Zusammenfassung:Systems and methodologies are described that facilitate management of data delivery and processing in a wireless communication system and, more particularly, that support Packet Data Convergence Protocol (PDCP) reordering of packets during a handoff operation. Various aspects described herein can mitigate processing delays associated with PDCP reordering of packets at handoff by determining, communicating, and/or otherwise identifying one or more indicators during handoff that facilitate lossless communication of packets to a terminal with minimal delay. These indicators can include sequence number information for a source Node B, information regarding a step or jump size applied to a sequence number by a target Node B, a reset command, and/or other suitable indicators.
