[0059] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0060] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0061] In one exemplary embodiment, such as Figure 1As shown, a voltage configuration method is provided. This is illustrated using the method applied to a target device or a chip / chip module with data processing capabilities as an example. The target device can be a communication device, which may include, but is not limited to, various personal computers, laptops, smartphones, tablets, drones, low-altitude aircraft, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, smart vehicle devices, projection devices, etc. Portable wearable devices may include smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices may include virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The terminal may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The voltage configuration method includes the following steps 102 to 106:

[0062] Step 102: In response to the state switching request of the target device, generate a first trigger command and write the first trigger command to the power trigger address.

[0063] The state switching request is used to indicate a switch from the transmit state to the receive state. The first trigger instruction includes at least the first voltage activation trigger data and the target voltage index corresponding to the target device being in the transmit state. The target device can be a time-division full-duplex device with communication capabilities, such as a device capable of full-duplex communication, or a mobile terminal that can both receive information from other devices and send information to other devices at different times. That is, the terminal can be in a receive state (receive-initiated state) where it can send data for a certain period of time, and in a transmit state (transmit-initiated state) where it can receive data for another period of time. The state switching request of the target device can be triggered by the user to indicate that the target device needs to switch from the transmit state (TX ON) to the receive state (RX ON). The first trigger instruction is an instruction to trigger the voltage activation of the target device in the receive state. The first voltage activation trigger data can be data indicating that the voltage of the target device is activated in the receive state, that is, data indicating that the receive voltage is activated on the target device.

[0064] Specifically, in a T2R scenario, when the target device receives a state transition request, it can be in a transmitting state; only a target device in a transmitting state can receive the state transition request. Upon receiving the request, the target device can determine that it needs to transition from the transmitting state to the receiving state. This requires acquiring first voltage activation trigger data corresponding to the voltage that enables the receiving state, as well as the effective voltage of the target device in the transmitting state. Based on the correspondence between voltage and index, the target voltage index corresponding to this effective voltage is determined. Based on this, the target device can generate a first trigger command based on the first voltage activation trigger data and the target voltage index. This first trigger command is then written to a pre-configured power trigger address that enables the voltage to take effect.

[0065] Optionally, the power configuration address can be the memory address of the voltage configuration register (trigger register). By configuring the power configuration address, when data is written to the power configuration address, the target device can obtain the voltage corresponding to the written data and supply power to the target device, so that the current voltage of the target device is the voltage corresponding to the data. This realizes voltage configuration to the target device and power supply to the power amplifier in the target device, etc.

[0066] Optionally, the target voltage index corresponding to the target device in the transmission state can be determined by pre-setting multiple voltages, each with a corresponding voltage index. This allows the voltage index to be determined based on the voltage of the target device currently in the transmission state. Alternatively, the voltage index can be determined based on the voltage of the power transmitting amplifier in the target device.

[0067] Step 104: In response to the write completion operation of the first trigger instruction at the power trigger address, a query is performed in the preset storage area based on the target voltage index to obtain the voltage of the target level and the backup voltage corresponding to the target level.

[0068] The preset storage area can be a non-volatile memory (NV) area in the target device, meaning that data in this NV area can be permanently or stably stored for a long time. The data stored in the preset storage area can include multiple voltage levels pre-configured for the target device when it is in transmit mode, corresponding to different voltage levels, and backup voltages corresponding to each voltage level. These backup voltages refer to multiple voltage levels usable when the target device is in receive mode, with each voltage level corresponding to a backup voltage. Each voltage level can be a power point. In other words, the preset storage area stores multiple power points configured for the target device, usable in transmit mode, and backup voltages usable in receive mode. The voltage differences between each voltage level are fixed and consistent, as are the differences between each voltage level and its corresponding backup voltage, providing the basis for voltage configuration data to ensure smooth voltage switching during state transitions of the target device.

