1. A method for a terminal device to determine demodulation reference signal (DMRS), the method comprising:
obtaining a DMRS configuration and a corresponding signature assigned by a network side node;
constructing a DMRS according to the DMRS configuration; and
mapping the DMRS to a physical channel assigned to the terminal device;
wherein the signature indicates a processing configuration for the physical channel, and wherein an identifier number IDS of the signature is determined based on at least one of: an identifier number n of a DMRS port, an identifier number IDGP of a generation parameter of a DMRS sequence, and a value of the generation parameter.
