Super 3G: 3GPP 3G Evolution Slacker, Thank you very much for the links (and I'm repeating a few here). You saved me some time searching up the latest pertinent 3GPP links. When the recent 'Super 3G' articles stating that DoCoMo and 25 others planned to develop an advanced 3G RAN format were published it was unclear to me whether this was a 3GPP initiative, an IEE initiative, or an ad hoc, and whether or not it would make use of current IMT-2000 3G spectrum or new spectrum that will result from WRC-2007 for '4G' (whatever '4G' turns out to be). Clearly it is a 3GPP initiative making use of IMT-2000 3G spectrum and possibly 450 MHz, and it is not an unexpected initiative. Variable spreading OFDM in one form or another will likely be adapted for the downlink and possibly the uplink in this technology which is in the requirements stage, and it will feature an all IP RAN employing VoIP with no provision for circuit switched voice or data, but will undoubtedly be backwards compatible with WCDMA, HSDPA and EUL. This is very reminiscent of GSM Evolution beyond GSM Phase 1 and GSM Phase 2 which resulted in the open-ended GSM Phase 2+ standards) whose development is ongoing in 3GPP. That evolution began with requirements setting shortly after GSM was commercially launched in 1992. It had its roots in a talking document introduced within ETSI in early 1993 by Nokia which was followed by workshops similar to the recent 3GPP evolution workshop held later in 1993 that defined initial objectives and marked the beginning of planning for enhanced CSD (HSCSD) and packet switched data at medium data rates in existing cellular spectrum at 800/900/1800/1900 MHz. The commercial result is GPRS (GSM R97/R99/R4) and EDGE (R98/R99/R4/). The 50 page "Report of the 3GPP TSG RAN Long Term Evolution Work Shop" held in Toronto on November 2-3 you cited tells a rather complete story about what 'Super 3G' is all about and as an almost mandatory read for those that follow wireless: 3gpp.org The presentations from multiple carriers and vendors attending the conference are here: 3gpp.org This downloadable zip is from Docomo's 'Super 3G' presentation: 3gpp.org This is the 'Summary of Requirements' (zip) that were identified during 3GPP RAN long term evolution workshop: 3gpp.org Just as GPRS was an interim step to 3GSM UMTS and 1xRTT was an interim step to 3G before it was hyped as the poor man's dumbed down 3G, 'Super 3G' will undoubtedly be an interim step to 3GPP's candidate proposals) to the ITU for 4G. The term is likely to stick. The target for 3.9G standards completion (being functionally frozen) could well slip to 2008 or beyond. The target of commercial trials for 'Super 3G' in 2009 to 2010. Such is the nature of open committee based standards. Best and Happy New Year, - Eric -

3GPP TSG RAN Long Term Evolution Work Shop Below is an alphabetical list by contributor, of the contributions presented at the November 3GPP TSG RAN Long Term Evolution Work Shop, followed by an alphabetical list of the 27 companies attending the workshop who participated or observed but did not submit contributions, and the 'Summary of Requirements' that emerged from the workshop. There were 26 contributors, and those are obviously the initial 26 companies that the press has stated are involved in planning 3GPP's 3G evolution beyond Release 7 (Super 3G) which itself is still in the requirements stage.

3GPP: WCDMA Spectrum Aspects and Multicarrier One bullet in one of Nokia's slides caught my attention: * The current WCDMA standards are covering a large range of frequency spectrum, and more bands will be added shortly such as the ones informed by CEPT PT1(2.6 GHz & 900 MHz). While I fully expected 3GPP to tackle specifications that would downband WCDMA to 900 MHz for eventual refarming of that spectrum in Europe (and China) I did not realize that CEPT was already 'informing' on this. Note that the slide (#4) in REV-WS013 has an excellent reference for the 6 band combinations (I-VI) already standardized or for which standards are in progress: 3gpp.org Another interesting point that pervades many of the workshop presentations is this one: * With up to 20 MHz bandwidth, DS-CDMA not necessary the most attractive way to go Multicarrier technology worth considering: --> Scalable frequency allocation from 20 MHz down to 1.25 MHz --> Multiantenna techniques more attractive --> Re-use factor of one 3gpp.org Ironically, from a commercial and even in a mature standards POV, 3GPP2's Multicarrier CDMA is multicarrier in name only (wither 3xRTT), but work item proposals were recently submitted to 3GPP2 for multicarrier support for EV-DV and EV-DO by ALLTEL, Sprint, LG Telecom, and Ericssonto aggregate multiple 1xEV-DV/DO carriers to provide higher rates for packet data services ... Message 20846803 ... and I'm sure you recall Padovani's comments here: Future Direction: We demonstrated CDMA 2X multicarrier technology at CTIA Wireless 2003 as one of the migration paths for advancement of the peak data rate. But we have not yet taken any steps to commercialize it. ... We have taken a major step forward with [1xEV-DO] revision A in terms of efficiency. To go beyond revision A -- in terms of either improving the peak data rates or improving efficiency -- will involve a diminishing return, I believe, because we have already reached a point at which we're very efficient in terms of how many bits per second we can send. If it becomes necessary to further improve the peak data rate, then I think aggregating multiple carriers--either two or three--will really be the way to go with this technology. - Dr. Roberto Padovani, CTO of Qualcomm - neasia.nikkeibp.com I must say, that the body of 3GPP workshop presentations as a whole are a very interesting body of work. Best, - Eric -