[0069] Specifically, the target device can write the first trigger instruction to the power trigger address. When it is determined that the first trigger instruction has been written, in response to the completion of the first trigger instruction, the target device can query the voltage of the target range corresponding to the target voltage index in the preset storage area based on the obtained target voltage index, and then determine the backup voltage corresponding to the voltage of the target range.

[0070] Step 106: Configure the voltage value of the target device based on the backup voltage.

[0071] Specifically, the target device can enable the backup voltage, that is, to supply power to the target device based on the voltage value of the backup voltage, so that the current voltage value of the target device is the voltage value corresponding to the backup voltage.

[0072] In the voltage configuration method described above, upon receiving a state switching request, it can be determined that the target device needs to be switched from the transmitting state to the receiving state. By writing a first trigger instruction to the power trigger address, precise hardware addressing can be achieved, enabling rapid voltage activation. By obtaining the receiving state voltage corresponding to the transmitting state voltage based on the voltage index, the speed of state switching and voltage switching can be further improved. By configuring this backup voltage for the target device, a smooth switch between the transmitting state voltage and the receiving start state voltage can be achieved during the state switching process, realizing precise voltage control for the target device.

[0073] In one embodiment, before the step of generating a trigger instruction in response to a state transition request from the target device, such as Figure 2 As shown, the voltage configuration method also includes:

[0074] Step 202: In response to the start request of the target device's transmission state, a second trigger instruction is generated based on the voltage index and the second voltage activation trigger data, and the second trigger instruction is written to the power trigger address.

[0075] The target device's transmit state activation request is an instruction or request instructing the target device to be in transmit state. The voltage index can be determined based on a user-defined voltage value; for example, a pre-defined correspondence between voltage values ​​and voltage indices can be used to determine the voltage index corresponding to the actual voltage value. The second voltage activation trigger data can be data indicating that the voltage is effective in the target device's transmit state, i.e., data used to indicate that the transmit voltage is effective on the target device. For example, it can be data from the transmit state activation bit in the power trigger address, i.e., data from the transmit state activation bit in the power trigger address.

[0076] Specifically, when the target device receives a request to initiate transmission, or determines that it needs to switch to transmission mode, or determines that it needs to send information to other devices, the target device obtains the currently configured voltage value, determines the voltage index corresponding to the voltage value based on the correspondence between the voltage value and the voltage index, and generates a second trigger command based on the voltage index and the second voltage activation trigger data of the transmission state activation bit in the power trigger address. The specific process of generating the second trigger command is similar to that of generating the first trigger command and will not be repeated here. Based on this, the target device can write the second trigger command into the power trigger address pre-configured for the target device.

[0077] Step 204: In response to the write completion operation of the second trigger command, query the voltage of the target level corresponding to the voltage index in the voltage configuration level data stored in the preset storage area, and configure the voltage of the target level for the target device.

[0078] Specifically, the target device can write the second trigger instruction to the power trigger address. When it is determined that the second trigger instruction has been written, in response to the completion of the writing operation of the second trigger instruction, the target device can determine the voltage of the target level corresponding to the voltage index based on the voltage index carried in the second trigger instruction and the correspondence between the voltage of each target level and the voltage index stored in the preset storage area. This allows the voltage of the target level to take effect, that is, to supply power to the target device based on the voltage value of the target level, so that the current voltage value of the target device is the voltage value corresponding to the target level.

[0079] In this embodiment, the voltage index is used to accurately query the transmission voltage, which improves the query speed of the transmission voltage and enables the transmission voltage to take effect quickly and accurately, and also enables precise control of the transmission voltage.

[0080] In one embodiment, prior to the step of initiating a launch request in response to the target device's transmit state, such as Figure 3 As shown, the voltage configuration method also includes:

[0081] Step 302: In response to the voltage configuration request, obtain the maximum voltage of the target device in the transmit state.

