Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 10 in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The embodiment of the application provides an antenna control method, an antenna control device and electronic equipment. The main execution body of the antenna control method may be the antenna control device provided in the embodiment of the present application, or an electronic device integrated with the antenna control device, where the antenna control device may be implemented in a hardware or software manner, and the electronic device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
Referring to fig. 1 to fig. 3, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure, fig. 2 is a first flowchart of an antenna control method according to an embodiment of the present disclosure, and fig. 3 is an application scenario diagram of the antenna control method shown in fig. 2. The antenna control method provided by the embodiment of the present application may be applied to the electronic device 100, and the electronic device 100 may include a plurality of antennas 10, for example, including an antenna 10a, an antenna 10b, and an antenna 10c … …. The antenna control method of the embodiment of the application comprises the following steps:
in 101, when an antenna power back-off event is triggered, obtaining a plurality of power attenuation value combinations G;
when the electronic device 100 detects that the SAR value of the electronic device 100 exceeds the SAR value threshold, the electronic device 100 may trigger an antenna power back-off event indicating that the SAR value of the electronic device 100 exceeds the SAR value threshold.
It is understood that whether the SAR value of the electronic device 100 exceeds the SAR value threshold may be determined by obtaining a total transmission power of the electronic device 100, which may be a sum of transmission powers of the antennas 10 in the operating state within the electronic device 100. For example, when the antennas 10a, 10b, and 10c are in operation, the total transmit power P0 may be the sum of the transmit power P1 of the antenna 10a, the transmit power P2 of the antenna 10b, and the transmit power P3 of the antenna 10 c. When the total transmit power P0 is greater than or equal to the SAR value threshold, an antenna power back-off event is triggered.
After triggering the antenna power back-off event, the electronic device 100 needs to adjust the current transmission power of one or more antennas 10 so that the adjusted total transmission power P0 of the multiple antennas 10 is smaller than the SAR value threshold, so as to release the triggering of the antenna power back-off event. In the related art, the total transmission power P0 is often reduced by adjusting the transmission power of a certain antenna, but when the adjustment amplitude of the antenna is too large, the radiation performance of the antenna is significantly affected, so that the antenna cannot continue to operate.
In the embodiment of the present application, as shown in fig. 3, after the antenna power back-off event is triggered, the electronic device 100 obtains a plurality of power attenuation value combinations G, such as G1, G2, G3, and G4 … …. Each power attenuation value combination G includes a plurality of power attenuation values, e.g., a, b, c, d … …, the number of which is equal to the number of the plurality of antennas 10, and each power attenuation value corresponds to one antenna 10, so that the plurality of antennas 10 correspond to the plurality of power attenuation values one by one.
For example, as shown in fig. 3, the power attenuation value combination G1 includes a plurality of power attenuation values a1, b1, c1, and the like, where the power attenuation value a1 corresponds to the antenna 10a and represents the power attenuation value of the antenna 10 a; a power attenuation value b1 corresponds to antenna 10b and represents the power attenuation value of antenna 10 b; rate attenuation value c1 corresponds to antenna 10c and represents the power attenuation value of antenna 10c, and so on … …. Similarly, a2, a3 and a4 of the power attenuation value combination G2, the power attenuation value combination G3 and the power attenuation value combination G4 represent power attenuation values of the antenna 10a, b2, b3 and b4 represent power attenuation values of the antenna 10b, c2, c3 and c4 represent power attenuation values of the antenna 10c, and so on … ….
It can be understood that, after the plurality of antennas 10 of the electronic device 100 perform the backoff operation according to the corresponding power attenuation value in each power attenuation value combination G, the total transmission power P0 of the plurality of antennas 10 may be reduced, so as to reduce the SAR value of the electronic device 100, thereby releasing the trigger of the antenna power backoff event.
At 102, determining one or more power attenuation value combinations D to be selected from the plurality of power attenuation value combinations G; the sum of the absolute values of the power attenuation values in each candidate power attenuation value combination D is smaller than the sum of the absolute values of the power attenuation values in other power attenuation value combinations T except for one or more candidate power attenuation value combinations D.
It can be understood that, as long as the total transmission power P0 of the multiple antennas 10 of the electronic device 100 is smaller than the SAR value threshold, the electronic device 100 does not trigger an antenna power back-off event, and therefore, when performing power back-off operation on the multiple antennas 10, there are many power attenuation value combinations G, and the embodiment of the present application needs to select a better back-off operation method from among the many power attenuation value combinations G, and the electronic device 100 may determine one or more candidate power attenuation value combinations D from among the multiple power attenuation value combinations G.
