Detailed Implementation

[0031] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0032] The signal processing method, apparatus, electronic device, and storage medium of this disclosure are described below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic flowchart of a signal processing method provided in an embodiment of the present disclosure.

[0034] like Figure 1 As shown, the method includes steps 101-103.

[0035] Step 101: In response to the received communication command, determine the target power adjustment strategy of the transmitting port based on the current transmitting power of the RF unit's transmitting port; wherein, the power adjustment strategy includes: step adjustment of the transmitting power of the transmitting port, and / or: controlling the RF unit to switch the transmission mode of the signal through the processing unit, wherein the transmission mode includes time-division transmission mode and synchronous transmission mode.

[0036] In some embodiments, communication commands are initiated by the user or the system, including but not limited to query commands for obtaining tag information. A radio frequency unit (including but not limited to a remote radio unit (RRU)) transmitter port is a physical interface for transmitting wireless signals. The current transmit power is the power level used by the radio frequency unit transmitter port when executing a communication command. A processing unit is a component for performing calculation and control functions, including but not limited to a building baseband unit (BBU). Step-adjusting the transmitter power of a transmitter port refers to the operation of gradually changing the transmitter power according to a preset power level sequence. Switching the signal transmission mode refers to changing the operating timing relationship between multiple radio frequency unit transmitter ports; time-division transmission mode means that multiple radio frequency unit transmitter ports operate within different time windows, and synchronous transmission mode means that multiple radio frequency unit transmitter ports operate within the same time window.

[0037] The above method allows for the selection of an appropriate power adjustment strategy based on the current transmission power level.

[0038] Step 102: Adjust the current transmission power according to the target power adjustment strategy to obtain the adjusted transmission power.

[0039] In some embodiments, when the target power adjustment strategy is a step adjustment, the adjustment process includes, but is not limited to, gradually increasing the transmit power from an initial power level in a preset order, or gradually decreasing the transmit power from the highest transmit power level in a preset order. When the target power adjustment strategy is a switching transmit mode, the adjustment process includes reconfiguring the operating timing of multiple RF unit transmit ports to operate in a time-division or synchronous mode. The adjusted transmit power may be the power level of a single RF unit transmit port, or it may be the equivalent power level after multiple RF unit transmit ports operate in coordination.

[0040] Using the above method, the transmission power can be adjusted according to the selected strategy.

[0041] Step 103: Based on the adjusted transmission power, a signal is sent to the tag within the coverage area to activate the tag and respond to the communication command.

[0042] In some embodiments, the tag is a passive IoT device that acquires energy by receiving signals transmitted by a radio frequency unit and returns response information. Activating the tag means transmitting a signal of sufficient strength to enable the tag to acquire operating energy and enter a communicable state. Responding to communication commands means that after activation, the tag returns its stored information through methods such as backscattering. Coverage range refers to the spatial area where the radio frequency unit's transmitting port can effectively activate the tag.

[0043] Using the above method, the tag activation and information reading process can be completed using the adjusted transmit power, ensuring that the tag receive power just meets the power supply / demodulation sensitivity, thereby reducing interference to adjacent channel communication services.

[0044] In summary, the signal processing method provided in this disclosure can determine a target power adjustment strategy based on the current transmit power of the radio frequency unit's transmit port in response to a communication command. This includes step-by-step adjustment of the transmit power and / or controlling the radio frequency unit to switch the signal transmission mode through a processing unit. The method then sends a signal based on the adjusted transmit power to activate the tag and respond to the communication command. While ensuring the tag activation effect, this method can effectively reduce interference with communication services in adjacent frequency bands.

[0045] Figure 2 A flowchart illustrating a signal processing method provided in an embodiment of this disclosure is further shown, such as... Figure 2 As shown, the signal processing method includes steps 201-202.

[0046] Step 201: During the process of sending signals to the tags within the coverage area, interference information from adjacent communication systems is monitored.

[0047] In some embodiments, an adjacent communication system refers to a communication system operating in a frequency band adjacent to the target frequency band of the current system. Interference information refers to information reflecting the degree of influence of the signal transmitted by the current system on adjacent communication systems. Monitoring interference information of adjacent communication systems can be achieved by setting up a dedicated monitoring module inside the radio frequency unit. This monitoring module can receive signals from adjacent frequency bands and extract relevant parameters. The monitoring process is synchronized with the process of sending signals to the tag to obtain the interference situation in real time.

[0048] Step 202: If the interference information exceeds a preset range, the duty cycle of the signal is reduced according to a preset control strategy.

