Transmit mode selection schemes for distributed coordinated transmission of data traffic

Coordinated Multi-Point transmission schemes have a large potential to increase spectral efficiency in cellular networks. While the physical layer aspects of coordinated transmission received a lot of attention, its integration into higher layers yet remains to be investigated. In this work, we analyze the transmit mode selection for coordinated and uncoordinated transmission of data traffic. We propose two transmit mode selection schemes to decide whether to use coordinated transmission for an object or not. One scheme is based on object size, the other one is based on queue state. We derive the optimal parameter settings for our selective coordination schemes and show how they improve system performance.
