Realising TERRANOVA’s ambitious and long-term vision requires a concrete scientific methodology combined with a well-established work plan. In what follows, we describe how and by which means we will achieve the project objectives and consolidate them towards the envisaged system concept. TERRANOVA’s work plan is organised around five key interacting Work Packages (WPs), complemented by the necessary project management and dissemination, exploitation and communication activities performed under the first (WP1) and the last (WP7) Work Package, respectively.

WP2 – System Requirements, Concept and Architecture: Led by Altice Labs, WP2 will focus on the system requirements, architecture and evaluation. WP2 will determine the system requirements a THz wireless access based system, integrated with the optical part of the network, has to fulfil. A system architecture for satisfying these requirements will be devised. The system requirements and architectural model will be determined at the beginning of the project. At a later stage in the project, WP2 will gather and compile the simulation results that have been obtained in all WPs (especially WP3 and WP4) for evaluating the system performance and benchmarking the demonstration and validation performance in WP6. Furthermore, complementary system simulations will be conducted to quantify the complete system level performance.

WP3 – THz Wireless Link Design: Led by University of Oulu, WP3 will focus on channel modelling, device tracking, and information theoretic aspects in the THz band. In particular, WP3 will design channel models for THz wireless communication taking into account all the major propagation phenomena leading to an accurate model for THz propagation. WP3 will also explore and design device tracking algorithms, able to cope with micro- and macro-mobility, which allow THz wireless links to be a practical part of an access system. Requirements for hardware to support device tracking for THz links will also be identified. Based on the developed channel models, WP3 will also include information theoretic analysis for extreme wideband systems with low signal-to-noise ratios. Wireless THz networks are modelled based on the novel information theoretic concepts. Both link-level and network-level information theoretic results will be developed and used in designing novel and efficient THz link technologies, coding and modulation as well as networking.

WP4 – THz Wireless Access and Resource Management: Led by the University of Piraeus Research Centre, WP4 will focus on THz wireless access and resource management concepts with a view to optimise the end-to-end TERRANOVA system. In particular, WP4 will explore and design new multi-user/device medium access protocols for THz communication systems able to cope with distance-dependent bandwidth, new channel and interference models and pencil-beam antenna concepts, by capitalising on extreme densification and hybrid/flexible deterministic/random access principles. Thus, the medium access of THz wireless systems will be designed from scratch coordinated by a “meta-MAC” protocol framework. WP4 will also build on top of a sub-THz/THz communication network, a system of distributed replicated caches in the small cell access points that allows for decreased congestion of the backhaul network and ensures a fast and distributed delivery of content. Finally, WP4 will exploit outputs of WP3 regarding the channel and propagation characterisation, the pencil beam-forming and the new THz network information theory along with the other peculiarities of THz communication and introduce a highly adaptable framework for optimal THz resource management. This framework will leverage concepts from advanced optimisation theory aiming at the overall end-to-end performance improvement of both backhaul and access network.

WP5 – THz System Technology: Led by Fraunhofer Gesellschaft IAFWP5 will focus on the development of key technology for the baseband unit PHY, the HF-frontend and the antenna to realise a THz wireless system with Terabit access rates. The co-design of signals/codes and hardware as well as the co-design of the optical and THz wireless part of the system is one of the key targets in WP5. The results of WP3 will define the requirements and overall system architecture for the work in WP5. The results from WP5 will be used in WP6, to implement the THz demonstrators. As an intermediate step WP5 will first provide hardware and software code for tests using off-line processing. At the end of the work package WP5 will provide the final hardware and software for implementation in the real-time THZ demonstration setups.

WP6 – THz Demonstrator Implementation and Validation: Led by Fraunhofer Gesellschaft HHI, in WP6 the technologies, concepts and solutions developed in TERRANOVA will be tested in two demonstration setups, the THz beamforming Demonstrator and the THz High-capacity Demonstrator. Both Demonstrators are first implemented using the results from WP3, 4 and 5. The THz beamforming Demonstrator will focus on the validation of the novel beamforming concept for THz carrier frequencies with an antenna array and demonstrate in a proof-of-concept experiment pencil-beamforming and device tracking. The THz High-capacity Demonstrator will focus on the validation of a high-capacity wireless link in conjunction with an optical connection between the baseband unit and the HF-frontend. This demonstrator will employ baseband algorithms for waveform generation, code generation and impairment mitigation designed for the combined optical-wireless link. For both demonstrators an implementation and test with off-line signal processing will be done as an intermediate step.

WP7 – Dissemination, Standardization and Exploitation: Led by JCP-Connect, the primary goal of this workpackage is the dissemination and standardization of the project results and methods as well as the investigation of business perspectives of the proposed solution. Both, internal collaboration (i.e., visiting researchers, joint exploitation) and external collaboration (i.e., other European projects, standardization bodies) are fundamental goals of this WP. Due to the nature of the domain, the Consortium will distribute TERRANOVA results in academia, industry and potential consumers.
