Abstract
本公开提出了一种上行相位跟踪参考信号PT‑RS的增强方法、装置及通信设备，涉及无线通信技术领域。其中，方法包括：通过网络侧设备向UE发送指示消息，其中，所述指示消息包括用于指示多个发送与接收点TRP分别对应的多个PT‑RS指示信息，所述PT‑RS指示信息用于表示面向对应TRP发送的，且指示与对应PT‑RS端口相关联的解调参考信号DMRS端口。由于向UE发送的指示消息中包括了面向对应TRP发送的多个PT‑RS指示信息，且各PT‑RS指示信息指示与对应PT‑RS端口相关联的DMRS端口，解决了PT‑RS在基于多TRP传输时无法针对不同的CPE噪声源与DMRS端口关联的问题，有利于提高系统性能。
