[0116] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0117] In the related art, the commonly used automatic gain control technology is essentially a feedback control technology, through which the gain of the amplifier in the repeater can be automatically adjusted so that the amplitude of the output signal of the repeater changes within a specific range. Usually, the automatic gain control system used in the repeater can include three main components: a detector, a controller, and an amplifier; wherein the detector is used to measure the strength of the input signal, the controller is used to calculate and adjust the gain of the amplifier, and the amplifier is used to amplify the input signal.

[0118] However, the above automatic gain control system may have the following problems:

[0119] Problem 1: Since the amount of information measured by the detector of the automatic gain control system is limited, it can usually only measure the strength of the input signal, that is, it can only determine the gain of the output signal based on the strength of the input signal. This makes it impossible to accurately distinguish the characteristics of different signals. Therefore, in some cases, it may not be able to meet the signal amplification requirements, that is, it is impossible to accurately control the amplification gain of the repeater, and thus it is impossible to ensure the quality and stability of wireless communication;

[0120] Question 2: There may be various complex interferences in the signal processing process of the automatic gain control system. Since the detector of the automatic gain control system is usually set at the front end of the RF link (i.e., the input end), additional interference may be introduced into the amplification link, such as adjacent channel leakage ratio (ACLR, Adjacent Channel Leakage Ratio) interference, etc. These additional interferences may affect the output signal of the amplification link after amplification, that is, they may cause output signal distortion, nonlinearity, phase noise, adjacent channel interference and other problems, thereby reducing the performance and reliability of the system.

[0121] Based on this, in various embodiments of the present application, a new automatic gain control system architecture is designed for the repeater (which may be referred to as a gain control system in subsequent descriptions), which can detect one or more index information of the input signal of the repeater, and can also detect one or more index information of the output signal of the repeater. At the same time, the circuit structure is optimized to reduce additional interference. Among them, in response to the above-mentioned problem 1, the detection device of the gain control system detects at least one indicator of the signal to be detected of the repeater (i.e., the input signal and / or output signal of the repeater), and these indicators are associated with the signal quality of the signal to be detected. The control device of the gain control system realizes at least one of controlling the amplification gain of the repeater, switching the signal to be detected between the input signal and the output signal of the repeater, and turning on or off the corresponding uplink communication link and downlink communication link of the repeater based on the detection result obtained by the detection device. In this way, by detecting at least one indicator of the input signal and / or output signal of the repeater, the characteristics (i.e., properties) of the signal can be accurately matched with the amplification requirements, that is, the amplification gain of the repeater can be accurately controlled, thereby improving the reliability and stability of the output signal of the repeater, that is, improving the coverage effect and performance of the repeater, and ensuring the quality and stability of wireless communication.

[0122] Specifically, the embodiment of the present application provides a gain control system, such as Figure 1 As shown, the system includes: a detection device and a control device; wherein,

[0123] The detection device is used to obtain the signal to be detected of the repeater, detect at least one indicator of the signal to be detected, obtain a detection result, and send the obtained detection result to the control device, wherein the at least one indicator is associated with the signal quality of the signal to be detected;

[0124] The control device is used to receive the detection result sent by the detection device, and perform at least one of the following based on the detection result:

[0125] Controlling the amplification gain of the repeater;

[0126] Controlling the signal to be detected obtained by the detection device to switch between the input signal and the output signal of the repeater;

[0127] Control the uplink and downlink communication links corresponding to the repeater to be turned on or off.

[0128] In actual application, the gain control system may also be called a gain adjustment system, an automatic gain control system or an automatic gain adjustment system, etc. The embodiment of the present application does not limit the specific name of the gain control system as long as its function is achieved.

[0129] In actual application, the detection device can specifically detect at least one indicator of the input signal and / or at least one indicator of the output signal of the repeater; the control device can specifically make a joint judgment on at least one indicator of the input signal and / or at least one indicator of the output signal based on specific preset conditions, and perform corresponding operations according to the judgment situation.

[0130] Based on this, in one embodiment, the detection device can be specifically used to obtain the input signal of the repeater, detect at least one indicator of the input signal, obtain a first detection result, and send the first detection result to the control device;

[0131] The control device may be used to control the detection device to obtain the output signal of the repeater when the first detection result satisfies a first condition;

[0132] The detection device may also be used to obtain the output signal of the repeater, detect at least one indicator of the output signal, obtain a second detection result, and send the second detection result to the control device;

[0133] The control device may also be used to control the amplification gain of the repeater according to the second detection result.

