Inter-RAT mobility of in-device coexistence

摘要

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.

主权项

1. At least one non-transitory machine-readable medium including instructions for execution on circuitry of a user equipment (UE), which when executed by the UE, cause the UE to perform electronic operations for management of evolved UMTS Terrestrial Radio Access Network (E-UTRAN) handover that:
perform measurements, at the UE, to determine in-device coexistence (IDC) interference occurring with radio communications of the E-UTRAN; and transmit an indication of the IDC interference to a radio access network; wherein a UMTS Terrestrial Radio Access Network (UTRAN) or a GSM EDGE Radio Access Network (GERAN) refrains from performing a handover from the UTRAN or the GERAN to the E-UTRAN in response to the indication of the IDC interference.
