Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are 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.
The first embodiment is as follows:
at present, the radio frequency circuit of the communication device is generally divided into two parts, one part is the main radio frequency circuit, and the other part is the antenna matching circuit. When the communication equipment works normally or is in an OTA (Over the Air) scene, the main radio frequency circuit is connected with the antenna matching circuit through a radio frequency cable, when the cable connection test is carried out on the communication equipment, the connection between the main radio frequency circuit and the antenna matching circuit is disconnected, the input end of the main radio frequency circuit is connected with the output end of the main radio frequency circuit, and the output end of the main radio frequency circuit is connected to an external instrument. However, in the related art, the communication device operates with the same radio frequency transceiving performance in the two scenarios, which makes it difficult for the radio frequency transceiving performance to meet the requirements of the scenario in which the communication device is located.
In order to solve the problem in the related art that the communication device always operates with the same radio frequency transceiving performance in different working scenes, so that the radio frequency transceiving performance of the communication device is difficult to meet the requirements of the working scene, the embodiment provides a radio frequency compensation control method, please refer to a flowchart of the radio frequency compensation control method shown in fig. 1:
s102: and determining the current connection state of the radio frequency circuit of the communication equipment.
The radio frequency circuit comprises a main radio frequency circuit and an antenna matching circuit, wherein the main radio frequency circuit is generally arranged on one side of a main board of the communication equipment, and the antenna matching circuit is arranged on one side of a sub-board of the communication equipment. Usually, the main board and the sub-board are two independent boards, and the main board refers to a board where main components of the communication device are located, for example, a board where a processor of the communication device is located is the main board. And a daughter board is a board used to deploy a device that performs a certain function in a communication apparatus. 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, and includes two states, i.e. a connection state and a disconnection state:
referring to fig. 2, in the connected state, the main rf circuit 21 is connected to the antenna matching circuit 22. In fig. 2, 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 should be noted that fig. 2 shows a schematic diagram of the connection between the main rf circuit and each end of the antenna matching circuit, rather than the specific structure of the main rf circuit and the antenna matching circuit. Therefore, in practice, the first terminal C of the main rf circuit 21 is not directly connected to the second terminal B of the antenna matching circuit 22, and other devices are also included therebetween.
Fig. 3 shows a schematic diagram of the connection between the main rf circuit 21 and each end of the antenna matching circuit 22 when the rf circuit is in the off state, and it can be seen from fig. 3 that, in the off state, the first end C of the main rf circuit 21 and the second end a of the antenna matching circuit 22 are in the off state, and at the same time, the first end C of the main rf circuit 21 and the third end a are connected. Normally, the third terminal a is also connected to an external test meter.
In some examples of the embodiment, the connection state of the radio frequency circuit of the communication device may be determined based on an input to the communication device by a user or a tester, for example, after the tester controls the radio frequency circuit of the communication device in the disconnection state, the tester may inform the communication device that the radio frequency circuit thereof is currently in the disconnection state by inputting information. Alternatively, after the user controls the rf circuit of the communication device to be in the connected state, the user may inform the communication device that the rf circuit is currently in the connected state by inputting information. In this case, the communication device may determine the current connection state of the radio frequency circuit based on the input information.
In some other examples of this embodiment, the communication device may determine the current connection status of the radio frequency circuit by the detection circuit. Please refer to fig. 4, which illustrates a schematic diagram of a detection circuit for detecting a connection state of a radio frequency circuit: the detection circuit comprises a detection point T, a pull-up resistor R, a blocking device and a straight device.
The dc blocking device is used to block the direct current from passing through, so as to prevent the direct current in the rf detection circuit from affecting the adjacent devices outside the rf circuit 40. The "adjacent devices" refer to devices in the communication device that are connected to the rf circuit 40 and jointly implement the rf transceiving function with the rf circuit 40, and it can be understood that, in general, one end of the rf circuit 40 will be connected to the rf transceiver of the communication device, and the other end will be connected to the antenna, and the three devices jointly implement the rf transceiving function of the communication device, so in this case, the antenna and the rf transceiver can be referred to as two adjacent devices of the rf circuit 40.
The through device can be used for direct current to pass through, and meanwhile, the radio frequency signal cannot be influenced.
In some examples of the present embodiment, the dc blocking device includes a first dc blocking device 411 and a second dc blocking device 412, and the pass device includes a first pass device 421 and a second pass device 422, and the connection relationship and the operation principle between the detection circuit and the rf circuit 40 are explained below with reference to fig. 4:
the first end of the pull-up resistor R is connected to the power supply terminal VCC, the second end is connected to the first end a of the rf circuit 40, and the second end b of the rf circuit 40 is connected to the ground terminal GND through the first pass-through device 421. The detection point T is connected to the first end of the rf circuit 40 through the second pass-through device 422, one end of the first blocking device 411 is connected to the first end a of the rf circuit 40, and the other end is used as a first external neighboring device connection end L1 for being connected to the first external neighboring device. The second dc blocking device 412 has one end connected to the second end b of the rf circuit 40, and the other end serving as a second neighboring device connection end L2 for connecting to a second neighboring device. In this embodiment, one of the first and second peripheral devices is an antenna, and the other is a radio frequency transceiver.
