[0002] Currently, communication equipment operates with the same radio frequency (RF) transceiver performance regardless of the scenario, which can easily lead to the RF transceiver performance failing to meet the requirements of the scenario in which the communication equipment is located. Summary of the Invention

[0003] The main technical problem solved by the radio frequency compensation control method, communication device and storage medium provided in the embodiments of the present invention is that the communication device operates with the same radio frequency transceiver performance in various scenarios, which makes it difficult for the radio frequency transceiver performance to meet the requirements of the scenario in which the communication device is located.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the embodiments of this invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0029] Example 1:

[0030] Currently, the radio frequency (RF) circuits of communication equipment are typically divided into two parts: the main RF circuit and the antenna matching circuit. During normal operation or OTA (Over-The-Air) testing, the main RF circuit and the antenna matching circuit are connected via an RF cable. However, during cable connection testing, this connection is broken, the input of the main RF circuit is connected to its output, and the output is connected to an external instrument. However, in these technologies, the communication equipment operates with the same RF transceiver performance in both scenarios, making it difficult to meet the specific requirements of the communication equipment's operating environment.

[0031] To address the problem in related technologies where communication devices consistently operate with the same RF transceiver performance across different working scenarios, resulting in performance that fails to meet the requirements of those scenarios, this embodiment provides an RF compensation control method. Please refer to [link to relevant documentation]. Figure 1 The following is a flowchart of the radio frequency compensation control method:

[0032] S102: Determine the current connection status of the radio frequency circuit of the communication device.

[0033] The radio frequency (RF) circuit includes a main RF circuit and an antenna matching circuit. The main RF circuit is typically located on one side of the communication equipment's motherboard, while the antenna matching circuit is located on one side of the communication equipment's daughterboard. Normally, the motherboard and daughterboard are two independent boards. The motherboard refers to the board containing the main components of the communication equipment, such as the board containing the processor. The daughterboard is the board used to deploy components that implement a specific function. In this embodiment, the connection state of the RF circuit refers to the connection state between the main RF circuit and the antenna matching circuit, including both connected and disconnected states.

[0034] Please see Figure 2 In the connected state, the main RF circuit 21 is connected to the antenna matching circuit 22. Figure 2 In this circuit, the first terminal C of the main RF circuit 21 is connected to the second terminal B of the antenna matching circuit 22, and the ground terminal G of the main RF circuit 21 is connected to the ground terminal G of the antenna matching circuit 22. It is worth noting that... Figure 2 The diagram shown is not a detailed representation of the main RF circuit and the antenna matching circuit, but merely a general connection diagram of the terminals of the main RF circuit and the antenna matching circuit. Therefore, the connection between the first terminal C of the main RF circuit 21 and the second terminal B of the antenna matching circuit 22 is not actually direct; other components are involved between them.

[0035] Figure 3 The diagram shows a general connection diagram of the main RF circuit 21 and the antenna matching circuit 22 when the RF circuit is in the off state. Figure 3 As can be seen, in the disconnected state, the first terminal C of the main RF circuit 21 is disconnected from the second terminal A of the antenna matching circuit 22. At the same time, the first terminal C of the main RF circuit 21 is connected to the third terminal A. Normally, the third terminal A is also connected to an external test instrument.

[0036] In some examples of this embodiment, the connection state of the communication device's radio frequency (RF) circuit can be determined based on input from a user or tester. For instance, when a tester controls the RF circuit of the communication device to the disconnected state, they can inform the communication device that its RF circuit is currently disconnected by inputting information. Alternatively, when a user controls the RF circuit of the communication device to the connected state, they can inform the communication device that its RF circuit is currently connected by inputting information. In this case, the communication device can determine the current connection state of the RF circuit based on the input information.

[0037] In other examples of this embodiment, the communication device can determine the current connection status of the radio frequency circuit through a detection circuit. See also... Figure 4The diagram shows a detection circuit for detecting the connection status of an RF circuit: the detection circuit includes a detection point T, a pull-up resistor R, a DC blocking device, and a DC passing device.

[0038] The DC blocking device is used to block DC current from passing through, preventing the DC current in the RF detection circuit from affecting the external adjacent devices of the RF circuit 40. "External adjacent devices" refers to devices in the communication equipment that are connected to the RF circuit 40 and work together with it to achieve RF transceiver functions. Typically, one end of the RF circuit 40 is connected to the RF transceiver of the communication equipment, and the other end is connected to the antenna. All three work together to achieve the RF transceiver function of the communication equipment. Therefore, in this case, the antenna and the RF transceiver can be considered two external adjacent devices of the RF circuit 40.

