Inter-Radio Access Technology Carrier Aggregation

A user device comprising:

• a hardware-based transceiver;
• and
• an inter-radio access technology carrier aggregation (Inter-RAT CA) module configured to perform operations comprising:
• establishing, via the transceiver of the user device, a wireless link with one or more base stations, the wireless link including:
• a first component carrier of a first radio access technology (RAT);
• and
• a second component carrier of a second RAT, the second RAT being different from the first RAT;
• receiving, from the one or more base stations and via the first component carrier of the first RAT, an inter-RAT carrier aggregation communication, the inter-RAT carrier aggregation communication providing data relating to the second component carrier of the second RAT;
• and
• altering, in response to receiving the inter-RAT carrier aggregation communication, a configuration of the second component carrier of the second RAT.

A method performed by a base station of a wireless network, the method comprising:

• establishing, via a transceiver of the base station, a wireless link for communicating with a user device, the wireless link including a first component carrier of a first radio access technology (RAT) facilitating communication between the base station and the user device;
• determining that the user device supports a second component carrier of a second RAT;
• receiving, from another device of the wireless network, data relating to the second component carrier of the second RAT;
• and
• transmitting, to the user device via the first component carrier of the first RAT, an inter-RAT carrier aggregation communication providing at least a portion of the data relating to the second component carrier of the second RAT, the portion of the data usable by the user device to configure a transceiver of the user device for future communication via the second component carrier of the second RAT.
