Positioning method, device and system for transmitting device, and storage medium and electronic device

A positioning device for a transmitting device, comprising a memory storing instructions and a processor in communication with the memory, wherein the processor is configured to execute the instructions to:

• determine control information by a receiving device, wherein the control information comprises temporal information and control direction information;
• the control direction information is used for instructing a meta-surface control unit to adjust a reflection coefficient of a meta-surface to a target reflection coefficient corresponding to a preset direction, so that a beam in a direction from the receiving device to the meta-surface forms on the meta-surface a reflected beam in the preset direction;
• the preset direction is a direction indicated by preset direction information corresponding to a target time period, and the preset direction points to a target area:
• the temporal information comprises the target time period;
• and the control direction information comprises the preset direction information;
• transmit a pilot signal to the meta-surface by a transmitting device, wherein the transmitting device is located in the target area;
• send the control information to the meta-surface control unit by the receiving device, wherein the control information is used for instructing the meta-surface control unit to adjust the reflection coefficient of the meta-surface to the target reflection coefficient corresponding to the preset direction within the target time period;
• and
• determine a signal measurement result corresponding to the preset direction, and position the transmitting device according to the preset direction and the signal measurement result, wherein the signal measurement result is a measurement result obtained by the receiving device measuring a received target pilot signal;
• the target pilot signal is received by the receiving device after reflected by the meta-surface whose reflection coefficient is adjusted to the target reflection coefficient;
• and the pilot signal transmitted by the transmitting device comprises the target pilot signal.
