摘要

5G 的业务特性及能力要求为新空口（new radio，NR）设计更加高效的新型信道编码方案，极化码（Polar码）因具备优异的性能已被确定为5G增强移动宽带（enhancedmobile broadband，eMBB）场景控制信道的编码方案。在对5G及Polar码进行概述的基础上，详细阐述面向5G NR的Polar码标准化工作主要研究内容，包括码构建、序列设计、速率匹配及信道交织等。继而针对第三代合作伙伴计划（3rd Generation Partnership Project，3GPP）各成员机构在无线接入网层一（Radio Access Network Layer 1，RAN1）标准化工作组提出的Polar码编码方案进行分析和对比，并在此基础上对Polar码标准化相关研究进展进行总结。

Abstract

Amore efficient new channel coding scheme was required for NRby the service features and capability indices of 5G.Due to its excellent performance

Polar code was specified as the control channel coding scheme for 5G enhancedmobile broadband(eMBB)scenario.An overview of Polar code was presented and themain existing research issues of the standardization for new radio(NR)technology oriented Polar code

including code construction

sequence design

rate-matching and channel interleaving

etc

were elaborated.Then some specific analysis and comparisons of the Polar code schemes which were proposed by 3GPPmember institutes in RAN1 conferences recently were presented.Finally

a summary of the standardization works of Polar code was given on the basis of the above discussions.
