Abstract
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 transceiver and its control method, and a computer-readable storage medium. Background Technology
[0002] In related technologies, a typical architecture for a 5G millimeter-wave multi-channel transceiver is as follows: Figure 1 As shown, a local oscillator signal is configured through a phase-locked loop chip. This local oscillator signal is then used as the local oscillator signal for the frequency conversion modules of multiple transceiver channels after passing through a power divider. Therefore, when the intermediate frequency signal of each transceiver channel is fixed and consistent, the frequency of the radio frequency signal of multiple transceiver channels can be kept consistent. If it is necessary to change the frequency of the radio frequency signal, it can be achieved by configuring local oscillator signals of different frequencies or by changing the frequency of the intermediate frequency signal.
[0003] However, with a fixed intermediate frequency (IF) signal bandwidth, the above methods cannot broaden the RF signal bandwidth. If it is necessary to broaden the RF signal bandwidth, the IF signal bandwidth needs to be broadened. Broadening the IF signal bandwidth requires further increasing the sampling rate of the digital-to-analog converter (DAC) and analog-to-digital converter (ADC). However, DACs with higher sampling rates are more expensive, which is not conducive to cost reduction. Moreover, a wider IF signal requires higher image frequency suppression requirements when performing DAC or ADC processing. In addition, a wider IF signal requires more software resources when performing digital up-conversion and digital down-conversion processing. Summary of the Invention
[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.
[0005] This invention provides a transceiver and its control method, as well as a computer-readable storage medium, which can broaden the bandwidth of radio frequency signals without changing the bandwidth of intermediate frequency signals.

The second type of signal transmission link includes a second type of mixer connected to the auxiliary local oscillator module. The control processing module is connected to both the primary and auxiliary local oscillator modules and is configured to operate at different frequencies based on the instantaneous bandwidth (IBW). Without changing the intermediate frequency bandwidth of the transceiver, by switching the operating mode and allocating power to the local oscillator module, the sampling rate requirements for the digital-to-analog converter (DAC) and analog-to-digital converter (ADC) are reduced. Without using high-sampling-frequency ADCs and ADCs, the transceiver's air interface bandwidth is adjusted according to the instantaneous bandwidth (IBW) of different frequency band signals, thereby enabling the transmission and reception of 5G millimeter-wave signals in different frequency bands.

Detailed Implementation
[0027] 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.
[0028] 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.
[0029] This invention provides a transceiver and its control method, as well as a computer-readable storage medium. The transceiver includes a primary local oscillator module 1010, an auxiliary local oscillator module 1020, a first type of signal transmission link 1030, a second type of signal transmission link 1040, and a control processing module 1090.

Without changing the intermediate frequency bandwidth, by controlling the operating frequency of the local oscillator module, the sampling rate requirements of the digital-to-analog converter and the analog-to-digital converter are reduced, the suppression requirements for the image frequency during digital-to-analog conversion or analog-to-digital conversion are reduced, and the software resources required for the intermediate frequency signal to undergo digital up-conversion and digital down-conversion are reduced, thereby enabling the transmission and reception of 5G millimeter-wave signals in different frequency bands.
[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0031] like Figure 2 As shown, Figure 2 This is a schematic diagram of the transceiver provided in one embodiment of the present invention. Figure 2 In the example, the transceiver includes a primary local oscillator module 1010, an auxiliary local oscillator module 1020, a first type of signal transmission link 1030, a second type of signal transmission link 1040, and a control processing module 1090. The first type of signal transmission link 1030 is equipped with a first type of mixer 1031; the second type of signal transmission link 1040 is equipped with a second type of mixer 1041. The first type of mixer 1031 is connected to the primary local oscillator module 1010, and the second type of mixer 1041 is connected to the auxiliary local oscillator module 1020. The control processing module 1090 is connected to both the primary local oscillator module 1010 and the auxiliary local oscillator module 1020.
