[0036] In this invention, by fusing the analysis of the time-domain power periodicity and frequency-domain paired frequency characteristics of the signal, a highly reliable automatic TDD / FDD discrimination mechanism can be constructed. Through establishing a precise "discrimination-instruction" mapping: TDD mode triggers time slot synchronous switching, while FDD mode activates a duplexer to achieve full-duplex operation. This enables a single repeater to automatically identify and be compatible with both TDD and FDD, the two mainstream duplex modes, improving the equipment's versatility and deployment flexibility, and reducing operators' equipment inventory and maintenance costs. Simultaneously, it possesses continuous monitoring and re-discrimination capabilities, automatically triggering a seamless switching process after network standard changes, ensuring service continuity. By achieving accurate tracking and efficient relaying of the main network signal by the repeater, it guarantees communication quality and user experience in the coverage area.

[0040] The method embodiment provided in Embodiment 1 of this application can be executed on a mobile terminal, computer terminal, or similar computing device. Figure 1 A hardware block diagram of a computer terminal (or mobile device) for implementing a configuration method for an antenna system is shown. Figure 1 As shown, computer terminal 10 (or mobile device) may include one or more ( Figure 1The processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions may also be included.

For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0041] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuits may be a single, independent processing module, or may be integrated, in whole or in part, into any other element within the computer terminal 10 (or mobile device). As involved in the embodiments of this application, the data processing circuits serve as a processor control mechanism (e.g., selection of a variable resistor termination path connected to an interface).

[0042] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the antenna system configuration method in this embodiment. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, thereby realizing the antenna system configuration method described above.

[0043] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the communication provider of the computer terminal 10. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet.

[0044] The display may be, for example, a touchscreen liquid crystal display (LCD) that allows the user to interact with the user interface of the computer terminal 10 (or mobile device).

[0045] Under the aforementioned operating environment, this application provides the following: Figure 2 The antenna system configuration method is shown. Figure 2 This is a flowchart of the antenna system configuration method according to Embodiment 1 of this application, as follows: Figure 2 As shown, the method includes the following steps:

[0046] Step S201: The control signal processing unit extracts data from the received wireless signal to obtain time-domain data and frequency-domain data within the current time window.

[0047] Optionally, the method is applied to an optical fiber repeater, which includes at least a near-end unit and a far-end unit. The far-end unit includes at least a signal processing unit and an antenna system. The antenna system includes at least one duplex antenna for receiving uplink signals and transmitting downlink signals.

[0048] In this embodiment of the invention, the signal processing unit can be controlled to continuously monitor the wireless signal received by the radio frequency front end and divide the signal into multiple time windows of equal length. Within each time window, the signal processing unit extracts the time-domain and frequency-domain features of the signal (time-domain data and frequency-domain data). For example, for a time-domain signal, the signal processing unit can calculate the short-term average power, power variation variance, and detect periodic transmit / receive time slot characteristics; for a frequency-domain signal, it can detect features such as peak frequency and frequency spacing in the spectrum for subsequent standard identification and antenna configuration.

[0049] Figure 3 This is a schematic diagram of an optional fiber optic repeater system according to an embodiment of this application, such as... Figure 3As shown, a fiber optic repeater system includes: a signal source, a radio frequency access unit, an SMSC (Short Message Service Center) or switching center, a network management center, optical fibers, radio frequency cables, and a remote unit. The signal source (i.e., the base station) provides the wireless signal. The radio frequency access unit, located near the repeater, receives the base station's wireless signal and converts it into an optical signal, transmitting it to the remote unit via optical fiber or radio frequency cable. The remote unit is responsible for the final amplification and transmission of the signal to the user. The radio frequency cable can also be used to connect the antenna system. At the base station, control information and status data can be transmitted to the radio frequency access unit via wired coupling (such as Ethernet). Based on a monitoring and reporting mechanism, this data can be sent to the SMSC or switching center via wired or wireless means. The gateway monitoring platform collects monitoring information from the SMSC or switching center, integrates it, and forwards it to the network management center. The network management center monitors the health status and performance indicators of the entire network, issues network configuration commands, and performs network planning and optimization.

