Data transmission method and device, related equipment and storage medium

Abstract

The invention discloses a data transmission method and device, sending end equipment, receiving end equipment and a storage medium. The method comprises the following steps: sending end equipment sends a data packet; wherein in the sent data packet, in a first protocol layer of the sending end equipment, a packet header of a protocol data unit (PDU) is at a first position; the first position is other positions, except a starting position, of a service data unit (SDU) received from an upper protocol layer; the first protocol layer comprises a protocol layer which is located below an internet protocol (IP layer) and above a protocol layer using an IP PDU packet header; the initial position comprises the position of the packet header of the IP PDU in the SDU.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a data transmission method, device, related equipment and storage medium. Background technique [0002] figure 1 shows the processing flow of packets in layer 2, from figure 1 It can be seen that in the related art, the data packet experiences Service Data Adaptation Protocol (SDAP, ServiceDataAdaptationProtocol), Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol), Radio Link Control (RLC, Radio Link Control) and The processing of the four sublayers of the media access control (MAC, Media Access Control) obtains the MAC protocol data unit (PDU, Protocol Data Unit) sent to the air interface. [0003] When multiple low protocol layers are defined under the Internet Protocol (IP, Internet Protocol) layer, a new PDU will be generated every time a low protocol layer passes through, and a PDU header will be correspondingly generated at this t...
