Abstract
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 that receives downlink control information (DCI) including Downlink Assignment Index (DAI) in a frequency division duplex (FDD) cell and controls, based on the DAI, transmission of a transmission acknowledgement signal for a downlink shared channel that is scheduled to the FDD cell by the DCI.
Claims5
A user terminal comprising:
- a receiving section that receives downlink control information (DCI) including Downlink Assignment Index (DAI) in a frequency division duplex (FDD) cell;
- and
- a control section that controls, based on the DAI, transmission of a transmission acknowledgement signal for a downlink shared channel that is scheduled to the FDD cell by the DCI.
A radio base station that transmits downlink control information (DCI) including Downlink Assignment Index (DAI) in a frequency division duplex (FDD) cell;
- and
- a control section that controls, based on the DAI, reception of a transmission acknowledgement signal for a downlink shared channel that is scheduled to the FDD cell by the DCI.
