    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.

    摘要: A method and apparatus are disclosed for prioritizing logical channels when a new transmission is performed. Logical channel resources are allocated for available data to a plurality of logical channels. A maximum bit rate (MBR) credit (i.e., token) is decremented in a buffer (i.e., bucket) associated with a particular one of the logical channels by the size of a medium access control (MAC) service data unit (SDU). The MBR credit may have a negative value. If any of the allocated channel resources remain, the logical channels are served n a decreasing priority order until the data is exhausted. A radio link control (RLC) SDU is not segmented if the whole RLC SDU fits into the remaining resources. The MAC SDU excludes a MAC PDU header and MAC padding.

    摘要: A method and apparatus for discarding a packet data convergence protocol (PDCP) service data unit (SDU) are disclosed. A PDCP layer sets a timer and discards a PDCP SDU upon expiration of the timer. The timer may be set upon receiving the PDCP SDU from an upper layer or upon submitting the PDCP SDU to a lower layer for transmission. The timer and a radio link control (RLC) discard timer may be coordinated. Alternatively, the PDCP layer may discard the PDCP SDU based on a notification from an RLC layer or based on a PDCP status report.

    摘要: A method and apparatus for triggering radio link control (RLC) re-establishment and/or protocol data unit (PDU) discard are disclosed. An RLC entity maintains a state variable for counting a total number of transmissions and/or retransmissions of an RLC PDU and its PDU segments. If the state variable reaches a threshold, the RLC entity initiates RLC re-establishment and/or discards the RLC PDU and PDU segments. The state variable may be incremented each time a negative acknowledgement is received for at least a portion of the RLC PDU or when a retransmission is considered for the RLC PDU or a portion of the RLC PDU. The RLC entity may increase a state variable proportionate to a retransmitted data size. The RLC entity may maintain separate state variables for the RLC PDU and PDU segments and counts the number of transmissions and/or retransmissions for the RLC PDU and the PDU segments.
