Background

When the connection between the earphone and the electronic device is interfered greatly (for example, when the earphone is far away from the electronic device), the earphone can request the electronic device to improve the transmitting power, so that the communication quality between the earphone and the electronic device is ensured. However, in order to ensure the efficiency of radio reception and improve the hearing experience of the user, the electronic device is always required to increase the transmission power until the electronic device increases the transmission power to the highest transmission power, so that the user can not consider the actual communication situation. The electronic device will also boost the transmit power to the highest transmit power directly upon request of the headset. However, part of the application scenario of the headset does not require as high a transmit power, so that it is easy to cause waste of power consumption.

As shown in fig. 1, when the connection between the earphone and the electronic device is greatly interfered (for example, when the earphone is far away from the electronic device), the earphone requests the electronic device to increase the transmitting power, but after the electronic device is connected, some earphones do not consider the actual situation, and always request the electronic device to increase the transmitting power until the electronic device increases the transmitting power to the highest transmitting power of the electronic device, for example, the highest transmitting power is the power corresponding to Powerlever 10. During the above period, the earphone will always send a request for increasing the transmission power to the electronic device, and will not stop sending the request for increasing the transmission power until the transmission power of the electronic device is increased to the power corresponding to the Powerlever 10. The electronic device may increase the transmit power to the highest level, such as to the power corresponding to Powerlever 10, based on the request from the headset. However, sometimes the application scenario of the earphone does not need as high a transmission power, and the above process and result inevitably result in waste of power consumption.

In order to solve the problem that in the above process, the electronic device always increases the transmission power according to the request of increasing the transmission power of the earphone, thereby causing the wasting behavior of power consumption, the embodiment of the application provides a transmission power adjustment method, so as to avoid the problem of abnormally increasing the power consumption caused by continuously increasing the transmission power when the earphone is in a music scene. Specifically, when the earphone requests to increase the transmitting power, the embodiment of the application determines whether to increase the transmitting power or not by judging the application scene, so that the power consumption waste caused by the increase of the transmitting power by the electronic equipment according to the unreasonable transmitting power increasing request provided by the earphone can be avoided.

It is understood that the electronic device in the present application may be a mobile phone, tablet, desktop, laptop, handheld, notebook, ultra-mobile personal computer (UMPC), netbook, as well as a cellular phone, personal digital assistant (personal digital assistant, PDA), artificial intelligence (artificial intelligence, AI) device, wearable device, vehicle-mounted device, smart home device, and/or smart city device. The embodiment of the present application does not particularly limit the specific form of the apparatus. The earphone in the application can also be other bluetooth playing equipment, such as a bluetooth sound box and the like.

The following describes in detail the method for adjusting the transmit power provided in the present application with reference to the accompanying drawings.

Fig. 2 is a schematic diagram of signaling interaction between a headset and an electronic device. As shown in fig. 2, the headset may request the electronic device to increase the transmit POWER by sending LMP-INCR-POWER-REQ signaling to the electronic device. The electronic device will increase the transmit POWER based on the LMP-INCR-POWER-REQ signaling sent by the headset. Specifically, the electronic device increases the transmission POWER according to the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling, and it is understood that different LMP-INCR-POWER-REQ signaling may correspond to the same or different transmission POWER increase values, and the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling may be set according to the actual situation, which is not limited herein.

If the electronic device receives the LMP-INCR-POWER-REQ signaling sent by the headset and determines that the current transmitting POWER is the highest transmitting POWER (for example, the highest transmitting POWER is the POWER corresponding to Powerlever 10), the electronic device sends the LMP-MAX-POWER signaling to the headset, and informs that the transmitting POWER of the current electronic device of the headset is the highest transmitting POWER, and cannot continue to increase the POWER request. When the earphone receives the LMP-MAX-POWER signaling, the earphone stops sending the POWER increasing request to the electronic equipment.

And the electronic equipment increases the transmitting POWER according to the transmitting POWER increasing value corresponding to the LMP-INCR-POWER-REQ signaling. It is to be understood that the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling may be set according to practical situations, and different two LMP-INCR-POWER-REQ signaling may correspond to different transmission POWER increase values, which is not limited herein.

