September 802.11 Discussion Premise


• WG16 is primarily interested in and SRIT which would require WG11 to submit as an RIT

• 802.11 indicted it was not interested in this path

• Is there a useful “Next Best” approach


• Need to generate .21 related slide by end of week?

IMT-A/802.11/802.21 – Target Topic Sep 08

• Background– IMT-A SRIT including 802.11 solution requires use of 802.16 – 802.11 is not sufficiently interested in IMT-A to submit its technology as a

RIT.– Without RIT status 802.11 would need to consider a less direct “partnership”

relationship such as 802.21 as a media independent handover mechanism for non-802.16 technologies

• Allows 802.11 to be compliant with 802.16 solution

• Goals– Is the 802.21 mechanism currently usable for 802.11/802.16 handover in the

context of IMT.TECH?– If not, exactly what needs to be added to 802.11, 802.16 or 802.21 to ensure

adequate functionality?

Questions #1

• 16 has mobile base stations and clients

• 11 has mesh , 16 has relay stations that could be fixed or mobile

• Can 21 handle all of these terminal types?

• Can 21 help? Can 21 meet circular letter requirements?

• How can 11 determine that it would meet minimum requirements to be accepted as an RIT?

Submission

Question List #2

• 3GPP has ANDSF which parallels (or uses) 21.

• If 11 could use ANDSF it would be a valuable option.

• 21 might be used to increase the number of RIT interfaces especially if tied into the 3GPP RIT if connected through ANDSF

• Is 21 specification mature enough to be used– Security is not developed

– Insufficient liaisons/support from mobile SDOs e.g. 3GPP

– 21 has good relationship with FMCA which suggests good link into wireline services with wired and wireless endpoints

• Rather than 21, interface thru TGu might be more viable– Better metrics?: Lower latency, shorter schedule time, security

– Is there anything missing from TGU?

– Does TGu have adequate liaisons and SDO acceptance?

• Is there any RIT that actually wants to partner with 11 in an SRIT?

Environments

IMT-Advanced: Required Test EnvironmentsThe critical decisions were made regarding the four “test environments”:• Indoor• Microcellular• Base coverage urban• High speedA 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.

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.

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).

IMT.TECH - 4.7 HandoverTABLE 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.

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.

• 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?

would review of IMTA requirements influence goals?

• 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?

Discussion• Data aspects of IMTA services/environments

– 802.11 vs other RIT candidates especially 802.16m

• Has the lack of recognition of 802.11 in IMT-2000 adversely affected market of 802.11. Looking backwards , there has been none. What about the future?

• Would continuing engagement with IMTA help?

• How valuable is access to IMTA spectrum to 802.11?

• Best case is actually more bandwidth and a much bigger market opportunity.

• There may be better ways to obtain spectrum such as 11y mechanisms for use of spectrum with non-exclusive licensing.

• How quickly/best can we determine complementary fit with 16m? Explore possibility of joint 11/16 teleconference discussion. Obtain/review 16m evaluation of IMT.TECH fit. How to achieve handoff (for example use of .21 mechanisms)? Timing of decision/engineering input – deadline?
