SpletIt set the TEMPORARY_C-RNTI to the value received in the Random Access Response UE switches to 4 Step RACH process and continues the RACH procedure until successful. If the UE receives Successful RAR, it transmits a PUCCH HARQ-Ack, the PUCCH id to send the HARQ-ACK value is received in the RAR message. SpletIn the Release-16 NR version, 3GPP Introduced a new 2-Step RACH procedure that aims to improve the overall latency of the RACH procedure. Now there are two RACH procedures and 3GPP has categorized the it into two types. Type-1 Random access procedure (4-Step-RACH) and. Type-2 Random access procedure (2-Step-RACH).
