  8. Supported Test Environments • At least 1 required to propose candidate • At least 3 required to enter final standardization phase. Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  9. Environments IMT-Advanced: Required Test Environments The critical decisions were made regarding the four “test environments”: • Indoor • Microcellular • Base coverage urban • High speed A radio interface technology (RIT) is required to satisfy the minimum performance requirements of a least one test environment, as specified by the proponent. A set of RITs (SRIT) needs to meet the requirements in at least two test environments. Later in the process, after evaluation of the proposals, only RITs or SRITs that meet the requirements in at least three test environments may proceed to be included in IMTAdvanced. It’s possible, for example, for a candidate RIT that meets only one test environment to proceed through the process and be evaluated. However, during the “consensus building” process, it would need to join with other RIT partners to form a SRIT covering at least three test environments in order to be included in the IMTAdvanced recommendation.

  12. IMT- Advanced IMT.TECH - Radio Requirements • 4.1 Cell Spectral Efficiency - Table 1 • 4.2 Peak Spectral Efficiency • 15 b/s/Hz downlink • 6.75 b/s/Hz uplink • 4.3 Bandwidth • At least 3, Scalable up to and including 40 MHz • 4.4 Cell Edge User Spectral Efficiency – Table 2 • 4.5.1 Control Plane Latency • <100ms • 4.5.2 User Plane Latency • <10 ms • 4.6 Mobility up to 350 km/h - Table 3, Table 4 • 4.7 Handover – Table 5 • 4.8 VOIP Capacity – Table 6 Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  13. IMT.TECH - 4.1 Cell Spectral Efficiency TABLE 1 Cell Spectral Efficiency Cell[1] spectral efficiency () is defined as the aggregate throughput of all users (the number of correctly received bits, i.e. the number of bits contained in the SDUs delivered to Layer 3, over a certain period of time) divided by the channel bandwidth divided by the number of cells. The cell spectral efficiency is measured in b/s/Hz/cell.[1] A cell is equivalent to a sector, e.g. a 3-sector site has 3 cells. Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  14. IMT.TECH - 4.4 Cell edge user spectral efficiency TABLE 2 Cell Edge User Spectral Efficiency The (normalized) user throughput is defined as the average user throughput (i.e., the number of correctly received bits by users, i.e. the number of bits contained in the SDU delivered to Layer 3, over a certain period of time, divided by the channel bandwidth and is measured in b/s/Hz. The cell edge user spectral efficiency is defined as 5% point of CDF of the normalized user throughput. Table 2 lists the cell edge user spectral efficiency requirements for various test environments. Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  15. Peak Spectral Efficiency • IMT.TECH - 4.2 Peak spectral efficiency • The peak spectral efficiency is the highest theoretical data rate (normalised by bandwidth), which is the received data bits assuming error-free conditions assignable to a single mobile station, when all available radio resources for the corresponding link direction are utilised (that is excluding radio resources that are used for physical layer synchronisation, reference signals or pilots, guard bands and guard times). Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  16. IMT.TECH - 4.6 Mobility TABLE 3 Traffic Channel Link Data Rates Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  17. IMT.TECH - 4.6 Mobility TABLE 4 Mobility Classes The following classes of mobility are defined: – Stationary: 0 km/h – Pedestrian: > 0 km/h to 10 km/h – Vehicular: 10 to 120 km/h – High speed vehicular: 120 to 350 km/h Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  18. IMT.TECH - 4.7 Handover TABLE 5 Handover Interruption Times The handover interruption time is defined as the time duration during which a user terminal cannot exchange user plane packets with any base station. The handover interruption time includes the time required to execute any radio access network procedure, radio resource control signalling protocol, or other message exchanges between the user equipment and the radio access network, as applicable to the candidate RIT or SRIT. For the purposes of determining handover interruption time, interactions with the core network (i.e, network entities beyond the radio access network) are assumed to occur in zero time. It is also assumed that all necessary attributes of the target channel (that is, downlink synchronisation is achieved and uplink access procedures, if applicable, are successfully completed) are known at initiation of the handover from the serving channel to the target channel. Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  19. IMT.TECH - 4.8 Voip Capacity TABLE 6 VoIP Capacity VoIP capacity was derived assuming a 12.2 kbps codec with a 50% activity factor such that the percentage of users in outage is less than 2% where a user is defined to have experienced a voice outage if less than 98% of the VoIP packets have been delivered successfully to the user within a one way radio access delay bound of 50 ms.

