Abstract :
In the context of Long Term Evolution (LTE)-Advanced, the transmission points responsible for Coordinated Multi-Point (CoMP) transmission can be arranged in a distributed way and each one can be equipped with multiple antennas. In such scenario, efficient Radio Resource Allocation (RRA) strategies are required to exploit the available spatial degrees of freedom, coordinate the resources usage and manage the interference. This work provides system-level analyses for several RRA strategies in multi-antenna CoMP systems. The results show significant benefits in terms of system spectral efficiency for different spatial transmission strategies, including the combination of spatial multiplexing and spatial diversity.
