Background

Currently, in the wireless communication process, the negotiation rate may be determined between the wireless communication devices according to the usage environment, such as the packet loss rate, and the actual transmission rate is determined for communication between the wireless communication devices with the negotiation rate as a guide.

In the embodiment of the present invention, in a process of the wireless communication device communicating with other communication devices, the original packet loss rate of the wireless communication device is obtained.

In the embodiment of the present invention, in the process of performing wireless communication by a wireless communication device, the original packet loss rate may be sent to the wireless communication device by a communication peer communicating with the wireless communication device, where the original packet loss rate is obtained. Specifically, in the process that the correspondent node sends the retransmission instruction to the wireless communication device, the wireless communication device obtains the original packet loss rate thereof through the retransmission instruction. The original packet loss rate may be a packet loss rate at the current time, or may also be an average packet loss rate within a period of time, and the like, which is not specifically limited in the embodiment of the present invention.

Example two

Referring to fig. 2, a flowchart of a transmission power control method provided in the second embodiment of the present invention is shown, and is applied to a wireless communication device, and for the wireless communication device, reference may be made to relevant descriptions in the embodiments of the present invention, and details are not repeated here. The method specifically comprises the following steps:

step 201, obtaining an original packet loss rate, an original negotiation rate, and an original transmission power of the wireless communication device.

In the embodiment of the present invention, step 201 may refer to the detailed description of step 101 in the first embodiment of the present invention, and is not described herein again.

Step 202, the preset packet loss rate includes: a high-quality packet loss rate threshold; and if the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, reducing the original transmitting power according to a first preset step length to obtain a second target transmitting power.

In this embodiment of the present invention, the preset packet loss ratio includes: a high-quality packet loss rate threshold, where the high-quality packet loss rate threshold may be a packet loss rate corresponding to the wireless communication device when the packet loss rate is smaller, for example, the high-quality packet loss rate threshold may be a packet loss rate of 3%.

In the embodiment of the present invention, the preset negotiation rate may be a larger negotiation rate that the wireless communication device can reach. That is, the preset negotiated rate may be a negotiated rate corresponding to the wireless communication device with better throughput. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, if the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and is greater than 0, it indicates that the current packet loss rate of the wireless communication device is low. The original negotiation rate is greater than or equal to the preset negotiation rate, and since the preset negotiation rate can be a larger negotiation rate that the wireless communication device can reach, it indicates that the negotiation rate of the wireless communication device has reached a higher rate, that is, the transmission rate of the wireless communication device is higher.

In the embodiment of the present invention, if the original packet loss rate is less than or equal to the high quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, in this case, the communication performance of the wireless communication device is better, the promotion space of the communication performance is already particularly small, and the original transmission power of the wireless communication device can be reduced according to the first preset step length to obtain the second target transmission power.

In the embodiment of the present invention, the first preset step may be set according to an actual communication requirement, and specifically, the first preset step may be set in combination with an actual communication experience and an actual communication requirement.

For example, if the high-quality packet loss rate threshold is 3%, the preset negotiation rate is 5M/s, if the original packet loss rate is 2%, the original negotiation rate is 6M/s, the original transmission power is 3dBm, and the first preset step length is 0.5dBm, then the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, then the communication performance of the wireless communication device is better, the promotion space of the communication performance is particularly small, the original transmission power of the wireless communication device is reduced according to the first preset step length of 0.5dBm, and the obtained second target transmission power is 2.5 dBm.

Step 203, determining whether the second target transmission power is less than or equal to the minimum transmission power of the wireless communication device.

In this embodiment of the present invention, after the wireless communication device determines, the minimum transmission power of the wireless communication device is determined, that is, the minimum transmission power of the wireless communication device may be an attribute of the wireless communication device itself, which is not particularly limited in this embodiment of the present invention.

In the embodiment of the invention, whether the second target transmission power is less than or equal to the minimum transmission power of the wireless communication equipment is judged. To ensure that the wireless communication device is operating properly, the wireless communication device is not operating below its minimum transmit power.

And 204, if yes, determining the minimum transmitting power as the first target transmitting power.

In the implementation of the present invention, if the second target transmission power is less than or equal to the minimum transmission power of the wireless communication device, in order to ensure that the wireless communication device can operate normally and to save power consumption, the minimum transmission power of the wireless communication device may be determined as the first target transmission power of the wireless communication device.

For example, for the above example, if the second target transmission power is 2.5dBm, and if the minimum transmission power of the wireless communication device is 2.6dBm, the second target transmission power is smaller than the minimum transmission power of the wireless communication device, and in order to ensure that the wireless communication device can operate normally, the first target transmission power of the wireless communication device may be determined as the minimum transmission power of the wireless communication device of 2.6 dBm.

Step 205, if not, determining the first target transmission power according to the corresponding first packet loss ratio and the high quality packet loss ratio threshold, and the corresponding first negotiation rate and the preset negotiation rate of the wireless communication device under the second target transmission power.

In this embodiment of the present invention, if the second target transmission power is greater than the minimum transmission power of the wireless communication device, the first target transmission power is determined according to a corresponding first packet loss rate and a high quality packet loss rate threshold, and a corresponding first negotiation rate and a preset negotiation rate of the wireless communication device under the condition of the second target transmission power.

