A base station (100) can execute communication using the uplink unit band and a plurality of downlink unit bands correlated to the uplink unit band. The base station (100) includes: a PDCCH generation unit (102) which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit (103) which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size.

摘要： It is possible to provide a radio resource management device, a radio communication base station device, and a radio resource management method which can reduce a reply signal inter-cell interference and suppress decrease of the number of ACK/NACK which can be transmitted. When a plurality of CCE are allocated for PDCCH transmission, among usable CCE, the CCE number used between adjacent cells is differentiated. More specifically, a different RN satisfying RN=(usable CCE number m) mod N is allocated to the adjacent cell. A mobile station performs ACK/NACK transmission by using a PUCCH resource corresponding to the CCE number which becomes the allocated RN.

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： Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).

摘要： A wireless communication base station apparatus which is able to prevent deterioration in the throughput of LTE terminals even when LTE terminals and LTE+ terminals coexist. In this apparatus, based on the mapping pattern of the reference signals used only in LTE+ terminals, a setting unit (105) sets, in each subframe, the resource block groups where the reference signals used only by the LTE+ terminals are mapped. For symbols mapped to the antennas (110-1 to 110-4), an mapping unit (106) maps, to all the resource blocks within one frame, cell specific reference signals used for both LTE terminals and LTE+ terminals. For the symbols mapped to the antennas (110-5 to 110-8), the mapping unit (106) maps, to the plurality of resource blocks, of which part of the resource block groups is comprised, in the same subframe within one frame, the cell specific reference signals used only for LTE+ terminals, based on the setting results inputted from the setting unit (105).
