Title:
無線リンク制御パケットの破棄および無線リンク制御の再確立をトリガする方法および装置
Document Type and Number:
Japanese Patent JP5841989
Kind Code:
B2
Abstract:
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.
