5G NR Dual Active Protocol Stack (DAPS) Handover – 3GPP Release 16
3GPP Definition: As per 3GPP TS 38.300 DAPS Handover can be defined as a handover procedure that maintains the source gNB connection after reception of RRC message (HO Command) for […]
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 RSRP Measurement Report Mapping
In 5G NR, RSRP measurement is performed and reported at Layer 1 (Physical Layer) and Layer 3 (RRC Layer). For example, 5G capable device can provide SS-RSRP measurements at Layer […]
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 […]
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 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 Base Station Types
Introduction to 3GPP Base Station 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: […]
5G NR Cell Search and System Acquisition Procedure
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell. In 5G NR, Cell search concept […]
5G NR Physical Layer Vulnerability- Jamming, Sniffing and Spoofing
3GPP New Radio (NR) will be primary 5G standard moving forward. Cellular networks are no longer fixed to provide commercial services only, these are also being used to emergency service, […]
