The RA-RNTI associated with the PRACH where Random Access Preamble is transmitted can be computed follows: RA-RNTI= 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id.
What is RA-Rnti in 5G?
Random Access – Radio Network Temporary Identifier. As part of the E-UTRA access procedure the UE will probe the system with Random Access Preambles. On receiving these the eNB generates a RA-RNTI to effectively schedule the response.
What is rapid in Rach?
Random Access Preamble Identifier. This is used by the E-UTRA MAC layer and relates to the 6bit access preamble identifier which was initially used by a UE accessing the eNB on the PRACH. Effectively it forms part of the contention resolution procedure.
What is Rnti in LTE?
RNTI stands for Radio Network Temporary Identifier. As the name implies, it is a kind of Identification number.
What is message 3 in 5G?
The MSG3 is very first PUSCH transmission scheduled by MSG2 with the RAR UL grant. A UL grant includes scheduling information for frequency hopping, frequency and time domain resource allocation, MCS, and transmit power control necessary information required for MSG3.