[0032] In some embodiments, the primary local oscillator module 1010 includes at least one primary local oscillator, which is used to provide local oscillator signals for the first type of signal transmission link 1030 and the second type of signal transmission link 1040 when the transceiver is transmitting uplink and downlink signals.
[0033] In some embodiments, the auxiliary local oscillator module 1020 includes at least one auxiliary local oscillator, which is used to provide a local oscillator signal to a portion of the second type of signal transmission link 1040 when dual local oscillators are enabled.
[0034] In some embodiments, the control processing module 1090 includes a field-programmable gate array (FPGA) chip.
[0035] In some embodiments, the transceiver further includes a baseband unit (BBU), which is used to implement functions including channel encoding and decoding, modulation and demodulation of baseband signals, protocol processing, etc., and provides interface functions with upper-layer network elements.
[0036] In some embodiments, the transceiver is also connected to an antenna array 1110, which includes antenna arrays required for various cell structures, such as omnidirectional antenna arrays, sector antenna arrays, star antenna arrays, and chain antenna arrays. It is worth noting that the antenna array 1110 in this embodiment can be an existing antenna array used for transmitting and receiving 2G, 3G, 4G, or 5G Sub-6GHz signals, which is a conventional design in the art and will not be described further here.
[0037] In some embodiments, the field-programmable gate array (FPGA) chip in the transceiver determines whether the instantaneous bandwidth (IBW) requirement is greater than the intermediate frequency (IF) bandwidth. If the instantaneous bandwidth (IBW) requirement is less than or equal to the IF bandwidth, the first switch is switched to the first fixed contact of the first switch, so that the main local oscillator of the transceiver provides the local oscillator signal within the link, and the frequency of the main local oscillator is set so that different channels of the transceiver are at the same frequency. If the instantaneous bandwidth (IBW) requirement is greater than the IF bandwidth, the first switch is switched to the second fixed contact of the first switch, and the main local oscillator and the auxiliary local oscillator are used to provide the local oscillator signal during uplink and downlink frequency conversion within the link to match the instantaneous bandwidth (IBW). The FPGA chip sets the operating frequencies of the main local oscillator and the auxiliary local oscillator according to the instantaneous bandwidth (IBW). Part of the local oscillator signal in the transceiver is provided by the main local oscillator, and the other part is provided by the auxiliary local oscillator. Using the dual local oscillator operating mode of the transceiver can adjust the IF bandwidth of the transceiver, thereby improving the transceiver's IF bandwidth processing capability and increasing the IF bandwidth range of the transceiver.
[0038] In some embodiments, the transceiver further includes at least one first power divider 1050 and at least one second power divider 1130, a first type mixer 1031 is connected to a main local oscillator module 1010 through the first power divider 1050, and a second type mixer 1041 is connected to an auxiliary local oscillator module 1020 through the second power divider 1130.
[0039] In some embodiments, the first power divider 1050 is used to distribute the power of the main local oscillator module 1010, and the first power divider 1050 uses the main local oscillator module 1010 and the first type of mixer 1031 respectively.
[0040] In some embodiments, the second power divider 1130 is used to distribute the power of the auxiliary local oscillator module 1020, and the second power divider 1130 assists the local oscillator module 1020 and the second type of mixer 1041 respectively.
[0041] In some embodiments, the transceiver further includes at least one first switch module 1070. The first switch module 1070 includes a first switch control terminal, a first switch moving contact, a first switch first fixed contact, and a first switch second fixed contact. The first switch moving contact is connected to a second power divider 1130, the first switch first fixed contact is connected to a first power divider 1050, the first switch second fixed contact is connected to an auxiliary local oscillator module 1020, and the first switch control terminal is connected to a control processing module 1090.
