Data or LTF in Channel Estimation

How does it works while wo choose "Data" in "Channel Estimation"?

Specific datas are transmitted in the LTF so that the channel coefficient can be calculated with received datas.

The data part of a packet doesn't contain known information, how does "Channel estimation" work? Pilot subcarriers are used to do frequency synchronization according to ieee standards.

I found "LTF/Data" configuration both in IQXel and NI instruments. Does it means there exist a standard method to do channel estimation with "Data"?
