Coordinated multipoint (CoMP) transmission/reception is a new transmission scheme in LTE-Advanced system to satisfy the system requirements and improve the cell-edge throughput. It is essential to design a series of feasible and effective signaling processes to implement and deploy CoMP in the real network and achieve the expected performance. In this contribution, we discuss some affecting factors that may lead to variability of the CoMP signaling process design, including the network structure, the scheduling strategy, and the activation and deactivation model. We also propose some common requirements that keep the generality of the CoMP signaling process design, during the sub process of activation, data transmission, and deactivation. In the end, we provide a brief summary of the contribution and an outlook of the future studies.