It is understood that the sum of the absolute values of the plurality of power attenuation values in the candidate power attenuation value combination D may be smaller than the sum of the absolute values of the plurality of power attenuation values in each other power attenuation value combination T other than the plurality of candidate power attenuation value combinations D.
For example, as shown in fig. 3, when one or more candidate power attenuation value combinations D include power attenuation value combinations G1 and G2, other power attenuation value combinations T than the candidate power attenuation value combinations D may include power attenuation value combinations G3 and G4 … …. The sum of absolute values of the power attenuation value combination G1 ═ Σ x1 (| a1| + | b1| + | c1| + … …); the sum of absolute values of the power attenuation value combination G2 ═ Σ x2 (| a2| + | b2| + | c2| + … …); the sum of absolute values of the power attenuation value combination G3 ═ Σ x3 (| a3| + | b3| + | c3| + … …); the sum of absolute values of the power attenuation value combination G4 Σ x4 (| a4| + | b4| + | c4| + … …), and so on. Wherein Σ x1 is smaller than Σ x3, Σ x4, … …; Σ x2 is also smaller than Σ x3, Σ x4, … ….
It can be understood that, since the sum of the absolute values of the plurality of power attenuation values in each candidate power attenuation value combination D is smaller than the sum of the absolute values of the plurality of power attenuation values in each other power attenuation value combination T except the plurality of candidate power attenuation value combinations D, when the plurality of antennas 10 of the electronic device 100 perform the backoff operation according to the corresponding power attenuation value in the candidate power attenuation value combination D, the power attenuation values of the plurality of antennas 10 are smaller, and the transmission power of the plurality of antennas 10 is adjusted according to the smaller power attenuation value, so that the adjustment amplitude of the transmission power of the plurality of antennas 10 is smaller, and the adjustment of the smaller amplitude of the transmission power has a smaller influence on the radiation performance of the plurality of antennas 10.
In 103, determining an optimal power attenuation value combination Z from one or more candidate power attenuation value combinations D;
at 104, the transmit power of each antenna 10 is adjusted based on the optimum power attenuation value combination Z.
When a candidate power attenuation value combination D is determined from the plurality of power attenuation value combinations G, the candidate power attenuation value combination D may be determined as the optimal power attenuation value combination Z. The electronic device 100 may adjust the transmission power of the multiple antennas 10 corresponding to the power attenuation value according to the multiple power attenuation values in the optimal power attenuation value combination Z, so that the total transmission power P0 of the multiple antennas 10 after adjustment is smaller than the SAR value threshold, thereby releasing the trigger of the antenna power back-off event.
When a plurality of candidate power attenuation value combinations D are determined from the plurality of power attenuation value combinations G, for example, when the power attenuation value combination G1 and the power attenuation value combination G2 are determined, at this time, the electronic device 100 needs to select one of the two sets of power attenuation value combinations as an optimal power attenuation value combination Z, so that the electronic device 100 can adjust the transmission power of each antenna 10 according to the optimal power attenuation value combination Z.
The antenna control method of the embodiment of the application comprises the following steps: when an antenna power backspacing event is triggered, acquiring a plurality of power attenuation numerical value combinations G; determining one or more power attenuation value combinations D to be selected from the plurality of power attenuation value combinations G; determining an optimal power attenuation value combination Z from one or more candidate power attenuation value combinations D; the transmission power of each antenna 10 is adjusted according to the optimum power attenuation value combination Z. Based on this, since the sum of the absolute values of the plurality of power attenuation values in the candidate power attenuation value combination D is smaller than the sum of the absolute values of the plurality of power attenuation values in other power attenuation value combinations T except the one or more candidate power attenuation value combinations D, the power attenuation value of the one or more candidate power attenuation value combinations D is smaller than that of the other power attenuation value combinations T; when the optimal power attenuation value combination Z is determined from the one or more candidate power attenuation value combinations D, and the plurality of antennas 10 of the electronic device 100 perform the backoff operation according to the corresponding power attenuation value in the optimal power attenuation value combination Z, the power attenuation value of the antenna 10 is small, the adjustment range of the transmission power of the antenna 10 is also small, and further, the influence on the radiation performance of the antenna 10 is also small.
