[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The Bluetooth transmission power compensation method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, wireless communication can be performed between the first device 102 and the second device 104, including WiFi communication, Bluetooth communication, etc. The first device 102 and the second device 104 can be, but not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0034] With the widespread application of Bluetooth devices in the field of wireless communications, the transmission power control of Bluetooth devices has become particularly important. The Bluetooth master device and the slave device are paired and connected to be able to send and receive data packets. In traditional technology, the received signal strength indication (RSSI) of the received data packet is mainly used to determine whether Bluetooth transmission power compensation is required. However, since the transmission and reception of data packets requires interaction between the Bluetooth master and slave devices, the method of compensating Bluetooth transmission power through the RSSI of the data packet cannot ensure the response speed of Bluetooth power compensation. The transmission and reception of data packets will also increase the power consumption of the Bluetooth device. Moreover, the RSSI of the data packet is easily affected by the environment and varies greatly, and it is impossible to accurately compensate the transmission power of the Bluetooth device. Since current electronic devices support WiFi's 2.4GHz communication and Bluetooth communication, and the WiFi's 2.4GHz communication frequency band is the same as the working frequency band of Bluetooth communication, the CSI estimation of the Bluetooth communication channel can be achieved through WiFi's 2.4GHz channel state information (CSI). Based on this, the present application proposes a method for compensating Bluetooth transmit power, which uses the 2.4GHz CSI of WiFi communication to estimate the CSI of the Bluetooth communication channel to compensate for the Bluetooth transmit power, thereby improving the accuracy of Bluetooth transmit power compensation.

[0035] In one embodiment, Figure 2 As shown, a method for compensating Bluetooth transmission power is provided, and the method is applied to Figure 1 Taking the first device in the example as an example, the method includes the following steps:

[0036] S201: Acquire first channel state information of a WiFi communication channel used for performing wireless fidelity WiFi communication with a second device.

[0037] Among them, Wireless Fidelity (WiFi) is a technology that connects terminals to each other wirelessly. WiFi signals are transmitted through radio waves. 2.4G and 5G are two different frequency bands, and WiFi signals are transmitted within such frequency bands. It should be noted that in this application, the compensation for Bluetooth transmission power is achieved by using the same principle as the 2.4GHz communication frequency band of WiFi and the working frequency band of Bluetooth communication. Therefore, the transmission frequency band of the WiFi signal in the embodiment of the present application is the 2.4G frequency band.

[0038] Channel State Information (CSI) is a channel property of a communication link. It describes the attenuation factor of a signal on each transmission path. CSI can adapt the communication system to the current channel conditions and provide a guarantee for high-reliability and high-speed communication in a multi-antenna system.

[0039] In this embodiment, after the first device establishes a WiFi communication connection with the second device, the first device can measure the WiFi communication channel used for WiFi communication with the second device to obtain first channel state information of the WiFi communication channel used for WiFi communication with the second device, or the first device can send a measurement indication to the second device, instructing the second device to send the first channel state information of the WiFi communication channel used for WiFi communication with the first device to the first device.

[0040] S202: Acquire second channel state information of the Bluetooth communication channel according to the first channel state information.

[0041] Among them, Bluetooth is a short-range wireless communication technology with 79 frequency bands. The operating frequency range is 2402-2480MHZ. The transmission distance is usually about 10 meters. The Bluetooth communication channel in this embodiment is the path for Bluetooth data transmission.

[0042] In this embodiment, the principle that the 2.4 GHz communication frequency band of WiFi and the working frequency band of Bluetooth communication are the same can be used to map the first channel state information of the WiFi communication channel to the Bluetooth communication channel to obtain the second channel state information of the Bluetooth communication channel. Optionally, in this embodiment, according to the mapping relationship between the WiFi communication channel and the Bluetooth communication channel, the first channel state information of the WiFi communication channel can be mapped to the Bluetooth communication channel to obtain the second channel state information of the Bluetooth communication channel.

[0043] S203: Determine a compensation value of the Bluetooth transmission power according to the second channel state information, and compensate the Bluetooth transmission power according to the compensation value.

[0044] Since the second channel status information of the Bluetooth communication channel can reflect the quality of the Bluetooth communication channel, in this embodiment, the compensation value of the Bluetooth transmission power can be determined based on the second channel status information of the Bluetooth communication channel. As an optional implementation, the first device can determine the compensation value of the Bluetooth transmission power based on the status information of the Bluetooth communication channel in the case of no interference with the second device Bluetooth communication and the above-mentioned second channel status information. Alternatively, as another optional implementation, the first device can also determine the compensation value of the Bluetooth transmission power based on the channel status information corresponding to the standard Bluetooth transmission power and the above-mentioned second channel status information.

