NR-NR Dual Connectivity (NR-DC)
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 in 5G NR
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…
Self Contained Slot in 5G-NR?
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…
Beam Correspondence in 5G-NR
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?
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…
5G-NR Physical Layer Specifications overview
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…
5G NR Timers and Constants
5G NR UE Timers and Constants Below is the list of all the UE Timers and Constants in the 5G NR. All descriptions have been copied from the spec and have not been modified to keep the original information handy…
DAPS Handover: UE Functionality
During the NR Registration procedure, UE will include its support for Dual Active Protocol stack (DAPS) Handover in the UE Capability message. If there is no support for DAPS from UE, then the network will not configure DAPS handover for…
