How does UE finds CP length in TDD?

Question

Suppose eNB activated SPS for the different LCG, If the corresponding LCG doesn't have Data and implicit release is high. Does UE send the non sps LC data in this grant?

Answer 1

the distance between PSS and SSS are different for normal cp and extended cp.

Comments

that is in FDD, but in TDD signal structure is different right? then how to find?

Answer 2

For frame structure type 2, the primary synchronization signal shall be mapped to the third OFDM symbol in subframes 1 and 6
For SSS mapping, you could check 36.211, it just different mapping scheme.
Actually FDD and TDD also could be distinguished by matching this distance
SSS mapping from 36.211:
