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 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 […]
5G NR RSRP Measurement Report Mapping
In 5G NR, RSRP measurement is performed and reported at Layer 1 (Physical Layer) and Layer 3 (RRC Layer). For example, 5G capable device can provide SS-RSRP measurements at Layer […]
NB IOT Peak Data Rate Calculation
We have seen in different literature that Narrow Band IOT (NB-IOT) release 13 technology peak downlink data rate is 170 kbps and pplink data rate is 250 kbps, do know […]
5G mmWave 28 GHz Band Link Budget – n257
The combination of 5G NR technology and millimeter wave bands pioneer a new level of mobile performance with ultra-high speeds and low latencies. Momentum behind 28 GHz is growing, with […]
5G NR Measurement – Serving Cell and Neighbor Cell
In 5G NR, for the procedures such as handover to a stronger cells or adding a new Carrier Component (CC) in the case of Carrier Aggression, it is required to […]
5G NR Antenna Port – Logical and Physical Antenna Mapping
Downlink multi-antenna transmission is a key technology of 5G NR. Signals transmitted from different antennas ports will experience different “radio channels” even if the set of antennas are located at […]
5G NR Network Relationship – Neighbor Planning
In any telecommunication technology starting from 2G to 5G, Neighbor relation or to say Neighbor planning is an important activity. Neighbor relation information is very critical for cell re-selection while […]
5G NR Physical Cell ID (PCI) Planning
Each 5G NR cell corresponds to a Physical Cell ID (PCI) and it is used to distinguish cells on the radio side. The PCI planning for 5G NR is very […]
5G NR Transmitted Signal Quality: Time Alignment Error [TAE]
Transmitted signal quality specify how much the transmitted signal deviated from an ideal signal in terms of frequency domain, timer domain or modulation property. The impairments on the transmitted signal are […]
