Hello Experts.
What information is present in PRACH Preamble (Msg1)?
Is if just zad-off chu sequence or more information is encoded info it?
Or
What information does gNB decode from this Prach Preamble (Msg1)?
Msg1 has - TCP+TSeq+TGT.
Tcp - cyclic prefix
Tseq - random sequence generated from zaddoff basis u long or short seq
TGT - guard time.
So msg1 sent with zaddoff chu sequence along with msg cause.
I meant to say what physical message is sent using this PRACH Preamble?
Does it give any information to gNB? (These sequences)
These sequence gives indication to gnb like any ue wants to access gnb service.
So preamble just kind of indication to access service.
No other role.
