The method includes: determining, by a communications device, a current mode of a resource scheduling unit, where the current mode is a frequency hopping mode or an aggregation mode, and performing, by the communications device, DMRS mapping or demapping by using a DMRS pattern corresponding to the current mode, where a location of a symbol occupied by a DMRS in the DMRS pattern corresponding to the current mode is different from a location of a symbol occupied by a DMRS in a preset DMRS pattern. In embodiments of this application, a location of a symbol occupied by a DMRS can be flexibly selected depending on different modes. Therefore, requirements of the different modes can be satisfied in the embodiments of this application, thereby improving network performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DMRS transmission method and communications device","description":"This application provides a Demodulation Reference Signal (DMRS) transmission method and a communications device.
