Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a primary cell (Pcell) and a secondary cell (Scell) of a service network. The controller activates duplication of Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) for Carrier Aggregation (CA) using a plurality of Radio Link Control (RLC) entities. In response to detecting that an RLC failure of one of the RLC entities, which is not associated with the Pcell, has occurred, the controller sends a Radio Resource Control (RRC) message for reporting the RLC failure to the service network via the wireless transceiver.

Abstract: Aspects of the disclosure provide a processing circuit in an electronic apparatus and a method to switch the electronic apparatus during an inter-system handover (HO) process from a source network system to a target network system. The processing circuit can include an inter-system HO signal processing module and a mapping module. The inter-system HO signal processing module can be configured to obtain a mapping relationship between a set of source bearers associated with the source network system and a first set of target bearers associated with the target network system based on quality of service (QoS) characteristics associated with the set of source bearers and the first set of target bearers. The mapping module can be configured to obtain a second set of target bearers based on resources allocated to the first set of target bearers by the target network system and to obtain a third set of target bearers that is based on the first and second set of target bearers.