[0134] Wherein, in actual application, the first condition may include a threshold value corresponding to each of at least one indicator of the input signal. Specifically, the at least one indicator of the input signal may include RSRP and / or SINR, etc., that is, the first detection result may include indicators such as RSRP and / or SINR of the input signal; then the first condition may include a threshold value corresponding to each of the indicators such as RSRP and / or SINR of the input signal. When each indicator in the first detection result is greater than the corresponding threshold value included in the first condition, the first detection result satisfies the first condition; otherwise, the first detection result does not satisfy the first condition. When the first detection result does not satisfy the first condition, the control device may also control the amplification gain of the repeater.

[0135] Based on this, in one embodiment, the detection device can be specifically used to detect the RSRP and SINR of the input signal;

[0136] The control device can be specifically used to control the detection device to obtain the output signal of the repeater when the RSRP in the first detection result is greater than the first threshold and the SINR is greater than the second threshold; the first condition includes the first threshold and the second threshold.

[0137] In actual application, the specific values ​​of the first threshold and the second threshold can be set according to requirements.

[0138] In one embodiment, the control device may also be used to control the amplification gain of the repeater when the first detection result does not satisfy the first condition.

[0139] In one embodiment, the control device can be specifically used to control the repeater to output a maximum amplification gain when the RSRP in the first detection result is less than or equal to a first threshold, and / or when the SINR in the first detection result is less than or equal to a second threshold; the first condition includes the first threshold and the second threshold.

[0140] In practical application, the maximum amplification gain can be understood as the default gain or initial gain of the repeater, and can also be called the maximum gain; the specific value of the maximum amplification gain can be set according to demand. The control of the repeater to output the maximum amplification gain can be understood as keeping the maximum amplification gain of the repeater unchanged, that is, keeping the attenuation value of the repeater unchanged, and can also be understood as not needing to adjust the amplification gain of the repeater.

[0141] In actual application, at least one indicator of the output signal may include RSRP, etc., that is, the second detection result may include indicators such as RSRP of the output signal; when the control device controls the amplification gain of the repeater according to the second detection result, it can also compare the RSRP and other indicators of the output signal with the corresponding preset thresholds, and control the amplification gain of the repeater according to the comparison result.

[0142] Based on this, in one embodiment, the detection device can be specifically used to detect the RSRP of the output signal;

[0143] The control device can be specifically used to reduce the amplification gain of the repeater when the RSRP in the second detection result is greater than a third threshold.

[0144] In one embodiment, the control device may be specifically used to control the repeater to output a maximum amplification gain when the RSRP in the second detection result is less than or equal to a third threshold.

[0145] In actual application, the specific value of the third threshold can be set according to requirements.

[0146] In one embodiment, the detection device can be specifically used to obtain the output signal of the repeater, detect at least one indicator of the output signal, obtain a third detection result, and send the third detection result to the control device;

[0147] The control device can be specifically used to control the uplink communication link and the downlink communication link corresponding to the repeater to be closed when the third detection result meets the second condition; or, when the third detection result does not meet the second condition, control the uplink communication link and the downlink communication link corresponding to the repeater to be opened.

[0205] In practical application, for the gain control system having the above structure 1 or structure 3, when the detection device (i.e., the detection device 201 or the detection device 401) is implemented by a modem and the control device (i.e., the control device 202 or the control device 402) is implemented by an MCU, for example, Figure 5 The gain control system having the above structure 1 and mode 1 can switch the signal to be detected obtained by the modem 501 (i.e., the detection device 201) between the input signal and the output signal of the downlink amplification link of the repeater by controlling the switch 503 (i.e., the first switch 203) to connect the first input terminal or the second input terminal, thereby switching the gain control system between the above state 1 and state 2; wherein, Figure 5 The gain control system having the above structure 1 and mode 1 is in the on state of the above state 1 as shown in FIG. Figure 8 As shown, in the front-end mode (i.e., the above-mentioned state 1), the modem 501 can collect the relevant parameter information (such as RSRP and / or SINR, etc.) of the input signal of the downlink amplification link through the switch 503, and output the relevant parameter information such as RSRP and / or SINR of the input signal of the downlink amplification link to the MCU 502 (i.e., the control device 202); Figure 5 The gain control system having the above structure 1 and mode 1 is in the on state of the above state 2 as shown in FIG. Fig. 9 As shown, in the backend mode (i.e., the above-mentioned state 2), the modem 501 can collect relevant parameter information (such as RSRP and / or SINR, etc.) of the output signal of the downlink amplification link through the switch 503, and output the relevant parameter information such as RSRP and / or SINR of the output signal of the downlink amplification link to the MCU 502; the MCU 502 can jointly judge the relevant parameter information such as RSRP and / or SINR of the input signal of the downlink amplification link, and the relevant parameter information such as RSRP and / or SINR of the output signal of the downlink amplification link, and calculate the degree of attenuation or amplification of the downlink amplification link to achieve the best signal reception effect, that is, determine how to control the gain of the downlink amplification link.

