may result in de-facto QoS standard forming outside IEEE

Consensus Proposal Objectives:
Pragmatic QoS standard that addresses key market segments: - data networking - voice - audio visual
Easily accepted by >75% of the IEEE 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/

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)

September 2002
Improved eDCF
Distributed Admission Control
Automatic Power Save Delivery
eDCF clarification and simplification
Maximum of 4 queues at STA and AP

Srini Kandela, et. al

7. 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

8. 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

Open Issues
MAC SAP definition to support both prioritized and parameterized QoS traffic
Data SAP: Size of user priority tag (3 or 4 bits)
Control SAP: Extensions to support Tspecs
Security for side-channel traffic
AIFS definition
HCF Polling: Mandatory or Optional at AP?
