[0002] Currently, with the popularization of 5G communication technologies, people's communication experience is getting better and better. However, current electronic devices such as mobile phones require more and more antennas. As full-screen gradually becomes the mainstream, the available clearance space for antennas in electronic devices is getting less and less. Therefore, some antennas are set relatively close to each other, resulting in interference and a decline in the communication quality of the interfered antennas. Summary of the Invention

The detection and calculation unit is coupled with the second antenna and the radio frequency transceiver. The detection and calculation unit is used to detect the interference signal coupled from the first antenna to the second antenna when the first antenna transmits an electromagnetic wave signal, calculate the corresponding interference intensity value according to the detected interference signal, and send the interference intensity value to the radio frequency transceiver. Among them, the radio frequency transceiver is further used to carry the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna according to the interference intensity value, where the interference information at least includes the interference intensity value.

[0006] Third aspect, an electronic device is further provided. The electronic device includes a radio frequency system.

Thus, the base station can adjust the power of communicating with the second antenna according to the interference information carried in the received electromagnetic wave signal. For example, increasing the power of communicating with the second antenna can eliminate the interference. By detecting the interference signal coupled from the first antenna to the second antenna in real time when the first antenna transmits the electromagnetic wave signal, and calculating the corresponding interference intensity value according to the detected interference signal, therefore, the interference intensity value can accurately reflect the current real interference degree, and enable the base station to adjust the communication power to a more appropriate power according to the interference intensity value in the interference information.

In the present application, the term "connection" mainly refers to a physical structure connection without other explanations, and in the case of explanations, it may also include meanings such as electrical connection, direct connection or indirect connection. In the description of the embodiments of the present invention, the terms "first", "second", etc. are not specific, but are used to distinguish objects with the same name. In the case where the specification clearly states, the objects with the same name referred to by the terms "first", "second", etc. may be the same object.

[0020] Please refer to Figure 1 , which is a simple structural schematic diagram of the radio frequency module 1 in some embodiments of the present application. As Figure 1 shown, the radio frequency module 1 includes a radio frequency transceiver 11 and a detection and calculation unit 12. The radio frequency transceiver 11 is used to be coupled to at least the first antenna 2 and the second antenna 3, and receive or transmit electromagnetic wave signals of corresponding frequency bands through the first antenna and the second antenna. Among them, the frequency bands of the electromagnetic wave signals received or transmitted by the first antenna 2 and the second antenna 3 are different. The detection and calculation unit 12 is coupled to the second antenna 3 and the radio frequency transceiver 11. The detection and calculation unit 12 is used to detect the interference signal coupled from the first antenna 2 to the second antenna 3 when the first antenna 2 transmits an electromagnetic wave signal, calculate the corresponding interference intensity value according to the detected interference signal, and send the interference intensity value to the radio frequency transceiver 11. Among them, the radio frequency transceiver 11 is further used to carry the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna 3 according to the interference intensity value, where the interference information at least includes the interference intensity value.

[0021] Among them, in this application, when the first antenna 2 transmits an electromagnetic wave signal, the interference signal coupled from the first antenna 2 to the second antenna 3 is detected, and the corresponding interference intensity value is calculated based on the detected interference signal. The radio frequency transceiver 11 is further configured to carry the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna 3 according to the interference intensity value. Among them, the interference information at least includes the interference intensity value, so that the interference information corresponding to the current interference degree can be effectively reported. Thus, it can enable a base station (not shown in the figure) to adjust the communication power with the second antenna 3 according to the interference information carried in the received electromagnetic wave signal. For example, increasing the communication power with the second antenna 3 can eliminate this interference. Among them, since in this application, when the first antenna 2 transmits an electromagnetic wave signal, the interference signal coupled from the first antenna 2 to the second antenna 3 is detected in real time, and the corresponding interference intensity value is calculated based on the detected interference signal. Therefore, the interference intensity value can accurately reflect the current actual interference degree, and it can enable the base station to adjust the communication power to a more appropriate power according to the interference intensity value in the interference information. Compared with some existing methods that fixedly carry the maximum interference intensity value to enable the base station to increase the communication power to the greatest extent, this application can effectively save energy consumption.

[0022] Among them, the base station adjusting the communication power or increasing the communication power can be to adjust or increase the communication power of the electromagnetic wave signal transmitted by the base station to the second antenna 3.

[0023] Among them, in this application, the base station can adjust the communication power to a more appropriate power according to the interference intensity value in the interference information, which can include increasing the communication power, decreasing the communication power, or it can also be to keep the communication power unchanged. For example, when the base station receives an electromagnetic wave signal carrying interference information, if it determines that the interference intensity value in the currently received interference information is greater than the interference intensity value in the electromagnetic wave signal received last time, it can correspondingly increase the communication power. If it determines that the interference intensity value in the previously received interference information is less than the interference intensity value in the electromagnetic wave signal received last time, it can correspondingly decrease the communication power. If it determines that the interference intensity value in the previously received interference information is approximately the same as the interference intensity value in the electromagnetic wave signal received last time, it can correspondingly keep the communication power unchanged.

[0024] Among them, in some embodiments of the present application, the interference signal of the first antenna 2 coupled to the second antenna 3 includes the interference signal of the antenna body of the first antenna 2 coupled to the antenna body of the second antenna 3. In some embodiments, when there is also an interference signal in the transmitting channel of the first antenna 2 that can be coupled to the receiving channel of the second antenna 3, the interference signal of the first antenna 2 coupled to the second antenna 3 may also include the interference signal of the transmitting channel of the first antenna 2 coupled to the receiving channel of the second antenna 3 when the first antenna 2 transmits an electromagnetic wave signal.

[0025] Furthermore, in the present application, the interference signal of the first antenna 2 coupled to the second antenna 3 may refer to all possible interference signals from the transmitting channel / path of the first antenna 2, including the first antenna 2 and the radio frequency transceiver 11 on the side of the first antenna 2, coupled to the receiving channel / path of the second antenna 3, including the second antenna 3 and the second antenna 3 to the radio frequency transceiver 11 on the side of the second antenna 3 when the first antenna 2 transmits an electromagnetic wave signal, rather than necessarily being limited to the interference signal of the antenna body of the first antenna 2 coupled to the antenna body of the second antenna 3.

[0026] Correspondingly, in the present application, the detection and calculation unit 12 detects the interference signal of the first antenna 2 coupled to the second antenna 3, and also detects all possible interference signals from the transmitting channel / path of the first antenna 2, including the first antenna 2 and the radio frequency transceiver 11 on the side of the first antenna 2, coupled to the receiving channel / path of the second antenna 3, including the second antenna 3 and the second antenna 3 to the radio frequency transceiver 11 on the side of the second antenna 3.

[0027] Among them, in some embodiments, the first antenna 2 supports the transceiver of electromagnetic wave signals in the first frequency band, the second antenna 3 supports the transceiver of electromagnetic wave signals in the second frequency band, and the detection and calculation unit 12 is used to detect the electromagnetic wave signals in the first frequency band of the first antenna 2 coupled to the second antenna 3 when the first antenna 2 transmits an electromagnetic wave signal to obtain the interference signal. Among them, the first frequency band and the second frequency band are different.

[0028] That is, in some embodiments, the first antenna 2 supports the transceiver of electromagnetic wave signals in the first frequency band, and the interference signal of the first antenna 2 coupled to the second antenna 3 can be the electromagnetic wave signals in the first frequency band coupled from the first antenna 2 to the second antenna 3 when the first antenna 2 transmits the electromagnetic wave signals in the first frequency band.