[0050] Step S202: Based on time-domain data and frequency-domain data, determine the target operating mode of the antenna system.

[0051] In this embodiment of the invention, the target operating mode of the antenna system can be determined based on time-domain data and frequency-domain data. If the signal shows periodic power fluctuations in the time domain and there are no obvious paired frequency intervals in the frequency domain, the target operating mode of the antenna system can be determined as TDD mode (i.e., frequency division duplex mode). Conversely, if stable paired frequency points are detected in the frequency domain data and the signal strength is relatively stable in the time domain data, the target operating mode of the antenna system can be determined as FDD mode (i.e., frequency division duplex mode).

[0052] Step S203: Configure the antenna system based on the target operating mode and monitor the operating mode for the next time window length, wherein each time window length is the same and the start point of the next time window length is later than the end point of the current time window length.

[0053] In this embodiment of the invention, based on the target operating mode, control commands can be generated to configure the antenna system and adjust the antenna's operating state. For example, in TDD mode, the antenna receives signals in the downlink time slot and transmits signals in the uplink time slot to avoid self-interference; in FDD mode, a duplexer is enabled, allowing the antenna to transmit and receive simultaneously on different frequency bands. Simultaneously, the characteristic changes of the signal within the next time window can be continuously monitored to determine the operating mode of the next time window. Each time window has the same length, and the start point of the next time window is later than the end point of the current time window.

[0054] Step S204: If the operating mode changes in the next time window, the antenna system is reconfigured.

[0055] In this embodiment of the invention, if the working mode of the next time window length is different from the target working mode of the current target time window length, the antenna system can be reconfigured. For example, the original TDD mode suddenly changes to FDD mode, or vice versa, the antenna system needs to be reconfigured according to the newly determined working mode to adapt to the change of network standard.

[0056] Figure 4 This is a flowchart of an optional configuration antenna system according to an embodiment of this application, such as... Figure 4 As shown, the system first continuously monitors the wireless signal and extracts its features (time domain and frequency domain features), including signal power and spectrum. Then, time domain and frequency domain feature analysis is performed to obtain time domain and frequency domain data (e.g., signal power variance, frequency differences, etc.). Based on the time domain and frequency domain data, the target operating mode of the antenna system (e.g., TDD or FDD mode) can be determined. If the target operating mode is TDD, self-interference can be avoided through time slot synchronization, and the antenna's transmit / receive switching can be controlled by a high-speed RF switch to control the time slot synchronization between the antenna and the base station, thus avoiding self-interference. If the target operating mode is FDD, the duplexer of the antenna system is activated, and the wireless signal can be continuously tracked. If the wireless signal is continuously tracked (i.e., continuously monitored), the time and frequency domain analysis of the signal within the next time window can be performed to monitor the operating mode within the next time window.

[0057] In summary, the signal processing unit can continuously monitor the received wireless signal and extract the power time slot variation pattern and frequency distribution characteristics of the wireless signal within the current time window. Based on these characteristics, it can intelligently determine the target operating mode of the signal (i.e., TDD or FDD mode). Based on the determined target operating mode, it can dynamically configure the antenna system and continuously monitor the signal. When the network standard changes, it can automatically reconfigure the antenna system, achieving smooth switching under dynamic adjustment of network parameters. This solves the technical problem of not being able to automatically configure different duplex modes of the antenna system in related technologies.

[0058] To accurately determine time-domain and frequency-domain data, in the antenna system configuration method provided in Embodiment 1 of this application, the wireless signal is sampled within the current time window length to obtain multiple sampled signals, wherein each sampled signal corresponds to a signal power; all signal powers within the current time window length are determined; a signal power sequence is constructed based on all signal powers, and time-domain data is determined based on the signal power sequence; Fourier transform is performed on all sampled signals within the current time window length to obtain a spectrum, and frequency-domain data is determined based on the spectrum.

