Abstract: A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface and processing circuitry coupled to the RF interface. The processing circuitry is to: cause communication with a NR evolved Node B (gNodeB) on a first bandwidth part (BWP); determine a BWP switching delay for an uplink (UL) communication from the UE to the gNodeB, the BWP switching delay based on a timing advance (TA) for the UL communication; encode the UL communication for transmission to the gNodeB; switch from the first BWP to a second BWP at an expiration of the BWP switching delay; and cause transmission of the UL communication on the second BWP.

Abstract: Embodiments of a user equipment (UE) for reporting of timing offset for dual connectivity enhancement are disclosed herein. The UE can include transceiver circuitry to connect to a master cell group via a master evolved node B (eNB) and a secondary cell group via a secondary eNB. Additionally, the UE can receive a first reference signal from the master eNB and a second reference signal from a secondary eNB. Moreover, the UE can include processing circuitry to calculate a system frame number (SFN) and subframe timing difference (SSTD) based on the first reference signal and the second reference signal. Moreover, the UE can generate a measurement report having a synchronization indicator for dual connectivity based on the calculated SSTD. Subsequently, the UE can send the generated measurement report to the master eNB.