For example, if the high-quality packet loss rate threshold is 3%, the preset negotiation rate is 5M/s, if the original packet loss rate is 2%, the original negotiation rate is 6M/s, the original transmission power is 5dBm, and the first preset step length is 0.5dBm, then the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, then the communication performance of the wireless communication device is better, the promotion space of the communication performance is particularly small, the original transmission power of the wireless communication device is reduced according to the first preset step length of 0.5dBm, and the obtained second target transmission power is 4.5 dBm. And if the minimum transmitting power of the wireless communication equipment is 2.6dBm, the second target transmitting power is larger than the minimum transmitting power of the wireless communication equipment, and the first target transmitting power is determined according to the corresponding first packet loss rate and high-quality packet loss rate threshold value, the corresponding first negotiation rate and the preset negotiation rate of the wireless communication equipment under the condition of the second target transmitting power.

Specifically, fig. 3 shows a flowchart for determining a first target transmission power according to a second target transmission power, where the step of determining the first target transmission power according to a corresponding first packet loss ratio and the high quality packet loss ratio threshold, and a corresponding first negotiation rate and the preset negotiation rate of the wireless communication device under the condition of the second target transmission power may include:

in sub-step 2051, if the first packet loss ratio is less than or equal to the high quality packet loss ratio threshold and the first negotiation rate is greater than or equal to the preset negotiation rate, replacing the original transmission power with the second target transmission power, and continuing to perform the step of reducing the original transmission power according to a first preset step length to obtain a second target transmission power.

In sub-step 2052, if the first packet loss ratio is greater than the high quality packet loss ratio threshold, or the first negotiation rate is smaller than the preset negotiation rate, the second target transmission power is increased by the first preset step length to obtain the first target transmission power.

In the embodiment of the present invention, a corresponding first packet loss rate and a corresponding first negotiation rate of the wireless communication device under the condition of the second target transmission power are obtained. Specifically, the current packet loss rate and the negotiation rate of the wireless communication device may be obtained by obtaining a corresponding first packet loss rate and a corresponding first negotiation rate of the wireless communication device under the condition of the second target transmission power, or temporarily adjusting the current transmission power of the wireless communication device to the second target transmission power, determining the packet loss rate as the first packet loss rate, and determining the negotiation rate as the first negotiation rate.

In this embodiment of the present invention, if the second target transmission power is greater than the minimum transmission power of the wireless communication device, and if the wireless communication device is in the second target transmission power, the corresponding first packet loss rate and the threshold of the high quality packet loss rate are less than or equal to, and the corresponding first negotiation rate and the preset negotiation rate are greater than or equal to, which indicate that the communication performance of the wireless communication device is still better in the second target transmission power, the original transmission power is replaced with the second target transmission power, and the step of reducing the original transmission power according to the first preset step length is continuously performed to obtain the second target transmission power.

For example, if the high-quality packet loss rate threshold is 3%, the preset negotiation rate is 5M/s, if the original packet loss rate is 2%, the original negotiation rate is 6M/s, the original transmission power is 5dBm, and the first preset step length is 0.5dBm, then the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, then the communication performance of the wireless communication device is better, the promotion space of the communication performance is particularly small, the original transmission power of the wireless communication device is reduced according to the first preset step length of 0.5dBm, and the obtained second target transmission power is 4.5 dBm. If the minimum transmitting power of the wireless communication device is 2.6dBm, the second target transmitting power is greater than the minimum transmitting power of the wireless communication device, under the condition of the second target transmitting power, the corresponding first packet loss rate is 2.3%, and the corresponding first negotiation rate is 5.4M/s, it is indicated that the communication performance of the wireless communication device is still better under the condition of the second target transmitting power, the original transmitting power is replaced by the second target transmitting power of 4.5dBm, the step of reducing the original transmitting power according to the first preset step length of 0.5dBm is continuously executed, the step of obtaining the second target transmitting power is obtained, the reduced original transmitting power is continuously compared with the minimum transmitting power of the wireless device, and the like.

In the embodiment of the present invention, if the first packet loss rate is greater than the high-quality packet loss rate threshold or the first negotiation rate is smaller than the preset negotiation rate under the condition that the wireless communication device is at the second target transmission power, which indicates that the communication performance of the wireless communication device is not good or the communication requirement is not met under the condition that the wireless communication device is at the second target transmission power, the second target transmission power may be increased by the first preset step length to obtain the first target transmission power.

For example, if the high-quality packet loss rate threshold is 3%, the preset negotiation rate is 5M/s, if the original packet loss rate is 2%, the original negotiation rate is 6M/s, the original transmission power is 5dBm, and the first preset step length is 0.5dBm, then the original packet loss rate is less than or equal to the high-quality packet loss rate threshold and greater than 0, and the original negotiation rate is greater than or equal to the preset negotiation rate, then the communication performance of the wireless communication device is better, the promotion space of the communication performance is particularly small, the original transmission power of the wireless communication device is reduced according to the first preset step length of 0.5dBm, and the obtained second target transmission power is 4.5 dBm. If the minimum transmitting power of the wireless communication device is 2.6dBm, the second target transmitting power is greater than the minimum transmitting power of the wireless communication device, the corresponding first packet loss rate of the wireless communication device is 3.3% under the condition of the second target transmitting power, the corresponding first negotiation rate is 5.4M/s, and the corresponding first packet loss rate of the wireless communication device is greater than the high-quality packet loss rate threshold under the condition of the second target transmitting power, which indicates that the communication performance of the wireless communication device is not good under the condition of the second target transmitting power or the actual communication requirement cannot be met, and the second target transmitting power is 4.5dBm, and the first preset step length is increased by 0.5dBm, so that the first target transmitting power is 5 dBm. Thereby ensuring the communication performance of the wireless communication device.

