Motivation Behind Having Multiple Numerology in 5G NR
Talking about numerology, as we know LTE has single subcarrier spacing equal to 15khz, but here in NR, we have multiple numerologies and those are represented by Greek letter µ. […]
5G NR Network Relationship – Neighbor Planning
In any telecommunication technology starting from 2G to 5G, Neighbor relation or to say Neighbor planning is an important activity. Neighbor relation information is very critical for cell re-selection while […]
5G NR Quasi-Colocation Concept, Types and Application
Two signals transmitted from same antenna port shall experience the same radio channel, where as transmitting it from two different antenna ports shall experience different radio conditions. But there can […]
What is Prometheus?
Prometheus is an open source software application used for event monitoring and alerting. It records real-time metrics in a time series database (allowing for high dimensionality) built using a HTTP […]
5G NR Antenna Ports – Logical and Physical Antenna Ports
In 5G NR or 4G LTE, Multiple Input-Multiple Output (MIMO) transmission is a key technology specifically in downlink. Signals transmitted from gNB/eNB via different antennas or signals subjected to different […]
5G Network RF Planning – Link Budget Basics
The link budget is the calculation of total gain and loss in the system to conclude the received signal level (RxSL) at the receiver (UE). The received signal level is […]
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 […]
What is eCPRI, how it contributes to 5G and Open RAN?
The Common Public Radio Interface (CPRI) is an industry cooperation aimed at defining publicly available specifications for the key internal interface of remote radio head (RRH) or Radio Equipment (RE), […]
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 […]
5G NR System Information
System information is downlink broadcast information transmitted periodically by base station. it is very critical information for a mobile (UE) to connection the Base station (gNB in 5G) in any […]
