Abstract
In a terminal, a control unit transmits a bundle response signal using a resource in a basic region of an uplink control channel in an uplink unit band of a unit band group when no error is detected in each of a plurality of pieces of downlink data of the unit band group, the uplink control channel in the uplink unit band being associated with a downlink control channel in a basic unit band that is a downlink unit band in which a broadcast channel signal including information relating to the uplink unit band is transmitted, and the control unit transmits the bundle response signal using a resource in an additional region of the uplink control channel when an error is detected in each of the plurality of pieces of downlink data.
Claims32
An integrated circuit to control a process, the process comprising:
- transmitting, to a terminal, control information on a control channel element (CCE), the control information including downlink assignment information that indicates respective downlink data resources assigned to one or more downlink component carrier(s) of a plurality of configured downlink component carriers, the plurality of configured downlink component carriers including at least a first downlink component carrier and a second downlink component carrier;
- transmitting, to the terminal, downlink data in the respective resources;
- and
- receiving respective response signals to the downlink data, the response signals being transmitted from the terminal,
- wherein:
- when control information on the first downlink component carrier is detected and control information on the second downlink component carrier is not detected by the terminal, a response signal is received using a first uplink control channel resource, an index of which is associated with a number of the CCE;
- and
- when control information on the second downlink component carrier is detected and control information on the first downlink component carrier is not detected by the terminal, a response signal is received using a second uplink control channel resource, an index of which is signaled to the terminal.
An integrated circuit comprising circuitry, which, in operation:
- controls transmission, to a terminal, of control information on a control channel element (CCE), the control information including downlink assignment information that indicates respective downlink data resources assigned to one or more downlink component carrier(s) of a plurality of configured downlink component carriers, the plurality of configured downlink component carriers including at least a first downlink component carrier and a second downlink component carrier;
- controls transmission, to the terminal, of downlink data in the respective resources;
- and
- controls reception of respective response signals to the downlink data, the response signals being transmitted from the terminal,
- wherein:
- when control information on the first downlink component carrier is detected and control information on the second downlink component carrier is not detected by the terminal, a response signal is received using a first uplink control channel resource, an index of which is associated with a number of the CCE;
- and
- when control information on the second downlink component carrier is detected and control information on the first downlink component carrier is not detected by the terminal, a response signal is received using a second uplink control channel resource, an index of which is signaled to the terminal.
