Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

As a network access device in users' homes, routers generally need to be online for a long time to continuously provide access services and data transmission and forwarding services.

WiFi (Wireless Fidelity, wireless fidelity technology), as a commonly used short-range wireless access technology, has become the preferred connection technology for a variety of home network devices. For example, home terminal devices such as TVs, smart speakers, and home cameras basically all use WiFi Connect to the router for network communication. The current problem is that the transmit power of routing equipment and terminal equipment is transmitted at a preset power. The greater the power, the greater the coverage of WiFi. In order to ensure that the WiFi coverage range is far enough, the preset default power is generally the maximum transmit power that meets the radio frequency indicators under the conditions of meeting regulatory requirements, so the default power is generally relatively high.

As shown in Figure 1, the dotted line marked A indicates the WiFi coverage of the TV, the dotted line marked B indicates the WiFi coverage of the routing device, and the dotted line marked C indicates the WiFi coverage of the smart door lock. Taking the routing device and the TV in Figure 1 as an example, the routing device and the TV are relatively close, and the WiFi coverage range of the TV and the WiFi coverage range of the routing device far exceed the actual distance between them. The communication requirements can also be met by sending data at lower power between the routing equipment and the TV. In this scenario, the higher the sending power, the more energy is consumed. If data is sent at the default power, energy is wasted.

Referring to Figure 2, Figure 2 is a flow chart of a power negotiation method according to an exemplary embodiment. As shown in Figure 2, the power negotiation method is applied to a routing device. The routing device has the ability to support power negotiation. The power The negotiation method includes the following steps.

In step S201, it is determined that the target terminal associated with the routing device has the ability to support power negotiation;

In step S202, power negotiation is performed with the target terminal to obtain the target power used for data transmission with the target terminal.

For example, a routing device is a hardware device that connects two or more networks and acts as a gateway between the networks. It is a dedicated intelligent network device that can read the address in each data packet and then decide how to transmit it. The target terminal can be in the same space as the routing device, and can be a device that cannot be easily moved during use, such as a TV, a smart speaker, a home camera, a smart door lock, etc.

For example, when the routing device and the target terminal perform power negotiation, both the routing device and the target terminal have the ability to support power negotiation, and the target power can be obtained through the power negotiation process. The target power can be the downlink power of the routing device sending data packets to the target terminal, or the uplink power of the target terminal sending data packets to the routing device. It can also include the downlink power of the routing device sending data packets to the target terminal and the target power. The uplink power of data packets sent from the terminal to the routing device.

In this disclosure, a routing device capable of supporting power negotiation determines that a target terminal associated with the routing device has the capability of supporting power negotiation, and performs power negotiation with the target terminal to obtain the target power used for data transmission with the target terminal. In this way, the target power obtained through negotiation is more suitable for data transmission between the routing device and the target terminal, which can further reduce data transmission power consumption while ensuring communication quality, so that the routing device and the target terminal can achieve energy saving effects.

As an optional embodiment, the target power includes the target downlink power used by the routing device to send data packets to the target terminal. Power negotiation is performed with the target terminal to obtain the target power used for data transmission with the target terminal, including:

Send the first test message to the target terminal with the target test downlink power;

When receiving the first response message sent by the target terminal based on the first test message, reduce the target test downlink power to obtain the current test downlink power;

Use the current test downlink power as the new target test downlink power, and perform the step of sending the first test message to the target terminal with the target test downlink power until the first response message sent by the target terminal based on the first test message is not received. When sending the first test message, the test downlink power of the last time the first test message was sent is determined as the target downlink power.

For example, the target test downlink power is the power used by the routing device to test sending data packets to the target terminal. When the target terminal can receive the first test message sent by the routing device with the target test downlink power, it indicates that the coverage corresponding to the target test downlink power can cover the location of the target terminal, and the target terminal can be sent to the routing device according to the first test message. The first response message. When the target terminal cannot receive the first test message sent by the routing device with the target test downlink power, it indicates that the coverage range corresponding to the target test downlink power cannot cover the location of the target terminal.

For example, the target test downlink power here may be a preset transmission power, for example, it may be the maximum transmission power under the condition of meeting regulatory requirements and meeting radio frequency indicators. When the target terminal can receive the first test message sent by the routing device with the target test downlink power, the target test downlink power can be gradually reduced to determine whether the target terminal can receive the first test message sent according to the reduced target test downlink power. Test message.