In step 101, obtaining a plurality of power attenuation value combinations G may include: and obtaining a power attenuation numerical value combination G according to a power attenuation calculation formula. The power attenuation calculation formula comprises the following formula:
in the above formula, f (x) is the transmission power of a certain antenna 10 after performing the back-off operation; p is the transmission power of the antenna 10 before performing the backoff operation; x is the power attenuation value of the antenna 10.
Referring to fig. 4 in conjunction with the above formula, fig. 4 is a schematic diagram of a variation curve of the transmission power and the power attenuation. As shown in fig. 4, the abscissa of the graph is the power attenuation value x, which is expressed in dB; the ordinate of the graph is the transmitted power f (x) in dBm after a certain antenna 10 has performed a back-off operation. Wherein, the transmitting power P of the antenna 10 before performing the back-off operation is 3 dBm.
As can be seen from fig. 4, f (x) of the transmission power after the antenna 10 performs the backoff operation and the power attenuation value x are not linear variation values, and when the power attenuation value x varies within a certain range, the variation of f (x) of the transmission power after the antenna 10 performs the backoff operation is obvious; however, when the power attenuation value x exceeds a certain range, the change of the transmitting power F (x) tends to be flat, even hardly changed. Therefore, when performing the back-off operation for a plurality of antennas 10, it is necessary to determine the appropriate power attenuation value for each antenna 10, so that the power attenuation value for each antenna 10 is as small as possible and the total attenuated transmission power P0 can still meet the requirement.
The power attenuation values of the antennas 10 in the electronic device 100 can be calculated according to the above formula (1), and a plurality of power attenuation value combinations G can be obtained.
For example, as shown in fig. 3 and 4, assuming that the antenna 10a is adjusted by a power attenuation value a, the antenna 10b is adjusted by a power attenuation value b, and the antenna 10Cc is adjusted by a power attenuation value c, then:
at this time, for example, if the SAR value of the electronic device 100 is smaller than the SAR value threshold K, then:
F(a)+F(b)+F(c)＜K#(2)
since the power attenuation value x of the antenna 10 is generally greater than or equal to-30 dB and less than or equal to 0dB, a, b, and c may be greater than or equal to-30 dB and less than or equal to 0dB, and in combination with this range, the above equation (1) may be solved, and a finite set of solutions is obtained:
(a1，b1，c1)，(a2，b2，c2)，(a3，b3，c3)，(a4，b4，c4)……
it can be understood that each of the above solutions is a power attenuation value combination G, and a plurality of power attenuation value combinations G can be obtained according to the power attenuation calculation formula.
It can be understood that, in the above, the plurality of power attenuation value combinations G are obtained by the power attenuation calculation formula, and in actual use, the plurality of power attenuation value combinations G may also be obtained by calculation according to the power attenuation table. For example, the power attenuation table may change the transmission power of the antenna 10a with the power attenuation value a of the antenna 10a as a variable, and may continue to obtain the transmission power of the antenna 10b or the antenna 10c with a certain value of the power attenuation value a as a fixed quantity and then change the power attenuation value b of the antenna 10b or the power attenuation value c of the antenna 10c as a variable, and so on, may obtain a change table of the power attenuation values of different antennas 10, from which one or more power attenuation value combinations G may be obtained. Again, this is not described in detail.
Referring to fig. 5 and fig. 6, fig. 5 is a second flowchart of an antenna control method according to an embodiment of the present application, and fig. 6 is an application scenario diagram of the antenna control method shown in fig. 5. The antenna control method comprises the following steps:
in 201, when an antenna power back-off event is triggered, a plurality of power attenuation value combinations G are obtained;
in 202, determining a plurality of power attenuation value combinations D to be selected from the plurality of power attenuation value combinations G;
when the electronic device 100 detects that the SAR value of the electronic device 100 exceeds the SAR value threshold, the electronic device 100 may trigger an antenna power backoff event, and at this time, the electronic device 100 may obtain a plurality of power attenuation value combinations G, each power attenuation value combination G includes a plurality of power attenuation values, the number of the power attenuation values is equal to the number of the plurality of antennas 10, and each power attenuation value corresponds to one antenna 10, so that the plurality of antennas 10 correspond to the plurality of power attenuation values one to one. After the plurality of antennas 10 of the electronic device 100 perform the backoff operation according to the corresponding power attenuation value in each power attenuation value combination G, the total transmission power P0 of the plurality of antennas 10 may be reduced, and then the SAR value of the electronic device 100 may be reduced, so that the trigger of the antenna power backoff event may be released.
