Example 1

The following describes a wireless signal transmission method provided in Embodiment 1 of the present application. The wireless signal transmission method is applied to a terminal device, please refer to FIG. 1, and the wireless signal transmission method provided in Embodiment 1 of the present application includes:

In step S101, according to the current transmission power of the terminal device, a first wireless signal is transmitted;

In the embodiment of the present application, the first wireless signal may be a wireless signal with a fixed duration, for example, a wireless signal with a fixed duration of 5 ms; or, the first wireless signal may also be a wireless signal with a variable duration. The application is not limited.

In the technical solution provided by the embodiment of the present application, the current transmit power of the terminal device needs to be updated according to the subsequent steps of the embodiment of the present application. However, the initial transmission power of the terminal device can be set by the user, or can also be determined according to the connection rate of the terminal device. For details, refer to the description of Embodiment 2 of the present application.

In step S102, obtain the bit error rate of the first wireless signal;

After transmitting the first wireless signal, the bit error rate of the transmitted first wireless signal may be obtained; or, it may be first determined whether the current transmission power is greater than a preset transmission power Time, the bit error rate of the first wireless signal is acquired, so that the transmission power is adjusted according to the bit error rate of the terminal device only when the transmit power of the terminal device is large.

In the embodiment of the present application, the method for acquiring the bit error rate may be: determining the channel environment of the first wireless signal (for example, determining whether the transmission channel of the first wireless signal includes buildings, the density of buildings, Whether it contains trees, the density of trees, etc.), and then, the bit error rate of the first wireless signal is determined by the determined channel environment and the current transmission power of the terminal device.

In the embodiment of the present application, the method for obtaining the bit error rate may also be: first, return the wireless signal received by the first wireless signal receiver to the terminal device, and then, the terminal device returns by comparing the receiver And the first wireless signal to determine the bit error rate of the first wireless signal (to ensure that the receiver can return the received wireless signal to the terminal device without errors, the receiver can use a large Power transmission of the received wireless signal to the terminal device). For example, assuming that the above terminal device is used for communication connection with an access point (Access Point, AP), the above step S101 may include: according to the current transmission power of the above terminal device, transmitting a first wireless signal to the AP to indicate the The AP performs the operation of returning the currently received wireless signal sent by the terminal device to the terminal device; accordingly, this step S102 may include: receiving the second wireless signal returned by the AP, by comparing the first wireless signal and the above The second wireless signal determines the bit error rate of the first wireless signal.

In addition, before receiving the second wireless signal returned by the AP, the wireless signal sending method provided by the embodiment of the present application may further include the following step A:

Step A: After sending the first wireless signal to the AP, determine whether the second wireless signal returned by the AP is received within a preset time period (for example, within 1 ms after sending the first wireless signal) ;

Correspondingly, this step S102 (ie: receiving the second wireless signal returned by the AP, and determining the bit error rate of the first wireless signal by comparing the first wireless signal and the second wireless signal) includes: When the second wireless signal returned by the AP is received within a set time period, the bit error rate of the first wireless signal is determined by comparing the first wireless signal and the second wireless signal.

In addition, after the above step A, the wireless signal sending method according to the first embodiment of the present application may further include: if the second wireless signal returned by the AP is not received within the preset time period, an output is used to prompt the user Prompt information for communicating with the AP; or, may also include the following step B:

Step B: If the second wireless signal returned by the AP is not received within the preset time period, increase the size of the current transmission power and return to step S101 (ie: according to the current transmission power of the terminal device , Transmitting a first wireless signal to the AP to instruct the AP to perform the operation of returning the currently received wireless signal sent by the terminal device to the terminal device).

In step S103, it is determined whether the bit error rate is less than a preset threshold, where the preset threshold is less than the maximum bit error rate allowed when the terminal device transmits the first wireless signal, and if so, step S104 is executed, otherwise, Go to step S105;

After acquiring the bit error rate of the transmitted first wireless signal, it is necessary to first determine whether the bit error rate is less than a preset threshold, where the preset threshold is less than the terminal device can tolerate when sending the first wireless signal The maximum bit error rate, for example, if the above maximum bit error rate is 0.07, the preset threshold may be 0.03.

In step S104, the above-mentioned current transmission power is reduced by a first preset value;

If the bit error rate of the transmitted first wireless signal is less than the preset threshold, the current transmission power of the terminal device is reduced. The unit of the first preset value may be decibel, for example, the first preset value may be 1 dB; or, the unit of the first preset value may also be watt, for example, the first preset value may be It is 0.3mW, and the form of the above first preset value is not limited in this application.

