Detailed ways

The technical solution of the present disclosure will be described in further detail below with reference to the drawings and embodiments.

A flowchart of some embodiments of the smart surface control method of the present disclosure is shown in FIG. 1 .

In step 120, the smart surface detects the signal power of a predetermined frequency point from the network device. In some embodiments, the network device may determine the transmission power associated with the control requirement according to the control requirement for the reflected beam of the smart surface, and send the signal to be measured at the predetermined frequency point with the determined transmission power. After the signal to be measured is sent, it passes through the attenuation of the transmission path, reaches the smart surface, and is detected by the smart surface. Smart surfaces do not need to have digital baseband processing capabilities, and do not need to perform complex signal demodulation functions, only need to detect their signal power.

In some embodiments, the network device may be a wireless signal transceiving device such as a base station or another access point.

In some embodiments, the predetermined frequency point may be a single frequency point, or may be multiple frequency points.

In step 130, the smart surface determines the target working mode according to the detected signal power, wherein the reflected beam patterns of the smart surface are different in different working modes.

In some embodiments, when the predetermined frequency point is a unique frequency point, the predetermined frequency point may be used as a one-digit identifier. The smart watch determines the power range in which the detected signal power is located, and then determines the target working mode according to the predetermined association relationship between the power range and the working mode of the smart watch.

In some embodiments, power thresholds τ ₁ ˜τ _N may be defined first, where τ ₁ <τ ₂ <...<τ _N , and the thresholds need to be pre-defined by network devices and smart surfaces. Define the power of the received signal detected by the smart surface on this frequency band as R, then the corresponding reflected beam pattern indication is shown in Table 1 below, and N is a positive integer greater than 1:

The above tables require network devices and smart surfaces to be pre-defined.

In some embodiments, the smart surface and the network device can pre-configure the corresponding relationship between the transmit power and the power range parameters corresponding to the target operating mode. For example, the signal transmit power of the target mode of the network device is XdB, from the network device to The signal attenuation between smart surfaces is about YdB, then the power interval of the detection signal power corresponding to the target working mode of the smart surface is set to include (X-Y) dB power intensity, and the interval width is within a predetermined accuracy range.

In some embodiments, the transmission power of the signal is related to the path loss or distance between the network device and the smart surface, the farther the distance or the greater the path loss, the corresponding increase in the transmission power of the signal; the closer the distance or the greater the path loss The smaller the value, the lower the transmission power of the signal, so as to reduce the interference to other users on the live network as much as possible. In some embodiments, the corresponding relationship between the transmit power and the working mode may be determined first, and then the power range may be determined, and the corresponding relationship between the power range and the working mode may be specified.

In other embodiments, multiple predetermined frequency points can be set as multi-digit identifiers, for example, a single predetermined frequency point can support m pattern identifiers, then two predetermined frequency points can support ^m2 pattern identifiers, 3 predetermined frequency points support m ³ mode identifiers... n predetermined frequency points support m ⁿ , where m and n are integers greater than 1. In some embodiments, when the predetermined frequency point is a plurality of frequency points, the smart surface can determine the signal power of the detected signal of each predetermined frequency point in the respective power intervals, and then follow the sequence of predetermined frequency points Arrange the power ranges to obtain the combination of the power ranges; determine the target working mode according to the predetermined association relationship between the combination of the power ranges and the working mode of the smart surface. In this way, the usable range of the identification is expanded, so that more modes can be set, and the accuracy and flexibility of adjustment can be improved. In some embodiments, the predetermined frequency point is a plurality of frequency points (such as two), and the range of each power interval in the combination of power intervals associated with the working mode is related to the control requirements corresponding to the working mode It is determined by the transmission power of each predetermined frequency point of the network, and the signal attenuation parameters between the network equipment and the smart surface.

After the smart surface detects the signals to be measured at multiple predetermined frequency points, it determines the power intervals of the signal powers of the detected signals at each predetermined frequency points, and then arranges the power intervals according to the predetermined frequency point order to obtain all Combination of power intervals at . The target working mode is determined according to the predetermined association relationship between the combination of the power intervals and the working mode of the smart surface.

In some embodiments, if the predetermined frequency points are multi-frequency points (take two frequency points as an example), the smart surface can also determine the target working mode according to the detected signal power in the following manner: according to two different frequency points The signal power detected at the predetermined frequency point determines the signal power difference between the two, and then determines the power difference interval in which the signal power difference is located. The target working mode is determined according to the predetermined correlation between the power difference interval and the working mode of the smart surface.

In some embodiments, power difference thresholds τ ₁ ˜τ _N may be defined first, where τ ₁ <τ ₂ <...<τ _N , and the thresholds need to be pre-defined by network devices and smart surfaces. Furthermore, it is defined that the received signal power detected by the smart surface at frequency point 1 is R ₁ , the signal received power at frequency point 2 is R ₂ , ..., and the signal received power at frequency point N is R _N . Different reflected beam patterns are indicated according to the signal received power difference relationship among R ₁ , R ₂ , . . . , _RN . Taking dual-frequency points as an example, the reflected beam pattern indication is shown in Table 2 below, and N is a positive integer greater than 1:

The above tables require network devices and smart surfaces to be pre-defined.

In some implementations, a group of two predetermined frequency points may be used as a one-digit identifier; by setting multiple groups of predetermined frequency points as a multi-digit identifier, the number of transferable working modes may be extended.

Through such a method, the operation of subtracting signal power at different frequency points can be used to avoid the impact of signal attenuation fluctuations in the transmission path on the detected signal power, thereby improving the accuracy of determining the target working mode.

In step 140, the smart surface adjusts the working parameters corresponding to the target working mode, so as to form a corresponding reflection beam pattern.

Through this method, the power of the signal at a predetermined frequency point can be used to transmit the required mode information of the smart surface, so that the smart surface can adjust its own working parameters according to the signal power, generate a reflected beam pattern in the corresponding working mode, and change the device It is small, low in cost, and easy to implement; and there is no need to demodulate signals in the implementation process, which reduces the consumption of computing resources, reduces the impact on the computing capability of equipment, and improves execution efficiency.