In the signaling interaction process shown in fig. 2, the earphone always sends LMP-INCR-POWER-REQ signaling to the electronic device, so that the transmitting POWER of the electronic device is increased to the highest transmitting POWER. In order to solve the above-mentioned problem, the embodiment of the present application provides a method for adjusting transmission power shown in fig. 3. The method is applied to the electronic equipment. The electronic device may include bluetooth firmware (Blutooth Controller, BTC), and the method may be applied to the BTC of the electronic device. The electronic device establishes a bluetooth connection with the headset, as shown in fig. 3, the method may include:

301, receiving LMP-INCR-POWER-REQ signaling sent by the headset.

The LMP-INCR-POWER-REQ signaling is used to request the electronic device to increase the transmit POWER. It will be appreciated that the LMP-INCR-POWER-REQ signaling is merely illustrative, and that the headset may request the electronic device to increase the transmit POWER by sending other commands.

302, it is determined whether the communication quality with the headset meets a preset communication threshold.

After receiving the LMP-INCR-POWER-REQ signaling sent by the earphone, the electronic equipment determines the communication quality with the earphone and determines whether the communication quality with the earphone meets a preset communication threshold.

In some embodiments of the present application, the communication quality includes a retransmission rate, where the retransmission rate is used to determine an efficiency of data transmission from the electronic device to the headset, and may be a probability that the electronic device retransmits a signal to the headset. The determining whether the communication quality with the earphone meets a preset communication threshold comprises: determining whether a retransmission rate with the headset is less than or equal to the retransmission rate threshold; if the retransmission rate between the communication terminal and the earphone is smaller than or equal to the retransmission rate threshold, determining that the communication quality between the communication terminal and the earphone meets a preset communication threshold; and if the retransmission rate between the wireless communication terminal and the earphone is determined to be larger than the retransmission rate threshold, determining that the communication quality between the wireless communication terminal and the earphone does not meet the preset communication threshold.

The retransmission rate threshold may be set according to practical situations, for example, set to 50%. If the retransmission rate between the electronic equipment and the earphone is less than or equal to 50%, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets the preset communication threshold. If the retransmission rate between the electronic equipment and the earphone is determined to be more than 50%, the electronic equipment determines that the communication quality between the electronic equipment and the earphone does not meet the preset communication threshold.

In some embodiments of the present application, the communication quality includes an indication of a strength (Received Signal Strength Indicator, RSSI) of a received signal of the headset, and the determining whether the communication quality with the headset meets a preset communication threshold includes: determining whether the RSSI with the headset is less than or equal to an intensity threshold; if the electronic equipment determines that the RSSI of the earphone is smaller than or equal to the strength threshold, the electronic equipment determines that the communication quality between the electronic equipment and the earphone does not meet the preset communication threshold. If the electronic equipment determines that the RSSI of the earphone is larger than the strength threshold, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets the preset communication threshold.

In some embodiments of the present application, the communication quality includes an error rate of the headset, where the error rate may be an error probability of the headset transmitting a signal to the electronic device. The determining whether the communication quality with the earphone meets a preset communication threshold comprises: determining whether the bit error rate with the earphone is less than or equal to a bit error rate threshold; if the electronic equipment determines that the error rate of the earphone is smaller than or equal to the error rate threshold, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets the preset communication threshold. If the electronic equipment determines that the error rate of the earphone is larger than the error rate threshold, the electronic equipment determines that the communication quality between the electronic equipment and the earphone does not meet the preset communication threshold.

If it is determined that the communication quality with the headset meets the preset communication threshold, 303 is performed without increasing the transmit power. If it is determined that the communication quality with the headset meets the preset communication threshold, 304 is performed, and the transmission power is increased.

As shown in fig. 3, the current transmission Power of the electronic device is illustrated by taking Power corresponding to Power Level 7 as an example, if it is determined that the communication quality with the earphone meets the preset communication threshold, the transmission Power is not increased, that is, the Power corresponding to the current transmission Power Level 7 is maintained; if the communication quality of the earphone does not meet the preset communication threshold, the current transmitting Power is increased from the Power corresponding to the Power Level 7 to the Power corresponding to the Power Level 8. In some embodiments of the present application, 302 in fig. 3, after determining whether the communication quality with the headset meets the preset communication threshold, the method further includes: counting the times of not increasing the transmitting POWER after receiving the LMP-INCR-POWER-REQ signaling sent by the earphone; and if the times meet the preset number conditions, sending LMP-MAX-POWER signaling to the earphone.

