Coordinated Multi-Point transmission and reception (CoMP) is introduced in LTE-A to mitigate co-channel interference and improve the cell-edge user experience. In this paper, the authors propose a joint transmission scheme for LTE-CoMP and they enhance the performance of CoMP with two techniques: 1- dynamic MIMO cell selection and 2- closed loop MIMO with global precoding matrix selection. A cell-edge user selects the base stations that jointly transmit the desired signal from the available ones. The user also selects the closed loop precoding matrices for MIMO in a joint fashion to fit the independent MIMO channels from two base stations (eNBs).