For example, the routing device sends the first test packet to the target terminal. When the routing device receives the first response message, it determines that the target test downlink power may not be the most appropriate downlink power. It can reduce the target test downlink power to obtain the current test downlink power, and then send the target terminal again with the current test downlink power. The first test message. Among them, the difference between the target test downlink power and the preset power is the current test downlink power, and the preset power is the power value reduced by the target test downlink power in each step.

For example, by reducing the test downlink power each time, the power of the routing device sending the first test packet to the target terminal can be continuously reduced. The current test downlink power is used as the new target test downlink power, and the first test message is sent to the target terminal with the current test downlink power until the first response message sent by the target terminal based on the first test message is not received. At this time, the target terminal cannot receive the first test message, that is, the test downlink power reduced by the routing device does not cover the location of the target terminal. Therefore, the test downlink power of the last time the first test message was sent without receiving the first response message can be determined as the target downlink power of the routing device. After determining the target downlink power, the routing device can send a data packet to the target terminal with the negotiated target downlink power.

For example, the carrier of the power negotiation test message and response message may be a custom data message or a custom action management message.

It is worth mentioning that in order to ensure that the test message is not interfered by other factors in the channel, ensure that the transmission environment is better, and avoid the situation where the test message is sent multiple times and the other end can receive it even if the transmission environment is poor, here The test packets are sent without using the wireless retransmission mechanism, that is, a measurement packet is only sent once. If the peer does not receive it, the transmission is considered failed.

Through the above technical solution, the present disclosure can allow data communication between the routing device and the target terminal through the target downlink power obtained through negotiation. The target downlink power is obtained by reducing the target test downlink power. Therefore, the routing device sends the downlink of the data message to the target terminal. The power is lower, which can save energy on routing equipment.

As an optional embodiment, before sending the first test message to the target terminal with the target test downlink power, the method further includes:

Determine the first target encoding rate for sending the first test message to the target terminal;

According to the first target coding rate, the target test downlink power for sending the first test message to the target terminal for the first time is determined.

For example, the encoding rate is the proportion of useful information in the data stream after the analog signal is sampled, quantized, and encoded. It can characterize the quality of data packets sent between devices. The higher the encoding rate, the higher the quality of the data packets sent and the higher the transmission rate. When the transmission power is high, the quality of the data packets sent may not meet the requirements. The coding rate is generally inversely proportional to the power. Therefore, a higher transmission power can correspond to a lower coding rate, and a lower transmission power can correspond to a higher coding rate. High encoding rate.

For example, power negotiation can be performed on the premise of ensuring the communication bandwidth requirements of the target terminal. The communication bandwidth requirements of different terminals can be customized in advance by the terminal according to the terminal type. For example, a TV may consider the bandwidth requirement of online video at maximum resolution as the communication bandwidth requirement of the TV, while a smart door lock will have very little communication bandwidth requirement if it is only for simple data communication.

For example, the first target encoding rate may be used to ensure that data can be transmitted at a higher transmission rate under a corresponding channel environment. Bandwidth can determine the maximum transmission capacity of a network connection, that is, the upper limit speed of a network connection. The encoding rate is the speed during the actual transmission process, which is limited by various factors such as bandwidth, transmission protocol, and network congestion. Therefore, by using the target test downlink power corresponding to the first target coding rate as the initial test downlink power for power negotiation, the quality of signal transmission can be ensured, and further it can be ensured that the routing device determines the direction to the target terminal under the communication bandwidth requirements of the target terminal. the most suitable transmitting power.

As an optional embodiment, determining the first target encoding rate at which the routing device sends the first test message to the target terminal includes:

Send the second test message to the target terminal at the first target test encoding rate;

When the second response message sent by the target terminal based on the second test message is not received, reduce the first target test encoding rate to obtain the first current test encoding rate;

Use the first current test encoding rate as the new first target test encoding rate, and perform the step of sending the second test message to the target terminal at the first target test encoding rate until receiving the second test message sent by the target terminal based on the second test message. When the second response message is sent, and the second response message includes target information used to indicate that the current test encoding rate meets the downlink communication bandwidth requirements, the test encoding rate for sending the second test message this time is determined as the first target. Encoding rate.

