Abstract: Embodiments of system, device, and method configurations for managing inter-radio access technology (inter-RAT) mobility of handovers between a UMTS Terrestrial Radio Access Network (UTRAN) or GSM EDGE Radio Access Network (GERAN) and an evolved UMTS Terrestrial Radio Access Network (E-UTRAN) to avoid scenarios of in-device coexistence (IDC) interference are disclosed herein. In one example, the existence and types of IDC interference with an E-UTRAN Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A) network are determined and communicated to the UTRAN/GERAN in an IDC indication signal. The IDC indication signal may communicate the existence and type of IDC interference occurring at user equipment, such as between licensed LTE/LTE-A and unlicensed industrial scientific medical (ISM) radio frequency bands. Accordingly, the UTRAN/GERAN may use information provided from the IDC indication signal to prevent a handover to the E-UTRAN that would result in IDC interference.

In some examples, Bluetooth scheduler can dynamically change the timing of the scheduling algorithm such that it may utilize the knowledge of LTE traffic and may at least partially avoid interference or evaluate the interference level.
