摘要： Provided are a base station, whereby the erroneous detection of control information can be reduced, thereby preventing the degradation of the system throughput. A base station (100) maps a downstream allocation control information unit, which is addressed to a terminal (200), to a first resource region, which can be used for any of a downstream control channel region and a downstream data channel region, or to a second resource region, which can be used only for the downstream control channel, so as to transmit the downstream allocation control information unit. In the base station (100), a control unit (102) establishes a scale of the PDCCH region, and a transmission region establishing unit (131) establishes, on the basis of a scale value established by the control unit (102), a mapping region to which the DCI is mapped within the R-PDCCH region and the PDCCH region.

摘要： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.

摘要： This invention provides a terminal apparatus that can suppress the quality degradation caused by a propagation path variation when implementing a retransmission control method using non-adaptive HARQ in a wireless communication system utilizing the MIMO communication technique. In this apparatus, a number-of-retransmissions counting unit (105) counts a number of retransmission requests (L) for the same code word. A predetermined precoder designating unit (106) changes precoders between when the number of retransmission requests (L) is less than N and when the number of retransmission requests (L) is equal to or greater than N plus one. A PDCCH generation unit (211) determines, based on a result of comparison between the number of retransmission requests (L) for the same CW and the number of retransmission requests (N) established for the change of precoders, a precoder to be used by terminals, and further allocates, based on the determined precoder, resources to the plurality of terminals.

摘要： Disclosed is a wireless communication device that can suppress an increase in power consumption of a terminal while preventing the degradation of SINR measurement precision resulting from TPC errors in a base station. A terminal (100) controls the transmission power of a second signal by adding an offset to the transmission power of a first signal; an offset-setting unit (106) sets an offset correction value in response to a transmission time gap between a third signal transmitted the previous time and the second signal transmitted this time; and a transmission power control unit (111) controls the transmission power of the second signal using the correction value.

摘要： Provided is a terminal apparatus that can suppress the increase in interference between pilot signals in the same slot, while also suppressing the degradation of the flexibility to design cell cluster structures. When hopping information indicates an inter-slot hopping, a mapping unit (212) arranges a first pilot sequences in which a group to which the sequences used in respective slots belong varies on a slot-by-slot basis. When the hopping information indicates an inter-subframe hopping, the mapping unit (212) arranges a second pilot sequences in which a group to which the sequences used in respective slots belong varies on a subframe-by-subframe basis. The sequence group to which the sequences used in any one of the subframes in the second pilot sequences belong is identical with the sequence group to which the sequence used in any one of the slots included in that one subframe in the first pilot sequences belongs.

摘要： Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

摘要： Disclosed is a base station which can prevent degradation in the reception characteristics of nearby cells when carrier aggregation and channel selection are applied. In accordance with the resistance to interference of a plurality of uplink component carriers of a femtocell, a response protocol controller (101) in a base station (100) changes combination rules for the uplink component carriers and signal points which a terminal (200) in a microcell covered by the base station (100) uses in the feedback of a response signal. Information in relation to the combination rules is notified to the terminal (200). A controller (217) in the terminal (200) changes the combination rules for the uplink component carriers and the signal points of the microcell covered by the base station (100) in accordance with the information notified from the base station (100), and controls transmission of the response signal in accordance with said rules.

摘要： A radio transmission apparatus performs communications with high transmission efficiency. In this apparatus, a modulator modulates data and outputs to a first spreader. A second modulator modulates data under a modulation scheme having a higher M-ary number than the first modulator and outputs the modulated data to a second spreader. The first spreader spreads the data and outputs the spread data to a frequency domain mapping section. The second spreader spreads the data and outputs the spread data to a time domain mapping section. A frequency domain mapping section maps chips with spread data on subcarriers in the frequency domain and outputs the data with chips mapped on subcarriers to an IFFT section. The time domain mapping section maps chips with spread data on subcarriers in the time domain and outputs the data with chips mapped on subcarriers to the IFFT section.
