    Hi,
    As per my knowledge, in 10 ms TTI it is transmitted 32 kbps and it is consumed 1 CE.
    In 2 ms TTI it is transmtted 160 kbps and consumed 8CE.
    In 2ms TTI ,for max throughput 2X2+2X4 SF . so SF2 it transmitted 1.92mbps and SF4 it transmitted 960 kbps .it will get around 5.7 mbps .
    and 96 CE is consumed to get this much speed.

    Thank for your responce, but my main qestion was not about HSDPA or HSUPA, main qestion is how does TTI influent on throughput (if influent )

    with 2ms TTI you can respond faster to Link conditions. So if you have a link which is good you can get higher throughput due to quick allocation. Hence we could get better than average bit rates and hence gain in throughput.

    So i'm i rigth, if we are in laboratory and in excelent conditions, possible to say, that it doesn't matter which TTI (2 ms or 10 ms) we use?

    it is like they´ve explained before... that it frees up codes to be used...

    Another way of looking at it is that you more HARQ instances that can be defined with 2ms TTI compared to a 10ms TTI.
