5G networks allow a user equipment (UE) such as a smartphone to connect to the network via different component carriers, but this can undesirably increase UE power consumption. To reduce power consumption, the UE selectively turns off 5G for individual component frequencies based on the available resources and slots associated with each component frequency. The UE detects the downlink and uplink resource blocks and slots for each component frequency, and if the resource blocks or slots are below corresponding thresholds, turns off 5G for the carrier.
