The method includes: determining a number of bits of a PTRS-DMRS association in a DCI to be transmitted according to a number of SRS resources, a number of PT-RS ports, and a maximum uplink rank number supported by a UE; and transmitting the DCI to the UE, wherein the DCI carries indication bits which have a same number with the bits and apply to indicate an association relationship between the PT-RS ports and the DMRS ports. The present disclosure realizes indication of association relationships between PT-RS ports and DMRS ports in the event of multiple PT-RS ports."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for indicating PT-RS port for non-codebook-based uplink PUSCH transmission, and base station","description":"The present disclosure provides a method and a device for indicating PT-RS port for non-codebook-based uplink PUSCH transmission, and a base station.
