  • Publication number: 20240298316
    Abstract: Provided is a mobile station that can appropriately allocate resources in an unlicensed band. In the mobile station (200), on the basis of resource association between an uplink reference signal and another uplink signal different from the reference signal, a control unit (205) determines a frequency resource to be used for uplink transmission. A transmission unit (209) uses the frequency resource to transmit at least one of the reference signal and the other uplink signal.