For another example, for the above example, if the original transmission power is replaced by the second target transmission power of 4.5dBm, the original transmission power is reduced according to the first preset step size of 0.5dBm, and the second target transmission power of 4dBm is obtained, the second target transmission power of 4dBm is greater than the minimum transmission power of the wireless communication device of 2.6dBm, if the wireless communication device has a corresponding first packet loss rate of 2.7% and a corresponding first negotiation rate of 4.4M/s under the condition of the second target transmission power, and the corresponding first negotiation rate of 4dBm is less than the preset negotiation rate under the condition of the second target transmission power, which indicates that the communication performance of the wireless communication device is not good under the condition of the second target transmission power, or the actual communication requirement is not met, the second target transmission power of 4dBm may be increased by the first preset step size of 0.5dBm, the first target transmit power of 4.5dBm is obtained. Thereby ensuring the communication performance of the wireless communication device.

For another example, if the second target transmission power is 2.9dBm, if the original transmission power is 3.4dBm replaced by the second target transmission power of 2.9dBm, the original transmission power is reduced according to the first preset step size of 0.5dBm, and the second target transmission power of 2.4dBm is obtained, and the second target transmission power of 2.6dBm is smaller than the minimum transmission power of the wireless communication device, then in order to ensure the normal operation of the wireless communication device, the minimum transmission power of 2.6dBm of the wireless communication device may be determined as the first target transmission power.

In the embodiment of the present invention, if the second target transmission power is greater than the minimum transmission power of the wireless communication device, and the wireless communication device is under the second target transmission power, if the corresponding first packet loss rate is less than or equal to the high quality packet loss rate threshold and the corresponding first negotiation rate is greater than or equal to the preset negotiation rate, it indicates that the communication performance of the wireless communication device is better under the second target transmission power, in order to save the transmission power, the second target transmission power may be further reduced, and if the wireless communication device is under the reduced second target transmission power, the corresponding first packet loss rate is greater than the high quality packet loss rate threshold or the corresponding first negotiation rate is less than the preset negotiation rate, it indicates that the communication performance of the wireless communication device is not very good under the second target transmission power, or the actual communication requirement is not met, in order to ensure the communication performance of the wireless communication device, the first preset step size may be added to the second target transmission power to obtain the first target transmission power. Namely, in the embodiment of the invention, dynamic compromise is performed in power consumption saving and communication performance guarantee, so that the effects of saving power consumption and guaranteeing communication performance are achieved.

Step 206, if the original packet loss rate is equal to 0 and the original negotiation rate is smaller than the preset negotiation rate, gradually increasing the original negotiation rate according to a second preset step length until the corresponding second packet loss rate is greater than the high-quality packet loss rate threshold under the conditions of the original transmission power and the increased original negotiation rate of the wireless communication device, so as to obtain a second negotiation rate.

In the embodiment of the present invention, if the original packet loss rate is equal to 0, that is, the packet loss rate has already reached the optimum, and if the packet loss rate reaches the optimum and the original negotiation rate is smaller than the preset negotiation rate, which indicates that the negotiation rate of the wireless communication device has not reached a better rate, the original negotiation rate of the wireless communication device may be gradually increased according to a second preset step size until the corresponding second packet loss rate of the wireless communication device is greater than the threshold of the good-quality packet loss rate under the conditions of the original transmission power and the increased original negotiation rate, so as to obtain the second negotiation rate.

In the embodiment of the present invention, the second preset step size may be set according to experience and actual communication requirements, which is not particularly limited in the embodiment of the present invention.

For example, if the original packet loss rate is 0, the original transmission power is 3.2dBm, the original negotiation rate is 4.2M/s, the preset negotiation rate is 5M/s, the original negotiation rate is 4.2M/s and is less than the preset negotiation rate by 5M/s, and the second preset step length is 0.4M/s, the original negotiation rate of the wireless communication device may be gradually increased until the corresponding second packet loss rate of the wireless communication device is greater than the high-quality packet loss rate threshold value under the conditions of the original transmission power and the increased original negotiation rate, so as to obtain the second negotiation rate, and if the second negotiation rate is 5M/s, the corresponding second packet loss rate of the wireless communication device is greater than the high-quality packet loss rate threshold value by 3.5% under the conditions of the original transmission power by 3.2dBm and the second negotiation rate by 5M/s.

Step 207, decreasing the second negotiation rate by the second preset step size, and determining the second negotiation rate after decreasing the second preset step size as the first target negotiation rate of the wireless communication device.

In the embodiment of the present invention, under the conditions of the original transmission power and the increased second negotiation rate, the corresponding second packet loss rate is greater than the high quality packet loss rate threshold, which indicates that under such a condition, the packet loss rate of the wireless communication device does not meet the communication requirement, the second negotiation rate may be decreased by a second preset step length, and the second negotiation rate after the second preset step length is decreased is determined as the first target negotiation rate of the wireless communication device.

