Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of communication technology, and particularly to a communication device, a control method, a base station, and a computer-readable storage medium. Background Technology

[0002] Antenna calibration technology is one of the core technologies of beamforming and a prerequisite for realizing the advantages of massive MIMO (Multiple Input Multiple Output) technology. For Frequency Division Duplex (FDD) systems, due to the different operating frequencies of the transmit and receive links, traditional schemes cannot use the transmit link to send calibration sequences for the receive frequency band, nor can the receive link be used to receive calibration sequences for the transmit frequency band. Therefore, for signal calibration of the receive link, an additional transmit module is needed to send calibration sequences consistent with the receive frequency band; for signal calibration of the transmit link, an additional receive module is needed to receive calibration sequences consistent with the transmit frequency band.

[0003] Therefore, the need for additional transmitter and receiver modules inevitably necessitates the introduction of additional analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). The introduction of ADCs and DACs leads to increased layout area, higher costs, increased pin pressure on logic devices, and increased power supply requirements. Summary of the Invention

[0013] The logic module is used to send a first correction signal to the transmit link and control the correction frequency conversion module to work so that the first correction signal is modulated to a second frequency point by the transmit link, so that the first correction signal is transmitted to the antenna module through the coupling module, and the first correction signal at the second frequency point received by the receiving link from the antenna module is obtained to perform radio frequency signal correction.

[0014] And / or:

[0015] The device is used to send a second correction signal to the transmit link so that the second correction signal is modulated to a first frequency point by the transmit link, so that the second correction signal is transmitted to the coupling module through the antenna module, and to control the correction frequency conversion module to work so that the receive link modulates the second correction signal at the first frequency point received from the coupling module, and to obtain the second correction signal received by the receive link for radio frequency signal correction.

[0016] Secondly, embodiments of the present invention provide a control method for a communication device. The communication device includes a transmitting link for transmitting a radio frequency signal at a first frequency, a receiving link for receiving a radio frequency signal at a second frequency, an antenna module for transmitting and receiving radio frequency signals, a coupling module, and a correction and frequency conversion module.

[0021] And / or:

[0022] A second correction signal is sent to the transmit link so that the second correction signal is modulated to a first frequency point by the transmit link, and the second correction signal is transmitted to the coupling module through the antenna module;

[0023] The correction frequency conversion module is controlled to operate so that the receiving link modulates the second correction signal at the first frequency point received from the coupling module;

[0024] The second correction signal received by the receiving link is acquired to perform radio frequency signal correction.

[0025] Thirdly, embodiments of the present invention provide a base station, including the communication equipment described in the first aspect above; or including:

[0026] The device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the control method for the communication device described in the second aspect above.

[0027] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer-executable instructions for performing the control method of the communication device as described in the second aspect above.

[0028] This invention includes a communication device comprising a logic module, a transmit link, a receive link, an antenna module, a coupling module, and a correction / conversion module.