The LMP-MAX-POWER signaling is used to indicate that the current transmit POWER of the electronic device is the highest transmit POWER, and the transmit POWER cannot be continuously increased, so that the earphone can be informed of: the electronic device is already at the highest transmit power and cannot increase the transmit power any more. By sending LMP-MAX-POWER signaling to the headset, the headset may be prevented from continuing to send transmit POWER increase requests to the electronic device. It can be understood that the LMP-MAX-POWER signaling is only illustrated here, and the electronic device may also inform the headset that the current transmission POWER is the highest transmission POWER and the transmission POWER cannot be continuously increased by sending other instructions to the headset, so as to avoid that the headset continuously sends a transmission POWER increasing request to the electronic device.

The number of times that the electronic device does not increase the transmission POWER after receiving the LMP-INCR-POWER-REQ signaling sent by the headset after the electronic device is connected with the headset can be counted. Or, the number of times that the transmitting POWER is not increased after receiving the LMP-INCR-POWER-REQ signaling sent by the headset in the preset time period may be counted. The preset time period can be set according to actual conditions. For example, the preset time period may include a time period from when the electronic device last increased the transmission power to a current time. When the transmitting power is not increased after the electronic device establishes the bluetooth connection with the earphone, the preset time period may also include a time period from the time when the electronic device establishes the bluetooth connection with the earphone to the current time.

The preset number of conditions may include a preset number of thresholds, and the determining whether the number of times satisfies the preset number of conditions includes: whether the number of times is greater than or equal to a preset number threshold may be set according to actual conditions, and is not limited herein, for example, the preset number threshold may be set to 1, 2, 3, or the like.

In some embodiments of the present application, when the preset number threshold is set to 1, the method includes: and if the LMP-INCR-POWER-REQ signaling sent by the earphone is received, determining that the communication quality with the earphone meets a preset communication threshold, and sending the LMP-MAX-POWER signaling to the earphone. That is, when it is determined that the communication quality with the headset satisfies the preset communication threshold after receiving the LMP-INCR-POWER-REQ signaling transmitted by the headset for the first time, the LMP-MAX-POWER signaling is directly transmitted to the headset to prevent the headset from continuing to transmit the transmission POWER increase request to the electronic device. When the first time that the earphone requests the electronic equipment to increase the transmitting POWER under the condition of normal communication quality is found, the LMP-MAX-POWER signaling is directly sent to the earphone, so that the subsequent earphone can be prevented from continuously requesting the electronic equipment to increase the transmitting POWER under the condition of normal communication quality.

When the value of the preset number threshold is set to be larger, if the number of times of not increasing the transmission POWER after receiving the LMP-INCR-POWER-REQ signaling sent by the headset satisfies the preset number condition, it may be determined that: and when the communication quality meets a preset communication threshold, the earphone requests the electronic equipment to increase the request times of the transmission power. When the communication quality of the earphone meets the preset communication threshold, and the number of times of requesting the electronic equipment to increase the transmission POWER is large, the LMP-MAX-POWER signaling is sent to the earphone, so that the situation that the earphone always requests the electronic equipment to increase the transmission POWER when the communication quality meets the preset communication threshold can be avoided. Meanwhile, under the condition that the number of times of requesting the electronic equipment for increasing the transmitting POWER by the earphone when the communication quality meets the preset communication threshold is determined to be more, the LMP-MAX-POWER signaling is sent to the earphone to prevent the earphone from continuously sending the request for increasing the transmitting POWER, so that the situation that the earphone directly refuses to request the electronic equipment for increasing the transmitting POWER after the earphone requests the electronic equipment for increasing the transmitting POWER once by accident when the communication quality meets the preset communication threshold can be avoided, and the earphone cannot normally request the electronic equipment for increasing the transmitting POWER is avoided.

According to the embodiment, when the earphone requests to increase the transmission power, whether to increase the transmission power is determined according to the communication quality with the earphone, and when the retransmission rate of the earphone is determined to meet the preset increasing condition, the transmission power of the electronic equipment is increased, so that the power consumption waste caused by increasing the transmission power when the electronic equipment increases the transmission power according to the unreasonable transmission power increasing request made by the earphone can be avoided.

