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 36.321 it is being told that while deciding upon which preamble group to choose for RAP delta preamble is used.
In spec it is being told that it a preamble format based offset but I am not getting what the data preamble actually is?
