[0044] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0045] It is understandable that in the face of the problem of excessive energy loss when the wireless network card communicates with the wireless router, the relevant technology usually adjusts the transmission power of the wireless network card based on the packet error rate. Specifically, after the STA (terminal station, such as the wireless network card end) sends information to the AP, the AP will feedback an ACK (Acknowledge character) signal to indicate receipt; if the STA does not receive the feedback ACK signal within the specified time, it means that the AP has not received it, so the STA will resend it. In this way, the STA end uses the percentage of the ACK feedback signal and the number of transmissions, which is the PER (packet error rate) to judge the quality of the wireless channel. Then, when the PER is low, the power consumption can be reduced by reducing the transmission power of the STA.

[0046] However, PER is the ratio of the number of erroneously received packets to the number of transmitted packets, and focuses on the actual data transmission errors. It does not directly reflect the quality of the transmitted signal. The indicators used to reflect signal quality are mainly SNR signal-to-noise ratio (or EVM error vector magnitude). In addition, PER needs to accumulate the number of measured packets, which is not a direct reflection of the channel situation. The process is relatively delayed, and the adjustment of the transmit power is also lagging.

[0047] The present application provides a transmission power adjustment method, which includes obtaining a first transmission signal; when the signal strength of the first transmission signal is greater than a first preset threshold, obtaining a power adjustment frame for the transmission power of the wireless network card; determining an adjustment mode for the transmission power of the wireless network card based on an adjustment identifier of the power adjustment frame; and adjusting the transmission power of the wireless network card based on the adjustment mode for the transmission power of the wireless network card. The method can accurately and effectively avoid unnecessary energy loss and realize adaptive adjustment of the transmission power of the wireless network card.

[0048] The present application embodiment provides a method for adjusting transmission power, which is applied to a wireless network card, such as Figure 1 As shown, the method includes:

[0049] S101: Acquire a first transmission signal.

[0050] In this step, refer to Figure 2 As shown, the wireless router (router AP) and the wireless network card (laptop STA) can communicate with each other, the laptop STA can send information to the AP, and the router AP can also send information to the STA. If the embodiment of the present application is applied to the wireless network card, the first transmission signal is a signal sent by the wireless router.

[0051] S102: When the signal strength of the first transmission signal is greater than a first preset threshold, a power adjustment frame for the transmission power of the wireless network card is obtained.

[0052] In this step, refer to Figure 5 As shown, the wireless network card receives Figure 2 After the first transmission signal is sent by the router AP, the signal strength of the first transmission signal is read. It is generally believed that a signal strength of -60dbm is a good strength for normal communication. Taking -60dbm as the first preset threshold, considering that when the wireless transmitter operates below 0dBm, the RF power amplifier will no longer work and its current consumption is relatively small. Therefore, the transmission power of the wireless network card (STA) in the embodiment of the present application can be controlled above 0dBm, and when the signal strength of the AP signal received by the STA end is large, such as greater than -60dBm, the process of adjusting the transmission power of the wireless network card is started. Among them, the transmission power of the wireless network card is adjusted based on the power adjustment frame. For the specific process, please refer to the detailed description of the relevant parts below and will not be repeated.

[0053] S103: Determine an adjustment mode for the transmit power of the wireless network card based on the adjustment identifier of the power adjustment frame.

[0054] In this step, refer to Figure 5As shown, the adjustment identifier of the power adjustment frame carries relevant information for the wireless network card transmit power. Based on the adjustment identifier of the power adjustment frame, the adjustment mode for the wireless network card transmit power can be determined. For the specific process, please refer to the detailed description of the relevant parts below and will not be repeated here.

[0055] S104: Adjust the transmit power of the wireless network card based on the adjustment mode for the transmit power of the wireless network card.

[0056] In this step, there are two adjustment modes for the wireless network card transmit power: increasing mode and decreasing mode. Figure 5 As shown, based on the adjustment mode of the wireless network card transmission power, the wireless network card transmission power can be increased or decreased to avoid excessive and unnecessary energy loss during the communication process.

[0057] In the scheme shown in step S101 to step S104, a first transmission signal is obtained; when the signal strength of the first transmission signal is greater than a first preset threshold, a power adjustment frame for the transmission power of the wireless network card is obtained; based on the adjustment identifier of the power adjustment frame, an adjustment mode for the transmission power of the wireless network card is determined; based on the adjustment mode for the transmission power of the wireless network card, the transmission power of the wireless network card is adjusted. It can accurately and effectively avoid unnecessary energy loss and realize adaptive adjustment of the transmission power of the wireless network card.

[0058] In an optional solution, determining the adjustment mode for the transmit power of the wireless network card based on the adjustment identifier of the power adjustment frame includes:

[0059] When the adjustment identifier of the power adjustment frame is the first identifier, determining that the adjustment mode for the transmit power of the wireless network card is an increasing mode;

[0060] When the adjustment identifier of the power adjustment frame is the second identifier, it is determined that the adjustment mode for the transmit power of the wireless network card is a decreasing mode.