[0029] Among them, in the present application, the first antenna 2 and the second antenna 3 are not specifically two antennas. The first antenna 2 is mainly used as an interfering antenna, and the second antenna 3 is mainly used as an interfered antenna.

[0030] Among them, Figure 1 the shown scenario takes the number of the first antenna 2 and the second antenna 3 both being one as an example, that is, the two antennas of the first antenna 2 and the second antenna 3 are used for illustration. In Figure 1 the shown scenario, only the interference situation between the two antennas is considered, and since the frequency bands supported by the two antennas are different, therefore, the electromagnetic wave signal of the first frequency band coupled by the first antenna 2 to the second antenna 3 is actually the electromagnetic wave signal of other frequency bands except the electromagnetic wave signal of the second frequency band. That is, in some embodiments, the detection and calculation unit 12 detects the electromagnetic wave signal of the first frequency band coupled by the first antenna 2 to the second antenna 3 to obtain the interference signal, which may also refer to the electromagnetic wave signal of other frequency bands except the electromagnetic wave signal of the second frequency band detected by the detection and calculation unit 12 from the second antenna 3 to obtain the interference signal.

[0031] Furthermore, in the present application, the case where any interfering source antenna, that is, the first antenna 2, causes interference to the interfered party, that is, the second antenna 3, is mainly described. Obviously, when there are other interfering source antennas besides the first antenna 2, the detection and calculation unit 12 can detect the electromagnetic wave signal of the corresponding frequency band coupled by each interfering source antenna such as the first antenna 2 to the second antenna 3 when each interfering source antenna such as the first antenna 2 emits an electromagnetic wave signal to obtain the interference signal. The detection and calculation unit 12 can calculate the corresponding interference intensity value according to the interference signals of all detected interfering source antennas, and send the interference intensity value to the radio frequency transceiver 11. For example, the detection and calculation unit 12 can calculate the corresponding interference intensity value according to the interference signal of each detected interfering source antenna, and sum all the interference intensity values to obtain the final interference intensity value.

[0032] Among them, in the present application, the first frequency band and the second frequency band are different, which may mean that the frequency range corresponding to the first frequency band does not overlap with the frequency range corresponding to the second frequency band.

[0033] In some embodiments, the second antenna 3 receives and sends electromagnetic wave signals of the second frequency band in a time-division manner, and the detection and calculation unit 12 detects the electromagnetic wave signal of the first frequency band coupled by the first antenna 2 to the second antenna 3 in a specific time window when the first antenna 2 emits an electromagnetic wave signal to obtain the interference signal, where the specific time window is the time period when the second antenna 3 does not receive the electromagnetic wave signal of the second frequency band.

[0034] That is, in some embodiments, the second antenna 3 receives and transmits electromagnetic wave signals of a second frequency band in a time-division manner. When the first antenna 2 transmits electromagnetic wave signals, the detection and calculation unit 12 detects the electromagnetic wave signals of a first frequency band coupled from the first antenna 2 to the second antenna 3 in a specific time window, which is the time period when the second antenna 3 does not receive the electromagnetic wave signals of the second frequency band, to obtain the interference signal.

[0035] Among them, in the specific time window, which is the time period when the second antenna 3 does not receive the electromagnetic wave signals of the second frequency band, there is no reception of the electromagnetic wave signals of the second frequency band at this time. Therefore, within the specific time window, the electromagnetic wave signals detected by the detection and calculation unit 12 are the interference signals. Therefore, in some embodiments, the electromagnetic wave signals on one side of the second antenna 3 can be detected in the specific time window, which is the time period when the second antenna 3 does not receive the electromagnetic wave signals of the second frequency band, to obtain the interference signal.

[0036] In some embodiments, the second antenna 3 can also receive and transmit electromagnetic wave signals of the second frequency band in any manner. For example, it can also receive and transmit electromagnetic wave signals of the second frequency band in a frequency-division manner. In some embodiments, the detection and calculation unit 12 can also detect the electromagnetic wave signals of other frequency bands except the electromagnetic wave signals of the second frequency band at any moment during the time period when the first antenna 2 transmits electromagnetic wave signals to obtain the interference signal. For example, during any moment within the time period when the first antenna 2 transmits electromagnetic wave signals, the electromagnetic wave signals of the first frequency band coupled from the first antenna 2 to the second antenna 3 are detected to obtain the interference signal.

[0037] That is, in some embodiments, since the second antenna 3 supports the reception and transmission of electromagnetic wave signals of the second frequency band, when there are electromagnetic wave signals of other frequency bands on one side of the second antenna 3, they are generally interference signals. Therefore, the detection and calculation unit 12 can also detect the electromagnetic wave signals of other frequency bands except the electromagnetic wave signals of the second frequency band to obtain the interference signal.

[0038] Among them, in some embodiments, when the detection and calculation unit 12 can also detect electromagnetic wave signals in other frequency bands other than the electromagnetic wave signals in the second frequency band at any time during the period when the first antenna 2 emits electromagnetic wave signals to obtain the interference signal, a filter can be provided on the detection path between the detection and calculation unit 12 and the second antenna 3. For example, a band-stop filter can be provided to filter out the electromagnetic wave signals in the second frequency band and only allow electromagnetic wave signals in other frequency bands other than the electromagnetic wave signals in the second frequency band to pass through. Therefore, when there are electromagnetic wave signals in other frequency bands on one side of the second antenna 3, the electromagnetic wave signals in other frequency bands can pass through the band-stop filter and be detected by the detection and calculation unit 12.

[0039] In some embodiments, the detection and calculation unit 12 is configured to detect the interference signal coupled from the first antenna 2 to the second antenna 3 when the signal state of the first antenna 2 changes and when the first antenna emits electromagnetic wave signals.

[0040] That is, in some embodiments, the detection and calculation unit 12 can detect the interference signal coupled from the first antenna 2 to the second antenna 3 when the signal state of the first antenna 2 changes and when the first antenna 2 emits electromagnetic wave signals. Thus, since the interference degree of the first antenna 2 on the second antenna 3 generally remains unchanged when the signal state of the first antenna 2 remains unchanged, the detection and calculation unit 12 can, when the signal state of the first antenna 2 changes, perform the steps of detecting the interference signal coupled from the first antenna 2 to the second antenna 3 when the first antenna 2 emits electromagnetic wave signals and subsequent steps, that is, after detecting the interference signal coupled from the first antenna 2 to the second antenna 3, calculating the current corresponding interference intensity value according to the detected interference signal and sending the interference intensity value to the radio frequency transceiver 11. Subsequently, the radio frequency transceiver 11 carries the current corresponding interference information in the electromagnetic wave signals transmitted by the second antenna 3. Thus, it can not only ensure the timeliness of detection and the timeliness of the interference information carried in the electromagnetic wave signals transmitted by the second antenna 3, but also avoid frequent detection and save power consumption.

[0041] Among them, the signal state of the first antenna 2 may refer to the signal state of the electromagnetic wave signal in the corresponding frequency band transmitted by the first antenna 2. For example, the signal state of the electromagnetic wave signal in the first frequency band transmitted by the first antenna 2. That is, in the present application, since when the first antenna 2 transmits the electromagnetic wave signal in the corresponding frequency band, it will cause interference to the second antenna 3. For example, it will cause interference to the reception of the second antenna 3. Therefore, in the present application, the detection and calculation unit 12 can detect the interference signal coupled from the first antenna 2 to the second antenna 3 when the signal state of the first antenna 2 changes, that is, when the signal state of the electromagnetic wave signal in the corresponding frequency band transmitted by the first antenna 2 changes.

[0042] In some embodiments, the signal state includes at least one of signal power and bandwidth.

