1. A method for transmitting an uplink signal, comprising:
receiving, by a terminal device, resource configuration information carried by a Radio Resource Control (RRC) message, wherein the resource configuration information is used to indicate a plurality of resources configured for zero-power Demodulation Reference Signal (DMRS);
receiving, by the terminal device, activation information carried by Downlink Control Information (DCI), wherein the activation information is used to indicate:
whether to enable the zero-power DMRS; and
selecting a resource occupied by the enabled zero-power DMRS in the plurality of resources configured for the zero-power DMRS indicated by the resource configuration information; and
determining, by the terminal device, the resource occupied by the zero-power DMRS based on the resource configuration information and the activation information;
wherein the resource occupied by the zero-power DMRS is not used for sending uplink data, and the resource occupied by the zero-power DMRS is not used for sending non-zero-power DMRS.
