[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] It should be understood that the "embodiments of the present application" or "the aforementioned embodiments" mentioned throughout the specification mean that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in the embodiments of the present application" or "in the aforementioned embodiments" appearing throughout the specification may not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. In the various embodiments of the present application, the size of the sequence number of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. The above-mentioned sequence numbers of the embodiments of the present application are for description only and do not represent the advantages and disadvantages of the embodiments.

[0025] The present application provides a signal transmission method for electronic equipment. Figure 1 As shown, the method comprises the following steps:

[0026] Step 101: When a first antenna of an electronic device receives a first radio frequency signal and transmits a second radio frequency signal, a first signal-to-noise ratio of the first radio frequency signal is obtained.

[0027] There is an overlap between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.

[0028] In the embodiment of the present application, the receiving frequency range of the first radio frequency signal includes 880 MHz to 915 MHz, and the transmitting frequency range of the second radio frequency signal includes 869 MHz to 894 MHz.

[0029] In the embodiment of the present application, the radio frequency signal is a modulated radio wave with a certain transmission frequency. The first radio frequency signal may be a signal whose signal frequency is received by the electronic device through the first antenna in the downlink frequency band of NR Band 5, and the second radio frequency signal may be a signal whose signal frequency is transmitted by the electronic device to the base station through the first antenna in the uplink frequency band of NR Band 8. Of course, the first radio frequency signal may also be a signal whose signal frequency is received by the electronic device through the first antenna in the downlink frequency band corresponding to the first frequency band number, and the second radio frequency signal may be a signal whose signal frequency is transmitted by the electronic device to the base station through the first antenna in the uplink frequency band corresponding to the second frequency band number; it should be emphasized that the first frequency band number and the second frequency band number are frequency band numbers under the same mobile communication technology, the first frequency band number is different from the second frequency band number, and there is an overlapping part between the downlink frequency band corresponding to the first frequency band number and the uplink frequency band corresponding to the second frequency band number.

[0030] Here, the downlink frequency band can be understood as the channel frequency band for electronic devices to send radio frequency signals to base stations, and the uplink frequency band can be understood as the channel frequency band for base stations to send signals to electronic devices. It should be noted that there is no overlapping part between the uplink frequency band and the downlink frequency band corresponding to the same frequency band number, and there may be overlapping parts between the uplink frequency band and the downlink frequency band corresponding to different frequency band numbers. Exemplarily, the electronic device supports but is not limited to the following NR frequency band numbers, namely NR Band 1, NR Band 3, NR Band 5, NR Band 8, NR Band 28, and NR Band 78; wherein, the frequency band represented by the NR frequency band number can refer to the 3rd Generation Partnership Project (3GPP) 38.104 protocol. Among them, the uplink frequency band of NR Band 5 is 824 MHz to 829 MHz, and the downlink frequency band of NR Band 5 is 869 MHz to 894 MHz; the uplink frequency band of NR Band 8 is 880 MHz to 915 MHz, and the downlink frequency band of NR Band 8 is 925 MHz to 860 MHz; there is no overlapping part between the uplink frequency band and the downlink frequency band corresponding to NR Band 5, and there is no overlapping part between the uplink frequency band and the downlink frequency band corresponding to NR Band 8; but there is an overlapping part between the downlink frequency band corresponding to NR Band 5 and the uplink frequency band corresponding to NR Band 8, and there is no overlapping part between the uplink frequency band corresponding to NR Band 5 and the downlink frequency band corresponding to NR Band 8.

[0031] In the embodiment of the present application, the signal-to-noise ratio (SNR or S / N) refers to the ratio of the power of the radio frequency signal to the power of the noise in the electronic device or electronic system. The signal-to-noise ratio is used to determine whether the quality of the first radio frequency signal meets the quality condition; if the signal-to-noise ratio is within the signal-to-noise ratio threshold range, it is determined that the quality of the received first radio frequency signal meets the quality condition, and there is no need to adjust the transmission power of the second radio frequency signal; if the signal-to-noise ratio is not within the signal-to-noise ratio threshold range, it is determined that the quality of the received first radio frequency signal does not meet the quality condition, and the transmission power of the second radio frequency signal needs to be adjusted to reduce the noise generated by the second radio frequency signal on the first radio frequency signal.

