Radio link control reset using radio resource control signaling

摘要

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.

1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
a radio resource control message (RRC) entity initiating re-establishment of a radio link control (RLC) entity; the RLC entity reassembling RLC service data units (SDUs) from RLC protocol data units (PDUs) that are received out of sequence at a receiving side of the RLC entity based on the RLC re-establishment; the RLC entity delivering reassembled RLC SDUs in sequence to a packet data convergence protocol (PDCP) entity based on the RLC re-establishment; and the RLC entity discarding at the receiving side of the RLC entity any remaining RLC PDUs that are not able to be reassembled based on the RLC re-establishment.