[0042] In one embodiment, when the instantaneous frequency IBW is less than the intermediate frequency bandwidth, the control processing module 1090 can control the first switch control terminal to connect the first switch module 1070 to the first fixed contact of the first switch. This means that only the primary local oscillator is used to provide the local oscillator signal during uplink and downlink frequency conversion of the channel, while the auxiliary local oscillator is turned off to reduce the transceiver's power consumption. The frequency of the primary local oscillator module 1010 is also adjusted so that the local oscillator signal of the transceiver is provided entirely by the primary local oscillator module 1010, and different channels of the transceiver are at the same frequency to complete the transmission and reception of millimeter-wave signals, thereby achieving compatibility with transceivers in related technologies.
[0043] In one embodiment, when the instantaneous frequency IBW is greater than the intermediate frequency bandwidth, the control processing module 1090 can control the first switch control terminal to connect the first switch module 1070 to the second fixed contact of the first switch. This means that both the primary local oscillator module 1010 and the auxiliary local oscillator module 1020 are used simultaneously to provide the local oscillator signal during uplink and downlink frequency conversion, thereby obtaining a larger intermediate frequency bandwidth. The frequencies of the primary local oscillator module 1010 and the auxiliary local oscillator module 1020 are adjusted so that the local oscillator signal in the transceiver is provided by the primary local oscillator module 1010 and the auxiliary local oscillator module 1020, respectively, to complete the transmission and reception of millimeter-wave signals. By using dual local oscillator modules, the intermediate frequency bandwidth of the transceiver can be adjusted, thereby increasing the intermediate frequency bandwidth of the transceiver without using analog-to-digital converters and digital-to-analog converters with higher sampling rates, and thus improving the signal bandwidth of the transceiver.
[0044] In some embodiments, the first switch module 1070 may be a single-pole double-throw switch. Using a single-pole double-throw switch can realize the direct switching between the first fixed contact and the second fixed contact of the first switch, that is, the switching between the first power divider 1050 and the second power divider 1130, thereby realizing the switching between using only the main local oscillator module 1010 and using both the main local oscillator module 1010 and the auxiliary local oscillator module 1020, and improving the space utilization of the product.
[0045] In some embodiments, the transceiver further includes a second switch module 1080, a third power divider 1150, and a calibration link for calibrating the transmitted signal. The calibration link is coupled to a first type of signal transmission link 1030 and a second type of signal transmission link 1040 via the third power divider 1150. The calibration link includes a calibration mixer, which is connected to a main local oscillator module 1010 and an auxiliary local oscillator module 1020 via the second switch module 1080.
[0046] In some embodiments, the transceiver also includes a single-LO transmit calibration mode. In this mode, the second switch module 1080 adjusts the calibration link by adjusting the third power divider 1150, and changes the transceiver's operating mode to single-LO transmit calibration mode. The transceiver simultaneously transmits multiple digital-to-analog signals containing calibration sequences and converts the transmitted signals into millimeter-wave signals. The calibration mixer within the calibration link couples the multiple millimeter-wave signals into a single millimeter-wave signal. The control processing module 1090 analyzes the coupled millimeter-wave signal and forms an intermediate frequency (IF) signal within the first type of signal transmission link 1030. The IF signal within the first type of signal transmission link 1030 is sampled from analog to digital, and the sampled signal is analyzed. Based on the analysis results, the delay and gain within the first type of signal transmission link 1030 are adjusted to compensate for the signal amplitude and phase within the link. Using the single-LO transmit calibration mode can calibrate the transmitted signal of the transceiver when using a single LO for millimeter-wave signal transmission and reception, improving the signal recognition rate and reducing the requirements for signal demodulation.
