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 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 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 NR Cell Search and Synchronization

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 User Plane Latency

The definition of user plane latency as per 3GPP TR 38.913, is  “the time to successfully deliver an application layer packet/message from the radio protocol L2/L3 SDU entering point to […]