The coupling module connects to the transmit link, the receive link, and the antenna module. The correction / conversion module is located on the transmit link and / or the receive link. The logic module is connected to the transmit link, the receive link, and the correction / conversion module. When the communication device needs to send communication service data, the communication service data signal is transmitted from the logic module to the transmit link, modulated to the first frequency by the transmit link, and then transmitted via the antenna module. When the communication device needs to receive externally transmitted communication service data, the antenna module receives the RF signal at the second frequency and transmits it to the receive link, which then transmits the received RF signal at the second frequency to the logic module. According to the solution provided in the embodiments of the present invention, a correction frequency conversion module is set in the transmit link and / or the receive link. When the correction frequency conversion module is set in the transmit link, the transmit link can transmit a first correction signal at a second frequency point after the correction frequency conversion module is controlled to work, and the receive link can receive the first correction signal at the second frequency point and transmit it to the logic module for radio frequency signal correction. When the correction frequency conversion module is set in the receive link, the transmit link can directly transmit a second correction signal at a first frequency point, and the receive link can receive the second correction signal at the first frequency point and transmit it to the logic module for radio frequency signal correction. That is, radio frequency signal correction can be achieved by multiplexing the radio frequency link without setting up additional transmit modules, receive modules and ADC / DAC devices, avoiding problems such as increased layout area, increased cost, increased pin pressure of logic devices and increased power supply configuration.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0047] This invention provides a communication device, a control method, a base station, and a computer-readable storage medium. The communication device includes a logic module, a transmit link, a receive link, an antenna module, a coupling module, and a correction frequency conversion module. The transmit link is used to transmit radio frequency signals at a first frequency, and the receive link is used to receive radio frequency signals at a second frequency. The antenna module is used to transmit and receive radio frequency signals and is connected to both the transmit link and the receive link. The coupling module is connected to the transmit link, the receive link, and the antenna module. The correction frequency conversion module is disposed on the transmit link and / or the receive link. The logic module is connected to the transmit link, the receive link, and the correction frequency conversion module. By setting up correction conversion modules in the transmit and / or receive links, when the correction conversion module is set in the transmit link, the transmit link can transmit the first correction signal at the second frequency point after the correction conversion module is activated, and the receive link can receive the first correction signal at the second frequency point and transmit it to the logic module for RF signal correction. When the correction conversion module is set in the receive link, the transmit link can directly transmit the second correction signal at the first frequency point, and the receive link can receive the second correction signal at the first frequency point and transmit it to the logic module for RF signal correction. In other words, RF signal correction can be achieved by multiplexing RF links without setting up additional transmit modules, receive modules, and ADC / DAC devices, thus avoiding problems such as increased layout area, increased cost, increased pin pressure of logic devices, and increased power supply configuration.

[0048] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, Figure 1 This is a schematic diagram of a communication device provided by an embodiment of the present invention, which can realize the correction of radio frequency signals by multiplexing radio frequency links.

[0050] like Figure 1As shown, the communication device includes: a logic module, a transmit link, a receive link, an antenna module, a coupling module, and a correction / conversion module; wherein, the transmit link is used to transmit radio frequency signals at a first frequency; the receive link is used to receive radio frequency signals at a second frequency; the antenna module is used to transmit and receive radio frequency signals, and the antenna module is connected to both the transmit link and the receive link; the coupling module is connected to the transmit link, the receive link, and the antenna module; the logic module is connected to both the transmit link, the receive link, and the correction / conversion module; the correction / conversion module is located on the transmit link and / or on the receive link. Figure 1 The correction inverter module is not shown in the diagram.

[0051] When the correction frequency conversion module is set in the transmit link, the logic module is used to send the first correction signal to the transmit link and control the correction frequency conversion module to work so that the first correction signal is modulated to the second frequency point by the transmit link, so that the first correction signal is transmitted to the antenna module through the coupling module. The logic module obtains the first correction signal of the second frequency point received by the antenna module from the receive link to perform radio frequency signal correction, thereby realizing uplink antenna correction.

[0052] When the correction frequency conversion module is set in the receiving link, the logic module sends a second correction signal to the transmitting link so that the second correction signal is modulated to the first frequency point by the transmitting link. The second correction signal is then transmitted to the coupling module through the antenna module, and the correction frequency conversion module is controlled to work so that the receiving link modulates the second correction signal at the first frequency point received from the coupling module. The logic module obtains the second correction signal received by the receiving link to perform radio frequency signal correction, thereby realizing downlink antenna correction.

[0053] In one embodiment, reference is made to Figure 2 The transmission link includes a digital-to-analog converter module, an up-conversion module, and a first switching switch. A correction frequency conversion module is installed in the transmission link. The correction frequency conversion module and the up-conversion module are connected to form a first frequency conversion component. Specifically, the logic module, the digital-to-analog converter module, the first frequency conversion component, the first switching switch, and the antenna module are connected in sequence. The first switching switch is also connected to the coupling module and the logic module. The logic module is specifically used for: sending a first correction signal to the transmission link; controlling the operation of the correction frequency conversion module so that the first correction signal is modulated to a second frequency point by the transmission link; controlling the first switching switch to connect the first frequency conversion component and the coupling module so that the first correction signal is transmitted to the antenna module through the first switching switch and the coupling module; and acquiring the first correction signal of the second frequency point received by the receiving link from the antenna module to perform radio frequency signal correction.

