Objective
As the mobile Internet is becoming reality, the demand for an ubiquituos, high-bandwidth Internet access anytime, anywhere is continuously increasing. As spectrum is limited, this means that future mobile communications systems have to support significantly higher spectral efficiencies than today's systems. The main requirements towards next generation networks can be summarized as:
- High spectral efficiency
- Fairness (e.g. good performance also for cell-edge users)
- Low capital and operational cost per bit
- Low latency
At the same time, it is known that the main limitation to spectral efficiency is the interference between adjacent cells. The project EASY-C aims at overcoming exactly this problem through a change in paradigm: Interfering signals from neighboring cells are not seen as noise, but are exploited through inter-cell cooperative techniques. Within the project, the following techniques will be investigated and evaluated through simulation as well as through the testbeds in Dresden and Berlin:
- Advanced multi-antenna (MIMO) techniques
- Multi-cell joint transmission for interference mitigation
- Multi-cell joint detection for interference cancellation
- Multi-cell interference coordination
- Cooperative relaying
