1. A terminal comprising:
a receiver configured to receive a Media Access Control (MAC) Control Element (CE) and a spatial relation information identifier associated with a Physical Uplink Control Channel (PUCCH) resource; and
a processor configured to activate or deactivate a spatial relation of the PUCCH resource, based on the MAC CE received by the receiver,
wherein the MAC CE includes a serving cell ID, a BandWidth Part (BWP) ID, and a PUCCH resource ID for identifying a PUCCH group to which the PUCCH resource belongs, and the PUCCH resource,
wherein the MAC CE applies to all PUCCH resources that belong to the PUCCH group, and
wherein the spatial relation information identifier indicates a spatial setting for PUCCH transmission associated with the PUCCH resource, and the spatial setting specifies a spatial domain filter for PUCCH transmission based on a reference signal.
