Systems and methodologies are described that facilitate configuring a flush timer within a wireless environment in order to provide robust communications in regards to handover or re-establishment. The flush timer can be triggered upon successful completion of reconfiguration re-establishment. Moreover, the flush timer can be triggered upon successful completion of handover. In the case of handover and re-establishment, a separate indication of handover to packet data convergence protocol (PDCP) from the start of PDCP flush timer can be utilized.
