Claim Text:
1. A mobile communication terminal in a mobile communication system, the mobile communication terminal comprising: a variation amount adjusting unit configured to: a distance change detecting unit configured to detect a change in a distance between the mobile communication terminal and the base station, based on uplink transmission timing information, wherein: the variation amount adjusting unit is further configured to determine an excessive transmit power control when: (i) a cumulative value of first variation amounts during a predetermined time period exceeds a threshold value, the first variation amounts each corresponding to a transmit power control (TPC) value, (ii) an uplink transmit power value exceeds a reference value for the uplink transmit power, the reference value being corresponding to a timing adjustment (TA) value; and (iii) when the detected change in the distance indicates that the distance between the mobile communication terminal and the base station is decreasing, and the variation amount adjusting unit is further configured to use the second variation amount for uplink transmit power control, when the excessive transmit power control is determined.
