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 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： To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3

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.
摘要翻译：提供了可以提高资源利用效率的无线中继装置和无线中继方式。在用于在基站和移动台之间中继信号的无线中继装置中，如果传输部分在紧接回程子帧之前的子帧中发送SRS，则SRS设置部分将接入链路子帧的最后一个符号设置为未配置移动台向无线中继装置发送的SRS的伪符号。一个接收部分在假冒符号之一的先前符号中接收从移动台发送到无线中继设备的信号，然后切换部分切换到从无线中继设备到基站的传输。如果传输部分在紧接回程子帧之前的回程子帧中不发送SRS，则接收部分在接入链路子帧的最后一个符号中接收从移动台向无线中继设备发送的信号，然后切换切换到从无线中继设备到基站的传输。

摘要： To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus (eNB) transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses (UE1, UE2). Each of the reception apparatuses (UE1, UE2) detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe.
