Integration experiments of the Aerial LTE Platform

During this spring, the team from THALES and HELIKITES together with the suppport of BAPCO conducted initial integration tests of the ABSOLUTE LTE sub-systems on board the Aerial Helikite platform. The experiments took place in the UK at the HELIKITES premises. a few pictures of the integration tests are shown below.

The integration trials of the overall ABSOLUTE system in preparation for the final ABSOLUTE public demonstration event took place at the Mattsies airport premises close to Munich, during early July. The details of the trials will be posted soon. Also coming up shortly is the details of the final ABSOLUTE demo event.

Article accepted at IEEE Transactions on Mobile Computing

An article from ABSOLUTE project partner University of York was recently accepted for publication at the IEEE Transactions on Mobile Computing. The article title is "Distributed Heuristically Accelerated Q-learning for Robust Cognitive Spectrum Management in LTE Cellular Systems". The work presented an algorithm for Dynamic Spectrum Access (DSA) in LTE cellular systems - termed as distributed inter-cell interference coordination (ICIC) accelerated Q-learing (DIAQ), which combines distributed reinforcement learning (RL) and standardized ICIC signalling in the LTE downlink, using the framework of heuristically accelerated RL (HARL). Congratulation Neil Morozs and David Grace for the paper acceptance.

ABSOLUTE EAB BULLETIN #5

Here is the fifth EAB bulletin from ABSOLUTE, keeping you up to date on the project’s progress.

Having succeeded Jim Strother in late September 2013, I have spent the intervening period getting to grips with the ambition, intent and challenges that Project ABSOLUTE presents. The EU Project Officer convened a Technical Review of ABSOLUTE in Brussels on 9 December 2013 (more later) and preparations for the next ABSOLUTE quarterly project meeting (#5) in Paris between 5th and 7th February 2014 are underway.

As reported in Bulletin #4, the Project ABSOLUTE User Requirements (Deliverable D2.2.2) was delivered at the end of September 2013. The User Requirements set some challenging technological targets for the ABSOLUTE system in terms of reach, interoperability, capacity and connectivity. Separately, sub-system requirements have been collated by the developers of the sub-system components. The sub-system requirements considered together, collectively make-up the ABSOLUTE System Requirements. The ABSOLUTE programme provided the opportunity for the sub-system developers, having considered the user requirements, to seek further clarification and to address any issues of ambiguity back to the users in the form of a ‘corrective questionnaire’. The System Requirements have been mapped to the User Requirements. This has enabled a determination of the functionality that will be present in the system at the demonstration (September 2015) and in the fully developed capability. In undertaking the mapping process, a small number of questions have been compiled into a ‘Corrective Questionnaire to the User Representatives (Deliverable D2.4.1). This was sent to EAB members on 3 January 2014. It is testament to the efforts of the user community and the well structured requirements generation process overseen by my predecessor that so few questions have been generated by the sub-system developers. The return date for responses is 28 February 2014 and the results will be published in the next bulletin.

The project annual review took place with the European Commission Review Officer (Mr Jorge Carvalho) on 9th December in Brussels. All work package leaders were present with the co-ordinator (Isabelle) and myself. The review focussed on first year achievements; the research into current state of the art technologies, the considerable effort invested with the user to define the user requirements, the definition of technical specifications for the main ABSOLUTE components (and overall architecture) and finally, the commencement of the study of algorithms to support cognitive dynamic spectrum management. It was also noted that the project had started to contribute to the state-of-the-art, as proven by the publications in journals and participation in relevant conferences. The project was assessed as ‘Good’, having achieved most of its objectives and technical goals for the period with relatively minor deviations. Notwithstanding, the Review Board sought further information and clarification as to which of the design work in WP2 (User Requirements), WP3 (Cognitive Dynamic Spectrum Management) and WP4 (Opportunistic Communications and Networking Solutions) will be implemented in the demonstrator and have requested a further intermediate technical review in June 2014.

The next project meeting takes place in Paris between 5-7th February 2014. The length of the meeting has been extended to enable time to be focussed on addressing the specific issues raised at the project review. I will be able to update the meeting in respect to the responses received to the ‘Correct Questionnaire (D.2.4.1).

Don’t forget the public project web-site at www.absolute-project.eu , and the blog which Jim had been updating on user related matters from time to time. My ABSOLUTE New Year’s Resolution is to provide regular updates on the web-site viz-a-viz progress. At the recent review, the Reviewers enquired as to why the EAB Bulletins were not on the public side of the web-site. Noting their contentment for wider promulgation of ABSOLUTE related information, it was agreed that all previous and future EAB bulletins would be placed in the public area. I will encourage the partners to report progress in their respective areas (via posts) as the research and development phase progresses. There will continue to be within the partners’ section, a special area for EAB members, where we will upload information of interest to you but not always for public view.

If you have not yet registered please, please contact me via e-mail ( This email address is being protected from spambots. You need JavaScript enabled to view it. ) and I will forward to you the necessary details.

New EAB liaison

This is to confirm that I have now left British APCO although I will attend the project meeting next week to present the User Requirements deliverable. Gary Hughes, an ex-Royal Navy officer with extensive communications experience, will continue B-APCO's involvement in ABSOLUTE and will no doubt communicate with EAB members and our other user helpers soon.

Best wishes and thanks to those who have assisted us to date.
