USER TERMINAL, RADIO BASE STATION AND RADIO COMMUNICATION METHOD
First Claim
1. A user terminal that can communicate by using six or more component carriers, the user terminal comprising:
- a receiving section that receives downlink control information including a carrier indicator field (CIF); and
a control section that controls a receiving process of a downlink shared channel and/or a transmission process of an uplink shared channel in a predetermined component carrier based on the CIF, wherein;
the receiving section receives downlink control information including the same CIF value from different component carriers; and
the control section determines the predetermined component carrier, considering an offset that is configured to a CIF value of each component carrier that transmits downlink control information including the CIF.

Abstract
The present invention is designed so that cross-carrier scheduling is carried out adequately even when the number of component carriers that can be configured in a user terminal is expanded compared to that of existing systems. A user terminal can communicate by using six or more component carriers, and has a receiving section that receives downlink control information including a carrier indicator field (CIF); and a control section that controls a receiving process of a downlink shared channel and/or a transmission process of an uplink shared channel in a predetermined component carrier based on the CIF, and the receiving section receives downlink control information including the same CIF value from different component carriers; and the control section determines the predetermined component carrier, considering an offset that is configured to a CIF value of each component carrier that transmits downlink control information including the CIF.

6. A user terminal that can communicate by using six or more component carriers, the user terminal comprising:
-
a receiving section that receives downlink control information including a carrier indicator field (CIF); and a control section that controls a receiving process of a downlink shared channel and/or a transmission process of an uplink shared channel in a predetermined component carrier based on the CIF, wherein; the receiving section receives downlink control information including the same CIF value from different component carriers; and the control section determines the predetermined component carrier based on a table that defines information about a component carrier corresponding to a CIF of each component carrier that transmits downlink control information including the CIF. - View Dependent Claims (7)

9. A radio communication method in a user terminal that can communicate by using six or more component carriers, the radio communication method comprising the steps of:
-
receiving downlink control information including a carrier indicator field (CIF); and controlling a receiving process of a downlink shared channel and/or a transmission process of an uplink shared channel in a predetermined component carrier based on the CIF, wherein; in the receiving step, downlink control information including the same CIF value is received from different component carriers; and in the controlling step, the predetermined component carrier is determined, considering an offset that is configured to a CIF value of each component carrier that transmits downlink control information including the CIF.

10. A radio base station that can communicate with a user terminal that uses six or more component carriers, the radio base station comprising:
-
a control section that controls downlink shared channel and/or uplink shared channel allocation for a plurality of component carriers; and a transmission section that transmits downlink control information including a carrier indicator field (CIF), wherein the transmission section transmits, to the user terminal, information about a component carrier corresponding to a CIF of each component carrier that transmits downlink control information including the CIF.
