1. An apparatus, comprising:

  • a memory; and

    logic, at least a portion of which is implemented in circuitry coupled to the memory, the logic to;

    determine, based on a message received at a master evolved node B (MeNB) of a master cell group (MCG) for dually-connected user equipment (UE), a system frame number (SFN) and a subframe number, the SFN and the subframe number associated with a system timing of a secondary evolved node B (SeNB) of a secondary cell group (SCG) for the dually-connected user equipment UE, wherein the system timing of the SeNB is not synchronized with a system timing of the MeNB;

    based on the SFN and the subframe number, select one or more MCG discontinuous reception (DRX) parameters to at least partially align MCG DRX operations of the dually-connected UE with SCG DRX operations of the dually-connected UE, the one or more MCG DRX parameters to comprise parameters controlling MCG DRX operations of the dually-connected UE;

    generate a radio resource control (RRC) message comprising information identifying the one or more MCG DRX parameters; and

    send the RRC message to a radio frequency (RF) interface for transmission to the dually-connected UE.
