5G NR RACH process – Msg3/4 and Contention Resolution

5G NR RACH process – Msg3/4 and Contention Resolution

Msg3 and Msg4 are used for contention resolution. The uplink time synchronization are completed in Msg1 and Msg2. The purpose of Msg3 and Msg4 is to identify the C-RNTI for the subsequent data transmission. During CBRA, there are chances that multiple UE may use the same …

5G NR RACH process – Msg1 – RA-RNTI calculation and Power control

5G NR RACH process – Msg1 – RA-RNTI calculation and Power control

Once the RACH configuration and preambles are selected, it is to be sent out to the available PRACH occation. For that RA-RNTI is to be calculated according to the PRACH occation. In this chapter we shall see: 1. What is the power required to send Msg1 …

5G NR Random Access Resource Selection

5G NR Random Access Resource Selection

In this chapter we shall see where the UE can get the resources for PRACH transmission. Before UE can send a PRACH, it needs to select an SSB then UE will selects an SSB with SS-RSRP above rsrp-ThresholdSSB for PRACH transmission. For normal RACH procedure, UE …

5G NR: Different Types of RACH procedures and triggers for RACH procedure

5G NR: Different Types of RACH procedures and triggers for RACH procedure

RACH: Random Access procedure is used for uplink synchronization and RRC Connection. UE will get downlink synchronization after successfully decoding SSB. Before Rel 16, there was only 1 type of RACH that is similar to LTE i.e 4-step RACH. But after Rel-16, 3GPP introduced new 2-step …
