HSDPA is much more similar to 1XTREME (remember that Moto/Nokia sponsored 3GPP2 technology?) than it is to QUALCOMM's HDR which became HRPD and was standardized as IS-856 1xEV-DO, but like HRPD it is a CDM/TDM hybrid. It is true that 1XTREME was Nokia's attempt to provide some convergence to the two standards (as well as wrest control of 3GPP2 away from Qualcomm), however many of the techniques to improve throughput that were underlying both 1XTREME and HSDPA were commercialized first in 1xEV-DO Rev 0. Every article that I have read about HSDPA points to the improvements over WCDMA coming from the support for Adaptive Modulation, HARQ, and fast scheduling. I dont know if the implementations are identical or even of Qualcomm owns the underlying patents but my understanding is that they all showed up first in 1xEV-DO Rev 0. Slacker
