Abstract
Systems and techniques for link failure management in multiple connection systems. Upon detection of a link failure with a local area base station during a dual connection mode in which the user device is connected to a macro base station and a local area base station, a user device sends a failure indication and a measurement results report for serving and neighboring base stations to its serving macro base station, and selects a response to the failure based at least in part on evaluation information received from the macro base station. Upon detection of a link failure with a macro base station, the user device determines whether to reconnect to the macro base station or a different macro base station and whether to reconnect with the original local area base station or a different local area base station.