[0206] In actual application, for the gain control system having the above-mentioned structure 1 or structure 3, when the gain control system is in the back-end mode, that is, when the gain control system is in state 2, since the signal to be detected obtained by the detection device (that is, the detection device 201 or the detection device 401) includes the output signal of the downlink amplification link / uplink amplification link of the repeater, the interference caused by the detection device will not be introduced into the downlink amplification link / uplink amplification link, but can be output through the output end of the downlink amplification link / uplink amplification link, thereby reducing the additional interference in the gain control system, improving the signal-to-noise ratio (that is, SINR) of the output signal, and effectively suppressing problems such as output signal distortion, nonlinearity, phase noise, and adjacent channel interference, thereby further improving the quality and stability of wireless communication. For example, as Fig. 9 As shown, the interference information brought by the modem 501 (ie, the detection device 201) can be transmitted through a back-end CPL (ie, Fig. 9 The CPL 2) output shown will not pass through the amplifier, thereby alleviating the additional interference in the gain control system to a certain extent, improving the signal-to-noise ratio of the output signal of the downlink amplification link of the repeater, and effectively suppressing the signal distortion, nonlinearity, phase noise, adjacent channel interference and other problems of the modem 501.

[0207] In actual application, for the gain control system having the above-mentioned structure 1, the detection device (i.e., the detection device 201) can detect at least one indicator of the input signal of the repeater (such as RSRP and / or SINR, etc.) and / or at least one indicator of the output signal; the control device (i.e., the control device 202) can make a joint judgment on at least one indicator of the input signal and / or at least one indicator of the output signal based on at least one pre-set specific threshold value to control the amplification gain of the repeater.

[0208] Based on this, in one embodiment, for the gain control system having the above structure 1, that is, when the gain control system includes the first switch (that is, the first switch 203), the detection device (that is, the detection device 201) can be specifically used to obtain the input signal of the repeater through the first switch, detect the RSRP and SINR of the input signal, obtain a first detection result, and send the first detection result to the control device (that is, the control device 202);

[0209] The control device may be used to control the first switch to connect the second end when the RSRP in the first detection result is greater than a first threshold and the SINR is greater than a second threshold, so that the detection device obtains the output signal of the repeater through the first switch;

[0210] Correspondingly, the detection device may also be used to obtain the output signal of the repeater through the first switch, detect the RSRP of the output signal, obtain a second detection result, and send the second detection result to the control device;

[0211] The control device may also be used to reduce the amplification gain of the repeater when the RSRP in the second detection result is greater than a third threshold.

[0212] In practical application, the specific values ​​of the first threshold, the second threshold and the third threshold can be set according to the requirements, and the embodiment of the present application does not limit this. In addition, the specific manner in which the control device (i.e., the control device 202) reduces the amplification gain of the repeater can also be set according to the requirements, and the embodiment of the present application does not limit this; illustratively, the control device can use a pre-set specific algorithm to calculate the amplification gain of the repeater after it is reduced.

[0213] In actual application, when the RSRP of the input signal is less than or equal to the first threshold, and / or the SINR of the input signal is less than or equal to the second threshold, or when the RSRP of the output signal is less than or equal to the third threshold, the control device (i.e., the control device 202) can keep the current amplification gain of the repeater unchanged, that is, there is no need to adjust the amplification gain of the repeater. It can be understood that when the RSRP and SINR of the input signal of the repeater are both very good, that is, when the RSRP of the input signal is greater than the first threshold, and the SINR of the input signal is greater than the second threshold, the input signal is a high-quality signal, and it can be considered to combine the RSRP of the output signal of the repeater to comprehensively judge whether it is necessary to reduce the amplification gain of the repeater; when the RSRP of the input signal is less than or equal to the first threshold, and / or the SINR of the input signal is less than or equal to the second threshold, the input signal is not a high-quality signal, and it is necessary to keep the current amplification gain of the repeater unchanged, that is, there is no need to adjust the amplification gain of the repeater. In this way, for the gain control system with the above-mentioned structure 1, the control device controls the amplification gain of the repeater based on the RSRP and SINR of the input signal, which can avoid misjudging the high-quality signal and then erroneously adjusting the amplification gain of the repeater, thereby improving the accuracy of controlling the amplification gain of the repeater, that is, improving the accuracy of the gain control system; at the same time, the control device also combines the RSRP of the output signal to comprehensively judge whether it is necessary to reduce the amplification gain of the repeater, and by introducing the relevant parameters (i.e. RSRP) of the signal amplified by the repeater (i.e. the output signal) into the gain control system, it is possible to further accurately match the characteristics of the signal with the amplification requirements, thereby improving the reliability and stability of the output signal of the repeater, that is, it is possible to improve the coverage effect and performance of the repeater, and to ensure the quality and stability of wireless communication.

