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 Standardized QoS Identifier (5GQI) to QoS Characteristics Mapping
Standardized 5G QoS Identifier (5QI) values are specified for services that are assumed to be frequently used in 5G networks and thus benefit from optimized signalling by using standardized QoS […]
5G NR QoS characteristics
5G QoS characteristics describe the packet forwarding treatment that a QoS Flow receives edge-to-edge between the UE and the UPF in terms of the following performance characteristics: Resource Type (GBR, […]
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 RACH Preamble Types: Long and Short Preambles
A preamble is send by UE to gNB over PRACH channel to obtain the UL synchronization. Similar to LTE, in 5G NR there are 64 preambles defined in each time-frequency […]
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 – What Makes It Different & How Does It Impact Your Business – Mark Hearn CEO Network Control
You may see ads from your cell provider touting the coming of 5G, and you’re wondering what it is and what makes this different from the previous versions of cellular […]
5G End to End KPI – Accessibility, Integrity and Utilization
A Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively a network is serving the user. In simple terms we can say KPIs describe the fitness level […]
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 […]
