Motivations

Huge social impacts:

3.9 billion people are unconnected around the world [1].

Improve quality of life though information and education.

Economic impacts:

New subscribers in remote areas

Better connectivity and safety

Road coverage, MTC support, Environment monitoring

Coverage needs to be large

Sparse population: #subscribers/km2

Channels with large delay profile

Link budget is very challenging

Cost reduction is mandatory

Incoming in rural/remote areas

Cost of the infrastructure deployment and maintenance

Cost of the backhaul

Cost with spectrum license

Main challenges for Remote Areas

Requirements and challenges

• Large Coverage

Low population density regions demands for large

cells

5G-RANGE target: 50 km

• Broadband connection

Reliable and high quality broadband connection

5G-RANGE target: 100 Mbps @ cell edge

• Mobility

Support for drones, cars and trains

5G-Range target: 120km/h

6September 28th 2018

• Exploit TV White Spaces and the good propagation

properties of UHF channels

• Cognitive radio approach to use vacant TV channels as

secondary user

• Employ spectrum sensing and database to avoid

interfering with incumbents

• Waveforms with good spectrum localization and high

spectrum efficiency in doubly dispersive channels

• Licensed narrow control channel for network coordination

Principles and Strategies

7September 28th 2018

• Waveform (PHY)

Flexibility to cover all 5G Scenarios

Low out-of-band emission and high spectrum efficiency

Robustness against time and frequency dispersive channels

Integration with advanced communication techniques

• Cognitive radio & MAC layer

Spectrum sensing

Dynamic spectrum allocation

Fragmented carrier aggregation

Robustness against dispersive channels

Range enhancement