[0039] A DC-passing device allows DC to pass through without affecting radio frequency signals.

[0040] In some examples of this embodiment, the DC blocking device includes a first DC blocking device 411 and a second DC blocking device 412, and the DC passing device includes a first DC passing device 421 and a second DC passing device 422. The following description, in conjunction with... Figure 4 The connection relationship and working principle of the detection circuit and the radio frequency circuit 40 are explained:

[0041] The first end of the pull-up resistor R is connected to the power supply terminal VCC, and the second end is connected to the first terminal a of the RF circuit 40. The second terminal b of the RF circuit 40 is connected to the ground terminal GND through the first straightener device 421. The detection point T is connected to the first terminal of the RF circuit 40 through the second straightener device 422. One end of the first straightener device 411 is connected to the first terminal a of the RF circuit 40, and the other end serves as the first external neighbor device connection terminal L1 for connection with the first external neighbor device. One end of the second straightener device 412 is connected to the second terminal b of the RF circuit 40, and the other end serves as the second external neighbor device connection terminal L2 for connection with the second external neighbor device. In this embodiment, one of the first and second external neighbor devices is an antenna, and the other is an RF transceiver.

[0042] In this embodiment, if detection point T detects a first level, it is determined that the RF circuit is currently in a connected state; if detection point T detects a second level, it is determined that the RF circuit is currently in a disconnected state. The second level is higher than the first level. Therefore, when the RF circuit is currently in a connected state, detection point T will detect a low level, and when the RF circuit is currently in a disconnected state, detection point T will detect a high level.

[0043] Understandably, due to the function of the first DC blocking device 411, the first terminal a of the second DC blocking device 422 is in an "open circuit" state with the connection terminal L1 of the first external adjacent device. Similarly, under the function of the second DC blocking device 412, the second terminal b of the RF circuit 40 is also in an "open circuit" state with the connection terminal L2 of the second external adjacent device. In this case, if the main RF circuit and the antenna matching circuit in the RF circuit 40 are in a connected state, the detection point T can be connected to the power supply terminal VCC through the second DC blocking device 422 and the pull-up resistor R, and can also be connected to the ground terminal GND through the second DC blocking device 422, the RF circuit 40, and the first DC blocking device 421. Since the DC blocking device provides a DC path, the voltage at the detection point T in this case is basically equal to the voltage at the ground terminal, which is a low level. If the main RF circuit and the antenna matching circuit in the RF circuit 40 are disconnected, the detection point T can only be connected to the power supply terminal VCC through the second straightener 422 and the pull-up resistor R. At this time, the electrode of the detection point T is basically equal to the voltage of the power supply terminal VCC, which is a high level.

[0044] Therefore, by determining the voltage level at detection point T, the detection circuit can determine the current connection state between the main RF circuit and the antenna matching circuit in the RF circuit 40, that is, determine the current connection state of the RF circuit. In this embodiment, the output signal of the detection circuit is input to the processor of the communication device, allowing the processor to determine the current connection state of the RF circuit 40 based on the output signal of the detection circuit.

[0045] It is worth noting that, although Figure 4 In the RF circuit 40, terminals a and b are in a connected state, but this does not mean that the RF circuit 40 can only be in a connected state. In some other scenarios, terminals a and b may also be in a disconnected state.

[0046] In some examples of this embodiment, the detection circuit further includes a third DC blocking device; please refer to [link to relevant documentation]. Figure 5 The schematic diagram shown illustrates another detection circuit that detects the connection status of an RF circuit:

[0047] exist Figure 5 In addition to the first DC blocking device 411 and the second DC blocking device 412, the DC blocking device also includes a third DC blocking device 413, which can absorb radio frequency signals from the antenna or from the radio frequency transceiver. One end of the third DC blocking device 413 is connected to the detection point T, and the other end is connected to the ground terminal GND.

[0048] In some examples of this embodiment, the DC blocking device may include a capacitor or a high-resistance device. In some examples, the first DC blocking device 411, the second DC blocking device 412, and the third DC blocking device 413 may all be capacitors or all be high-resistance devices. In other examples of this embodiment, some of the first DC blocking device 411, the second DC blocking device 412, and the third DC blocking device 413 may be capacitors, while others may be high-resistance devices.

[0049] In some examples of this embodiment, the bypass device can be an inductor. For example, in some examples of this embodiment, both the first bypass device 421 and the second bypass device 422 are radio frequency chokes (RFCs). An RF choke is a large inductor. Since the inductive reactance Xl = 2πfL, it can be seen that the RFC is open for DC paths and open for high-frequency AC paths.

