1. A resource configuration method, wherein the method comprises:
receiving two or more groups of resource configuration information of a demodulation reference signal (DMRS), wherein the resource configuration information is information for configuring DMRS resources used to transmit the DMRS and the DMRS is used for demodulating a physical data channel; and
determining, based on the two or more groups of resource configuration information, a DMRS resource configured by each group of resource configuration information,
wherein the resource configuration information comprises at least one of the following: a quantity of front-loaded DMRSs, a position of a front-loaded DMRS, a position of an additional DMRS, a DMRS type, or a quantity of additional DMRSs;
in the two or more groups of resource configuration information, a DMRS resource configured by a first group of resource configuration information does not intersect with a physical data channel resource corresponding to a second group of resource configuration information; and
a physical data channel corresponding to the physical data channel resource is demodulated by using a DMRS transmitted on a second DMRS resource configured by the second group of resource configuration information;
wherein the second DMRS resource is selected for demodulating the physical data channel based on a priority rule and the priority rule is based on whether signaling for configuring the resource configuration information is primary or secondary signaling.
