1. A terminal comprising:
a receiver that receives a Media Access Control (MAC) subheader and a MAC Control Element (CE), the MAC subheader being attached to the MAC CE, in a downlink shared channel from a base station; and
a processor that performs an activation, based on:
information indicating performing the activation of transmission configuration state in which up to two transmission configuration states can be associated with a same code point, the information being included in the MAC subheader, and
a value set in a field indicating whether an identifier of a second transmission configuration state associated with the same code point is present, the field being included in the MAC CE,
wherein the receiver receives downlink control information including the code point from the base station, and the processor performs quasi co-location (QCL) assumption in a downlink shared channel, based on the two transmission configuration states associated with the code point included in the downlink control information, and
wherein, when the value set in the field indicating whether the identifier of the second transmission configuration state associated with the same code point is present, the field being included in the MAC CE, is 1, the field indicates that the identifier of the second transmission configuration state associated with the same codepoint is present, and when the value set in the field indicating whether the identifier of the second transmission configuration state associated with the same code point is present, the field being included in the MAC CE, is 0, the field indicates that the identifier of the second transmission configuration state associated with the same codepoint is not present.
