Abstract
(EN)
User equipment according to an aspect of the present disclosure is provided with: a transmission unit that transmits information indicating which beam correspondence using which downlink reference signal is to be supported; a reception unit that receives spatial relationship information indicating a downlink reference signal having a spatial relationship with that for a sounding reference signal; and a control unit that determines a spatial domain filter to be used for transmission of an uplink signal on the basis of a spatial domain filter used for reception of the aforementioned downlink reference signal.