[0043] That is, in some embodiments, the signal state of the first antenna 2 includes the signal power or bandwidth of the electromagnetic wave signal in the corresponding frequency band transmitted by the first antenna 2.

[0044] Among them, when the signal power or bandwidth of the electromagnetic wave signal in the corresponding frequency band transmitted by the first antenna 2 changes, it will cause the interference degree of the first antenna 2 to the second antenna 3 to change. Therefore, the detection and calculation unit 12 can detect the interference signal coupled from the first antenna 2 to the second antenna 3 when the signal state of the first antenna 2 changes, that is, when at least one of the signal power and bandwidth of the first antenna 2 changes. When the first antenna 2 transmits the electromagnetic wave signal, the detection and calculation unit 12 can calculate the current corresponding interference intensity value based on the detected interference signal, and obtain the interference intensity value after the signal power or bandwidth of the first antenna 2 changes. Thus, the radio frequency transceiver 11 can carry the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna according to the currently obtained interference intensity value, so that the base station can adjust the communication power with the second antenna 3 to match the interference intensity value according to the interference intensity value in the current interference information. For example, according to the current interference intensity value, the corresponding communication power is adjusted so that the current communication power can satisfy the cancellation of the interference.

[0045] Please refer to Figure 2 , which is a schematic structural diagram showing a further structure of the radio frequency module 1 in some embodiments of the present application.

[0046] Such as Figure 2As shown, the radio frequency module 1 further includes a first signal transceiver processing circuit 13 and a second signal transceiver processing circuit 14. The first signal transceiver processing circuit 13 is connected between the radio frequency transceiver 11 and the first antenna 2 and is used to implement the receiving and transmitting functions of the first antenna 2. The second signal transceiver processing circuit 14 is connected between the radio frequency transceiver 11 and the second antenna 3 and is used to implement the receiving and transmitting functions of the second antenna 3. The detection and calculation unit 12 is at least coupled between the radio frequency transceiver 11 and the first signal transceiver processing circuit 13 and is at least used to receive the control instruction output by the radio frequency transceiver 11 for the first signal transceiver processing circuit 13, and after converting the control instruction, output it to the first signal transceiver processing circuit 13 to implement the control of the first signal transceiver processing circuit 13. Among them, the detection and calculation unit 12 is used to determine that the signal state of the first antenna 2 has changed when the control instruction is to control and adjust the signal state of the first antenna 2.

[0047] That is, in some embodiments, the radio frequency module 1 further includes a first signal transceiver processing circuit 13 located between the radio frequency transceiver 11 and the first antenna 2, and a second signal transceiver processing circuit 14 located between the radio frequency transceiver 11 and the second antenna 3. Among them, the first signal transceiver processing circuit 13 can be used to amplify the radio frequency signal / electromagnetic wave signal output by the radio frequency transceiver 11 and then output it through the first antenna 2, and amplify the electromagnetic wave signal received by the first antenna 2 and then input it to the radio frequency transceiver 11. Moreover, the first signal transceiver processing circuit 13 can also be used to alternately establish a transmission channel or a reception channel in a time-division manner, or simultaneously establish a transmission channel and a reception channel in a frequency-division manner to implement the receiving and transmitting functions of the first antenna 2. Similarly, the second signal transceiver processing circuit 14 can be used to amplify the radio frequency signal / electromagnetic wave signal output by the radio frequency transceiver 11 and then output it through the second antenna 3, and amplify the electromagnetic wave signal received by the second antenna 3 and then input it to the radio frequency transceiver 11. Moreover, the second signal transceiver processing circuit 14 can also be used to alternately establish a transmission channel or a reception channel in a time-division manner, or simultaneously establish a transmission channel and a reception channel in a frequency-division manner to implement the receiving and transmitting functions of the second antenna 3.

[0048] Among them, the sending path of the control instruction can be seen in Figure 2 as shown by the dotted arrow in. In some embodiments, such as Figure 2As shown, the control instruction output by the radio frequency transceiver 11 for the first signal transceiver processing circuit 13 is first sent to the detection and calculation unit 12. After the detection and calculation unit 12 converts the control instruction, it is then output to the first signal transceiver processing circuit 13 to achieve the control of the first signal transceiver processing circuit 13. Therefore, in some embodiments, when the control instruction output by the radio frequency transceiver 11 is to control and adjust the signal state of the first antenna 2, the detection and calculation unit 12 can determine that the signal state of the first antenna 2 has changed, and can perform the foregoing steps of detecting the interference signal coupled from the first antenna to the second antenna and subsequent steps.

[0049] In some embodiments, the control instruction output by the radio frequency transceiver 11 for the first signal transceiver processing circuit 13 can also be directly sent to the first signal transceiver processing circuit 13 to achieve the control of the first signal transceiver processing circuit 13. Moreover, the control instruction of the radio frequency transceiver 11 for the first signal transceiver processing circuit 13 can also be simultaneously output to the detection and calculation unit 12. When the detection and calculation unit 12 receives the control instruction for controlling and adjusting the signal state of the first antenna 2, it determines that the signal state of the first antenna 2 has changed.

[0050] Among them, Figure 2 the shown radio frequency module 1 and Figure 1 the shown radio frequency module 1 mainly further shows the first signal transceiver processing circuit 13 and the second signal transceiver processing circuit 14. For other structures, reference can be made to Figure 1 the relevant content.

[0051] Please refer to Figure 3 , which is another schematic diagram showing the further structure of the radio frequency module 1 in some embodiments of the present application.

[0052] Among them, as Figure 3 shown, the detection and calculation unit 12 includes a detection module 121 and a calculation module 122. The detection module 121 is used to detect the interference signal coupled from the first antenna 2 to the second antenna 3, and the calculation module 122 is used to calculate the corresponding interference intensity value according to the interference signal detected by the detection module 121 and send the interference intensity value to the radio frequency transceiver 11.

[0053] That is, in some embodiments, the detection and calculation unit 12 includes a detection module 121 and a calculation module 122. The detection module 121 is configured to detect the interference signal coupled from the first antenna 2 to the second antenna 3, and the calculation module 122 is configured to calculate a corresponding interference intensity value based on the interference signal detected by the detection module 121 and send the interference intensity value to the radio frequency transceiver 11.

[0054] In some embodiments, as described above, the radio frequency module 1 further includes a first signal transceiver processing circuit 13 and a second signal transceiver processing circuit 14. The first signal transceiver processing circuit 13 is connected between the radio frequency transceiver 11 and the first antenna 2 and is configured to implement the receiving and transmitting functions of the first antenna 2. The second signal transceiver processing circuit 14 is connected between the radio frequency transceiver 11 and the second antenna 3 and is configured to implement the receiving and transmitting functions of the second antenna 3. Among them, as Figure 3 shown, the detection and calculation unit 12 further includes an instruction conversion module 123. The instruction conversion module 123 is at least connected between the radio frequency transceiver 11 and the first signal transceiver processing circuit 13 and is at least configured to receive a control instruction output by the radio frequency transceiver 11 for the first signal transceiver processing circuit, convert the control instruction, and then output it to the first signal transceiver processing circuit 13 to implement the control of the first signal transceiver processing circuit 13.

[0055] That is, in some embodiments, as Figure 3 shown, the detection and calculation unit 12 further includes an instruction conversion module 123. The instruction conversion module 123 is at least connected between the radio frequency transceiver 11 and the first signal transceiver processing circuit 13. The instruction conversion module 123 is configured to receive a control instruction output by the radio frequency transceiver 11 for the first signal transceiver processing circuit, convert the control instruction, and then output it to the first signal transceiver processing circuit 13.

