PHASE NOISE ESTIMATION METHOD AND DEVICE

Abstract

The present invention provides a phase noise estimation method and device, and the method comprises the steps that a terminal device determines a first correspondence relation between M DMRS port groups and N PTRS ports in a plurality of time periods; the terminal device receives a plurality of PTRSs that are transmitted by an access network device in the plurality of time periods through the N PTRS ports; the terminal device determines a second correspondence relation between the M DMRS port groups and an antenna module of the terminal device according to the first correspondence relation, and determines the antenna module corresponding to the PTRS received in each time period; the terminal device performs phase noise estimation of the antenna module corresponding to the received PTRS. Since each DMRS port group is corresponding to at least one PTRS port in multiple time periods, the terminal device can perform phase noise estimation of the antenna module corresponding to the DMRS port group, thereby improving the reliability of data transmission.
