Title:
METHOD FOR TRANSMITTING DEMODULATION REFERENCE SIGNAL, NETWORK DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/024711
Kind Code:
A1
Abstract:
Provided are a method for transmitting a demodulation reference signal, a network device, and a computer readable storage medium. The method comprises: configuring a demodulation reference signal (DMRS) for a service channel in a mini-slot; mapping at least one antenna port corresponding to the DMRS of the service channel to a time-domain transmission resource and a frequency-domain transmission resource corresponding to a DMRS for a control channel in the mini-slot; and transmitting the DMRS of the service channel by means of the time-domain transmission resource and the frequency-domain transmission resource.