[0214] In practical application, for the gain control system having the above structure 1, for the three different control modes (i.e., the above mode 1, mode 2 and mode 3) of the gain control system for the amplification gain of the repeater, the number and value of the first threshold, the second threshold and the third threshold may be the same or different. Figure 5 The gain control system having the above structure 1 and mode 1, and Figure 6 In the gain control system having the above structure 1 and mode 2, the logic of the control device (i.e., the MCU 502 or MCU 602, i.e., the control device 202) controlling the amplification gain of the repeater can be as follows: Fig.10As shown, after the repeater device is turned on, the control device can initialize the gain value (i.e., attenuation value) of the gain control unit (i.e., ATT) to the maximum amplification gain (which can also be understood as a default gain or an initial gain, and the specific value can be set according to the requirements, which is not limited in the embodiment of the present application); the initial state of the first switch (i.e., the switch 503 and the switch 603, i.e., the first switch 203) can be the front-end mode (i.e., the above-mentioned state 1), at which time, the control device can obtain the RSRP and SINR of the signal (i.e., the input signal) received by the repeater detected by the detection device (i.e., the modem 501 and the modem 601, i.e., the detection device 201); the control device can determine whether the input signal satisfies the two conditions that RSRP is greater than a threshold value A (i.e., the first threshold value) and SINR is greater than a threshold value B (i.e., the second threshold value) at the same time, if not, When these two conditions are met at the same time, the control device can keep the attenuation value of ATT unchanged, and the gain control system outputs the maximum amplification gain, that is, the amplification gain of the repeater maintains the maximum gain unchanged; if these two conditions are met at the same time, the control device can control the first switch to switch to the back-end mode (that is, the above-mentioned state 2), and then the control device can obtain the RSRP of the output signal of the repeater detected by the detection device; the control device can determine whether the RSRP of the output signal is greater than the threshold value C (that is, the third threshold value), if the RSRP of the output signal is less than or equal to the threshold value C, the control device can keep the attenuation value of ATT unchanged, and the gain control system outputs the maximum amplification gain, that is, the amplification gain of the repeater maintains the maximum gain unchanged; if the RSRP of the output signal is greater than the threshold value C, the control device can increase the attenuation value of ATT to the gain value output by the gain control system is X. Here, the specific method of calculating X by the control device and / or the specific method of calculating the attenuation value of ATT by the control device can be set according to the needs, for example, a pre-set specific algorithm can be used to calculate X and / or the attenuation value of ATT.

