5G NR SINR Measurement and Its Mapping

Introduction SINR is Singal to Interference Noise Ratio is a measure of signal quality. It can be defined as the ratio of  wanted signal strength and the unwanted interference plus […]

5G Carrier Aggregation – Bandwidth Classes

Carrier Aggregation (CA) increases the bandwidth by combining several carriers. Each aggregated carrier is referred to as a Component Carrier (CC). 5G NR CA supports up to 16 contiguous and […]

5G NR RSRQ Measurements and Its Mapping

The RSRQ (Referece Signal RecivedQuality) is a measurement performed by the UE to know the Quality of recieved Reference Signals. In 5G NR, RSRQ can be measurement for SS-Reference Siganls […]

5G NR BFR – Beam Failure Recovery

The 5G communication specially at higher frequencies or mmWave is using Massive MIMO with Beamforming. Beamforming is a signal processing technique that allows gNB send targeted beams of data to […]

5G NR Downlink HARQ Codebook

In 5G NR, 3GPP specification has defined HARQ Codebook  to provide the feedback to base station for Downlink data transmission i.e., PDSCH Data. UE Sends the ACK/NACK for corresponding PDSCH […]

5G NR SS-RSRP Value Measurement Mapping

UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management procedures. RSRP measurement generated and reported at both Layer 1 […]

5G NR Numerology – Subcarrier Spcaing (SCS)

In LTE, there is only type of numerology or subcarrier spacing (15 KHz), whereas in NR, multiple types of subcarrier spacing are available e.g 5G NR supports subcarrier spacing of […]