In this embodiment of the present invention, the first target negotiation rate of the wireless communication device may be a negotiation rate of the wireless communication device at the next time, or the first target negotiation rate of the wireless communication device may be a negotiation rate of the wireless communication device in a future time period, which is not specifically limited in this embodiment of the present invention.

For example, for the above example, if the original packet loss rate is 0, the original transmission power is 3.2dBm, the original negotiation rate is 4.2M/s, the preset negotiation rate is 5M/s, the original negotiation rate is 4.2M/s and is less than the preset negotiation rate by 5M/s, and the second preset step size is 0.4M/s, the original negotiation rate of the wireless communication device may be gradually increased, if the wireless communication device has the original transmission power of 3.2dBm and the second negotiation rate is 5M/s, and the corresponding second packet loss rate of 3.5% is greater than the high-quality packet loss rate threshold value by 3%, the second negotiation rate of 5M/s is decreased by 0.4M/s, and the second negotiation rate after the second step size is decreased by 4.6M/s is determined as the first target negotiation rate of the wireless communication device.

Step 208, determining the original transmission power as the first target transmission power.

In this embodiment of the present invention, the original transmission power may be determined as the first target transmission power of the wireless communication device, which is not particularly limited in this embodiment of the present invention.

For example, for the above example, if the original packet loss rate is 0, the original transmission power is 3.2dBm, the original negotiation rate is 4.2M/s, the preset negotiation rate is 5M/s, the original negotiation rate is 4.2M/s and is less than the preset negotiation rate by 5M/s, and the second preset step size is 0.4M/s, the original negotiation rate of the wireless communication device may be gradually increased, if the wireless communication device has the original transmission power of 3.2dBm and the second negotiation rate is 5M/s, and the corresponding second packet loss rate of 3.5% is greater than the high-quality packet loss rate threshold value by 3%, the second negotiation rate of 5M/s is decreased by 0.4M/s, and the second negotiation rate after the second step size is decreased by 4.6M/s is determined as the first target negotiation rate of the wireless communication device. The original transmit power was 3.2dBm, determined as the first target transmit power.

In the embodiment of the present invention, if the original packet loss rate is equal to 0 and the original negotiation rate is less than the preset negotiation rate, the original negotiation rate of the wireless communication device is gradually increased according to a second preset step size until the corresponding second packet loss rate is greater than the high-quality packet loss rate threshold under the conditions of the original transmission power and the increased original negotiation rate of the wireless communication device, so as to obtain a second negotiation rate, the second negotiation rate is decreased by the second preset step size, and the second negotiation rate after the second preset step size is decreased is determined as the first target negotiation rate of the wireless communication device, that is, the negotiation rate is optimized under the condition that the packet loss rate does not have an optimized space, so as to improve the transmission power and improve the throughput.

Step 209, the preset packet loss rate further includes: a threshold value of the poor packet loss rate; the poor packet loss rate threshold is greater than the high-quality packet loss rate threshold; and if the original packet loss rate is greater than the high-quality packet loss rate threshold and less than or equal to the poor-quality packet loss rate threshold, increasing the original transmitting power according to a third preset step length to obtain a third target transmitting power.

In this embodiment of the present invention, the preset packet loss ratio includes: the poor packet loss rate threshold may be a packet loss rate corresponding to the wireless communication device when the packet loss rate is relatively high, for example, the poor packet loss rate threshold may be a packet loss rate of 30%.

In the embodiment of the present invention, the threshold of the poor packet loss rate is greater than the threshold of the high quality packet loss rate, for example, for the above example, the threshold of the high quality packet loss rate is 3%, and the threshold of the poor packet loss rate may be 30%. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, if the original packet loss rate is greater than the threshold of the poor packet loss rate, it indicates that the current packet loss rate of the wireless communication device is greater. The original packet loss rate cannot meet the current communication requirement, and needs to be optimized.

In the embodiment of the present invention, if the original packet loss rate is greater than the threshold of the poor packet loss rate, in this case, the original packet loss rate of the wireless communication device is poor and needs to be optimized, and the original transmission power of the wireless communication device may be increased according to a third preset step length to obtain a third target transmission power.

In the embodiment of the present invention, the third preset step may be set according to an actual communication requirement, and specifically, may be set in combination with an actual communication experience and an actual communication requirement, which is not specifically limited in the embodiment of the present invention.

For example, if the threshold of the poor packet loss rate is 30%, if the high-quality packet loss rate is 3%, if the original packet loss rate is 25%, the original negotiation rate is 6M/s, the original transmission power is 3dBm, and the third preset step size is 0.3dBm, then the original packet loss rate is greater than 25% of the high-quality packet loss rate by 3%, and is less than 30% of the threshold of the poor packet loss rate, the original packet loss rate of the wireless communication device is poor, optimization is required, the original transmission power of the wireless communication device is increased according to the third preset step size of 0.3dBm, and the obtained third target transmission power is 3.3 dBm.

Step 210, determining whether the third target transmission power is greater than or equal to the maximum transmission power of the wireless communication device.

In this embodiment of the present invention, after the wireless communication device determines, the maximum transmission power of the wireless communication device is determined, that is, the maximum transmission power of the wireless communication device may be an attribute of the wireless communication device itself, which is not specifically limited in this embodiment of the present invention.

