RACH is triggered in different scenarios, ensuring smooth connectivity and network reliability. Types of RACH Trigger in 5G NR 1. Initial Access – When a UE connects to the 5G network for the first time or after being powered on. 2. Handover – When the UE moves from one cell to another and needs to establish a new connection. 3. Beam Failure Recovery – When a beam link is lost, the UE triggers RACH to re-establish communication. 4. Radio Link Failure (RLF) Recovery – If the connection between the UE and gNB is lost due to poor signal, RACH is triggered. 5. UL Synchronization Loss – If the UE loses uplink synchronization, it triggers RACH to re-align with the gNB. 6. Scheduling Request (SR) Failure – If the UE fails to get an uplink grant, it may trigger RACH to request resources again. RACH can be either Contention-Based (CBRA), where multiple UEs compete for access, or Contention-Free (CFRA), where dedicated resources are assigned by the network. These mechanisms help optimize network entry and mobility management in 5G. In this video, we will break down the RACH trigger types, their role in 5G NR, and how they impact network performance and user experience.
