It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments.

acquiring a clean channel evaluation value of wireless communication;

In some embodiments, the step of determining whether the wireless communication is interfered according to the clean channel assessment value comprises:

judging whether the clean channel evaluation value is larger than a preset clean channel evaluation value threshold value or not;

if the clean channel assessment value is larger than the preset clean channel assessment value threshold value, determining that the wireless communication is interfered;

and if the clean channel assessment value is not greater than the preset clean channel assessment value threshold value, determining that the wireless communication is not interfered.

In some embodiments, the step of adjusting the parameter value of the wireless communication comprises:

acquiring the adjustment range of a preset parameter value;

and gradually reducing the parameter value of the wireless communication according to the preset parameter value adjustment amplitude until the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold.

determining a numerical range of the clean channel evaluation value;

acquiring a target parameter value according to the numerical value interval and a preset corresponding relation, wherein the preset corresponding relation comprises a corresponding relation between the numerical value interval and the target parameter value;

modifying the parameter value of the wireless communication to the target parameter value.

In some embodiments, the parameter values include receiving variable gain amplifier values and low noise amplifier values, the step of adjusting the parameter values for the wireless communication including:

acquiring a preset receiving variable gain amplifier value and a preset low noise amplifier value;

modifying a receiving variable gain amplifier value of the wireless communication to the preset receiving variable gain amplifier value;

and modifying the low noise amplifier value of the wireless communication into the preset low noise amplifier value.

In some embodiments, before the step of obtaining the clean channel assessment value of the wireless communication, the method further includes:

acquiring a received signal strength value of wireless communication;

judging whether the received signal strength value is greater than a preset signal strength threshold value or not;

and if the received signal strength value is greater than the preset signal strength threshold value, acquiring a clean channel evaluation value of wireless communication.

Referring to fig. 2, fig. 2 is a first flowchart illustrating an interference processing method according to an embodiment of the present disclosure. The interference processing method comprises the following steps:

a clean channel assessment value for the wireless communication is obtained 110.

The electronic equipment can communicate with other electronic equipment through wireless communication, so that data interaction with other electronic equipment is completed. The Wireless communication may include Wireless-Fidelity (Wi-Fi) communication and Radio Frequency (RF) communication.

Due to the wide application of the current wireless communication technology, a large number of wireless signals exist in the environment, such as wireless fidelity signals, radio frequency signals, bluetooth signals, and the like of other electronic devices, and further, wireless radiation signals generated when electronic devices such as cameras, sensors, and the like in the electronic devices work, and the like.

Therefore, when the electronic device performs wireless communication, the wireless signal of the electronic device is inevitably interfered by other electronic devices. Thus, an index of a Clear Channel Assessment (CCA) may be set in the electronic device. The index CCA reflects the degree of interference in the environment by a numerical value. The more severe the interference in the environment, the greater the CCA value.

Note that the CCA is also affected by the reception sensitivity of the electronic device when receiving the wireless signal. The smaller the reception sensitivity when the electronic device receives a wireless signal, the smaller the value of CCA.

When the electronic device performs wireless communication with other electronic devices, the electronic device may acquire a clear channel assessment value, that is, a CCA value, of the wireless communication in real time.

And 120, judging whether the wireless communication is interfered or not according to the clean channel evaluation value.

In the process of wireless communication between the electronic device and other electronic devices, when the electronic device is subjected to less interference, the influence of the interference in the environment on the wireless communication of the electronic device can be ignored, and at this time, the wireless communication of the electronic device can be considered to be not subjected to interference.

When the interference on the electronic device reaches a certain degree, so that the wireless communication quality of the electronic device is greatly affected, the interference in the environment may cause communication failure between the electronic device and other electronic devices, and the wireless communication of the electronic device is considered to be interfered.