In the embodiment of the present invention, it is determined whether the third target transmission power is greater than or equal to the maximum transmission power of the wireless communication device. To ensure that the wireless communication device is operating properly, the wireless communication device is not operating above its maximum transmit power.

Step 211, if the third target transmission power is greater than or equal to the maximum transmission power, determining the maximum transmission power as the first target transmission power, and determining whether a third packet loss rate corresponding to the wireless communication device is less than or equal to the high quality packet loss rate threshold under the condition of the maximum transmission power and the original negotiation rate.

In the implementation of the present invention, if the third target transmission power is greater than or equal to the maximum transmission power of the wireless communication device, in order to ensure that the wireless communication device can operate normally, the maximum transmission power of the wireless communication device may be determined as the first target transmission power of the wireless communication device. And meanwhile, judging whether the corresponding third packet loss rate is less than or equal to the high-quality packet loss rate threshold value or not under the conditions of the maximum transmitting power and the original negotiation rate of the wireless communication equipment.

For example, if the third target transmission power is 8dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is greater than the maximum transmission power of the wireless communication device, and in order to ensure that the wireless communication device can operate normally, the maximum transmission power of the wireless communication device of 7dBm may be determined as the first target transmission power of the wireless communication device. If the wireless communication device is under the conditions of the maximum transmitting power of 7dBm and the original negotiation rate of 3M/s, the corresponding third packet loss rate is 4%.

Step 212, if the third packet loss rate is greater than the high quality packet loss rate threshold, gradually decreasing the original negotiation rate according to a fourth preset step length until the corresponding fourth packet loss rate is less than or equal to the high quality packet loss rate threshold under the condition that the wireless communication device is at the maximum transmission power and the decreased original negotiation rate, so as to obtain a third negotiation rate.

In the embodiment of the present invention, if the third packet loss rate corresponding to the wireless communication device is greater than the high quality packet loss rate threshold under the conditions of the maximum transmission power and the original negotiation rate, which indicates that the communication requirement of the packet loss rate still cannot be met under the condition that the transmission power has been increased to the maximum, in order to preferentially ensure the packet loss rate, the original negotiation rate may be gradually reduced according to a fourth preset step size until the fourth packet loss rate corresponding to the wireless communication device is less than or equal to the high quality packet loss rate threshold under the conditions of the maximum transmission power and the reduced original negotiation rate, so as to obtain the third negotiation rate.

In the embodiment of the present invention, the fourth preset step may be set according to an actual communication requirement, and specifically, may be set in combination with an actual communication experience and an actual communication requirement, which is not specifically limited in the embodiment of the present invention.

For example, if the third target transmission power is 8dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is greater than the maximum transmission power of the wireless communication device, and in order to ensure that the wireless communication device can operate normally, the maximum transmission power of the wireless communication device of 7dBm may be determined as the first target transmission power of the wireless communication device. If the wireless communication device has a corresponding third packet loss rate of 4% under the conditions of a maximum transmission power of 7dBm and an original negotiation rate of 3M/s, and if the high-quality packet loss rate threshold is 3%, the wireless communication device has a corresponding third packet loss rate greater than the high-quality packet loss rate threshold under the conditions of a maximum transmission power of 7dBm and an original negotiation rate of 3M/s, which indicates that the communication requirement of the packet loss rate cannot be met even when the transmission power is increased to the maximum, in order to preferentially ensure the packet loss rate, if the fourth preset step size is 0.2M/s, the original negotiation rate of 3M/s can be gradually reduced according to the fourth preset step size until 2.8% of the corresponding fourth packet loss rate is less than or equal to the high-quality packet loss rate threshold of 3% under the conditions of a maximum transmission power of 7dBm and a reduced original negotiation rate of 2M/s, a third negotiation rate of 2M/s is obtained.

Step 213, determining the third negotiated rate as the first target negotiated rate for the wireless communication device.

In the embodiment of the present invention, when the maximum transmission power and the reduced original negotiation rate are the same, the corresponding fourth packet loss rate is less than or equal to the high quality packet loss rate threshold, which indicates that the packet loss rate meets the communication quality requirement in this case, and then the third negotiation rate is determined as the first target negotiation rate of the wireless communication device.

For example, if the third target transmission power is 8dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is greater than the maximum transmission power of the wireless communication device, and in order to ensure that the wireless communication device can operate normally, the maximum transmission power of the wireless communication device of 7dBm may be determined as the first target transmission power of the wireless communication device. If the wireless communication device has a corresponding third packet loss rate of 4% under the conditions of a maximum transmission power of 7dBm and an original negotiation rate of 3M/s, and if the high-quality packet loss rate threshold is 3%, the wireless communication device has a corresponding third packet loss rate greater than the high-quality packet loss rate threshold under the conditions of a maximum transmission power of 7dBm and an original negotiation rate of 3M/s, which indicates that the communication requirement of the packet loss rate cannot be met even when the transmission power is increased to the maximum, in order to preferentially ensure the packet loss rate, if the fourth preset step size is 0.2M/s, the original negotiation rate of 3M/s can be gradually reduced according to the fourth preset step size until 2.8% of the corresponding fourth packet loss rate is less than or equal to the high-quality packet loss rate threshold of 3% under the conditions of a maximum transmission power of 7dBm and a reduced original negotiation rate of 2M/s, a third negotiation rate of 2M/s is obtained. In this case, if the packet loss rate meets the communication quality requirement, the third negotiation rate 2M/s is determined as the first target negotiation rate of the wireless communication device.

