Integrated circuit that controls a search space setting process
First Claim
1. An integrated circuit comprising:
- reception circuitry which, in operation, receives a first downlink control channel transmitted on one or more control channel element(s) (CCE(s)) in a first search space that is comprised of a first plurality of CCEs, the first downlink control channel including resource assignment information, which indicates a resource allocated to a terminal apparatus in a component carrier n (CCn) out of one or more CC(s), and receives a second downlink control channel transmitted on one or more CCE(s) in a second search space that is comprised of a second plurality of CCE(s), the second downlink control channel including resource assignment information, which indicates a resource allocated to the terminal apparatus in a component carrier n+1 (CCn+1) out of said one or more CC(s), the first plurality of CCEs and the second plurality of CCEs are consecutive;
one or more inputs coupled to the reception circuitry, which, in operation, receive downlink control channel signals; and
transmission circuitry which, in operation, transmits an ACK/NACK signal on an uplink control channel, a resource index of the uplink control channel being associated with a CCE number of said one or more CCE(s) in the first search space.

Abstract
An integrated circuit, for example, included in a wireless communication base station, controls a process that includes mapping a first downlink control channel to control channel element(s) (CCE(s)) in a first search space comprised of a first plurality of CCEs, the first downlink control channel including resource assignment information, which indicates a resource allocated to a terminal in a component carrier n (CCn) out of one or more component carrier(s) (CC(s)), and mapping a second downlink control channel to CCE(s) in a second search space comprised of a second plurality of CCE(s), the second downlink control channel including resource assignment information, which indicates a resource allocated to the terminal in a component carrier n+1 (CCn+1) out of the CC(s), the first plurality of CCEs and the second plurality of CCEs are consecutive. The process also includes transmitting the first and the second downlink control channels to the terminal.
