Summary

The project aims at providing a ubiquitous wireless solution to reach bit rates higher than 100Mbps with peak throughputs higher than 1Gbps, based on Reconfigurable OFDMA Cooperative Networks enabled by agile spectrum use (ROCKET). While increasing peak rates is a natural must-do for new standards, we believe in ROCKET that providing homogeneous high rate coverage is equally important as it guarantees a constant user experience over the whole served area and is the key enabler to a higher average spectral efficiency of the system. Those goals are inline with the IMT-Advanced requirements described in [ITU-R M1645] and match the requirements of the IEEE 802.16 Task Group m (TGm) for Advanced Air Interface. In order to guarantee a strong focus and efficiency in the project, we propose to limit the scope of our investigations to two questions which we believe will be at the centre of future IMT-advanced system design:

1) How can we increase the bandwidth and make the whole system benefit from it?

2) How can we increase system spectral efficiency and provide ubiquitous high-rate coverage?

Those questions are addressed by devising methods for improved spectrum usage, advanced multi-user cooperative transmission and ultra-efficient MAC design. Providing inputs to standardization bodies, generating IPR and conceiving architectures for some of the algorithms on a hardware platform are the ways the project plans to have actual impact.
