Event A4 is trigerred when Neighbour becomes better than threshold In 5G NR networks, effective mobility management is crucial to ensure that devices (User Equipment or UE) stay connected with optimal signal quality as they move through various coverage areas.…
In 5G NR (New Radio), the Random Access (RA) procedure is essential for connecting User Equipment (UE) to the network. It facilitates tasks such as initial network access, mobility, and handover. This process involves the exchange of various control messages…
Measurement reporting is crucial for maintaining seamless connectivity and efficient performance in cellular networks. One key event, Event A2, is particularly important when it comes to monitoring the serving cell’s signal quality. This post will cover everything you need to…
Event A1: Serving becomes better than absolute threshold Measurement reporting plays a crucial role in the performance and optimization of 5G networks. One such event that network engineers frequently encounter is Measurement Report Event A1. What is Event A1 in…
Mobility Robustness Optimization (MRO) is a critical feature in 5G NR designed to enhance handover performance and minimize mobility-related failures. Mobility management is essential for providing seamless user experience as UE’s move across cell boundaries in the mobile network. MRO…
3GPP specifications has outlined certain DO’s and Dont’s for the UE when it is in measurement gap period. The procedure outlined in the 3GPP specification deals with the handling of measurement gaps, which are periods during which the UE (User…
Introducing a comprehensive poster detailing the 5G NR Cell Scan Procedure and RACH Procedure. This visual guide offers a step-by-step overview of how UE initiate’s the cell scan procedure upon powering on, delving into the intricacies of 5G cell scanning.…
Beam Failure detection and recovery is a very important procedure in 5G NR. I will try to explain the details in this post with as many details as possible. I will start with giving an overall idea in simple terms…
Discontinuous Reception (DRX) is a power-saving feature designed to extend the battery life of mobile devices. It achieves this by allowing the device to switch off its radio receiver when not expecting network communication, thus reducing power consumption significantly. DRX…
What is NCD-SSB and why is it needed and what’s the use case here ? In Release-15 the term CD-SSB was referred to the SSB that accompanies RMSI i.e. the MIB of the CD-SSB carries information of the scheduled SIB1…