[0082] The voltage configuration request can be a request to configure the transmit power voltage and receive power voltage of the target device. The transmit power voltage is the voltage value that the target device can use when it is in the TX ON state. The maximum voltage is the maximum voltage value that can be configured for the target device in the TX ON state. This maximum voltage can be obtained from the tool manual of the power amplifier corresponding to the target device. The tool manual can be the PA datasheet.

[0083] Specifically, in response to the voltage configuration request, the target device can obtain the maximum transmit power voltage corresponding to the target device from the preset tool manual, that is, the maximum voltage value that can be configured for the target device when the target device is in the transmit state.

[0084] Step 304: Based on the first voltage interval, the maximum voltage, and the preset minimum voltage, generate the voltage configuration level data of the target device in the transmit start state.

[0085] The voltage configuration level data includes at least several voltage levels. The first voltage interval can be a preset voltage interval value, such as 0.1V; the preset minimum voltage has a similar meaning to the maximum voltage, and is the minimum voltage value that can be configured for the target device in TXON state, such as 0.1V.

[0086] Specifically, the target device can determine a voltage range based on the maximum voltage and the preset minimum voltage, and divide the voltage range according to the first voltage interval to obtain multiple voltage levels. Based on this, the voltage levels of each level constitute the target device's transmission start-up voltage configuration level data.

[0087] Optionally, the specific process may involve determining a configurable voltage range based on the maximum voltage and a preset minimum voltage. The configurable voltage range is then divided based on a first voltage interval to obtain multiple voltage levels. In other words, the terminal can determine a first boundary voltage value based on the maximum voltage, a second boundary voltage value based on the preset minimum voltage, and obtain multiple transmit power voltages that can be configured for the target device based on the first and second boundary voltage values. This yields configurable voltage / voltage configuration level data for multiple levels of the target device in the transmit-in-progress state. Within this configurable range, the terminal can start from any boundary value and proceed towards another boundary value, dividing the range multiple times according to the first voltage interval to obtain multiple voltage values, i.e., multiple voltage levels.

[0088] Optionally, the target device can start from the maximum voltage and divide it into multiple steps with a preset value as step until it reaches the preset minimum voltage, thus obtaining multiple voltage values, which are the transmission power voltage values ​​of the target device at multiple levels.

[0089] Step 306: Configure the power trigger address for the target device.

[0090] Specifically, the power trigger address is the power enable address of the target device. The power trigger address includes at least a transmit status enable bit and a receive status enable bit. This power trigger address is the address of the trigger register that enables the voltage, specifically the address of the trigger register that enables the DC-DC converter in the target device. Optionally, this address can be 0x1C01. The DC-DC power supply can be a DC-DC buck-boost power supply used to power various components in the target device (PA / LNA / RF switch). The trigger register is the register that can trigger the voltage and switch the transmit / receive voltage by writing data to the address.

[0091] Step 308: Based on the second voltage interval, calculate the difference between the voltages of each level to obtain the standby voltage corresponding to each level, and store the voltages of each level and the standby voltage in the preset storage area of ​​the target device.

[0092] The second voltage interval represents the difference between the transmit voltage and the receive voltage. For example, it could be 0.1V, or -0.1V. For each voltage level, the voltage at that level is greater than the corresponding backup voltage. In other words, for each voltage level, the transmit voltage is greater than the receive voltage, and the difference between the backup voltage and the receive voltage is the value corresponding to the second voltage interval, which is 0.1V. The preset storage area is the NV region of the target device.

[0093] Specifically, for each voltage level—that is, for each transmit voltage / transmit power voltage / power point—the terminal can calculate the difference between that voltage and the second voltage interval, and determine this difference as the backup voltage corresponding to that level, i.e., determine the difference as the receive voltage corresponding to the transmit voltage of that level. The transmit voltage is the voltage value that can be configured for the target device when in TX ON state; the receive voltage is the voltage value that can be configured for the target device when in RX ON state. Based on this, the terminal can store the voltage of each level and the corresponding backup voltage in a preset storage area. Alternatively, the target device can store the TX voltage corresponding to each power point and the RX voltage corresponding to that TX voltage in the NV area as data pairs.

