A user terminal, in a 3GPP network comprising a receiving section arranged to receive DL signals transmitted in an FDD cell and a TDD cell by employing carrier aggregation; and a transmission control section arranged to allocate and transmit delivery acknowledgement signals in response to the received DL signals, wherein the transmission control section is further arranged to allocate and transmit one of: channel quality information or scheduling requests in given UL subframes, wherein, when one of the FDD cell and the TDD cell is an SCell, PUCCH transmission is configured in both the FDD cell and the TDD cell and PUCCH transmission in the FDD cell and PUCCH transmission in the TDD cell are performed at a same time, the transmission control section is arranged to transmit a delivery acknowledgement signal in UL subframes in both of the FDD cell and the TDD cell, and to control transmission of channel quality information or a scheduling request having an overlapping transmission timing with the delivery acknowledgement signal, and wherein the transmission control section is arranged to multiplex and transmit the delivery acknowledgement signal, and the channel quality information or the scheduling request upon a PUCCH of each cell. a receiving section arranged to receive DL signals transmitted in an FDD cell and a TDD cell by employing carrier aggregation; and a transmission control section arranged to allocate and transmit delivery acknowledgement signals in response to the received DL signals, wherein the transmission control section is further arranged to allocate and transmit one of: channel quality information or scheduling requests in given UL subframes, wherein, when one of the FDD cell and the TDD cell is an SCell, PUCCH transmission is configured in both the FDD cell and the TDD cell and PUCCH transmission in the FDD cell and PUCCH transmission in the TDD cell are performed at a same time, the transmission control section is arranged to transmit a delivery acknowledgement signal in UL subframes in both of the FDD cell and the TDD cell, and to control transmission of channel quality information or a scheduling request having an overlapping transmission timing with the delivery acknowledgement signal, and wherein the transmission control section is arranged to multiplex and transmit the delivery acknowledgement signal, and the channel quality information or the scheduling request upon a PUCCH of each cell. channel quality information or scheduling requests in given UL subframes, wherein, when one of the FDD cell and the TDD cell is an SCell, PUCCH transmission is configured in both the FDD cell and the TDD cell and PUCCH transmission in the FDD cell and PUCCH transmission in the TDD cell are performed at a same time, the transmission control section is arranged to transmit a delivery acknowledgement signal in UL subframes in both of the FDD cell and the TDD cell, and to control transmission of channel quality information or a scheduling request having an overlapping transmission timing with the delivery acknowledgement signal, and wherein the transmission control section is arranged to multiplex and transmit the delivery acknowledgement signal, and the channel quality information or the scheduling request upon a PUCCH of each cell.
