Abstract
Provided in the present application are a phase noise estimation method and device, the method comprising: a terminal device determines a first correspondence relationship between M demodulation reference signal (DMRS) port groups and N phase tracking reference signal (PTRS) ports within a plurality of time periods; the terminal device receives a plurality of PTRSes transmitted by an access network device by means of the N PTRS ports within the plurality of time periods; the terminal device determines an antenna module corresponding to the PTRSes which are received in each time period according to the first correspondence relationship and a second correspondence relationship between the M DMRS port groups and an antenna module of the terminal device; and the terminal device estimates the phase noise of the antenna module corresponding to the received PTRSes. Since each DMRS port group corresponds to at least one PTRS port in multiple time segments, the terminal device may estimate the phase noise of the antenna module corresponding to the DMRS port group, thereby improving the reliability of data transmission.