[0059] In this embodiment of the invention, within the current time window, wireless signals can be sampled at a preset sampling frequency to obtain multiple sampled signals and the signal power of each sampled signal. The sampling frequency must satisfy the Nyquist sampling theorem, meaning the sampling frequency must be at least twice the highest frequency of the signal. All signal powers within the current time window are determined, and a signal power sequence can be constructed based on all signal powers. For example, if the time window length is 1 ms, the collected signal strength values ​​(i.e., signal power) can be arranged in chronological order to generate a signal power sequence. Based on the signal power sequence, time-domain data (e.g., short-time average power, power variance, etc.) can be determined, and a Fourier transform is performed on all sampled signals within the current time window to obtain a spectrum. Based on the spectrum, frequency-domain data (e.g., the difference between the frequency values ​​of two frequency points) can be determined.

[0060] In order to accurately determine the time-domain data, in the antenna system configuration method provided in Embodiment 1 of this application, the sliding window length is determined, and all sampled signals within each sliding window length are determined; based on the signal power sequence, the average signal power within each sliding window length is calculated; for each sliding window length, based on the average signal power, the signal power variance is calculated, and the signal power variance is represented as time-domain data.

[0061] In this embodiment of the invention, it is necessary to determine a sliding window length. The corresponding time slot length (e.g., 1ms) allows us to determine all sampled signals within each sliding window length. Based on the signal power sequence, we can calculate the average signal power (i.e., the signal average power of all sampled signals within each sliding window length) ,in, This represents the last sampling point within the length of the sliding window, where k represents the k sampling points preceding the last sampling point. For example... It is 5. If it is 5, then The power is calculated from five consecutive signal power samples, P(5), P(4), P(3), P(2), and P(1), representing the average power within the five sample groups centered on the fifth sample.

[0062] For each sliding window length, the signal power variance (i.e., ...) can be calculated based on the average signal power. Where n is the nth sampling point within the length of the sliding window, n=1,…,N, and N is the total number of sampling points within the length of the sliding window. This represents the signal power of the nth sampling point within the length of the sliding window, and the variance of this signal power can be characterized as time-domain data.

[0063] The spectrum data includes at least: multiple frequency points, the frequency value of each frequency point, and the amplitude of each frequency point. In order to accurately determine the frequency domain data, in the antenna system configuration method provided in Embodiment 1 of this application, the mean of all amplitudes is calculated, and the derivative of each amplitude at the corresponding frequency point is calculated. For each amplitude, if the amplitude is greater than the target amplitude threshold and the derivative is equal to zero, the frequency value of the frequency point corresponding to the amplitude is added to the frequency point set. The target amplitude threshold is determined based on the preset amplitude threshold and the mean. The difference between any two frequency values ​​in the frequency point set is calculated, and the difference is represented as frequency domain data.

[0064] In this embodiment of the invention, the data of each spectrum graph includes at least multiple frequency points, the frequency value of each frequency point, and the amplitude of each frequency point. It can calculate the mean of all amplitudes in each spectrum. And calculate the derivative of each amplitude at the corresponding frequency point, and can be based on a preset amplitude threshold ( The value can be set between 2 and 3) and the mean, to calculate the target amplitude threshold (i.e. For each amplitude, when the amplitude is greater than the target amplitude threshold (i.e. And the derivative is equal to zero (i.e. In the case of ), the frequency point corresponding to the amplitude. Add the frequency value to the frequency point set And calculate the difference between any two frequency values ​​in the set of frequency points (i.e., Thus, the difference between any two frequency values ​​can be obtained, and the difference can be represented as frequency domain data.

[0065] To accurately determine the target operating mode as frequency division duplex mode, in the antenna system configuration method provided in Embodiment 1 of this application, when the signal power variance is greater than a preset variance threshold and the signal power exhibits periodicity within the current time window, the target operating mode is determined to be time division duplex mode, wherein the periodicity is obtained by detecting an autocorrelation function; or, when any difference is detected to be within a preset frequency range, two frequency points corresponding to the difference are determined; the amplitudes of the two frequency points within a preset duration are monitored; when the amplitudes are detected to be within a preset range, the target operating mode is determined to be frequency division duplex mode.