When power back-off operations are performed on multiple antennas 10, there are many power attenuation value combinations G, and the electronic device 100 may determine one or more candidate power attenuation value combinations D from the multiple power attenuation value combinations G. If the electronic device 100 determines only one candidate power attenuation value combination D, the candidate power attenuation value combination D may be directly determined as the optimal power attenuation value combination Z; when the electronic device 100 determines a plurality of candidate power attenuation value combinations D, it needs to further determine an optimal power attenuation value combination Z.
In 203, calculating an absolute value difference value between the maximum power attenuation value and the minimum power attenuation value in each power attenuation value combination D to be selected to obtain a plurality of difference values;
in 204, determining a to-be-selected power attenuation numerical combination D corresponding to the difference with the smallest absolute value among the plurality of differences as an optimal power attenuation numerical combination Z;
for example, as shown in fig. 6, when the plurality of candidate power attenuation value combinations D includes power attenuation value combinations G1, G2, and G3, an absolute value difference M1 between a maximum power attenuation value and a minimum power attenuation value in the power attenuation value combination G1 needs to be calculated, for example, the absolute value difference M1 may be equal to | a1| - | b1 |; the absolute difference M2 between the maximum power attenuation value and the minimum power attenuation value in the power attenuation value combination G2 needs to be calculated, for example, the absolute difference M2 may be equal to | a2| - | c2 |; the absolute difference M3 between the maximum power attenuation value and the minimum power attenuation value in the power attenuation value combination G3 needs to be calculated, for example, the absolute difference M3 may be equal to | b3| - | c3|, and then a plurality of differences M1, M2, M3, etc. may be obtained.
When a plurality of differences are determined, the absolute values of M1, M2, M3 may be compared, and the candidate power attenuation value combination D corresponding to the difference with the smallest absolute value may be determined as the optimal power attenuation value combination Z, for example, | M1| is smaller than | M2|, | M3|, and the absolute value of M1 is smallest, so the power attenuation value combination G1 corresponding to M1 may be determined as the optimal power attenuation value combination Z.
It can be understood that the absolute value of the absolute value difference between the maximum power attenuation value and the minimum power attenuation value in the optimal power attenuation value combination Z is smaller than the absolute value of the absolute value difference between the maximum power attenuation value and the minimum power attenuation value in the other power attenuation value combinations D to be selected, so that the power attenuation values of the plurality of antennas 10 in the optimal power attenuation value combination Z are not greatly different, and the power back-off amplitudes of the plurality of antennas 10 in the optimal power attenuation value combination Z are closer.
In 205, the transmit power of each antenna 10 is adjusted according to the optimum power attenuation value combination Z.
After determining the optimal power attenuation value combination Z, the electronic device 100 may adjust the transmission power of each antenna 10 according to the optimal power attenuation value combination Z.
In the antenna control method according to the embodiment of the application, when the multiple candidate power attenuation value combinations D are determined, the electronic device 100 may select, as the optimal power attenuation value combination Z, a group of candidate power attenuation value combinations D in the multiple candidate power attenuation value combinations D, in which the absolute value difference between the maximum power attenuation value and the minimum power attenuation value in the candidate power attenuation value combinations D is the minimum, where the difference between the power attenuation values of the multiple antennas 10 in the optimal power attenuation value combination Z is small, so that the back-off attenuation amplitudes of the multiple antennas 10 in the optimal power attenuation value combination Z are not greatly different, and the back-off attenuations of the multiple antennas 10 are relatively close, and thus, the back-off operation has relatively balanced influence on the multiple antennas 10, and the radiation performance of each antenna 10 can be ensured.
