ABSTRACT:
Whenever the Receiver of this invention receives an AMD PDU or a UMD PDU with its “Length Indicator” having an invalid or a reserved value, the Receiver discards such a PDU and treats it as never received. The Receiver may report its receiving status accordingly if a report is required. This invention avoids invoking unnecessary RLC reset procedures and reduces the chance of losing HFN synchronization during AM or UM data transmissions.