  30. Group Discussion/Suggestions • 2nd meeting Thursday 10:30am Capitol 7 Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  31. WG18 Meeting • Tuesday 10:30 am Quartz A • Joint WG discussion ITU-R WP5D • Outcome of Dubai meeting • Schedule & Milestones • Plans for correspondence group • Plans for Korea meeting (October 8-15) IEEE PLAN • Additional contributions to correspondence or meeting? • Plans for correspondence group • Plans for Korea meeting (October 8-15) Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  32. WG18 Notes • The meeting recommenced at 10:30 with the reports from the recent ITU-R meeting in Dubai. The first report port to IEEE 802.18 TAG on ITU-R 5D meeting #2. Was given by Roger Marks. • Roger went through the presentation and there were no questions. • Bruce Kraemer presented his report 802.11-08/0752r0, this document was posted into the Grouper Denver folder. The first part was on IMT-TECH. There were some questions raised but a commentator said that this document will be re-edited and revised at the upcoming October 5D meeting. • IMT-EVAL is continuing to be fleshed out and to date the presentation gives only the tip of the iceburg. There is a meeting soon that will do further work. There is a chart in the presentation giving the information on the future meeting dates. • The next steps will be for all interested 802 WGs to prepare edits and or new inputs for review and approval in a timely manner for the contribution deadline to next meeting, Korea October 8-15. • Some correspondence groups have been formed and should the IEEE take part in the process? • The individual groups should examine the steps and then decide their level of participation in the correspondence. Roger Marks indicated that 802.16 has a discussion group already in place as a correspondence group and that 802.11, and others, are welcome to join in. • Mike Lynch indicated that he would discuss this with 802.20 to see if they will join into the correspondence effort. • The Chair asked John Notor, the editor for the IMT output documents, to show the latest editing of the 802.18-08-0019-00- IMT802IMT Advanced Technology Proposal Process. • After presenting the document there was much discussion on how, in a timely manner, could the approval be obtained so that they could meet the contribution deadlines for the meetings. • Some brainstorming on how the documents can be made ready for approval by the EC recognizing that plenary meeting schedule makes an EC approval a very tight action. • The Chair thanked Roger and Bruce for their updates. John Notor will update document 18-08-0019r1 to 0019r2. Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  33. Next Steps • Continuation of activity in WG11, WG 18, WG16 Technical steps • Assessment of ability to meet baseline requirements • Submission to ITU-R • Operation in licensed bands • Cooperation with WG16 to construct SRIT submission Sanity checks • Sufficient interest in WG11 to support any of the above • Other, better alternatives • Connection to <6GHz PAR • Volunteers to participate/lead Bruce Kraemer (Marvell); Darwin Engwer (Nortel)

  34. What is the potential impact of IMT to 802.11?         Worst case scenario - future worldwide wireless system excludes 802.11         Best case scenario = IMT has zero impact to worldwide wireless system, i.e. IMT is a NOP Threat to 802.11 is likely zero,what is the opportunity • Should we stop this activity as it pertains to 802.11? • 802.16 might be a different story; seems to be more about operators staking out spectrum for the future. • Think of what we could do with more spectrum ... Extremely loose coupling between IMT and VHTL6         so 802.11 has no active effort working to meet the IMT requirements         we have essentially declared independence from IMT         was that intentional or accidental? • VOIP Capacity • Could we suggest a 64 kbps codec to yield VOIP capacity more in line with 802.11 capabilities? • What is the value of 100MHz channels for VOIP? • The IMT effort seems to heavily voice centric - should that be expanded to other areas for system comparisons? e.g. video streams. • Final thoughts:Can we write a submission that would lead to a reduction in the VOIP capacity metrics? • Get some feedback from 802.16m on how they view these requirements (esp. the VOIP capacity number). Where does 802.16m need help from 802.11, if at all, to construct a more complete submission? • How might 802.11 meet the VOIP requirements as they currently stand? • How might 802.11 compare/ emphasize video delivery? • Should 802.11 continue for inclusion in core specifications or for awareness?