[0066] Optionally, within each sliding window, the autocorrelation function (i.e. ,in, The autocorrelation factor (e.g., 5ms or 10ms, which can be set manually) detects whether the signal exhibits periodic changes within multiple sliding windows; the autocorrelation function... It can detect the signal at the current time point n and After the time unit The similarity between points in time, if the signal is periodic, then... When it is an integer multiple of the signal period, It will display a high value (i.e., peak value), at which point it can be determined that the signal power has periodicity within the current time window.

[0067] In this embodiment of the invention, when the signal power variance is greater than a preset variance threshold (i.e.) If the signal power exhibits periodicity within the current time window, the target operating mode will be determined as time-division duplex mode (e.g., ...). ).

[0068] When any difference is detected to be within the preset frequency range (i.e.) In the case of this, the two frequency points corresponding to the difference are determined. The preset frequency range can be set to a common FDD duplex interval range (e.g., 45MHz-400MHz), and the amplitude of the two frequency points within a preset time period can be monitored. If the amplitude is detected to be within the preset range (which can be set by the user), the target operating mode can be determined as frequency division duplex mode (i.e., frequency division duplex mode). ).

[0069] Figure 5 This is a flowchart of an optional discrimination working mode according to an embodiment of this application, such as... Figure 5As shown, firstly, time-domain and frequency-domain features are extracted to determine the values ​​of C_TDD and C_FDD. If C_TDD=1 (i.e., the signal is detected to exhibit periodic high-power downlink time slots and low-power uplink time slots on a single frequency band), it is determined to be in TDD mode. In this case, the antenna system can be controlled to synchronize with the base station signal time slots. In the downlink time slot, the antenna system is configured to receive the downlink signal from the base station, amplified by a repeater, and then transmitted to the user terminal. In the uplink time slot, the antenna system is configured to transmit the signal to the user terminal. The uplink signal from the terminal is amplified by the repeater and forwarded to the base station. If C_TDD is not equal to 1, it is determined whether C_FDD is equal to 1. If C_FDD=1 (that is, a continuous signal is detected at two different and fixed frequency points at the same time, and its power is relatively stable), it is determined to be in FDD mode, and the control antenna system is activated to enable duplexer. If it is determined that C_FDD is not equal to 1, it cannot be determined and further analysis is required, such as extending the observation window, increasing the sampling rate, or using more complex signal processing algorithms to improve the recognition accuracy of signal features.

[0070] In order to flexibly configure the antenna system, in the antenna system configuration method provided in Embodiment 1 of this application, when the target working mode is time division duplex mode, the duration of each time slot in the sampled signal is determined based on a preset synchronization algorithm, and the transmit and receive modes of the antenna system are switched based on the duration; when the target working mode is frequency division duplex mode, the duplexer in the antenna system is enabled, and the frequency of multiple filters of the duplexer is configured.

[0071] Optionally, when the target operating mode is time-division duplex, a high-speed radio frequency switch can be configured to control the antenna's transmit and receive switching.

[0072] Optionally, the wireless signal includes a series of wireless frames with a fixed duration, and a wireless frame includes multiple subframes or time slots.

[0073] In this embodiment of the invention, based on a preset synchronization algorithm, the duration of each time slot in the sampled signal can be determined, such as... Figure 6 As shown, Figure 6 This is a schematic diagram of an optional time slot synchronization control method based on a preset synchronization algorithm according to an embodiment of this application. The preset synchronization algorithm can obtain the radio frame start time by detecting downlink synchronization signals (such as PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal)). And through the downlink slot start time (relative to the start of the radio frame). Uplink timeslot start time (relative to the start of the radio frame) Downlink pre-compensation duration and uplink pre-compensation duration Calculate the local control timing (including the actual control time for opening the downlink channel). and the actual control time for opening the uplink channel. ,Right now , Based on the actual control time, the transmit and receive modes of the antenna system can be switched, such as... Figure 6 As shown, SW_TX controls the antenna to be configured in transmit mode during the actual control time of downlink channel opening to the control time of downlink channel closing (i.e., the time corresponding to the right end of D), and SW_RX controls the antenna system to be configured in receive mode during the actual control time of uplink channel opening to the control time of uplink channel closing (i.e., the time corresponding to the right end of U). To avoid self-interference, mode switching can be performed via a high-speed RF switch. At other times, the antenna system is neither in receive mode nor transmit mode (e.g., ...). Figure 6 The time corresponding to the right end of D in the middle ).