For example, in order to ensure that data can be transmitted at a higher transmission rate, that is, each transmitted data carries a larger amount of information, the first target test encoding rate here can be the maximum encoding rate that meets regulatory requirements and meets radio frequency indicators. The maximum coding rate corresponding to the transmit power. Send measurement packets to the target terminal using the default power corresponding to the maximum coding rate. The default power corresponding to the maximum coding rate is small. The target terminal cannot parse the data packets due to the long distance or packet loss or error in the data packets. , the transmission may fail, and the target terminal will not respond to the second test message, that is, it will not send the second response message to the routing device. The routing device can reduce the test encoding rate and then send the measurement message to the target terminal until it receives the second response message sent by the target terminal in response to the second test message, and then determines the test encoding rate as the first target encoding rate. And the target test downlink power for sending the first test message to the target terminal for the first time can be determined according to the first target coding rate.

Here, the target information includes first information used to inform the routing device that the current test encoding rate does not meet the downlink communication bandwidth requirement and second information used to inform the routing device that the current test encoding rate meets the downlink communication bandwidth requirement. When the target terminal determines whether the communication bandwidth at the current test encoding rate meets the downlink communication bandwidth requirements, if not, the second response message sent by the target terminal to the routing device includes informing the routing device that the current test encoding rate does not meet the downlink communication requirements. If the first information of the bandwidth requirement is received, the routing device can stop the subsequent downlink power negotiation process according to the first information in the second response message. If the target terminal determines that the communication bandwidth at the current test encoding rate meets the downlink communication bandwidth requirements, the second response message sent by the target terminal to the routing device may include second information informing the routing device that the current test encoding rate meets the downlink communication bandwidth requirements. , then the routing device can continue the downlink power negotiation according to the second information in the second response message.

As an optional embodiment, the target power includes the target uplink power used by the target terminal to send data packets to the routing device. Power negotiation is performed with the target terminal to obtain the target power used for data transmission with the target terminal, including:

When receiving the third test message sent by the target terminal with the target test uplink power, send a third response message to the target terminal according to the third test message, so that when the target terminal receives the third response message, Reduce the target test uplink power to obtain the current test uplink power; and use the current test uplink power as the new target test uplink power, and perform the step of sending the third test message to the routing device with the target test uplink power until no route is received. When the device sends the third response message based on the third test message, the device determines the test uplink power of the last time the third test message was sent as the target uplink power;

Receive first notification information sent by the target terminal, where the first notification information includes the target uplink power.

For example, after the routing device and the target terminal complete negotiation on the target downlink power of the data packet sent by the routing device to the target terminal, the target terminal may negotiate with the routing device on the target uplink power of the target terminal on the data packet sent by the routing device. The target test uplink power may be a preset transmit power, for example, it may be the maximum transmit power under the condition of meeting regulatory requirements and meeting radio frequency indicators. When the routing device negotiates the uplink power with the target terminal, if the routing device can receive the third test message sent by the target terminal with the target test uplink power, it indicates that the coverage corresponding to the target test uplink power can cover the location of the routing device. The device may send a third response message to the target terminal according to the third test message.

For example, when the routing device sends the third response message to the target terminal according to the third test message, the target terminal can reduce the target test uplink power and then continue to send the test uplink power to the routing device to negotiate the target terminal's response to the routing device. The most suitable transmit power. After determining the target uplink power, the target terminal can send the first notification information to the routing device. The first notification information includes the target uplink power. When the target terminal sends the first notification information to the routing device, it can send it with the maximum uplink power of the target terminal, or Transmission can be performed at the negotiated target uplink power. Thereafter, the target terminal can send the data packet to the routing device with the negotiated target uplink power.

Here, through the above technical solution, the routing device and the target terminal can perform data communication with the target uplink power obtained through negotiation. The target uplink power is obtained by reducing the target test uplink power, so the energy saving effect on the target terminal can be achieved. In addition, for terminals that may be powered by batteries, such as smart door locks, through the above technical solution, the battery life can be improved and the user experience can be improved in scenarios such as smart door locks and routing devices being in the same room.

As an optional embodiment, after determining the test downlink power of the last time the first test message was sent as the target downlink power, the method further includes:

Send second notification information to the target terminal, where the second notification information includes the target downlink power.

