Abstract
A method and apparatus are described for implementing a reset procedure for radio link control (RLC) using radio resource control (RRC) signaling. A wireless transmit/receive unit (WTRU) receives a request for RLC reset. A processor at the WTRU comprises a RRC entity and a RLC entity. The RRC entity receives the request for a RLC reset in a radio resource control message. The RLC entity reassembles RLC service data units (SDUs) from any protocol data units (PDUs) that are received out of sequence at a receiving side of the RLC entity. The reassembled SDUs are delivered in sequence to a packet data convergence protocol entity (PDCP). At the receiving side of the RLC entity, any remaining PDUs that are not able to be reassembled are discarded. At a transmitting side of the RLC entity, all SDUs and PDUs stored in transmit buffers are discarded.
