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 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 RRC Timers, Counters and Constants

5G NR radio resource control (RRC) has introduced following listed timers, counters and constant for reliable functioning of procedures like RRCsetuprequest, RRCreestablishment, RRCresume, RRCsuspend etc. RRC timer indicates the timer […]

5G NR Quasi-Colocation Concept, Types and Application

Two signals transmitted from same antenna port shall experience the same radio channel, where as transmitting it from two different antenna ports shall experience different radio conditions. But there can […]
