Title:
USER DEVICE, BASE STATION, INTERFERENCE REDUCTION METHOD, AND INTERFERENCE REDUCTION CONTROL INFORMATION NOTIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/119087
Kind Code:
A1
Abstract:
A user device in a wireless communication system that includes multiple base stations, wherein the user device has a reception means that receives control information from a connecting base station, said control information being used for reducing a control channel signal from an interfering base station which interferes with the user device, and an interference reduction means that reduces the interfering control channel signal by using the control information and obtains a desired signal from the connecting base station.
