5. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 5 6.2 Policy IEEE standards may be drafted in terms that include the use of Essential Patent Claims. If the IEEE receives notice that a [Proposed] IEEE Standard may require the use of a potential Essential Patent Claim, the IEEE shall request licensing assurance, on the IEEE Standards Board approved Letter of Assurance form, from the patent holder or patent applicant. The IEEE shall request this assurance without coercion. The Submitter of the Letter of Assurance may, after Reasonable and Good Faith Inquiry, indicate it is not aware of any Patent Claims that the Submitter may own, control, or have the ability to license that might be or become Essential Patent Claims. If the patent holder or patent applicant provides an assurance, it should do so as soon as reasonably feasible in the standards development process. This assurance shall be provided prior to the Standards Boards approval of the standard. This assurance shall be provided prior to a reaffirmation if the IEEE receives notice of a potential Essential Patent Claim after the standards approval or a prior reaffirmation. An asserted potential Essential Patent Claim for which an assurance cannot be obtained (e.g., a Letter of Assurance is not provided or the Letter of Assurance indicates that assurance is not being provided) shall be referred to the Patent Committee. A Letter of Assurance shall be either: a) A general disclaimer to the effect that the Submitter without conditions will not enforce any present or future Essential Patent Claims against any person or entity making, using, selling, offering to sell, importing, distributing, or implementing a compliant implementation of the standard; or b) A statement that a license for a compliant implementation of the standard will be made available to an unrestricted number of applicants on a worldwide basis without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination. At its sole option, the Submitter may provide with its assurance any of the following: (i) a not-to-exceed license fee or rate commitment, (ii) a sample license agreement, or (iii) one or more material licensing terms.

6. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 6 Copies of an Accepted LOA may be provided to the working group, but shall not be discussed, at any standards working group meeting. The Submitter and all Affiliates (other than those Affiliates excluded in a Letter of Assurance) shall not assign or otherwise transfer any rights in any Essential Patent Claims that are the subject of such Letter of Assurance that they hold, control, or have the ability to license with the intent of circumventing or negating any of the representations and commitments made in such Letter of Assurance. The Submitter of a Letter of Assurance shall agree (a) to provide notice of a Letter of Assurance either through a Statement of Encumbrance or by binding any assignee or transferee to the terms of such Letter of Assurance; and (b) to require its assignee or transferee to (i) agree to similarly provide such notice and (ii) to bind its assignees or transferees to agree to provide such notice as described in (a) and (b). This assurance shall apply to the Submitter and its Affiliates except those Affiliates the Submitter specifically excludes on the relevant Letter of Assurance. If, after providing a Letter of Assurance to the IEEE, the Submitter becomes aware of additional Patent Claim(s) not already covered by an existing Letter of Assurance that are owned, controlled, or licensable by the Submitter that may be or become Essential Patent Claim(s) for the same IEEE Standard but are not the subject of an existing Letter of Assurance, then such Submitter shall submit a Letter of Assurance stating its position regarding enforcement or licensing of such Patent Claims. For the purposes of this commitment, the Submitter is deemed to be aware if any of the following individuals who are from, employed by, or otherwise represent the Submitter have personal knowledge of additional potential Essential Patent Claims, owned or controlled by the Submitter, related to a [Proposed] IEEE Standard and not already the subject of a previously submitted Letter of Assurance: (a) past or present participants in the development of the [Proposed] IEEE Standard, or (b) the individual executing the previously submitted Letter of Assurance.

7. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 7 The assurance is irrevocable once submitted and accepted and shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal. The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of those Patent Claims, or for determining whether any licensing terms or conditions are reasonable or non-discriminatory. Nothing in this policy shall be interpreted as giving rise to a duty to conduct a patent search. No license is implied by the submission of a Letter of Assurance. In order for IEEEs patent policy to function efficiently, individuals participating in the standards development process: (a) shall inform the IEEE (or cause the IEEE to be informed) of the holder of any potential Essential Patent Claims of which they are personally aware and that are not already the subject of an existing Letter of Assurance, owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents; and (b) should inform the IEEE (or cause the IEEE to be informed) of any other holders of such potential Essential Patent Claims that are not already the subject of an existing Letter of Assurance.

8. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 8 Other Guidelines for IEEE WG Meetings All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. Don t discuss the interpretation, validity, or essentiality of patents/patent claims. Don t discuss specific license rates, terms, or conditions. –Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings. Technical considerations remain primary focus Don t discuss fixing product prices, allocation of customers, or dividing sales markets. Don t discuss the status or substance of ongoing or threatened litigation. Don t be silent if inappropriate topics are discussed … do formally object. --------------------------------------------------------------- If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at patcom@ieee.org or visit http://standards.ieee.org/board/pat/index.html See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy for more details.

