Problems solved by technology

[0005] The LTE system also supports polling and status report suppression, but currently 3GPP (3rd Generation Partnership Project: 3rd Generation Partnership Project) has not discussed the specific mechanism of status report suppression, and no corresponding proposal has been proposed.

Embodiment Construction

[0020] In the LTE system, the HARQ reordering at the receiving end is performed at the AM RLC entity, and a status report is triggered when the reordering timer expires. In addition, a status report can also be triggered when the receiving end receives a poll. Therefore, the status report suppression mechanism needs to comprehensively consider the reordering timer and polling received. The main technical features of the present invention are: when the reordering timer T_reordering expires, the AM RLC entity at the receiving end triggers a status report, and if the status report suppression timer T_Status_Prohibit is running at this time, then stop and reset the status report suppression timer. The status report suppression timer may also be called by other names, and its characteristic is that during the running of the timer, the status report is not triggered due to polling or some other status report trigger conditions are met.

Abstract

An automatic retransmission request state report restriction method is applied for the mobile communication system. When a re-ranking timer is overtime, a wireless chain control layer entity which adopts a confirming mode at the receiving end triggers a state report, and if when the state report restriction timer is operating, the state report restriction time is stopped and reset. The automatic retransmission request state report restriction method disclosed by the invention comprehensively processes an RLC AM entity re-ranking timer, the state restriction timer and the polling mechanism. The frequent triggering of unnecessary state report by the receiving end is prevented. The wireless resource is saved. The total efficiency and capability of system are provided. The residual problem in LTE system is settled. The automatic retransmission request state report restriction method is suitable for the automatic retransmission request ARQ mechanism in the wireless communication system.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, in particular to an automatic retransmission request status report suppression method in a wireless communication system. Background technique [0002] The radio link control layer (RLC: Radio Link Control) of the wireless interface of the third-generation mobile communication system WCDMA (Wideband Code Division Multiple Access) includes three types of RLC entities: transparent mode (TM: Transparent Mode), unacknowledged mode (UM: Unacknowledged Mode) and confirmation mode (AM: Acknowledged Mode). The TM RLC entity and the UM RLC entity can be configured as a sending RLC entity or a receiving RLC entity, where the sending RLC entity sends a Radio Link Control Protocol Data Unit (RLC PDU: Radio Link Control Protocol Data Unit), and the receiving RLC entity receives an RLC PDU. The AM RLC entity includes a sending end and a receiving end, where the AM RLC entity at the sendin...