Referring to fig. 7 and fig. 8, fig. 7 is a third flowchart illustrating an antenna control method according to an embodiment of the present application, and fig. 8 is an application scenario diagram of the antenna control method shown in fig. 7. The antenna control method comprises the following steps:
in 301, when an antenna power back-off event is triggered, a plurality of power attenuation value combinations G are obtained;
in 302, determining a plurality of power attenuation value combinations D to be selected from the plurality of power attenuation value combinations G;
in 303, calculating an absolute value difference value between the maximum power attenuation value and the minimum power attenuation value in each power attenuation value combination D to be selected to obtain a plurality of difference values;
in 304, determining a plurality of to-be-selected power attenuation value combinations D corresponding to the difference value with the smallest absolute value among the plurality of difference values as preferred power attenuation value combinations Y;
when the difference with the smallest absolute value among the plurality of differences includes a plurality of differences, the electronic device 100 further needs to determine the optimal power attenuation value combination Z from the candidate power attenuation value combination D corresponding to the smallest absolute value difference, and at this time, the candidate power attenuation value combination D corresponding to the smallest absolute value difference may be determined as the preferred power attenuation value combination Y, so that the electronic device 100 determines the optimal power attenuation value combination Z from the preferred power attenuation value combination Y.
For example, as shown in fig. 8, when the plurality of candidate power attenuation value combinations D includes power attenuation value combinations G1, G2, and G3, an absolute value difference M1 between a maximum power attenuation value and a minimum power attenuation value in the power attenuation value combination G1 is | a1| - | b1 |; the absolute value difference M2 between the maximum power attenuation value and the minimum power attenuation value in the power attenuation value combination G2 is | a2| - | c2 |; the absolute difference M3 between the maximum power attenuation value and the minimum power attenuation value in the power attenuation value combination G3 is | b3| - | c3 |. If | M1| M2| < | M3|, then the difference with the smallest absolute value among the plurality of differences includes two M1 and M2, and then the power attenuation value combination G1 and the power attenuation value combination G2 corresponding to M1 and M2 may be determined as the preferred power attenuation value combination Y. In this case, it is also necessary to determine the optimum power attenuation value combination Z from the preferred power attenuation value combination Y.
In 305, according to the current application scenario of the electronic device 100, a target antenna is determined from the plurality of antennas 10;
when the electronic device 100 determines a plurality of candidate power attenuation value combinations D, it further determines an optimal power attenuation value combination Z from the plurality of candidate power attenuation value combinations D. At this time, the electronic device 100 may obtain the current application scenario and determine the target antenna from the plurality of antennas 10 according to the application scenario.
For example, when the electronic device 100 is in a call state, the priority of the call function of the electronic device 100 is significantly higher than other functions of the electronic device 100, such as an internet function, and at this time, the cellular antenna transmitting the cellular signal in the plurality of antennas 10 is significantly more important than other Wi-Fi antennas, NFC antennas, bluetooth antennas, and the like, so the electronic device 100 may determine the cellular antenna as the target antenna.
In 306, it is determined whether the absolute value of the power attenuation value corresponding to the target antenna is smaller than the absolute value of the power attenuation value corresponding to the other antenna 10 in each preferred power attenuation value combination Y;
in 307, a preferred power attenuation value combination Y with a positive judgment result is determined as an optimal power attenuation value combination Z.
After the target antenna is determined, it is necessary to determine whether the absolute value of the power attenuation value corresponding to the target antenna in each preferred power attenuation value combination Y is smaller than the absolute values of the power attenuation values corresponding to the other antennas 10. For example, when the target antenna is the antenna 10a, it is preferable that the power attenuation value combination Y includes a power attenuation value combination G1 and a power attenuation value combination G2, and in this case, it is necessary to determine whether the absolute value | a1| of the power attenuation value corresponding to the antenna 10a in the power attenuation value combination G1 is smaller than the absolute values | b1|, and | c1| … … of the power attenuation values corresponding to the other antennas 10b, 10c, and obtain the determination result. In this case, it is also necessary to determine whether the absolute value | a2| of the power attenuation value corresponding to the antenna 10a in the power attenuation value combination G2 is smaller than the absolute values | b2|, | c2| … … of the power attenuation values corresponding to the other antennas 10b, 10c, and obtain the determination result.
If the power attenuation value combination G1 is judged to be yes, the power attenuation value combination G1 can be judged to be the optimal power attenuation value combination Z; if the power attenuation value combination G2 is judged to be yes, the power attenuation value combination G2 may be judged as the optimal power attenuation value combination Z.
It can be understood that, since different antennas 10 in the electronic device 100 often focus on different communication functions, the case that all the sets of determination results are yes after step 307 hardly occurs. The antenna control method according to the embodiment of the present application can screen out the optimal power attenuation value combination Z after the judgment in step 307.