[0056] In some embodiments, the instruction conversion module 123 is connected to the computing module 122. After receiving the control instruction for the first signal transceiver processing circuit output by the radio frequency transceiver 11, the instruction conversion module 123 further forwards it to the computing module 122. When the control instruction output by the radio frequency transceiver 11 is to control and adjust the signal state of the first antenna 2, the computing module 122 can determine that the signal state of the first antenna 2 has changed, and can control the detection module 121 to perform the foregoing detection of the interference signal coupled from the first antenna to the second antenna, and after receiving the interference signal detected by the detection module 121, calculate the corresponding interference intensity value according to the interference signal, and send the interference intensity value to the radio frequency transceiver 11. Among them, the computing module 122 can be regarded as the processing module of the detection and calculation unit 12, and realizes the corresponding processing and control functions.

[0057] Among them, as Figure 3 shown, in some embodiments, the detection module 121 further includes a detector 121a and a low noise amplifier (LNA, Low Noise Amplifier) 121b. The low noise amplifier 121b is connected between the detector 121a and the computing module 122. The detector 121a is used to acquire the interference signal coupled from the first antenna 2 to the second antenna 3, and the low noise amplifier 121b is used to amplify the interference signal and input it to the computing module 122. The computing module 122 calculates the corresponding interference intensity value according to the amplified interference signal.

[0058] That is, in some embodiments, the detection module 121 may specifically include a detector 121a and a low noise amplifier 121b, and the detector 121a is used to acquire the interference signal coupled from the first antenna 2 to the second antenna 3, and the low noise amplifier 121b is used to amplify the interference signal and input it to the computing module 122, so that the interference signal can be effectively detected.

[0059] Among them, the detector 121a can also be called a phase detector or a demodulator. The detector 121a can specifically extract the original information signal from the modulated signal. Among them, the detector 121a has a wide range of applications in the fields of wireless communication, radar, audio amplifiers, etc. The main function of the detector is to convert the modulated signal (such as AM, FM, PM, etc.) into a low-frequency baseband signal for further processing or direct use.

[0060] Among them, the detection and calculation unit 12 can be a dedicated RF chip, that is, it can be a chip related to RF. Among them, the detection module 121, the calculation module 122, and the instruction conversion module 123 can be circuits or chips integrated in the dedicated RF chip.

[0061] Please refer to Figure 4 , which is a schematic structural diagram showing a further structure of the RF module 1 in some embodiments of the present application.

[0062] As Figure 4 shown, the first signal transceiver processing circuit 13 includes a first power amplifier 131 and a first low-noise amplifier 132. The RF transceiver 11 includes a first signal transmitting end Tx1 and a first signal receiving end Rx1. The first power amplifier 131 is coupled between the first signal transmitting end and the first antenna 2, and is configured to amplify the electromagnetic wave signal of the corresponding frequency band output by the first signal transmitting end Tx1 and transmit it through the first antenna 2. The first low-noise amplifier 132 is coupled between the first signal receiving end Rx1 and the first antenna 2, and is configured to amplify the electromagnetic wave signal of the corresponding frequency band received by the first antenna 2 and then transmit it to the first signal receiving end Rx1. In some embodiments, after the detection and calculation unit 12 converts the control instruction, it outputs to the first power amplifier 131 of the first signal transceiver processing circuit 13 to control the working parameters of the first power amplifier 131, and the working parameters at least include the amplification factor.

[0063] That is, in some embodiments, the first signal transceiver processing circuit 13 includes a first power amplifier 131 and a first low-noise amplifier 132. Among them, the input end of the first power amplifier 131 is connected / coupled to the first signal transmitting end Tx1 of the RF transceiver 11, and the output end of the first power amplifier 131 is coupled to the first antenna 2. After the radio frequency signal / electromagnetic wave signal output by the first signal transmitting end Tx1 of the RF transceiver 11 is amplified by the first power amplifier 131, it is output through the first antenna 2 to realize the transmitting function of the first antenna 2. In addition, the input end of the first low-noise amplifier 132 is coupled to the first antenna 2, and the output end of the first low-noise amplifier 132 is connected to the first signal receiving end Rx1 of the RF transceiver 11. After the electromagnetic wave signal received by the first antenna 2 is amplified by the first low-noise amplifier 132 and input to the first signal receiving end Rx1 of the RF transceiver 11, it is processed by the RF transceiver 11 to realize the receiving function of the first antenna 2.

[0064] Among them, the control instruction output by the radio frequency transceiver 11 can specifically be a control instruction for controlling and adjusting the operating parameters of the first power amplifier 131 of the first signal transceiver processing circuit 13, such as a control instruction for controlling and adjusting the amplification factor. Among them, when the amplification factor of the first power amplifier 131 changes, the signal state such as the signal power of the electromagnetic wave signal transmitted through the first antenna 2 will change. Therefore, in some embodiments, when the detection and calculation unit 12 receives the control instruction output by the radio frequency transceiver 11 for controlling and adjusting the operating parameters of the first power amplifier 131, it can confirm that the signal state of the first antenna 2 has changed, and can perform the foregoing detection of the interference signal coupled from the first antenna 2 to the second antenna 3, and re-obtain the current interference intensity value.

[0065] Among them, the connection path between the first signal transmitting end Tx1 and the first antenna 2 is the transmission channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2, and the first power amplifier 131 is located in the transmission channel. Correspondingly, the connection path between the first signal receiving end Rx1 and the first antenna 2 is the receiving channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2, and the first low-noise amplifier 132 is located in the receiving channel.

[0066] In some embodiments, the first signal transceiver processing circuit 13 further includes a first channel selector 133. The first channel selector 133 is connected between the first power amplifier 131, the first low-noise amplifier 132, and the first antenna 2. The first channel selector 133 is used to cooperate with the first power amplifier 131 to form a transmission channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2, and / or cooperate with the first low-noise amplifier 132 to form a receiving channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2.

[0067] Among them, in some embodiments, when the first antenna 2 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the first frequency band, in a frequency division manner, the first channel selector 133 may include two filters. One filter is connected between the first power amplifier 131 and the first antenna 2, and the other filter is connected between the first low-noise amplifier 132 and the first antenna 2, and cooperate with the first power amplifier 131 to form a transmission channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2, and cooperate with the first low-noise amplifier 132 to form a receiving channel of the electromagnetic wave signal in the corresponding frequency band supported by the first antenna 2.

[0068] Wherein, when the first antenna 2 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the first frequency band, by means of frequency division, the uplink frequency band and the downlink frequency band of the electromagnetic wave signals in the first frequency band are different. Therefore, the two filters can be two band-pass filters corresponding to the uplink frequency band and the downlink frequency band of the electromagnetic wave signals in the first frequency band, that is, only the electromagnetic wave signals in the uplink frequency band and the downlink frequency band are allowed to pass through respectively.

[0069] Wherein, in some embodiments, when the first antenna 2 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the first frequency band, by means of time division, the first channel selector 133 may include a selection switch, and the selection switch is connected between the first power amplifier 131, the first low noise amplifier 132 and the first antenna 2, and is used to select to establish a connection between the first antenna 2 and the first power amplifier 131, or establish a connection between the first antenna 2 and the first low noise amplifier 132. Thus, a transmission channel for electromagnetic wave signals in the corresponding frequency band supported by the first antenna 2 is formed in cooperation with the first power amplifier 131, or a reception channel for electromagnetic wave signals in the corresponding frequency band supported by the first antenna 2 is formed in cooperation with the first low noise amplifier 132.

