    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: 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.

    摘要: Provided is a mobile communication system capable of eliminating the use of a control channel for transmitting specific area information and suppressing the overhead caused by a frequency change process for a mobile station to receive the specific area information. In the mobile communication system, a relay station (20) has a coverage area (21) (specific area) and relays and transmits, in the coverage area (21), a signal received from a base station (10) to a mobile station (30). The relay station (20) adds, to the signal received from the base station (10), the offset of any of a frequency offset, a time offset, and a power offset depending on a risk indicated by risk information in the coverage area (21) (specific area) and transmits the signal after the addition of the offset to the mobile station (30) located in the coverage area (21).
