Improved Performance Scheme for Joint Transmission in Downlink Coordinated Multi-Point Transmission

Authors: Hyoung-Kyu Song, Su-Hyun Jung, Young-Su Ryu, Myoung-Jin Kim


In this paper, improved performance scheme for joint transmission (JT) is proposed in downlink (DL) coordinated multi-point (CoMP) in case of the constraint transmission power. This scheme is that a serving transmission point (TP) requests the JT to an inter-TP and it selects a precoding technique according to the channel state information (CSI) from user equipment (UE). The simulation results show that the bit error rate (BER) and the throughput performances of the proposed scheme provide the high spectral efficiency and the reliable data at the cell edge.

Keywords: CoMP, joint transmission, zero-forcing, zero-forcing dirty paper coding, minimum mean square error