[0070] Please continue to refer to Figure 4 , the second signal transceiver processing circuit 14 includes a second power amplifier 141 and a second low noise amplifier 142. The radio frequency transceiver 11 further includes a second signal transmitting end Tx2 and a second signal receiving end Rx2. The second power amplifier 141 is coupled between the second signal transmitting end Tx2 and the second antenna 3, and is used to amplify the electromagnetic wave signals in the corresponding frequency band output by the second signal transmitting end Tx2 and transmit them through the second antenna 3. The second low noise amplifier 142 is coupled between the second signal receiving end Rx2 and the second antenna 3, and is used to amplify the electromagnetic wave signals in the corresponding frequency band received by the second antenna 3 and then transmit them to the second signal receiving end Rx2.

[0071] Among them, the input end of the second power amplifier 141 is connected / coupled to the second signal transmitting end Tx2 of the radio frequency transceiver 11, and the output end of the second power amplifier 141 is coupled to the second antenna 3. Thus, the second power amplifier 141 can receive the electromagnetic wave signal of the corresponding frequency band output by the second signal transmitting end Tx2, and after amplifying the electromagnetic wave signal of the corresponding frequency band output by the second signal transmitting end Tx2, transmit it through the second antenna 3. Among them, the input end of the second low-noise amplifier 142 is coupled to the second antenna 3, and the output end of the second low-noise amplifier 142 is coupled to the second signal receiving end Rx2. Thus, the second low-noise amplifier 142 can receive the electromagnetic wave signal of the corresponding frequency band received by the second antenna 3, and after amplifying the electromagnetic wave signal of the corresponding frequency band received by the second antenna 3, transmit it to the second signal receiving end Rx2.

[0072] Among them, similarly, the connection path between the second signal transmitting end Tx2 and the second antenna 3 is the transmission channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3, and the second power amplifier 141 is located in the transmission channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3. Correspondingly, the connection path between the second signal receiving end Rx2 and the second antenna 3 is the receiving channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3, and the second low-noise amplifier 142 is located in the receiving channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3.

[0073] In some embodiments, the second signal transceiver processing circuit 14 further includes a second channel selector 143. The second channel selector 143 is connected between the second power amplifier 141, the second low-noise amplifier 142, and the second antenna 3. The second channel selector 143 is used to cooperate with the second power amplifier 141 to form a transmission channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3, and / or cooperate with the second low-noise amplifier 142 to form a receiving channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3.

[0074] Among them, in some embodiments, correspondingly, when the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through frequency division, the second channel selector 143 may include two filters. One filter is connected between the second power amplifier 141 and the second antenna 3, and the other filter is connected between the second low noise amplifier 142 and the second antenna 3. The second power amplifier 141 is cooperated to form a transmission channel for electromagnetic wave signals in the corresponding frequency band supported by the second antenna 3, and the second low noise amplifier 142 is cooperated to form a reception channel for electromagnetic wave signals in the corresponding frequency band supported by the second antenna 3.

[0075] Among them, when the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through frequency division, the uplink frequency band and the downlink frequency band of the electromagnetic wave signals in the second frequency band are different. Therefore, the two filters may be two band-pass filters corresponding to the uplink frequency band and the downlink frequency band of the electromagnetic wave signals in the second frequency band, that is, only the electromagnetic wave signals in the uplink frequency band and the downlink frequency band of the second frequency band are allowed to pass through respectively.

[0076] Among them, in some embodiments, when the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through time division, the second channel selector 143 may include a selection switch. The selection switch is connected between the second power amplifier 141, the second low noise amplifier 142 and the second antenna 3, and is used to select to establish a connection between the second antenna 3 and the second power amplifier 141, or establish a connection between the second antenna 3 and the second low noise amplifier 142. Thus, the second power amplifier 141 is cooperated to form a transmission channel for electromagnetic wave signals in the corresponding frequency band supported by the second antenna 3, or the second low noise amplifier 142 is cooperated to form a reception channel for electromagnetic wave signals in the corresponding frequency band supported by the second antenna 3.

[0077] Among them, when the first antenna 2 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the first frequency band, through frequency division, the first frequency band may include a corresponding uplink frequency band and a downlink frequency band. When the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through frequency division, the second frequency band may also include a corresponding uplink frequency band and a downlink frequency band. Among them, when the first antenna 2 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the first frequency band, through time division, both the uplink (transmission) and downlink (reception) frequency bands are the first frequency band. When the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through time division, both the uplink (transmission) and downlink (reception) frequency bands are the second frequency band.

[0078] Among them, in some embodiments, the first antenna 2 can support the transceiver of electromagnetic wave signals in the first frequency band through frequency division. The first frequency band includes a corresponding uplink frequency band and a downlink frequency band. When the second antenna 3 supports the transceiver of electromagnetic wave signals in a corresponding frequency band, such as the second frequency band, through time division, the uplink (transmission) and downlink (reception) frequency bands are both the second frequency band. Among them, the first channel selector 133 can be a duplexer including two filters, and the second channel selector 143 can be a selection switch. Figure 4 In the case where the second channel selector 143 is a selection switch, and specifically a single-pole double-throw switch is taken as an example for illustration.

[0079] In some embodiments, the first frequency band supported by the first antenna 2 is the B3 frequency band, and the frequency range is approximately 1710 MHz to 1880 MHz. The uplink frequency band of the first frequency band is 1710 MHz to 1785 MHz, and the downlink frequency band is 1805 MHz to 1880 MHz; the second frequency band supported by the second antenna 3 is the N78 frequency band, and the corresponding frequency range is 3.3 GHz to 3.8 GHz.

[0080] Obviously, in some embodiments, the first frequency band supported by the first antenna 2 can also be other frequency bands supported by frequency division, that is, frequency bands including corresponding uplink frequency bands and downlink frequency bands. For example, it can also be frequency bands such as B2. The second frequency band supported by the second antenna 3 can also be other frequency bands supported by time division, that is, frequency bands with the same uplink and downlink frequency bands. For example, it can also be frequency bands such as B41 and N79. Now, in some embodiments, the first frequency band supported by the first antenna 2 can also be a frequency band supported by time division, and the second frequency band supported by the second antenna 3 can also be a frequency band supported by frequency division.

[0081] Among them, as Figure 4 shown, in some embodiments, the second signal transceiver processing circuit 14 further includes at least one transmit filter 144 and at least one receive filter 145. The at least one transmit filter 144 is located in the transmit channel where the second power amplifier 141 is located for realizing transmit filtering, and the at least one receive filter 145 is located in the receive channel where the second low-noise amplifier 142 is located for realizing receive filtering.

[0082] That is, in some embodiments, the second signal transceiver processing circuit 14 can further include a plurality of filters for filtering out noise during the reception and transmission of electromagnetic wave signals in the second frequency band. Among them, the at least one transmit filter 144 and the at least one receive filter 145 can be band-pass filters, that is, they are only used to allow electromagnetic wave signals corresponding to the second frequency band to pass, so that noise in other frequency bands can be filtered out.

[0083] In some embodiments, the at least one transmit filter 144 and the at least one receive filter 145 may be SAW filters (surface acoustic wave filters) or other types of filters.

[0084] Among them, in Figure 4 In the example shown, the at least one transmit filter 144 is one and is located between the second power amplifier 141 and the second channel selector 143; the at least one receive filter 145 is two, one of the receive filters 145 is located between the second low-noise amplifier 142 and the second channel selector 143, and the other receive filter 145 is located between the second signal receiving end Rx2 of the radio frequency transceiver 11 and the second low-noise amplifier 142. Obviously, in some embodiments, the at least one transmit filter 144 may also be two, respectively located on both sides of the second power amplifier 141, and the receive filter 145 may also be only one, located between the second low-noise amplifier 142 and the second channel selector 143, and so on.

