METHOD AND APPARATUS FOR HANDLING RLC STUCK PROBLEM IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method of processing signals by a Packet Data Convergence Protocol (PDCP) entity associated with two or more Radio Link Control (RLC) entities of a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: detecting a RLC stuck problem in one RLC entity of the two or more RLC entities; transmitting an indicator related to the RLC stuck problem to a network; and resetting the one RLC entity having the RLC stuck problem, wherein the RLC stuck problem comprises a difference between the PDCP sequence number (SN) of PDCP Protocol Data Unit (PDU) transmitted by the one RLC entity and the PDCP SN of the PDCP PDU transmitted by another RLC entities being larger than a threshold value.
