3. A base station comprising:
a transmitter that transmits downlink control information including a field used to indicate a transmission configuration indication (TCI) state; and
a processor that, in response to a parameter, which indicates a plurality of downlink (DL) TCI states or a plurality of uplink (UL) TCI states, being configured via higher layer signaling and a spatial relation not being configured per sounding reference signal (SRS) resource, indicates, based on a same codepoint of the field, a DL TCI state for a DL channel and an UL TCI state for the SRS resource,
wherein the plurality of DL TCI states and the plurality of UL TCI states are indicated by the parameter via the higher layer signaling, and the base station supports an index of the DL TCI state for the DL channel and an index of the UL TCI state for the SRS resource being configured differently for the codepoint.
