Distributed Coordination Area Formation in Coordinated Multi-Point Transmission.

We present a distributed Coordination Area (CA) formation method for defining cooperating cells for Coordinated Multi-Point (CoMP) transmissions. We divide the available system resources into multiple resource shifts and assume independent CA realizations on different resource shifts. The multi-shift CA formation method is self-organized based on the interference situations and the traffic profile of users. The assumptions are generic for direct application to realistic networks. According to our results, the proposed multi-shift CA formation method can effectively produce multiple CAs on all resource shifts to benefit CoMP transmission.