[0061] In this application, the adjustment identifier can be understood as the ID of the power adjustment frame. This embodiment defines a private power management frame based on the existing WIFI (wireless) protocol to adjust the transmission power of the wireless network card. The WIFI protocol itself has a power control protocol, but its protocol only limits the maximum transmission power. Its purpose is to require the network card to reduce the transmission power to reduce interference with military radar equipment. This embodiment retains the fields with IDs 17-31 in the original protocol and only defines individual fields therein. Figure 3 and Figure 4 , Figure 3 The schematic diagram of the adjustment identifier of the power adjustment frame is the second identifier, such as Figure 3 As shown, Figure 3The Frame Control field is located at the beginning of the frame and occupies 2 bits (bytes). It is used to define the frame type, subtype, protocol version, frame direction and some control flags. Duration / ID occupies 2 bits and is used to specify the network allocation vector timer of other nodes in the network, which is used to control media access. Address1 occupies 6 bits and often represents the MAC address of the receiver of the frame. Address2 occupies 6 bits and often represents the MAC address of the sender of the frame. Address3 occupies 6 bits and can represent different addresses depending on the frame type. Sequence Control occupies 2 bits and is used for frame sequence control and fragment management. Category occupies 1 bit to indicate the type of frame. Action occupies 1 bit to specify the specific action type. Dialog Token occupies 1 bit to receive the data request of the communication partner. FCS occupies 4 bits and is used for error detection during data transmission. TPC Decrease Element includes Element ID (adjustment identifier, occupies 1 bit) and Length (length, occupies 1 bit). The adjustment identifier Element ID is the second identifier, specifically ID No. 30 in the WIFI protocol, and its binary representation is 0×1E. This field is an empty field, that is, no data is stored, so its length is 0, and its binary representation is 0×00. Figure 4 The schematic diagram of the adjustment identifier of the power adjustment frame is the first identifier, such as Figure 4 As shown, Figure 4 Zhongyu Figure 3 For the same parts, see the above Figure 3 The relevant instructions are not repeated here. Figure 4 The TPC Increase Element includes Element ID (adjustment identifier, occupying 1 bit) and Length (length, occupying 1 bit). The adjustment identifier Element ID is the first identifier, specifically ID No. 31 in the WIFI protocol, and its binary representation is 0×1F. This field is an empty field, that is, no data is stored, so its length is 0, and its binary representation is 0×00. In other words, the embodiment of the present application modifies the 30th and 31st fields in the WIFI protocol, defines the 30th field as a descending field, and defines the 31st field as an ascending field. In this way, it is determined whether the adjustment mode for the wireless network card transmit power is an ascending mode or a descending mode, and the adaptive adjustment of the wireless network card transmit power can be realized conveniently and quickly. In addition, the private management frame in the embodiment of the present application is fully compatible with the original WIFI protocol and will not affect other STAs.

[0062] In an optional solution, adjusting the transmit power of the wireless network card based on the adjustment mode for the transmit power of the wireless network card includes:

[0063] Based on the adjustment mode and adjustment step size for the transmit power of the wireless network card, the transmit power of the wireless network card is adjusted.

[0064] In the present application, after determining the adjustment mode for the transmission power of the wireless network card, the transmission power of the wireless network card is adjusted accordingly based on the adjustment step size. Exemplarily, assuming that the adjustment step size is 1dB, when the adjustment mode is the rising mode, the transmission power of the wireless network card is increased by 1dB. When the adjustment mode is the falling mode, the transmission power of the wireless network card is reduced by 1dB. The transmission power can be adjusted step by step based on the adjustment step size, thereby accurately and effectively avoiding unnecessary energy loss.

[0065] In an optional solution, the power adjustment frame is obtained by comparing the sum of a reference signal-to-noise ratio and a preset redundancy value with a target signal-to-noise ratio through a wireless route; the wireless route is a route for communicating with the wireless network card.

[0066] In this application, reference Figure 6 As shown, the power adjustment frame is sent to the wireless network card through the wireless router. Specifically, the wireless router determines the power adjustment frame by comparing the sum of the reference signal-to-noise ratio and the preset redundancy value with the target signal-to-noise ratio. The preset redundancy value is an empirical value, usually set to 3dB. The target signal-to-noise ratio is the signal-to-noise ratio of the transmission signal (the second transmission signal described below) received by the wireless router from the wireless network card. The reference signal-to-noise ratio is a standard signal-to-noise ratio used for comparison and determination of the power adjustment frame. The reference signal-to-noise ratio and the preset redundancy value are added, and the sum of the two is compared with the target signal-to-noise ratio. When the target signal-to-noise ratio is greater than the reference signal-to-noise ratio + the preset redundancy value, the wireless router sends a power adjustment frame with an adjustment identifier as the second identifier (such as the field of ID No. 30 mentioned above) to the wireless network card. When the target signal-to-noise ratio is less than the reference signal-to-noise ratio + the preset redundancy value, the wireless router sends a power adjustment frame with an adjustment identifier as the first identifier (such as the field of ID No. 31 mentioned above) to the wireless network card. It is simple and easy to implement, and provides a data basis for realizing the adaptive adjustment of the transmission power of the wireless network card. At the same time, it can maintain the maximum throughput rate and improve communication quality.