The number of times that the transmission POWER is not increased after receiving the LMP-INCR-POWER-REQ signaling sent by the headset satisfies a preset number of conditions, and when the LMP-MAX-POWER signaling is sent to the headset, the transmission POWER of the electronic device may not actually reach the highest transmission POWER of the electronic device. Some specific embodiments after the electronic device sends LMP-MAX-POWER signaling to the earphone are described below in connection with the embodiments.

In some embodiments of the present application, after sending LMP-MAX-POWER signaling to the headset, the method further comprises: and determining whether the communication quality with the earphone meets a preset communication threshold according to a preset time interval. And if the communication quality with the earphone is determined not to meet the preset communication threshold, actively increasing the transmitting power. If the communication quality with the earphone meets the preset communication threshold, no processing is performed, and the process is ended. It will be appreciated that the above method may be performed when the current transmit power of the electronic device is not the highest transmit power, but the headset is informed that the current transmit power is the highest transmit power. If the current transmit power of the electronic device is the highest transmit power, the above method is not performed.

By the method, the situation that the transmission efficiency between the electronic equipment and the earphone is low because the electronic equipment cannot actively improve the transmission power when the current transmission power of the electronic equipment cannot meet the normal communication with the earphone after the method is executed when the current transmission power of the electronic equipment is not the highest transmission power but the current transmission power is notified to the earphone is the highest transmission power can be avoided, and therefore the accuracy of transmission power adjustment is improved.

When the earphone and the electronic device shown in fig. 2 perform signaling interaction, after each time the electronic device receives a request for increasing the transmission power sent by the earphone, the electronic device directly increases the transmission power according to the request, and does not reply to the request for the transmission power of the earphone except for the case that the current transmission power is the highest transmission power. In some embodiments, however, the electronic device replies to the transmit power increase request of the headset each time the transmit power increase request sent by the headset is received, as shown in fig. 4. Fig. 4 is a schematic diagram of signaling interaction between a headset and an electronic device. As shown in fig. 4, the headset may request the electronic device to increase the transmit POWER by sending LL-POWER-CONTROL-REQ signaling to the electronic device. The electronic device increases the transmit POWER based on the LL-POWER-CONTROL-REQ signaling sent by the headset, and sends an LL-POWER-CONTROL-RSP command to the headset after the transmit POWER is increased.

As shown in table 1, three CONTROL parameters (CtrData) may be included in the LL-POWER-CONTROL-REQ signaling: physical (PHY), differential (Delta), transmit power (TxPower). Wherein PHY is used to represent signals used for signaling. Delta is used to indicate a transmission power value requested to be changed, positive number indicates a transmission power value requested to be increased, and negative number indicates a transmission power value requested to be decreased. For example, delta 1 indicates a request to increase the transmit power by 1db, and Delta-1 indicates a request to decrease the transmit power by 1 db. TxPower represents the current transmit power of the home terminal. If one earphone sends out LL-POWER-CONTROL-REQ signaling, txPOwer in the instruction indicates the current transmitting POWER of the earphone.

TABLE 1

As shown in table 2, six CONTROL parameters (CtrData) may be included in the LL-POWER-CONTROL-RSP signaling: minimum (Min); maximum value (Max); reserved bits (Reserved for future use, RFU); difference (Delta), transmit power (TxPower), acceptable maximum power reduction value (Acceptable Power Reduction, APR). Where Min is used to indicate whether the current is the minimum transmit power, min 0 indicates that the current is not the minimum transmit power, and Min 1 indicates that the current is the minimum transmit power. Max is used to indicate whether the maximum transmit power is currently present, max 0 is not currently present, max 1 is currently present. Delta is used to represent the current changed transmit power value, positive number represents the current increased transmit power value, and negative number represents the current decreased transmit power value. For example, delta 1 represents the current 1db increase in transmit power, and Delta-1 represents the current 1db decrease in transmit power. TxPower represents the current transmit power of the home terminal. If an electronic device sends LL-POWER-CONTROL-RSP signaling, txPOwer in the instruction indicates the current transmitting POWER of the electronic device.

TABLE 2

For convenience of description, in the signaling interaction shown in fig. 4, key control parameters in each signaling are added to represent specific content corresponding to each signaling. For example, LL-POWER-CONTROL-REQ (Delta 1) is used to indicate that the headset requests an increase in transmit POWER of 1db from the electronic equipment. The LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 8) indicates that the electronic equipment has increased by 1db of transmit POWER (Delta 1) according to the LL-POWER-CONTROL-REQ (Delta 1) signaling, the transmit POWER of the current electronic equipment is the POWER corresponding to POWER level 8 (TxPower 8), and the transmit POWER of the current electronic equipment is not the maximum transmit POWER (Max 0).