[0049] In some embodiments, a preset range refers to a pre-defined range of acceptable interference levels for adjacent communication systems, which can be determined based on the performance requirements of the adjacent communication systems. A preset control strategy refers to rules or steps used to adjust the signal duty cycle, including but not limited to reducing the duty cycle by a fixed percentage or reducing the duty cycle in stages. The signal duty cycle refers to the ratio of signal transmission time to the total time of a signal cycle. Adjusting and reducing the signal duty cycle shortens the proportion of signal transmission time to reduce continuous interference to adjacent communication systems.

[0050] The above method enables the reduction of interference to adjacent communication systems by decreasing the signal duty cycle when interference exceeds the permissible range. This adjustment mechanism allows the system to effectively control the level of interference to adjacent channel communication systems while ensuring its own communication performance.

[0051] Figure 3 A flowchart illustrating a signal processing method provided in an embodiment of this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 101. Figure 3 This may include the following steps: Step 301: If the current transmit power is lower than the first power threshold, determine the target power adjustment strategy as the step adjustment of the transmit power of the transmit port.

[0052] In some embodiments, the first power threshold is a preset power value used to distinguish power adjustment methods. This value can be determined based on factors such as the performance parameters of the radio frequency unit, the tag's power requirements, and the anti-interference capability of adjacent communication systems. If the current transmit power is lower than the first power threshold, it indicates that the transmit power is at a low level, and the tag activation requirement can be met by gradually increasing the power without switching the transmit mode. Stepped adjustment of the transmit port's transmit power specifically involves adjusting it sequentially from the current power level to higher power levels according to a preset power ladder, thereby gradually expanding the coverage area for tag activation.

[0053] Step 302: If the current transmit power reaches or exceeds the first power threshold, determine that the target power adjustment strategy is to control the transmit mode of the radio frequency unit to switch signals through the processing unit.

[0054] In some embodiments, if the current transmit power reaches or exceeds a first power threshold, it indicates that the transmit power is already at a high level. Simply increasing the power may not be more efficient in activating the tag and may increase the risk of interference to adjacent communication systems. The processing unit controls the radio frequency unit to switch the signal transmission mode, and can select an appropriate mode from time-division transmission mode and synchronous transmission mode according to the actual coverage scenario and tag distribution. During the switching of transmission modes, the processing unit sends control commands to the radio frequency unit to adjust the working timing of multiple transmission ports to achieve time-division or synchronous signal transmission.

[0055] The above method can adaptively select the optimal power adjustment strategy based on the transmission power level, which ensures both accurate activation of near-range tags and reliable communication of far-range tags, and achieves targeted optimization for different coverage scenarios.

[0056] Figure 4 A flowchart illustrating a signal processing method provided in an embodiment of this disclosure is further shown. Based on Figure 3 The illustrated embodiment further explains step 301. Figure 4 This may include the following steps: Step 401: Control the transmission power of the transmission port to send a charging signal to the tag starting from the initial power level.

[0057] In some embodiments, the initial power level is a pre-set base power value when the transmitter port is activated, which can be determined based on the power supply sensitivity of the surrounding tags within the coverage area. The charging signal is a wireless signal transmitted by the RF unit's transmitter port to provide power to the tags; the tags convert energy by receiving this signal to maintain operation. Controlling the transmitter port to send the charging signal from the initial power level means that the RF unit outputs a signal according to the initial power, covering the area closest to the transmitter port.

[0058] Step 402: Determine whether the transmission power meets the power enhancement conditions.

[0059] In some embodiments, the power boost condition is a preset rule used to determine whether the transmit power needs to be increased, including but not limited to relevant state parameters at the current power level. The determination process is executed by the processing unit, which collects operating data at the current power level and compares it with the preset condition to determine whether the power boost requirement is met.

[0060] Step 403: If the power increase condition is met, the transmission power is increased to the next power level.

[0061] In some embodiments, the next power level is the next power value in a preset power ladder, which is higher than the current power level. Increasing the transmit power to the next power level means that the radio frequency unit adjusts its output power to a higher level according to the preset power ladder to expand the signal coverage and activate tags farther from the transmit port.

[0062] Step 404: Repeat the above judgment and power boosting steps until the transmission power reaches the first power threshold or the preset termination condition is met.

[0063] In some embodiments, the preset termination condition is a pre-set condition used to terminate the power boosting process, including but not limited to no new tags that can be activated within the coverage area. The judgment and power boosting steps are repeated, that is, the operations of steps 402 to 403 are continuously executed in a loop until the transmit power reaches the first power threshold or the preset termination condition is met, at which point the power boosting process stops.

