The concept of a PDU Session in 5G can be compared to the “EPS Bearer” in LTE. It is a critical component that provides end-to-end user plane connectivity between the User Equipment (UE) and the Data Network Name (DNN). A PDU Session in 5G is…
MSG2 RACH Failure Common Causes in 5G NR: The Random Access Channel (RACH) procedure in 5G NR is a critical part of establishing a communication link between the (UE) and the gNB. MSG2, which is the Random Access Response sent…
Event A5 (SpCell becomes worse than threshold1 and neighbour becomes better than threshold2) Measurement Event A5 is a critical event in 5G NR, used by UE to ensure optimal handovers between cells. Measurement Event A5 is triggered when: This dual…
RNTI Values In 5G NR, RNTI (Radio Network Temporary Identifier) values are super important for figuring out different types of communication in the network. They help us tell apart control and data transmissions, so we can manage resources efficiently. Each…
What is Contention Resolution in 5G NR RACH? The Contention Resolution Identity (MSG4) is a crucial part of the Random Access procedure in 5G NR. Contention resolution in 5G occurs when multiple UEs attempt to access the network simultaneously, causing…
Measurement reporting is a critical aspect of mobility management in 5G NR (New Radio) networks. Among the various events defined by 3GPP, Event A3 plays a crucial role in enabling seamless handovers between cells. In this blog post, we will…
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…
