Abstract
Official abstract text for this publication.
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 (SRB 1 ) 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A communication device of a wireless communication system for synchronizing Packet Data Convergence Protocol (PDCP) operations with another communication device, the communication device comprising: means for performing a Radio Resource Control (RRC) reconfiguration procedure to resume a data radio bearer (DRB) other than a signaling radio bearer 1 (SRB 1 ) when an RRC connection is re-established; and means for transmitting PDCP Service Data Units (SDUs…
