Abstract: Some techniques described herein provide indication of a preferred scheduling mode for a user equipment (UE) based at least in part on an energy harvesting state of the UE. For example, the preferred scheduling mode may indicate a configured grant scheduling mode or a dynamic grant scheduling mode and/or one or more parameters associated with the preferred scheduling mode. For example, the one or more parameters may be based at least in part on an energy harvesting state of the UE.
