3GPP UMTS: The HSDPA extension of WCDMA & UTRA TDD Tom, << Dr J. was talking about HDR at the Feb 2000 annual meeting. I don't recall hearing anything about HSDPA for much later, probably until 2003. >> Qualcomm talked about HDR much earlier than Feb 2000. You'll probably find references dating back to 1997 from Andy Viterbi, Ed Tiederman, IMJ, and others. We have been discussing UMTS HSDPA on this particular moderated board since December 2000. This one from Slacker: Message 15036735 HSDPA concepts were contained in the 3GPP 'R99 standard (RAN #6 December 1999). Active discussion took place on HSDPA in 3GPP in March 2000 (RAN#7) and development of the concept was approved at that meeting as a feasibility item for Release 4 although it was subsequently pushed to Release 5. 3GPP published TR25.848, Physical layer aspects of UTRA High Speed Downlink Packet Access, version 4.0.0, one year later in March 2001. March 2000 is of course when HDR - subsequently standardized as IS-856 - was formally introduced to 3GPP by Qualcomm, and concurrently for CDMA2000 evolution which would integrate voice and high speed packet data in that same carrier, Motorola and Nokia proposed 1Extreme to 3GPP2, and other similar proposals were also introduced to 3GPP2 by Samsung, Lucent, and Qualcomm. In October 2001 I quoted Nokia's Harri Holma and Antti Toskala on the subject of HSDPA on the moderated Nokia board: Message 16539820 Although I haven't searched up the links, I subsequently posted here on this board on the 3GPP/3GPP2 HSDPA/1xEV-DV/1xEV-DO harmonization meeting that took place in New Jersey in mid November 2001: 3gpp.org There is a good relatively recent (January) article by Nokia's Antti Toskala on HSDPA here in EETimes: commsdesign.com << For a long time it wasn't clear if there would be an HDR proxy on the WCDMA track. >> I'm not exactly sure what an 'HDR proxy' is, but it was perfectly clear to anyone watching standards evolution in 3GPP that data transmission to the ITU mandated 2 Mbps would be pushed to R4 in 3GPP and that data transmission beyond that (to ~10 Mbps or better) would evolve in R5/R6, and that similar concepts were deployed in CDMA2000 Releases C&D and even the separate IS-856 Revision A standard. << So what are the precursers for HSDPA from other companies? Who contributed important IP besides Q and where did this IP originate? >> Although Qualcomm was a 3GPP participant since 3GPP's inception in December 1998 by virtue of its ETSI membership, they were a decidedly passive participant until 2001. You will find relatively few contributions from Qualcomm on HSDPA prior to the completion (functional freezing) of R5 in March 2002 or especially the definition o9f the physical layer a year prior. Fundamental IP for HSDPA is held by the 3GPP contributors to the standards evolution: Motorola; Nokia; Ericsson; Siemens; Alcatel; Texas Instruments; and many others. Some might be held by Qualcomm.
