1. An apparatus, comprising a processing element configured to cause a user-equipment (UE) device to:
establish a radio resource control (RRC) connection with a cellular base station;
provide an indication to the cellular base station of a UE-preferred discontinuous reception (DRX) cycle length for use by the UE device in an RRC inactive state; and
responsive to providing the indication of the UE-preferred DRX cycle length, configure a DRX cycle length for use by the UE device in the RRC inactive state.
