[0019] Embodiment one, as shown in the figure, the present application provides an intelligent cooperative control method for a fusion terminal, the method comprises: Figure 1

[0020] Step S100: Collecting a plurality of network state information of a plurality of fusion communication terminals, the network state information comprising channel state information, device state information and current gain configuration, wherein each fusion communication terminal is connected with a PGA gain control module. ​

[0021] In the embodiment of the present application, when collecting network status information of multiple converged communication terminals, a status information request instruction is sent to all converged communication terminals. After receiving the status information request instruction, each terminal synchronously executes local status monitoring, in which channel status information is obtained by physical layer measurement to acquire received signal strength indication, reference signal received power and reference signal received quality parameters, and device status information is obtained by terminal built-in sensors and status registers to acquire terminal geographic position, battery power and transmit power headroom data, while the current gain configuration is read from the directly connected PGA gain control module register. Each converged communication terminal encapsulates the collected channel status information, device status information and current gain configuration in a predetermined format to obtain multiple network status information.

[0022] In the embodiment of the present application, each converged communication terminal is hard connected with a PGA gain control module, which is used to adjust the gain value of the radio frequency signal processed by the converged communication terminal connected therewith.

[0023] Further, the method provided by the embodiment of the present application further comprises:

[0024] The channel status information includes received signal strength indication, reference signal received power, reference signal received quality and channel impulse response; and the device status information includes terminal geographic position, moving speed, battery power and transmit power headroom.

[0025] In the embodiment of the present application, the channel status information includes received signal strength indication, reference signal received power, reference signal received quality and channel impulse response. The received signal strength indication reflects the intensity of the total power of the received radio frequency signal at a specific frequency point; the reference signal received power is the received power obtained by measuring the cell reference signal; the reference signal received quality is the ratio of the reference signal received power to the total interference noise power in the received frequency band; and the channel impulse response describes the time domain or frequency domain characteristics of the multipath channel experienced by the wireless signal from the transmitting end to the receiving end.

[0026] The device status information is used to describe a parameter set of the physical state and capability of the converged communication terminal. The terminal geographic position is obtained by global navigation satellite positioning technology, and is used to determine the spatial coordinates of the terminal; the moving speed reflects the motion state of the terminal in space; the battery power indicates the remaining power reserve of the terminal; and the transmit power headroom represents the additional transmit power capability that can be provided by the radio frequency power amplifier of the terminal under the current configuration.

[0027] Step S200: based on the network status information, a set of coordinated control instructions for the multiple converged communication terminals are calculated by beamforming synchronous decision, including radio frequency signal phase and amplitude weight vectors for beamforming, and further including gain correction instructions for each terminal.

[0028] In the embodiment of the present application, based on the network state information, the beamforming synchronization decision is calculated to obtain the cooperative control instruction set of the plurality of converged communication terminals. First, the signal synthesis task of the plurality of converged communication terminals is read, and the target direction is parsed and obtained. Then, the optimization objective function of the distributed beamforming of the plurality of converged communication terminals in the target direction is constructed. Subsequently, the network state information of the plurality of converged communication terminals is taken as the state space, and the phase and amplitude weight vector is taken as the action space. The optimal radio frequency signal phase and amplitude weight vector corresponding to each of the plurality of converged communication terminals is solved by an optimization algorithm. Subsequently, according to the radio frequency signal phase and amplitude weight vector, the equivalent signal amplitude backstepping under the link loss is performed, and the result is mapped to the gain correction instruction of the PGA gain control module, and finally the complete cooperative control instruction set including the radio frequency signal phase and amplitude weight vector and the gain correction instruction is formed.

[0029] Further, the method provided by the application embodiment further includes:

[0030] The signal synthesis task of the plurality of converged communication terminals is read, and the target direction is parsed and obtained. The optimization objective function of the distributed beamforming of the plurality of converged communication terminals in the target direction is constructed. Based on the optimization objective function, the network state information of the plurality of converged communication terminals is taken as the state space, and the phase and amplitude weight vector is taken as the action space. The optimal radio frequency signal phase and amplitude weight vector corresponding to each of the plurality of converged communication terminals is solved. According to the radio frequency signal phase and amplitude weight vector, the equivalent signal amplitude backstepping under the link loss is performed, and the result is mapped to the gain correction instruction of the PGA gain control module.

