1. A positioning method for a transmitting device, comprising:
determining 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;
transmitting a pilot signal to the meta-surface by a transmitting device, wherein the transmitting device is located in the target area;
sending 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
determining a signal measurement result corresponding to the preset direction, and positioning 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.
