In another embodiment, the transmission control unit 230 may indicate the adjacent base station 200B to refrain from transmitting an interference beam of the adjacent base station 200B indicated in the interference information at an indicated timing or period. Upon receiving the indication, the transmission control unit 230 in the adjacent base station 200B stops transmitting an interference beam, where interference has been detected in the user equipment 100, in the timing or period indicated by the camped base station 200A. This timing may be a timing for enabling the user equipment 100 to receive the transmitted signals reliably such as a retransmission timing for retransmission from the camped base station 200A to the user equipment 100. Since it can be estimated that the retransmission is required due to an interference beam from the adjacent base station 200B, it is necessary to stop transmitting the interference beam from the adjacent base station 200B at the retransmission timing. Also, the period may be some period such as a period where the user equipment 100 remains at the current position or a permanent period.

Next, an interference information indication operation in the user equipment according to one embodiment of the present invention is described with reference to FIG. 7. FIG. 7 is a flowchart for illustrating an interference information indication operation in the user equipment according to one embodiment of the present invention.
