Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a power headroom (PHR) value for a component carrier (CC) based at least in part on a physical uplink shared channel (PUSCH) transmission in the CC, wherein the PUSCH transmission includes a first repetition associated with a first set of power control parameters and a second repetition associated with a second set of power control parameters, and wherein the PHR value is determined based at least in part on one or more of the first repetition or the second repetition. The UE may transmit information identifying the PHR value for the CC. Numerous other aspects are provided.