[0045] Further, after determining the compensation value of the Bluetooth transmission power, the first device may compensate the Bluetooth transmission power according to the determined compensation value, and use the compensated Bluetooth transmission power to perform Bluetooth communication with the second device.

[0046] In the above-mentioned Bluetooth transmission power compensation method, the first device can accurately obtain the first channel state information of the WiFi communication channel used for WiFi communication with the second device. Since the 2.4G frequency band of the wireless fidelity WiFi network is the same as the frequency band of the Bluetooth communication, the second channel state information of the Bluetooth communication channel can be accurately obtained based on the first channel state information obtained with higher accuracy. Then, the compensation value of the Bluetooth transmission power can be accurately determined based on the second channel state information of the Bluetooth communication channel, and the Bluetooth transmission power can be compensated with higher accuracy based on the determined compensation value of the Bluetooth transmission power, thereby improving the accuracy of the Bluetooth transmission power compensation.

[0047] In this embodiment, the process of obtaining the second channel state information of the Bluetooth communication channel according to the first channel state information of the WiFi communication channel is described in detail. In one embodiment, the above S202 includes: step A, mapping the first channel state information according to the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel to obtain the second channel state information.

[0048] Among them, the frequency range of the 2.4GHz frequency band of WiFi communication is 2.4~2.4835GHz, which is divided into 14 partially overlapping wireless carrier channels. That is to say, in this embodiment, the first frequency range can be any frequency range of 2.4~2.4835GHz, and the working frequency band of Bluetooth communication is also 2.4GHz, and the frequency range is also 2.4~2.4835GHz, that is, the second frequency range in this embodiment can also be any frequency range of 2.4~2.4835GHz.

[0049] Optionally, in this embodiment, the first channel state information of the WiFi communication channel can be directly mapped to the second channel state information of the Bluetooth communication channel according to the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel; or, the first channel state information of the WiFi communication channel can be mapped according to the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel, and the mapping value of the first channel state information of the WiFi communication channel can be compensated according to a preset channel compensation value to obtain the second channel state information of the Bluetooth communication channel.

[0050] In this embodiment, according to the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel, the process of mapping the first channel state information of the WiFi communication channel is relatively simple, the amount of calculation is small, and the second channel state information of the Bluetooth communication channel can be obtained relatively quickly, thereby improving the efficiency of obtaining the second channel state information of the Bluetooth communication channel.

[0051] In the above scenario where the first channel state information of the WiFi communication channel is mapped based on the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel to obtain the second channel state information of the Bluetooth communication channel, the first channel state information can be mapped based on the difference between the first frequency range and the second frequency range to obtain the second channel state information of the Bluetooth communication channel. In one embodiment, the above step A includes:

[0052] Step B: If the difference between the first frequency range and the second frequency range is less than a preset difference threshold, the first channel state information is used as the second channel state information.

[0053] In this embodiment, if the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is less than the preset difference threshold, it means that the first frequency range of the WiFi communication channel is relatively close to the second frequency range of the Bluetooth communication channel, the difference value is small, and the channel state information of the two is also relatively close, then the first channel state information of the WiFi communication channel can be directly used as the second channel state information of the Bluetooth communication channel.

[0054] In this embodiment, if the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is less than the preset difference threshold, it means that the channel state information of the WiFi communication channel and the channel state information of the Bluetooth communication channel are relatively close, and the first channel state information of the WiFi communication channel can be directly used as the second channel state information of the Bluetooth communication channel. The determination process is relatively simple and the amount of calculation is small, ensuring that the second channel state information of the Bluetooth communication channel can be obtained in a timely manner.

[0055] In another embodiment, the above step A comprises:

[0056] Step C: If the difference between the first frequency range and the second frequency range is greater than or equal to a preset difference threshold, a channel state compensation value is determined according to the difference between the first frequency range and the second frequency range, and the first channel state information is compensated according to the channel state compensation value to obtain the second channel state information.

[0057] In this embodiment, if the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is greater than or equal to the preset difference threshold, it means that the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is large, and the difference between the channel state information of the WiFi communication channel and the state information of the Bluetooth communication channel is also large. At this time, the channel compensation value can be determined according to the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel. For example, the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel can be directly determined as the channel state compensation value, or the channel compensation value can be determined according to the correspondence between the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel and the channel state compensation value. Further, the first channel state information of the WiFi communication channel can be compensated according to the determined channel compensation value, and the state information after compensation is determined as the second channel state information of the Bluetooth communication channel.

