METHOD FOR PERFORMING MEASUREMENT THROUGH ELIMINATING INTERFERENCE AND TERMINAL

摘要

The present invention provides a method for performing a measurement by a terminal in a wireless communications system having both a macro cell and a small cell. The method for performing a measurement includes the step of receiving CRS (Cellspecific Reference Signal) support information from the macro cell or the small cell which works as a serving cell. The CRS support information may contain the information of a cell sending a CRS causing interference. The method may include the step of receiving respectively a CRS from the macro and a CRS from the small cell. Here, a timing offset may be adjusted between the sub-frame receiving the CRS from the macro cell and the sub-frame receiving the CRS from the small cell.

1. A method for performing measurements by a terminal in a wireless communication system in which a macro cell and a small-scale cell coexist, the method comprising:
receiving Cell-specific Reference Signal (CRS) assistance information from any one cell that corresponds to a serving cell among the macro cell and the small-scale cell, wherein the CRS assistance information includes information on a cell that transmits a CRS that causes interference; receiving each of the CRS from the macro cell and the CRS from the small-scale cell, wherein a timing offset is adjusted between a subframe in which the CRS is received from the macro cell and a subframe in which the CRS is received from the small-scale cell; and performing a measurement for the CRS from the serving cell by performing the interference cancellation function for the remaining CRS except the CRS from the serving cell using the CRS assistance information.