[0054] In this embodiment, the transmission link can be multiplexed by setting a correction frequency conversion module. Specifically, when the communication device needs to send communication service data, the communication service data signal is transmitted from the logic module to the transmission link. At this time, the correction frequency conversion module is bypassed, and the communication service data signal is modulated to the first frequency point by the digital-to-analog converter module and the up-conversion module of the transmission link, and then transmitted through the antenna module. When radio frequency signal correction is required, the first correction signal is transmitted from the logic module to the transmission link, and is modulated to the second frequency point by the digital-to-analog converter module, the correction frequency conversion module, and the up-conversion module. The first correction signal then passes through the first switching switch, the coupling module, and the antenna module in sequence to reach the receiving link. The receiving link modulates the received first correction signal at the second frequency point and transmits it to the logic module for radio frequency signal correction, thereby realizing uplink antenna correction.

[0055] In this embodiment, the correction frequency conversion module is located at the back end of the digital-to-analog conversion module. Therefore, the correction frequency conversion module converts the analog signal and can be implemented using an analog mixer.

[0056] in addition, Figure 2 The order of the correction converter module and the upconversion module in the first frequency conversion component shown can be interchanged. Furthermore, in practical applications, they can be implemented using the same components, differing only in the amplitude of their analog signal conversion. It should be further noted that while the correction converter module and the upconversion module constitute the first frequency conversion component, there is no limitation that they must be integrated into a single device. The correction converter module and the upconversion module can be two independent modules, or they can be integrated into other devices. For example, the upconversion module can be integrated with a digital-to-analog converter module into a single device.

[0057] It is understandable that an amplification module can be set between the first switching switch and the antenna module to amplify the signal that needs to be transmitted through the antenna module before it is transmitted to the outside.

[0058] In one embodiment, reference is made to Figure 3The transmission link includes a digital-to-analog converter module, an up-conversion module, and a first switching switch. A correction frequency conversion module is installed in the transmission link. The correction frequency conversion module and the up-conversion module are connected to form a first frequency conversion component. Specifically, the logic module, the first frequency conversion component, the digital-to-analog converter module, the first switching switch, and the antenna module are connected in sequence. The first switching switch is also connected to the coupling module and the logic module. The logic module is specifically used for: sending a first correction signal to the transmission link; controlling the operation of the correction frequency conversion module so that the first correction signal is modulated to a second frequency point by the transmission link; controlling the first switching switch to connect the digital-to-analog converter module and the coupling module so that the first correction signal is transmitted to the antenna module through the first switching switch and the coupling module; and acquiring the first correction signal of the second frequency point received by the receiving link from the antenna module to perform radio frequency signal correction.

[0059] This embodiment and Figure 2 The difference in the illustrated embodiment is that the correction frequency conversion module is located in front of the digital-to-analog converter module. Therefore, the correction frequency conversion module performs frequency conversion on the digital signal and can be implemented using a digital mixer, such as a numerically controlled oscillator (NCO). Similarly, Figure 3 The order of the correction frequency converter module and the up-frequency converter module in the first frequency conversion component shown can be interchanged. The correction frequency converter module and the up-frequency converter module constitute the first frequency conversion component. There is no limitation that the correction frequency converter module and the up-frequency converter module need to be integrated into one device. The correction frequency converter module and the up-frequency converter module can be two independent modules, or they can be integrated into other devices. For example, the up-frequency converter module can be integrated with the digital-to-analog converter module into one device. The remaining working principles of the communication device in this embodiment are the same as... Figure 2 The same applies, so I won't elaborate further here.

[0060] In one embodiment, reference is made to Figure 4 The receiving link includes a second switching switch, a down-conversion module, and an analog-to-digital converter module. A correction conversion module is located in the receiving link. The correction conversion module and the down-conversion module are connected to form a second conversion component. Specifically, the antenna module, the second switching switch, the second conversion component, the analog-to-digital converter module, and the logic module are connected in sequence. The second switching switch is also connected to the coupling module and the logic module. The logic module is specifically used for: sending a second correction signal to the transmitting link so that the second correction signal is modulated to a first frequency point, so that the second correction signal is transmitted to the coupling module through the antenna module; controlling the second switching switch to connect the coupling module and the second conversion component so that the receiving link receives the second correction signal of the first frequency point from the coupling module through the second switching switch; controlling the correction conversion module to work so that the receiving link modulates the received second correction signal of the first frequency point and transmits it to the logic module; and acquiring the second correction signal received by the receiving link to perform radio frequency signal correction.

