Abstract
Coordinated Multi-Point Transmission (CoMP) was presented in LTE-Advanced standard to enhance the LTE performance and reduce the effect of intercell interference. In the downlink, there are two CoMP techniques used; one of these techniques is the Joint Processing (JP) technique. In this paper, a modified-JP technique is proposed. In the conventional JP, the second best base station (BS) is used to enhance the quality of the user signal while in the modified-JP, the second best BS is used so that the users are prevented from service blocking. Extensive simulations are conducted to illustrate the benefits achieved by applying the modified-JP techniques compared to the conventional JP one.