[0215] Or, for Figure 7 In the gain control system having the above structure 1 and mode 3, the logic of the control device (i.e., the MCU 703, i.e., the control device 202) controlling the amplification gain of the repeater can be as follows: Fig.11 As shown, the control device can initialize the gain control unit (i.e. Figure 7The gain value (i.e., attenuation value) of ATT 1 and ATT 2) shown in the figure is the maximum amplification gain (which can also be understood as the default gain or the initial gain, and the specific value can be set according to the requirements, which is not limited in the embodiment of the present application); the initial states of the two first switches (i.e., the switch 704 and the switch 705, i.e., the two first switches 203) can both be the front-end mode (i.e., the above-mentioned state 1), at this time, the control device can obtain the RSRP and SINR of the downlink received signal of the repeater (i.e., the input signal of the downlink amplification link) detected by the two detection devices (i.e., the modem 701 and the modem 702, i.e., the two detection devices 201), and the RSRP and SINR of the uplink received signal of the repeater (i.e., the input signal of the uplink amplification link); for the downlink amplification link, the control device can determine whether the input signal satisfies the two conditions that the RSRP is greater than the threshold value D (i.e., the first threshold value) and the SINR is greater than the threshold value E (i.e., the second threshold value) at the same time, if these two conditions are not met at the same time, the control device can keep ATT 1 remains unchanged, the gain control system outputs the maximum downlink amplification gain, that is, the amplification gain of the downlink amplification link maintains the maximum gain unchanged; for the uplink amplification link, the control device can determine whether the input signal satisfies the two conditions that RSRP is greater than a threshold value F (that is, the first threshold value) and SINR is greater than a threshold value G (that is, the second threshold value) at the same time. If these two conditions are not met at the same time, the control device can maintain ATT 2 remains unchanged, the gain control system outputs the maximum uplink amplification gain, that is, the amplification gain of the uplink amplification link maintains the maximum gain unchanged; if the input signal of the downlink amplification link satisfies the corresponding two conditions at the same time, and the input signal of the uplink amplification link satisfies the corresponding two conditions at the same time, the control device can control both of the two first switches to switch to the back-end mode (that is, the above-mentioned state 2), and then the control device can obtain the RSRP of the output signal of the downlink amplification link and the RSRP of the output signal of the uplink amplification link respectively detected by the two detection devices; for the downlink amplification link, the control device can determine whether the RSRP of the output signal is greater than the threshold value H (that is, the third threshold value), if the RSRP of the output signal is less than or equal to the threshold value H, the control device can keep the attenuation value of ATT1 unchanged, and the gain control system outputs the maximum downlink amplification gain, that is, the amplification gain of the downlink amplification link maintains the maximum gain unchanged; if the RSRP of the output signal of the downlink amplification link is greater than the threshold value H, the control device can increase the attenuation value of ATT 1 to the downlink gain value output by the gain control system to Y1;For the uplink amplification link, the control device can determine whether the RSRP of the output signal is greater than the threshold value I (i.e., the third threshold value). If the RSRP of the output signal is less than or equal to the threshold value I, the control device can keep the attenuation value of ATT 2 unchanged, and the gain control system outputs the uplink maximum amplification gain, that is, the amplification gain of the uplink amplification link maintains the maximum gain unchanged; if the RSRP of the output signal of the uplink amplification link is greater than the threshold value I, the control device can increase the attenuation value of ATT2 to the uplink gain value Y2 output by the gain control system. Here, the specific method by which the control device calculates at least one of the attenuation values ​​of Y1, Y2, ATT 1, and AYY 2 can be set according to requirements, for example, a pre-set specific algorithm can be used to calculate at least one of the attenuation values ​​of Y1, Y2, ATT 1, and AYY 2. ;

[0216] In actual application, for the gain control system having the above-mentioned structure 2, the detection device (i.e., the detection device 301) can detect at least one indicator of the input signal of the repeater (such as RSRP and / or SINR, etc.) or at least one indicator of the output signal; the control device (i.e., the control device 302) can judge at least one indicator of the input signal or at least one indicator of the output signal based on at least one pre-set specific threshold, and control the corresponding uplink communication link and downlink communication link of the repeater to be turned on or off.

[0217] Based on this, in one embodiment, for the gain control system having the above structure 2, that is, when the gain control system includes the second switch (that is, the second switch 303), the detection device (that is, the detection device 301) can be specifically used to detect the RSRP of the output signal of the retransmitting end DUP, obtain a third detection result, and send the third detection result to the control device (that is, the control device 302);

[0218] The control device can be specifically used to control the second switch to be closed when the RSRP in the third detection result is greater than a fourth threshold value, so that the uplink communication link and the downlink communication link corresponding to the repeater are closed; or, when the RSRP in the third detection result is less than or equal to the fourth threshold value, control the second switch to be opened so that the uplink communication link and the downlink communication link corresponding to the repeater are opened.

[0219] Among them, in actual application, the specific value of the fourth threshold value can be set according to demand, and the embodiment of the present application does not limit this. In addition, it can be understood that when the uplink and downlink communication links corresponding to the repeater are closed, that is, when the uplink amplification link and downlink amplification link of the repeater are closed, the output signal of the retransmitting end DUP can also be understood as the downlink signal received by the repeater, or can be understood as the input signal of the repeater; when the uplink and downlink communication links corresponding to the repeater are turned on, that is, when the uplink and downlink amplification links of the repeater are turned on, the output signal of the retransmitting end DUP can also be understood as the downlink signal amplified by the repeater, that is, the output signal of the repeater. In this way, for the gain control system with the above structure 2, since the gain control system can simultaneously control the opening or closing of the uplink communication link and the downlink communication link, the self-excitation phenomenon of the repeater can be avoided, and the two-way energy saving effect and communication quality guarantee can be achieved; at the same time, after the uplink communication link and the downlink communication link are closed, the detection device (i.e., the detection device 301) can still obtain the output signal of the retransmitting end DUP and provide the third detection result to the control device (i.e., the control device 302). When the RSRP in the third detection result is less than or equal to the fourth threshold, the control device can control the second switch (i.e., the second switch 303) to open to open the uplink communication link and the downlink communication link again, thereby ensuring that the repeater can resume work in time when the signal is weak or the blind area is covered, thereby improving the network communication quality; in addition, the interference caused by the detection device can be output by retransmitting ANT without being amplified by the amplifier, thereby reducing the additional interference in the gain control system, improving the signal-to-noise ratio of the output signal, and effectively suppressing the signal distortion, nonlinearity, phase noise, adjacent channel interference and other problems of the detection device.

