Abstract:
A method used in an E-UTRAN for synchronizing PDCP operations after a RRC connection re-establishment procedure with a user equipment (UE) is provided. The method includes: initiating an RRC reconfiguration procedure to resume all radio bearers other than a signaling radio bearer 1 (SRB1) when an RRC connection is re-established; re-transmitting a designated group of PDCP Service Data Units (SDUs) to the UE when a data radio bearer (DRB) mapped on Radio Link Control (RLC) Acknowledged Mode (AM) is resumed.