[0094] Optionally, in the NV region of the target device, the voltage is divided from the maximum power of TX to 0.5V in 0.1V steps to obtain the TX voltage corresponding to multiple power points. Then, the difference between each TX voltage and 0.1V is calculated to obtain the RX voltage corresponding to each TX voltage. The difference between the TX voltage and the corresponding RX voltage is fixed and constant. The TX voltage is greater than the RX voltage, that is, RX voltage = TX voltage - 0.1V.

[0095] In this embodiment, by storing the voltage, voltage index, and backup voltage of the receiving state corresponding to each transmission state in the NV area, reliable parameter preservation can be achieved, thereby providing a data foundation for the rapid switching and activation of index-based voltage in subsequent voltage control.

[0096] In one embodiment, the power trigger address is the address of a preset voltage activation register, and the power trigger address also includes a register trigger bit and a voltage index bit. For example... Figure 4 As shown, the specific processing steps of the step "Responding to the state switching request of the target device and generating the first trigger command" include:

[0097] Step 402: In response to the target device's request to switch from the transmit state to the receive state, determine the first voltage activation trigger data for the receive state activation bit, determine the trigger state value for the register trigger bit, collect the voltage of the target device when it is in the transmit state, and determine the target voltage index corresponding to the voltage.

[0098] In this context, the request for the target device to switch from transmit to receive state is the state switching request in a T2R scenario. The receive state activation bit is a flag that enables the target device's receive voltage to take effect; the register trigger bit is a flag that enables the target device to activate its voltage by writing to a register address; the voltage of the target device in transmit state can be its current voltage, i.e., the current transmit voltage of the target device currently in transmit state; the target voltage index can be the index corresponding to the current transmit voltage of the target device, determined based on a preset correspondence between voltage values ​​and indices.

[0099] Specifically, in response to the target device's request to switch from transmit to receive mode, the target device can determine that the receive voltage needs to be activated. Thus, the target device can determine the first voltage activation trigger data based on the receive mode activation bit. For example, the receive mode activation bit could have a first state value of "activated" and a second state value of "invalid." The target device can then determine the data of the receive mode activation bit as the first state value to obtain the first voltage activation trigger data. Similarly, the register trigger bit could have a third state value of "activated" and a fourth state value of "invalid." The target device can then determine the data of the register trigger bit as the third state value to obtain the trigger state value. The target device can obtain the current transmit voltage and then determine the target voltage index corresponding to that current transmit voltage.

[0100] Step 404: Generate a first trigger command based on the first voltage activation trigger data, the trigger status value, and the target voltage index.

[0101] Specifically, the first voltage activation trigger data, the trigger status value, and the target voltage index are combined to obtain a combination result, and the combination result is determined as the first trigger instruction; or, the first voltage activation trigger data, the trigger status value, and the target voltage index are respectively filled into the standard format data of the initialization of the trigger register to obtain a filling result, and the filling result is determined as the first trigger instruction.

[0102] In this embodiment, the generated first trigger command can achieve precise addressing of the DC-DC power supply in the target device, thereby enabling rapid voltage lookup and rapid voltage activation, reducing hardware overhead in the target device, and also reducing the switching latency between different states of the target device.

[0103] In one embodiment, such as Figure 5 As shown, the specific processing steps of the step "generating a second trigger command based on the voltage index and the second voltage activation trigger data" include:

[0104] Step 502: Based on the voltage value indicated by the startup request, determine the configuration voltage index corresponding to the voltage value. Also, determine the second voltage activation trigger data for the transmit status activation bit, and determine the trigger status value for the register trigger bit.

[0105] The voltage value indicated by the start request can be a voltage value that indicates the target device needs to be in the transmission state, that is, the transmission voltage value configured for the target device, such as one that can be configured by the user in advance.