[0061] In this embodiment, the multiplexing of the receiving link can be achieved by setting a correction frequency conversion module in the receiving link. Specifically, when the communication device needs to receive communication service data sent from the outside, the antenna module transmits the received communication service data signal at the first frequency point to the transmitting link. At this time, the correction frequency conversion module is bypassed, and the communication service data signal at the first frequency point is modulated by the down-conversion module and the analog-to-digital conversion module of the receiving link and then transmitted to the logic module. When radio frequency signal correction is required, the second correction signal is transmitted from the logic module to the transmitting link and modulated to the first frequency point by the transmitting link. The second correction signal then passes through the antenna module, the coupling module, and the second switching switch in sequence to reach the receiving link. At this time, the correction frequency conversion module is controlled to work. The second correction signal is then modulated by the correction frequency conversion module, the down-conversion module, and the analog-to-digital conversion module and then transmitted to the logic module to perform radio frequency signal correction, thereby realizing downlink antenna correction.

[0062] In this embodiment, the correction frequency conversion module is located at the front end of the analog-to-digital conversion module. Therefore, the correction frequency conversion module converts the analog signal and can be implemented using an analog mixer.

[0063] in addition, Figure 4 The order of the correction converter module and the downconverter module in the second frequency conversion component shown can be interchanged. Furthermore, in practical applications, they can be implemented using the same components, differing only in the amplitude of their analog signal conversion. It should be further noted that the correction converter module and the downconverter module constitute the second frequency conversion component, but this does not imply that they must be integrated into a single device. The correction converter module and the downconverter module can be two independent modules, or they can be integrated into other devices; for example, the downconverter module can be integrated with the analog-to-digital converter module into a single device.

[0064] It is understandable that an amplification module can be installed between the antenna module and the second switching switch to amplify the signal received by the antenna module before transmitting it to the receiving link.

[0065] In one embodiment, reference is made to Figure 5The receiving link includes a second switching switch, a down-conversion module, and an analog-to-digital converter module. A correction conversion module is located within the receiving link. The correction conversion module and the down-conversion module are connected to form a second conversion component. Specifically, the antenna module, the second switching switch, the analog-to-digital converter module, the second conversion component, and the logic module are connected sequentially. The second switching switch is also connected to the coupling module and the logic module. The logic module is specifically used for: sending a second correction signal to the transmitting link so that the second correction signal is modulated to a first frequency point, allowing the second correction signal to be transmitted to the coupling module through the antenna module; controlling the second switching switch to connect the coupling module and the down-conversion module so that the receiving link receives the second correction signal at the first frequency point from the coupling module through the second switching switch; controlling the correction conversion module to operate so that the receiving link modulates the received second correction signal at the first frequency point and transmits it to the logic module; and acquiring the second correction signal received by the receiving link to perform radio frequency signal correction.

[0066] This embodiment and Figure 4 The difference in the illustrated embodiment is that the correction frequency conversion module is located after the analog-to-digital conversion module. Therefore, the correction frequency conversion module performs frequency conversion on the digital signal and can be implemented using a digital mixer, such as a numerically controlled oscillator (NCO). Similarly, Figure 5 The order of the correction converter module and the downconverter module in the second frequency conversion component shown can be interchanged. The correction converter module and the downconverter module constitute the second frequency conversion component. There is no limitation that the correction converter module and the downconverter module need to be integrated into one device. The correction converter module and the downconverter module can be two independent modules, or they can be integrated into other devices. For example, the downconverter module can be integrated with the analog-to-digital converter module into one device. The remaining working principles of the communication device in this embodiment are the same as... Figure 4 The same applies, so I won't elaborate further here.