[0032] Here, the radio frequency signal refers to an electronic signal from outside the electronic device that needs to be processed by the electronic device, and noise refers to another radio frequency signal emitted by the electronic device while receiving a radio frequency signal, or an irregular additional signal that does not exist in the original signal after passing through the electronic device, and this signal does not change with the change of the original signal. Here, the signal-to-noise ratio is also called the signal-to-noise ratio. It should be noted that when the electronic device receives a first radio frequency signal through a first antenna and transmits a second radio frequency signal through the first antenna, the second radio frequency signal at this time is noise relative to the first radio frequency signal.

[0033] In an embodiment of the present application, the electronic device has a dual SIM dual active (DSDA) function, and the electronic device is configured with at least two identification cards. Dual SIM dual active means that the electronic device can not only reside in a network to which multiple identification cards belong at the same time, but also communicate in a network to which multiple identification cards belong at the same time; the identification card can be a subscriber identity module (SIM) card in the electronic device. It should be noted that the two identification cards of the electronic device can both work under the 5G standard, and the radio frequency signal of each identification card can only be received or transmitted through one antenna.

[0034] In practical applications, electronic devices include but are not limited to mobile phones, tablet computers, laptops, personal digital assistants (PDAs), wearable devices, vehicle-mounted devices and other mobile terminal devices.

[0035] In an embodiment of the present application, when the electronic device receives a first radio frequency signal corresponding to a first frequency band identifier through a first antenna, the electronic device transmits a second radio frequency signal corresponding to a second frequency band identifier through the first antenna, and there is an overlapping part between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal. At this time, the electronic device obtains a first signal-to-noise ratio of the first radio frequency signal, so that the electronic device determines whether the quality of the received first radio frequency signal meets the quality requirement according to the first signal-to-noise ratio.

[0036] Step 102: If the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the first radio frequency signal is received at a constant receiving power through the first antenna, and a second radio frequency signal is transmitted at a reduced transmitting power through an antenna selected from the first antenna and a second antenna of the electronic device.

[0037] The reduced transmission power is used to reduce the noise generated by the second radio frequency signal on the first radio frequency signal to improve the first signal-to-noise ratio.

[0038] In the embodiment of the present application, the signal-to-noise ratio threshold range is a range of the signal-to-noise ratio when the quality of the first radio frequency signal received by the electronic device meets the quality requirement.

[0039] In the embodiment of the present application, the constant received power may be understood as the output power of the received first radio frequency signal not changing.

[0040] In an embodiment of the present application, the electronic device includes at least two antennas, namely a first antenna and a second antenna. Here, when the electronic device receives a first radio frequency signal with a constant receiving power through the first antenna, the electronic device can select the first antenna to continue to transmit the second radio frequency signal with a reduced transmission power. Of course, the electronic device can also select the second antenna to continue to transmit the second radio frequency signal with a reduced transmission power.

[0041] In an embodiment of the present application, in a process in which a first antenna of an electronic device receives a first radio frequency signal and the first antenna transmits a second radio frequency signal, a first signal-to-noise ratio of the first radio frequency signal is obtained, and it is determined whether the first signal-to-noise ratio is within a signal-to-noise ratio threshold range; if the electronic device determines that the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the electronic device determines that the quality of the currently received first radio frequency signal does not meet the quality condition, and adjusts the transmit power of the second radio frequency signal to obtain a reduced transmit power; finally, the first radio frequency signal is received at a constant receive power through the first antenna, and the second radio frequency signal is transmitted at a reduced transmit power through an antenna selected from the first antenna and the second antenna of the electronic device, thereby reducing the noise generated by the second radio frequency signal on the first radio frequency signal and improving the first signal-to-noise ratio.

