A1

[Problem] To enable a terminal device to identify a beam used by a base station while suppressing use of radio resources. [Solution] This base station 100 is provided with an acquisition unit 133 for acquiring a Medium Access Control (MAC) Protocol Data Unit (PDU), and a transmission processing unit 135 for transmitting the MAC PDU via a downlink. The MAC PDU includes a plurality of identifiers, and beam-related information corresponding to each of one or more identifiers included in the plurality of identifiers, and does not include beam-related information corresponding to the other identifiers included in the plurality of identifiers.
