MOBILIA project targets ITU IMT-advanced requirements for future wireless systems, i.e.. peak data rates of 100 Mbps for mobile applications and 1 Gbps for low mobility. The IMT-advanced vision of future network as being formed of interworking access systems will also be considered. A derived target is to obtain an increased aggregate throughput/ user satisfaction vs. existing systems.

MOBILIA will address these various challenges, in the context of IEEE802.16m, 802.16j and beyond, 3GPP LTE. MOBILIA will study the following enabling technologies:

Multiple antennas (MIMO) schemes, new algorithms will be developed.

Relaying schemes: cooperative relays, can be seen as “virtual MIMO”, and may compensate spectral efficiency imbalance between cell center and edge. Several schemes will be developed and evaluated.

In both cases, realistic performances will be obtained with polarized 3D channel models derived from a ray tracing tool, diagrams of RF and antennas developed in the project (see below). Diversity, a combined effect of propagation channel and antenna diagrams, will be studied, with a focus on polarization diversity.

Cross-layer techniques for multi user MIMO and relays, assessed by system level simulations Cross-layer techniques for energy saving, aiming to increase battery life Network and functional architecture supporting the efficient and transparent cooperation between heterogeneous wireless access networks. Service framework for adaptation of services to underlying resources

Reconfigurability at baseband, RF and antennas levels, facilitating heterogeneous handovers and reducing terminal cost.
