Pre-configured Measurement Gap (Pre-MG) Cheat Sheet Pre-configured Measurement Gap 3GPP TS 38.133 Section 9.1.7 Purpose / Why It Matters • Pre-MG allows UE to be configured with a measurement gap pattern that can be dynamically activated/deactivated without full RRC reconfiguration…
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 utilizes the N26 interface which enables the…
In the evolution from 4G to 5G, interworking between the Evolved Packet System (EPS) and the 5G System (5GS) is a critical architectural component. 3GPP specifications define precise mechanisms to handle how a User Equipment (UE) manages its registration state…
PDCCH order is a way of network instructing the UE to trigger a Random access Procedure. Typically RACH is triggered by UE and there are a number of reasons why RACH can be triggered by UE. But network can force…
During Handover from Source Cell to Target cell, if both the Source and target cell use same Configurations for certain Physical and control channels, the target cell can re-use the same configuration and modify the parameters which are different at…
