Abstract
本公开提出一种信息传输方法、装置、终端设备、基站及存储介质，属于通信技术领域。方法包括：获取与上行PT‑RS发送相关联的目标解调参考信号DMRS端口，其中，所述基站配置的目标DMRS端口用于PUSCH第一个传输时机的PT‑RS传输；确定后续每个传输时机用于发送PT‑RS的对应的目标DMRS端口；其中，一个PT‑RS端口在每个传输时机对应一个目标DMRS端口，所述目标DMRS端口包括于对应的所述PT‑RS端口所关联的DMRS端口组中，且相邻的两个所述传输时机的对应的目标DMRS端口不同；在每个传输时机上PT‑RS端口映射到对应的目标DMRS端口，用以传输所述PT‑RS。本公开提供的方法中，PT‑RS传输精度较高，相位噪声估计的准确度较高。
