One important design goal of 6G networks is adapting to complex heterogeneous scenarios and providing a stable and reliable transmission channel for specific applications such as vehicular communication. To achieve this, scholars attempt to use heterogeneous wireless networks around a vehicle to improve the reliability of 6G network transmission through multipath transmission schemes and network coding schemes. However, the wireless networks around the vehicle may experience burst consecutive loss due to wireless channel fluctuations. Currently, the classic multipath transmission schemes and network coding schemes may not be able to deal with such packet loss in time, which affects the reliability of transmission.

In this paper, we propose a skip network coding (SNC) multipath transmission scheme that draws on the idea of interleaving, which groups and encodes discrete packets that meet the interleaving distance. SNC can decrease burst consecutive loss without packet reordering issues to improve transmission performance. In addition, we provide the algorithmic implementation details of SNC. Finally, we design a vehicular communication multipath transmission simulation system based on network simulation 3 (NS-3) and verify that the universality of SNC multipath transmission schemes in mobile scenarios is superior to current multipath transmission schemes.

通过跳过网络编码提高6G车载通信的可靠性

6G网络的一个重要设计目标是适应复杂的异构场景,为车载通信等特定应用提供稳定可靠的传输通道。为此,学者们尝试在车辆周围使用异构无线网络,通过多径传输方案和网络编码方案来提高6G网络传输的可靠性。然而,由于无线信道波动,车辆周围的无线网络可能会出现突发连续丢失。目前,经典的多径传输方案和网络编码方案可能无法及时处理此类丢包问题,影响传输的可靠性。

在本文中,我们提出了一种利用交织思想的跳过网络编码(SNC)多径传输方案,该方案对满足交织距离的离散数据包进行分组和编码。SNC 可以减少突发连续丢失,而不会出现数据包重新排序问题,从而提高传输性能。此外,我们还提供了 SNC 的算法实现细节。最后,我们设计了一个基于网络仿真3(NS-3)的车载通信多径传输仿真系统,验证了SNC多径传输方案在移动场景下的通用性优于当前的多径传输方案。