[0042] A signal transmission method provided by an embodiment of the present application obtains a first signal-to-noise ratio of a first radio frequency signal by receiving a first radio frequency signal through a first antenna of an electronic device and transmitting a second radio frequency signal through the first antenna; wherein the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal have an overlapping part; if the first signal-to-noise ratio is not within a signal-to-noise ratio threshold range, the first radio frequency signal is received through the first antenna at a constant receiving power, and the second radio frequency signal is transmitted through a selected antenna from the first antenna and the second antenna of the electronic device at a reduced transmitting power; wherein the reduced transmitting power is used to reduce the noise generated by the second radio frequency signal on the first radio frequency signal to improve the first signal-to-noise ratio; in this way, by reducing the transmitting power of the second radio frequency signal, the noise generated by the second radio frequency signal on the first radio frequency signal is reduced, thereby improving the signal-to-noise ratio of the first radio frequency signal and improving the receiving performance of the first radio frequency signal.

[0043] The present application provides a signal transmission method for electronic equipment. Figure 2As shown, the method includes the following steps 201 to 202; or step 201, and steps 203 to 205:

[0044] Step 201: When a first antenna of an electronic device receives a first radio frequency signal and transmits a second radio frequency signal, a first signal-to-noise ratio of the first radio frequency signal is obtained.

[0045] There is an overlap between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.

[0046] Step 202: If the first signal-to-noise ratio is not within a signal-to-noise ratio threshold range, switch one of the first radio frequency signal and the second radio frequency signal transmitted by the first antenna to be transmitted by a second antenna whose distance from the first antenna is greater than or equal to a distance threshold.

[0047] In the embodiment of the present application, the distance threshold can be understood as the distance between the first antenna and the second antenna satisfying the distance condition. Here, the distance between the first antenna and the second antenna being greater than or equal to the distance threshold can be understood as the second RF signal transmitted by the second antenna will not generate noise to the first RF signal received by the first antenna, or the noise generated to the first RF signal is within an acceptable range.

[0048] In an embodiment of the present application, the electronic device receives a first radio frequency signal through a first antenna, and in the process of transmitting a second radio frequency signal through the first antenna, obtains a first signal-to-noise ratio of the first radio frequency signal, and determines whether the first signal-to-noise ratio is within a signal-to-noise ratio threshold range; if the electronic device determines that the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the electronic device determines that the quality of the currently received first radio frequency signal does not meet the quality condition; further, the electronic device can switch the first radio frequency signal received through the first antenna to be received by a second antenna whose distance from the first antenna is greater than or equal to the distance threshold; of course, the electronic device can also switch the second radio frequency signal transmitted through the first antenna to be transmitted by a second antenna whose distance from the first antenna is greater than or equal to the distance threshold; in this way, it is ensured that when the second antenna whose distance from the first antenna meets the distance requirement transmits the second radio frequency signal, the influence on the first radio frequency signal received through the first antenna is reduced to improve the signal-to-noise ratio of the first radio frequency signal, thereby improving the reception performance of the first radio frequency signal.

[0049] Step 203: If the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the second radio frequency signal transmitted by the first antenna is switched to be transmitted by a second antenna whose distance from the first antenna is less than the distance threshold.

[0050] In the embodiment of the present application, the distance between the first antenna and the second antenna being less than the distance threshold can be understood as the second RF signal transmitted by the second antenna will generate certain noise to the first RF signal received by the first antenna, and the noise generated to the first RF signal is within an unacceptable range. It should be noted that when the electronic device transmits the second RF signal through the second antenna whose distance from the first antenna is less than the distance threshold, the noise generated to the first RF signal received by the first antenna must be less than the noise generated to the first RF signal received by the first antenna when the electronic device transmits the second RF signal and receives the first RF signal on the same antenna, i.e., the first antenna.

[0051] In an embodiment of the present application, the electronic device receives a first radio frequency signal through a first antenna, and in the process of transmitting a second radio frequency signal through the first antenna, obtains a first signal-to-noise ratio of the first radio frequency signal, and determines whether the first signal-to-noise ratio is within a signal-to-noise ratio threshold range; if the electronic device determines that the signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the electronic device determines that the quality of the currently received first radio frequency signal does not meet the quality condition; further, the electronic device can switch the second radio frequency signal transmitted through the first antenna to be transmitted by a second antenna whose distance from the first antenna is less than the distance threshold.