[0220] In actual application, when the detection device (i.e., the detection device 301) is implemented by a fifth generation mobile communication technology (5G) modem (which can be expressed as 5G mode in English) and the control device (i.e., the control device 302) is implemented by an MCU, exemplarily, Fig.12As shown, the gain control system having the above structure 2 may include: 5G mode 1201 (i.e., the detection device 301), MCU 1202 (i.e., the control device 302), switch 1203 (i.e., the second switch 303), ATT 1204 and CPL 1205; wherein, the switch 1203 is arranged between the retransmission end DUP and the retransmission ANT, and is specifically arranged between the CPL 1205 and the retransmission ANT, so as to simultaneously control the opening or closing of the uplink communication link and the downlink communication link, that is, to simultaneously control the opening or closing of the uplink amplification link and the downlink amplification link; and, it can ensure that the gain control system can still be reopened after being closed, that is, the uplink amplification link and the downlink amplification link are reopened based on the judgment of the signal output from the retransmission end DUP. Specifically, the output signal of the retransmitting end DUP is separated into one path as a control signal after passing through the CPL 1205 and enters the control circuit. The control circuit is used to monitor the signal strength (i.e. RSRP) of the link signal (i.e. the control signal) in real time. The control circuit includes the CPL 1205, ATT 1204, 5G mode 1201 and MCU1202; the control signal enters the 5G mode 1201 after passing through the ATT 1204, and the 5G mode 1201 can demodulate the signal strength information (i.e. the third detection result) from the control signal and output the signal strength information to the MCU 1202; the MCU 1202, as the control core, can determine whether the repeater needs to be turned on according to the signal strength information obtained from the 5G mode 1201; when the signal strength is higher than a specific threshold, that is, when the RSRP in the third detection result is greater than the fourth threshold, the MCU 1202 can control the switch 1203 to be turned off, that is, to control the closure of the uplink communication link and the downlink communication link at the same time, that is, to control the closure of the uplink amplified link and the downlink amplified link at the same time; when the signal strength is less than or equal to a specific threshold, that is, when the RSRP in the third detection result is less than or equal to the fourth threshold, the MCU 1202 can control the switch 1203 to be turned on, that is, to control the opening of the uplink communication link and the downlink communication link at the same time, that is, to control the opening of the uplink amplified link and the downlink amplified link at the same time.In this way, the gain control system can simultaneously control the opening or closing of the uplink communication link and the downlink communication link, thereby avoiding the self-excitation phenomenon of the repeater, and achieving two-way energy saving effect and communication quality assurance; at the same time, after the uplink communication link and the downlink communication link are closed, the 5G mode 1201 can still obtain the downlink signal received by the repeater, that is, obtain the control signal. If the signal strength of the control signal is less than or equal to a specific threshold, the MCU 1202 can control the switch 1203 to turn on, that is, the uplink communication link and the downlink communication link can be turned on again, thereby ensuring that the repeater can resume work in time when the signal is weak or the blind area is covered, thereby improving the network communication quality; in addition, the interference information brought by the 5G mode 1201 can be output through the CPL 1205 and the retransmission ANT, and is not amplified by the amplifier, thereby reducing the additional interference in the gain control system, improving the signal-to-noise ratio of the output signal, and effectively suppressing the signal distortion, nonlinearity, phase noise, adjacent channel interference and other problems of the 5G mode 1201.

[0221] Here, it should be noted that Fig.12 The gain control system having the above structure 2 can be understood as Figure 7 The circuit structure of the gain control system having the above structure 1 and mode 3 is simplified as shown in FIG. Fig.12 The gain control system having the above structure 2 can be understood as Figure 7 In other words, Fig.12 The gain control system having the above structure 2 is shown in FIG. Figure 7 The functions of the gain control system shown in the above structure 1 and mode 3 are similar. Figure 7 The gain control system with the above structure 1 and mode 3, when adjusting the amplification gain of the downlink amplification link and the uplink amplification link of the repeater from the maximum amplification gain (which can also be understood as the default gain or the initial gain) to 0, or from 0 to the maximum amplification gain, actually realizes the opening or closing of the uplink amplification link and the downlink amplification link of the repeater, that is, realizes the opening or closing of the uplink communication link and the downlink communication link corresponding to the repeater, that is, realizes Fig.12 The function of the gain control system having the above-mentioned structure 2 is shown.

