I was also trying to determine if HSDPA technology could be applied to TDD also, to supercharge TDD in a similar way as it appears to be doing with FDD. Thus HSDPA-enhanced TDD should still carry its distinct data advantages over HSDPA-enhanced FDD.
Yes - HSDPA has implementations in both FDD and TDD modes. Most of our contributions have been made to the TDD side, and following on with the HSDPA contributions.
Here is where you can download the specs.....where the STANDARDS are being set. ftp://ftp.3gpp.org/specs/
BTW Here's an ex-IDCCer talking about his contribution to 3GPP and 3GPP2...including HSDPA. Someone might want to ring him up !
Agreed. IF the need for UMTS-TDD becomes clearer and more urgent, then it is better for IDCC. IDCC will have a stronger leverage (bigger club; a 4x8 maybe) to sign up licensee.
