May 2007 doc. : IEEE 802. 15 -07/0727 r 1 Supporting Drop Eligibility in IEEE 802. 11 MAC IEEE P 802. 11 -07/693 r 0 • • This contribution proposes a mechanism for supporting frame drop eligibility in IEEE 802. 11 MAC. What Is Drop Eligibility? – The ability of a system (a network node, a station, an access point) to selectively drop frames when congested. Frame drop eligibility information is included in the frame header. • What does IEEE 802. 11 e Have? – – IEEE 802. 11 e user priority (UP) is based on IEEE 802. 1 D Defines 8 straight priority levls No consideration for discard eligibility. IEEE 802. 11 e somehow convolute the 8 priority levels with the 4 access categories (AC) – IEEE 802. 11 e operates on one-dimension only (urgency) – Only 4 code points levels are needed to support the a AC. • Suggests supporting IEEE 802. 1 Qad in 802. 11 which would provide for multiple options to support discard precedence.

May 2007 doc. : IEEE 802. 15 -07/0727 r 1 Dynamic Point-to-Point OFDM Adaptation for IEEE 802. 11 a/g Systems 11 -07/0720 r 0 This presentation evaluates a possible extension of 802. 11 a/g with dynamic OFDM. • In particular – Frequency-Selective OFDM Channel and Link Adaptation – Dynamic OFDM for P 2 P Links – Proposed Mandatory Transmission Sequence for Dynamic OFDM 802. 11 a/g Systems – Proposed Signaling Field extending the OFDM PPDU to support Dyn. OFDM Submission 5 Mike Mc. Innis, The Boeing Company

May 2007 doc. : IEEE 802. 15 -07/0727 r 1 Mechanisms in Support of Real-Time Mesh Deployment 11 -07/297 r 0 • This presentation discusses mechanisms that could be useful in support of real-time deployment of a multihop mesh network. • Link Measurement Request based on P 802. 11 k/D 7. 0 (January 2007) • Proposed the establishment of an Interest Group to gauge the level of interest in developing best practices for certain aspects of rapid network deployment, such as real-time link quality measurement, deployment algorithms, and power control mechanisms. Can lead to the development of a Study Group. • Approximately 9 people raised their hands showing further interest in this proposal. Submission 6 Mike Mc. Innis, The Boeing Company

May 2007 doc. : IEEE 802. 15 -07/0727 r 1 Mechanism for Link Quality Measurement 11 -07/650 r 0 • This presentation discusses the need for a standard mechanism to obtain link quality measurements, in particular to obtain timely bi-directional link measurements in mobile mesh networks. Recommends adoption of the Link Measurement Request/Report capability specified by TGk. Summary • Mobile mesh networks (e. g. , public safety and military usage models) require the ability to measure link quality on-demand – – • • For up-to-date link metric evaluation in time-varying channels To facilitate maintaining connectivity during rapid deployment of MPs Standard mechanism for link quality measurement ensures operation across vendors Link Measurement Request/Report capability specified by TGk satisfies these requirements – Submission Permits on-demand, bi-directional link measurement 7 Mike Mc.
