Abstract

METHOD AND DEVICE FOR TRANSMITTING UPLINK DEMODULATION REFERENCE SIGNAL The present application provides a method and device for transmitting an uplink demodulation reference signal. The method comprises: a terminal device receiving first demodulation reference signal(DMRS) configuration information sent by a network device, the first DMRS configuration information being used to indicate a type of a DMRS sequence; the terminal device receiving second DMRS configuration information sent by the network device, the second DMRS configuration information being used to indicate at least one of the following configuration parameters: DMRS antenna port configuration, DMRS physical resource configuration, and DMRS sequence configuration; the terminal device determining, according to the first DMRS configuration information, a configuration parameter indicated by the second DMRS configuration information; determining, according to the configuration parameter indicated by the second DMRS configuration information, a transmission parameter of the DMRS; and transmitting the DMRS according to the transmission parameter. The method for transmitting an uplink demodulation reference signal of the present application enables the terminal device to be compatible with multiple types of DRMS sequences. (FIG. 1)
