5G NR Cell Search and Synchronization
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell. In 5G NR, Cell search concept […]
5G NR QoS Parameters
3GPP specification 23.501 defined the following 5G QoS Parameters as part of QoS Implementation. 5G QoS Identifier (5GQI) Allocation and Retention Priority (ARP) Reflective QoS Attribute (RQA) Notification Control Flow […]
5G NR Total Transmit Power | Maximum Cell Transmit Power | Reference Signal Power
The Reference Signal Power and the total transmit power of the cell can calculated by using a single channel power using following formula, Maximum Transmit Power indicates the transmit power […]
5G NR Physical Layer Vulnerability- Jamming, Sniffing and Spoofing
3GPP New Radio (NR) will be primary 5G standard moving forward. Cellular networks are no longer fixed to provide commercial services only, these are also being used to emergency service, […]
5G NR User Plane Latency
The definition of user plane latency as per 3GPP TR 38.913, is “the time to successfully deliver an application layer packet/message from the radio protocol L2/L3 SDU entering point to […]
5G NR Control Plane Latency
The latency performance of a communication system is analyzed for both control plane and user plane. In this post lets discuss about control plane latency. The definition of control plane […]
5G Key Performance Indicator Definitions Template by 3GPP
3GPP specification TS 28.554 has given a template for end to end KPIs of 5G System. This template is valid for for both NR-Radio Access Network and Core Network. Below […]
What parameters impact the EVM of transmitter chain ?
The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation […]
Virtual Network Function (VNF) Definition, Architecture and Design
A Network Function (NF) is an element within a network with well defined external interfaces and functional behavior e.g. DHCP , Firewall, SAE Gateway, MME, eNodeB. Virtual Network Function (VNF) […]
NFV Management and Orchestration [MANO] Key Performance Indicators [KPIs]
NFV management and orchestration (MANO) systems are being developed to meet the agile and flexible management requirements of virtualized network services in 5G Networks. Regarding this, ETSI ISG NFV has […]
