摘要： A communication method for a radio communication system employing an enhanced uplink scheme includes the steps of determining a transmission power control bit for controlling transmission power of a downlink control channel; generating an uplink control signal including the transmission power control bit; and transmitting the uplink control signal to a base station. In the determining step, whether an indicator channel indicating acknowledgement or negative acknowledgement for an uplink data channel is receivable at a quality level better than a predetermined value is evaluated, and the transmission power control bit of the indicator channel is determined based on the evaluation result.

摘要： A disclosed communication terminal includes a determination unit analyzing a received downlink control signal and determining an allowable maximum uplink transmission power level, a measurement unit performing different frequency measurement in a transmission gap period, a threshold determination unit determining whether the allowable maximum level is higher than or equal to a threshold within a predefined period before the start and/or after the end of the transmission gap period, a transmission power control unit setting an uplink transmission power level, and a transmission unit transmitting an uplink signal at the determined power level. If the allowable maximum 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 level within the predefined period before the start and/or after the end of the transmission gap period.
