Abstract: Various embodiments of the present disclosure describe a terminal and a base station. Various embodiments of the present disclosure describe how to transmit the SRS on an FDD downlink carrier and effectively configure and transmit the FDD downlink carrier SRS, so that the FDD system has the channel reciprocity and is more suitable for a large-scale multi-antenna system. Various embodiments of the present disclosure describe an SRS transmission method and device when an uplink carrier of the FDD system can transmit an uplink signal and a downlink signal.
