IN 5G-NR UE’s operating in RRC_Connected mode can be categorized into two types of mobilities Cell level mobility and Beam Level Mobility which are network controlled procedures. In Release-15 3GPP has introduced the inter-gNB handover procedure which is similar to…
RACH Failure can happen due to Multiple issues and there might be multiple reasons, I have listed down a list of RACH Failure reasons that can happen in 5G-NR. RACH process is a PHY/MAC Level procedure, but the RACH Configuration…

N26 interface is an inter-Core Network interface between the MME and 5GS AMF in order to enable interworking between EPC and the NG core. Inter-RAT Mobility procedures involving mobility between LTE-EPC and 5G-NR-5GS utilize the N26 interface which enables the…
What’s the difference between BLER for Radio Link Management and BLER in Data throughput? A Block Error Ratio(BLER) is defined as the ratio of the number of erroneous blocks received to the total number of blocks sent. BLER = Number of…
There is a Buzz word which everyone says that BLER should be under 10%, but 10% of what? There are two scenarios where BLER calculation is taken into account – BLER Target for Radio Link Monitoring– BLER Target for PDSCH…
The Radio Link Monitor (RLM) is a crucial component in ensuring reliable communication in 5G New Radio (NR) networks. It evaluates the quality of the radio link and interacts with the RRC layer to detect potential failures. Below is a…
In the intricate world of 5G networks, the Random Access Channel (RACH) serves as a vital gateway for User Equipment (UE) to establish initial communication with the network. While RACH is commonly associated with UE transitions from idle mode to…