[0064] In some possible ways, Figure 5 This is a schematic diagram of the interaction process of various units within a base station provided in an embodiment of this disclosure, such as... Figure 5 As shown, the processing unit (BBU) determines whether the power of the radio frequency unit (RRU) exceeds the first power threshold, and then configures the same radio frequency parameters for RRU1 and RRU2, including transmit power and signal duration. After configuration, the charging and querying process of RRU1 is started. RRU1 sends a charging signal to the tag, then sends a communication command and collects tag information. During the process, it determines whether to change the signal transmit power. At the same time, the charging and querying process of RRU2 is started simultaneously. RRU2 sends a charging signal to the tag, then sends a communication command and collects tag information. During the process, it also determines whether to change the signal transmit power.

[0065] Using the above method, the transmission power can be gradually increased according to the initial power level, and the tags within the coverage area can be activated in an orderly manner. At the same time, through the interaction and cooperation of various units within the base station, the charging and inventory processes can be executed in a coordinated manner.

[0066] To further explain Figure 4 In the embodiment shown, the power boosting conditions include at least one of the following: whether a new tag is activated per unit time at the current power level, whether the number of times the charging signal of the same power level is transmitted reaches a preset number threshold, and whether the single continuous charging time exceeds a preset time threshold.

[0067] In some possible ways, Figure 6 This is a schematic flowchart illustrating a step-by-step adjustment of the transmit power of a transmit port, as provided in an embodiment of this disclosure. Figure 6As shown, after the process starts, a charging signal is first transmitted at a fixed power (e.g., 26dBm). Next, it checks if the continuous charging time exceeds AA seconds. If not, it continues transmitting the charging signal at the current power; if it does, it sends a communication command and receives tag feedback signals at the same power. Then, it checks if a new tag is activated and found within BB seconds. If so, it further checks if the number of times the charging signal is transmitted at the same power exceeds CC times. If not, it returns to transmitting the charging signal at the current fixed power; if it does, the process ends. If no new tag is found within BB seconds, the charging signal power is increased to DD (dB). It then checks if the increased power exceeds the first power threshold. If not, it returns to transmitting the charging signal at the adjusted fixed power; if it does, it waits for the BBU to issue a target power adjustment strategy, and then the process ends. Here, AA seconds is the preset time threshold, BB seconds is the unit time, CC times is the preset number of times threshold, and DD (dB) is the preset power increase magnitude.

[0068] In some implementation methods, the parameters AA, BB, CC, and DD can be adjusted according to the actual application scenario. This disclosure provides a method for setting parameter values. The preset time threshold AA (seconds) is calculated using the formula 0.001 × (10 + 2a), where a can be 0, 3, or 5. The specific value of AA can be calculated using this formula. The unit time BB (seconds) is calculated using the formula 1 + b, where b can be 2 or 4. The specific value of BB is determined based on this formula. The preset number threshold CC (number of times) is calculated using the formula 2 + c, where c can be 2, 4, 6, or 8. The specific value of CC is obtained based on this formula. The preset power increase amplitude DD (dB) is fixed at 3. In practical applications, the corresponding values ​​can be selected from the range of values ​​for each parameter based on scenario conditions such as tag density in the coverage area and signal transmission characteristics of the radio frequency unit to adapt to different application requirements. It should be noted that the above is only an exemplary method for setting parameter values ​​provided by this disclosure, and not a limitation on specific parameter value setting methods.

[0069] Through the above process, the transmission power of the transmission port can be adjusted in steps based on conditions such as the single continuous charging time, the activation status of new tags per unit time, and the number of transmissions at the same power. This ensures that the tags are fully activated at the current power level before power is increased, thereby increasing the proportion of time for low-power signal transmission and reducing the interference of high-power signals on the signals of adjacent communication systems.

[0070] Figure 7 A flowchart illustrating a signal processing method provided in an embodiment of this disclosure is further shown. Based on Figure 3 The illustrated embodiment further explains step 302. Figure 7This may include the following steps: Step 501: If the current transmit power reaches or exceeds the first power threshold, but is lower than the maximum transmit power, then the target power adjustment strategy is determined to be to control the radio frequency unit to switch the signal transmission mode to the time-division transmission mode through the processing unit.