[0031] Further, the method provided by the application embodiment further includes:

[0032] The optimization objective function is to maximize the ratio of the synthesized signal strength to the total power consumption.

[0033] In the embodiment of the present application, first, the signal synthesis task of the plurality of communication terminals is read and the target direction is parsed and obtained. The signal synthesis task of each communication terminal is pre-configured and issued by a control device, and the task description contains the spatial coordinate information of the target receiving point. The target receiving point refers to the receiving position where the signal finally needs to arrive, which is given in the form of azimuth angle and elevation angle, used to represent the spatial position of the target. The azimuth angle and the elevation angle refer to the direction from the communication terminal to the target receiving point, wherein the azimuth angle describes the angle of the target direction in the horizontal direction, and the elevation angle describes the angle of the target direction in the vertical direction. By parsing the azimuth angle and the elevation angle parameters contained in the task, the target direction to which the signal needs to be directed is determined.

[0034] Next, a distributed beamforming optimization objective function of the plurality of communication terminals is constructed, and the objective function aims to maximize the ratio of the synthesized signal strength to the total power consumption. The synthesized signal strength refers to the combined effect of all terminal transmitted signals in the target direction, which is obtained by vector superposition of the signal radiation field strength of each terminal. The total power consumption is composed of the sum of the transmission power and the baseband processing power of each terminal.

[0035] Subsequently, based on the optimization objective function, a state space is constructed with network state information of the plurality of communication terminals, and the state space contains real-time parameters such as received signal strength indication, terminal geographic location, battery power, and transmit power headroom of each communication terminal. The action space is composed of phase and amplitude weight vectors, and the action space contains phase offset and amplitude scaling factor that each communication terminal needs to optimize. Through iterative search in the action space by optimization algorithm, the values of the phase offset and the amplitude scaling factor are constantly adjusted, and finally the optimal radio frequency signal phase and amplitude weight vectors corresponding to the plurality of communication terminals respectively are obtained, which maximize the optimization objective function.

[0036] Finally, according to the radio frequency signal phase and amplitude weight vectors, equivalent signal amplitude back propagation under link loss is performed. In this process, according to the radio frequency signal phase and amplitude weight vectors, the link loss from the plurality of communication terminals to the target receiving point is evaluated, and the required transmit signal amplitude reference is calculated in combination with the amplitude weight vector of each terminal. Then, the equivalent signal amplitude required to be reached by each terminal at the transmit port is back calculated to compensate for the link loss. Finally, through the gain-control code word mapping relationship of the PGA gain control module, the corresponding gain correction instruction is generated.

[0037] Further, in the method provided by the application embodiment, according to the radio frequency signal phase and amplitude weight vectors, the equivalent signal amplitude back propagation under link loss is performed, which is mapped to the gain correction instruction of the PGA gain control module, and further includes:

[0038] Based on the plurality of network state information, the forward link loss from the plurality of fusion communication terminals to the target receiving point is evaluated; according to the amplitude weight vectors corresponding to the plurality of fusion communication terminals respectively, a plurality of transmit signal amplitude references are determined; in combination with the plurality of transmit signal amplitude references and the forward link loss, the equivalent signal amplitude required to be reached by the plurality of fusion communication terminals at the transmit port is back calculated; the gain-control code word mapping relationship stored by the PGA gain control module is called to calculate the gain correction instruction required by the plurality of fusion communication terminals to achieve the equivalent signal amplitude.

[0039] In the embodiment of the present application, based on the terminal geographic position coordinates contained in the plurality of network state information, the three-dimensional space straight line distance between each converged communication terminal and the target receiving point is calculated respectively. Then, according to the communication system operating frequency, the path loss is calculated by using the free space path loss model to obtain the forward link loss of the plurality of converged communication terminals to the target receiving point.

[0040] Next, according to the amplitude weight vector corresponding to each converged communication terminal obtained by the beamforming processing, the normalized amplitude weight value of each terminal is combined with the pre-set reference transmission power value to calculate the transmission signal amplitude reference of each terminal through the power conversion relationship.

[0041] Subsequently, the equivalent signal amplitude required to be reached by the plurality of converged communication terminals at the transmission port is calculated by combining the plurality of transmission signal amplitude references and the forward link loss. In this process, the power value of the transmission signal amplitude reference and the attenuation value of the forward link loss are algebraically added, wherein the transmission signal amplitude reference represents the signal strength required to be transmitted by the terminal under ideal conditions, and the forward link loss represents the power attenuation amount of the signal from the terminal to the target receiving point. By adding these two values, the equivalent signal amplitude required to be achieved by each converged communication terminal at the transmission port is obtained.

