<I thought that only ONE user is served at any given time in an HDR forward link. The way I understood HDR was that it is a mix of CDMA/TDMA.>

According to GG:

Though HDR is code division between sectors, it is an adaptable dynamic TDM system for each connection. The reason for the TDM choice is the spreading code for a 2 megabit per second channel would be some 200 megahertz, which is not today technically feasible at reasonable cost.

So, TDMA on the forward link, maybe? Walsh encoding to overcome inter-sector/cell interference - there's a clever idea. And maybe, on the reverse slower link, CDMA?

So, what's up with Nokia?
