SSC Modes – Session and Service Continuity in 5G
In any telecom technology one of the key feature requirement is data session and service continuity to enusre the uninterrputed service experience to the users irrespective of any change of […]
5G Voice Services Implementation Options
Voice over NR (VoNR): UE camps on NR cell. Voice and data services are transferred via NR. When UE moves to the edge of NR coverage, the voice service is […]
5G NR RLC – UM Mode Data Transmission
In 5G NR, RLC has 3 different modes of operations TM, UM and AM and each of the mode can transmit and receive data, serving different logical channels as per their requirement. This post provides […]
5G NR Layer 2 – Radio Link Control (RLC) Overview
5G RLC overall functionality is almost same as LTE RLC. In 5G also, RLC has 3 different modes of operations and each of the mode can transmit and receive data, […]
5G QoS Architecture, QoS Attribute and QoS Flow
Introduction Quality of service (QoS) refer to the measurement of the overall performance of a service experienced by the users of the network. To quantitatively measure the QoS packet loss, bit […]
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 […]
