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.
