摘要：In order to achieve improved cell edge throughput in LTE-Advanced, CoMP technology is introduced to support high data rates over wider bandwidths. Coordination of control of data and channel interference is important to maintain the uplink and downlink coverage to enhance channel performance. CoMP is a new class of transmission scheme for the interference reduction and can have significant effect in terms of improving cell edge user throughput, coverage in the 4G mobile networks. This proposed article presents a coordination technique among multiple cell sites of improving the cell edge user throughput and compares different CoMP joint processing schemes. In this paper author presents a CoMP scheme where Joint Transmission is applied in the downlink of a LTE heterogeneous network structure for the purpose of interference cancellation. The technical challenges for both uplink and downlink are also addressed. Simulation results indicate that the proposed method gives an effective control of ICI and improves cell edge user throughput.
