    摘要： The present invention is designed so that uplink transmission is carried out adequately even when CA is executed by applying different duplex modes between multiple cells. A user terminal communicates with an FDD cell and a TDD cell by using carrier aggregation, and has a receiving section that receives DL signals transmitted from the cells, and a feedback control section that allocates and feeds back transmission acknowledgment signals in response to each DL signal in an uplink control channel of a predetermined cell, with reference to tables in which at least the states of transmission acknowledgment signals, PUCCH resources and QPSK symbol points are associated with each other, and, in this user terminal, the tables define different contents between the FDD cell and the TDD cell, and regardless of the cell where downlink control information is detected and the cell where downlink shared data is detected, the feedback control section uses the table that corresponds to the duplex mode of the predetermined cell where the transmission acknowledgment signals are transmitted.

    摘要： Even when a same C-RNTI is allocated to multiple mobile stations UE#A to UE#D in a phantom cell, a collision between the mobile stations UE#A to UE#D to which the same C-RNTI is allocated is avoided. A mobile communication method according to the present invention includes the steps of transmitting a first control signal including an identifier different from a C-RNTI to the mobile station UE#A through a PDCCH by a radio base station PhNB#10 managing a cell #10 formed by linking multiple small cells, transmitting a second control signal including the identifier to the mobile station UE through a PDCCH by a radio base station eNB#1 managing a cell #1 having a coverage area overlapping with a coverage area of the cell #10, and regarding the first control signal as valid by the mobile station UE, when it determines that the identifier included in the first control signal and the identifier included in the second control signal match each other.

    摘要： The present invention is designed to provide highly efficient small cell radio access. Local stations (20) transmit small cell-specific DISCOVERY SIGNALS, and a mobile terminal apparatus (10) receives MEASUREMENT CONFIGURATION, in which a DS reception control signal is contained, from a macro station (30). The mobile terminal apparatus (10) receives the DISCOVERY SIGNALS based on control information reported by the MEASUREMENT CONFIGURATION. The macro station (30) selects local stations whose CSI information is to be fed back, based on DISCOVERY SIGNAL MEASUREMENT reports, and reports RRC CONNECTION RECONFIGURATION, in which local station information for feeding back CSI information is contained, to the mobile terminal apparatus (10).

    摘要： The radio communication system has a user equipment, a first base station, a second base station, a serving gateway, and a switching station. The first base station has a control-plane path set to the switching station. The second base station has no control-plane path to the switching station. A path setting determiner determines whether to set a user-plane path, based on measurement information reported from the user equipment. A base station determiner determines, based on identification information obtained by the user equipment, whether a base station to which the user-plane path is to be set is the second base station, the base station corresponding to the obtained identification information.
