Certain aspects of the present disclosure provide techniques for beam indication set reuse. A method for a wireless communication that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a beam indication set. The method includes receiving an indication to apply the configured beam indication set to multiple bandwidth parts (BWPs) and/or multiple component carriers (CCs). The method includes applying the beam indication set to a BWP or CC based on the indication. The beam indication set may be for uplink or downlink communications. The beam indication set may be a transmission configuration indicator (TCI) state set or spatial relation set. Other aspects and features are also claimed and described.
