5G NR Dual Active Protocol Stack (DAPS) Handover – 3GPP Release 16
3GPP Definition: As per 3GPP TS 38.300 DAPS Handover can be defined as a handover procedure that maintains the source gNB connection after reception of RRC message (HO Command) for […]
5G NR NSA Network Access Issues and Possible Root Cause
Many of the operator across the global has started providing 5G services using NSA mode with Option 3.x . In NSA mode the network topology consist of a LTE cell, […]
5G NR Stand Alone (SA) Requirement Analysis to Inter-Op with 4G
5G NR deployment option 2 as known as Stand Alone (SA) Architecture where 5G gNB connect to 5G Core network for all signalling and Data sessions. 4G LTE will coexist […]
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 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 […]
