Apparatuses and methods for handling a radio link control (rlc) failure

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.