[0074] In this embodiment of the invention, when the target operating mode is frequency division duplex mode, the antenna system is simultaneously connected to both the receiving and transmitting channels of the repeater, and the duplexer in the antenna system is activated, allowing downlink and uplink signals to be transmitted and received simultaneously on different frequency bands without interference. Furthermore, the frequencies of multiple filters in the duplexer can be configured; for example, if the detected downlink frequency is... Uplink frequency is (i.e., the two frequency points corresponding to the difference), the center frequency of the downlink filter can be configured as follows: Configure the center frequency of the uplink filter to The filter bandwidth is configured as follows: ,in, The detected signal bandwidth, This is the minimum protection bandwidth.

[0075] To improve the accuracy of the operating mode configuration, in the antenna system configuration method provided in Embodiment 1 of this application, multiple target operating modes within a time window are collected, and the total number of collections is determined; the number of target operating modes belonging to the same operating mode is determined; based on the total number of collections and the number of modes, the mode stability is calculated; and if the mode stability is less than a preset stability threshold, the time window length is adjusted.

[0076] In this embodiment of the invention, the target operating mode of the fiber optic repeater can be continuously acquired within multiple time windows, and the total number of acquisitions of the target operating mode within all time windows (i.e., the total number of acquisitions) can be counted. ), among all the collected data, count the number of target working modes that belong to the same working mode multiple times consecutively. Based on the total number of data collections and the number of data points, the mode stability (i.e., Stability = ...) can be calculated. When the mode stability is less than the preset stability threshold (i.e.) In cases like 0.8, the time window length is adjusted. For example, the repeater's signal processing unit detects the network signal every 500ms (time window length), continuously collecting 10 operating mode data points, performing a total of 10 mode detections. Eight consecutive results indicate TDD mode, and the remaining two results indicate FDD mode. Therefore, the target number of operating modes belonging to TDD mode is... At this point, Stability equals 0.8, indicating a stable state, and no adjustment to the time window length is required.

[0077] In this embodiment of the invention, adjusting the time window length is to cope with unstable network signals or frequent switching, and to prevent pattern recognition errors caused by unreasonable time window length settings. If the calculated pattern stability is 0.9, the time window length can be reduced to capture signal feature changes in a finer granular manner and improve the accuracy of pattern recognition.

[0078] To prevent service interruption, the switching process can adopt the following steps: First, keep the current configuration working, start the initialization of the new mode in parallel, perform the switch at the service gap or specific synchronization point, and after verifying that the new configuration is working normally, release the old resources. When switching modes, the interruption or performance degradation of communication services should not exceed the preset time budget (e.g., 50ms).

[0079] The antenna system configuration method provided in this application can determine the duplex mode of the current antenna system by continuously monitoring the time-domain characteristics of the signal, such as power variation variance, and the frequency-domain characteristics, including the identification of paired frequency bands and amplitude stability analysis. Once TDD mode is determined, the repeater uses a preset synchronization algorithm to dynamically adjust the transmit and receive modes of the antenna system in the uplink and downlink time slots. If FDD mode is determined, the duplexer can be activated and fine-tuned frequency configuration can be performed to ensure efficient isolation of uplink and downlink signals. In addition, the method can also cope with the instability and frequent switching of network signals through mode stability calculation and intelligent adjustment mechanism of time window length, so that the antenna system is always in the optimal configuration state. This not only improves the deployment flexibility and operation and maintenance efficiency of the repeater, but also optimizes network performance, avoids signal interference, and realizes adaptive antenna configuration.
