Apparatus, methods, and computer-readable media for autonomous physical uplink shared channel repetition cancellation for energy-limited devices are disclosed herein. A user equipment (UE) may transmit, to a base station, a plurality of uplink channel repetitions. The UE may determine that a device power level associated with the UE does not exceed a predetermined threshold that corresponds to a power requirement to transmit a number of uplink channel repetition instances in the plurality of uplink channel repetitions. The UE may determine to not transmit the number of uplink channel repetition instances based on the device power level falling below the predetermined threshold. The UE may modify the device power level through an energy harvesting operation. Thus, the power efficiency and reliability of uplink channel repetitions can be increased.
