Malcolm -

Please note that there are 2 standards standards organizations' activities addressed in my reply.

cdma2000 activities are occurring within 3GPP2.

UMTS/wCDMA activities are occurring within 3GPP - and this is where HSDPA is being addressed. 3GPP is closely, inseparably aligned with the GSMA (the GSM Association).

"..Neither that nor the GPP's efforts say anything about the lifetime of the important patents for CDMA."

To my knowledge, I know of no organization that calls itself "GPP".

And to the contrary, the integration of HSDPA, also called UTRA - which is a high data rate technology intended to elevate UMTS/wCDMA data performance from the present 384kbs for Releases 99 and 4, to 2+mbs for Release 5 - has everything to say about the lifetime of the important patents for Qualcomm regarding UMTS/wCDMA (including the "td" flavor that presently has everyone's panties in a twist).

I'll give you another hint - Motorola was instrumental in introducing the fundamental technology components for HSDPA to the 3GPP. Coincidentally, Motorola developed another High Data Rate variant called 1xtreme. Are you familiar with 1xtreme's lineage? This would be another productive area of research for you to consider.

You can check for patents at this URL

164.195.100.11

use Qualcomm for term 1 and select Assignee Name in field 1. You can select various years. There are supposed to be 5 key patents covering power control, handoff and others( I have forgotten). First patents expire in 2007 or so.

1xtreme and HDR with voice added are attempts to use a broadaxe and slash off the QCOM family jewels (read IPR)by modifying the standard.

One of the key premises of 1xHDR is that voice and data have very different requirements and there will be inefficiencies anytime the two services are combined.
With that in mind, the 1xHDR design requires a separate CDMA carrier. It is however important to note that the 1xHDR waveform retains 100% compatibility with IS-95/1xMC from the RF standpoint. The 1xHDR waveform uses the same 1.228Mcps chip rate, link budgets, network plans, and RF designs on both Access Terminals and infrastructure. Furthermore, optimizing voice and data on different carriers is advantageous for both services: it simplifies system software development and avoids difficult load-balancing tasks.
Integrated 1xMC/1xHDR in a single network offers a complete solution that exceeds ITU 3G requirements substantially sooner than alternative technologies. 1xHDR's simplified and elegant "thin spec" evolved from cdmaOne field experience. 1xHDR working group was established in 3GPP2, TSG-C in March 2000. Numerous infrastructure manufacturers have publicly announced support for 1xHDR along with 1xMC.
1xMC/1xHDR systems proven technologies are the lowest risk alternative. 1xMC systems are currently being field trialed in various parts of the world. 1xHDR over-the-air system, available since September 1998, demonstrated features and data rates that are realistic from real field data experience. 1xHDR's forward link uses power efficiently. A single user is served at any instant; therefore avoiding power sharing and allocating the entire Access Point power to the user being served. The 1xHDR Access Point always transmit at full power achieving very high peak rates for users that are in good coverage area. Also, the data throughput is maximized via the efficient use of Access Point power. The Access Terminal and the Access Point jointly determine each user's forward link data. The Access Terminal measures the pilot strength, and continuously requests an appropriate data rate based on the channel conditions. The Access Point encodes the forward link at exactly the highest rate that the subscriber's wireless channel can support at any instant.
