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 […]
5G NR Interfaces X2/Xn, S1/NG, F1 and E1 Functions
In LTE networks, X2 and S1 interface are defined as an interfaces between RAN nodes and between RAN and Core Network. 5G is expect to operate in two modes as […]
NR Resource Block Definition and RBs Calculation
Resource Block Definition One NR Resource Block (RB) contains 14 symbols in time domain and 12 sub-carriers in frequency domain similar to LTE. In LTE resource block bandwidth is fixed […]
NR Sounding Reference Signal (NR-SRS)
In NR there are two types of Reference Signal in UL which gives information about the channel quality. DMRS:- Demodulation Reference Signal SRS:- Sounding Reference Signal With the help of […]
Multi Carrier Cell Re-selection in LTE
Cell Re selection is a procedure used to change the cell after the UE is camped on a cell and stays in the Idle mode.This procedure is used to let […]
5G NR BWP Types and BWP Operations
In 5G New Radio the cell bandwidth is expected to be large compared to LTE, but a UE’s receive and transmit bandwidth is not necessarily required to be same as […]
5G NR Radio Network Temporary Identifier (RNTI)
RNTI stands for Radio Network Temporary Identifier. RNTIs are used to differentiate/identify a connected UE in the cell, a specific radio channel, a group of UEs in case of paging, […]
5G Self Backhaul- Integrated Access and Backhaul
Self-Backhauling Concept Self-backhauling defined as when the access i.e. Base station – Mobile and the backhaul (Base Station to Base Station or Base Station to Core Network) share the same […]
5G NR Bandwidth Part (BWP)
A Bandwidth Part is a contiguous set of physical resource blocks (PRBs) on a given carrier. These RBs are selected from a contiguous subset of the common resource blocks for […]
