5G NR PRACH Power Control: MSG1 Tx Power – Open Loop Power
In any wireless System, when a device (UE) needs to get access it has to send a signal or preamble (MSG1) to base station (gNB), then energy is needed. One […]
Iperf : A Tool for Network Testing
Iperf or IP performance is a utility for testing network performance and its tuning. It is a cross-platform (windows, linux) tool which can provide standardized measurement results for any network […]
Open RAN Integration – Where We Today
Open RAN is being deployed by multiple Service Providers around the world. These deployment are large scale deployments in some of the largest countries in the world. In Open RAN […]
O-RAN Distributed Unit (O-DU) Reference Architecture
The O-RAN or Open Distributed Unit (O-DU) is a commercial off-the-shelf (COTS) edge servers that can function as baseband processing unit to handles high PHY layer, MAC and RLC layer […]
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 […]

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 […]
3GPP Evolution for MIMO
Released 3GPP standards on MIMO are shown in below image. As you know, Coordinated Multipoint (CoMP) is a type of Cooperative MIMO, in which data and channel state information (CSI) are […]
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. […]
3GPP Release 12
3 GPP Release 12 was largely completed on-time in March 2015, with a few exceptional features allowed an extension to later in the year. Release 12 builds on the innovations in […]