[0067] In one embodiment, reference is made to Figure 6 The communication equipment includes a logic module, a transmit link, a receive link, an antenna module, a coupling module, a first correction frequency conversion module, a second correction frequency conversion module, and a third switching switch; wherein:

[0068] The transmission link includes a digital-to-analog converter module, an up-conversion module, and a first switching switch. A first correction frequency conversion module is installed in the transmission link. The first correction frequency conversion module and the up-conversion module are connected to form a first frequency conversion component. The logic module, the digital-to-analog converter module, the first frequency conversion component, the first switching switch, and the antenna module are connected in sequence.

[0069] The receiving link includes a second switching switch, a down-conversion module, and an analog-to-digital conversion module. A second correction frequency conversion module is installed in the receiving link. The second correction frequency conversion module and the down-conversion module are connected to form a second frequency conversion component. The antenna module, the second switching switch, the second frequency conversion component, the analog-to-digital conversion module, and the logic module are connected in sequence.

[0070] The third switch is connected to the first switch, the second switch, and the coupling module respectively; the first calibration frequency converter module, the second calibration module, the first switch, the second switch, and the third switch are all connected to the logic module;

[0071] The logic module is specifically used for: sending a first correction signal to the transmit link; controlling the first correction frequency conversion module to operate so that the first correction signal is modulated to a second frequency point by the transmit link; controlling the first switching switch to connect the first frequency conversion component and the third switching switch, and controlling the third switching switch to connect the first switching switch and the coupling module so that the first correction signal is transmitted to the antenna module through the first switching switch, the third switching switch and the coupling module; and acquiring the first correction signal at the second frequency point received from the antenna module by the receive link to perform radio frequency signal correction.

[0072] The device is configured to: send a second correction signal to the transmit link so that the second correction signal is modulated to a first frequency point; control a first switching switch to connect the first frequency conversion component and the antenna module so that the second correction signal is transmitted to the coupling module through the first switching switch and the antenna module; control a third switching switch to connect the coupling module and the second switching switch; and control the second switching switch to connect the third switching switch and the second frequency conversion component so that the receive link receives the second correction signal of the first frequency point from the coupling module through the second switching switch and the third switching switch; control the second correction frequency conversion module to operate so that the receive link modulates the received second correction signal of the first frequency point and transmits it to the logic module; and acquire the second correction signal received by the receive link to perform radio frequency signal correction.

[0073] In this embodiment, the first correction frequency conversion module is located at the rear end of the digital-to-analog conversion module. Therefore, the correction frequency conversion module converts the analog signal and can be implemented using an analog mixer. In this embodiment, the second correction frequency conversion module is located at the front end of the analog-to-digital conversion module. Therefore, the second correction frequency conversion module converts the analog signal and can be implemented using an analog mixer.

[0074] in addition, Figure 6The order of the first correction frequency converter module and the upper frequency converter module in the first frequency converter component shown can be interchanged. The first correction frequency converter module and the upper frequency converter module constitute the first frequency converter component. There is no requirement that the first correction frequency converter module and the upper frequency converter module need to be integrated into one device. The first correction frequency converter module and the upper frequency converter module can be two independent modules, or they can be integrated into other devices. For example, the upper frequency converter module can be integrated into a digital-to-analog converter module. Similarly, the order of the second correction frequency converter module and the lower frequency converter module in the second frequency converter component can be interchanged. The second correction frequency converter module and the lower frequency converter module constitute the second frequency converter component. There is no requirement that the second correction frequency converter module and the lower frequency converter module need to be integrated into one device. The second correction frequency converter module and the lower frequency converter module can be two independent modules, or they can be integrated into other devices. For example, the lower frequency converter module can be integrated into a digital-to-analog converter module.

[0075] Understandably, the first frequency conversion component can also be located at the front end of the digital-to-analog conversion module. In this case, the first correction frequency conversion module in the first frequency conversion component performs frequency conversion on the digital signal, which can be implemented using a digital mixer, such as a numerically controlled oscillator (NCO). Similarly, the second frequency conversion component can also be located at the back end of the analog-to-digital conversion module. In this case, the second correction frequency conversion module in the second frequency conversion component performs frequency conversion on the digital signal, which can be implemented using a digital mixer, such as a numerically controlled oscillator (NCO).