For example, after the target downlink power is determined, the routing device may send second notification information to the target terminal to notify the target terminal to complete the downlink power negotiation, and synchronously notify the target terminal of the determined target downlink transmission power.

As an optional embodiment, the method also includes:

Monitor the downlink rate of data packets sent to the target terminal and the first cache amount of data packets to be sent to the target terminal;

When the downlink rate does not meet the current downlink communication bandwidth demand, or the first cache volume continues to grow within the preset time period, the target downlink power is restored to the maximum downlink power of the routing device.

For example, after the target downlink power negotiation is successful, the routing device can continuously monitor the downlink rate of data packets sent to the target terminal and the first cache amount of data packets to be sent to the target terminal. Once it detects that the downlink rate does not meet the current If the downlink communication bandwidth demand and the first cache amount continue to increase within the preset time period, it is considered that the environment has changed and the downlink communication bandwidth demand of the routing device cannot be met. At this time, the default maximum downlink power of the routing device can be immediately restored to the target terminal. Send data packets. Here, the maximum downlink power of the routing device may be the default power corresponding to the current coding rate.

It is worth noting that after the downlink power returns to the maximum downlink power of the routing device, the downlink power negotiation can be performed again to negotiate a new appropriate target downlink power. In addition, in order to avoid the problem of routing equipment or terminals frequently switching between the negotiated target power and the maximum downlink power caused by frequent changes in the environment, a threshold for switching frequency can be set. When the switching frequency exceeds the preset threshold, the downlink power can be stopped. Negotiate and use the maximum downlink power of the routing device to send data packets to the target terminal without changing it.

As an optional embodiment, determining that the target terminal associated with the routing device has the ability to support power negotiation includes:

Receive an association request message sent by the target terminal, where the association request message includes first identification information used to indicate that the target terminal has the ability to support power negotiation;

According to the first identification information, it is determined that the target terminal has the ability to support power negotiation.

For example, the target terminal will associate with the routing device before using the WiFi of the routing device. During the association process, the routing device and the target terminal can declare to each other that they support the above-mentioned power negotiation capabilities. For example, the target terminal can add Vendor Specific Information Elements (Vendor Specific Information Elements) in the association request message to identify that the target terminal has the ability to support power negotiation. The routing device can also add Vendor in the association response message. Specific IE indicates that the routing device also has the ability to support power negotiation. When the relative position of the routing device and the target terminal is fixed, the channel environment is relatively stable, and the negotiated power is less affected by environmental fluctuations. Since routing devices are generally placed at fixed locations, they can all have the ability to support power negotiation. Target terminals such as televisions, cameras and other terminal equipment are relatively fixed in location, so they may also have the ability to support power negotiation.

For example, when the routing device receives an association request message containing the first identification information sent by the target terminal, it will also send an association response message containing the second identification information to the target terminal. The second identification information is used to represent that the routing device has Ability to support power negotiation.

Referring to Figure 3, Figure 3 is a flow chart of a power negotiation method according to an exemplary embodiment. As shown in Figure 3, the power negotiation method is applied to a target terminal. The target terminal has the ability to support power negotiation. The power The negotiation method includes the following steps.

In step S301, it is determined that the routing device associated with the target terminal has the ability to support power negotiation;

In step S302, power negotiation is performed with the routing device to obtain the target power used for data transmission with the routing device.

In this disclosure, the routing device performs power negotiation with the target terminal to obtain the target power used for data transmission with the target terminal, where both the routing device and the target terminal have the ability to support power negotiation. In this way, the target power obtained through negotiation is more suitable for data transmission between the routing device and the target terminal, which can further reduce data transmission power consumption while ensuring communication quality, so that the routing device and the target terminal can achieve energy saving effects.

As an optional embodiment, the target power includes the target downlink power used by the routing device to send data packets to the target terminal. Power negotiation is performed with the routing device to obtain the target power used for data transmission with the routing device, including:

When receiving the first test message sent by the routing device with the target test downlink power, send the first response message to the target terminal according to the first test message, so that when the routing device receives the first response message, Reduce the target test downlink power to obtain the current test downlink power, and use the current test downlink power as the new target test downlink power, and perform the steps of sending the first test message to the target terminal with the target test downlink power until no route is received. When the device sends the first response message based on the first test message, the device determines the test downlink power of the last time the first test message was sent as the target downlink power;

Receive second notification information sent by the routing device, where the second notification information includes the target downlink power.

