摘要:
Certain aspects of the present disclosure provide procedures for managing secondary eNB (SeNB) radio link failure (S-RLF) in dual connectivity scenarios. A user equipment (UE) may establish communication with a Master Evolved Node B (MeNB) and a Secondary eNB (SeNB). The UE may detect a Radio Link Failure (RLF) of a connection with the SeNB and may transmit an indication of the RLF to the MeNB, in response to the detection. The MeNB may take at least one action to manage the RLF, in response to receiving the indication of the RLF, for example, including transmitting a reconfiguration command to the UE. The SeNB may also detect the RLF and transmit an indication of the RLF to the MeNB over a backhaul connection, in response to the detection.
