Voice Over NR (VoNR Call Flow)
We are seeing 5G Stand Alone (SA) data services are rolling out throughout the world, it is very much essential for MNOs to provide services such as Voice/Video calls. To […]
Open Midhaul F1 Interface F1-C and F1-U
The F1 interface connects a gNB CU to a gNB DU. This interface is applicable to the CU-DU Split gNB architecture. The control plane of the F1 (F 1-C) allows […]
5G NR HO Setup: Handover Testing in Cabled Setup
Handover, or handoff in 5G NR or 4G LTE happens when a Data/Voice call is transferred from one cell to the an adjacent cell as the Mobile user moves through […]
Marvell’s O-RAN Solutions Overview
There one more name to the OEM vendors for O-RAN products and name is Marvell Semiconductors. They announced their 5G O-RAN portfolio with a vRAN platform. Open RAN architectures enable […]
5G O-RU Digital Front Solution (DFE) Solution from Xilinx
In our last post, we discussed the the reference architecture for O-RAN Radio Unit (O-RU) and introduce the different subsystem e.g Synch and Fronthaul Transport, Lower PHY, Digital Front End […]
O-RAN – Radio Unit (O-RU) Reference Architecture
The Radio Unit (RU) purpose is to convert radio signals sent to and from the antenna to a digital signal that can be transmitted over the fronthaul to Distributed Unit […]
5G NR QoS Architecture, QoS Attribute and QoS Flow
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 rate, […]
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 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 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 […]