In the embodiment, if the detection point T detects the first level, the radio frequency circuit is determined to be in a connected state currently; if the detection point T detects a second level, the radio frequency circuit is determined to be in a disconnection state, and the second level is higher than the first level, so that when the radio frequency circuit is in a connection state, the detection point T detects a low level, and when the radio frequency circuit is in a disconnection state, the detection point T detects a high level:
it will be appreciated that the first end a of the second pass device 422 is in an "open circuit" state with the first externally adjacent device connection end L1 due to the first blocking device 411. Similarly, under the action of the second dc blocking device 412, the second end b of the rf circuit 40 is also in an "open circuit" state with the second neighboring device connection terminal L2. In this case, if the main rf circuit and the antenna matching circuit in the rf circuit 40 are connected, the detection point T can be connected to the power supply terminal VCC through the second pass-through device 422 and the pull-up resistor R, and can be connected to the ground terminal GND through the second pass-through device 422, the rf circuit 40 and the first pass-through device 421. Since the pass-through device is connected to the pass-through current path, the voltage at the detection point T in this case is substantially equal to the voltage at the ground, and is low. If the main rf circuit in the rf circuit 40 is disconnected from the antenna matching circuit, the detection point T can only be connected to the power supply terminal VCC through the second pass-through device 422 and the pull-up resistor R, and at this time, the electrode of the detection point T is substantially equal to the voltage of the power supply terminal VCC and belongs to a high level.
Therefore, 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 by determining the voltage at the detection point T. In this embodiment, the output signal of the detection circuit is input into the processor of the communication device, so that the processor determines the current connection state of the rf circuit 40 according to the output signal of the detection circuit.
It should be noted that although both ends a and b are in the on state in the rf circuit 40 in fig. 4, this does not mean that the rf circuit 40 can only be in the on state, and in other scenarios, both ends a and b may also be in the off state.
In some examples of this embodiment, the detection circuit further includes a third dc blocking device, please refer to another schematic diagram of the detection circuit shown in fig. 5 for detecting the connection state of the rf circuit:
in fig. 5, the blocking device includes, in addition to the first blocking device 411 and the second blocking device 412, a third blocking device 413, and the third blocking device 413 is capable of absorbing rf signals from an antenna or from an rf transceiver. One end of the third blocking device 413 is connected to the detection point T, and the other end is connected to the ground GND.
In some examples of the present embodiment, the blocking device may include a capacitor device or a high resistance device, and in some examples, the first blocking device 411, the second blocking device 412, and the third blocking device 413 may all be capacitor devices or all be high resistance devices. In some other examples of this embodiment, some of the first blocking device 411, the second blocking device 412, and the third blocking device 413 may be capacitor devices, and other parts may be high-resistance devices.
In some examples of the present embodiment, the pass-through device may be an inductor, for example, in some examples of the present embodiment, the first pass-through device 421 and the second pass-through device 422 are both Radio Frequency Chokes (RFC). The rf choke is a large inductor, and because the inductive reactance Xl is 2 pi fL, the RFC dc current path can be seen, and the rf choke is open-circuited to high-frequency ac.
It should be understood that although both ends a and b are in the off state in the rf circuit 50 in fig. 5, this does not mean that the rf circuit 50 can only be in the off state, and in other scenarios, both ends a and b may be in the on state.
S104: and performing radio frequency compensation on the communication equipment according to the connection state.
After the communication equipment determines the connection state of the radio frequency circuit, radio frequency compensation can be carried out according to the radio frequency connection state, and different radio frequency compensation can be correspondingly carried out in different connection states. In this embodiment, the radio frequency compensation includes at least one of power compensation and matching compensation. In this embodiment, the matching compensation means that a matching circuit is provided for the rf circuit, or the rf circuit is connected to the matching circuit, and the matching circuit is an impedance matching circuit.
For example, in some examples, the state of the radio frequency circuit may not affect the selection of the matching circuit of the communication device, but when the radio frequency circuit is in the connected state, the communication device may perform transmission power compensation by using a first power compensation strategy, and when it is determined that the radio frequency circuit is in the disconnected state, the communication device may perform transmission power compensation by using a second power compensation strategy, where the first power compensation strategy is different from the second power compensation strategy, in some examples of this embodiment, the power compensated by the first power compensation strategy may be higher than the power compensated by the second power compensation strategy, and in other examples, the power compensated by the first power compensation strategy may also be lower than the power compensated by the second power compensation strategy.