[0085] Among them, as mentioned above, in some embodiments, when there is also an interference signal in the transmit channel of the first antenna 2 that can be coupled to the receive channel of the second antenna 3, the interference signal coupled from the first antenna 2 to the second antenna 3 may also include the interference signal when the first antenna 2 emits an electromagnetic wave signal and the transmit channel of the first antenna 2 is coupled to the receive channel of the second antenna 3. Among them, the interference signal coupled from the transmit channel of the first antenna 2 to the receive channel of the second antenna 3 may be the interference signal of the first channel selector 133 coupled to the second channel selector 143 or the connection path between the second channel selector 143 and the second antenna 3, or may also be the interference signal of the connection path between the first channel selector 133 and the first antenna 2 coupled to the second channel selector 143 or the connection path between the second channel selector 143 and the second antenna 3, and so on.

[0086] Please refer to Figure 5 , which is another schematic diagram showing a further structure of the radio frequency module 1 in some embodiments of the present application.

[0087] In some embodiments, as Figure 5 shown, the radio frequency module 1 further includes a coupler 15, and the coupler 15 is located in the receive channel of the electromagnetic wave signal in the corresponding frequency band supported by the second antenna 3, and is used to couple and obtain the interference signal coupled from the first antenna 2 to the second antenna 3. The detection and calculation unit 12 is connected to the coupler 15 and receives the interference signal coupled by the coupler 15.

[0088] That is, in some embodiments, the detection and calculation unit 12 is coupled to the second antenna 3, and may be coupled to the receiving channel of the electromagnetic wave signal of the corresponding frequency band supported by the second antenna 3 through the coupler 15.

[0089] Among them, as Figure 5 shown, the coupler 15 may be located between the second channel selector 143 and the second antenna 3, and is coupled to the connection path between the second channel selector 143 and the second antenna 3. Thus, the coupler 15 can couple and obtain the interference signal coupled from the first antenna 2 to the second antenna 3.

[0090] Among them, since the interference signal coupled from the first antenna 2 to the second antenna 3 is mainly the interference signal coupled from the antenna body of the first antenna 2 to the antenna body of the second antenna 3, therefore, the coupler 15 can be located between the second channel selector 143 and the second antenna 3 to couple and obtain the interference signal, which is basically most or all of the interference signals coupled from the antenna body of the first antenna 2 to the antenna body of the second antenna 3, and can already accurately reflect the current degree of interference.

[0091] In some embodiments, the coupler 15 may also be located between the second channel selector 143 and the second low-noise amplifier 142, and is coupled to the connection path between the second channel selector 143 and the second low-noise amplifier 142. The coupler 15 also couples and obtains the electromagnetic wave signal of the corresponding frequency band received by the second antenna 3 and conducted through the second channel selector 143.

[0092] Among them, Figure 5 in order to add the coupler 15 on the basis of the structure shown in Figure 4 . Obviously, in any of the foregoing embodiments, the coupler 15 can be added.

[0093] In some embodiments, the interference information further includes the identity information of the second antenna 3. That is, in some embodiments, the interference information not only includes the interference intensity value of the second antenna 3 being interfered by the first antenna 2, but also includes the identity information of the interfered second antenna 3. Among them, the identity information of the second antenna 3 is used to mark / indicate the identity of the second antenna 3. Thus, after the base station receives the interference information carried in the electromagnetic wave signal transmitted by the second antenna 3, it can determine the identity of the second antenna 3 and the interference intensity value it receives. Thus, when communicating with the second antenna 3 subsequently, it can determine the corresponding identity information in the interference information according to the identity of the second antenna 3 in the current communication, and determine the corresponding interference intensity value, and adjust the communication power with the second antenna 3 to the corresponding communication power according to the interference intensity value to cancel the interference.

[0094] Furthermore, the interference information includes the identity information of the second antenna 3 and the interference intensity value, which is equivalent to including the identity information and the interference intensity value that form a corresponding relationship. When the base station communicates with a certain antenna, for example, the second antenna 3 subsequently, when it determines that the identity of the currently communicating antenna is consistent with the identity information of the second antenna 3 in the received interference information, it can further obtain the interference intensity value in the interference information, and adjust the communication power with the second antenna 3 to the corresponding communication power according to the interference intensity value to cancel the interference.

[0095] Of course, in some embodiments, when the communication connection with the second antenna 3 is always maintained after the base station receives the interference information carried in the electromagnetic wave signal transmitted by the second antenna 3, the interference information may not need to include the identity information of the second antenna 3. After the base station receives the interference information carried in the electromagnetic wave signal transmitted by the second antenna 3, it can adjust the communication power between it and the second antenna 3 with which the communication connection has been established currently.

[0096] Among them, in this application, the communication power adjusted by the base station may be the transmission power of the base station sending a signal to the second antenna 3.

[0097] Please refer to Figure 6 , which is a further structural schematic diagram showing a further structure of the radio frequency module 1 in some embodiments of this application.

[0098] In some embodiments, the interference information further includes the identity information of the second antenna 3, such as Figure 6As shown, the number of the second antennas 3 includes at least two. The detection and calculation unit 12 is configured to, when the first antenna 2 transmits an electromagnetic wave signal, successively detect, within the transmission period of the electromagnetic wave signal transmitted by the first antenna 2, the interference signals coupled from the first antenna 2 to each of the second antennas 3, calculate the corresponding interference intensity values according to each detected interference signal, and successively send the calculated interference intensity values to the radio frequency transceiver 11. The radio frequency transceiver 11 determines the identity information of the second antenna 3 corresponding to the interference intensity value according to the reception order of the interference intensity values, generates the interference information corresponding to each second antenna 3 according to each interference intensity value and the corresponding identity information, and the radio frequency transceiver 11 carries the corresponding interference information in the electromagnetic wave signal transmitted by each second antenna 3.

[0099] That is, in some embodiments, the number of the second antennas 3 may include at least two. When the first antenna 2 transmits an electromagnetic wave signal, at least two second antennas 3 may all be interfered by the first antenna 2. The detection and calculation unit 12 may, when the first antenna 2 transmits an electromagnetic wave signal, successively detect, within the transmission period of the electromagnetic wave signal transmitted by the first antenna 2, the interference signals coupled from the first antenna 2 to each of the second antennas 3, calculate the corresponding interference intensity values according to each detected interference signal, and successively send the calculated interference intensity values to the radio frequency transceiver 11.

[0100] Among them, in some embodiments, a corresponding relationship is preset between the transmission order of the interference intensity values of the at least two second antennas 3 and the identity information of the second antennas 3, that is, a corresponding relationship is preset between the reception order of the interference intensity values received by the radio frequency transceiver 11 and the identity information of the second antennas 3. The radio frequency transceiver 11 determines the identity information of the second antenna 3 corresponding to the received interference intensity value according to the preset corresponding relationship between the reception order and the second antennas 3 and the reception order of the currently received interference intensity value. That is, the radio frequency transceiver 11 may determine the identity information according to the reception order of the interference intensity values and the corresponding relationship, that is, determine the identity information of the second antenna 3 corresponding to the currently received interference intensity value, and may generate the interference information corresponding to each second antenna 3 according to each interference intensity value and the corresponding identity information, and the radio frequency transceiver 11 carries the corresponding interference information in the electromagnetic wave signal transmitted by each second antenna 3.

[0101] Thus, when there are multiple second antennas 3, by determining the identity information of the second antenna 3 corresponding to the currently received interference intensity value, and generating corresponding interference information for each interference intensity value and the corresponding identity information, therefore, the interference information of each second antenna 3 includes both the interference intensity value and the identity information of the corresponding second antenna 3. When the radio frequency transceiver 11 transmits an electromagnetic wave signal through any second antenna 3, it can determine the interference information to which the identity information consistent with the identity of the second antenna 3 currently transmitting the electromagnetic wave signal belongs, and carry the interference information in the electromagnetic wave signal transmitted by the second antenna 3.