[0106] Specifically, after obtaining the transmit voltage value configured for the target device, the target device can determine the configuration voltage index corresponding to the transmit voltage value based on the relationship between the voltage value and the index. Furthermore, the target device can determine whether the transmit voltage on the target device needs to be activated. Thus, the target device can determine the second voltage activation trigger data for the transmit status activation bit. For example, if the transmit status activation bit can have a fifth status value of 'activated' and a sixth status value of 'invalid', the target device can determine the data of the transmit status activation bit as the fifth status value to obtain the second voltage activation trigger data. Similarly, if the register trigger bit can have a third status value of 'activated' and a fourth status value of 'invalid', the target device can determine the data of the register trigger bit as the third status value to obtain the trigger status value.

[0107] Step 504: Generate a second trigger command based on the second voltage activation trigger data, trigger status value, and configuration voltage index.

[0108] Specifically, the second voltage activation trigger data, trigger status value, and configuration voltage index are combined to obtain a combination result, and the combination result is determined as the second trigger instruction; or, the second voltage activation trigger data, trigger status value, and configuration voltage index are respectively filled into the standard format data of the initialization of the trigger register to obtain a filling result, and the filling result is determined as the second trigger instruction.

[0109] In this embodiment, the generated second trigger command can achieve precise addressing of the DC-DC power supply in the target device, thereby enabling precise querying and rapid activation of multiple different transmit voltages.

[0110] The following describes in detail the specific process of the above voltage configuration with reference to a specific embodiment:

[0111] Step 1: Determine the maximum power voltage of TX ON in memory according to the PA datasheet.

[0112] Step 2: In NV, configure all voltages + voltage-activated trigger registers (DC-CDC default trigger register 0X1C01) from the maximum power voltage to the minimum power voltage of 0.5V at 0.1V steps from TX ON maximum power voltage to 0.5V minimum power voltage.

[0113] Step 3: Define the RX on call voltage position in NV and configure the Trigger register.

[0114] In step 4:

[0115] S4.1 Configure all voltage register values ​​in NV from the maximum power voltage to the minimum power voltage of 0.5V (TX ON) in 0.1V steps.

[0116] S4.2, Voltage-activated trriger register.

[0117] S4.3, increase the TX ON-0.1V voltage register value at the same power point.

[0118] The order of S4.1-S4.3 can be fixed. In step 4, the TX ON register (voltage register) and TX ON trriger (voltage activation trriger) have been configured; the RX ON (TX ON-100mV) trriger has not been configured, and the control word is not effective.

[0119] Step 5: TX ON calls the value of the voltage register corresponding to each power point. RX ON first calls the RX ONTrriger register, and then calls the same power point to increase the TX ON-0.1V voltage register value to achieve a 0.1V step-down solution. In the T2R scenario, RX ON calls the trimer from step 3 and makes the RX ON(TX ON-100mV) register value effective, achieving the 0.1V step-down solution.

[0120] Specifically, in response to the voltage configuration request, the maximum power voltage in the transmit-on state is determined in the datasheet of the corresponding RF power amplifier (the core power amplifier for transmitting signals).

[0121] Based on the preset voltage configuration interval, maximum power voltage, and preset minimum power voltage, the voltage level data is determined. This data includes voltage values ​​for multiple levels, with the difference between each level representing the preset voltage configuration interval. The voltage level data is then stored in the target storage area. This data is permanently stored; for example, it will not be erased after a device restart. The trigger memory address corresponding to the target device is also determined. This power trigger address is used to control the power supply to the target device. The address usage process can involve, in response to a data write command to a register, acquiring the transmit voltage value of the target level corresponding to that command within the NV area, outputting the transmit voltage value, and configuring the transmit voltage value for the device's RF power amplifier.

[0122] In other words, the voltage level data is bound to a preset trigger register. The preset memory address can be the trigger address of the register. As long as an instruction is written to the register through the preset memory address, the corresponding voltage level can be called, so that the register outputs voltage and provides it to the PA, thereby automatically and accurately providing the required transmit voltage value to the RF power amplifier.

