Title:
MOBILE COMMUNICATION SYSTEM, COMMUNICATION CONTROL METHOD, BASE STATION, AND USER TERMINAL
Document Type and Number:
WIPO Patent Application WO/2014/097766
Kind Code:
A1
Abstract:
Provided is a mobile communication system that comprises: a user terminal that receives a desired wave signal from a serving cell in addition to receiving an interference wave signal from an adjacent cell that is adjacent to the serving cell; and a base station that manages the serving cell. The base station generates an interference replica signal that corresponds to the interference wave signal, and comprises a control unit that superimposes the interference replica signal on the desired wave signal and a transmission unit that transmits the desired wave signal having the interference replica signal superimposed thereon to the user terminal. The control unit generates the interference replica signal so that the interference replica signal cancels the interference wave signal at the position of the user terminal. The interference replica signal functions as an interfering signal that interferes with demodulation of the desired wave signal at positions other than the position of the user terminal.