[0052] Step 204: Obtain a second signal-to-noise ratio of the first radio frequency signal.

[0053] Step 205: If the second signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the first RF signal is received at a constant receiving power through the first antenna, and the second RF signal is transmitted at a reduced transmitting power through the second antenna.

[0054] In an embodiment of the present application, the electronic device determines that the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, switches the second RF signal transmitted by the first antenna to be transmitted by the second antenna whose distance from the first antenna is less than the distance threshold, and then continues to obtain the second signal-to-noise ratio of the first RF signal at the current moment, and determines whether the second signal-to-noise ratio is within the signal-to-noise ratio threshold range; if the electronic device determines that the second signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the electronic device determines that the quality of the currently received first RF signal still does not meet the quality condition, and adjusts the transmit power of the second RF signal to obtain the reduced transmit power; finally, the first RF signal is received by the first antenna at a constant receive power, and the second RF signal is continuously transmitted by the second antenna at the reduced transmit power, thereby reducing the noise generated by the second RF signal on the first RF signal and improving the first signal-to-noise ratio; in this way, when the second RF signal is transmitted by the second antenna whose distance from the first antenna is less than the distance threshold, and the second RF signal still affects the first RF signal received by the first antenna, the transmit power of the second RF signal is continuously adjusted to reduce the influence of the second RF signal on the first RF signal to improve the signal-to-noise ratio of the first RF signal, thereby improving the reception performance of the first RF signal.

[0055] In a feasible application scenario, refer to Figure 3 As shown, Figure 3 The structure diagram of the antenna is shown; taking the NR band numbers of the NR bands supported by the electronic device as NR Band 5 and NR Band 8 as an example, before the electronic device switches the antenna (Antenna, ANT), since the electronic device does not transmit the second RF signal with a frequency in the working frequency band corresponding to NR Band 8, the electronic device can receive and transmit the first RF signal with a frequency in the working frequency band corresponding to NR Band 5 through the first antenna ANT1, and receive the second RF signal with a frequency in the working frequency band corresponding to NR Band 8 through the third antenna ANT0, and there is no overlapping part between the uplink frequency band corresponding to NR Band 5 and the downlink frequency band corresponding to NR Band 8, so there is no need to switch the antenna. Among them, the first antenna is a device of the primary receiver chain (PRX) in the low frequency band (LB); the third antenna is a device of the diversity receiver chain (DRX) in the low frequency band LB; the second antenna is a device of another primary receiver chain PRX in the low frequency band LB.

[0056] When the electronic device needs to transmit a second RF signal with a frequency in the working frequency band corresponding to NR Band 8 through the first antenna, there may be a situation where the first antenna of the electronic device receives the first RF signal and the first antenna transmits the second RF signal. Since there is an overlapping part between the downlink frequency band corresponding to NR Band 5 and the uplink frequency band corresponding to NR Band 8, the electronic device needs to switch the antenna. Through the embodiment of the present application, the electronic device switches the antenna, that is, the first antenna receives the first RF signal with a constant receiving power, and transmits the second RF signal with a reduced transmitting power through the first antenna and one of the antennas selected from the second antenna of the electronic device. It should be noted that after the electronic device switches the antenna, the first antenna is a device of the main set receiving path PRX in the low frequency band LB, and the first antenna is used to receive the first RF signal with a frequency in the working frequency band corresponding to NR Band 5; the third antenna is a device of the diversity receiving path DRX in the low frequency band; the second antenna is a device of another main set receiving path PRX in the low frequency band LB, and the second antenna is used to transmit and receive the second RF signal with a frequency in the working frequency band corresponding to NR Band 8. In this way, by switching the antenna, the influence of the second radio frequency signal on the first radio frequency signal is mitigated to improve the signal-to-noise ratio of the first radio frequency signal, thereby improving the receiving performance of the first radio frequency signal.

[0057] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0058] The present application provides a signal transmission method for electronic equipment. Figure 4 As shown, the method comprises the following steps:

[0059] Step 401: When a first antenna of an electronic device receives a first radio frequency signal and transmits a second radio frequency signal, a first signal-to-noise ratio of the first radio frequency signal is obtained.

