摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2̂n×3̂m×5̂l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2̂n×3̂m×5̂l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number

摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.

摘要： There are provided a wireless communication apparatus, a wireless communication method, and a wireless communication system capable of selectively utilizing the advantages of both centralized control and distributed control while a time needed for cell searching is suppressed. FIG. 4(a) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are frequency-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a distributed control resource. FIG. 4(b) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are time-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a centralized control resource. Since a relay station transmits the P-SCH as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.

In a base station (100) where a downlink control signal directed to a relay station is mapped onto an allocation area (R-PDCCH allocation area candidate) comprising M (where M is a natural number of 2 or greater) resource blocks, an allocation area candidate determination section (101) distributes the M resource blocks among N (where N is a natural number less than M) allocation area groups, and determines N resource block groups for the placement of the allocation area groups; and a control signal allocation section (102) maps the downlink control signal directed to the relay station onto the M resource blocks that are specified on the basis of the determined N resource block groups and the number of resource blocks constituting each of the allocation area groups.

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. An allocation unit (106) 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.

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.