It should not be more than 4-elements. Minor changes (possible): Path loss model A1 looks fine. Heavy wall penetration should be maybe 10 dB instead of 12 dB, minor. Path loss model A2 for NLOS has very low standard deviation of 1.1 dB. Not sure why. Delay spread and angle of arrival models look ok.

The system should be flexible enough to support the various cell coverage scenarios that meet the performance target. To maintain the balance of the coverage, the cell coverage is considered to be the same between the downlink and the uplink. The performance requirements with respect to cell range are as followings: Up to 5km: The specified performance requirements above must be achieved. Up to 35km: Graceful degradation Symmetrical coverage between uplink and downlink And the performance requirements of the nomadic wireless access are as followings: Up to 100m: The specified performance requirements above must be achieved. Up to 500m: Graceful degradation.] The text highlighted in green should be changed to the following in yellow: Up to 30m indoors: The specified performance requirements above must be achieved.

48. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 48 Korea Text From 1268 (Korea): IMT-Advanced systems should support more than 100 Mbps in new mobile access environment and 1 Gbps in new nomadic/local area wireless access environment. For this, performance optimization can be done in either way. 1) One system can be designed to meet both of the new mobile access and the nomadic/local area wireless access requirements together. 2) Separate system can be designed for the new mobile access and the nomadic/local area wireless access requirements. The IMT-Advanced systems should be designed to provide best-in-class performance attributes such as peak and sustained data rates and corresponding spectral efficiencies, capacity, latency, overall network complexity and quality-of-service management. The IMT-Advanced systems should support applications that conform to open standards and protocols. The examples of applications are, but not limited to, video, full graphical web browsing, e-mail, file uploading and downloading without size limitations, streaming video and streaming audio, IP Multicast, Location based services, VPN connections, VoIP, instant messaging and on- line multiplayer gaming. The IMT-Advanced systems should provide the mobile user with an "always-on" experience while also taking into account and providing features needed to preserve battery life. The connectivity from the mobile terminal to the base station should be automatic and transparent to the user as it moves between mobile networks. 802.11 endorses the comments in this proposal with one exception. The text highlighted in green should be changed to the following in yellow: IMT-Advanced systems should support more than 100 Mbps in new mobile access environments and up to approximately 1 Gbit/s in new nomadic/local area wireless access environment. 802.11 Submitted text

It should not be more than 4-elements. Minor changes (possible): Path loss model A1 looks fine. Heavy wall penetration should be maybe 10 dB instead of 12 dB, minor. Path loss model A2 for NLOS has very low standard deviation of 1.1 dB. Not sure why. Delay spread and angle of arrival models look ok.

57. doc.: IEEE 802.11-07/2788r1 Submission November 2007 Bruce Kraemer (Marvell); Darwin Engwer(Nortel)Slide 57 Question about inter-system handover 802.11 has again begun to actively review the IMT.TECH and IMT.EVAL documents. In the course of our discussions we noted in your revised inputs on IMT.TECH (L80216-07_059) a deletion in 4.6.2 that puzzled us (see insert below). As you know, we are following the path of establishing a logical space for 802.11 equipment as conforming to the requirements for nomadic or indoor devices. In this regard we would foresee handovers between 802.11 and other air-interfaces such as 802.16m as being viewed as inter-system and hence the need for retaining the metric. Did you have a different explanation of the meaning of this term inter-system and a reason for the proposed deletion that 802.11 could both understand and support? I believe that 802.16 is proposing not to delete that topic but to move it. Our contribution (L802.16- 07/059) covers sections 1-4, plus the Table of Contents. The core is Cause 4, which addresses minimum requirements. I think you could argue that inter-system performance is not one of the core minimum technical requirements. After all, there are so many possible kinds of inter-system performance that it becomes impossible to specify a single performance number. I believe that this kind of thinking would suggest the strikeout that 802.16 suggested. Note, however, that the IMT.TECH Table of Contents includes 5.17.3 on "Inter-RAT Mobility[/Interworking]". Our proposal is to expand the topic by adding "and Handover". This might be a better place for detailed inter-system handover specs. While 802.16 did not submit input on Clause 5, I think that it may be interested in further developing that material. Perhaps we could consider some joint work with 802.11 on such development.
