Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station in a full duplex mode, a first downlink transmission associated with a spatial filter. The UE may decode the first downlink transmission according to a default transmission configuration indicator (TCI) state that indicates the spatial filter. The default TCI state may be based at least in part on a first active TCI state for the full duplex mode. Numerous other aspects are provided.
