WORK PACKAGE 1

Spectrum requirements and assessment The ITU-R spectrum allocations for mobile services in the 3 frequency

ranges have been investigated

Contiguous bandwidths, suitable for 5G operations, have been identified

Availability of technology components has been studied

It is an indication of the technology readiness

4 KPIs have been analysed to define the suitability of the 3 ranges

coverage, capacity, mobility and device complexity

Strand 1: Fix the system bandwidth (~500MHz) and study the impact of incrementing number of antenna elements.

Strand 2: Fix the number of antenna elements (Nant=32) across the frequency range and study the impact of incrementing the bandwidth.

Work is continuing, taking into consideration WRC’15 outcome

Measurement campaigns: over 20 measurement campaigns in more than 8 frequency bands from 6 to 100 GHz are ongoing across Europe, and will continue till the end of the project.

Scenarios: UMi street canyon, UMi open square, indoor office, indoor shopping mall, indoor airport, outdoor to indoor (O2I), metro station and stadium.

Initial channel model in line with the 3GPP-3D has been implemented supporting 10-80

GHz.

Utilizing 3D Ray-tracing on 5/18/28/38/73 GHz bands to model the channel propagation

Radio propagation is simulated and traced on 3D model environments (3D building data)

All paths are modeled by reflection, diffraction, and penetration

based on the geometrical optics (GO) and uniform theory of diffraction (UTD)

Up to 40 paths are traced (within 250 dB measurable pathloss)

Output : total power, path power, path delays, path angle information (elevation / azimuth @ TX/RX)

Multi-antenna beamforming is essential yet challenging for 5G above 6 GHz

Develop novel BF solutions meeting complexity, cost, performance and energy aspects of 5G.

The multi-node solutions need to be multi faceted.

Beyond CoMP type dynamic associations of 5G small cell base stations

Beyond MU-MIMO type dynamic associations of multiple UEs.

Multi-RAT type CoMP sets involving legacy cells (4G/3G), esp for maintaining connectivity/ signalling.

The solutions developed cover access, backhaul and front-haul scenarios.

Selected “extreme” use cases highlight different challenges for each of the areas.
