摘要： 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 (103) sets a search space having a plurality of allocation candidates, in both regions.

摘要： The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.

摘要： A radio communication device in which the waste of physical resources involved in the repetition transmission of a response signal can be minimized with no restriction on the scheduling of a base station imposed or with the restriction on the scheduling thereof minimized. In this device, a control unit (209) selects the ZAC sequence of the cyclic shift amount corresponding to a PUCCH number inputted from a determination section (208) from among ZAC#0 to ZAC#11 to set it to a spreading section (215) and selects the block-wise spreading code sequence corresponding to the PUCCH number inputted from the determination section (208) from BW#0 to BW#2 to set it to a spreading section (218). More specifically, the control unit (209) selects any of the resources defined by the ZAC#0 to ZAC#11 and the BW#0 to BW#2. As a result, the more the number of transmissions of the response signal, the less the number of resources the control unit (209) can select.

摘要： Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

摘要： Provided are a wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when non-contiguous bands allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance.