[0067] In an optional solution, the reference signal-to-noise ratio and the target signal-to-noise ratio are obtained by performing signal analysis on the second transmission signal through the wireless router.

[0068] In this application, reference Figure 6As shown, the wireless network card transmits a second transmission signal to the wireless router. After receiving the second transmission signal, the wireless router performs signal analysis on the signal to obtain the target signal-to-noise ratio and MCS (Modulation and Coding Scheme) of the signal. Different MCSs have corresponding signal-to-noise ratios, i.e., reference signal-to-noise ratios. The corresponding reference signal-to-noise ratio is determined from a preset mapping relationship according to the MCS obtained by analysis. This is convenient and fast, and improves the data processing rate of the wireless router, thereby enabling efficient adjustment of the transmission power of the wireless network card.

[0069] In an optional solution, determining the adjustment mode for the transmit power of the wireless network card based on the adjustment identifier of the power adjustment frame includes:

[0070] Extracting power control information of a field corresponding to the adjustment identifier of the power adjustment frame;

[0071] When the power control information is the first power control information, determining that the adjustment mode for the wireless network card transmit power is an increasing mode;

[0072] When the power control information is the second power control information, it is determined that the adjustment mode for the transmit power of the wireless network card is a decreasing mode.

[0073] In this application, reference Figure 7 As shown, Figure 7 In the above Figure 3 and Figure 4 For the same parts, please refer to the detailed description of the related parts mentioned above and will not be repeated here. Figure 7 The TPC Adjust Element in it includes Element ID (adjustment identifier, occupying 1 bit) and Length (length, occupying 1 bit) and TPC info (power control information, occupying 1 bit). The embodiment of the present application defines ID No. 31 (binary representation is 0×1F). Because it stores power control information, the binary representation of the length is 0×00. Among them, TPC info includes 8 parts (Bit0~Bit7). Among them, the 4 bits Bit0~Bit3 are used for 1~16dB step power control (for example, when Bit 7 is 0, Bit0~3=10, the transmission power of the wireless network card can be directly reduced by 10dB). Bit4~Bit6 are all Reserved and are used to implement other functions of the frame. Bit7 is used to determine the power control field of the power adjustment frame, which can decide whether to increase or decrease the power. Reference Figure 5As shown, extract the power control information of the power adjustment frame, that is, the information in Bit7. When the information in Bit7 is the first power control information, that is, Bit7=1, the adjustment mode for the wireless network card transmit power is the rising mode. When the information in Bit7 is the second power control information, that is, Bit7=0, the adjustment mode for the wireless network card transmit power is the falling mode. In addition, when the adjustment mode for the wireless network card transmit power is the rising mode, when the wireless network card transmit power is already the maximum power at this time, the original power can be maintained. When the adjustment mode for the wireless network card transmit power is the falling mode, when the wireless network card transmit power is already 0dBm at this time, the original power can be maintained. In the present application, power control is implemented using simple information similar to 1 bit, which reduces the difficulty of implementation and reduces the loading overhead of software and hardware.

[0074] The embodiment of the present application also provides a transmission power adjustment device, which is applied to a wireless network card, such as Figure 8 As shown, the device comprises:

[0075] A first receiving unit 801, configured to obtain a first transmission signal;

[0076] The second receiving unit 802 is configured to obtain a power adjustment frame for the transmission power of the wireless network card when the signal strength of the first transmission signal is greater than a first preset threshold;

[0077] A first determining unit 803 is used to determine an adjustment mode for the transmit power of the wireless network card based on the adjustment identifier of the power adjustment frame;

[0078] The adjusting unit 804 is configured to adjust the transmit power of the wireless network card based on the adjustment mode for the transmit power of the wireless network card.

[0079] In an optional scheme, the first determination unit 803 is used to determine that the adjustment mode for the wireless network card transmit power is an increasing mode when the adjustment identifier of the power adjustment frame is a first identifier; when the adjustment identifier of the power adjustment frame is a second identifier, determine that the adjustment mode for the wireless network card transmit power is a decreasing mode.

[0080] In an optional solution, the adjustment unit 804 is used to adjust the transmit power of the wireless network card based on the adjustment mode and adjustment step size for the transmit power of the wireless network card.

[0081] In an optional solution, the power adjustment frame is obtained by comparing the sum of a reference signal-to-noise ratio and a preset redundancy value with a target signal-to-noise ratio through a wireless route; the wireless route is a route for communicating with the wireless network card.

[0082] In an optional solution, the reference signal-to-noise ratio and the target signal-to-noise ratio are obtained by performing signal analysis on the second transmission signal through the wireless router.

[0083] In an optional scheme, the first determination unit 803 is used to extract the power control information of the field corresponding to the adjustment identifier of the power adjustment frame; when the power control information is the first power control information, it is determined that the adjustment mode for the wireless network card transmit power is an increasing mode; when the power control information is the second power control information, it is determined that the adjustment mode for the wireless network card transmit power is a decreasing mode.
