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 Measurement Gap Configuration
A Mobile device has to measure the neighboring cells signal and other carrier components. Having a single RF module to control the Mobile manufacturing cost and form factor, device has […]
5G NR System Information
System information is downlink broadcast information transmitted periodically by base station. it is very critical information for a mobile (UE) to connection the Base station (gNB in 5G) in any […]
5G NR Grant Free Dynamic Scheduling – Transmission without Grant
5G networks are expected to support applications demanding ultra-reliable and low latency communication services (URLLC). To support these kind of applications 5G-NR introduced grant free uplink transmission feature a.k.a. Transmission […]
5G NR gNB Higher Layer Split (HLS)
The NG-RAN architecture with a split gNB function is shown in Figure below. Here in NG-RAN a set of gNBs is connected to the 5G Core Network (5GC) through the […]
5G NR Signaling Radio Bearers (SRBs)
SRB stands for Signaling Radio Bearer.”Signalling Radio Bearers” (SRBs) are defined as Radio Bearers (RBs) that are used only for the transmission of RRC and NAS messages. As per 3GPP […]
LTE Handover Latency Calculation (Access Node)
In a cellular system, handover can be defined as a procedure to transfer a User Equipment (UE) and its context from a source cell to a target cell when source cell […]
5G NR RRC State Transitions
5G NR is supposed to inter-work with the legacy technologies like LTE (E-UTRA), UMTS (UTRA) and GSM/GPRS (GERAN). New Radio has introduced a new RRC state called “RRC INACTIVE” to […]
LTE Layer 3 (RRC Layer) Interview Questions
4G LTE Layer 3 is an important layer includes RRC (Radio Resource Configuration) at UE and Base station. In this post is for L3 RRC interview questions with answers. What […]
