1. A method of processing data at an apparatus in a wireless communication system, the method comprising:
- receiving a Packet Data Convergence Protocol Service Data Unit (PDCP SDU) at the apparatus;
starting a discard timer for the PDCP SDU at the apparatus when receiving the PDCP SDU;
when the discard timer for the PDCP SDU expires, discarding the PDCP SDU at the apparatus; and
if a Radio Link Control Service Data Unit (RLC SDU) related with the PDCP SDU is present in the apparatus and if the RLC SDU is not mapped to an RLC Protocol Data Unit (RLC PDU), discarding the RLC SDU at the apparatus.
