Abstract

本申请提供一种DMRS传输方法及装置。该方法包括：UE根据预设的CSF跳变步长、随机变量以及根据预设的规则确定的CSF确定当前子帧的DMRS对应的CSF，其中，预设的CSF跳变步长是4，随机变量根据预设的随机序列生成，根据当前子帧的DMRS对应的CSF映射的CS、OCC以及子载波集合，向基站发送DMRS，实现了在根据当前子帧的DMRS对应的CSF映射的CS、OCC及子载波集合发送DMRS时，仍然能够保持复用UE的DMRS之间的正交，以使基站在接收到不同的UE的DMRS时能正确区分，使得基站解调PUSCH和PUCCH时性能提高，从而提高了信道估计的准确性，进而，提高了UE的上行吞吐量。
