5G NR Inactive-RNTI (I-RNTI) for RRC_INACTIVE State
In 5G NR, 3GPP specification has introduced an RRC state as RRC_INACTIVE state. The aim of RRC_INACTIVE state is to achieve power saving with acceptable access latency, and is suitable […]
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 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 […]
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 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 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 Types
As per 3GPP specification TS 38.104, the NR Base Station can be classified in following categories considering conducting (cabled) and radiating (OTA) requirement reference points: Base Station type 1-C Base […]
5G End to End KPI – Accessibility, Integrity and Utilization
A Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively a network is serving the user. In simple terms we can say KPIs describe the fitness level […]
5G Key Performance Indicator Definitions Template by 3GPP
3GPP specification TS 28.554 has given a template for end to end KPIs of 5G System. This template is valid for for both NR-Radio Access Network and Core Network. Below […]
