    摘要： A base station includes a determination unit that determines whether user equipment performs radio communication through a booster, based on delay time of a signal transmitted to and received from the user equipment; a target SIR setting unit that sets a target SIR to be compared to a received SIR for performing transmission power control based on the received SIR of an uplink signal from the user equipment; a transmission power control signal generating unit that generates, based on the target SIR and the received SIR, a transmission power control signal to be set for controlling transmission power of the user equipment; and a transmitter that transmits the transmission power control signal to the user equipment. When determination is made that the radio communication is performed through the booster, the target SIR is set to be less than or equal to a predetermined upper limit value.

    摘要： A radio communication system includes a user device, a first base station, a second base station, a switching center, and a gateway device. In a handover operation performed in a situation in which a user-plane path has been established through the first base station, the first base station transmits, to the user device, a radio connection reconfiguration message commanding that a radio bearer be established between the second base station and the user device and receives a radio connection reconfiguration complete message transmitted from the user device. The first base station transmits, to the switching center, a path switching request message requesting that the established user-plane path be changed so as to pass through the second base station.

    摘要： The present invention is designed so that uplink transmission is carried out adequately even when CA to apply different duplex modes between multiple cells is executed. A user terminal communicates with an FDD cell and a TDD cell by employing carrier aggregation, and has a receiving section that receives DL signals transmitted from each cell, and a feedback control section that allocates delivery acknowledgement signals in response to the DL signals received, by allocating the delivery acknowledgment signals in a predetermined UL subframe, and, regardless of the cell that is configured as the primary cell, when UL subframes are configured in both the FDD cell and the TDD cell, the feedback control section feeds back the delivery acknowledgement signals by using a UL subframe of one or both of the cells, and, when a UL subframe is configured only in the FDD cell, the feedback control section feeds back the delivery acknowledgement signals by using the UL subframe of the FDD cell.

    摘要： The present invention is designed so that uplink transmission is carried out adequately even when CA to apply different duplex modes between multiple cells is executed. A user terminal communicates with an FDD cell and a TDD cell by employing carrier aggregation, and has a receiving section that receives DL signals transmitted from each cell, a transmission control section that allocates and transmits delivery acknowledgement signals in response to the received DL signals, channel quality information or scheduling requests in predetermined UL subframes, and, when a UL subframe is configured in both the FDD cell and the TDD cell, the transmission control section transmits a delivery acknowledgement signal in one UL subframe or both UL subframes, and controls whether or not to transmit channel quality information or a scheduling request having an overlapping transmission timing with the delivery acknowledgement signal.
