摘要：

In this paper, we present two novel Resource Allocation (RA) strategies based on the Signal-to-Leakage-plus-Noise-Ratio (SLNR) for the downlink (DL) of Coordinated Multi Point (CoMP) transmission in LTE-Advanced (LTE-A) system. The proposed RA strategies select the UEs that can efficiently share the same Resource Block (RB) without degrading the overall throughput by using the SLNR metric. In addition, we compare the proposed strategies to the RA based on the more common Signal-to-Interference-plus-Noise-Ratio (SINR) strategy. The SLNR-based RA is shown to provide significant gains in the overall system throughout that reach up to 80% and is shown to have even less complexity than the typical SINR-based RA, which makes it a very attractive choice for the implementation of CoMP in practical cellular systems.