[0102] Among them, the second antenna 3 may include at least two. When the second antenna 3 supports the transceiver of electromagnetic wave signals in the second frequency band, at least two of the second antennas 3 can at least form a 2×2 MIMO (Multiple Input Multiple Output) antenna system, which is beneficial to improving the communication performance of the second frequency band.

[0103] In some embodiments, as Figure 6 shown, taking four of the at least two second antennas 3 as an example, the four second antennas 3 can form a 4×4 MIMO antenna system, which is beneficial to improving the communication performance of the second frequency band.

[0104] Among them, as Figure 6 shown, in some embodiments, the second channel selector 143 can be a multiplexer, including a plurality of T ports P11 and a plurality of P ports P12. The number of the plurality of P ports P12 can be the same as the number of the second antennas 3. For example, as Figure 6 shown, they are all four. The four P ports P12 are respectively connected to the four second antennas 3.

[0105] Among them, as Figure 6 shown, the second signal transceiver processing circuit 14 of the radio frequency module 1 may include at least two second low-noise amplifiers 142. For example, as Figure 6 shown, there are four second low-noise amplifiers. Among them, at least two receiving channels can be formed between the radio frequency transceiver 11 and the at least two second antennas 3. For example, as Figure 6 shown, there are four receiving channels. Each second low-noise amplifier 142 is arranged in a corresponding receiving channel. As Figure 6 shown, one of the T ports P11 is coupled to the second power amplifier 141, and the remaining T ports P11 are respectively connected to the at least two second low-noise amplifiers 142. For example, as Figure 4As shown, the number of the T ports P11 is five. One of the T ports P11 is coupled to the second power amplifier 141, and the remaining four T ports P11 are respectively connected to four second low-noise amplifiers 142.

[0106] Among them, the second channel selector 143 can selectively establish a connection between the T port P11 coupled to the second power amplifier 141 and any one of the P ports P12, so as to realize the round-robin function of at least two second antennas 3, for example, Figure 6 As shown, the round-robin function of the four second antennas 3. Among them, the second channel selector 143 can also selectively establish a connection between the T port P11 connected to the second low-noise amplifier 142 and one of the corresponding P ports P12, or simultaneously establish connections between the four T ports P11 connected to the second low-noise amplifier 142 and the four P ports P12 respectively, so as to simultaneously form the receiving channels of the four second antennas 3, and realize the simultaneous reception of electromagnetic wave signals in the second frequency band.

[0107] Among them, as Figure 6 shown, the radio frequency module 1 also includes at least two second signal receiving ends Rx2, for example, Figure 6 as shown, the four second signal receiving ends Rx2. Each second low-noise amplifier is also connected to a corresponding second signal receiving end Rx2, and amplifies the electromagnetic wave signal received by the corresponding second antenna 3 and inputs it to the corresponding second signal receiving end Rx2 for processing by the radio frequency transceiver 11.

[0108] At present, the SRS switching antenna round-robin function of mobile phones, that is, the SRS switching 4-antenna transmission function, is a mandatory option in the "Technical White Paper for China Mobile 5G Scale Test_Terminal" of China Mobile Communications Corporation CMCC and is optional in the 3rd Generation Partnership Project 3GPP. Its main purpose is for the base station to measure the uplink signals of the mobile phone's 4 antennas, and then confirm the channel quality and parameters of the 4 channels. According to channel reciprocity, the beamforming of the downlink optimal multi-input multi-output Massive MIMO antenna array is performed on the 4 channels, and finally the best data transmission performance of the downlink 4x4 MIMO is obtained.

[0109] Among them, the SRS switching antenna round-robin function is generally realized by using 4 antennas as the transmitting antennas in turn. In this application, the second channel selector 143 can selectively establish a connection between the T port P11 coupled to the second power amplifier 141 and any one of the P ports P12, so as to realize Figure 6 as shown, the round-robin function of the four second antennas 3.

[0110] In some embodiments, performing SRS4 antenna round-robin or autonomous transmission switching through the radio frequency module 1 may include:

[0111] In the first transmission cycle, the first second antenna 3 connected by the radio frequency module 1 transmits a signal to support the base station in detecting the channel quality of the corresponding antenna;

[0112] In the second transmission cycle, the second second antenna 3 connected by the radio frequency module 1 transmits a signal to support the base station in detecting the channel quality of the corresponding antenna;

[0113] In the third transmission cycle, the third second antenna 3 connected by the radio frequency module 1 transmits a signal to support the base station in detecting the channel quality of the corresponding antenna;

[0114] In the fourth transmission cycle, the fourth second antenna 3 connected by the radio frequency module 1 transmits a signal to support the base station in detecting the channel quality of the corresponding antenna.

[0115] Wherein, when there are multiple second antennas 3, the radio frequency module 1 may also include multiple aforementioned couplers 15 (as Figure 5 shown) for respectively coupling and obtaining the interference signals coupled to the corresponding second antennas 3. Each coupler 15 is located between the corresponding second channel selector 143 and the corresponding second antenna 3 and is coupled to the connection path between the second channel selector 143 and the corresponding second antenna 3. Thus, each coupler 15 can couple and obtain the interference signals that the first antenna 2 couples to the corresponding second antenna 3. For the setting positions, etc. of each coupler 15, reference can be made to the relevant content of the foregoing Figure 5 , which will not be elaborated here.

[0116] Wherein, Figure 6 Compared with the structure of the foregoing embodiment, the main difference in the structure shown is that the number of second antennas 3 is at least two, the second channel selector 143 can be a multiplexer switch, and the receiving channels of the second antennas 3 are also at least two, so as to realize a structure of one transmission channel and multiple receiving channels. For other specific structures, such as the structure of the first signal transceiver processing circuit 13 and the structure in which each second low-noise amplifier 142 is arranged in a corresponding receiving channel, etc., reference can be made to the relevant introduction of the foregoing embodiment.

[0117] Among them, in the present application, when the radio frequency transceiver 11 controls the first antenna 2 to transmit electromagnetic wave signals in the corresponding frequency band, that is, the electromagnetic wave signals in the first frequency band, it can also send corresponding notification information to the detection and calculation unit 12. For example, it is sent to the calculation module 122 of the detection and calculation unit 12. Among them, the notification information may include the start time and duration of the electromagnetic wave signals in the first frequency band transmitted by the first antenna 2. The duration may be the aforementioned transmission period or may include multiple aforementioned transmission periods. Thus, after receiving the notification information, the detection and calculation unit 12 can start detecting the interference signals coupled from the first antenna 2 to the second antenna 3.

[0118] Thus, through the radio frequency module 1 of the present application, the interference signals coupled from the first antenna 2 to the second antenna 3 can be detected, and the corresponding interference intensity values can be calculated based on the detected interference signals. Then, through the radio frequency transceiver 11, corresponding interference information is carried in the electromagnetic wave signals transmitted through the second antenna 3. Among them, the interference information at least includes the interference intensity value, and the interference information corresponding to the current interference degree can be effectively reported. Thus, the base station can adjust the communication power with the second antenna 3 according to the interference information carried in the received electromagnetic wave signals. For example, the communication power with the second antenna 3 is increased to eliminate the interference. Among them, since in the present application, when the first antenna 2 transmits electromagnetic wave signals, the interference signals coupled from the first antenna 2 to the second antenna 3 are detected in real time, and the corresponding interference intensity values are calculated based on the detected interference signals. Therefore, the interference intensity value can accurately reflect the current real interference degree, and the base station can adjust the communication power to a more appropriate power according to the interference intensity value in the interference information.