After the electronic device obtains the clean channel evaluation value of the wireless communication, whether the wireless communication of the electronic device is interfered can be judged according to the clean channel evaluation value. If the wireless communication of the electronic device is not interfered, the electronic device may not perform processing, that is, not interfere with the wireless communication. If the wireless communication of the electronic device is interfered, the electronic device executes step 130 to intervene in the wireless communication.

And adjusting a parameter value of the wireless communication to reduce the clean channel estimate if the wireless communication is interfered, wherein the parameter value includes at least one of a received variable gain amplifier value and a low noise amplifier value.

And if the electronic equipment judges that the wireless communication is interfered, adjusting the parameter value of the wireless communication so as to reduce the clear channel assessment value CCA of the wireless communication.

Wherein the parameter value is related to a reception sensitivity of the electronic device to receive the wireless signal. The smaller the parameter value is, the smaller the receiving sensitivity of the electronic equipment for receiving the wireless signal is; the larger the parameter value, the greater the reception sensitivity of the electronic device to receive wireless signals. For example, the parameter value includes at least one of a receive variable gain amplifier value (Rx init VGA gain) and a low noise amplifier value (LNA gain).

When the electronic device performs wireless communication, in order to avoid collision with other wireless communication signals, the probability of transmitting a signal (TX) outwards is adjusted according to the value of the CCA. The larger the CCA, the less chance of TX in wireless communications. When the probability of TX is small, the performance of the electronic device for transmitting data to the outside in wireless communication is reduced, so that the stability of wireless communication is reduced.

In the embodiment of the application, the parameter value of the wireless communication is adjusted to reduce the CCA of the wireless communication, so that the probability of TX can be improved, and the performance of sending data to the outside by the electronic equipment in the wireless communication is improved, thereby improving the stability of the wireless communication.

In some embodiments, referring to fig. 3, fig. 3 is a second flowchart of an interference processing method according to an embodiment of the present disclosure.

Before acquiring the clear channel assessment value of the wireless communication in step 110, the method further includes the following steps:

140, obtaining a received signal strength value of the wireless communication;

150, judging whether the received signal strength value is greater than a preset signal strength threshold value;

Wherein, a preset signal intensity threshold value can be set in the electronic equipment. The preset signal strength threshold represents a boundary between the received signal of the electronic device being interfered by other wireless communication signals and not being interfered by other wireless communication signals. When the received signal strength of the electronic equipment is greater than the preset signal strength threshold value, it indicates that the received signal of the electronic equipment is less interfered, and the interference at this time can be ignored. When the received signal strength of the electronic equipment is smaller than or equal to the preset signal strength threshold value, the received signal of the electronic equipment is indicated to be greatly interfered.

The electronic device may obtain a Received Signal Strength Indicator (RSSI) of the wireless communication, and compare the RSSI with the preset Signal Strength threshold to determine whether the RSSI is greater than the preset Signal Strength threshold.

If the received signal strength value is greater than the preset signal strength threshold value, it is indicated that the received signal of the electronic device is less interfered at this time. At this time, the electronic apparatus acquires a clean channel evaluation value of the wireless communication.

For example, the electronic device obtains a received signal strength value of-50 dBm (decibel-milliwatt), and a preset signal strength threshold value of-60 dBm, where the received signal strength value of the electronic device is greater than the preset signal strength threshold value, and at this time, the electronic device obtains a clear channel assessment value CCA for wireless communication.

It should be noted that, when the RSSI of the electronic device during wireless communication is relatively large, for example, the RSSI is greater than the preset signal strength threshold, and the electronic device determines that the wireless communication is interfered according to the CCA of the wireless communication, it indicates that the wireless communication of the electronic device is not greatly affected by other wireless signals, but the TX communication channel of the wireless communication is occupied, which results in a decrease in the TX probability of the wireless communication, thereby causing the CCA of the wireless communication of the electronic device to be relatively large.

In some embodiments, referring to fig. 4, fig. 4 is a third flowchart illustrating an interference processing method according to an embodiment of the present disclosure.