[0047] In some embodiments, the transceiver also includes a single-LO receive calibration mode. In this mode, the second switch module 1080 adjusts the calibration link by adjusting the fifth power divider, and changes the transceiver's operating mode to single-LO receive calibration mode. The transceiver transmits a digital-to-analog signal containing a calibration sequence, and converts the received signal into a millimeter-wave signal via the fourth power divider 1060. The calibration mixer within the calibration link couples multiple millimeter-wave signals into a single millimeter-wave signal. The control processing module 1090 analyzes the coupled millimeter-wave signal and forms an intermediate frequency (IF) signal within the first type of signal transmission link 1030. The IF signal within the first type of signal transmission link 1030 is sampled from analog to digital, and the sampled signal is analyzed. Based on the analysis results, the delay and gain within the first type of signal transmission link 1030 are adjusted to compensate for the signal amplitude and phase within the link. Using the single-LO receive calibration mode allows the transceiver to calibrate the received signal when using single-LO signal transmission, improving the transceiver's recognition rate of the received signal.
[0048] In some embodiments, the transceiver further includes a fourth power divider 1060, and the second switch module 1080 includes a second switch control terminal, a second switch moving contact, a second switch first fixed contact, and a second switch second fixed contact. The second switch moving contact is connected to a calibration mixer, the second switch first fixed contact is connected to a first power divider 1050, the second switch second fixed contact is connected to an auxiliary local oscillator module 1020 through the fourth power divider 1060, and the second switch control terminal is connected to a control processing module 1090.
[0049] In some embodiments, the transceiver also includes a dual-LO transmit calibration mode. In the single-LO transmit / receive calibration mode, the second switch module 1080 adjusts the calibration link and changes the transceiver's operating mode to dual-LO transmit calibration mode. The transceiver simultaneously transmits multiple digital-to-analog signals containing calibration sequences. The transmitted signals are converted into millimeter-wave signals by the fourth power divider 1060. The calibration mixer within the calibration link couples the multiple millimeter-wave signals into a single millimeter-wave signal. The control processing module 1090 analyzes the coupled millimeter-wave signal and forms an intermediate frequency (IF) signal within the first type of signal transmission link 1030. The IF signal within the first type of signal transmission link 1030 is sampled from analog to digital, and the sampled signal is analyzed. Based on the analysis results, the delay and gain within the first type of signal transmission link 1030 are adjusted to compensate for the signal amplitude and phase within the link. Using the dual-LO transmit calibration mode can calibrate the transmit signals of the two LOs within the transceiver, improving the transmission accuracy of the transceiver in dual-LO transmit mode.
[0050] In some embodiments, the second switch module 1080 can be a single-pole double-throw switch. Using a single-pole double-throw switch can realize the direct switching between the first fixed contact of the second switch and the second fixed contact of the second switch, that is, the switching between the first power divider 1050 and the fourth power divider 1060, thereby realizing the switching between using only the main local oscillator module 1010 and using both the main local oscillator module 1010 and the auxiliary local oscillator module 1020, and saving internal space of the product.
[0051] In some embodiments, the transceiver further includes a third switch module and a fourth switch module. Each first type mixer 1031 is connected to each first power divider 1050 and each second power divider 1130 through the third switch module, and each second type mixer 1041 is connected to each first power divider 1050 and each second power divider 1130 through the fourth switch module.
[0052] In some embodiments, the transceiver further includes a fifth switch module, a fifth power divider, and a calibration link for calibrating the transmitted signal. The calibration link is coupled to a first type of signal transmission link 1030 and a second type of signal transmission link 1040 via the fifth power divider. The calibration link includes a calibration mixer, which is connected to a main local oscillator module 1010 and an auxiliary local oscillator module 1020 via the fifth switch module.
