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 RA-RNTI Calculation

A 5G UE picks a random preamble for RACH procedure to get the uplink synchronisation. The preamble is referenced with an ID know as  RAPID (Random Access Preamble ID). 5G […]

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 […]

5G NR RRM Measurement Requirements

In 5G NR, the Sync Signal/PBCH block (SSB) burst is consists of multiple SSBs. These multiple SSBs are associated with the different SSB indexes and with the different transmission beams […]

Multiplex Access Technique in 5G

Multi-path propagation in a radio signal transmission causes time delays, signal distortions, and so on. Let us discuss basic theories of multiple access techniques utilized in 1G-to-5G systems for solving […]

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 […]
