The technical scheme of the present disclosure is described in further detail below through the accompanying drawings and examples.
A flowchart of some embodiments of the smart surface control method of the present disclosure is shown in fig. 1.
In step 120, the intelligent surface detects signal power from a predetermined frequency point of the network device. In some embodiments, the network device may determine a transmit power associated with the control requirement based on the control requirement for the reflected beam of the smart surface and transmit a signal to be measured at the determined transmit power at a predetermined frequency point. When the signal to be measured is transmitted, the signal reaches the intelligent surface through the attenuation of the transmission path and is detected by the intelligent surface. The intelligent surface does not need to have digital baseband processing capability, does not need to execute complex signal demodulation function, and only needs to detect the signal power.
In some embodiments, the network device may be a wireless signal transceiver device such as a base station or other access point.
In some embodiments, the predetermined frequency point may be a unique frequency point or may be a plurality of frequency points.
In step 130, the smart surface determines a target operating mode based on the detected signal power, wherein the reflected beam pattern of the smart surface is different for different operating modes.
In some embodiments, the predetermined frequency point may be used as a one-digit identifier in the case where the predetermined frequency point is a unique frequency point. The intelligent surface determines a power interval in which the detected signal power is located, and then determines a target working mode according to a preset association relation between the power interval and the working mode of the intelligent surface.
In some embodiments, the power threshold τ may be defined first 1 ～τ N Wherein τ 1 <τ 2 <…<τ N The threshold value requires the network device and the intelligent surface to be predefined.

In some embodiments, the transmit power of the signal is related to the path loss or distance between the network device and the smart surface, with the transmit power of the signal increasing as the distance is greater or the path loss is greater; the closer the distance or the smaller the path loss, the lower the transmission power of the signal, thereby reducing the interference to other users of the current network as much as possible. In some embodiments, the corresponding relationship between the transmitting power and the working mode may be determined first, and then the power interval may be determined, and the corresponding relationship between the power interval and the working mode may be designated.
In other embodiments, a plurality of predetermined frequency points may be set as multi-digit identifiers, for example, a single predetermined frequency point can support m modes, and then two predetermined frequency points can support m 2 Pattern identification, 3 predetermined frequency points support m 3 The mode identifier … … n preset frequency points support m n M and n are integers greater than 1. In some embodiments, under the condition that the predetermined frequency points are a plurality of frequency points, the intelligent surface can determine the power intervals where the signal power of the detected signal of each predetermined frequency point is respectively located, and then arrange the power intervals according to the predetermined frequency point sequence to obtain the combination of the located power intervals; and determining a target working mode according to a preset association relation between the combination of the power intervals and the working mode of the intelligent surface. By means of the method, the usable range of the mark is expanded, so that more modes can be set, and the accuracy and the flexibility of adjustment are improved. In some embodiments, the range of each power interval in the combination of power intervals associated with the operation mode is determined according to the transmission power of each predetermined frequency point associated with the control requirement corresponding to the operation mode and the signal attenuation parameter between the network device and the intelligent surface.
After detecting signals to be measured of a plurality of preset frequency points, the intelligent surface determines power intervals in which the signal power of the detected signals of each preset frequency point is respectively located, and further arranges the power intervals according to a preset frequency point sequence to obtain combinations of the power intervals. And determining a target working mode according to a preset association relation between the combination of the power intervals and the working mode of the intelligent surface.
In some embodiments, if the predetermined frequency point is a multi-frequency point (taking two frequency points as an example), the intelligent surface may further determine the target working mode according to the detected signal power by: and determining the signal power difference of the two signal power points according to the signal power detected at the two different preset frequency points, and further determining the power difference section where the signal power difference is located. And determining a target working mode according to a preset association relation between the power difference interval and the working mode of the intelligent surface.
In some embodiments, the transmit power of the signal is related to the path loss or distance between the network device and the smart surface, with the transmit power of the signal increasing as the distance is greater or the path loss is greater; the closer the distance or the smaller the path loss, the lower the transmission power of the signal, thereby reducing the interference to other users of the current network as much as possible. In some embodiments, the corresponding relationship between the transmitting power and the working mode may be determined first, and then the power interval may be determined, and the corresponding relationship between the power interval and the working mode may be designated.
In some embodiments, a power difference threshold τ may be defined first 1 ～τ N Wherein τ 1 <τ 2 <…<τ N The threshold value requires the network device and the intelligent surface to be predefined. Further define the signal receiving power on the frequency point 1 detected by the intelligent surface as R 1 The signal receiving power on the frequency point 2 is R 2 … the signal receiving power at the frequency point N is R N . According to R 1 ，R 2 ，…，R N The signal received power difference relationship between them indicates the different reflected beam patterns. For the two-tone example, the reflected beam pattern indication is shown in Table 2 below, where N is a positive integer greater than 1:
table 2 pattern correspondence
| R range | Mode of operation |
| R 2 -R 1 ≤τ 1 | Number 0 reflected beam pattern |
| τ 1 <R 2 -R 1 ≤τ 2 | Reflection beam pattern number 1 |
| τ 2 <R 2 -R 1 ≤τ 3 | Number 2 reflected beam pattern |
| … | … |
| τ N-1 <R 2 -R 1 ≤τ N | N-1 reflection beam pattern |
| τ N <R 2 -R 1 | N number reflection beam pattern |
The above-described tables require network devices and intelligent surfaces to be predefined.
In some implementations, two predetermined frequency points can be used as a group to be used as a one-digit identification; and by setting a plurality of groups of preset frequency points as multi-bit identification, the number of the working modes which can be transferred is expanded.