In other examples, the state of the rf circuit may not affect the selection of the power compensation policy for the communication device, but the state of the rf circuit may affect the policy for matching compensation for the communication device.
In still other examples, the state of the rf circuit is different, and the transmit power compensation strategy and the selection of the matching circuit are different.
According to the radio frequency compensation control method provided by the embodiment of the invention, different radio frequency compensations can be carried out based on different connection states of the radio frequency circuit, so that the communication equipment has different radio frequency transceiving performances in different working scenes, and the radio frequency transceiving performances of the communication equipment are ensured to meet the requirements of the working scenes where the communication equipment is located.
In addition, in the radio frequency compensation control method provided in this embodiment, the communication device may determine the level at the detection point through a simple detection circuit, so as to identify the current state of the radio frequency connection circuit based on the level at the detection point, and complete identification of the connection state of the radio frequency circuit on the basis of not significantly increasing the cost of the communication device and the burden of a tester or a user of the communication device, which is beneficial to improving the user experience of the communication device.
Example two:
the present embodiment provides a communication device, please refer to a schematic structural diagram of the communication device shown in fig. 6:
the communication device 60 includes: a state determining unit 602 and a compensation control unit 604, where the state determining unit 602 is configured to determine a current connection state of a radio frequency circuit of the communication device, where the radio frequency circuit includes a main radio frequency circuit and an antenna matching circuit, and the connection state is a connection state between the main radio frequency circuit and the antenna matching circuit; and the compensation control unit 604 is configured to perform radio frequency compensation on the communication device according to the connection state, where the radio frequency compensation includes at least one of power compensation and matching compensation.
In some examples of the present embodiment, the state determination unit 602 includes a detection circuit for detecting a current connection state of a radio frequency circuit in the communication device.
In some examples of the present embodiment, the detection circuit includes a detection point T, a pull-up resistor R, a dc blocking device, and a dc pass device. Please continue with fig. 4: the blocking device is used for blocking direct current from passing through, and the direct current in the radio frequency detection circuit is prevented from influencing adjacent devices outside the radio frequency circuit 40. The "adjacent devices" refer to devices in the communication device that are connected to the rf circuit 40 and jointly implement the rf transceiving function with the rf circuit 40, and it can be understood that, in general, one end of the rf circuit 40 will be connected to the rf transceiver of the communication device, and the other end will be connected to the antenna, and the three devices jointly implement the rf transceiving function of the communication device, so that the antenna and the rf transceiver are two adjacent devices of the rf circuit 40.
The through device can be used for direct current to pass through, and meanwhile, the radio frequency signal cannot be influenced.
In some examples of the present embodiment, the dc blocking device includes a first dc blocking device 411 and a second dc blocking device 412, and the pass device includes a first pass device 421 and a second pass device 422, and the connection relationship and the operation principle between the detection circuit and the rf circuit 40 are explained below with reference to fig. 4:
a first end of the pull-up resistor R is connected to the power supply terminal VCC, a second end is connected to the first end of the rf circuit 40, and a second end of the rf circuit 40 is connected to the ground terminal GND through the first pass-through device 421. The detection point T is connected to the first end of the rf circuit 40 through the second pass-through device 422, one end of the first blocking device 411 is connected to the first end of the rf circuit 40, and the other end is used as a first external neighboring device connection end L1 for connecting to the first external neighboring device. The second dc blocking device 412 has one end connected to the second end of the rf circuit 40, and the other end serving as a second neighboring device connection terminal L2 for connecting to a second neighboring device. In this embodiment, one of the first and second peripheral devices is an antenna, and the other is a radio frequency transceiver.
It will be appreciated that the first blocking device 411 causes the second pass device 422 to be in an "open circuit" state with the first end of the first adjacent device connection terminal L1. Similarly, under the action of the second dc blocking device 412, the second end of the rf circuit 40 is also in an "open circuit" state with the second neighboring device connection terminal L2. 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 pass-through device 422 and the pull-up resistor R, and can be connected to the ground terminal through the second pass-through device 422, the rf circuit 40 and the first pass-through device 421. Since the pass-through device is connected to the pass-through current path, the voltage at the detection point T in this case is substantially equal to the voltage at the ground, and is low. If the main rf circuit in the rf circuit 40 is disconnected from the antenna matching circuit, the detection point T can only be connected to the power supply terminal VCC through the second pass-through device 422 and the pull-up resistor R, and at this time, the electrode of the detection point T is substantially equal to the voltage of the power supply terminal VCC and belongs to a high level.
