Abstract

Certain aspects of the present disclosure relate to techniques for managing radio link failure recovery for a user equipment (UE) connected to a WWAN and a WLAN. The techniques may include establishing communication with a first radio access technology (RAT) and a second RAT. At least one data flow may be transmitted over each of the first RAT and the second RAT. Determinations may be made as to whether to maintain the at least one data flow over the second RAT when a radio link failure (RLF) is detected at the UE and/or whether to resume the at least one data flow over the second RAT upon RLF recovery. The determinations may be made at the UE, at a network entity in communication with the UE, or some combination thereof.
