摘要： In order to make transmission power control of a PDCCH signal in an appropriate manner in a communication system having a system band formed with a plurality of fundamental frequency blocks, the present invention provides a radio base station apparatus having: a transmitting section configured to transmit downlink control channel signals for respective fundamental frequency blocks to a mobile terminal apparatus; and a receiving section configured to receive retransmission response signals that are transmitted in a predetermined fundamental frequency block from the mobile terminal apparatus. In the transmitting section, a transmission power control section (211) is provided to control transmission power of the downlink control channel signals based on the number of transmissions N of a downlink control channel signal transmitted from the transmitting section during a predetermined time period and information about the number of transmissions of a predetermined retransmission response signal transmitted from the mobile terminal apparatus in response to each of downlink shared channel signals associated with the downlink control channel signals transmitted during the predetermined time period.

摘要： A base station of a mobile communication system includes a receiver that receives capability information including information regarding plural frequencies which are measurable by the user equipment; an identifying unit that identifies, subsequent to allocation of radio resources to the user equipment, one or more different frequencies which are measurable by the user equipment and different from a frequency of a serving cell, among the plural frequencies in the capability information; and a transmitter that transmits a different frequency measurement command signal for commanding the user equipment to measure the identified one or more different frequencies or all the different frequencies, which are measurable by the user equipment, to the user equipment. The receiver receives a report signal indicating presence or absence of coverage for each of the one or more different frequencies from the user equipment that performs the measurement in response to the different frequency measurement command signal.