Step 120, determining whether the wireless communication is interfered according to the clean channel assessment value, includes the following steps:

121, judging whether the clean channel assessment value is larger than a preset clean channel assessment value threshold value;

122, if the clean channel assessment value is greater than the preset clean channel assessment value threshold, determining that the wireless communication is interfered;

and 123, if the clean channel assessment value is not greater than the preset clean channel assessment value threshold, determining that the wireless communication is not interfered.

The electronic device may set a preset clear channel assessment value threshold, that is, a preset CCA threshold. The preset clean channel assessment value threshold may be a number, for example, 1500.

After the electronic equipment acquires a clean channel evaluation value of wireless communication, the clean channel evaluation value is compared with a preset clean channel evaluation value threshold value to judge whether the clean channel evaluation value is larger than the preset clean channel evaluation value threshold value.

If the clean channel assessment value is greater than the preset clean channel assessment value threshold, it is determined that the wireless communication is interfered, and then the electronic device executes step 130.

If the clean channel assessment value is not greater than the preset clean channel assessment value threshold, it is determined that the wireless communication is not interfered, and at this time, the electronic device may not process, that is, does not intervene in the wireless communication.

In some embodiments, with continued reference to fig. 4, adjusting 130 a parameter value of the wireless communication includes:

131, obtaining a preset parameter value adjustment range;

and 132, gradually reducing the parameter value of the wireless communication according to the preset parameter value adjustment range until the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold.

The electronic device can set the adjustment range of the preset parameter value. The preset parameter value may be adjusted by an adjustment ratio, for example, 5%. The adjustment range of the preset parameter value can also be a value, for example, 10.

The preset parameter value adjustment range may include an adjustment range for receiving a variable gain amplifier value, an adjustment range for receiving a low noise amplifier value, and both the adjustment range for receiving the variable gain amplifier value and the adjustment range for receiving the low noise amplifier value.

The electronic device may obtain the preset parameter value adjustment range, and gradually decrease the parameter value of the wireless communication according to the preset parameter value adjustment range until the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold.

For example, the electronic device may reduce the parameter value of the wireless communication by the adjustment amount, and then detect whether a CCA of the wireless communication is greater than a preset CCA threshold. If the CCA of the wireless communication is still larger than the preset CCA threshold, reducing the parameter value after the reduction of the adjustment range by the adjustment range, and then detecting whether the CCA of the wireless communication is larger than the preset CCA threshold again. The electronic device may continue to perform the above adjustment process until the adjustment is finished when the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold.

For example, the preset CCA threshold is 1500, the parameter value of the wireless communication is 100, the electronic device decreases the parameter value of the wireless communication by 5% to 95, the detected CCA is 1515, the electronic device decreases the parameter value of the wireless communication by 5% to 90 again, the CCA detected again is 1505, the electronic device decreases the parameter value of the wireless communication by 5% to 85 again, the CCA detected again is 1495, and the adjustment is ended.

In some embodiments, referring to fig. 5, fig. 5 is a fourth flowchart illustrating an interference processing method according to an embodiment of the present disclosure.

The step 130 of adjusting the parameter value of the wireless communication includes the following steps:

133, determining a value interval in which the clean channel assessment value is located;

134, obtaining a target parameter value according to the value interval and a preset corresponding relation, wherein the preset corresponding relation comprises a corresponding relation between the value interval and the target parameter value;

and 135, modifying the parameter value of the wireless communication into the target parameter value.

Wherein, a plurality of value intervals can be preset for the clean channel evaluation value in the electronic equipment. For example, a plurality of value ranges (0, 1500), (1500, 1550), (1550, 1600), (1600, 1650), (1650, 1700), and the like may be provided.

In addition, the electronic device may establish a correspondence between the value range and the target parameter value. In the corresponding relation, each value interval corresponds to one target parameter value. The target parameter value indicates that when the parameter value of the wireless communication is the target parameter value, the clean channel assessment value of the wireless communication is smaller than or equal to a preset clean channel assessment value threshold, that is, the CCA of the wireless communication is smaller than or equal to a preset CCA threshold.