If the electronic device increases the transmission POWER, and then determines that the current transmission POWER is the highest transmission POWER (for example, the highest transmission POWER is the POWER corresponding to the POWER lever 10), the electronic device sends an LL-POWER-CONTROL-RSP (Max 1,Delta 1,Txpower 10) signaling to the earphone, and informs the earphone that the transmission POWER (Delta 1) is increased by 1db according to the LL-POWER-CONTROL-REQ signaling, and the current transmission POWER of the electronic device is the POWER corresponding to the POWER lever 10, which is the highest transmission POWER (Max 1), and cannot continue to increase the POWER request. When the earphone receives the LL-POWER-CONTROL-RSP signaling with the Max of 1, the earphone stops sending the POWER-up request to the electronic equipment.

In the signaling interaction process shown in fig. 4, the earphone always sends the LL-POWER-CONTROL-REQ signaling to the electronic device, so that the transmitting POWER of the electronic device is increased to the highest transmitting POWER. In order to solve the above-mentioned problem, the embodiment of the present application provides a method for adjusting transmission power as shown in fig. 5. The method is applied to the electronic equipment. The electronic device may include bluetooth firmware (Blutooth Controller, BTC), and the method may be applied to the BTC of the electronic device. The electronic device establishes a bluetooth connection with the headset, as shown in fig. 5, the method may include:

501, receiving LL-POWER-CONTROL-REQ signaling.

For example, LL-POWER-CONTROL-REQ (Delta 1) signaling is used to request the electronic equipment to increase the transmit POWER by 1 db.

502, it is determined whether the communication quality with the headset meets a preset communication threshold.

After receiving the LL-POWER-CONTROL-REQ signaling sent by the earphone, the electronic equipment determines the communication quality with the earphone and determines whether the communication quality with the earphone meets a preset communication threshold.

If it is determined that the communication quality with the earphone meets the preset communication threshold, executing 503 without increasing the transmission power; if it is determined that the communication quality with the headset meets the preset communication threshold, 504 is performed, and the transmit power is increased.

After the electronic device increases the transmit POWER based on the LL-POWER-CONTROL-REQ signaling, the electronic device may send LL-POWER-CONTROL-RSP signaling, such as LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 8), to the headset. As shown in fig. 5, the current transmission Power of the electronic device is illustrated by taking Power corresponding to Power Level 7 as an example, if it is determined that the communication quality with the earphone meets the preset communication threshold, the transmission Power is not increased, that is, the Power corresponding to the current transmission Power Level 7 is maintained; if the communication quality of the earphone does not meet the preset communication threshold, the current transmitting Power is increased from the Power corresponding to the Power Level 7 to the Power corresponding to the Power Level 8.

According to the embodiment, when the earphone requests to increase the transmission power, whether to increase the transmission power is determined according to the communication quality with the earphone, and when the retransmission rate with the earphone is determined to meet the preset increasing condition, the transmission power of the electronic equipment is increased, so that the power consumption waste caused by increasing the transmission power when the electronic equipment increases the transmission power according to the unreasonable transmission power increasing request made by the earphone can be avoided.

In some embodiments of the present application, as shown in fig. 6, in fig. 5, after determining whether the communication quality with the headset meets the preset communication threshold, the electronic device performs 601 and sends a rejection signaling to the headset if it is determined that the communication quality with the headset meets the preset communication threshold. The rejection signaling indicates that the increase of the transmission power according to the request for increasing the transmission power is rejected, and can be used for informing the Bluetooth playing device that the transmission power is not increased. As shown in fig. 7, the transmission POWER before the electronic device receives the LL-POWER-CONTROL-REQ signaling is POWER corresponding to POWER lever 7, and after the electronic device determines that the communication quality with the headset meets the preset communication threshold, the electronic device sends LL-POWER-CONTROL-RSP (Max 0,Delta 0,Txpower 7) to the headset, where Delta 0 indicates that the transmission POWER is not increased according to the LL-POWER-CONTROL-REQ signaling. It will be appreciated that, if the next time the electronic device receives the LL-POWER-CONTROL-REQ signaling again and determines that the communication quality with the headset still meets the preset communication threshold, the electronic device continues to send a reject signaling to the headset, i.e. sends LL-POWER-CONTROL-RSP (Max 0,Delta 0,Txpower 7).

