Embodiment Construction

[0044] As mentioned in the background, in order to ensure reliability of link data transmission, base station equipment generally adopts AM mode for transmission. In the process of data transmission, the sender adds the necessary control protocol overhead to the high-level data and then transmits it, and ensures that it is delivered to the peer entity. Because the RLC layer at the receiving end has automatic repeat request (ARQ) capability, if the RLC layer at the receiving end receives an incorrect RLC message or the received RLC message is incomplete, it will notify the RLC layer at the sending end to retransmit the wrong RLC message. text, RLC message not received. Moreover, the receiving end processes the received data of the sending end at the RLC layer based on the RLC protocol and transmits it to the PDCP layer, and sends a status report to the sending end according to the received data, and requires the sending end to repeat the transmission of the unreceived data unti...

Abstract

The present application relates to a data retransmission method, device, storage medium and network equipment thereof. The data retransmission method includes: reading packet loss information of unprocessed RLC uplink lost messages, and the packet loss information includes RLC loss Packet identifier and first packet loss time; according to the first packet loss moment and the current moment, determine the time-consuming retransmission of the RLC uplink lost message corresponding to the RLC packet loss identifier; if the retransmission time-consuming is greater than the preset delay value, then send a request to stop retransmitting the RLC uplink lost packet corresponding to the RLC packet loss identifier. This solves the technical problem of waste of air interface resources in the traditional technology, and further advances the RLC data transmission process, reduces unnecessary repeated transmission, and improves the utilization efficiency of transmission resources for uplink services.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data retransmission method, device, storage medium and network equipment thereof. Background technique [0002] In the field of mobile communication technology, base station equipment is deployed under the operator's core network, and the rate experience it provides to mobile terminal customers is affected by each node device in the entire transmission process. LTE air interface layer protocols include PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol), RLC (Radio Link Control, Radio Link Control) and MAC (Media Access Control, Media Access Control) protocols. Among them, RLC provides configurable modes for acknowledged mode (AM mode) transmission and unacknowledged mode (UM mode). When RLC is configured in AM mode, the RLC receiving end needs to send a status report to the RLC sending end according to its own reception of the RLC PDU...