For example, when the routing device negotiates the downlink power with the target terminal, if the target terminal can receive the first test message sent by the routing device with the target test downlink power, it indicates that the coverage corresponding to the target test downlink power can cover the location of the target terminal. location, the target terminal can send the first response message to the routing device according to the first test message.

For example, when the target terminal sends the first response message to the routing device according to the first test message, the routing device can reduce the target test downlink power and then continue to send the test downlink power to the target terminal to negotiate the routing device for the target terminal. The most suitable transmit power. When the routing device determines the appropriate target downlink power, it may send second notification information to the target terminal, where the second notification information includes the target downlink power. When the routing device sends the second notification information to the target terminal, it may send it using the maximum downlink power of the routing device, or it may send it using the negotiated target downlink power. Thereafter, the routing device can send the data packet to the target terminal with the negotiated target downlink power.

Through the above technical solution, the present disclosure allows data communication between the routing device and the target terminal using the target downlink power obtained through negotiation. The target downlink power is obtained by reducing the target test downlink power. Therefore, the energy saving effect of the routing device can be achieved.

As an optional embodiment, the target power includes the target uplink power used by the target terminal to send data packets to the routing device. Power negotiation is performed with the routing device to obtain the target power used for data transmission with the routing device, including:

Send the third test message to the target terminal with the target test uplink power;

When receiving the third response message sent by the target terminal based on the third test message, reduce the target test uplink power to obtain the current test uplink power;

Use the current test uplink power as the new target test uplink power, and perform the step of sending the third test message to the target terminal with the target test uplink power until the third response message sent by the target terminal based on the third test message is not received. When sending the third test message, the test uplink power of the last time the third test message was sent is determined as the target uplink power.

For example, the target terminal negotiates the target uplink power with the routing device, and the target terminal can send a third test message to the routing device with the target test uplink power. When the routing device can receive the third test message sent by the target terminal with the target test uplink power, message, indicating that the coverage corresponding to the target test uplink power can cover the location of the routing device. At this time, the routing device can send a third response message to the target terminal according to the third test message. When the routing device cannot receive the third test message sent by the target terminal with the target test uplink power, it indicates that the coverage corresponding to the target test uplink power cannot cover the location of the routing device.

For example, the target test uplink power may be a preset transmission power, for example, it may be the maximum transmission power under the condition of meeting regulatory requirements and meeting radio frequency indicators. When receiving the third response message, the target terminal can reduce the target test uplink power to obtain the current test uplink power. By reducing the test uplink power each time, the power of the target terminal sending the third test packet to the routing device can be continuously reduced. Use the current test uplink power as the new target test uplink power, and send the third test message to the routing device with the current test uplink power until the third response message sent by the routing device based on the third test message is not received. , at this time the routing device cannot receive the third test message, that is, the reduced test uplink power of the target terminal does not cover the location of the routing device. Therefore, the test uplink power of the last third test message sent without receiving the third response message can be determined as the target uplink power for the target terminal to send data to the routing device. After determining the target uplink power, the target terminal can send a data packet to the routing device with the negotiated target uplink power.

Here, through the above technical solution, data can be transmitted at the target uplink power obtained through negotiation between the routing device and the target terminal. The target uplink power is obtained by reducing the target test uplink power, so the energy saving effect on the target terminal can be achieved. In addition, for terminals that may be powered by batteries, such as smart door locks, through the above technical solution, the battery life can be improved and the user experience can be improved in scenarios such as smart door locks and routing devices being in the same room.

As an optional embodiment, determining that the routing device associated with the target terminal has the ability to support power negotiation includes:

Send an association request message to the routing device, so that the routing device sends an association response message containing the second identification information to the target terminal according to the first identification information contained in the association request message. The first identification information is used to characterize the target terminal. Having the ability to support power negotiation, and the second identification information is used to indicate that the routing device has the ability to support power negotiation;

Receive the association response message sent by the routing device, and determine according to the second identification information in the association response message that the routing device associated with the target terminal has the ability to support power negotiation.

As an optional embodiment, after determining the test uplink power of the last time the third test message was sent as the target uplink power, the method further includes:

Send first notification information to the routing device, where the first notification information includes the target uplink power.