In some embodiments of the present application, after executing 502 in fig. 5 to determine whether the communication quality with the headset meets the preset communication threshold, the electronic device may count the number of times that the LL-POWER-CONTROL-REQ signaling sent by the headset is received without increasing the transmission POWER; and if the times meet the preset number conditions, sending an improvement signaling to the earphone.

Some specific embodiments for counting the number of times that the LL-POWER-CONTROL-REQ signaling sent by the receiving earphone does not increase the transmit POWER may refer to the description related to counting the number of times that the LMP-INCR-POWER-REQ signaling sent by the receiving earphone in fig. 3 does not increase the transmit POWER, and the preset number of conditions may refer to the description related to the embodiment in fig. 3, which is not repeated herein.

In some embodiments of the present application, the number of times the electronic device sends the rejection signaling to the earpiece may be determined as the number of times the transmit POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the earpiece.

The boost signaling is used to tell the headset that the transmit power has been boosted. It will be appreciated that the enhancement signaling transmitted when the transmit power is not increased may be in the same format as the enhancement signaling transmitted when the transmit power is increased, or may be different. When the earphone receives the increasing signaling sent when the transmitting power is increased and the increasing signaling sent when the transmitting power is not increased, the electronic equipment can be determined to have increased the transmitting power. For example, when the transmitting POWER of an electronic device is the POWER corresponding to the POWER lever7, and when the electronic device receives the LL-POWER-CONTROL-REQ (Delta 1) signaling, it is determined that the number of times of meeting the preset communication threshold with the communication quality of the headset in the period from the last time of increasing the transmitting POWER to the current time meets the preset number of conditions, if it is determined that the number of continuous transmission times of the reject signaling is greater than or equal to the preset reject number threshold, the transmitting POWER is not increased, the LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 8) is directly sent to the headset, and it is notified that the transmitting POWER of the headset has been increased by 1db according to the LL-POWER-CONTROL-REQ (Delta 1) signaling, the transmitting POWER of the current electronic device is the POWER corresponding to the POWER lever8, and the transmitting POWER of the current electronic device is not the maximum transmitting POWER, and in fact, the transmitting POWER of the electronic device is not increased, and the current transmitting POWER of the electronic device is still the POWER corresponding to the POWER of the POWER lever 7.

It can be understood that after the electronic device does not increase the transmission POWER and sends the increase signaling to the headset, if the LL-POWER-CONTROL-REQ signaling is received again and it is determined that the communication quality with the headset meets the preset communication threshold, the transmission POWER is still not increased, and the increase signaling is continuously sent to the headset once. It will be appreciated that the enhancement signaling sent by the electronic device at different times may be different without the electronic device enhancing the transmit power. For example, in the case where the electronic device does not increase the transmission POWER, the first transmission enhancement signaling sent by the electronic device a to the headset a may be LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 8), and the second transmission enhancement signaling sent by the electronic device a to the headset a may be LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 9), where the first transmission time is earlier than the second transmission time. That is, multiple boost signaling sent by an electronic device to the same headset may be different without the electronic device boosting the transmit power. For example, the Txpower value in the up signaling with the subsequent transmission time may be greater than the Txpower value in the up signaling with the previous transmission time. Under the condition that the electronic equipment does not increase the transmitting power, different increasing signaling is sent to the earphone, and the situation that the same increasing signaling is always sent to the earphone to cause the error reporting of the earphone can be avoided.

Further, in some embodiments of the present application, if the number of times of sending the boost signaling to the headset without boosting the power is greater than a preset number of times, the highest power signaling is sent to the headset. By sending the highest power signaling to the headset, it is avoided that the headset always requests an increase in transmit power from the electronic device.

