## Abstract

Methods, systems, and devices for wireless communications are described. The techniques described herein support dynamically indicating uplink control channel repetition multiple different types of uplink signaling. A user equipment (UE) may receive first control signaling indicating a first repetition factor for transmission of a feedback message associated with a beam or transmission configuration indicator (TCI) state. The UE may receive second control signaling scheduling transmission of a control message associated with the beam or TCI state. The UE may transmit, in accordance with a second repetition factor, the control message based at least in part on both the feedback message and the control message being associated with the beam. In some cases, the second repetition factor may be configured with the second control signaling.