[0222] In actual application, for the gain control system having the above-mentioned structure 3, the detection device (i.e., the detection device 401) can detect at least one indicator of the input signal of the repeater (such as RSRP and / or SINR, etc.) and / or at least one indicator of the output signal; the control device (i.e., the control device 402) can make a joint judgment on at least one indicator of the input signal and / or at least one indicator of the output signal based on at least one pre-set specific threshold value, and control the corresponding uplink communication link and downlink communication link of the repeater to be turned on or off.

[0223] Based on this, in one embodiment, for the gain control system having the above structure 3, that is, when the gain control system includes the first switch (that is, the first switch 403) and the second switch (that is, the second switch 404), the detection device (that is, the detection device 401) can be specifically used to obtain the input signal of the repeater through the first switch, detect the RSRP and SINR of the input signal, obtain a fourth detection result, and send the fourth detection result to the control device;

[0224] The control device (i.e., the control device 402) may be used to control the first switch to connect the second end when the RSRP in the fourth detection result is greater than the fifth threshold value and the SINR is greater than the sixth threshold value, so that the detection device obtains the output signal of the repeater through the first switch;

[0225] Correspondingly, the detection device may also be used to obtain the output signal of the repeater through the first switch, detect the RSRP of the output signal, obtain a fifth detection result, and send the fifth detection result to the control device;

[0226] The control device can also be used to control the second switch to be closed when the RSRP in the fifth detection result is greater than a seventh threshold, so that the uplink communication link and the downlink communication link corresponding to the repeater are closed.

[0227] Among them, in actual application, the specific values ​​of the fifth threshold, the sixth threshold and the seventh threshold can be set according to needs, and the embodiments of the present application do not limit this. In addition, it can be understood that when the uplink and downlink communication links corresponding to the repeater are turned on, that is, when the uplink amplification link and the downlink amplification link of the repeater are turned on, when the RSRP of the input signal is less than or equal to the fifth threshold, and / or the SINR of the input signal is less than or equal to the sixth threshold, or when the RSRP of the output signal is less than or equal to the seventh threshold, the control device (that is, the control device 402) needs to keep the uplink and downlink communication links corresponding to the repeater turned on, that is, it is necessary to keep the uplink and downlink amplification links of the repeater turned on, that is, keep the current amplification gain of the repeater unchanged; when the uplink and downlink communication links corresponding to the repeater are turned off, that is, when the uplink and downlink amplification links of the repeater are turned off, the output signal is actually equal to the amplification gain of the repeater. The input signal is the same, that is, the output signal is an unamplified input signal, at this time, the fifth threshold is equal to the seventh threshold, when the RSRP of the input signal is less than or equal to the fifth threshold (this is equivalent to the RSRP of the output signal being less than or equal to the seventh threshold), and / or the SINR of the input signal is less than or equal to the sixth threshold, the control device can control the first switch (that is, the first switch 403) to connect to the second end to obtain the RSRP of the output signal, and control the second switch (that is, the second switch 404) based on the comparison result of the RSRP of the output signal with the seventh threshold, or, the control device can directly control the second switch (that is, the second switch 404) to turn on, so that the uplink communication link and the downlink communication link corresponding to the repeater are turned on, that is, the uplink amplification link and the downlink amplification link of the repeater are turned on. In this way, for the gain control system with the above-mentioned structure 3, since the gain control system can simultaneously control the opening or closing of the uplink communication link and the downlink communication link, it is possible to avoid the self-excitation phenomenon of the repeater, and to achieve two-way energy-saving effects and communication quality assurance; at the same time, after the uplink communication link and the downlink communication link are closed, the control device can control the second switch to open to open the uplink communication link and the downlink communication link again, thereby ensuring that the repeater can resume work in time when the signal is weak or in a blind area, thereby improving the network communication quality.

[0280] It should be noted that the gain control method provided in the above embodiment and the gain control system embodiment belong to the same concept. The specific implementation process of the method is detailed in the gain control system embodiment and will not be repeated here.