The highest power signaling is used to tell the headset: the current transmitting power of the electronic equipment is the highest transmitting power, and the transmitting power cannot be continuously increased. By sending the highest POWER signaling (e.g., sending LL-POWER-CONTROL-REQ signaling) to the headset when the actual transmit POWER of the electronic device is not the highest transmit POWER, the headset may be prevented from continuing to send transmit POWER boost requests to the electronic device. For example, the highest POWER signaling may be LL-POWER-CONTROL-RSP (Max 1,Delta A,Txpower B), max 1 indicates that the current transmission POWER of the electronic device is the highest transmission POWER, a is a number greater than 0, a is a transmission POWER value informing that the headset is improved (the actual electronic device may not improve the transmission POWER), and the specific value of a may be set according to the actual situation. The earphone can determine the transmitting power of the electronic device according to the TxPower B in the instruction, so the value of B is larger than the transmitting power of the electronic device which the earphone knows last time. For example, if the last signaling sent by the electronic device to the headset is LL-POWER-CONTROL-RSP (Max 0,Delta 1,Txpower 7), the highest POWER signaling sent by the electronic device to the headset this time may be LL-POWER-CONTROL-RSP (Max 1,Delta A,Txpower B), where the value of B should be greater than 7 and the value of B may be equal to the value of a plus 7.

It can be appreciated that in some embodiments of the present application, the electronic device may count the number of times that the transmit POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset; and if the times meet the preset number of conditions, directly sending the highest power instruction to the earphone. In other embodiments of the present application, when the electronic device determines that the communication quality with the headset satisfies the preset communication threshold after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset, the highest POWER instruction may be directly sent to the headset.

In some embodiments of the present application, after executing 502 in fig. 5 and determining whether the communication quality with the headset meets the preset communication threshold, the electronic device may count the number of times of sending the rejection signaling; and if the transmission times meet the preset number of conditions, sending an improvement signaling or a highest power signaling to the earphone. It can be understood that, in this embodiment, after sending the enhancement signaling to the earphone if the number of sending times satisfies a preset number of conditions, counting the number of times of sending the enhancement signaling; and if the number of times of sending the enhancement signaling to the earphone is larger than the preset number of times, sending the highest-power signaling to the earphone.

In some embodiments of the present application, after sending the highest power signaling to the earphone, it may be determined, according to a preset time interval, whether the communication quality with the earphone meets a preset communication threshold. And if the communication quality with the earphone is determined not to meet the preset communication threshold, actively increasing the transmitting power. If the communication quality with the earphone meets the preset communication threshold, no processing is performed, and the process is ended. The preset time interval may be set according to actual situations, and is not limited in any way. By the method, the situation that the transmission efficiency between the electronic equipment and the earphone is low because the electronic equipment cannot actively improve the transmission power when the current transmission power of the electronic equipment cannot meet the normal communication with the earphone after the method is executed when the current transmission power of the electronic equipment is not the highest transmission power but the earphone is informed of the fact that the current transmission power is the highest transmission power can be avoided, and the accuracy of transmission power adjustment is improved.

It can be appreciated that the electronic device may or may not notify the headset after actively increasing the transmit power. For example, the electronic device may inform the headset that the transmit POWER has been increased, such as POWER up signaling, through LL-POWER-CONTROL-IND signaling. As shown in table 3, six CONTROL parameters (CtrData) may be included in the LL-POWER-CONTROL-IND signaling: minimum (Min); maximum value (Max); reserved bits (Reserved for future use, RFU); difference (Delta), transmit power (TxPower), physical channel (PHY). The specific meaning of each control parameter in table 3 can be referred to the description of the relevant control parameters in table 1 and table 2, and will not be described herein.

TABLE 3 Table 3

For example, after the electronic device actively increases the transmission POWER (the transmission POWER before the increase is POWER lever7 and the transmission POWER after the active increase is POWER lever 8), a LL-POWER-CONTROL-IND (Max 0,Delta 1,Txpower 8) signaling is sent to the earphone, informing the earphone that the transmission POWER of 1db is increased, where the transmission POWER of the current electronic device is the POWER corresponding to POWER lever8 and the transmission POWER of the current electronic device is not the maximum transmission POWER. It will be appreciated that the earpiece receives

LL-POWER-CONTROL-IND signaling, when it is determined that the electronic device is not currently at the highest transmit POWER, the electronic device will continue to request to increase the transmit POWER, where the current situation may be processed according to the method shown in fig. 5 and the method in the embodiment related to fig. 5, for example, when the request for increasing the transmit POWER unreasonable to the headset is denied or when the request for increasing the transmit POWER unreasonable to the headset is made, the increase signaling or the highest POWER signaling is sent to the headset.