For example, the correspondence between the value intervals and the target parameter values may be the correspondence shown in table 1:

TABLE 1

Interval of values	Target parameter value
(0，1500]	-
(1500，1550]	85
(1550，1600]	80
(1600，1650]	75
(1650，1700]	70
……	……

The electronic device may determine a value interval in which the obtained clean channel assessment value is located, and obtain a target parameter value according to the value interval and a preset corresponding relationship. Subsequently, the parameter value of the wireless communication is modified to the target parameter value. Thus, the CCA of the wireless communication may be controlled to be not greater than the preset CCA threshold.

For example, if the CCA acquired by the electronic device is 1620, the numerical interval in which the CCA is located is (1600, 1650), the electronic device acquires the target parameter value of 75 according to the numerical interval and the preset correspondence, and then, the electronic device modifies the parameter value of the wireless communication to 75.

In some embodiments, referring to fig. 6, fig. 6 is a fifth flowchart illustrating an interference processing method according to an embodiment of the present disclosure.

136, obtaining a preset receiving variable gain amplifier value and a preset low noise amplifier value;

137, modifying the receiving variable gain amplifier value of the wireless communication to the preset receiving variable gain amplifier value; and 138, modifying the low noise amplifier value of the wireless communication to the preset low noise amplifier value.

The parameter values wirelessly communicated by the electronic device include a receive variable gain amplifier value (Rx init VGA gain) and a low noise amplifier value (LNA gain).

A preset reception variable gain amplifier value (preset Rx init VGA gain) and a preset low noise amplifier value (preset LNA gain) may be preset in the electronic device. The preset Rx init VGA gain and the preset LNA gain indicate that when the Rx init VGA gain of the wireless communication is the preset Rx init VGA gain and the LNA gain of the wireless communication is the preset LNA gain, the clear channel assessment value of the wireless communication is less than or equal to a preset clear channel assessment value threshold, that is, the CCA of the wireless communication is less than or equal to a preset CCA threshold.

The electronic device may obtain a preset receive variable gain amplifier value and a preset low noise amplifier value. Subsequently, the reception variable gain amplifier value of the wireless communication is modified to the preset reception variable gain amplifier value, and the low noise amplifier value of the wireless communication is modified to the preset low noise amplifier value. Thus, the CCA of the wireless communication may be controlled to be not greater than the preset CCA threshold.

For example, if the preset Rx init VGA gain acquired by the electronic device is 80 and the preset LNA gain is 60, the electronic device modifies the Rx init VGA gain of the wireless communication to 80 and modifies the LNA gain to 60.

In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.

As can be seen from the above, the interference processing method provided in the embodiment of the present application includes: acquiring a clean channel evaluation value of wireless communication; judging whether the wireless communication is interfered or not according to the clean channel evaluation value; adjusting a parameter value of the wireless communication to reduce the clean channel assessment value if the wireless communication is interfered, wherein the parameter value comprises at least one of a receive variable gain amplifier value and a low noise amplifier value. In the interference processing method, when the wireless communication of the electronic equipment is interfered, the electronic equipment adjusts the parameter value of the wireless communication to reduce the clear channel evaluation value of the wireless communication, so that the probability of sending data in the wireless communication can be improved, the performance of sending data to the outside in the wireless communication of the electronic equipment can be further improved, and the stability of the wireless communication is further improved.

The embodiment of the application also provides an interference processing device, and the interference processing device can be integrated in electronic equipment. The electronic device can be a smart phone, a tablet computer, a notebook computer and the like.

the second acquisition module is used for acquiring a received signal strength value of the wireless communication;

the second judgment module is used for judging whether the received signal strength value is greater than a preset signal strength threshold value or not;

the first obtaining module is configured to obtain a clean channel assessment value of wireless communication if the received signal strength value is greater than the preset signal strength threshold value.