[0060] There is an overlap between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.

[0061] Step 402: If the first signal-to-noise ratio is not within a signal-to-noise ratio threshold range, obtain a transmit power of a second radio frequency signal.

[0062] In the embodiment of the present application, the transmission power refers to the signal strength of the radio frequency signal transmitted by the electronic device. There is a correlation between the transmission power and the transmission distance of the radio frequency signal, that is, the greater the transmission power, the longer the transmission distance of the radio frequency signal, and the smaller the transmission power, the shorter the transmission distance of the radio frequency signal.

[0063] Step 403: sequentially reduce the transmission power with an adjustment step size, receive the first RF signal with a constant reception power through the first antenna, and transmit the second RF signal with the transmission power reduced each time through an antenna selected from the first antenna and the second antenna of the electronic device.

[0064] In an embodiment of the present application, when the electronic device determines that the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, it obtains the transmission power of the second radio frequency signal and adjusts the transmission power, that is, the transmission power is sequentially reduced by adjusting the step size to obtain the transmission power after each reduction; thereafter, when the electronic device receives the first radio frequency signal through the first antenna with a constant receiving power, it can select the first antenna to continue to transmit the second radio frequency signal with the transmission power reduced each time, and can also select the second antenna to continue to transmit the second radio frequency signal with the transmission power reduced each time; in this way, by reducing the transmission power of the second radio frequency signal, the noise generated by the second radio frequency signal on the first radio frequency signal is reduced to improve the signal-to-noise ratio of the first radio frequency signal, thereby improving the reception performance of the first radio frequency signal.

[0065] In the embodiment of the present application, step 403 sequentially reduces the transmit power with an adjustment step size, receives the first radio frequency signal with a constant receive power through the first antenna, and transmits the second radio frequency signal with the transmit power reduced each time through the first antenna and one antenna selected from the second antenna of the electronic device, which can be implemented by the following steps:

[0066] The transmission power is reduced with an adjustment step size until, in the process of receiving the first radio frequency signal at a constant reception power through the first antenna, it is determined that when the second radio frequency signal is transmitted at the reduced transmission power through the first antenna and one antenna selected from the second antenna of the electronic device, the signal-to-noise ratio of the first radio frequency signal is within a signal-to-noise ratio threshold range, and the reduction of the transmission power of the second radio frequency signal is stopped.

[0067] In the embodiment of the present application, the determination of the reduced transmit power may be that the electronic device adjusts the transmit power of the second radio frequency signal once to obtain the reduced transmit power that satisfies the condition, or that the electronic device adjusts the transmit power of the second radio frequency signal multiple times to obtain the reduced transmit power that satisfies the condition. In other words, the present application does not specifically limit the number of adjustment cycles, and the reduced transmit power that satisfies the condition shall prevail.

[0068] Here, if the reduced transmission power is obtained after the electronic device adjusts the transmission power of the second radio frequency signal once, the specific implementation process is as follows:

[0069] First, the electronic device reduces the transmission power for the first time with an adjustment step size to obtain the first reduced transmission power; secondly, the electronic device obtains the third signal-to-noise ratio of the first radio frequency signal when the second radio frequency signal is transmitted with the first reduced transmission power; thirdly, the electronic device determines that the third signal-to-noise ratio is within the signal-to-noise ratio threshold range, receives the first radio frequency signal with a constant receiving power through the first antenna, and transmits the second radio frequency signal with the first reduced transmission power through an antenna selected from the first antenna and the second antenna of the electronic device; finally, the electronic device stops reducing the transmission power of the second radio frequency signal. In this way, the electronic device reduces the noise generated by the second radio frequency signal on the first radio frequency signal by reducing the transmission power of the second radio frequency signal once, thereby improving the signal-to-noise ratio of the first radio frequency signal and improving the reception performance of the first radio frequency signal.