[0076] In addition, it is understandable that an amplification module can be set between the first switching switch and the antenna module to amplify the signal that needs to be transmitted through the antenna module before it is sent out; similarly, an amplification module can be set between the antenna module and the second switching switch to amplify the signal received by the antenna module before it is transmitted to the receiving link.

[0077] Based on the communication device structure described in the above embodiments, various embodiments of the control method for the communication device are proposed below.

[0078] like Figure 7 As shown, Figure 7 This is a flowchart illustrating a control method for a communication device according to an embodiment of the present invention. This control method can be applied to... Figure 1 The communication device shown in the embodiment does not depict a correction frequency conversion module, which is located in the transmission link. The control method includes, but is not limited to, the following steps:

[0079] Step S710: Send the first correction signal to the transmit link;

[0080] Step S720: Control the operation of the correction frequency conversion module so that the first correction signal is modulated to the second frequency point by the transmission link, so that the first correction signal is transmitted to the antenna module through the coupling module;

[0081] Step S730: Obtain the first correction signal modulated to the second frequency point received by the receiving link from the antenna module, so as to perform radio frequency signal correction.

[0082] In this embodiment, when radio frequency signal correction is required, the first correction signal is transmitted from the logic module to the transmit link. The control correction frequency conversion module is operated so that the first correction signal is modulated to the second frequency point by the transmit link. The first correction signal then passes through the coupling module and the antenna module to reach the receiving link. The receiving link modulates the received first correction signal at the second frequency point and transmits it to the logic module for radio frequency signal correction, thereby realizing uplink antenna correction.

[0083] like Figure 8 As shown, Figure 8 This is a flowchart of a control method for a communication device according to another embodiment of the present invention. This control method can be applied to... Figure 1 The communication device in the illustrated embodiment, where the correction frequency conversion module is not shown in the figure, is located in the receiving link. The control method includes, but is not limited to, the following steps:

[0084] Step S810: Send a second correction signal to the transmit link so that the second correction signal is modulated to the first frequency point by the transmit link, so that the second correction signal is transmitted to the coupling module through the antenna module;

[0085] Step S820: Control the operation of the correction frequency conversion module to enable the receiving link to modulate the second correction signal at the first frequency point received from the coupling module;

[0086] Step S830: Obtain the second correction signal received by the receiving link to perform radio frequency signal correction.

[0087] In this embodiment, when radio frequency signal correction is required, the second correction signal is transmitted from the logic module to the transmit link and modulated to the first frequency point by the transmit link. The second correction signal then passes through the antenna module and the coupling module to reach the receive link. At this time, the control correction frequency conversion module is activated. The second correction signal is then modulated by the receive link and transmitted to the logic module to perform radio frequency signal correction, thereby realizing downlink antenna correction.

[0088] like Figure 9 As shown, Figure 9 This is a flowchart of a control method for a communication device according to another embodiment of the present invention. This control method can be applied to... Figure 2The communication device in the illustrated embodiment includes, but is not limited to, the following steps in its control method:

[0089] Step S910: Send the first correction signal from the digital-to-analog converter module to the transmission link;

[0090] Step S920: Control the operation of the correction frequency converter module so that the first correction signal is modulated to the second frequency point by the transmission link;

[0091] Step S930: Control the first switching switch to connect the first frequency conversion component and the coupling module, so that the first correction signal is transmitted to the antenna module through the first switching switch and the coupling module;

[0092] Step 940: Obtain the first correction signal of the second frequency point received from the antenna module by the receiving link to perform radio frequency signal correction.

[0093] In this embodiment, when radio frequency signal correction is required, the first correction signal is transmitted from the logic module to the transmit link and modulated to the second frequency point by the digital-to-analog converter module, the up-conversion module and the correction frequency conversion module. The first correction signal then passes through the first switching switch, the coupling module and the antenna module in sequence to reach the receive link. The receive link modulates the received first correction signal at the second frequency point and transmits it to the logic module to perform radio frequency signal correction, thereby realizing uplink antenna correction.