[0058] In this embodiment, if the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is greater than or equal to a preset difference threshold, it means that the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is large. At this time, the channel state compensation value is first determined according to the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel, and then the first channel state information is compensated according to the determined channel state compensation value. The relatively accurate channel state information obtained can be determined as the second channel state information of the Bluetooth communication channel, thereby improving the accuracy of the obtained second channel state information of the Bluetooth communication channel.

[0059] In the above scenario where the compensation value of the Bluetooth transmission power is determined based on the second channel state information of the Bluetooth communication channel, the compensation value of the Bluetooth transmission power can be determined based on the second channel state information of the Bluetooth communication channel and the channel threshold when the Bluetooth communication channel is free of interference. In one embodiment, the above S203 includes: determining the compensation value based on the second channel state information and a preset channel threshold, where the channel threshold is obtained when the Bluetooth communication channel is free of interference.

[0060] Among them, the preset channel threshold is obtained by measuring the Bluetooth communication channel when there is no interference in the Bluetooth communication channel. As an optional implementation, the difference between the second channel state information of the Bluetooth communication channel and the preset channel threshold can be determined as the compensation value of the Bluetooth transmission power; or, as another optional implementation, the ratio of the second channel state information of the Bluetooth communication channel to the preset channel threshold can be determined as the compensation value of the Bluetooth transmission power. Since the compensation value compensates for the Bluetooth transmission power, and the difference between the second channel state information of the Bluetooth communication channel and the preset channel threshold represents the difference between the second channel state information of the Bluetooth communication channel and the channel state information of the Bluetooth communication channel in the absence of interference, therefore, in this embodiment, as a preferred implementation, the difference between the second channel state information of the Bluetooth communication channel and the preset channel threshold can be determined as the compensation value of the Bluetooth transmission power.

[0061] In this embodiment, since the process of determining the compensation value of the Bluetooth transmission power is relatively simple based on the second channel state information of the Bluetooth communication channel and the preset channel threshold, the compensation value of the Bluetooth transmission power can be determined relatively quickly, thereby improving the efficiency of determining the compensation value of the Bluetooth transmission power.

[0062] It can be understood that the Bluetooth communication channel includes multiple Bluetooth communication channels, and therefore, the acquired second channel state information of the Bluetooth communication channel may be the second channel state information of multiple Bluetooth communication channels. In this embodiment, the Bluetooth communication channel is multiple Bluetooth communication channels, and the above S202 includes: acquiring the second channel state information of each Bluetooth communication channel according to the first channel state information.

[0063] Typically, a Bluetooth communication channel includes multiple Bluetooth communication channels. Therefore, the above-mentioned Bluetooth communication channel may include multiple Bluetooth communication channels, and the determined second channel state information of the Bluetooth communication channel is also the second channel state information of the multiple Bluetooth communication channels. That is to say, in this embodiment, the second channel state information of each Bluetooth communication channel in the multiple Bluetooth communication channels can be obtained according to the first channel state information of the WiFi communication channel, so as to obtain the second channel state information of each Bluetooth communication channel.

[0064] In this embodiment, the second channel state information of each Bluetooth communication channel in the plurality of Bluetooth communication channels can be acquired according to the first channel state information of the WiFi communication channel, thereby ensuring the integrity of the acquired second channel state information of the Bluetooth communication channel.

[0065] When performing Bluetooth communication, not all Bluetooth communication channels may be in use, but some Bluetooth communication channels may be in use. Therefore, in the above scenario where the Bluetooth transmission power is compensated according to the compensation value of the Bluetooth transmission power, the compensation may be performed on the Bluetooth transmission power of the used Bluetooth communication channels. Figure 3 As shown, the above S203 includes:

[0066] S301, determining a target Bluetooth communication channel used by current Bluetooth communication; the target Bluetooth communication channel is any one of a plurality of Bluetooth communication channels.

[0067] The Bluetooth communication channel used for Bluetooth communication may be part of the multiple Bluetooth communication channels, so in this embodiment, the first device can determine the target Bluetooth communication channel used for the current Bluetooth communication from the multiple Bluetooth communication channels. Optionally, the target Bluetooth communication channel in this embodiment can be one of the multiple Bluetooth communication channels, or multiple Bluetooth communication channels in the multiple Bluetooth communication channels, which is not limited in this embodiment.

[0068] S302: Compensate the Bluetooth transmission power of the target Bluetooth communication channel according to the compensation value of the target Bluetooth communication channel.

