5. doc.: IEEE 802.11-14/1377r1 Agenda 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 or engage in the fixing of product prices, allocation of customers, or division of 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/about/sasb/patcom/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.

6. doc.: IEEE 802.11-14/1377r1 Agenda Introduction Purpose –Improve the working relationship between 3GPP and IEEE 802 Scope –The group will produce a slide or two on 802.11 coexistence lessons learned Outputs from this group must go through 802.18 Peter Ecclesine, Cisco Systems October 2014

7. doc.: IEEE 802.11-14/1377r1 Agenda LAA in 5 GHz Starting point is slides 14 and 17 https://mentor.ieee.org/802.19/dcn/14/19-14-0068-04- 0000-coexistence-lessons-learned-contribution.ppthttps://mentor.ieee.org/802.19/dcn/14/19-14-0068-04- 0000-coexistence-lessons-learned-contribution.ppt Besides the 3GPP liaison, what should IEEE 802 do? October 2014 Peter Ecclesine, Cisco Systems

8. doc.: IEEE 802.11-14/1377r1 Agenda IEEE 802 wants to work with 3GPP to achieve consensus on Wi-Fi/LAA sharing IEEE would like the opportunity to review the 3GPP coexistence simulation studies and provide feedback IEEE 802 would also like to review a range of documents throughout the period of the study item Examples of information 802 is interested in reviewing include, –The SI schedule as it develops –Details of the fairness criteria –The simulation scenarios –The LBT related parameters –The simulation methodology Our goal is for IEEE 802 and 3GPP to build towards a consensus on the best way for LAA to fairly share the same spectrum with 802.11 systems October 2014 Steve Shellhammer, QualcommSlide 8

9. doc.: IEEE 802.11-14/1377r1 Agenda IEEE 802.11 Coexistence Lessons Learned CSMA/CA works in ISM bands (such as 2.4 and 5.8 GHz band) where there is uncontrolled energy in the band IEEE 802.11 attempted to use TDMA-type systems (PCF and HCCA), and they have failed in the marketplace for a variety of reasons –It is impractical to coordinate access between low-cost independent systems, particularly for mobile devices moving across networks –The performance provided by CSMA/CA has proven to be good enough for the vast majority of use cases Licensed-exempt wireless systems cannot rely on the guaranteed reception of radio management and control traffic October 2014 Steve Shellhammer, QualcommSlide 9

10. doc.: IEEE 802.11-14/1377r1 Agenda IEEE 802.16h Coexistence Lessons Learned Note: of all the 802 systems, 802.16h is the closest analog to LTE in unlicensed bands The time-synchronization requirements of 802.16h systems are incompatible with deployed 802.11 systems Coordination access requires a high-cost high-speed control channel between 802.16h and 802.11 systems, which is impractical Coordination of policy between 802.16h and multiple 802.11 systems does not work since each 802.11 system is independent October 2014 Steve Shellhammer, QualcommSlide 10

11. doc.: IEEE 802.11-14/1377r1 Agenda Any Other Business We will post these slides and forward to Steve Shellhammer for modifying 0068r4 slides 12, 14 and 17. October 2014 Peter Ecclesine, Cisco Systems
