  • Publication number: 20200275323
    Abstract: Techniques and apparatuses are described for managing inter-radio access technology capabilities of a user equipment. A base station (gNB base station 121) receives a New Radio capability information element (information element 500) that indicates one or more core networks supported by the user equipment (UE 110). Based on the New Radio capability information element, the base station generates a measurement configuration and sends measurement configuration to the user equipment (at 1010). Afterwards, the base station receives one or more measurement results based on the measurement configuration (at 1030). The base station then determines a handover type for the user equipment (at 1105, at 1205, at 1305), and initiates the handover based on the determined handover type (at 1110, at 1210, at 1310).
