In some embodiments, the corresponding relationship between the transmission power and the operation mode may be determined first, and then the power interval may be determined, and the corresponding relationship between the power interval and the operation mode may be specified.
In some embodiments, a power difference threshold may be defined firstτ1～τNWherein, τ1<τ2<…<τNThe threshold value needs to be predefined by the network device and the intelligent surface. And then defining the signal receiving power on the frequency point 1 detected by the intelligent surface as R1The signal reception power at frequency point 2 is R2…, the signal reception power at frequency point N is RN. According to R1，R2，…，RNThe signal received power difference relationship between indicates the different reflected beam patterns. In the dual-band spot example, the reflected beam pattern indications are shown in table 2 below, where N is a positive integer greater than 1:

| τ1<R2-R1≤τ2 | Reflected beam pattern number 1 |
| τ2<R2-R1≤τ3 | Reflected beam pattern number 2 |
| … | … |
| τN-1<R2-R1≤τN | N-1 reflected beam pattern |
| τN<R2-R1 | Number N reflected beam pattern |