In step S105, determine whether the error rate is greater than the maximum error rate;

If the bit error rate of the transmitted first wireless signal is not less than the preset threshold, it is further determined whether the bit error rate is greater than the maximum allowable bit error rate when the terminal device sends the first wireless signal.

In step S106, if the error rate is greater than the maximum error rate, the current transmission power is increased by a second preset value, where the first preset value is less than the second preset value;

Same as the above first preset value, the unit of the second preset value may be decibel, for example, the second preset value may be 5dB; or, the unit of the second preset value may also be watt, for example, The second preset value may be 0.5 mW, and the form of the above second preset value is not limited in this application.

In the embodiment of the present application, the first preset value is smaller than the second preset value, so that when the bit error rate of the terminal device is small, the correction rate of the bit error rate is relatively slow, and when the terminal device When the bit error rate is greater than the maximum allowable bit error rate, the correction rate of the bit error rate is relatively fast, therefore, it can be ensured that the bit error rate of the terminal device can be maintained at a relatively small value for a long time, Thereby ensuring the wireless communication performance of the terminal equipment.

In addition, after the above step S105, the wireless signal transmission method in the embodiment of the present application may further include: if the above bit error rate is less than or equal to the above maximum bit error rate, the current transmit power may be reduced (please note to those skilled in the art, At this time, the decrease value of the current transmit power is not necessarily the above-mentioned first preset value), and the increase of the current transmit power (please note to those skilled in the art, at this time, the increase value of the current transmit power is not necessarily the above-mentioned second (Default value) or keep the current transmit power unchanged, which is not limited in this application.

In order to more clearly understand the technical solution provided in Embodiment 1 of the present application, the following description will be made using FIG. 2.

As shown in FIG. 2, in the two-dimensional coordinate system composed of "time T-bit error rate PER", assuming that the corresponding point in the two-dimensional coordinate system is A at time T1, from this figure 2 can be It can be seen that the bit error rate at time T1 is less than the preset threshold. According to the technical solution of the embodiment of the present application, it is necessary to reduce the current transmit power of the terminal device by the first preset value. Those skilled in the art are aware that reducing the transmit power, It will increase the bit error rate. Therefore, in order to avoid the sudden increase of the bit error rate of the terminal device and suddenly reduce the wireless communication performance of the terminal device (the sudden decrease in wireless communication performance will affect the user experience), the terminal can be reduced as slowly as possible The current transmit power of the device, that is, the first preset value may be a small value, to ensure that the bit error rate of the terminal device rises slowly, as shown in FIG. 2, from T1 to T2, and from T2 to T3 The bit error rate at the moment is slowly rising.

Assuming that at time T3, the bit error rate is greater than the preset threshold, in the embodiment of the present application, it is necessary to further determine whether the bit error rate at T3 is greater than the maximum allowable bit error rate, as shown in FIG. 2, If the bit error rate at the time T3 is less than the maximum bit error rate, in the embodiment of the present application, at the time T3, the current transmission power may be reduced, or the current transmission power may be increased, or the current transmission power may also be kept unchanged, assuming Keep the current transmit power constant at time T3 (skilled persons in the art should know that, as time goes by, even if the transmit power of the terminal device remains unchanged, however, due to the continuous changes in the external environment, the bit error rate may fluctuate. As shown in Figure 2, the bit error rate at time T4 is slightly greater than that at time T3).

Due to the influence of the external environment, even if the transmission power of the terminal device at T3-T5 remains unchanged, the bit error rate will fluctuate, assuming that at T6, the bit error rate fluctuates to less than the preset value due to changes in the external environment Threshold value, according to the technical solution of the present application, the transmission power of the terminal device will be further reduced at T6, thereby increasing the bit error rate of the terminal device. As shown in FIG. 2, at T7, the bit error rate increases and is at Between the preset threshold and the aforementioned maximum bit error rate, therefore, at time T7, the current transmit power of the terminal device can be kept unchanged.