[0281] The gain control system and method provided in the embodiments of the present application include a detection device and a control device; wherein the detection device is used to obtain a signal to be detected of a repeater, detect at least one indicator of the signal to be detected, obtain a detection result, and send the obtained detection result to the control device, wherein the at least one indicator is associated with the signal quality of the signal to be detected; the control device is used to receive the detection result sent by the detection device, and perform at least one of the following based on the detection result: control the amplification gain of the repeater; control the signal to be detected obtained by the detection device to switch between the input signal and the output signal of the repeater; control the corresponding uplink communication link and downlink communication link of the repeater to be turned on or off. In the solution provided by the embodiment of the present application, the detection device of the gain control system detects at least one indicator of the signal to be detected of the repeater (i.e., the input signal and / or output signal of the repeater), and these indicators are associated with the signal quality of the signal to be detected. The control device of the gain control system realizes at least one of controlling the amplification gain of the repeater, switching the signal to be detected between the input signal and the output signal of the repeater, and opening or closing the corresponding uplink communication link and downlink communication link of the repeater based on the detection result obtained by the detection device. In this way, by detecting at least one indicator of the input signal and / or output signal of the repeater, the characteristics (i.e., properties) of the signal can be accurately matched with the amplification requirements, that is, the amplification gain of the repeater can be accurately controlled, thereby improving the reliability and stability of the output signal of the repeater, that is, improving the coverage effect and performance of the repeater, and ensuring the quality and stability of wireless communication, thereby at least solving the above-mentioned problem 1.

[0282] In addition, the solution provided in the embodiment of the present application proposes three control modes of the gain control system, namely, the downlink mode (i.e., the above-mentioned mode 1), the uplink mode (i.e., the above-mentioned mode 2) and the bidirectional mode (i.e., the above-mentioned mode 3), for the control of the amplification gain of the downlink amplification link and / or the uplink amplification link of the repeater; in the process of realizing automatic gain control, for the connection state of the first switch, two connection states of the gain control system, namely, the front-end mode (i.e., the above-mentioned state 1) and the back-end mode (i.e., the above-mentioned state 2) are proposed; and two control devices are proposed to control the amplification gain program logic of the repeater (i.e., Fig.10 and Fig.11 Logic shown). Compared with the solution in the related art that determines the output signal gain only according to the strength of the input signal, the solution provided in the embodiment of the present application can control the amplification gain of the repeater according to more parameters (such as RSRP and SINR, etc.) of the received signal (i.e., the input signal of the repeater), and can detect the index information of the output signal while detecting multiple index information of the input signal (such as RSRP and SINR, etc.), and control the amplification gain of the repeater according to multiple quality parameters of the input signal and the output signal. In this way, the signal characteristics can be further accurately matched with the amplification requirements, so that the reliability and stability of the output signal can be further improved, that is, the coverage effect and performance of the repeater can be further improved, and the quality and stability of wireless communication can be further guaranteed, so as to at least further solve the above-mentioned problem 1.

[0283] In addition, the scheme provided by the embodiment of the present application, for the gain control system having the above structure 1 or structure 3, when the gain control system is in the back-end mode (i.e., the above state 2), since the signal to be detected obtained by the detection device includes the output signal of the downlink amplification link / uplink amplification link of the repeater, the interference caused by the detection device will not be introduced into the downlink amplification link / uplink amplification link, but can be output through the output end of the downlink amplification link / uplink amplification link; for the gain control system having the above structure 2, the interference caused by the detection device can be output by retransmitting ANT, and is not amplified by the amplifier. In this way, the additional interference in the gain control system can be reduced, the signal-to-noise ratio (i.e., SINR) of the output signal can be improved, and the output signal distortion, nonlinearity, phase noise, adjacent channel interference and other problems can be effectively suppressed, thereby at least solving the above problem 2, and further improving the quality and stability of wireless communication.

[0284] In addition, the scheme provided by the embodiment of the present application, for the gain control system having the above-mentioned structure 2 or structure 3, since the gain control system can simultaneously control the opening or closing of the uplink communication link and the downlink communication link, it can avoid the self-excitation phenomenon of the repeater, and can achieve a two-way energy-saving effect and guarantee of communication quality; and, after the uplink communication link and the downlink communication link are closed, the control device can control the second switch to open, so as to open the uplink communication link and the downlink communication link again, so as to ensure that the repeater can resume work in time when the signal is weak or in a blind area, thereby improving the network communication quality. In this way, the quality and stability of wireless communication can be further improved.

[0285] In addition, the solution provided in the embodiments of the present application can be applied to various business scenarios, such as shipborne signal enhancement equipment (specifically including shipborne Mangebao, etc.), etc. In this way, the signal quality and efficiency can be improved, and the communication cost and maintenance difficulty can be reduced, thereby providing more stable and efficient support for communications in corresponding business scenarios (such as maritime communications, etc.).
