摘　　要：6G预期会承载虚拟现实(VR)、生成式人工智能(GenAI)等需要大数据量、沉浸式体验的业务。作为一个全球统一的移动通信标准,6G将会有超过十年的商用周期,期间会出现一些目前还没有问世的新兴应用,将对极致连接有更高的需求。根据ITU的建议,6G峰值数据速率需要在5G信道编码的基础上至少有10到20倍的提升,这就需要在6G提出新的编译码方案,或基于现有编码方案进行演进。为此,探讨了沉浸式通信对信道编译码的需求,阐述了对于未来峰值速率场景,需要进一步降低译码复杂度,降低功耗。然后,基于现有Polar码和LDPC码方案给出了比较,揭示Polar码在低复杂度区间具有更优的纠错性能。进一步提出了增强的高吞吐Polar编译码方案,并对它们的译码效率进行了理论分析。6G is expected to carry data-intensive and immersive services like virtual reality(VR)and generative artificial intelligence(GenAI).As a globally unified mobile communication standard,6G will have a commercial cycle of exceeding 10 years,during which some emerging applications that have not yet been launched will appear,with higher requirements for extreme connectivity.As per ITU recommendations,6G peak data rate should be 10-20 times higher than those of 5G channel coding,which requires a novel coding scheme for 6G or an evolution based on the existing coding scheme.To this end,the requirements of immersive communications for channel coding are discussed,and for future peak rate scenarios,it is necessary to further reduce decoding complexity and power consumption.A comparison evaluation of Polar and LDPC codes reveals the superior error correction performance of Polar codes in low-complexity regimes.Based on this observation,the enhanced highthroughput Polar coding schemes are proposed and the theoretical analysis of their decoding efficiency is provided.
