This paper proposed three HARQ-ACK/NAK bit coding algorithm in the case of the number of HARQ-ACK/NAK bits was 1 or 2 bit only in the PUSCH channel. The idea of this three HARQ-ACK/NAK information coding algorithm came from repeat code,linear block code, Hamming distance, Euclidean distance. Comparison the simulation results of this three algorithms, this paper selected an optimal coding method that could satisfy high requirements of BER in any modulate method. This algorithm had been applied to the LTE-TDD wireless integrated test instrument.%针对LTE物理上行共享信道(PUSCH),且HARQ-ACK/NAK信息比特数在1或2 bit时,提出三种HARQ-ACK/NAK信息编码算法.这三种算法的思想来源于重复码、线性分组码、汉明距离、欧式距离.比较三种算法的仿真结果,选择了一种在任何调制方式下都可以达到很高BER要求的最优编码算法,该算法已应用于LTE-TDD无线综合测试仪表的开发中.
