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…
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…
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…
NR-DC is the variant when the UE is connected to one gNB that acts as a Master Node and one gNB that acts as a Secondary Node. The Master Node is connected to 5GC while the Secondary Node is connected…
PDCCH order is one of the reasons for RACH trigger in both LTE and 5G-NR. If the network detects that there is DL Data to be sent to UE in its MAC Buffer and there is a UL synchronization issue…
In 5G New Radio (NR), “time slot” defines a specific time interval within the radio frame structure that facilitates data transmission and reception. Time slots play a crucial role in organizing the data flow in wireless communication systems like 5G…
3GPP Defines Beam correspondence as to the ability of the UE to select a suitable beam for UL transmission based on DL measurements with or without relying on UL beam sweeping. The beam correspondence requirement is satisfied assuming the presence…
Can the Same 5G Cell be used for NSA and SA ? The Short answer is Yes. The network can configure the same cell as an NSA and SA cell. Initially, the operator might deploy the cell as an NSA…
The Physical layer specifications of 5G-NR are spread across six Specification documents and one general description document; The relation between Multiple PHY Layer specifications is illustrated below. TS 38.201: 5G NR Physical layer; General description The scope of the document…
