5G NR SS-RSRP Value Measurement Mapping

UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management procedures. RSRP measurement generated and reported at both Layer 1 […]

5G NR SCG Failure and Radio Link Failure

For the purpose of Radio Link Failure (RLF), the UE physical layer monitors the downlink radio link quality of the primary cell for indicating out-of-sync / in-sync status indications to […]

4G LTE Important QXDM Log Packets

QXDM is most widely used tool in wireless 4G,5G technology to capture Qualcomm based Mobile signalling and data details logs for debugging purpose. Whether it is Field testing or Lab […]

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 System Information Type#3 – SIB 3

In 5G NR, SIB3 contains neighboring cell related information relevant for intra-frequency cell re-selections only. It includes cells with specific re-selection parameters and blacklisted cells information. Characteristics of NR System […]

5G NR System Information Type#2 – SIB 2

In 5G NR, System Information Block Type 2 or SIB2  provides information which is common to intra frequency , inter frequency and inter-system cell (NR – LTE) reselection. It also […]