[0050] It should be understood that, although Figure 5 In the RF circuit 50, terminals a and b are in an open state, but this does not mean that the RF circuit 50 can only be in an open state. In some other scenarios, terminals a and b may also be in a connected state.

[0051] S104: Perform radio frequency compensation on the communication device based on the connection status.

[0052] After the communication equipment determines the connection status of the RF circuit, RF compensation can be performed according to the RF connection status. Different connection statuses can correspond to different RF compensations. In this embodiment, RF compensation includes at least one of power compensation and matching compensation. In this embodiment, matching compensation refers to setting up a matching circuit for the RF circuit, or connecting the RF circuit to a matching circuit. The so-called matching circuit is an impedance matching circuit.

[0053] For example, in some instances, the state of the radio frequency circuit does not affect the selection of the matching circuit of the communication device. However, when the radio frequency circuit is in the connected state, the communication device can use a first power compensation strategy to compensate the transmit power. When it is determined that the radio frequency circuit is in the disconnected state, the communication device can use a second power compensation strategy to compensate the transmit power. The first power compensation strategy and the second power compensation strategy are different. In some instances of this embodiment, the power compensated under the first power compensation strategy may be higher than the power compensated under the second power compensation strategy. In other instances, the power compensated under the first power compensation strategy may be lower than the power compensated under the second power compensation strategy.

[0054] In other examples, the state of the radio frequency circuit does not affect the selection of the power compensation strategy of the communication device, but the state of the radio frequency circuit will affect the matching compensation strategy of the communication device. In some examples of this embodiment, when the radio frequency circuit is in the connected state, the communication device can connect to the first matching circuit, and when it is determined that the radio frequency circuit is in the disconnected state, the communication device can connect to the second matching circuit, which is different from the first matching circuit.

[0055] In other examples, the state of the radio frequency circuits differs, resulting in different transmit power compensation strategies and matching circuit selections.

[0056] The radio frequency compensation control method provided in this embodiment of the invention can perform different radio frequency compensations based on different radio frequency circuit connection states, thereby enabling the communication device to have different radio frequency transceiver performance in different working scenarios, ensuring that the radio frequency transceiver performance of the communication device meets the requirements of its working scenario.

[0057] Moreover, in the RF compensation control method provided in this embodiment, the communication device can determine the level at the detection point through a simple detection circuit, thereby identifying the current state of the RF connection circuit based on the level at the detection point. This can complete the identification of the RF circuit connection state without significantly increasing the cost of the communication device, the burden on testers or users of the communication device, which is beneficial to improving the user experience of the communication device.

[0058] Example 2:

[0059] This embodiment provides a communication device; please refer to [link / reference]. Figure 6 The diagram shown is a structural schematic of the communication device:

[0060] The communication device 60 includes a status determination unit 602 and a compensation control unit 604. The status determination unit 602 is used to determine the current connection status of the communication device's radio frequency circuit, which includes a main radio frequency circuit and an antenna matching circuit. The connection status is the connection status between the main radio frequency circuit and the antenna matching circuit. The compensation control unit 604 is used to perform radio frequency compensation on the communication device according to the connection status. The radio frequency compensation includes at least one of power compensation and matching compensation.

[0061] In some examples of this embodiment, the state determination unit 602 includes a detection circuit for detecting the current connection state of the radio frequency circuit in the communication device.

[0062] In some examples of this embodiment, the detection circuit includes a detection point T, a pull-up resistor R, a DC blocking device, and a DC passing device. Please continue to refer to... Figure 4DC blocking devices are used to block DC current from passing through, preventing DC current in the RF detection circuit from affecting adjacent devices of the RF circuit 40. "Adjacent devices" refer to devices in the communication equipment that are connected to the RF circuit 40 and work together with it to achieve RF transceiver functions. Typically, one end of the RF circuit 40 is connected to the RF transceiver of the communication equipment, and the other end is connected to the antenna. All three work together to achieve the RF transceiver function of the communication equipment. Therefore, the antenna and the RF transceiver are two adjacent devices of the RF circuit 40.

[0063] A DC-passing device allows DC to pass through without affecting radio frequency signals.