[0123] The target device can also configure the voltage position for receiving state activation in the NV region, as well as configure the trigger register. This means the target device's receiving voltage can also be activated through a trigger register; each receiving voltage is bound to a preset trigger register. The preset memory address can be the trigger address of this register. By writing instructions to the register through this preset memory address, the corresponding voltage level can be invoked, causing the register to output voltage and supply it to the PA, thus automatically and accurately providing the required receiving voltage value to the RF power amplifier. In simple terms, when the target device's power module detects that data has been written to this address, it will query the corresponding voltage from the preset storage area and output it to the amplifier, thereby activating the voltage.

[0124] In one example, in NV, all voltage register values ​​can be configured from the maximum power voltage (TX ON) to the minimum power voltage (0.5V), in 0.1V steps. This means that the transmit power voltage values ​​for all levels are pre-configured. Furthermore, the target device can configure a trigger register to activate the voltage of the target device. Additionally, for each of the above transmit power voltage levels, the transmit function voltage value of each level minus 0.1V is added at 0.1V intervals to obtain the receive voltage value (standby voltage / RX ON) corresponding to that transmit power voltage value, where RX ON = TX ON - 0.1V.

[0125] TX ON calls the value of the voltage register corresponding to each power point. RX ON first calls the RX ON Trigger register, and then calls the same power point to increase the TX ON - 0.1V voltage register value. This achieves a 0.1V voltage reduction strategy for the target device switching from transmit to receive state, realizing smooth voltage changes and further ensuring the safe operation of the device and the reliability of communication. In other words, this application provides a new voltage configuration method. In this new voltage configuration method, namely the T2R scenario in the TDD of the LTE / NR system, by executing the steps described in the above embodiments, the RX ON voltage can be achieved as TX ON voltage - 100MV.

[0126] Optionally, the specific configuration method is as follows: Figure 6a As shown, Figure 6b As shown, and Figure 6c As shown, where Figure 6aIt could be a configuration diagram of the DC-DC power supply for the target device when it is in the transmission state. Figure 6b This could be a configuration diagram of the trigger register. Figure 6c This could be a configuration diagram for the DC-DC power supply when switching from transmit to receive mode. Figure 6a In the diagram, the yellow square wave can be a clock signal with a corresponding clock period of 180ns; the numbers in the blue signal represent the time length and are data signals; SSC represents the start condition; SA: 4 represents the communication address of the target device; REG.W represents a write operation to the register; Address: 03 represents the address of the trigger register, which can be 0x03; Data: 24 represents the data written at the timing of the Gates write operation, such as the second trigger instruction; 1 / 0 represents the acknowledgment position, 1 for acknowledgment (ACK), indicating that the power trigger address corresponding to the register has successfully received the instruction; 0 is the stop condition, indicating that the write operation to the register has ended. Figure 6b and Figure 6c Similarly, I will not go into details here.

[0127] Optionally, the TX ON voltage is 0X314, and the corresponding register can be TRRIGER- 0X310, which contains 4 control words, with each voltage separated by a 0.1V interval.

[0128] TX ON voltage 0X6. After the Trigger takes effect, the corresponding received voltage RX ON voltage can be found in address 0X2. The target device can read the corresponding voltage value according to the NV storage address + name. For example... Figure 6d As shown, in the NV storage area, it can be stored in the form of a configuration table, and the base unit of each voltage level in the table is 0.1V; the configuration table has multiple levels of arrays. The first level array can be DCDC_config, which includes 10 elements, from DCDC_config[0] to DCDC_config[9], where each element corresponds to 10 independent voltage configuration levels, which can cover the various ranges of the transmit voltage.

[0129] For each element, for example, for the MIPI array in DCDC_config[9], MIPI_ctrl_word[0] corresponds to the TX ON voltage, MIPI_ctrl_word[1] corresponds to the trigger register, and MIPI_ctrl_word[2] corresponds to the RXon voltage.