Due to the impact of the external environment, assuming that the bit error rate fluctuates greatly at T8, and the bit error rate at T8 is greater than the maximum allowable bit error rate, according to the technical solution of this application, the current transmit power of the terminal device will be used. Increase the second preset value, wherein, in the embodiment of the present application, the second preset value may be a larger value, so that the bit error rate of the terminal device drops rapidly. In the embodiment of the present application, the second preset value may be a value determined according to the current transmit power, so that after the second preset value is increased, the current transmit power of the terminal device directly falls to one of the preset thresholds Within, that is, as shown in FIG. 2, at time T9, the bit error rate of the terminal device is less than the preset threshold.

It can be drawn from FIG. 2 that when the technical solution of Embodiment 1 of the present application satisfies the following conditions, the bit error rate of the terminal device can be caused to fluctuate around a preset threshold:

First, the first preset value is a smaller value (for example, the first preset value is less than the first preset decibel value, where the first preset decibel value may be 1 dB);

Second, the second preset value is a larger value (for example, the second preset value is greater than the second preset decibel value, wherein the second preset decibel value is greater than or far greater than the first preset value (Set the decibel value); or, the second preset value may be a value calculated according to the current transmit power, so that the current transmit power can directly fall within the preset threshold after increasing the second preset value;

Third, when the bit error rate is between the preset threshold and the maximum allowable bit error rate, the current transmission power is maintained unchanged.

Those skilled in the art should note that when the bit error rate of the terminal device fluctuates around the preset threshold, the remaining conditions other than the above three conditions may also be satisfied. Since the preset threshold is less than the maximum allowable bit error rate, making the bit error rate of the terminal device fluctuate around the preset threshold can ensure the wireless communication performance of the terminal device, in addition, because the preset threshold is not a very A small value, therefore, the transmission power of the terminal device can be reduced to a certain extent, and the wireless transmission power of the terminal device can be further reduced by increasing the size of the preset threshold.

Generally, when the terminal device sends a wireless signal, in order to ensure the performance of wireless communication, the power of the transmitted wireless signal is often relatively large, and the bit error rate is also very low. In the first embodiment of the present application, when the transmitted wireless signal When the bit error rate is small (that is, when it is less than the preset threshold), the current transmit power is reduced by the first preset value. Therefore, the technical solution provided in Embodiment 1 of the present application can be compared with the traditional wireless signal transmission method. To a certain extent, the power consumption of the terminal device when transmitting wireless signals is reduced. In addition, in the first embodiment of the present application, when the bit error rate of the transmitted wireless signal is greater than the allowable maximum bit error rate, the current transmit power will be increased by the second preset value to reduce the bit error rate. The technical solution provided by the application can also guarantee the wireless communication performance of the terminal device. Furthermore, in the technical solution provided by the present application, since the first preset value is less than the second preset value, it can make the correction speed of the bit error rate slower when the bit error rate of the terminal device is small When the bit error rate of the terminal device is greater than the maximum allowable bit error rate, the correction rate of the bit error rate is relatively fast. Therefore, in the technical solution provided in Embodiment 1 of the present application, the overall The bit error rate is maintained at a relatively small value for a long time, so it can further ensure the wireless communication performance of the terminal device.

In order to ensure the wireless communication performance of the terminal device, the adjustment of the transmission power of the terminal device should be based on the The transmission power is determined by the connection rate. Therefore, in the embodiment of the present application, before entering step S206, it is necessary to perform step S205 to determine whether the current connection rate of the terminal device has changed, if not, then proceed to step S206, otherwise, perform step S201 to re-determine the terminal device 'S current transmit power.

In step S206, the bit error rate of the first wireless signal is obtained;

In step S207, it is determined whether the bit error rate is less than a preset threshold, where the preset threshold is less than the maximum bit error rate allowed when the terminal device transmits the first wireless signal, and if so, step S208 is executed, otherwise, Go to step S209;

In step S208, the above-mentioned current transmission power is reduced by a first preset value;

In step S209, determine whether the error rate is greater than the maximum error rate;

In step S210, if the error rate is greater than the maximum error rate, the current transmit power is increased by a second preset value, where the first preset value is less than the second preset value;

The above steps S206-S210 are performed in exactly the same way as the steps S102-S106 in the first embodiment. For details, please refer to the description of the first embodiment, which will not be repeated here.

In the technical solution provided in Embodiment 2 of the present application, the current transmission power of the terminal device is adjusted on the basis of the transmission power determined by the connection rate of the terminal device. Therefore, Embodiment 2 of the present application can make When the terminal device has just performed wireless transmission, the bit error rate is relatively small.