[0064] In some examples of this embodiment, the DC blocking device includes a first DC blocking device 411 and a second DC blocking device 412, and the DC passing device includes a first DC passing device 421 and a second DC passing device 422. The following description, in conjunction with... Figure 4 The connection relationship and working principle of the detection circuit and the radio frequency circuit 40 are explained:

[0065] The first end of the pull-up resistor R is connected to the power supply terminal VCC, and the second end is connected to the first end of the RF circuit 40. The second end of the RF circuit 40 is connected to the ground terminal GND through the first straightener device 421. The detection point T is connected to the first end of the RF circuit 40 through the second straightener device 422. One end of the first DC blocking device 411 is connected to the first end of the RF circuit 40, and the other end serves as the first external neighbor device connection terminal L1 for connection with the first external neighbor device. One end of the second DC blocking device 412 is connected to the second end of the RF circuit 40, and the other end serves as the second external neighbor device connection terminal L2 for connection with the second external neighbor device. In this embodiment, one of the first and second external neighbor devices is an antenna, and the other is an RF transceiver.

[0066] Understandably, due to the function of the first DC blocking device 411, the first terminal of the second DC blocking device 422 is in an "open circuit" state with the connection terminal L1 of the first external adjacent device. Similarly, under the function of the second DC blocking device 412, the second terminal of the RF circuit 40 is also in an "open circuit" state with the connection terminal L2 of the second external adjacent device. In this case, if the main RF circuit and the antenna matching circuit in the RF circuit 40 are in a connected state, the detection point T can be connected to the power supply terminal VCC through the second DC blocking device 422 and the pull-up resistor R, and can also be connected to the ground terminal through the second DC blocking device 422, the RF circuit 40, and the first DC blocking device 421. Since the DC blocking device provides a DC path, the voltage of the detection point T in this case is basically equal to the voltage of the ground terminal, which is a low level. If the main RF circuit and the antenna matching circuit in the RF circuit 40 are in a disconnected state, the detection point T can only be connected to the power supply terminal VCC through the second DC blocking device 422 and the pull-up resistor R. At this time, the voltage of the electrode of the detection point T is basically equal to the voltage of the power supply terminal VCC, which is a high level.

[0067] Therefore, by determining the voltage level at detection point T, the detection circuit can determine the current connection state between the main RF circuit and the antenna matching circuit in the RF circuit 40, that is, determine the current connection state of the RF circuit. In this embodiment, the output signal of the detection circuit is input to the processor of the communication device, allowing the processor to determine the current connection state of the RF circuit 40 based on the output signal of the detection circuit.

[0068] In some examples of this embodiment, the detection circuit also includes a third DC blocking device. Please continue to refer to... Figure 5 In addition to the first DC blocking device 411 and the second DC blocking device 412, the DC blocking device also includes a third DC blocking device 413. One end of the third DC blocking device 413 is connected to the detection point T, and the other end is connected to the ground terminal GND.

[0069] In some examples of this embodiment, the DC blocking device may include a capacitor or a high-resistance device. In some examples, the first DC blocking device 411, the second DC blocking device 412, and the third DC blocking device 413 may all be capacitors or all be high-resistance devices. In other examples of this embodiment, some of the first DC blocking device 411, the second DC blocking device 412, and the third DC blocking device 413 may be capacitors, while others may be high-resistance devices.

[0070] In some examples of this embodiment, the straightening device can be an inductor. For example, in some examples of this embodiment, both the first straightening device 421 and the second straightening device 422 are radio frequency chokes.

[0071] Please see Figure 7The diagram shows a schematic of a detection circuit for detecting the connection status of an RF circuit: the detection circuit includes a detection point T, a pull-up resistor R0, DC blocking devices (first DC blocking device C1, second DC blocking device C2 and third DC blocking device C3), and DC passing devices (first RF choke RFC1 and first RF choke RFC2).

[0072] The first end of the pull-up resistor R0 is connected to the power supply terminal VCC, and the second end is connected to the first terminal a of the RF circuit 70. The second terminal b of the RF circuit 70 is connected to the ground terminal GND through the first RF choke RFC1. The detection point T is connected to the first terminal a of the RF circuit 70 through the second RF choke RFC2. One end of the first DC blocking device C1 is connected to the first terminal a of the RF circuit 70, and the other end serves as the antenna connection terminal L1 for connection to the antenna. One end of the second DC blocking device C2 is connected to the second terminal b of the RF circuit 70, and the other end serves as the transceiver connection terminal L2 for connection to the RF transceiver.

