mmWave Communications in the Built Environments

Periodic Reporting for period 1 - WAVECOMBE (mmWave Communications in the Built Environments)

Reporting period: 2017-10-01 to 2019-09-30

The foreseen exponential growth of mobile data traffic will not be uniform across geographical areas, but is mainly concentrated in hot spots that are usually located in the built environments (BEs) such as central business districts, stations, airports, stadiums, dense urban environments, etc. This poses considerable challenges that we believe can be solved by ultra dense deployment of millimetre-wave (mmW) small-cells (SCs) in conjunction with massive multiple-input multipleoutput (MIMO) in 5G and beyond 5G (B5G) wireless networks. However, there are a number of research challenges that need to be addressed for a successful deployment of 5G/B5G wireless networks: even if the theoretical background of massive MIMO is by now rather complete, the actual performance characterization and measurements of mmW antenna arrays has not yet been fully addressed at either the component or system level; mmW radio channel measurements have been performed but with limited time delay resolution, single antennas and over single radio links; and mmW bands have been considered for mobile communications, but the level of detail and diversity of BEs necessary for meaningful mmW SC deployment has not been fully exploited. Therefore, we propose here a research approach that combines the three disruptive key enabling technologies for 5G/B5G with the aim to answer fundamental questions that are still not well understood.
Objectives:
- Develop and test mmW MIMO and massive MIMO antennas.
- Characterize and model radio propagation channel at mmW bands for typical BEs (offices, homes, stations, airports).
- Characterize and model the effect of human body on MIMO radio propagation at mmW bands.
- Theoretically analyze and optimize massive MIMO mmW SC performance in the BEs.
- Jointly optimize the planning/deployment of massive MIMO mmW SC networks and their operating environments.
- Develop methods to retrofit existing buildings and to design new buildings for efficient high-capacity wireless communications in the BEs.
Expected Impact:
WAVECOMBE provides 396 PM of high quality interdisciplinary and cross-sector research training for a new generation of scientists, who will benefit from the entrepreneurial and creative environment created by the network, and deliver impact at a European level. It will produce a critical mass of highly-skilled professionals, who are advantaged by their international and inter-sector mobility. It will:
- Develop EU capacity and skills to advance mmW antenna design, channel modelling, understanding of fundamental limits of dense small cells, HetNet planning/optimisation tool development, IoT, VR and other high data rate applications in BEs.
- Integrate mmW antennas and systems more closely with BEs.
- Create strong interactions between wireless communications and building/BE/urban design and planning.
- Increase EU competitiveness in 5G/B5G, smart environment/building/city.
- Develop lasting academic and industry collaboration which ensures interdisciplinary and cross-sector research training programmes.
- Create new and exciting career prospects for the fellows.
"Here is a summary of the activities that have been carried out during the months 1-24.
• The kick off was in November 2017.
• An amendment was signed to change the coordinator (from USFD to UPV) and also to change the partner Chalmers University by University of Twente. It was signed in month 8.
• The Consortium Agreement was signed in October 2017 and amended in May 2018.
• The PMC organizes physical meetings and monthly project meeting.
• The web and the repository have been set up in the first year. The project is visible in the social media such as Twitter, LinkedIn, and YouTube.
• All 11 ESRs have been recruited and enrolled in a PhD programme. One representative person of the ESRs was elected to attend all the PMCs and teleconference meetings, and to be the link between ESRs and PMC.
• A Career Development Plan (CDP) was developed for each ESR, and it is reviewed every 6 months.
• Two workshops have been organized: ""Joint IRACON-WAVECOMBE Training Workshop on Radio Channel Modelling for 5G Millimetre Wave Communications in Built Environments"" and ""Joint IRACON-is3DMIMO – WAVECOMBE Joint Workshop"".
• One training event has been organized: ""1st WAVECOMBE Training School (WATS-1)"".
• Gapwaves and UT delivered the courses in the European School of Antenna in Sweden
• Eight papers have been submitted and presented in conferences.
• The consortium has organized an Special Issue in Radio Science special section “Radio Channel Modelling For 5G Millimetre Wave Communications In Built Environments”.
• The 7th Global 5G Event and the 28th EuCNC were held in Valencia, Spain, in June 2019. Two of our ESRs (Danaisy Prado and Samuel Romero) had the opportunity to participate not only as attendees but also as local organizers, which contributed to the development of their cross-curricular skills.
• The consortium participated to 20 worldwide events, both industrial fairs, some of which attract 80000 visitors, exhibitions, local and international networking events and conferences."
WaveComBE is offering the recruited researchers the opportunity to join a relevant topic of the current progress of the Wireless and Mobile Network Technologies on a wide spectrum of subjects including electromagnetics, signal processing and wireless network technology that is expected to have an intense implementation in the market by 2025: the mobile mmWave communications. This means that these ESRs, at the end of the project and of their PhDs, will have an experience and knowledge for which a high demand of professionals may be foreseen. The secondments of WaveComBE are also organised with the aim of enriching the skills and experiences of every ESR, according to their respective CDPs. In this sense, every ESR at the end of the project will have worked in at least two companies and one university research lab, combining the scientific and technical skills with practical implementation aspects. Ideally, the project outcome should be a group of excellent PhDs, with both technical and soft skills, that can lead future projects in the field of Telecommunications.
The institutions involved in WaveComBE can reinforce their research capacity with the inclusion in their research labs of these excellent students, and expect to have promising results, in the form of patents, prototypes and scientific publications, based on their work during the project.
Being the main objective of WaveComBE the training on research of the ESRs, the network as a whole intends to contribute to position Europe at front of the future radio communication technologies. In the industry aspect, the industrial partner Ranplan plays an important role in wireless knowledge dissemination and publicity of the WaveComBE project. The industrial partners attend the events or conferences to demonstrate the significant result, which is transferred from the ESR research to industrial product. It will not only help the public to understand the trend of wireless network development but also help the valuable and advanced wireless knowledge spread. Attending events and conferences also bring many new opportunities to exchange the knowledge with academical or industrial institution, potential cooperation with the partners outside the WaveComBE project. By doing this, it can further improve the novelty and influence of the project.
