Abstract
The present invention provides an apparatus for suppressing interference in a coordinated multi-point CoMP transmission system, comprising: frame configuration conflicting detection unit configured to detect conflicting frame configurations; frame configuration conflicting notification unit configured to give a notification of conflicting frame configurations; and interference suppression unit configured to suppress interference between a first CoMP cluster and a second CoMP cluster that are adjacent in the CoMP transmission system when detecting conflicting frame configurations. The present invention further provides a method of suppressing interference in a coordinated multi-point CoMP transmission system. The present invention provides a novel solution that may suppress inter-cell UL/DL ICI by adopting coordinated beamforming (CBF) and coordinated scheduling (CS) in a TDD CoMP system, while maintaining sound implementation of CoMP and flexibility of frame configuration in the TDD system.