[0053] In some embodiments, the transceiver also includes a dual-LO receive calibration mode. In the dual-LO receive calibration mode, the fifth switch module adjusts the calibration link by adjusting the fifth power divider and changes the transceiver's operating mode to dual-LO receive calibration mode. The transceiver transmits a digital-to-analog signal containing a calibration sequence and converts the transmitted signal into a millimeter-wave signal. The calibration mixer in the calibration link couples multiple millimeter-wave signals into a millimeter-wave signal with half the number of links. The control processing module 1090 analyzes the coupled millimeter-wave signal with half the number of links and forms an intermediate frequency (IF) signal in the first type of signal transmission link 1030. The IF signal in the first type of signal transmission link 1030 is sampled from analog to digital and analyzed. Based on the analysis results, the time delay and gain in the first type of signal transmission link 1030 are adjusted to compensate for the signal amplitude and phase within the link. Using the dual-LO receive calibration mode can improve the accuracy of the transceiver receiving and identifying signals in the dual-LO receive mode.
[0054] In some embodiments, the transceiver further includes a coupling module 1140, which includes at least one coupler 1141. The coupling module 1140 is used to couple the signals generated by the third power divider 1150 and the first type mixer 1031, and is also used to couple the signals generated by the third power divider 1150 and the second type mixer 1041.
[0055] In some embodiments, the transceiver further includes at least one sixth power divider and at least one seventh power divider. The main local oscillator module 1010 is connected to the first power divider 1050 and the fifth switch module through the sixth power divider, and the auxiliary local oscillator module 1020 is connected to the second power divider 1130 and the fifth switch module through the seventh power divider.
[0056] In some embodiments, the transceiver further includes a multi-local oscillator operating mode. For example, the transceiver includes M local oscillators, and a total of m local oscillators are enabled, where m <= M. IF_BW is the intermediate frequency bandwidth of a single local oscillator in the multi-local oscillator operating mode of the transceiver. When the transceiver is in the multi-local oscillator operating mode, the control processing module 1090 determines whether the instantaneous bandwidth IBW requirement is less than the intermediate frequency bandwidth of a single local oscillator. If the instantaneous bandwidth IBW requirement is less than or equal to the intermediate frequency bandwidth of a single local oscillator, a single local oscillator is enabled, and one local oscillator of the transceiver is enabled to provide the local oscillator signal within the link, and the frequency of this local oscillator is set so that different channels of the transceiver are at the same frequency. Determine whether IBW satisfies m * IF_BW < IBW. If m * IF_BW < IBW. Determine whether IBW satisfies (m - 1) * IF_BW < IBW <= m * IF_BW. If the instantaneous bandwidth IBW requirement is greater than the intermediate frequency bandwidth of a single local oscillator, switch the first switch to the first and second fixed contacts of the first switch, and use m local oscillators to provide the local oscillator signals for up / down conversion within the link to match the instantaneous bandwidth IBW. The control processing module 1090 respectively sets the operating frequencies of the primary local oscillator and the auxiliary local oscillator according to the instantaneous bandwidth IBW. Some of the local oscillator signals in the transceiver are provided by the primary local oscillator, and the other part is provided by the auxiliary local oscillator. Using the multi-local oscillator operating mode of the transceiver can further adjust the intermediate frequency bandwidth of the transceiver to improve the processing ability of the transceiver for the intermediate frequency bandwidth, achieving full coverage of the millimeter-wave intermediate frequency bandwidth that the transceiver can process.
[0057] In some embodiments, when the transceiver enables the multi-local oscillator operating mode, the first type of signal transmission link 1030 is the same as the second type of signal transmission line.
[0058] In some embodiments, in the single-local oscillator operating mode of the transceiver, the output bandwidth of the transceiver is the intermediate frequency processing bandwidth, and the center frequency depends on the local oscillator frequency. When the transceiver is in the dual-local oscillator mode, the output spectrum of the transceiver is adjustable. By adjusting the frequency difference between the primary local oscillator and the auxiliary local oscillator, the intermediate frequency bandwidth of the transceiver can be adjusted, thereby realizing the adjustment of the 5G millimeter-wave transceiver frequency band of the transceiver.
[0059] As Figure 3 shown, Figure 3 is a flowchart of a control method for a transceiver provided by an embodiment of the present invention. The control method includes but is not limited to step S100: obtaining the instantaneous bandwidth IBW and S200: configuring the primary local oscillator module and the auxiliary local oscillator module according to the instantaneous bandwidth IBW.
