5G NR Physical Cell ID (PCI) Planning
Each 5G NR cell corresponds to a Physical Cell ID (PCI) and it is used to distinguish cells on the radio side. The PCI planning for 5G NR is very […]
5G Identifiers SUPI and SUCI
In telecommunication systems, network operator allocate to each SIM card a unique identifier, known up to the 4G as an IMSI (International Mobile Subscriber Identity) and for the 5G as […]
Open RAN (O-RAN) Reference Architecture
The O-RAN Reference Architecture is designed to enable next generation RAN infrastructures. It is designed with the principles of intelligence and openness, the O-RAN architecture is the foundation for building […]
5G System Connection Management: CM-Idle and CM-Connected
When a Mobile wants to communicate with 5G core network, as it first time switched-on or because it was in idle state for some time and network removed the resources […]
5G Network Sharing: Concept, Benefits and Architectures
The deployment of a new telecommunication network and its operation can lead to very high costs and a long entry time to business for a operator. Sharing the network infrastructures […]
5G NR Global Unique Temporary Identifier (GUTI)
5G Global Unique Temporary Identifier [5G – GUTI] is a core network temporary identifier and allocated by Access and Mobility Management function [AMF] to the UE. GUTI is 80 bits […]
5G NR Grant Free Dynamic Scheduling – Transmission without Grant (TWG)
5G networks are expected to support applications demanding ultra-reliable and low latency communication services (URLLC). To support these kind of applications 5G-NR introduced grant free uplink transmission feature a.k.a. Transmission […]
5G NR Transmitted Signal Quality: Time Alignment Error [TAE]
Transmitted signal quality specify how much the transmitted signal deviated from an ideal signal in terms of frequency domain, timer domain or modulation property. The impairments on the transmitted signal are […]
5G NR Transmitted Signal Quality : Frequency Error [Fe]
Transmitted signal quality specify how much the transmitted signal deviated from an ideal signal in terms of frequency domain, timer domain or modulation property. The impairments on the transmitted signal […]
5G NR Base Station Classes
3GPP specification for 5G NR defines the three classes for base station namely, Wide Area Base Station, Medium Range Base Station and Local Area Base Station. These classes are corresponding […]
