Title:

In a radio communications system, they are a cell interference reducing method and a device.

Document Type and Number:

Japanese Patent JP6158383

Kind Code:

B2

Abstract:

A method of a first cell for supporting a downlink channel demodulation at a user equipment, includes receiving, from a second cell, Multicast/Broadcast over Single Frequency Network (MBSFN) subframe configuration information for the second cell; and transmitting, by the first cell to the user equipment via a higher layer signaling, information on a Cell-specific Reference Signal (CRS) of the second cell including the MBSFN subframe configuration information of the second cell, wherein the information on the CRS of the second cell is used by the user equipment to mitigate the inter-cell interference from the CRS of the second cell.
