Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, signaling that indicates a relative power difference between a first cell and a second cell. The UE may apply the relative power difference in a transmission occasion that includes at least a first uplink transmission on the first cell and a second uplink transmission on the second cell, wherein applying the relative power difference causes the first uplink transmission on the first cell to be transmitted at a lower power level than the second uplink transmission on the second cell. Numerous other aspects are described.
