5G Networks: Use-Cases
By Vikram Singh
5G networks are designed to support many use-cases for variety of scenarios and
terrains. These use-cases have different latency, date-rate and scale (number
of devices) quality of service requirements. The requirements are defined in
terms of bit/block/packet error rate, throughput (spectral efficiency, energy
efficiency), latency, power consumption (complexity of algorithms), scale
(variation of QoS with number of devices) and coverage analysis. Some of these
use-cases are listed below:
- Vehicle to everything (V2X)
- Non-terrestrial Networks
- Cellular Positioning
- Internet of things devices communication
- Reduced capability devices
All these use-cases are designed based on a common air interface and similar protocol
stacks. The requirements for these applications are satisfied through
proprietary implementation and algorithms. Foe example, the IIoT devices
doesn’t require high data rate, have a low battery (power) and very often have
low mobility, hence the transmission algorithms such as scheduling, resource
allocation, precoding and beamforming and reception algorithms such as receive
combining, channel estimation and data demodulation must be designed keeping
all these requirements constraints in mind.
Gigayasa Wireless has designed simulators which supports and implements all these
use-cases to carry out research on different modules of all these applications.
Moreover, many sub-cases of these use-cases such as IIoT positioning, sidelink
positioning, device to device communication, IIoT communication, reduce
capability device communication etc.
