1. An apparatus to be employed in a user equipment (UE), comprising:configuration circuitry to: determine, based on one or more configuration information messages, a measurement gap for a master evolved Node B (MeNB) that is to provide a master cell group (MCG) that is asynchronous with a secondary cell group (SCG) of a secondary evolved Node B (SeNB), wherein subframe boundaries of the MCG are offset from subframe boundaries of the SCG, wherein a starting point of the measurement gap has a first system frame number (SFN) and a first subframe number, wherein a starting point of an interruption gap for the SeNB has a second SFN and a second subframe number, and wherein subframe timing of the MeNB is ahead of subframe timing of the SeNB such that the second subframe number is immediately ahead of the first subframe number; and
radio frequency (RF) control circuitry to:
tune, at a beginning of the measurement gap based on a subframe boundary of the MCG and independent of a subframe boundary of the SCG, RF circuitry to start inter-frequency measurements, wherein the RF circuitry is to transmit or receive data in a serving cell of the MCG and in a serving cell of the SCG; and
re-tune, at an end of the measurement gap, the RF circuitry to transmit or receive data in the serving cell of the SCG or the MCG, wherein a time from a start of the tuning to an end of the re-tuning is aligned between the MCG and the SCG.
