Patent ID: 8515426

Claim:
A user equipment in which a handover from a macro cell base station to a small cell base station is controlled based on a result of comparison between macro cell reception quality and small cell reception quality, the macro cell reception quality being reception quality of a signal from the macro cell base station and the small cell reception quality being reception quality of a signal from the small cell base station located in a macro cell, the user equipment comprising: a reception quality measurement unit for measuring the macro cell reception quality and the small cell reception quality; an offsetting unit for offsetting the macro cell reception quality or the small cell reception quality with an offset value that makes the small cell reception quality relatively higher than the macro cell reception quality; an offset value correcting unit for correcting the offset value according to the macro cell reception quality; and a correction value receiving unit for receiving a first correction value and a second correction value set to a value larger than the first correction value from the macro cell base station, wherein the offset value correcting unit corrects the offset value with the first correction value when the macro cell reception quality is higher than a first threshold value, and corrects the offset value with the second correction value when the macro cell reception quality is lower than a second threshold value, wherein the transmission power of the small cell base station is controlled to increase when the macro cell reception quality is lower than the second threshold value, and the user equipment further comprises: a threshold value receiving unit for receiving a third threshold value from the small cell base station; and a reception quality determining unit for determining whether or not the small cell reception quality is higher than the third threshold value, wherein when it is determined that the small cell reception quality is higher than the third threshold value, the transmission power of the small cell base station is controlled to decrease.
