Abstract
The present disclosure relates to a method for a terminal device to determine demodulation reference signal (DMRS), comprising: obtaining (211) a DMRS configuration and a corresponding signature assigned by a network side node; constructing (212) a DMRS according to the DMRS configuration; mapping (213) the DMRS to a physical channel assigned to the terminal device. The signature indicates a processing configuration for the physical channel. In the embodiments of the present disclosure, the signature, and DMRS configuration may be configured correspondingly, to obtain low-crosstalk DMRS signals for different terminal devices, thus, the number of the supported terminal devices may be improved.
