摘要： A radio communication base station device can efficiently obtain a multiuser diversity gain from frequency scheduling while reducing the amount of a reference signal occupying an uplink. In the device, a grouping section (109) divides a plurality of RBs (Resource Blocks) into a plurality of RB groups. An RB group control unit (108) performs a control to change the correspondence relationship between the RBs and the RB groups with time. When the grouping section (109) divides the RBs into the RB groups, the RB control unit (108) performs a control to change a combination of the RBs included in each of the RB groups with time. A scheduling section (110) performs a scheduling of allocating each of a plurality of mobile stations to each of the RBs in each of the RB groups according to the reception quality of the reference signal.

摘要： The invention relates to methods for detecting at least one of a downlink grant and an uplink grant within a sub-frame of an OFDM-based mobile communication system. The invention provides a reception apparatus (e.g. a relay node or a mobile terminal) that are adapted to perform these methods. The invention defines the uplink grant search space to form a subset of the downlink grant search space. In other words, in the frequency domain, the uplink grant search space is defined on a subset of the resource block pairs that form the downlink search space. This configuration allows downlink data to be mapped to the remaining resources outside the uplink grants search space and the resources used for a downlink grant. Furthermore, the downlink grants comprise an indication of whether the uplink grant search space in the sub-frame comprises (user) data or not.

摘要： Provided are a transmission device and transmission method that are capable of allowing leeway in data reception processing on the receiving side regardless of the position in time of a resource region to which control information, which is contained in resource allocation information for transmission data, is mapped. A setting unit (101) sets a mapping region, which maps a DCI in accordance with the downlink data size that the DCI indicates, from among a PDCCH region, an R-PDCCH region in slot 0, and an R-PDCCH region in slot 1 that are provided in order in the time direction within a subframe. In a setting rule table used in setting the mapping region, PDCCH region, R-PDCCH region in slot 0, and R-PDCCSH region in slot 1 are associated with maximum size value of a downlink data size that the DCI indicates and that can be set in each resource region.

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： 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： 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.

摘要： A communication relay apparatus wherein the error rate characteristic of a relay destination is improved to raise the throughput, while reducing the given interference power to prevent the reduction of the throughput of the whole communication system. In the apparatus, a signal addressed to a base station is received (ST1010), and a decoding process and other processes are performed (ST1020). A bit error determination is performed (ST1030), and if there is no bit error, a reproduction/relay process (ST1050) is performed. If there is any bit error, a threshold-based determination of reception quality is performed for each of subcarriers (ST1120-1130). If the reception quality is greater than a threshold value, the corresponding subcarrier is outputted (ST1140); otherwise, the corresponding subcarrier is not relayed (ST1150). A signal, which has been subjected to either process, is transmitted (ST1060).

摘要： The present invention provides a base station whereby efficient resource allocation for data signals is realized. In a base station (100) where a downlink control signal directed to a relay station is mapped onto an allocation area (R-PDCCH allocation area candidate) comprising M (where M is a natural number of 2 or greater) resource blocks, an allocation area candidate determination section (101) distributes the M resource blocks among N (where N is a natural number less than M) allocation area groups, and determines N resource block groups for the placement of the allocation area groups; and a control signal allocation section (102) maps the downlink control signal directed to the relay station onto the M resource blocks that are specified on the basis of the determined N resource block groups and the number of resource blocks constituting each of the allocation area groups.
