IEEE-SA Standards Board Bylaws on Patents in Standards
Approved by IEEE-SA Standards Board – May 2004
6. Patents
IEEE standards may include the known use of essential patents and patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either:
a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or
b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination
This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.

TGn Committee Report – Posted to Web
The following report is based on TGn closing report which is contained in the slides above.
TGn (High Throughput) achieved a significant milestone by completing the generation of its 4 selection criteria documents for Usage Models, Functional Requirements, Comparison Criteria and Channel Models. In compliance with TGn’s Selection Procedure, completion of these 4 documents allows the Task Group to release a Call for Proposals. The Call for Proposals will be issued on Monday May 17.
Specified within the CFP are three key dates
The posting of Letters of Intent (Friday, June 18)
Posting of Proposals and related documentation (Friday, August 13)
Presentation of Proposals (Monday, September 13)
9 Technical presentations covering various suggestions for High Throughput MAC an PHY improvements were heard as well.

17. IEEE P802.11 - TGn Backgrounder
July 2004 1.
IEEE P TGn Backgrounder
TGn will define the next generation standard for high speed wireless LANs.
The group's basic goal is to develop a standard capable of providing at least 100Mbps throughput at the MAC service access point. This is expected to provide roughly three times the throughput of current standards g and a.
TGn has defined comprehensive Functional Requirements, Comparison Criteria, Usage Scenarios, and Simulation Environments which must be addressed by the proposals in order to be considered for the final standard.
Complete proposals must address all of the requirements. Partial proposals, will most likely address various aspects of the MAC or Physical layer, but do not need to fulfill all the requirements indicated in the complete complement of reporting documents listed above.
A call for proposals was issued on May 17 and closed on June 18.
Following the close date of a formal call for proposals, the chair of Task Group n (TGn), Bruce Kraemer, has compiled and issued the list of individuals who have indicated that they will present a proposal.
The list of respondents includes 21indicating they will make complete proposals and 41 who wish to make partial proposals.
Proposals must be posted for membership review no later than August 13.
At the upcoming IEEE meeting in July TGn will plan for proposal presentations which will begin at the meeting in September.
Past experience with previous calls for proposals would indicate that due to consolidation and mergers the total number of presentations will be less than 61.

31. July 2004
TAG 19 –part r4
Overview
The introduction of a new or amended wireless standard creates the possibility of interference between the new standard and present standards. The purpose of these proposed changes to the LMSC policies and procedures is to establish a process in IEEE 802 to assure that the proposed standard and existing standards will coexist.
A Coexistence Assurance (CA) document is used as a tool for the WG and LMSC executive committee to assess coexistence with other users of the medium.
Coexistence is in the domain of MAC/PHY interactions between dissimilar systems. The criteria for a system resiliency to interference is ultimately dependent on the expected application of the proposed standard or amendment.
Kraemer, Conexant; Hillman, AMD

32. July 2004
TAG 19 –part r4
The role of TAG in this process is to act in the following ways:
Establish and maintain a set of methodologies giving guidance to the WGs on how to develop a CA document to characterize effects on users of the common medium, including the new standard or amendment.
Act as a resource to WG to help them decide which methodology is appropriate for their standard or amendment.
Assist the WGs in evaluating the results of their CA analysis when requested.
Evaluate the validity of the CA analysis WGs have completed in preparation for forwarding standards and amendments to sponsor ballot. This evaluation does not address if the proposed standard will adequately coexist. It does evaluate if the methodology was appropriate, executed, and reported correctly. LMSC makes the final determination on the level of coexistence necessary for the standard or amendment.
Kraemer, Conexant; Hillman, AMD

33. July 2004
TAG 19 –part r4
The process establishes what a wireless working group shall do at two steps in the standards development process:
At the PAR approval (or PAR corrigendum) phase a wireless working group (WG) shall indicate that it intends to submit a CA document or explain why it is not needed.
If the WG committed to create a CA document, the WG must submit it to the TAG prior to requesting that the SEC forward the draft to sponsor ballot. The TAG will offer its technical comments to the wireless WG and the LMSC.
When a wireless working group has a draft standard and has developed a coexistence assurance document, the wireless working group may submit the coexistence assurance document to the TAG for preliminary review.
Kraemer, Conexant; Hillman, AMD

34. July 2004
TAG 19 – part r4
Proposed addition to PAR process (procedure 2):
6.6 Coexistence
For a wireless project to be authorized, the WG is required to produce a Coexistence Assurance (CA) document to be submitted with their draft unless there is a compelling reason to omit this step.
Working Group will submit a CA document with the draft
Working Group will not submit a CA document
If no CA document, state reason: _________________________

TAG 19 – part 5
Proposed addition to LMSC standard procedures:
Procedure 11
PROCEDURE FOR APPROVAL TO FORWARD A DRAFT WIRELESS STANDARD
In the process of preparing for Sponsor Ballot, the WG shall provide the coexistence assurance (CA) document to the TAG no less than 60 days prior to requesting that the LMSC SEC send the draft to sponsor ballot. The LMSC recommends that the WG provide the CA document to prior to WG letter ballot.
The TAG shall give its technical comments on the CA document within 45 days after receipt.
The TAG will evaluate if the CA methodology was applied appropriately and reported correctly. The LMSC shall make the final determination on whether the coexistence necessary for the standard or amendment, as defined by the WG, has been met.

.21 Joint meeting
Thursday 8 am to 9 am in Hilton Grand Ballroom I.
 Questions from perspective, I would be interested in understanding the following:
1. Time frame for the development/publishing of the standard, which would help us determine by when certain inputs have to be ready in either direction.
2. An understanding of: Is it an amendment to the existing MAC/PHY defined by .11a/b/g or is it a completely new MAC/PHY. In case of former, what can/cannot be changed.
3. What input would TGn like from such that TGn is enabled for handover across heterogeneous networks.

38. .21 Overview PAR and 5 Criteria are on the IEEE website
July 2004
.21 Overview
PAR and 5 Criteria are on the IEEE website
IEEE is developing standards to enable handover and interoperability between heterogeneous network types including both 802 and non 802 networks.
PAR: The purpose is to improve the user experience of mobile devices by facilitating handover between 802 networks whether or not they are of different media types, including both wired and wireless, where handover is not otherwise defined and to make it possible for mobile devices to perform seamless handover where the network environment supports it. These mechanisms may also be useable for handovers between 802 networks and non 802 networks.
Kraemer, Conexant; Hillman, AMD

39. July 2004
.21 - More Par Detail
We define handover as the maintenance of sessions and/or service flows while connectivity is moved from one point of attachment to another.
The scope and purpose are derived from the need to address the following three problems that were identified during the study group phase:
– #1 Detection of a useable attachment to a network is impacted by the ambiguous indicators of network attachment in certain 802 MACs. Thus there is a need to develop a standard that allows a mobile terminal to optimize detection of a useable attachment to a network above the LLC.
– #2 The information necessary to make effective handover decisions is lacking in part because the 802 networks provide insufficient information to the upper layers. Thus there is a need to develop a standard that permits information exchange between mobile terminals and/or networks to enable mobile terminals and/or networks to make more effective handover decisions.
– #3 There is no standardized mechanism in 802 for information exchange between mobile terminals and network attachment points. This impacts the ability to make informed decisions to select between disparate network attachment points or to initiate handover between heterogeneous network types or between administrative domains within a single network type. Thus there is a need to develop a standard that permits mobile terminals and network attachment points to access information on which to base effective handover decisions.
