1. Master enhanced node B (MeNB) circuitry comprising:
- determination circuitry to;
determine a difference between a system frame number (SFN) of a secondary cell group (SCG) and a SFN of a master cell group (MCG); and
determine a difference between the subframe number of the SCG and a subframe number of the MCG; and
alignment circuitry, coupled with the determination circuitry, to;
configure a gap offset to align a discontinuous reception (DRX) or measurement gap of the SCG with a DRX or measurement gap of the MCG.