Referring to fig. 7, fig. 7 is a schematic view of a first structure of an interference processing apparatus according to an embodiment of the present application. Wherein the interference processing apparatus 200 comprises: a first obtaining module 201, a first judging module 202, and an adjusting module 203.

A first obtaining module 201, configured to obtain a clean channel assessment value of wireless communication.

Due to the wide application of the current wireless communication technology, a large number of wireless signals exist in the environment, such as wireless fidelity signals, radio frequency signals, bluetooth signals, and the like of other electronic devices, and further, wireless radiation signals generated when electronic devices such as cameras, sensors, and the like in the electronic devices operate, and the like.

When an electronic device performs wireless communication with other electronic devices, the first obtaining module 201 may obtain a clean channel assessment value, that is, a CCA value, of the wireless communication in real time.

A first determining module 202, configured to determine whether the wireless communication is interfered according to the clean channel assessment value.

After the first obtaining module 201 obtains the clean channel assessment value of the wireless communication, the first determining module 202 may determine whether the wireless communication of the electronic device is interfered according to the clean channel assessment value. If the wireless communication of the electronic device is not interfered, no processing, that is, no intervention in the wireless communication, may be performed. If the wireless communication of the electronic device is interfered, the adjustment module 203 continues to perform processing to intervene in the wireless communication.

An adjusting module 203, configured to adjust a parameter value of the wireless communication to reduce the clean channel assessment value if the wireless communication is interfered, where the parameter value includes at least one of a received variable gain amplifier value and a low noise amplifier value.

If the first determining module 202 determines that the wireless communication is interfered, the adjusting module 203 adjusts a parameter value of the wireless communication to reduce the clear channel assessment value CCA of the wireless communication.

In some embodiments, referring to fig. 8, fig. 8 is a schematic diagram of a second structure of an interference processing apparatus according to an embodiment of the present disclosure. Wherein, the interference processing apparatus 200 further comprises: a second obtaining module 204 and a second judging module 205.

A second obtaining module 204, configured to obtain a received signal strength value of the wireless communication;

a second determining module 205, configured to determine whether the received signal strength value is greater than a preset signal strength threshold;

the first obtaining module 201 is configured to obtain a clean channel assessment value of wireless communication if the received signal strength value is greater than the preset signal strength threshold.

The second obtaining module 204 may obtain a Received Signal Strength Indicator (RSSI) of the wireless communication, and the second determining module 205 compares the RSSI with the preset Signal Strength threshold to determine whether the RSSI is greater than the preset Signal Strength threshold.

If the received signal strength value is greater than the preset signal strength threshold value, it is indicated that the received signal of the electronic device is less interfered at this time. At this time, the first acquisition module 201 acquires a clean channel assessment value of wireless communication.

For example, the received signal strength value acquired by the second acquiring module 204 is-50 dBm (decibel-milliwatt), and the preset signal strength threshold is-60 dBm, the received signal strength value of the electronic device is greater than the preset signal strength threshold, and at this time, the first acquiring module 201 acquires the clear channel assessment value CCA of the wireless communication.

It should be noted that, when the RSSI of the electronic device during wireless communication is relatively large, for example, the RSSI is greater than the preset signal strength threshold, and the first determining module 202 determines that the wireless communication is interfered according to the CCA of the wireless communication, it indicates that the wireless communication of the electronic device is not greatly affected by other wireless signals, but the TX communication channel of the wireless communication is occupied, which results in a decrease in the TX probability of the wireless communication, thereby causing the CCA of the wireless communication of the electronic device to be relatively large.

In some embodiments, the first determining module 202 is configured to perform the following steps:

After the first obtaining module 201 obtains the clean channel assessment value of the wireless communication, the first determining module 202 compares the clean channel assessment value with the preset clean channel assessment value threshold to determine whether the clean channel assessment value is greater than the preset clean channel assessment value threshold.

If the clean channel assessment value is greater than the preset clean channel assessment value threshold, it is determined that the wireless communication is interfered, and then the adjustment module 203 performs processing.

