3GPP2 Special Workshop on 3GPP2 Future Directions and IMT-Advanced Initial Workshop Report Ed Tiedemann (Qualcomm)Chair Clif Barber (KDDI)Secretary 16 May 2007 New Otani Hotel Osaka, Japan

16 May Workshop Action dated 19 March 2008 regarding Special Workshop on 3GPP2 Future Directions and IMT-Advanced from 3GPP2 SC Chair, Wan Yi : 3GPP2 Participants: At the recent 3GPP2 Steering Committee (SC) in Xiamen, we decided to hold a special SC level workshop. The workshop will address: –What is the future activity of 3GPP2 including enhancing current systems? –How will 3GPP2 address and work on IMT-Advanced? The Workshop will be held on Friday, May 16 in conjunction with the Osaka super-meeting. The Workshop will start at 10:00 on Friday morning and will last throughout the day. All TSG meetings are to have adjourned in time for the workshop. I view this workshop as an important step for 3GPP2. As a result of this workshop, I would like 3GPP2 to develop a tentative work plan that extends out for several years and which meets the interests of our subscribers, operators, and vendors. All 3GPP2 individual members and MRPs are encouraged to submit contributions and attend this Workshop. Ed Tiedemann has graciously agreed to chair this Workshop. The Workshop Chair will soon provide further details. I look forward to your inputs and vision at this important Workshop.

16 May People signed into workshop: 78 People counted: 81 Number of presentations: 19 –MRPs: 3 –TSGs: 4 –Members: 12 Number of presentations given: 18

16 May Main Areas Mentioned for 3GPP2 Work 1x –86% HRPD –93% Interworking with non-3GPP2 technologies –71% Femto cells –64% UMB –21% General Technology Enhancements (without mentioning a specific air interface) –29%

16 May Areas Mentioned for 3GPP2 Work Many other areas mention with interest, for example: SON, relays/mesh, common IMS A few companies provided some indication of schedule –1x and HRPD enhancements seem to be high priority Time frame for physical layer HRPD enhancements seems to be somewhat later than non-physical layer HRPD enhancements –Interworking also seem to be high priority

16 May IMT-Advanced Picture unclear on what to do for IMT-Advanced –Further discussion needed –Should solicit further input from community, particularly operators –Decision is up to 3GPP2

16 May Proposals on resolving IMT- Advanced Issue Survey membership Update SC vision document, but done under auspices of TSG-S –Does 3GPP2 want to do beyond 3G (IMT-Advanced); if so, what –Time line for 1x/DO enhancements –Type of enhancements for 1x and DO –Other areas for consideration (e.g., relays, interworking, femto) Update SC vision document, but done under auspices of TSG-S –Does 3GPP2 want to do beyond 3G (IMT-Advanced); if so, what Itemize possible IMT-Advanced approaches for 3GPP2; add +/- of each approach. This leads to a decision process

16 May How Do We Proceed Have meeting in Cancun to review the workshop report List # of companies indicating what to do (or not) on IMT-Advanced (as well as other areas) in the Workshop report Was modification of PPA a “can” or “should” do IMT- Advanced; address to Ops General consensus on moving forward on: –HRPD enhancements –1x enhancements –Interworking with non-3GPP2 technologies –Femto cells