[0042] Finally, the gain-control code word mapping relationship table stored in the PGA gain control module is queried, and the calculated equivalent signal amplitude is matched and compared with the gain value in the mapping table to obtain the corresponding digital control code word through the table lookup operation to generate the gain correction instruction required by each converged communication terminal.

[0043] Step S300: The cooperative control instruction set is issued to the corresponding converged communication terminal, and each terminal adjusts the gain value through the PGA gain control module after receiving the gain correction instruction, performs primary amplification on the received radio frequency signal, and then performs phase adjustment and amplitude adjustment according to the radio frequency signal phase and amplitude weight vector to transmit the beamforming signal.

[0044] In the embodiment of the present application, the cooperative control instruction set is first distributed to the corresponding converged communication terminal through the control channel, and the cooperative control instruction set contains the gain correction instruction and the radio frequency signal phase and amplitude weight vector customized for each terminal. Each converged communication terminal receives and analyzes the cooperative control instruction set to extract the gain correction instruction that is exclusive to the terminal, and the gain correction instruction is a digital control signal for controlling the PGA gain control module to adjust the gain value. The terminal sends the gain correction instruction to the PGA gain control module, and the module adjusts the gain value according to the instruction to realize the primary amplification of the input radio frequency signal.

[0045] After the gain adjustment is completed, the converged communication terminal continues to parse the radio frequency signal phase and amplitude weight vector in the cooperative control instruction set, which contains the precisely calculated phase offset and amplitude scaling factor. The terminal adjusts the phase of the primary amplified radio frequency signal according to the phase offset, ensuring that the signals transmitted by each terminal are coherently superimposed in the target direction. At the same time, the signal is adjusted in amplitude according to the amplitude scaling factor, optimizing the sidelobe characteristics of the beamforming pattern. Finally, all converged communication terminals synchronously transmit the radio frequency signals that have undergone the above adjustments.

[0046] Further, the method provided by the application embodiment further comprises, before transmitting the beamformed signal:

[0047] The interference power distribution is obtained by spectrum sensing measurement at the positions corresponding to the plurality of converged communication terminals, and carries frequency band and direction identifiers; the aggregate interference caused by the interference sources to the plurality of converged communication terminals is analyzed based on the interference power distribution; and the radio frequency signal phase and amplitude weight vector and the gain correction instruction are jointly adjusted based on the aggregate interference.

[0048] In the application embodiment, at positions corresponding to the plurality of converged communication terminals, each converged communication terminal scans the designated operating frequency band through its radio frequency receiving link, acquires the signal receiving power of each frequency point using the spectrum analysis function, and measures the angle of arrival of the signal through the antenna array to generate an interference power distribution containing frequency band markers and direction identifiers.

[0049] Next, based on the interference power distribution, the aggregate interference caused by the interference sources to the plurality of communication terminals is analyzed. By combining the interference intensity of each interference source with the angle of arrival of the signal, the total interference received by each terminal is evaluated. Specifically, the aggregate interference refers to the superposition effect of the interference signals of multiple interference sources at each terminal. By using the spatial positions of the plurality of converged communication terminals and the received interference power, the total intensity of the interference borne by each terminal is calculated, thereby evaluating the aggregate interference level received by each terminal. This process obtains the final interference intensity by aggregating the powers of all interference signals.

[0050] Finally, the radio frequency signal phase and amplitude weight vector and the gain correction instruction are jointly adjusted based on the aggregate interference. In this process, the gain correction value is first fixed, and the phase and amplitude weight vector of the radio frequency signal is optimized to suppress the aggregate interference. In this process, the optimized phase and amplitude minimize the interference signals in the target direction, thereby improving the quality of the effective signals. Subsequently, the gain correction value is adjusted to ensure that the signal intensity reaches the expected target, while the phase and amplitude weight vector after optimization is fixed. These two operations are alternately performed until the aggregate interference is suppressed to within a predetermined range, thereby achieving optimized transmission of the signal and effective suppression of the interference. Through this process, the adjustment of the radio frequency signal phase and amplitude weight vector and the gain correction instruction is completed.

