    Default LTE why Ts=32.55 ns ???

    Hi Guys,
    I'm studing 4G but I can not understand why Ts is about 32.552083 ns.
    Please is there anyone who could explain me why Ts has this value ?

    T s=1/(15000×2048)s=1/30720000s=32.552083ns
    where
    15Khz is subcarrier band in LTE
    2048 : block size

    look for 3gpp 36.211.

    And what if we have 10Mhz bandwidth and FFT size 1024?

    And one more question,if we have Ts which depends on sampling rate,so does it mean that timing advanced also depends on this variable,because Ta=16Ts?
