5G NR Measurements: RSRP, RSSI, RSRQ and SINR

In LTE, the UE measurements are done for RSRP, RSRQ and SNR associated with CRS (Cell Specific Reference Signal) .  5G NR uses  SS (Synchronization Signal) and CSI (Channel State […]

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 […]

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 […]
