Data --coupla probably dumb questions -- does FDD HSDPA use/fill the unpaired [WTDD] spectrum, or is it "just" an equivalent to WTDD that can be deployed as an enhancement to FDD in the paired spectrum, that requires the paired spectrum? -- also, is FDD HSDPA as spectrally efficient as WTDD? -- finally, is/could there be such a thing as WTDD HSDPA, or does WTDD already effectively incorporate the data transmission efficiencies of HSDPA?

thanks
