摘要：

作为第一种达到信道容量的高性能编码,极化码是未来6G数据传输的重要候选方案。为此提出了面向6G的极化编码非正交多址接入技术框架。极化编码协作非正交多址接入方案能够满足6G大容量传输需求,极化编码非协作非正交多址接入方案能够提高6G物联网场景的接入可靠性。这些方案表明,极化编码非正交多址接入技术能够满足6G移动通信系统的超高可靠、高频谱效率、大容量的传输需求,具有广阔的应用前景。

Abstract:

As the first type of channel codes which has achieved the channel capacity, polar codes are an important candidate for the 6G data transmission. A polar coded framework of the non-orthogonal multiple access (NOMA) to the 6G system is proposed. In this framework, the scheme for the polar coded coordinated NOMA is investigated to fulfill the requirement of high-capacity transmission of 6G systems. Furthermore, the scheme for the polar coded non-coordinated NOMA can achieve the ultra-high reliable access to the 6G internet scenario. All these schemes indicate that polar coded NOMA techniques can dramatically boost the performance of 6G wireless transmission and has a broad application prospect.

Key words: polar codes, channel polarization, coordinated NOMA, non-coordinated NOMA, polar coded NOMA
