5G NR Measurement Configuration: Meas Object, Report Config, Meas ID
During UE attach, after a radio bearer is set up, the eNB (in NSA Mode) or gNB (in SA Mode) delivers measurement configurations to the UE based on the mobility […]
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 Inactive-RNTI (I-RNTI) for RRC_INACTIVE State
In 5G NR, 3GPP specification has introduced an RRC state as RRC_INACTIVE state. The aim of RRC_INACTIVE state is to achieve power saving with acceptable access latency, and is suitable […]
Motivation Behind Having Multiple Numerology in 5G NR
Talking about numerology, as we know LTE has single subcarrier spacing equal to 15khz, but here in NR, we have multiple numerologies and those are represented by Greek letter µ. […]
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 […]
5G Network RF Planning – Link Budget Basics
The link budget is the calculation of total gain and loss in the system to conclude the received signal level (RxSL) at the receiver (UE). The received signal level is […]
5G Network Sharing: Concept, Benefits and Architectures
The deployment of a new telecommunication network and its operation can lead to very high costs and a long entry time to business for a operator. Sharing the network infrastructures […]
