Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2015 Abstract This presentation provides some thoughts for consideration, during the drafting of a submission from IEEE 802 to the 3GPP workshop on LAA, on August 29 Mark Hamilton, Ruckus Wireless John Doe, Some Company

Unlicensed LTE discussion is evolving Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2015 Unlicensed LTE discussion is evolving As evidenced as the ETSI BRAN meeting early this month, the discussions in this area continue to evolve quickly Other evidence from LTE-U Forum workshop and follow-on discussions, and work at WFA, etc. Recommend that 802/802.19/et al, take no action during the July plenary – rather start the drafting, work toward an August 10 approval, via EC e-mail ballot August 10 is still 4 weeks away, and a lot can change between now and then, and we want the submission to be as timely and relevant as possible.

Encourage including market req’ts Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2015 Encourage including market req’ts Do not fragment the market – that is the worst outcome for all of us Consider all the possibilities, work with all SDOs, ITAs, and vendors, to settle on one solution LTE-U – Effectively complete, but not deployed LAA – WI underway LWA – WI underway Standalone LTE – Being considered/desired in some markets Keep “Carrier-grade Wi-Fi” in mind, as that is coming soon. WBA is starting a program to consider market drivers Mark Hamilton, Ruckus Wireless John Doe, Some Company

Technical considerations Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2015 Technical considerations Reiterate statements from May liaison, encouraging ongoing work on simulations, and listen-before-talk mechanism study: IEEE 802 notes that there was an agreement (3GPP R1-152413) at the last 3GPP RAN1 meeting in April 2015 to undertake further simulation studies of an access mechanism that in many circumstances appears to operate in a similar manner to IEEE 802.11. In particular, it includes category 4 LBT, with similar timing and exponential back off (albeit with delayed feedback). IEEE 802 believes that this is an extremely positive development and looks forward to reviewing the simulations of this approach. Encourage 3GPP to consider all scenarios: Indoor/Outdoor/High Density/Hidden Node Video traffic, including real-time two-way video/voice/data Macro/small cell, and combinations Integrated LTE/Wi-FI, or standalone solutions Neutral host support WFA is doing coexistence simulations with open source tools, leverage that BRAN ‘agreements’ are a good start ??? Monitor, and adopt those Look forward to 5G. Don’t do something to make multi-RAN challenging/limited. Mark Hamilton, Ruckus Wireless John Doe, Some Company
