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 […]