[0071] In some embodiments, the maximum transmit power is the highest power value that the RF unit's transmit port can output, determined by the RF unit's hardware performance. If the current transmit power reaches or exceeds a first power threshold but is lower than the maximum transmit power, it indicates that the power is at a relatively high level but has not reached the hardware limit. Time-division multiplexing (TDM) transmission mode can avoid signal overlap interference between multiple RF units. The processing unit controls the RF units to switch to TDM transmission mode, that is, sends timing control commands to multiple RF units, causing each RF unit to transmit signals within different time windows.

[0072] Step 502: If the current transmit power exceeds the first power threshold and reaches the maximum transmit power, then the target power adjustment strategy is determined to be to control the radio frequency unit to switch the signal transmission mode to the synchronous transmission mode through the processing unit.

[0073] In some embodiments, when the current transmit power reaches the maximum transmit power, it indicates that the power of a single radio frequency unit cannot be further increased. In this case, the signal energy of multiple radio frequency units can be superimposed through synchronous transmission mode. The processing unit controls the radio frequency units to switch to synchronous transmission mode, that is, sends synchronous control commands to multiple radio frequency units, so that each radio frequency unit transmits signals within the same time window to enhance the signal strength of the target area.

[0074] In some possible ways, Figure 8 This is a flowchart illustrating a radio frequency unit provided in this disclosure when the transmission mode is either time-division transmission mode or synchronous transmission mode. Figure 8 As shown, after the process starts, a charging signal is transmitted at the maximum transmission power. It is then determined whether the continuous charging time exceeds AA seconds. If it does not exceed AA seconds, the charging signal is transmitted at the highest power. If it does exceed AA seconds, the number of times the charging signal is transmitted at the same power exceeds CC times. If it does exceed CC times, a communication command is sent at the same power and a tag feedback signal is received. Then, it is determined whether a new tag has been found within BB seconds. If so, the process returns to determine whether the number of times the signal is transmitted at the same power exceeds CC times. If not, the process ends. If the number of times the signal is transmitted at the same power does not exceed CC times, a communication command is sent directly at the same power and a tag feedback signal is received before proceeding with the subsequent determination steps.

[0075] Using the above method, an appropriate transmission mode can be selected based on the relationship between the current transmission power, the first power threshold, and the maximum transmission power. At the same time, the coordinated execution of signal transmission and tag query can be achieved through the corresponding process.

[0076] To clearly illustrate the embodiments of this disclosure, based on Figure 7 The illustrated embodiment further explains step 501, wherein the time-division transmission mode includes: The control unit transmits signals to the tag at the maximum transmission power within different time windows according to a preset timing sequence, using multiple overlapping radio frequency units within the control coverage area.

[0077] In some embodiments, Figure 9 This is a schematic diagram of the interaction process of various units within a base station provided in an embodiment of this disclosure, such as... Figure 9 As shown, the BBU first determines whether the RRU power exceeds the first power threshold; then it configures the RF parameters for RRU1, including transmit power and signal duration; after configuration, the charging and querying process of RRU1 is started. RRU1 sends a charging signal to the tag, then sends a communication command and collects tag information. During the process, it determines whether the query is complete; after the querying process of RRU1 is completed, the BBU configures the same RF parameters for RRU2; then the charging and querying process of RRU2 is started. RRU2 sends a charging signal to the tag, then sends a communication command and collects tag information. During the process, it also determines whether the query is complete.

[0078] The above method can control the transmission ports of multiple radio frequency units with overlapping coverage areas to send signals in different time windows according to a preset timing sequence, thereby avoiding overlapping interference caused by the simultaneous transmission of signals from multiple radio frequency units.

[0079] To clearly illustrate the embodiments of this disclosure, based on Figure 7 The illustrated embodiment further explains step 502, wherein the synchronous transmission mode includes: The transmitter ports of multiple radio frequency units are controlled to transmit the signal to the tag at the maximum transmit power within the same time window.

[0080] In some embodiments, Figure 10 This is a schematic diagram of the interaction process of various units within a base station provided in an embodiment of this disclosure, such as... Figure 10As shown, the BBU determines whether to adjust the RRU's transmission mode to synchronous transmission mode; it configures the same radio frequency parameters for RRU1 and RRU2, including transmission power and signal duration; after configuration, the charging process of RRU1 and RRU2 starts simultaneously, with RRU1 sending a charging signal to the tag and RRU2 also sending a charging signal to the tag; after charging is completed, the BBU controls the issuance of communication commands, and RRU1 and RRU2 synchronously receive the information fed back by the tag, and determines whether the query is completed during the process.

