Actually i am trying to learn RACH procedures and getting lots of hurdles to understand. I am posting my queries whatever is coming to my mind so that i will get the descriptive answers. I hope someone will help me here to learn it. Thanks in advance.

In spec it is being told that it a preamble format based offset but I am not getting what the data preamble actually is?