[0094] Applied to Figure 3 The control method of the communication equipment in this embodiment is basically the same as the process in this embodiment, except for the following two points: First, in step S910, the first correction signal is sent from the first frequency conversion component to the transmission link, instead of the first correction signal being sent from the digital-to-analog conversion module to the transmission link; Second, in step S930, the first switching switch is connected to the digital-to-analog conversion and coupling module, instead of the first frequency conversion component and the coupling module.

[0095] like Figure 10 As shown, Figure 10 This is a flowchart of a control method for a communication device according to another embodiment of the present invention. This control method can be applied to... Figure 4 The communication device in the illustrated embodiment includes, but is not limited to, the following steps in its control method:

[0096] Step S1010: Send a second correction signal to the transmit link so that the second correction signal is modulated to the first frequency point, so that the second correction signal is transmitted to the coupling module through the antenna module;

[0097] Step S1020: Control the second switching switch to connect the coupling module and the second frequency conversion component, so that the receiving link receives the second correction signal of the first frequency point from the coupling module through the second switching switch;

[0098] Step S1030: Control the operation of the correction frequency conversion module so that the receiving link modulates the received second correction signal at the first frequency point;

[0099] Step S1040: Obtain the second correction signal received from the receiving link from the analog-to-digital conversion module to perform radio frequency signal correction.

[0100] In this embodiment, when radio frequency signal correction is required, the second correction signal is transmitted from the logic module to the transmit link and modulated to the first frequency point by the transmit link. The second correction signal then passes through the antenna module, the coupling module, and the second switching switch to reach the receive link. At this time, the control correction frequency conversion module is activated. The second correction signal is then modulated by the correction frequency conversion module, the down-conversion module, and the analog-to-digital conversion module and transmitted to the logic module to perform radio frequency signal correction, thereby realizing downlink antenna correction.

[0101] Applied to Figure 5 The control method of the communication equipment in this embodiment is basically the same as the process in this embodiment, except for the following two points: First, in step S1020, the second switching switch is connected to the coupling module and the analog-to-digital conversion module, instead of connecting the coupling module and the second frequency converter; Second, in step S1040, the second correction signal is obtained from the second frequency converter, instead of obtaining the second correction signal from the analog-to-digital conversion module.

[0102] like Figure 11 As shown, Figure 11 This is a flowchart of a control method for a communication device according to another embodiment of the present invention. This control method can be applied to... Figure 6 The communication device in the illustrated embodiment includes, but is not limited to, the following steps in its control method:

[0103] Step S1110: Send the first correction signal to the transmission link;

[0104] Step S1120: Control the first correction frequency conversion module to work so that the first correction signal is modulated to the second frequency point by the transmission link;

[0105] Step S1130: Control the first switching switch to connect the first frequency conversion component and the third switching switch, and control the third switching switch to connect the first switching switch and the coupling module, so that the first correction signal is transmitted to the antenna module through the first switching switch, the third switching switch and the coupling module;

[0106] Step S1140: Obtain the first correction signal of the second frequency point received from the antenna module by the receiving link to perform radio frequency signal correction.

[0107] This embodiment and Figure 9The control method is similar, except that there is an additional control over the third switching switch. The other functions and effects are the same, and will not be described in detail here.

[0108] In addition, if Figure 6 If the first frequency converter component is located at the front end of the digital-to-analog converter module, then in step S1130, the control of the first switching switch connects the digital-to-analog converter module and the third switching switch, rather than connecting the first frequency converter component and the third switching switch.

[0109] like Figure 12 As shown, Figure 12 This is a flowchart of a control method for a communication device according to another embodiment of the present invention. This control method can be applied to... Figure 6 The communication device in the illustrated embodiment includes, but is not limited to, the following steps in its control method:

[0110] Step S1210: Send a second correction signal to the transmit link so that the second correction signal is modulated to the first frequency point;

[0111] Step S1220: Control the first switching switch to connect the first frequency conversion component and the antenna module, so that the second correction signal is transmitted to the coupling module through the first switching switch and the antenna module;

[0112] Step S1230: Control the third switching switch to connect the coupling module and the second switching switch, and control the second switching switch to connect the third switching switch and the second frequency converter, so that the receiving link receives the second correction signal of the first frequency point from the coupling module through the second switching switch and the third switching switch;

[0113] Step S1240: Control the second correction frequency conversion module to work so that the receiving link modulates the received second correction signal at the first frequency point and transmits it to the logic module;

[0114] Step S1250: Obtain the second correction signal received by the receiving link to perform radio frequency signal correction.

