Measurement signal sending method, indication information sending method, and device

A method, comprising:

• determining, by a first network device, a sending object of a measurement signal of a first terminal device, wherein the first network device serves the first terminal device;
• when the sending object comprises a second terminal device, determining, by the first network device, first indication information;
• sending the first indication information to the first terminal device, wherein the first indication information instructs the first terminal device to determine a first timing for sending a first measurement signal used by the second terminal device for measurement, and the first network device is different from a second network device serving the second terminal device;
• when the sending object further comprises the first network device, determining, by the first network device, second indication information;
• and
• sending the second indication information to the first terminal device, wherein the second indication information instructs the first terminal device to determine a second timing for sending a second measurement signal used by the first network device for measurement.

A terminal device, wherein the terminal device is a first terminal device, and the terminal device comprises:

• a processor;
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• determining a first timing of a first measurement signal used by a second terminal device for measurement;
• determining a second timing of a second measurement signal used by a first network device for measurement, wherein the first network device serves the first terminal device and is different from a second network device serving the second terminal device;
• and
• a transmitter configured to send the first measurement signal and the second measurement signal according to the first timing and the second timing respectively.
