Integrated circuit that controls a search space setting process
First Claim
1. An integrated circuit, comprising:
- control circuitry which, in operation, controls mapping of a first downlink control channel to 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 in a component carrier n (CCn) out of one or more component carrier(s) (CC(s)), and mapping of a second downlink control channel to 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 in a component carrier n+1 (CCn+1) out of said CC(s), the first plurality of CCEs and the second plurality of CCEs are consecutive; and
transmission circuitry which, in operation, controls transmission, to the terminal, of the first downlink control channel and the second downlink control channel.

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 (CC+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.

12. An integrated circuit comprising:
-
circuitry, which, in operation; maps a first downlink control channel to 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 in a component carrier n (CCn) out of one or more component carrier(s) (CC(s)), and maps a second downlink control channel to 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 in a component carrier n+1 (CCn+1) out of said CC(s), the first plurality of CCEs and the second plurality of CCEs are consecutive; and controls transmission, to the terminal, of the first downlink control channel and the second downlink control channel; and at least one input coupled to the circuitry, wherein the at least one input, in operation, inputs data. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
