Abstract: Apparatuses, systems, and methods for a wireless device to manage an uplink bearer that utilizes concurrent inter-RAT dual uplink connectivity to avoid packet loss during bearer switch, handover, and/or radio link failure occasions. The wireless device may establish a first wireless link according to a first radio access technology (RAT) and a second wireless link according to a second RAT. A data bearer may be established that utilizes both the first wireless link and the second wireless link. Uplink data packets of the data bearer that are provided to a protocol stack for the second RAT may be stored in a buffer. The second wireless link may be lost. The stored uplink data packets that were provided to the protocol stack for the second RAT may be provided to a protocol stack for the first RAT based at least in part on the second wireless link being lost.