[0051] Further, the method provided by the application embodiment further comprises the following steps:

[0052] Step one: fixing the gain correction value, and suppressing the aggregate interference by optimizing the phase and amplitude weight vector of the radio frequency signal; step two: fixing the phase and amplitude weight vector of the radio frequency signal with the adjustment parameter obtained in step one, and optimizing the gain correction value; alternately performing step one and step two until the aggregate interference is suppressed to a preset range.

[0053] In the application embodiment, in step one, the gain correction value of all the fusion communication terminals is first fixed, and the phase and amplitude weight vector of the radio frequency signal is calculated by a convex optimization algorithm. The optimization process aims to suppress the aggregate interference, and by adjusting the phase offset and amplitude scaling factor of each terminal, the multiple terminals form a directional radiation null in the interference direction. After iterative calculation, a set of radio frequency signal phase and amplitude weight vector update values that can effectively reduce the aggregate interference is obtained.

[0054] Then in step two, the radio frequency signal phase and amplitude weight vector obtained in step one is taken as a fixed parameter, and the gain correction value of each fusion communication terminal is recalculated by a power back calculation algorithm. The calculation process is based on the equivalent radiation power requirement of the target direction, and combines the current channel condition to determine the optimal gain configuration required by each PGA gain control module. After calculation, a new set of gain correction instructions is obtained to accurately control the signal transmission power of each terminal.

[0055] The above two steps are alternately performed, and the aggregate interference power level is detected after each iteration. When the aggregate interference power value is detected to be reduced to within a preset threshold range, the optimization process is terminated, and the adjustment of the radio frequency signal phase and amplitude weight vector and the gain correction instruction is completed.

[0056] Further, in the method provided by the application embodiment, the cooperative control instruction set is sent to the corresponding fusion communication terminal, and the method further comprises the following steps:

[0057] A unified cooperative sequence number and time slot marker are embedded in the cooperative control instruction set; after receiving the instruction, the multiple fusion communication terminals return an acknowledgement signal carrying the cooperative sequence number to the control center; after receiving the acknowledgement signals of all the terminals, the control center broadcasts a trigger signal carrying the time slot marker, and after receiving the trigger signal, the multiple fusion communication terminals synchronously perform the gain correction and beamforming operation at the preset time slot starting point.

[0058] In the embodiment of the present application, first, when generating the cooperative control instruction set, a unique cooperative serial number is generated by a numbering generator, and a precise time slot marker is obtained by a system clock, and these synchronization markers are embedded into the cooperative control instruction set issued to each converged communication terminal. The cooperative serial number is used to identify the current control batch, and the time slot marker is used to indicate the preset synchronization execution time point, so as to ensure that all terminals follow a unified time reference.

[0059] After each converged communication terminal receives the cooperative control instruction set, the cooperative serial number is immediately parsed, a confirmation signal containing the cooperative serial number is generated, and the confirmation signal is sent to the control center through the uplink channel. The confirmation signal indicates that the terminal successfully receives the instruction and is ready for execution. The control center can master the terminal readiness state by counting the confirmation signals of different cooperative serial numbers.

[0060] After the control center receives the confirmation signals of all terminals for the current cooperative serial number, the control center issues a trigger signal carrying the same time slot marker through the broadcast channel. After each converged communication terminal receives the trigger signal, the time slot marker is used to calibrate the local clock, and the gain correction operation of the PGA gain control module and the beamforming parameter loading are simultaneously started at the preset time slot starting point, so that the multiple terminals are synchronized and executed within the microsecond level of precision.

[0061] In the embodiment of the present application, as described above, the embodiment of the present application has at least the following technical effects:

[0062] The present application collects multiple network state information of multiple converged communication terminals, and the network state information includes channel state information, device state information, and current gain configuration. Each converged communication terminal is connected to a PGA gain control module. Based on the network state information, a cooperative control instruction set for the multiple converged communication terminals is calculated through beamforming synchronization decision, including a radio frequency signal phase and amplitude weight vector for beamforming, and a gain correction instruction for each terminal. The cooperative control instruction set is issued to the corresponding converged communication terminal. After each terminal receives the gain correction instruction, the gain value is adjusted by the PGA gain control module, the received radio frequency signal is initially amplified, and then the phase and amplitude are adjusted according to the radio frequency signal phase and amplitude weight vector, and the beamforming signal is transmitted. The present application solves the technical problem that the distributed terminal in the prior art cannot effectively realize beam cooperation.
