Abstract  Abstract

Method and an apparatus for activating a packet data convergence protocol (PDCP) reordering in a wireless transmit receive unit (WTRU) which receives a handover command message, resets a radio link control (RLC) entity of the WTRU, collects a PDCP sequence number (SN) and a range of the SN of out-of-sequence service data units (SDUs), reports the PDCP SN to a radio resource control (RRC) layer of the WTRU, transmits a handover confirm message along with a first unacknowledged PDCP SN uplink (UL), and activates the PDCP reordering based on the PDCP-SN-UL is disclosed. The WTRU includes PDCP entity including a control plane (C-plane) and a user plane (U-plane). Also, a robust header compression (RoHC) entity, a user ciphering entity, and an entity for the user plane data/control is also described.
