Title:
BASE STATION, USER EQUIPMENT, INTERFERENCE REDUCTION CONTROL INFORMATION NOTIFICATION METHOD, AND INTERFERENCE REDUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/108145
Kind Code:
A1
Abstract:
A base station communicates with user equipment in a radio communication system in which carrier aggregation is performed, and is provided with: a reception unit which receives control information that is used in the user equipment in order to reduce an interference signal from an interference base station with respect to some component carrier used by the user equipment from the interference base station; a determination unit which determines whether or not a serving cell corresponding to the component carrier and an interference cell formed by the interference base station satisfy a predetermined condition; and a transmission unit which, when the determination unit has determined that the serving cell and the interference cell satisfy the predetermined condition, transmits the control information to the user equipment.