For example, after the target terminal determines the target uplink power, it may send the first notification information to the routing device to notify the routing device to complete the uplink power negotiation, and synchronously notify the routing device of the determined target uplink transmission power.

As an optional embodiment, before sending the third test message to the target terminal with the target test uplink power, the method further includes:

Determine the second target encoding rate for sending the third test message to the routing device;

According to the second target coding rate, determine the target test downlink power for sending the third test message to the routing device for the first time.

For example, the second target coding rate may be used to ensure that the target terminal can transmit data to the routing device at a higher transmission rate under a corresponding channel environment. The power negotiation here can also be negotiated on the premise of ensuring the communication bandwidth requirements of the target terminal. The communication bandwidth requirements of different terminals can be customized by the terminal in advance according to the terminal type.

As an optional embodiment, determining the second target encoding rate for sending the third test message to the routing device includes:

Send the fourth test message to the target terminal at the second target test encoding rate;

When the fourth response message sent by the target terminal based on the fourth test message is not received, reduce the second target test encoding rate to obtain the second current test encoding rate;

Use the second current test encoding rate as the new second target test encoding rate, and perform the step of sending the fourth test message to the target terminal at the second target test encoding rate until receiving the fourth test message sent by the target terminal based on the fourth test message. When sending the fourth response message, determine whether the test encoding rate of the fourth test message sent this time meets the uplink communication bandwidth requirements;

The test encoding rate that meets the uplink communication bandwidth requirement is determined as the second target encoding rate.

For example, after the routing device and the target terminal complete negotiation on the target downlink power of the data packet sent by the routing device to the target terminal, the target terminal may negotiate with the routing device on the target uplink power of the target terminal on the data packet sent by the routing device. Similarly, the target terminal negotiates the target uplink power with the routing device, and can send the third test message to the routing device through the target terminal with the target test uplink power. When the routing device can receive the third test message sent by the target terminal with the target test uplink power, message, indicating that the coverage corresponding to the target test uplink power can cover the location of the routing device. At this time, the routing device can send a third response message to the target terminal according to the third test message. When the routing device cannot receive the third test message sent by the target terminal with the target test uplink power, it indicates that the coverage corresponding to the target test uplink power cannot cover the location of the routing device.

For example, when receiving the third response message, the target terminal can reduce the target test uplink power to obtain the current test uplink power. By reducing the test uplink power each time, the power of the target terminal sending the third test packet to the routing device can be continuously reduced. Use the current test uplink power as the new target test uplink power, and send the third test message to the routing device with the current test uplink power until the third response message sent by the routing device based on the third test message is not received. , at this time the routing device cannot receive the third test message, that is, the reduced test uplink power of the target terminal does not cover the location of the target terminal. Therefore, the test uplink power of the last time the third test message was sent without receiving the third response message can be determined as the target uplink power of the target terminal. After determining the target uplink power, the target terminal can send a data packet to the routing device with the negotiated target uplink power.

Here, through the above technical solution, the routing device and the target terminal can perform data communication with the target uplink power obtained through negotiation. The target uplink power is obtained by reducing the target test uplink power, so the energy saving effect on the target terminal can be achieved. In addition, for terminals that may be powered by batteries, such as smart door locks, through the above technical solution, the battery life can be improved and the user experience can be improved in scenarios such as smart door locks and routing devices being in the same room.

As an optional embodiment, the method also includes:

Monitor the uplink rate of data packets sent to the routing device and the second cache amount of data packets to be sent to the routing device;

When the uplink rate does not meet the current uplink communication bandwidth requirement, or the second cache amount continues to grow within a preset time period, the target uplink power is restored to the maximum uplink power of the target terminal.

For example, after the target uplink power negotiation is successful, the target terminal can continuously monitor the uplink rate of data packets sent to the target terminal and the second cache amount of data packets to be sent to the routing device. Once it is detected that the uplink rate does not meet the current If the uplink communication bandwidth requirement is required and the second cache amount continues to grow within the preset time period, it is considered that the environment has changed and the uplink communication bandwidth requirement of the target terminal cannot be met. At this time, data can be immediately restored to the maximum uplink power of the target terminal to send data to the routing device. message. Here, the maximum uplink power of the target terminal is the default power corresponding to the current coding rate.