It can be understood that, in the plurality of preferred power attenuation value combinations Y, the absolute value of the power attenuation value corresponding to the target antenna in the optimal power attenuation value combination Z is smaller than the absolute value of the power attenuation value corresponding to the other antenna 10, so that the back-off attenuation of the target antenna is minimum compared with that of the other antenna 10 in the optimal power attenuation value combination Z, and the influence of the power back-off operation on the target antenna can be reduced to the maximum extent.
At 308, the transmit power of each antenna 10 is adjusted based on the optimum power attenuation value combination Z.
After determining the optimal power attenuation value combination Z, the electronic device 100 may adjust the transmission power of each antenna 10 according to the optimal power attenuation value combination Z.
In the antenna control method according to the embodiment of the application, when the multiple preferred power attenuation value combinations Y are determined, the electronic device 100 may determine a target antenna from the multiple antennas 10 according to a current application scenario, and then may sequentially determine whether an absolute value of a power attenuation value corresponding to the target antenna in each preferred power attenuation value combination Y is smaller than absolute values of power attenuation values corresponding to other antennas 10; and determining the optimal power attenuation value combination Z according to the optimal power attenuation value combination Y which is judged to be the optimal power attenuation value combination Y. Therefore, compared with the absolute value of the power attenuation value of the other antenna 10, the absolute value of the power attenuation value corresponding to the target antenna in the optimal power attenuation value combination Z is the smallest, and the back-off attenuation of the target antenna in the optimal power attenuation value combination Z is the smallest, so that the influence of the power back-off operation on the target antenna can be reduced to the maximum extent.
In step 307, determining whether the absolute value of the power attenuation value corresponding to the target antenna in each preferred power attenuation value combination Y is smaller than the absolute values of the power attenuation values corresponding to the other antennas 10 includes: obtaining a power attenuation weight value of each antenna 10; in each preferred power attenuation value combination Y, it is determined whether the product of the power attenuation weight value corresponding to the target antenna and the absolute value of the power attenuation value is smaller than the product of the power attenuation weight value corresponding to the other antenna 10 and the absolute value of the power attenuation value.
It is understood that the electronic device 100 may also select the optimal power attenuation value combination Z according to the weight value corresponding to each antenna 10. The weight value may be determined comprehensively according to the frequency used by each antenna 10, the current scene of the electronic device 100, the performance of the antenna 10, and the like, where the weight value may reflect the importance of each antenna 10 in the electronic device 100, for example, the importance of the antenna 10 with a larger weight value is high, and when performing a power backoff operation, it is necessary to consider heavily whether the backoff operation affects the performance of the antenna 10; the antenna 10 having a smaller weight value is less important and can appropriately sacrifice its performance when performing the power back-off operation.
After the weight value of each antenna 10 is determined, it may be determined whether the product of the power attenuation weight value corresponding to the target antenna and the absolute value of the power attenuation value in each preferred power attenuation value combination Y is smaller than the product of the power attenuation weight value corresponding to the other antennas 10 and the absolute value of the power attenuation value.
For example, on the basis of the scenario shown in fig. 8, it may be determined whether the absolute value | a1| of the power attenuation value corresponding to the antenna 10a in the power attenuation value combination G1 in the preferred power attenuation value combination Y is smaller than the product q1 × | a1| of the weight value thereof, and is smaller than the products q2 × | b1|, q3 × | c1| … … of the absolute value of the power attenuation value corresponding to the other antennas 10 and the weight value thereof, and the determination result is obtained. In this case, it is also necessary to determine whether the product q1 × | a2| of the absolute value | a2| of the power attenuation value corresponding to the antenna 10a in the power attenuation value combination G2 in the preferred power attenuation value combination Y and the weight value thereof is smaller than the product q2 × | b2|, q3 × | c2| … … of the absolute value of the power attenuation value corresponding to the other antenna 10 and obtain the determination result.
If in the power attenuation value combination G1, q1 × | a1| < q2 × | b1|, q3 × | c1 |; in the power attenuation value combination G2, q1 × a2| > q2 × b2|, q3 × c2|, then the power attenuation value combination G1 may be determined as the optimal power attenuation value combination Z.
According to the antenna control method, the optimal power attenuation numerical combination Z is determined from the optimal power attenuation numerical combination Y according to the weight value of each antenna 10, so that the backspacing attenuation of the optimal power attenuation numerical combination Z is adaptive to the importance degree of the optimal power attenuation numerical combination Z, and the optimal power attenuation numerical combination Z is determined more accurately.