[0119] Please refer to Figure 7 , which is the structural block diagram of the radio frequency system 100 in some embodiments of the present application.

[0120] As Figure 7 shown, the radio frequency system 100 includes the radio frequency module 1 described in any of the foregoing embodiments, as well as the first antenna 2 and the second antenna 3.

[0121] The radio frequency module 1 is connected to the first antenna 2 and the second antenna 3, and transmits or receives electromagnetic wave signals in the corresponding frequency band through the first antenna 2 and the second antenna 3.

[0122] Please refer to Figure 8 , which is the structural block diagram of the electronic device 200 in some embodiments of the present application.

[0123] As Figure 8As shown, the electronic device 200 includes the radio frequency system 100, that is, it includes the radio frequency module 1 described in any of the foregoing embodiments, the first antenna 2, and the second antenna 3.

[0124] Thus, in the electronic device 200 of the present application, the detection and calculation unit 12 of the radio frequency module 1 can detect the interference signal coupled from the first antenna 2 to the second antenna 3, and calculate the corresponding interference intensity value according to the detected interference signal. Then, according to the interference intensity value, the radio frequency transceiver 11 carries the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna 3. The interference information at least includes the interference intensity value, so that the interference information corresponding to the current interference degree can be effectively reported. Therefore, the base station can adjust the communication power with the second antenna 3 according to the interference information carried in the received electromagnetic wave signal. For example, increasing the communication power with the second antenna 3 can eliminate the interference. Since in the present application, when the first antenna 2 transmits an electromagnetic wave signal, the interference signal coupled from the first antenna 2 to the second antenna 3 is detected in real time, and the corresponding interference intensity value is calculated according to the detected interference signal, the interference intensity value can accurately reflect the current actual interference degree, and the base station can adjust the communication power to a more appropriate power according to the interference intensity value in the interference information.

[0125] Please refer to Figure 9 , which is a flowchart of the interference information reporting method in some embodiments of the present application. In some embodiments, the interference information reporting method is used to report the interference information of the second antenna affected by the first antenna. As Figure 9 shown, the interference information reporting method includes:

[0126] 901: When the first antenna transmits an electromagnetic wave signal, detect the interference signal coupled from the first antenna to the second antenna, and calculate the corresponding interference intensity value according to the detected interference signal; and

[0127] 902: According to the interference intensity value, carry the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna, where the interference information at least includes the interference intensity value.

[0128] Thus, in the present application, an interference intensity value corresponding to the detected interference signal is calculated, and the corresponding interference information is carried in the electromagnetic wave signal transmitted by the second antenna, where the interference information at least includes the interference intensity value. Thus, the base station can adjust the power of communicating with the second antenna according to the interference information carried in the received electromagnetic wave signal. For example, by increasing the power of communicating with the second antenna, the interference can be eliminated. The interference signal coupled from the first antenna to the second antenna can be detected in real time when the first antenna transmits the electromagnetic wave signal, and the corresponding interference intensity value can be calculated according to the detected interference signal. Therefore, the interference intensity value can accurately reflect the current true interference degree, and the base station can adjust the communication power to a more appropriate power according to the interference intensity value in the interference information.

[0129] Among them, the interference information reporting method can be applied to the foregoing radio frequency module 1, or radio frequency system 100, or electronic device 200. Among them, step 901 can be executed by the detection and calculation unit 12 in the foregoing radio frequency module 1, and step 902 can be executed by the radio frequency transceiver 11 in the foregoing radio frequency module 1.

[0130] In some embodiments, the first antenna supports the transceiver of electromagnetic wave signals in the first frequency band, and the second antenna supports the transceiver of electromagnetic wave signals in the second frequency band. Detecting the interference signal coupled from the first antenna to the second antenna when the first antenna transmits the electromagnetic wave signal may include: detecting the electromagnetic wave signal in the first frequency band coupled from the first antenna to the second antenna when the first antenna transmits the electromagnetic wave signal to obtain the interference signal.

[0131] In some embodiments, the second antenna receives and transmits electromagnetic wave signals in the second frequency band in a time-division manner. Detecting the interference signal coupled from the first antenna to the second antenna when the first antenna transmits the electromagnetic wave signal may include: detecting the electromagnetic wave signal in the first frequency band coupled from the first antenna to the second antenna within a specific time window when the first antenna transmits the electromagnetic wave signal to obtain the interference signal, where the specific time window is the time period when the second antenna does not receive the electromagnetic wave signal in the second frequency band.

[0132] In some embodiments, detecting the interference signal coupled from the first antenna to the second antenna when the first antenna transmits the electromagnetic wave signal may further include: detecting the interference signal coupled from the first antenna to the second antenna when the signal state of the first antenna changes and the first antenna transmits the electromagnetic wave signal.

[0133] Therefore, when the signal state of the first antenna changes, the interference signal coupled from the first antenna to the second antenna is detected only when the first antenna emits an electromagnetic wave signal. This can not only ensure the timeliness of detection and the timeliness of the interference information carried in the electromagnetic wave signal transmitted by the second antenna 3, but also avoid frequent detection and save power consumption.

[0134] In some embodiments, the signal state includes at least one of signal power and bandwidth.

[0135] In some embodiments, the number of the second antennas includes at least two. When detecting the interference signal coupled from the first antenna to the second antenna when the first antenna emits an electromagnetic wave signal, it may further include: when the first antenna emits an electromagnetic wave signal, within the transmission period of the electromagnetic wave signal emitted by the first antenna, sequentially detect the interference signal coupled from the first antenna to each second antenna, and calculate the corresponding interference intensity value according to each detected interference signal.

[0136] In some embodiments, carrying the corresponding interference information in the electromagnetic wave signal transmitted through the second antenna according to the interference intensity value may include: determining the identity information of the second antenna corresponding to the interference intensity value according to the reception order of the interference intensity value, generating the interference information of the corresponding second antenna according to each interference intensity value and the corresponding identity information, and carrying the corresponding interference information in the electromagnetic wave signal transmitted by each second antenna.

[0137] In some embodiments, determining the identity information of the second antenna corresponding to the interference intensity value according to the reception order of the interference intensity value may include: determining the identity information of the second antenna corresponding to the received interference intensity value according to the pre-set correspondence between the reception order and the second antenna and the current reception order of the received interference intensity value.

[0138] As described above, the interference information reporting method can be applied to the foregoing radio frequency module 1, or radio frequency system 100, or electronic device 200. The steps in the interference information reporting method correspond to the functional operations performed by the foregoing radio frequency module 1. For more specific steps, reference can be made to the functional operations performed by the foregoing radio frequency module 1, which will not be elaborated here.

[0139] The radio frequency module 1, radio frequency system 100, electronic device 200, and interference information reporting method of the present application can calculate the corresponding interference intensity value according to the detected interference signal, and carry the corresponding interference information in the electromagnetic wave signal transmitted by the second antenna, where the interference information at least includes the interference intensity value, so as to effectively report the interference information corresponding to the current interference degree. Thus, the base station can adjust the power of communicating with the second antenna according to the interference information carried in the received electromagnetic wave signal. For example, by increasing the power of communicating with the second antenna, the interference can be eliminated. By detecting the interference signal coupled from the first antenna to the second antenna in real time when the first antenna transmits the electromagnetic wave signal, and calculating the corresponding interference intensity value according to the detected interference signal, the interference intensity value can accurately reflect the current actual interference degree, and the base station can adjust the communication power to a more appropriate power according to the interference intensity value in the interference information.
