1. A method of processing data at a transmitting end in a wireless mobile communication system, the method comprising the steps of:
- receiving at a Packet Data Convergence Protocol (PDCP) layer a first data block from an upper layer;
generating a second data block including the first data block at the PDCP layer;
discarding the second data block present in the PDCP layer if a certain period of time has passed; and
transferring information associated with the discard of the second data block from the PDCP layer to a Radio Link Control (RLC) layer if the second data block has already been transferred from the PDCP layer to the RLC layer,wherein the information associated with the discard indicates that the second data block has been discarded at the PDCP layer or instructs the RLC layer to discard the second data block.

Abstract
A method in which a user equipment processes data in a wireless mobile communication system is provided. The method includes the steps of receiving a first data block from an upper layer, transferring a second data block including the first data block to a lower layer at a particular protocol layer, discarding the first and second data blocks present in the particular protocol layer if a certain period of time has passed, and transferring information associated with the discard of the second data block to the lower layer.

11. An apparatus for use in a wireless mobile communication system, the apparatus comprising:
-
an upper entity; a Packet Date Convergence Protocol (PDCP) entity below the upper entity; and Radio Link Control (RLC) entity below the PDCP entity, wherein the PDCP entity is configured; to receive a first data block from the upper entity; to generate a second data block including the first data block at the PDCP entity; to discard the second data block present in the PDCP entity if a certain period of time has passed; and to transfer information associated with the discard of the second data block to an RLC entity if the second data block has already been transferred from the PDCP entity to the RLC entity, wherein the information associated with the discard indicates that the second data block has been discarded at the PDCP entity or instructs the RLC entity to discard the second data block. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
