RADIO LINK FAILURE MANAGEMENT IN WIRELESS COMMUNICATION NETWORKS

Abstract:

In some aspects, methods, apparatuses, and computer program products are provided for handling RLC failures in PDCP duplication where there are two logical channels on which a PDCP entity can send packets. In some aspects, the radio network node may determine a mapping between the primary and secondary logical channels and serving cells, and how this mapping can be configured for the wireless device. In some aspects, the wireless device may take different actions depending on which of a primary and a secondary logical channel, i.e. RLC entity, fails. In some aspects, the wireless device operating in PDCP duplication may notify the radio network node about the failure of a radio link supporting the secondary logical channel without triggering the RLF procedure.
