Abstract:
1. A communication terminal in an Enhanced Uplink based radio communication system, comprising: a determination unit configured to analyze a received downlink control signal and determine an allowable maximum uplink transmission power level; a measurement unit configured to perform different frequency measurement in a transmission gap period; a threshold determination unit configured to determine whether the allowable maximum uplink transmission power level is higher than or equal to a threshold within a predefined period before a start of the transmission gap period and/or after an end of the transmission gap period; a transmission power control unit configured to set an uplink transmission power level; and a transmission unit configured to transmit an uplink signal at the uplink transmission power level determined by the uplink transmission power control unit, wherein if the allowable maximum uplink transmission power level is higher than or equal to the threshold, the transmission power control unit sets the uplink transmission power level to or below a predefined level lower than the allowable maximum uplink transmission power level within the predefined period before the start of the transmission gap period and/or after the end of the transmission gap period.