Therefore, 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 by determining the voltage at the detection point T. In this embodiment, the output signal of the detection circuit is input into the processor of the communication device, so that the processor determines the current connection state of the rf circuit 40 according to the output signal of the detection circuit.
In some examples of this embodiment, the detection circuit further includes a third dc blocking device, please continue with fig. 5: the blocking device includes a third blocking device 413 besides the first blocking device 411 and the second blocking device 412, one end of the third blocking device 413 is connected to the detection point T, and the other end of the third blocking device 413 is connected to the ground GND.
In some examples of the present embodiment, the blocking device may include a capacitor device or a high resistance device, and in some examples, the first blocking device 411, the second blocking device 412, and the third blocking device 413 may all be capacitor devices or all be high resistance devices. In some other examples of this embodiment, some of the first blocking device 411, the second blocking device 412, and the third blocking device 413 may be capacitor devices, and other parts may be high-resistance devices.
In some examples of the present embodiment, the pass-through device may be an inductor, for example, in some examples of the present embodiment, the first pass-through device 421 and the second pass-through device 422 are both rf chokes.
Please refer to fig. 7, which is a schematic diagram illustrating a principle of detecting the connection state of the rf circuit by the detection circuit: the detection circuit comprises a detection point T, a pull-up resistor R0, a blocking device (a first blocking device C1, a second blocking device C2 and a third blocking device C3) and a pass device (a first radio frequency choke RFC1 and a first radio frequency choke RFC 2).
The first end of the pull-up resistor R0 is connected to the power supply terminal VCC, the second end is connected to the first end a of the rf circuit 70, and the second end b of the rf circuit 70 is connected to the ground terminal GND through the first rf choke RFC 1. The detection point T is connected to the first end 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 end a of the rf circuit 70, and the other end is used as an antenna connection terminal L1 for connecting to an antenna. The second dc blocking device C2 has one end connected to the second end b of the rf circuit 70, and the other end serving as a transceiver connection end L2 for connecting to an rf transceiver.
If the main rf circuit in the rf circuit 70 is connected to the antenna matching circuit, 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 can be connected to the ground terminal through the second rf choke RFC2, the rf circuit 70 and the first rf choke RFC 1. Since the pass-through device is connected to the pass-through current path, the voltage at the detection point T in this case is substantially equal to the voltage at the ground, and is low. If the main rf circuit in the rf circuit 70 is disconnected from the antenna matching circuit, 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, and at this time, the electrode at the detection point T is substantially equal to the voltage of the power supply terminal VCC and belongs to a high level.
It should be noted that although the two terminals a and b of the rf circuit 70 in fig. 7 are in the connected state, this does not mean that the rf circuit 70 can only be in the connected state, and in other scenarios, the two terminals a and b may also be in the disconnected state.
Please refer to fig. 8, which illustrates a schematic diagram of a detection circuit for detecting a connection state of a rf circuit: the detection circuit comprises a detection point T, a pull-up resistor R0, a blocking device (a first blocking device C1, a second blocking device C2 and a third blocking device C3) and a pass device (a first radio frequency choke RFC1 and a first radio frequency choke RFC 2).
The first end of the pull-up resistor R0 is connected to the power supply terminal VCC, the second end is connected to the first end a of the rf circuit 80, and the second end b of the rf circuit 80 is connected to the ground terminal GND through the first rf choke RFC 1. The detection point T is connected to the first end 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 end a of the rf circuit 80, and the other end is used as a transceiver connection terminal L2 for connecting to the rf transceiver. The second dc blocking device C2 has one end connected to the second end b of the rf circuit 80 and the other end serving as an antenna connection end L1 for connecting to an antenna.
If the main rf circuit in the rf circuit 80 is connected to the antenna matching circuit, 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 can be connected to the ground terminal through the second rf choke RFC2, the rf circuit 80, and the first rf choke RFC 1. Since the pass-through device is connected to the pass-through current path, the voltage at the detection point T in this case is substantially equal to the voltage at the ground, and is low. If the main radio frequency circuit in the radio frequency circuit 80 is disconnected from the antenna matching circuit, the detection point T can only be connected with the power supply terminal VCC through the second radio frequency choke RFC2 and the pull-up resistor R, and at this time, the electrode of the detection point T is substantially equal to the voltage of the power supply terminal VCC and belongs to a high level.
Therefore, the detection circuit can determine the current connection state between the main radio frequency circuit and the antenna matching circuit in the radio frequency circuit by determining the voltage of the detection point T, that is, the current connection state of the radio frequency circuit. In this embodiment, the output signal of the detection circuit is input into the processor of the communication device, so that the processor determines the current connection state of the rf circuit according to the output signal of the detection circuit.
