Method for processing radio link failure and apparatus therefor

Abstract:

Provided are a method and an apparatus for processing a Radio Link Failure (RLF) when duplicate data transmission is performed via single-BS-based CA. The method of processing an RLF by a user equipment (UE) may include: receiving, from a Base Station (BS), higher layer signaling including information for configuring duplicate data transmission via single BS-based CA; configuring a logical channel restricted to one or more secondary cells and a Radio Link Control (RLC) entity for duplicate transmission, based on the higher layer signaling; and transmitting, to the BS, a secondary cell failure report without performing RRC re-establishment procedure, when an RLF occurs in the RLC entity.
