Commissariat a l'Energie atomique et aux Energies Alternatives (CEA)


Brief description of the organisation

With a staff of approx. 2000 people, the Technological Research Division (TRD) of CEA is one of the major applied research laboratories in Europe. About 85% of its activity are applied research with external partners. One of its main vocations is to help companies to increase their competitiveness through innovation and research-to-industry technology transfer. CEA is actively engaged in research work, from conceptual design to pre-industrial prototypes. Within TRD of CEA, the Communicating Systems Laboratory (LSC) researches into and develops innovative wireless networking technologies, for multimedia and machine-2-machine communications. The laboratory has a deep expertise and experience in radio technologies for wireless cellular systems and in IP-based architectures & protocols, as well as in the validation and evaluation of those technologies through simulation or software prototyping. CEA has a solid track record of successful collaborative European research projects, in particular related to wireless communication.


Main tasks attributed in the project

CEA will mainly contribute to WP3, WP4 and WP5. In WP3 CEA will work on multipoint-to-multipoint cooperative communications, transmit/receive constrained communications, device to device communications, and collaborative sensing and distributed RRM. In WP4, CEA will contribute to the HeNBs cluster management task. In WP5 CEA will contribute on the interface with the cloud in system-level aspects task.


Previous experience relevant to those tasks

In the field of wireless systems, CEA has a 15 years experience, with both theoretical (modulation, coding, DSSS, TDMA, asynchronous and synchronous CDMA, joint detection for UMTS FDD, MC-CDMA, UWB, etc.) and practicalknow-how (channel characterization, implementation and evaluation of various radio systems, ASIC and SOC design,etc.). Few years ago, the CEA (LSC) has integrated a core group of highly experienced people coming from MotorolaLabs Paris, with a great expertise in next generations wireless systems such as WiMAX, LTE-A or 802.11vht and theirintegration at the IP level. CEA staff has been involved in many EU projects, such as SENSEI, Fireworks, Rocket, FUTON, UNITE, CODIV, WINNER/WINNER+ and EARTH addressing evolutions of radio technologies for next generation wireless systems. In particular, CEA has been involved in the FREEDOM project focusing on femtocell-based networks, and actively contributing on technical topics like interference management, multi-antenna cooperation schemes (e.g. macro/femto), and radio resource management, which are very relevant to the present project proposal. Since several years, CEA is working on optimization in wireless communication devices and networks which produced a significant track record in patents and top-level conferences.