It is worth noting that after the uplink power is restored to the maximum uplink power of the target terminal, the above-mentioned uplink power negotiation method can be performed again to negotiate a new appropriate target uplink power. In addition, in order to avoid the problem of terminals frequently switching between the negotiated target power and the maximum uplink power caused by frequent changes in the environment, a threshold for switching frequency can be set. When the switching frequency exceeds the preset threshold, the uplink power negotiation can be stopped and Use the maximum uplink power to send data packets to the routing device without changing it.

It is worth noting that only one of the uplink power negotiation and the downlink power negotiation can be performed, or both of them can be performed. Uplink power negotiation and downlink power negotiation do not affect each other. The order of uplink power negotiation and downlink power negotiation is not limited, but in order to ensure that the WiFi of the routing device can be used by the target terminal, the uplink power negotiation can be performed first and then the downlink power negotiation can be performed.

As an exemplary embodiment, referring to Figures 4-6, a power negotiation method is shown according to an exemplary embodiment, so that the routing device and the terminal can negotiate appropriate transmit power based on the terminal's data communication bandwidth requirements.

Among them, AP (Access Point, wireless access point) here can represent the routing device, and STA (Station, in communication, refers to a terminal device in a communication system) can represent the target terminal. That is, during the association process, the AP and STA can declare to each other that they have the ability to support power negotiation. When the relative position of the AP and STA is fixed, the channel environment is relatively stable, and the negotiated power is less affected by environmental fluctuations. Since the routing device is placed at a relatively fixed location, it can declare its ability to support power negotiation. Terminal devices such as TVs and cameras have relatively fixed positions, so they can also claim to have the ability to support power negotiation. For example, the VendorSpecific IE identifier can be added to the association request message sent by the STA to the AP to support power negotiation, and the AP can add the VendorSpecific IE identifier to the association response message sent to the STA to support power negotiation.

When the AP and STA declare to each other that they have the ability to support power negotiation and complete the association, the AP or STA can start to initiate downlink power negotiation or uplink power negotiation. Referring to Figure 4 and Figure 5, downlink power negotiation is to negotiate the appropriate transmit power of the AP and is initiated by the AP. Among them, the AP can send measurement packets to the STA at the default power a corresponding to the maximum coding rate A. If the transmission fails, that is, no response packet from the STA is received, the AP can reduce the coding rate and use the reduced coding rate B corresponding to The default power b is used to send measurement packets to the STA until a response packet from the STA is received. If the STA's response message can be received at the default power a corresponding to the maximum coding rate A, the subsequent downlink power negotiation process can be performed at the default power a corresponding to the maximum coding rate A. Here, the maximum coding rate A is greater than the coding rate B, and the default power a is smaller than the default power b. In addition, after receiving the measurement message sent by the AP, the STA can determine whether the communication bandwidth at this coding rate can meet the downlink communication bandwidth requirements. If not, the STA sends a measurement response message to the AP to inform that the communication bandwidth is not met. demand, stop subsequent downlink power negotiation. Afterwards, the AP sends data to the STA at the maximum transmit power; if the communication bandwidth of the above coding rate meets the requirements, the STA sends a measurement response message to the AP to inform the AP that the current coding rate meets the downlink communication bandwidth requirements.

Among them, according to the different radio frequency rate configurations in MCS (Modulation and Coding Scheme), each MCS index corresponds to the physical transmission rate under a set of parameters. For example, the maximum coding rate A can be the maximum transmission rate corresponding to MCS7, for example, it can be 135.0Mb/s-150.0Mb/s, and the coding rate B can be between MCS0 and MCS6, for example, it can be 13.5Mb/s-135.0Mb/ s. The default power corresponding to coding rate A can be 9dbm, and the default power corresponding to coding rate B can be 7dbm. The coding rate data and default power data here are only examples and are not intended to limit this embodiment.