Step 214, if the third target transmission power is smaller than the maximum transmission power, determining the first target transmission power according to a fifth packet loss rate and the high quality packet loss rate threshold corresponding to the wireless communication device under the conditions of the third target transmission power and the original negotiated rate.

In the embodiment of the present invention, if the third target transmission power is smaller than the maximum transmission power, the first target transmission power is determined according to a fifth packet loss rate and a high quality packet loss rate threshold corresponding to the wireless communication device under the conditions of the third target transmission power and the original negotiated rate.

Specifically, fig. 4 shows a flowchart for determining a first target transmission power according to a third target transmission power, where the step of determining the first target transmission power according to a fifth packet loss ratio and the high quality packet loss ratio threshold, which correspond to the wireless communication device, under the third target transmission power and the original negotiated rate, may include:

substep 2141, if the fifth packet loss rate is greater than the high quality packet loss rate threshold, replacing the original transmission power with the third target transmission power, and continuing to perform the step of increasing the original transmission power according to a third preset step length to obtain a third target transmission power.

Substep 2142, if the fifth packet loss rate is less than or equal to the high quality packet loss rate threshold, determining the third target transmission power as the first target transmission power.

In the embodiment of the present invention, if the third target transmission power is less than the maximum transmission power, and if the corresponding fifth packet loss rate is greater than the high-quality packet loss rate threshold under the conditions of the third target transmission power and the original negotiated rate, which indicates that the packet loss rate still does not meet the communication quality requirement under the conditions, the third target transmission power is used to replace the original transmission power, and the step of increasing the original transmission power according to a third preset step length to obtain the third target transmission power is continuously performed.

For example, if the third target transmission power is 5dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is less than the maximum transmission power of the wireless communication device, if the wireless communication device has a corresponding fifth packet loss rate of 4% and is greater than the high-quality packet loss rate threshold value by 3% under the condition that the third target transmission power is 5dBm and the original negotiation rate is 3M/s, replacing the original transmission power by the third target transmission power of 5dBm, continuing to perform the step of increasing the original transmission power according to a third preset step size of 0.3dBm to obtain the third target transmission power of 5.3dBm, and similarly, continuing to perform the step of judging whether the third target transmission power is greater than or equal to the maximum transmission power of the wireless communication device.

In this embodiment of the present invention, if the fifth packet loss rate is less than or equal to the high quality packet loss rate threshold, which indicates that the communication quality requirement is satisfied under this condition, the third target transmission power is determined as the first target transmission power.

For example, if the third target transmission power is 5dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is smaller than the maximum transmission power of the wireless communication device, and if the wireless communication device meets the communication quality requirement under the condition that the third target transmission power is 5dBm and the original negotiated rate is 3M/s, the corresponding fifth packet loss rate is 2.9% and is smaller than the high-quality packet loss rate threshold value by 3%, which indicates that the third target transmission power of 5dBm is the first target transmission power.

For another example, if the third target transmission power is 5dBm, if the maximum transmission power of the wireless communication device is 7dBm, the third target transmission power is less than the maximum transmission power of the wireless communication device, if the wireless communication device has a corresponding fifth packet loss rate of 4% and greater than the high-quality packet loss rate threshold of 3% under the condition of 5dBm of the third target transmission power and 3M/s of the original negotiation rate, replacing 4.7dBm of the original transmission power with 5dBm of the third target transmission power, continuing to execute increasing the original transmission power according to a third preset step size of 0.3dBm to obtain 5.3dBm of the third target transmission power, where 5.3dBm of the third target transmission power is less than 7dBm of the maximum transmission power of the wireless communication device, and if the wireless communication device has 5.3dBm of the third target transmission power and 3M/s of the original negotiation rate, the corresponding fifth packet loss rate of 2.6%, and determining the third target transmitting power of 5.3dBm as the first target transmitting power when the packet loss rate is less than or equal to 3 percent of the high-quality packet loss rate threshold.

In this embodiment of the present invention, the step of determining the first target transmission power of the wireless communication device according to the original packet loss ratio and the preset packet loss ratio, the original negotiation rate and the preset negotiation rate, and the original transmission power may further include: if the original packet loss rate is greater than the poor packet loss rate threshold, increasing the original transmitting power according to a fifth preset step length, and decreasing the original negotiation rate according to a sixth preset step length to obtain a fourth target transmitting power and a fourth negotiation rate.

In the embodiment of the present invention, if the original packet loss rate is greater than the threshold of the poor packet loss rate, which indicates that the packet loss rate is particularly poor under such a situation and needs to be adjusted as soon as possible, the original transmission power is increased according to the fifth preset step length, and the original negotiation rate is decreased according to the sixth preset step length, so as to obtain the fourth target transmission power and the fourth negotiation rate. That is, when the packet loss rate is particularly poor, in order to adjust the packet loss rate as soon as possible, the transmission power is increased, and the negotiation rate needs to be decreased at the same time, so as to achieve the purpose of improving the packet loss rate as soon as possible.

In the embodiment of the present invention, the fifth preset step length and the sixth preset step length may be set according to actual communication needs, and may specifically be set in combination with actual communication experiences and actual communication needs.