[0069] In this embodiment, after the first device determines the target Bluetooth communication channel used for the current Bluetooth communication, it can determine the compensation value of the target Bluetooth communication channel based on the compensation value of the Bluetooth communication channel determined above, and then compensate the Bluetooth transmission power of the target Bluetooth communication channel according to the determined compensation value of the target Bluetooth communication channel, and use the compensated Bluetooth transmission power for Bluetooth communication.

[0070] In this embodiment, the first device can determine the target Bluetooth communication channel used for Bluetooth communication from multiple Bluetooth communication channels. Since the determined target Bluetooth communication channel is the Bluetooth communication channel used for Bluetooth communication, when compensating the transmission power of the Bluetooth communication channel, the transmission power compensation is performed on the Bluetooth communication channel used for Bluetooth communication, rather than compensating the transmission power of all Bluetooth communication channels. This reduces the power consumption of the first device caused by compensating the transmission power of other Bluetooth communication channels, and reduces the power consumption of the first device while ensuring the compensation of the Bluetooth transmission power of the Bluetooth communication channel used for Bluetooth communication.

[0071] In the above scenario of obtaining the first channel state information of the WiFi communication channel used for WiFi communication with the second device, it is necessary to first establish WiFi communication between the first device and the second device. In one embodiment, Figure 4 As shown, the above method also includes:

[0072] S401, receiving a hotspot activation instruction triggered by a user.

[0073] In this embodiment, since it is necessary to obtain the first channel state information of the WiFi communication channel used by the first device and the second device for WiFi communication, it is necessary to first ensure that WiFi communication is established between the first device and the second device. As an optional implementation, the user can trigger a hotspot opening instruction in the first device, and establish WiFi communication with the second device through the hotspot opening instruction. Optionally, the user can trigger the hotspot opening instruction through voice, or can also trigger the hotspot opening instruction through a triggering operation, etc. This embodiment does not limit the way in which the user triggers the hotspot opening instruction.

[0074] S402, in response to the hotspot opening instruction, establish WiFi communication with the second device.

[0075] In this embodiment, the first device can respond to the received hotspot activation instruction, turn on the personal hotspot switch of the first device, share its own mobile network or the connected wireless local area network (Wireless Local Area Networks, WLAN) with the second device in the form of a hotspot, and establish WiFi communication with the second device.

[0076] In this embodiment, the first device receives a hotspot activation instruction triggered by a user, and by responding to the hotspot activation instruction, the process of establishing WiFi communication with the second device is relatively simple and does not involve complicated operations. This enables the first device to quickly establish WiFi communication with the second device, thereby improving the efficiency of establishing WiFi communication between the two devices.

[0077] In the above scenario of obtaining the first channel state information of the WiFi communication channel used for WiFi communication with the second device, the first device can obtain the first channel state information of the WiFi communication channel used for WiFi communication between the first device and the second device by sending a detection signal to the second device. Figure 5 As shown, the above S201 includes:

[0078] S501, sending a WiFi communication channel detection signal to a second device.

[0079] In this embodiment, the first device can send a WiFi communication channel detection signal to the second device through the WiFi communication connection between the first device and the second device, so that the second device can detect the WiFi communication channel used for WiFi communication between the first device and the second device based on the WiFi communication channel detection signal, and obtain the first channel status information of the WiFi communication channel used.

[0080] S502: Receive first channel state information sent by a second device based on a WiFi communication channel detection signal.

[0081] In this embodiment, after the second device receives the WiFi communication channel detection signal sent by the first device and responds to the WiFi communication channel detection signal, the second device can obtain the first channel state information of the WiFi communication channel used for WiFi communication between the first device and the second device, and then the second device can send the obtained first channel state information to the first device based on the WiFi communication channel detection signal, so that the first device obtains the first channel state information of the WiFi communication channel used for WiFi communication between the first device and the second device.

[0082] In this embodiment, the first device sends a WiFi communication channel detection signal to the second device, so that the second device responds to the WiFi communication channel detection signal and accurately detects the first channel state information of the WiFi communication channel used for WiFi communication between the first device and the second device, thereby sending the acquired first channel state information to the first device, so that the first device can obtain first channel state information with higher accuracy.

[0089] S6, if the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel is greater than or equal to a preset difference threshold, a channel state compensation value is determined according to the difference between the first frequency range of the WiFi communication channel and the second frequency range of the Bluetooth communication channel, and the first channel state information is compensated according to the channel state compensation value to obtain the second channel state information of the Bluetooth communication channel.
