Abstract: A method for transmitting a DMRS of a physical broadcast channel, a network device and a terminal for performing the method are provided. The method includes: configuring a demodulation reference signal DMRS sequence of a new radio physical broadcast channel NR-PBCH, where the DMRS sequence is configured to indicate a position relation between a synchronization signal block to which the NR-PBCH belongs and a system frame where the SS block is located; and transmitting the DMRS sequence of the NR-PBCH to a terminal. The configuring the DMRS sequence of the NR-PBCH includes: configuring phase rotation information of the DMRS sequence of the NR-PBCH. The position relation between the SS block to which the NR-PBCH belong and the system frame where the SS block is located includes: the SS block being located in a first or last 5 ms of the system frame where the SS block is located.