For example, if the original packet loss rate is 40% and the threshold of the poor packet loss rate is 30%, the original packet loss rate is 40% greater than the threshold of the poor packet loss rate by 30%, which indicates that the packet loss rate is particularly poor under such a situation, in order to adjust the packet loss rate as soon as possible, the original transmission power is increased by 5dBm according to a fifth preset step size of 0.7dBm, and the original negotiation rate is decreased by 3M/s according to a sixth preset step size of 0.8M/s, so as to obtain a fourth target transmission power of 5.7dBm and a fourth negotiation rate of 2.2M/s.

In the embodiment of the present invention, the method may further include: and judging whether the fourth target transmitting power is larger than or equal to the maximum transmitting power.

In the embodiment of the present invention, in order to ensure that the wireless communication device can operate normally, it is necessary to determine whether the fourth target transmission power is greater than or equal to the maximum transmission power of the wireless communication device.

For example, with respect to the above example, it is determined whether the fourth target transmission power is 5.7dBm, which is equal to or greater than the maximum transmission power of the wireless communication device, which is 7 dBm.

In the embodiment of the present invention, the method may further include: if the fourth target transmission power is greater than or equal to the maximum transmission power, determining the maximum transmission power as the first target transmission power, and determining whether a corresponding fifth packet loss rate of the wireless communication device is less than or equal to the high-quality packet loss rate threshold under the conditions of the maximum transmission power and the fourth negotiation rate.

In the embodiment of the present invention, if the fourth target transmission power is greater than or equal to the maximum transmission power, the maximum transmission power is determined as the first target transmission power, and it is determined whether the corresponding fifth packet loss rate is less than or equal to the high quality packet loss rate threshold under the condition that the wireless communication device has the maximum transmission power and the fourth negotiation rate.

For example, if the original packet loss rate is 35% and the threshold of the poor packet loss rate is 30%, the original packet loss rate is 35% greater than the threshold of the poor packet loss rate by 30%, which indicates that the packet loss rate is particularly poor under such a situation, in order to adjust the packet loss rate as soon as possible, the original transmission power is increased by 6.5dBm according to a fifth preset step size of 0.7dBm, and the original negotiation rate is decreased by 4M/s according to a sixth preset step size of 0.8M/s, so as to obtain a fourth target transmission power of 7.2dBm and a fourth negotiation rate of 3.2M/s. If the maximum transmitting power of the wireless communication device is 7dBm, the fourth target transmitting power 7.2dBm is greater than the maximum transmitting power of the wireless communication device, 7dBm is determined as the first target transmitting power, and whether the corresponding fifth packet loss rate 2.7% is less than or equal to the high-quality packet loss rate threshold value is judged under the condition that the maximum transmitting power of the wireless communication device is 7dBm and the fourth negotiation rate is 3.2M/s.

In the embodiment of the present invention, the method may further include: if the corresponding fifth packet loss rate of the wireless communication device is greater than the high-quality packet loss rate threshold under the conditions of the maximum transmission power and the fourth negotiation rate, replacing the original negotiation rate with the fourth negotiation rate, and gradually reducing the original negotiation rate according to the sixth preset step length until the corresponding sixth packet loss rate of the wireless communication device is less than or equal to the high-quality packet loss rate threshold under the conditions of the maximum transmission power and the reduced original negotiation rate, so as to obtain a fifth negotiation rate.

In the embodiment of the present invention, if the corresponding fifth packet loss rate is greater than the high-quality packet loss rate threshold value under the conditions of the maximum transmission power and the fourth negotiation rate of the wireless communication device, which indicates that the packet loss rate still does not meet the communication quality requirement under such conditions, the fourth negotiation rate is used to replace the original negotiation rate, and the original negotiation rate is gradually reduced according to a sixth preset step length until the corresponding sixth packet loss rate is less than or equal to the high-quality packet loss rate threshold value under the conditions of the maximum transmission power and the reduced original negotiation rate of the wireless communication device, so as to obtain the fifth negotiation rate.

In the embodiment of the present invention, the sixth preset step may be set according to actual communication needs, specifically, may be set by combining actual communication experience and actual communication needs, and this is not particularly limited in the embodiment of the present invention.

For example, if the original packet loss rate is 45% and the threshold of the poor packet loss rate is 30%, the original packet loss rate is 45% greater than the threshold of the poor packet loss rate by 30%, which indicates that the packet loss rate is particularly poor under such a situation, in order to adjust the packet loss rate as soon as possible, the original transmission power is increased by 6.5dBm according to a fifth preset step size of 0.7dBm, and the original negotiation rate is decreased by 5M/s according to a sixth preset step size of 0.8M/s, so as to obtain a fourth target transmission power of 7.2dBm and a fourth negotiation rate of 4.2M/s. If the maximum transmitting power of the wireless communication device is 7dBm, the fourth target transmitting power 7.2dBm is greater than the maximum transmitting power of the wireless communication device of 7dBm, the maximum transmitting power of 7dBm is determined as the first target transmitting power, and if the wireless communication device is at the maximum transmitting power of 7dBm and the fourth negotiation rate of 4.2M/s, the corresponding fifth packet loss rate of 3.3% is greater than the threshold of the high quality packet loss rate of 3%. And if the packet loss rate still does not meet the communication quality requirement under the condition, replacing the original negotiation rate by the fourth negotiation rate of 4.2M/s for 5M/s, and gradually reducing the original negotiation rate of 4.2M/s according to a sixth preset step length of 1M/s until the corresponding sixth packet loss rate is less than or equal to a high-quality packet loss rate threshold value under the conditions that the maximum transmission power of the wireless communication equipment is 7dBm and the reduced original negotiation rate is 3.2M/s, so as to obtain a fifth negotiation rate of 3.2M/s.

