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…
DAPS Handover: UE Capability Information
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…
DAPS Handover: Release-16 Call flow
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…

What is N26 Interface in 5G and what’s its importance?
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…
Difference between BLER for Radio Link Management and BLER in Data throughput?
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…
What is the 10% BLER target in LTE and NR?
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…
Radio Link Monitoring in 5G-NR
A UE when it is connected to the network, it needs to continuously monitor the Radio link for reliable communication. The UE monitor’s the downlink link quality based on the reference signal in order to detect the downlink radio link…