[0081] The above method can control the transmitting ports of multiple radio frequency units to send signals within the same time window, thereby superimposing signal energy and increasing the signal strength within the coverage area to activate more tags.

[0082] Figure 11 A flowchart illustrating a signal processing method provided in an embodiment of this disclosure is further shown. Based on Figure 2 The illustrated embodiment further explains step 201. Figure 11 This may include the following steps: Step 601: The monitoring module integrated in the radio frequency unit is used to monitor the service signals in the adjacent frequency band to which the adjacent communication system belongs in real time.

[0083] In some embodiments, the monitoring module is a hardware component integrated within the radio frequency unit, capable of receiving signals from adjacent frequency bands. Its operation is performed in parallel with the process of the radio frequency unit sending signals to the tag, thereby achieving continuous monitoring of service signals in adjacent frequency bands. The adjacent frequency band to which the adjacent communication system belongs refers to the frequency range adjacent to the current system's operating frequency band, which is determined by communication standards or network planning.

[0084] Step 602: Obtain the parameters of the service signal in the adjacent frequency band collected by the monitoring module; wherein the parameters include at least one of signal transmission power, signal duration and service duty cycle.

[0085] In some embodiments, signal transmission power is the power level when adjacent communication systems transmit service signals; signal duration is the transmission duration of a single service signal; and service duty cycle is the ratio of the transmission time of service signals in adjacent frequency bands to the total time. When the monitoring module collects these parameters, it detects and extracts data from the service signals in adjacent frequency bands according to a preset sampling period to obtain the corresponding parameter data.

[0086] Step 603: The collected parameters are sent to the processing unit, which then determines the service activity level and interference risk of the adjacent communication system based on the parameters, and generates an evaluation result of the interference information.

[0087] In some embodiments, after receiving the parameters sent by the monitoring module, the processing unit compares the parameters with preset benchmark values, judges the service activity level of adjacent communication systems by the signal transmission power and service duty cycle, analyzes the impact of the current signal on adjacent communication systems by combining the signal transmission parameters of the current system, determines the risk of interference, and finally integrates the evaluation results of interference information.

[0088] The above method can be used to obtain the service signal parameters of adjacent communication systems in real time, and to assess their interference based on these parameters, providing a basis for subsequent adjustment of signal parameters.

[0089] In some possible ways, Figure 12 This is a schematic diagram of the structure of a radio frequency unit provided in an embodiment of the present disclosure, as shown below. Figure 12 As shown, the monitoring module within the radio frequency unit (RRU) acquires service signals in adjacent frequency bands; after processing the service signals, the monitoring module transmits the relevant data to the interference information assessment module; the interference information assessment module generates interference information assessment results based on the data, and then sends the interference information assessment results to the logic control module; the logic control module interacts with the BBU and simultaneously receives control commands from the BBU; the logic control module transmits the control commands to the transceiver module, which sends signals to the tag and receives feedback information from the tag.

[0090] To clearly illustrate the embodiments of this disclosure, based on Figure 11 The illustrated embodiment further explains step 202, wherein the reduction according to the preset control strategy includes: The radio frequency unit is controlled to adjust the duty cycle of the signal from a first duty cycle to a second duty cycle; wherein the second duty cycle is less than the first duty cycle.

[0091] In some embodiments, the first duty cycle is the percentage of the high-level time of the signal before adjustment, and the second duty cycle is the percentage of the high-level time of the signal after adjustment. The specific values ​​of both can be preset according to the evaluation results of interference information and the power supply requirements of the tag. When controlling the radio frequency unit to adjust the duty cycle, the processing unit sends a duty cycle adjustment command to the transceiver module of the radio frequency unit. The transceiver module changes the high and low level durations of the signal according to the duty cycle adjustment command, completing the switch from the first duty cycle to the second duty cycle. Figure 13 This is a schematic diagram comparing the waveforms before and after signal duty cycle adjustment provided in an embodiment of the present disclosure, as shown below. Figure 13 As shown in the figure, the upper waveform corresponds to the signal state of the first duty cycle, at which time the signal is continuously at a high level and the duty cycle is 100%; the lower waveform corresponds to the signal state of the adjusted second duty cycle, where the signal switches between high and low levels, the duration of the high level is shortened and the duration of the low level is increased, and its duty cycle is less than that of the first duty cycle.

[0092] By using the above method, the continuous interference of the signal to adjacent communication systems can be reduced by decreasing the signal duty cycle, while ensuring that the tag obtains enough energy to maintain operation during the high-level signal period.
