A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.

Communication apparatus and communication method for receiving control information over a search space

Disclosed is a wireless communication base station device capable of reducing the power consumption of a terminal when broadband transmission is performed with only an uplink. With this device, a setting unit sets mutually different terminal IDs per a plurality of uplink unit bands for a terminal that communicates using a plurality of uplink unit bands and prescribed downlink unit bands which are fewer in number than the uplink unit bands; a control unit that respectively allocates resource allocation information per a plurality of uplink unit bands to a PDCCH arranged in a prescribed downlink unit band; and a PDCCH creation unit that creates a PDCCH signal by respectively masking the resource allocation information per a plurality of uplink unit bands with the terminal ID that has been set per a plurality of uplink unit bands.

Communication device and communication method

Wireless communication base station device, wireless communication terminal, and control information creation method

A base station () transmits a DL grant for a terminal () by mapping it to an R-PDCCH region, thus transmitting a series of data groups to the terminal () by the SPS method. A transmission control unit () sets in the R-PDCCH region a control resource region which maps a data resource and the DL grant in a resource block group common in frames to be transmitted by the SPS method. A resource region which was defined as a control resource region in a first frame to be transmitted among a plurality of frames to be transmitted is defined as a data resource in a second or subsequent frame to be transmitted.

Transmission device, receiving device, transmission method and receiving method

A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit () sets a search space having a plurality of allocation candidates, in both regions. An allocation unit () allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.
