METHOD FOR CONTROLLING INTER-CELL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/174312

Kind Code:

A1

Abstract:

A method for a base station to control inter-cell interference in a wireless communication system comprises: a step in which a base station receives, in a predefined physical resource region, a demodulation reference signal (DMRS) or a sounding reference symbol (SRS) from a terminal in a cell to which the base station belongs; a step of measuring interference in a resource on which the DMRS or the SRS has been transmitted, on the basis of an interference measurement method corresponding to the predefined physical resource region; and a step of determining the terminal as a victim terminal associated with the predefined physical resource region, if the intensity of the interference measured is greater than a predetermined threshold, wherein the predefined physical resource region may be a first physical resource region for an uplink data transmission in the cell to which the base station belongs, or a second physical resource region for uplink beam sweeping in the cell to which the base station belongs, the first and second physical resource regions corresponding to a physical resource region for uplink beam sweeping in a neighboring cell to which a neighboring base station belongs.
