摘要： Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unit 16 determines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.

摘要： The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.

摘要： Provided are a terminal device and a retransmission control method that make it possible to minimize increases in overhead in an uplink control channel (PUCCH), even if channel selection is used as the method to transmit response signals during carrier-aggregation communication using a plurality of downlink unit bands. On the basis of the generation status of uplink data and error-detection results obtained by a CRC unit, a control unit in the provided terminal uses response signal transmission rules to control the transmission of response signals or uplink control signals that indicate the generation of uplink data. If an uplink control signal and a response signal are generated simultaneously within the same transmission time unit, the control unit changes the resources allocated to the response signal and/or the phase point of the response signal in accordance with the number and position of ACKs within the error-detection result pattern.

摘要： A base station, a terminal, a transmission method and a reception method that allow the data processing on a reception side to have a margin irrespective of the time position of a resource region where control information is mapped. In a base station (100), a subframe type determining unit (101) determines, according to a configuration pattern applied to the local base station apparatus and being one of a plurality of configuration patterns different between downlink and uplink subframe configurations in time division multiplex, whether a subframe to be determined is a first type of subframe where control information is mapped only to a PDCCH region or a second type of subframe where the control information is mapped to both the PDCCH region and an R-PDCCH region. An allocation region candidate determining unit (102) determines, based on a result of the determination by the subframe type determining unit (101), a mapping region, where the control information is mapped, in the PDCCH or R-PDCCH region in the subframe to be determined.

摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.

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 relay device and a wireless relay method are provided which can improve the utilization efficiency of resources. In the wireless relay device for relaying a signal between a base station and a mobile station, if a transmission section transmits an SRS in a subframe immediately previous to the backhaul subframe, an SRS setting section sets a last symbol of an access link subframe as a fake symbol in which the SRS that the mobile station transmits to the wireless relay device is not configured. A reception section receives the signal transmitted from the mobile station to the wireless relay device in a previous symbol of one of the fake symbol, and then a switching section switches to transmission from the wireless relay device to the base station. If the transmission section does not transmit the SRS in the backhaul subframe immediately previous to the backhaul subframe, the reception section receives the signal transmitted from the mobile station to the wireless relay device in the last symbol of the access link subframe, and then the switching section switches to transmission from the wireless relay device to the base station.

摘要： There are provided a wireless transmitting apparatus and a wireless transmission method that enable reduction of transmission delay of a system by enhancing receiving performance achieved during transmission of network-coded data. A decoding section 18 subjects a demodulated signal to error correction decoding and outputs the decoded signal to a buffer 17. The buffer 17 holds a data packet for a given period of time and outputs the packet to an encoding section 12. An encoding control section 11 controls an encoding rate for transmission data and outputs control information to the encoding section 12. In accordance with control information from the encoding control section 11, the encoding section 12 subjects a data packet to error correction encoding and outputs the coded data packet to a coding section 13. The coding section 13 subjects data sequences that pair up with each other to XOR processing and outputs a processing result to a modulation section 14. A wireless transmission section 15 subjects a modulated signal to transmission processing, such as digital-to-analogue conversion, up-conversion, and amplification, and transmits the signal subjected to transmission processing from an antenna 16 through wireless communication.
