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 RACH Procedure Overview – CBRA & CFRA

When we want to connect a UE to 5G network, it has to synchronize in downlink as well as in uplink. Downlink synchronization is obtained after successfully decoding SSB, In […]

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 […]
