• Multi-point transmission has not received adequate attention in the evolution of UMTS networks until multi-flow transmission is proposed in the HSPA + network recently. In the multi-flow transmission, the cross-point coordination is regarded as an important technique to enhance the system performance. In the existing research, most studies have only involved the multi-flow transmission in a non-coordinated pattern and considered it in the single-carrier HSPA + system. The major contribution of this paper is to propose a cross-point coordination scheme in the multi-carrier Multi-flow HSDPA (MF-HSDPA) network. Our scheme is able to achieve the coordination of both the aggregated scheduling and power allocation to improve the system performance in the multi-point and multi-carrier layout. Simulation results will show the advantages of the proposed scheme.
