Abstract

Disclosed is a transmission apparatus capable of properly performing cross carrier scheduling in ePDCCHs. In this apparatus, when communication is performed using a plurality of component carriers (CCs), configuration section 102 configures a first search space as a candidate to which control information for a first CC is assigned and a second search space as a candidate to which control information for a second CC other than the first CC among the plurality of CCs is assigned, within a same allocation unit group among a plurality of allocation unit groups included in a data-assignable region within the first CC, and transmission section 106 transmits control information mapped to the first search space and control information mapped to the second search space.

Dependent claims

A communication apparatus comprising:

a configurer that configures a first search space and a second search space within one physical resource block set (PRB set) among a plurality of PRB sets included in a data region of a first component carrier, wherein the second search space is configured using a Carrier Indicator Field value (CIF value) that is set for a second component carrier, the first search space includes one or more mapping candidates for mapping a first downlink control information for the first component carrier, and the second search space includes one or more mapping candidates for mapping a second downlink control information for the second component carrier;
and
a transmitter that transmits the first downlink control information using the first search space and to transmit the second downlink control information using the second search space.

A communication method comprising:

configuring a first search space and a second search space within one physical resource block set (PRB set) among a plurality of PRB sets included in a data region of a first component carrier, wherein the second search space is configured using a Carrier Indicator Field value (CIF value) that is set for a second component carrier, the first search space includes one or more mapping candidates for mapping a first downlink control information for the first component carrier, and the second search space includes one or more mapping candidates for mapping a second downlink control information for the second component carrier;
and
transmitting the first downlink control information using the first search space and transmitting the second downlink control information using the second search space.
