@@lteplusplus1225 Adding something more about this.. pls correct me if m wrong..PHICH is transmitted in MIB.PHICH is used for ACK/NACK,but its configuration is present in MIB,Which tells ue abt no. of PHICH group, no. of PHICH RB's,so that ue can calculate PDCCH RB's or CCE 1 PHICH Group=8 PHICH's Thanks🙏
Congrats, finally someone explained this topic very well. Keep uploading videos. Regards!
thanks amed for your feedback.... sure i will upload more lectures in upcoming days.

How RA-RNTI is calculated and why it is used? Is it a unique ID or is it common to all UEs.
RA-RNTI = 1 + Td, for FDD, where Td is the first subframe in which Rach Preamble is sent
@@shankrananddivatagi3786 thanks
please make Rach procedure part 2...
What mask index and resource index in PRACH ?
How UE decode center freq or freq synchronization mentioned in first step?
Nice explain.

Contention can take place if two UEs send same preamble at same time then out of two, rach of one ue will be failed
You are brilliant!!!
please make videos on 5G concepts
Good explanation
Thank you so much! You have explained it really good!
Thanks Falguni for your feedback.
Well before SIB1 MIB1 Is decoded and only after MIB one it decodes SIB1 From where it gets SIB2 , SO YOU MISED MIB
Can you post 5G videos also
will start soon Bill..stay tuned..!!
What is RA_RNTI & HOW IT IS CALCULATED
RA-RNTI is ID in terms of frequency (provided by frequency offset present in sib2) and time (prach configuration index present in sib2)
Bro,Why PHICh used in MIB?
PHICH is present in 1st ofdm sysmbol of all subframes. It is a DL channel and it is used to send ACKNOWLEDGEMENT of data received in UL.
