DevOps – Jenkins Inteview Questions
This post is we have listed most frequent asked question during the Interiew. Jenkins is an open source automation tool with plugins built for Continuous Integration purpose. Jenkins is used […]
5G NR NSA Network Access Issues and Possible Root Cause
Many of the operator across the global has started providing 5G services using NSA mode with Option 3.x . In NSA mode the network topology consist of a LTE cell, […]
5G NR Transport Block Size (TBS) Calculation
Transport Block in 5G NR, is nothing but the payload which is passed between the MAC and Phy Layers, specifically for the shared data channel such as PDSCH and PUSCH. […]
5G NR – Msg2 Random Access Response (RAR) – SA Mode
In 5G NR, the initial access include down-link synchronisation and up-link synchronisation procedures. Downlink synchronisation can be achieved after decoding Minimum System Information (SSB-MIB) and Remaining System Inforatmion (RMSI- SIB […]
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 […]
Features Comparison: NB-IoT UE Vs LTE UE
Table here list the features comparison between Narrow Band (NB) – IoT UE and Long Term Evolution (LTE) UE Features Narrow Band IoT UE LTE UE Master Information Block (MIB) […]
Robust Header Compression – ROHC
ROHC is a header compression protocol/algorithm that can be used compress the header of different IP packets. In normal case without compression IPv4 header is 40 bytes and IPv6 header […]
TTI Bundling for better HARQ and Latency
TTI bundling enables a data block to be transmitted in consecutive TTIs, which are packed together and treated as the same resource during the scheduling process. TTI bundling makes use […]
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 Reference Signals (DMRS, PTRS,SRS and CSI-RS)
To increase protocol efficiency, and to keep transmissions contained within a slot or beam without having to depend on other slots and beams, NR introduces the following four main reference […]
