Abstract: 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).

Abstract: In a base station (100), a division number calculating unit (103) calculates the division number of a PRB pair on the basis of a first number of REs capable of mapping an allocation control signal, a second number of REs capable of mapping signals other than the allocation control signal, and a reference value, which is the number of REs satisfying the reception quality request in a terminal (200) for the allocation control signal, in each PRB pair. Then, a control signal mapping control unit (104) determines a search space by determining a control channel element group constituting a plurality of mapping unit resource region candidates within a CCE group obtained by separating each PRB pair contained in a first group into the same number as the division number.

Abstract: Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).

Abstract: A radio communication terminal that increases the ACK/NACK resource utilization efficiency while preventing ACK/NACK collision, and that causes no unnecessary reduction of the PUSCH band in a system that transmits E-PDCCH control information. The radio communication terminal adopts a configuration including a receiving section that receives a control signal including an ACK/NACK index via an enhanced physical downlink control channel (E-PDCCH) transmitted using one configuration from among one or a plurality of configuration candidates, a control section that selects a resource to be used for an ACK/NACK signal of downlink data from among specified resources specified beforehand based on E-PDCCH configuration information used for transmission or reception of the E-PDCCH and the ACK/NACK index, and a transmitting section that transmits the ACK/NACK signal using the selected specified resource.
