    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： In a mobile communication method according to the present invention, a mobile station (UE) transmits uplink data to a radio base station by using an uplink radio resource assigned to the mobile station by predetermined scheduling information, in a predetermined cycle. The method includes the steps: (A) notifying, to the mobile station (UE), the predetermined cycle and information on the uplink radio resource; (B) notifying, to the mobile station (UE), the predetermined scheduling information; and (C) transmitting uplink data in the predetermined cycle by using the uplink radio resource assigned by the predetermined scheduling information, the transmission starting at a certain point determined on the basis of the received predetermined scheduling information. In the step (C), the predetermined scheduling information is discarded, when the information on the uplink radio resource and information notified by the predetermined scheduling information are inconsistent with each other.