[0073] If the main RF circuit and the antenna matching circuit in RF circuit 70 are in a connected state, the detection point T can be connected to the power supply terminal VCC through the second RF choke RFC2 and the pull-up resistor R, and also to the ground terminal through the second RF choke RFC2, RF circuit 70, and the first RF choke RFC1. Since the DC-passing device provides a DC path, the voltage at detection point T in this case is essentially equal to the voltage at the ground terminal, which is a low level. If the main RF circuit and the antenna matching circuit in RF circuit 70 are in a disconnected state, the detection point T can only be connected to the power supply terminal VCC through the second RF choke RFC2 and the pull-up resistor R. In this case, the voltage at detection point T is essentially equal to the voltage at the power supply terminal VCC, which is a high level.

[0074] It is worth noting that, although Figure 7 In the RF circuit 70, terminals a and b are in a connected state, but this does not mean that the RF circuit 70 can only be in a connected state. In some other scenarios, terminals a and b may also be in a disconnected state.

[0075] Please see Figure 8 The diagram shows a schematic of a detection circuit for detecting the connection status of an RF circuit: the detection circuit includes a detection point T, a pull-up resistor R0, DC blocking devices (first DC blocking device C1, second DC blocking device C2 and third DC blocking device C3), and DC passing devices (first RF choke RFC1 and first RF choke RFC2).

[0076] The first end of the pull-up resistor R0 is connected to the power supply terminal VCC, and the second end is connected to the first terminal a of the RF circuit 80. The second terminal b of the RF circuit 80 is connected to the ground terminal GND through the first RF choke RFC1. The detection point T is connected to the first terminal a of the RF circuit 80 through the second RF choke RFC2. One end of the first DC blocking device C1 is connected to the first terminal a of the RF circuit 80, and the other end serves as the transceiver connection terminal L2 for connection to the RF transceiver. One end of the second DC blocking device C2 is connected to the second terminal b of the RF circuit 80, and the other end serves as the antenna connection terminal L1 for connection to the antenna.

[0077] If the main RF circuit and the antenna matching circuit in RF circuit 80 are in a connected state, the detection point T can be connected to the power supply terminal VCC through the second RF choke RFC2 and the pull-up resistor R, and also to the ground terminal through the second RF choke RFC2, RF circuit 80, and the first RF choke RFC1. Since the DC-passing device provides a DC path, the voltage at detection point T in this case is essentially equal to the voltage at the ground terminal, which is a low level. If the main RF circuit and the antenna matching circuit in RF circuit 80 are in a disconnected state, the detection point T can only be connected to the power supply terminal VCC through the second RF choke RFC2 and the pull-up resistor R. In this case, the voltage at detection point T is essentially equal to the voltage at the power supply terminal VCC, which is a high level.

[0078] Therefore, by determining the voltage level at detection point T, the detection circuit can determine the current connection state between the main RF circuit and the antenna matching circuit in the RF circuit, that is, determine the current connection state of the RF circuit. In this embodiment, the output signal of the detection circuit is input to the processor of the communication device, allowing the processor to determine the current connection state of the RF circuit based on the output signal of the detection circuit.

[0079] It should be understood that, although Figure 8 In the RF circuit 80, terminals a and b are in an open state, but this does not mean that the RF circuit 80 can only be in an open state. In some other scenarios, terminals a and b may also be in a connected state.

[0080] This embodiment also provides another communication device; please refer to [link / reference]. Figure 9 The communication device 90 includes a processor 91, a memory 92, and a communication bus 93 for connecting the processor 91 and the memory 92. It is understood that the communication device 90 may also include other devices not shown, such as radio frequency circuits, a camera, and a display screen. Figure 9 The memory 92 can be the aforementioned storage medium storing the radio frequency compensation control program. The processor 91 can read the radio frequency compensation control program, compile it, and execute it to implement the radio frequency compensation control method described in the foregoing embodiments.

[0081] The processor 91 determines the current connection state of the radio frequency (RF) circuit of the communication device 90, and then performs RF compensation on the communication device based on the connection state. In this embodiment, RF compensation includes at least one of power compensation and matching compensation. The RF circuit includes a main RF circuit and an antenna matching circuit, and the connection state is the connection state between the main RF circuit and the antenna matching circuit.

[0082] In some examples of this embodiment, the processor 91 can determine the connection status of the radio frequency circuit based on the input information received at the input unit of the communication device 90. For example, when a tester controls the radio frequency circuit of the communication device to be in a disconnected state, they can input information through the input unit to inform the communication device that its radio frequency circuit is currently in a disconnected state. Alternatively, when a user controls the radio frequency circuit of the communication device to be in a connected state, they can input information through the input unit to inform the communication device that its radio frequency circuit is currently in a connected state.

[0083] In some examples of this embodiment, the communication device further includes a detection circuit for detecting the current connection status of the radio frequency circuit in the communication device. For example, please refer to [link to relevant documentation].