Taking the downlink power negotiation process shown in Figure 5 as an example, after determining that the coding rate B meets the communication bandwidth requirements of the STA, the AP can gradually lower the default power b corresponding to the coding rate B by the set power, and The test downlink power is reduced to send measurement packets, and the measurement packets are encoded at a fixed encoding rate B. After receiving the measurement message, the STA sends a response message to the AP. When the test downlink power is adjusted to the H-th step, and the AP does not receive the STA's measurement response for the first time, it is considered that the test downlink power corresponding to the H-th step is If the downlink communication bandwidth requirement cannot be met, the test downlink power corresponding to H-1 steps can be determined as the negotiated target downlink power, where H is a positive integer greater than 1. After determining the target downlink power, the AP notifies the STA of the completion of the downlink power negotiation and synchronously informs the STA of the determined target downlink power. The STA completes the entire downlink power negotiation process after responding to the AP.

Referring to Figure 4 and Figure 6, uplink power negotiation is to negotiate the appropriate transmit power of the STA and is initiated by the STA. Among them, the STA can send measurement packets to the AP at the default power m corresponding to the maximum coding rate M. If the transmission fails, that is, no response packet from the AP is received, the coding rate is reduced, and the coding rate corresponding to the reduced coding rate N is used. The default power n sends measurement packets to the AP until a response packet is received from the AP. If the AP's response packet can be received at the default power m corresponding to the maximum coding rate M, the default power m corresponding to the maximum coding rate M can be received. Power m carries out the subsequent uplink power negotiation process. Here, the maximum coding rate M is greater than the coding rate N, and the default power m is smaller than the default power n. In addition, after receiving the response message sent by the AP, the STA can evaluate whether the successfully sent uplink coding rate meets the uplink communication bandwidth requirements. If not, the STA stops uplink power negotiation and transmits to the AP with the STA's maximum transmit power. data. If satisfied, the uplink power negotiation continues with the default power corresponding to the coding rate.

Among them, according to the different radio frequency rate configurations in MCS, the maximum coding rate M can be the maximum transmission rate corresponding to MCS7, for example, it can be 65.0Mb/s-72.2Mb/s, and the coding rate N can be between MCS0 and MCS6, for example is 6.5Mb/s-65.0Mb/s. The default power m corresponding to the coding rate M may be 21dbm, and the default power n corresponding to the coding rate N may be 17dbm. The coding rate data and default power data here are only examples and are not intended to limit this embodiment.

Taking the uplink power negotiation flow chart shown in Figure 6 as an example, after determining that the coding rate N meets the communication bandwidth requirements of the STA, the STA can gradually lower the power n corresponding to the coding rate N by the set power. The measurement packet is sent to the AP with reduced power. The measurement packet is encoded at a fixed encoding rate N. After receiving the measurement packet, the AP sends a response packet to respond to the STA. When the test uplink power is adjusted to the K-th step and the STA does not receive the measurement response from the AP for the first time, it is considered that the test uplink power corresponding to the K-th step cannot meet the uplink communication bandwidth requirements, and the K-1 The test uplink power corresponding to the sub-step is determined as the negotiated target uplink power, where K is a positive integer greater than 1. After determining the target uplink power, the STA notifies the AP of the completion of the uplink power negotiation, and synchronously notifies the AP of the determined target uplink power.

After completing the uplink power negotiation, the AP can send data to the STA at the negotiated target downlink power; after completing the downlink power negotiation, the STA can send data to the AP at the negotiated target uplink power.

After the power negotiation is successful, the AP continues to monitor the downlink rate and the cache amount of data packets sent to this STA. Once it detects that the downlink rate cannot meet the downlink communication bandwidth requirements and/or the data cache amount continues to grow, it is considered that the environment has changed. When the STA's downlink communication bandwidth is guaranteed, the AP can immediately resume sending data to the STA at the default downlink power corresponding to the encoding rate determined by the current AP; similarly, the STA also needs to continuously monitor the uplink rate and the data packets sent to the AP. Cache amount, once it is detected that the uplink rate cannot meet the uplink communication bandwidth requirement and/or the data cache amount continues to grow, the STA can immediately resume sending data to the AP at the corresponding default uplink power at the coding rate determined by the current STA.

After the uplink power or downlink power is restored to the default power corresponding to the current coding rate, the uplink power or downlink power can be negotiated again to negotiate a new appropriate power. In addition, in order to avoid the problem of frequent changes in the environment that cause the AP or STA to frequently switch between the negotiated power and the default power, you can set a threshold for switching frequency. When the switching frequency exceeds the set threshold, the above power negotiation process should be stopped and a fixed power negotiation process should be used. Maximum power.
