Abstract: A DMRS transmission method, a network device, and a computer-readable storage medium are provided. The DMRS transmission method includes: configuring a DMRS for a service channel within a mini-slot; mapping at least one antenna port corresponding to the DMRS for the service channel to a time-domain transmission resource and a frequency-domain transmission resource corresponding to a DMRS for a control channel within the mini-slot; and transmitting the DMRS for the service channel on the time-domain transmission resource and the frequency-domain transmission resource.
