1. An uplink transmission resource indication method, applied to a first network device, wherein the method comprises:
determining a first reference signal RS resource of a second network device in a time-frequency resource, wherein the time-frequency resource comprises a plurality of time units in a time domain, the first RS resource is located in a first time unit of the plurality of time units;
sending first configuration information to a user equipment, wherein the first configuration information is for determining an uplink transmission resource in the time-frequency resource, and the uplink transmission resource does not overlap the first RS resource; and
sending second configuration information to the user equipment, wherein the second configuration information indicates a first location offset of an uplink demodulation reference signal DMRS, wherein a time domain symbol occupied by the uplink DMRS after the uplink DMRS is shifted by the first location offset is different from a time domain symbol occupied by the first RS resource.