If the clean channel assessment value is not greater than the preset clean channel assessment value threshold, it is determined that the wireless communication is not interfered, and at this time, processing may not be performed, that is, the wireless communication is not interfered.

In some embodiments, the adjustment module 203 is configured to perform the following steps:

acquiring the adjustment range of a preset parameter value;

The adjusting module 203 may obtain the preset parameter value adjustment range, and gradually decrease the parameter value of the wireless communication according to the preset parameter value adjustment range until the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold.

For example, the adjusting module 203 may reduce the parameter value of the wireless communication by the adjustment magnitude, and detect whether the CCA of the wireless communication is greater than a preset CCA threshold. If the CCA of the wireless communication is still larger than the preset CCA threshold, reducing the parameter value after the reduction of the adjustment range by the adjustment range, and then detecting whether the CCA of the wireless communication is larger than the preset CCA threshold again. The adjusting module 203 may continue the adjusting process until the clean channel assessment value of the wireless communication is not greater than the preset clean channel assessment value threshold, and the adjusting is finished.

For example, the CCA threshold is 1500, the parameter value of the wireless communication is 100, the adjusting module 203 decreases the parameter value of the wireless communication by 5% to 95, the detected CCA is 1515, the adjusting module 203 decreases the parameter value of the wireless communication by 5% to 90 again, the CCA detected again is 1505, the adjusting module 203 decreases the parameter value of the wireless communication by 5% to 85 again, the CCA detected again is 1495, and the adjustment is completed.

determining a numerical range of the clean channel evaluation value;

For example, the correspondence between the value intervals and the target parameter values may be the correspondence shown in table 2:

TABLE 2

The adjusting module 203 may determine a value interval where the obtained clean channel assessment value is located, and obtain a target parameter value according to the value interval and a preset corresponding relationship. Subsequently, the parameter value of the wireless communication is modified to the target parameter value. Thus, the CCA of the wireless communication may be controlled to be not greater than the preset CCA threshold.

For example, if the CCA acquired by the adjustment module 203 is 1620, the value interval where the CCA is located is (1600, 1650), the adjustment module 203 acquires the target parameter value of 75 according to the value interval and the preset correspondence, and then the adjustment module 203 modifies the parameter value of the wireless communication to 75.

The adjusting module 203 may obtain a preset receive variable gain amplifier value and a preset low noise amplifier value. Subsequently, the reception variable gain amplifier value of the wireless communication is modified to the preset reception variable gain amplifier value, and the low noise amplifier value of the wireless communication is modified to the preset low noise amplifier value. Thus, the CCA of the wireless communication may be controlled to be not greater than the preset CCA threshold.

For example, if the preset Rx init VGA gain acquired by the adjusting module 203 is 80 and the preset LNA gain is 60, the adjusting module 203 modifies the Rx init VGA gain of the wireless communication to 80 and modifies the LNA gain to 60.

In specific implementation, the modules may be implemented as independent entities, or may be combined arbitrarily and implemented as one or several entities.

As can be seen from the above, in the interference processing apparatus 200 provided in the embodiment of the present application, the first obtaining module 201 obtains a clean channel assessment value of wireless communication; the first judging module 202 judges whether the wireless communication is interfered according to the clean channel assessment value; if the wireless communication is interfered, the adjusting module 203 adjusts a parameter value of the wireless communication to reduce the clean channel assessment value, wherein the parameter value includes at least one of a received variable gain amplifier value and a low noise amplifier value. In the interference processing device, when wireless communication of the electronic equipment is interfered, the parameter value of the wireless communication is adjusted to reduce the clear channel evaluation value of the wireless communication, so that the probability of sending data in the wireless communication can be improved, the performance of sending data to the outside in the wireless communication of the electronic equipment can be improved, and the stability of the wireless communication is improved.

The embodiment of the application also provides the electronic equipment. The electronic device can be a smart phone, a tablet computer, a notebook computer and the like.
