Reference signal sending method and reference signal sending apparatus

A reference signal sending apparatus comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for being executed by the processor, the programming instructions, when executed, instruct the processor to:
• determine a first reference signal and a first code resource, wherein the first code resource is orthogonal to a second code resource, the second code resource is used to transmit a second reference signal, the first reference signal is a reference signal of a first type, the second reference signal is a reference signal of a second type, and the first type is different from the second type;
• and
• send the first reference signal by using the first code resource, wherein the first reference signal is carried by at least one first time-frequency resource group, wherein a value of a quantity of resource elements (REs) occupied by each of the at least one first time-frequency resource group is the same as a value of a length of the first code resource, and the first reference signal and the second reference signal are multiplexed on a time-frequency resource occupied by the at least one first time-frequency resource group, based on the first code resource and the second code resource.