[0060] Configure the primary local oscillator module 1010 and the auxiliary local oscillator module 1020 to different operating frequencies.
[0061] Step S100: Obtain the instantaneous bandwidth IBW.
[0062] In some embodiments, acquiring the instantaneous bandwidth IBW allows the transceiver to adjust the local oscillator mode according to different instantaneous bandwidths IBW.
[0063] Step S200: Configure the primary local oscillator module and the auxiliary local oscillator module according to the instantaneous bandwidth IBW.
[0064] In some embodiments, the primary local oscillator module 1010 and the auxiliary local oscillator module 1020 are configured to operate at different frequencies according to the instantaneous bandwidth IBW.
[0065] like Figure 4 As shown, Figure 4 This is a flowchart of a control method for a transceiver provided in another embodiment of the present invention. The control method includes, but is not limited to, the following steps: S210: Determining whether the instantaneous bandwidth IBW is greater than the bandwidth of the intermediate frequency signal; S220: Applying a multi-local oscillator operating mode; S221: Enabling the second type of signal transmission link; S222: Configuring the primary local oscillator module and the auxiliary local oscillator module; S230: Applying a single local oscillator operating mode; S231: Disabling the auxiliary local oscillator module; S232: Switching the first switch module; S240: Configuration complete.
[0066] S210: Determine whether the instantaneous bandwidth IBW is greater than the bandwidth of the intermediate frequency signal.
[0067] In some embodiments, the instantaneous bandwidth IBW required by the transceiver is obtained, and it is determined whether the instantaneous bandwidth IBW is greater than the bandwidth of the intermediate frequency signal. The determination of the instantaneous bandwidth IBW can realize the switching of the transceiver mode. The transceiver's working mode includes using the main local oscillator module and using the dual local oscillator module.
[0068] S220: Uses multi-local oscillator operating mode.
[0069] In some embodiments, the dual local oscillator (DLO) operating mode is enabled when the instantaneous bandwidth IBW is greater than the bandwidth of the intermediate frequency (IF) signal. Using the dual LO operating mode allows the transceiver to obtain a larger bandwidth, enabling adjustment of the transceiver's operating frequency band when the instantaneous bandwidth IBW is greater than the IF signal. This allows the transceiver to increase its signal bandwidth without using high-sampling-rate digital-to-analog converters (DACs) and analog-to-digital converters (ADCs).
[0070] In some embodiments, when the instantaneous bandwidth IBW satisfies (m - 1)*IF_BW < IBW <= m*IF_BW, X master local oscillator modules 1010 and Y auxiliary local oscillator modules 1020 are enabled, and the X master local oscillator modules 1010 and the Y auxiliary local oscillator modules 1020 are configured with different operating frequencies. Here, IF_BW is the bandwidth of the intermediate-frequency signal, and m = X + Y. Among them, the master local oscillator and the auxiliary local oscillator in the master local oscillator module 1010 and the auxiliary local oscillator module 1020 can be configured as the same local oscillator. Enabling multiple master local oscillators and auxiliary local oscillators can further increase the air interface occupied bandwidth of the transceiver and achieve full coverage of the transceiver in the 5G frequency band.
[0071] S221: Enable the second type of signal transmission link.
[0072] In some embodiments, when applying the multi-local oscillator operating mode, it is necessary to enable the auxiliary local oscillator for signal link transmission.
[0073] S222: Configure the master local oscillator module and the auxiliary local oscillator module.
[0074] In some embodiments, configure the master local oscillator module 1010 and the auxiliary local oscillator module 1020, and adjust the frequencies of the master local oscillator and the auxiliary local oscillator to adjust the bandwidth of the transceiver, thereby achieving frequency band adjustment of the transceiver.
[0075] S230: Apply the single-local oscillator operating mode.