[0115] This embodiment and Figure 10 The control method is similar, except that there is an additional control over the third switching switch. The other functions and effects are the same, and will not be described in detail here.

[0116] In addition, if Figure 6 If the first frequency converter component is located at the front end of the digital-to-analog converter module, then in step S1220, the control of the first switching switch connects the digital-to-analog converter module and the antenna module, rather than connecting the first frequency converter component and the antenna module; if Figure 6If the second frequency converter component is located at the rear end of the analog-to-digital converter module, then in step S1230, the second switching switch is connected to the third switching switch and the analog-to-digital converter module, rather than connecting the third switching switch and the second frequency converter component.

[0117] Reference Figure 13 As shown, a specific hardware circuit embodiment of the communication device according to the above embodiments of the present invention is given, based on Figure 13 The hardware circuitry and radio frequency signal correction process are as follows:

[0118] For example, the normal operating frequency range of the transmission link of the communication device is 1805MHz-1880MHz, and the normal operating frequency range of the reception link is 1710MHz-1785MHz.

[0119] 1. During uplink correction: The first correction signal is transmitted from the logic module to the multiplexed transmit link via the dual-speed motor integrated protection device (JESD). At this time, the digital signal frequency before reaching the numerically controlled oscillator (NCO) is 0MHz, and the NCO function is activated. The NCO's frequency shift capability is (1785+1710) / 2-(1880+1805) / 2=-95MHz. After passing through the NCO, the intermediate frequency signal becomes -95MHz. After passing through the DAC, and then through the external fast LO upconversion module, where LO=(1880+1805) / 2=1842.5MHz, the output analog signal frequency is 1747.5MHz, which is equal to the uplink center frequency. At this time, switch sw1 on the transmit link connects the transmit link and the coupling module, and the first correction signal is distributed to each receiving channel via the coupling module.

[0120] 2. Downlink Correction: The second correction signal is transmitted from the logic module to the normal transmit link via the dual-speed motor integrated protector (JESD). At this time, the NCO on the transmit link is in bypass mode. After frequency conversion on the transmit link, the output signal is 1842.5MHz. The second correction signal reaches the coupling module from the antenna module and is finally combined. After passing through switches sw3 and sw2, it reaches the receive link. After passing through the ADC device, the intermediate frequency signal should be 95MHz. Then, after passing through the NCO, the intermediate frequency signal becomes 0MHz before being transmitted to the JESD.

[0121] Reference Figure 14 As shown, another specific hardware circuit embodiment of the communication device of the above embodiments of the present invention is given, and... Figure 13Compared to the illustrated embodiment, this embodiment differs in that it does not use an NCO module, but instead uses an external fast LO up / down frequency converter module to simulate up / down auxiliary frequency conversion. Specifically:

[0122] 1. During uplink correction: The logic module sends a 0MHz digital signal, which is upconverted by the DAC itself and outputs an analog signal of (1880+1805) / 2=1842.5MHz. After being downconverted by the auxiliary LO to -95MHz, the first correction signal of 1747.5MHz is output.

[0123] 2. During downlink correction, the second correction signal is transmitted from the logic module to the normal transmit link via the dual-speed motor integrated protector (JESD). At this time, the NCO on the transmit link is in bypass mode. After up-conversion on the transmit link, the output signal is 1842.5MHz. The second correction signal travels from the antenna module to the coupling module, where it is finally combined and passes through switches sw3 and sw2 before reaching the receive link. After down-conversion by -95MHz via the auxiliary LO, a second correction signal of 1747.5MHz is obtained, which is then successfully received by the ADC operating in the uplink band.
