The support for sub millisecond extreme low latency (ELL) is an open issue for the emerging cellular Machine-Type Communication (MTC) networks, currently not supported by cellular networks. ELL is required for vehicular safety, autonomous driving applications and for other MTC that have arisen with the advent of the Internet of Things, and for new human-initiated (HI) communications, such as tactile Internet applications. This project addresses the design of the last mile of a wireless communication network capable of supporting end-to-end ELL for thousands of MTC and HI devices per access node with improved energy efficiency. A capillary network of small cells will be considered. The project will focus on the design of new physical (PHY) and medium access control (MAC) layer protocols, and of network services, to support MTC ELL communications. Several components will be integrated:- Spectral efficient PHY-layer modulation schemes (MS) with reduced out-of-band (OOB) spectral leakage, that do not require synchronous reception and minimize MTC initial transmission delay; - Asynchronous Multiple MultiPacket Reception (MPR) techniques, to maximize the capacity to handle load peaks, reducing the initial contention delay;- Advanced sensing techniques that estimate the number of devices transmitting concurrently;- Interference management (IM) through a radio resource management (RRM) service, which combines base station (BS) and device sensing;- Coarse-synchronized MAC protocols designed to support a fast initial transmission and optimized subsequent ones, using the RRM service’s information;- Power saving (PS) mechanisms compatible with ELL;- Cloud-based radio access network (C-RAN), to support a flexible on-demand implementation of spatial based MPR techniques, capable of satisfying the strict ELL requirements.The research team is organized into a PHY layer group and a MAC (and upper) layers group, which in the past collaborated in the design of cross-layer projects.

This project aims to integrate MPR, IC, PHY-cooperation, CRD and AM technologies in a single architecture particularly tailored for ILWNs, which is itself a challenging task due to the lack of a central coordinator and the spatial distribution of the nodes. The maingoal of the project is to investigate if the theoretical capacity of ILWNs can be achieved by practicalcommunication systems, or at least evaluate how far an optimized solution, such as the one proposed in this project, is from thetheoretical capacity bound. The communication systems’ architecture proposed for each node will be based on a cross-layeringdesign between the physical and the MAC sub-layer.

The project will take LTE-Advanced as a reference and will explore possible enhancements to the support of femtocells. It will use mechanisms to reduce the interference-limited transmission with full frequency reuse. These include CQI, QoS- and interference- aware scheduling and RRM with user-grouping, coordinated RRM, exploiting the spatial degrees of freedoms from multi-antenna systems and OFDMA through MIMO and beam forming techniques, active interference management and CoMP transmission, as well as carrier aggregation for multi-band transmission.New technologies like aggregate carriers and cooperative multi antennas antenna systems as part of LTE-Advanced systems will be evaluated with respect to their ability to enhance the performance of networked femtocells based on LTE-A. The availability of Positioning information, can help provide the network with information on the terminal positions and, with this, to adapt the transmission scheme to the terminal avoiding worst channel conditions.At the network layer, considerable research and development has been recently focused on the use of small cellular base stations. However, those cells have only been considered as mere extensions to cellular networks, allowing the enlargement of service coverage. The use of these small cells, mostly deployed by consumers, has not yet been fully explored. There are many services and protocols in the network that could benefit on the scattering of this kind of cell deployment. This project will exploit the opportunities that small cells will bring to improvement on the network architecture. The aim is to a achieve a much richer small cell, that will provide better support for several services and protocols that could take advantage on a distributed architecture and/or context ware and localized information.Femtocells can have many benefits for both operators and users. From an operational or deployment perspective however their integration into the network is quite hard. From the ...

The main objective of SAAS is to develop an UAV remote control system that is mostly independent of a specific vehicle model or design and that makes use of the available terrestrial wireless networks. The individual challenges and objectives to be addressed are:• Real-Time Video Transmission and Control using Terrestrial Wireless Networks: Investigate the possibility of transmitting real time video and control commands with adequate quality for a pilot to control and make decisions on the vehicle course using the available radio networks (GSM, UMTS, HSDPA, Wi-Fi, LTE).• Semi-autonomous Flight Control: Develop autonomous control capabilities for the aircraft to perform its self-rescue in the case of loss of radio connection and that can also allow a reduced piloting workload.• Remote Visualization and Control Application: Implement an application for tablet PCs that enables the visualization of the video captured by the aircraft cameras together with other telemetry information and allows the pilot to command the aircraft (either using the touchscreen, the accelerometers or an additional attached joystick).• Prototype Implementation and Flight Tests: Implement a prototype using a small rotary-wing aircraft (possibly a tricopter/quadcopter) and evaluate the performance in terms of video reception, control, and autonomy capability.

The main goal of COILS is the design and evaluation of efficient methods for the provision of broadband services and applications based on MBMS to groups of mobile users located mainly in Personal Cells. The use of MBMS over Personal Cells will support the efficient use of radio and network resources, while also providing rich context information to applications and services. Merging these two frameworks promises enhanced multimedia application provisioning, benefiting end users and operators alike. The technologies investigated during the course of the project will generate considerable novel intellectual property that will become the property of IT.

New RAN technologies and IMS to support future MBMS based on Long term Evolution of 3GPP

Present several enhancemnt techniques suitable for multicast and briadcast to increase the capacity of UMTS networks in order to enable multimedia broadcast/multicast services (MBMS). The scenario chosen to test by simulation the enhancement techniques suitable for multicast and broadcast is a part of Lisbon City.

B-BONE main objective is to further enhance UMTS capacity, transmission rates, RAN and Core network functionalities, considering both FDD and TDD modes, so as to accommodate digital broadcasting/multicasting (multimedia) type services.

SEACORN provides a fundamental contribution to the evaluation and development of Enhanced UMTS networks. It covers several aspects starting from the definition and characterisation of services and user profiles, including the modelling of the user's behaviour with respect to mobility and multimedia activity, and finally considering the optimisation of the networks from both points of views: the operator's and manufacturer's view of limiting the infrastructure and maintenance costs and the user's view of being provided with high quality services
