- W2018468199 abstract "This paper investigates leakage-based precoding schemes that support coordinated multi-point (CoMP) operation for Long-Term Evolution (LTE) systems studied in the 3rd Generation Partnership Project. CoMP operation, which improves cooperative transmission among cells and reduces or eliminates intercell interference, enables performance improvement in cell edge and average throughputs. Although leakage-based precoding has been investigated for multiuser multiple-input multiple-output (MIMO) systems, its extension to CoMP requires further analysis of the near-far effect under multicell deployment scenarios. To this end, we propose to incorporate the channel between a victim user equipment (UE) and the cell that serves the victim UE into the leakage-based precoding calculation. We investigated optimal linear scaling of the covariance matrix involving this channel. To determine the benefits of the investigated algorithm, multicell system level evaluations were carried out. This confirmed the improved performance of the system's average and cell edge throughputs." @default.
