摘要： A receiver having an array antenna estimates arrival directions of multiple paths that arrive with an angular spread. Consequently, arrival direction estimation accuracy can be ensured without increasing throughput even if the power every path is low by estimating an average arrival direction of an entire set of multiple paths having the angular spread from a result of one angular spectrum by multiple correlation operation units that perform mutual correlation operations with pilot signals for baseband signals received by the array antenna, a path detection unit that detects multiple arrival path receiving timings by generating a delay profile based on output of each of the correlation operation units, a path correlation value synthesis unit that synthesizes a correlation operation value calculated in the multiple correlation operation units and an arrival direction estimation unit that collectively estimates multiple path arrival directions using output of the path correlation value synthesis unit.

摘要： A transmission weight computing section computes a transmission weight for directional transmission using an OFDM signal. A transmission correcting value memory section stores one correcting value for correcting the transmission weight for each sub-carrier of an OFDM signal or each band gathering a plurality of sub-carriers.

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： 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。
