Abstract  Abstract

The method comprises the step that terminal equipment determines a first corresponding relation between M DMRS port groups and N PTRS ports in a plurality of time periods. The terminal equipment receives a plurality of PTRS sent by the access network equipment through the N PTRS ports in a plurality of time periods. And the terminal equipment determines the antenna module corresponding to the PTRS received in each time period according to the first corresponding relation and the second corresponding relation between the M DMRS port groups and the antenna module of the terminal equipment. And the terminal equipment carries out phase noise estimation on the antenna module corresponding to the received PTRS. Because each DMRS port group corresponds to at least one PTRS port in a plurality of time periods, the terminal equipment can perform phase noise estimation on the antenna module corresponding to the DMRS port group, and further the reliability of data transmission can be improved.
