Abstract

In a base station (100), when the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are the same, a transmission controller (102) sets a first data resource region inside a first resource region, in a resource block group (RBG), that can be used for the control channel or the data channel. When the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are different, a transmission controller (102) sets a second data resource region inside the first resource region in the RBG. The second data resource region is larger than the first data resource region.

Claims11

Dependent claims

A transmitting apparatus that maps a control signal for a receiving apparatus to a first resource region usable for both a control channel and a data channel or a second resource region usable for a control channel and transmits the mapped control signal, and maps transmission data to a data resource region and transmits the mapped transmission data to the receiving apparatus, the transmitting apparatus comprising:

a generating section that generates an allocation control signal for the data resource region;
a setting section that sets a first data resource region within the first resource region in a resource block group (RBG) composed of M resource blocks (RBs), where M is a natural number equal to or greater than two, when the number of streams used to transmit the transmission data is one and an antenna port used to transmit the transmission data is identical to the antenna port used to transmit the allocation control signal, and
that sets a second data resource region larger than the first data resource region within the first resource region in the RBG when the number of streams used to transmit the transmission data is one and the antenna port used to transmit the transmission data is different from the antenna port used to transmit the allocation control signal;
and
a mapping section that maps the transmission data to the set first data resource region or the set second data resource region, and maps the allocation control signal to a control resource region within the first resource region.

A receiving apparatus that receives a received signal including a control signal transmitted from a transmitting apparatus in a first resource region usable for both a control channel and a data channel or a second resource region usable for a control channel, and receives transmission data mapped to the first data resource region or the second data resource region and transmitted from the transmitting apparatus, the receiving apparatus comprising:

a detection section that detects an allocation control signal for the data resource region included in the received signal;
an identifying section that identifies a first data resource region within the first resource region in a resource block group (RBG) composed of M resource blocks (RBs), where M is a natural number equal to or greater than two, as a data component region to be extracted, when the number of streams used to transmit the transmission data is one and an antenna port used to transmit the transmission data is identical to the antenna port used to transmit the allocation control signal;
and
the identifying section that identifies a second data resource region larger than the first data resource region within the first resource region in the RBG as the data component region to be extracted, when the number of streams used to transmit the transmission data is one and the antenna port used to transmit the transmission data is different from the antenna port used to transmit the allocation control signal;
and
an extracting section that extracts from the received signal, a signal component within the identified data component region to be extracted.
