An orthogonal frequency division multiplexing (OFDM) technique that uses cyclic prefixes (CP) instead of null guards, protecting OFDM signals from intersymbol interference (ISI).
An optional modulation format used in the uplink in 5G NR. DFT-s-OFDM uses the mathematical concept of discrete Fourier transform to encode digital data on
A new radio interface specified by the 3GPP consortium and introduced with LTE in 2008. It was designed to meet ever-increasing data transfer rates while
A standard that sets the requirements for 5G networks, devices, and services. IMT-2020 was developed by the International Telecommunications Union (ITU) Radiocommunication Sector in 2015.
Part of 3GPP Release 13 and a feature of LTE Advanced Pro. It uses carrier aggregation in both the unlicensed (5 GHz) and licensed spectrums
An application of multiple-input / multiple-output (MIMO) technologies where the base station communicates with two or more UEs simultaneously.
The 5G next generation core network. NGC or NGCN is the part of the network that provides services to mobile subscribers through the radio access
An orthogonal frequency division multiplexing scheme that uses pulse-shaped multicarrier waveforms, offering comparatively high waveform robustness with low out-of-band emissions and interference.
The average of the power of the resource elements that carry the synchronization signal.
A measurement of the received quality of the synchronization signal.
The power of the synchronization signal divided by the sum of the interference from competing signals and the background noise present.
An application of multiple input and multiple output (MIMO) technologies for wireless communication, in which the base station communicates with only one UE during the
A form of orthogonal frequency division multiplexing (OFDM) modulation that improves out-of-band (OOB) characteristics by filtering the frequency band.
An orthogonal frequency division (OFDM) multiplexing technique that uses an arbitrary deterministic sequence as the guard interval rather than the random cyclic prefixes used in
An orthogonal frequency division multiplexing (OFDM) technique where each symbol is windowed and overlapped in the time domain, reducing the spectral sidelobes.
Represents a secure all-IP mobile broadband system for wireless devices, going beyond mobile phones systems marketed as 3G; referenced as 4G or 4.5G.
A program led by Working Party 5D of ITU’s Radio Communication Sector (ITU-R) to develop “IMT for 2020 and Beyond,” setting the stage for 5G