[0070] Here, if the reduced transmission power is obtained after the electronic device adjusts the transmission power of the second radio frequency signal at least twice, the specific implementation process is as follows:

[0071] First, the electronic device reduces the transmission power for the first time with the adjustment step size to obtain the first reduced transmission power; secondly, the electronic device obtains the third signal-to-noise ratio of the first radio frequency signal when the second radio frequency signal is transmitted with the first reduced transmission power; thirdly, the electronic device determines that the third signal-to-noise ratio is not within the signal-to-noise ratio threshold range, and continues to reduce the first reduced transmission power again with the adjustment step size to obtain the second reduced transmission power; then, the electronic device obtains the fourth signal-to-noise ratio of the first radio frequency signal when the second radio frequency signal is transmitted with the second reduced transmission power; thereafter, the electronic device determines that the fourth signal-to-noise ratio is within the signal-to-noise ratio threshold range, receives the first radio frequency signal with a constant receiving power through the first antenna, and transmits the second radio frequency signal with the second reduced transmission power through one antenna selected from the first antenna and the second antenna of the electronic device; finally, the electronic device stops reducing the transmission power of the second radio frequency signal. In this way, the electronic device reduces the noise generated by the second radio frequency signal on the first radio frequency signal by reducing the transmission power of the second radio frequency signal twice, thereby improving the signal-to-noise ratio of the first radio frequency signal and improving the reception performance of the first radio frequency signal.

[0072] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0073] The present application provides a signal transmission method for electronic equipment. Figure 5 As shown, the method comprises the following steps:

[0074] Step 501: When a first antenna of an electronic device receives a first radio frequency signal and transmits a second radio frequency signal, a first signal-to-noise ratio of the first radio frequency signal is obtained.

[0075] There is an overlap between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.

[0076] Step 502: Obtain a relationship mapping table corresponding to a selected antenna.

[0077] The relationship mapping table includes a mapping relationship between the signal-to-noise ratio of the first radio frequency signal and the transmit power of the second radio frequency signal.

[0078] In an embodiment of the present application, the relationship mapping table is used to determine the transmission power of the second RF signal corresponding to the signal-to-noise ratio of the first RF signal when the signal-to-noise ratio of the first RF signal is not within the signal-to-noise ratio threshold range, and when the second RF signal is transmitted at the transmission power, the signal-to-noise ratio of the currently received first RF signal is within the signal-to-noise ratio threshold range. Here, the relationship mapping table includes a first relationship mapping table corresponding to the first antenna, and a second relationship mapping table corresponding to the second antenna, and the first relationship mapping table and the second relationship mapping table are different.

[0079] It should be noted that the electronic device selects different antennas and obtains different relationship mapping tables, that is, when the electronic device receives a first RF signal and transmits a second RF signal on the same antenna, and when the electronic device receives the first RF signal on the first antenna and transmits the second RF signal on the second antenna, the signal-to-noise ratio of the same first RF signal corresponds to a different transmission power of the second RF signal.

[0080] Step 503: Search the relationship mapping table for a transmit power corresponding to the first signal-to-noise ratio as the reduced transmit power.

[0081] Step 504: Receive the first radio frequency signal at a constant receiving power through the first antenna, and transmit the second radio frequency signal at a reduced transmitting power through an antenna selected from the first antenna and a second antenna of the electronic device.

[0082] In an embodiment of the present application, first, the electronic device receives the first RF signal through the first antenna, and obtains the first signal-to-noise ratio of the first RF signal during the process of transmitting the second RF signal through the first antenna; secondly, the electronic device selects an antenna from the first antenna and the second antenna, and obtains a relationship mapping table corresponding to the selected antenna; then, the electronic device searches the selected relationship mapping table for the transmission power corresponding to the first signal-to-noise ratio, which is the reduced transmission power; finally, the electronic device receives the first RF signal through the first antenna at a constant receiving power, and transmits the second RF signal through the first antenna and the selected antenna from the second antenna of the electronic device at the reduced transmission power; in this way, the electronic device obtains the reduced transmission power of the second RF signal by looking up the table, and transmits the second RF signal through the selected antenna at the reduced transmission power, which not only reduces the noise generated by the second RF signal on the first RF signal, but also improves the signal-to-noise ratio of the first RF signal, thereby improving the receiving performance of the first RF signal.