In the embodiment of the present invention, the method may further include: if the corresponding fifth packet loss rate is less than or equal to the high-quality packet loss rate threshold value under the conditions of the maximum transmission power and the fourth negotiation rate of the wireless communication device, determining the maximum transmission power as the first target transmission power, and determining the fourth negotiation rate as the first target negotiation rate of the wireless communication device.

In the embodiment of the present invention, if the wireless communication device has the maximum transmission power and the fourth negotiation rate, and the corresponding fifth packet loss rate is less than or equal to the high quality packet loss rate threshold, and the packet loss rate already meets the communication quality requirement, the maximum transmission power is determined as the first target transmission power, and the fourth negotiation rate is determined as the first target negotiation rate of the wireless communication device.

In the embodiment of the present invention, the method may further include: determining the fifth negotiated rate as the first target negotiated rate for the wireless communication device.

In an embodiment of the present invention, the fifth negotiated rate is determined to be the first target negotiated rate for the wireless communication device. For example, for the above example, then the fifth negotiated rate of 3.2M/s is determined to be the first target negotiated rate for the wireless communication device.

In the embodiment of the present invention, the method may further include: if the fourth target transmission power is less than the maximum transmission power, determining the first target transmission power according to a seventh packet loss rate and the bad packet loss rate threshold corresponding to the wireless communication device under the conditions of the fourth target transmission power and the fourth negotiation rate.

In the embodiment of the present invention, if the fourth target transmission power is less than the maximum transmission power, the first target transmission power is determined according to a seventh packet loss rate and an inferior packet loss rate threshold corresponding to the fourth target transmission power and the fourth negotiation rate of the wireless communication device.

Specifically, the step of determining the first target transmission power according to a seventh packet loss ratio and the bad packet loss ratio threshold corresponding to the fourth target transmission power and the fourth negotiation rate of the wireless communication device may include: if the seventh packet loss rate is greater than the threshold of the poor packet loss rate, replacing the original transmitting power with the fourth target transmitting power, replacing the original negotiation rate with the fourth negotiation rate, continuing to execute the steps of increasing the original transmitting power according to a fifth preset step length, and reducing the original negotiation rate according to a sixth preset step length to obtain a fourth target transmitting power and a fourth negotiation rate; if the seventh packet loss rate is less than or equal to the poor packet loss rate threshold, replacing the original packet loss rate with the seventh packet loss rate, replacing the original negotiation rate with the fourth negotiation rate, and determining the first target transmission power according to the size relationship between the replaced original packet loss rate and 0, the high-quality packet loss rate threshold and the poor-quality packet loss rate threshold, and the size relationship between the replaced original negotiation rate and the preset negotiation rate.

Specifically, for example, if the original packet loss rate is 42% and the threshold of the poor packet loss rate is 30%, the original packet loss rate is 42% greater than the threshold of the poor packet loss rate by 30%, which indicates that the packet loss rate is particularly poor under such a situation, in order to adjust the packet loss rate as soon as possible, the original transmission power is increased by 4.1dBm according to a fifth preset step size of 0.7dBm, and the original negotiation rate is decreased by 5M/s according to a sixth preset step size of 0.8M/s, so as to obtain a fourth target transmission power of 4.8dBm and a fourth negotiation rate of 4.2M/s. According to the situation that the corresponding seventh packet loss rate is 33% and still greater than the poor packet loss rate threshold value under the condition that the fourth target transmission power of the wireless communication equipment is 4.8dBm and the fourth negotiation rate is 4.2M/s, in order to improve the packet loss rate as soon as possible, the fourth target transmission power of 4.8dBm can be used for replacing the original transmission power of 4.1dBm, the fourth negotiation rate of 4.2M/s can be used for replacing the original negotiation rate of 5M/s, the operation is continued according to a fifth preset step length, the original transmission power is increased, the original negotiation rate is reduced according to a sixth preset step length, the fourth target transmission power and the fourth negotiation rate are obtained, and the subsequent steps are carried out, so that the first target transmission power is determined.

In the embodiment of the present invention, for example, if the wireless communication device has a fourth target transmission power of 4.8dBm and a fourth negotiation rate of 4.2M/s, and a corresponding seventh packet loss rate of 23% is less than or equal to a poor packet loss rate threshold of 30%, the original packet loss rate of 42% may be replaced with the seventh packet loss rate of 23%, the original negotiation rate of 5M/s may be replaced with the fourth negotiation rate of 4.2M/s, and the first target transmission power may be determined according to a size relationship between the replaced original packet loss rate and 0, a size relationship between a good packet loss rate threshold of 3%, and a size relationship between the replaced original negotiation rate of 4.2M/s and a preset negotiation rate of 5M/s. That is, according to the determination condition in the embodiment of the present invention, the subsequent operation is performed to determine the first target transmission power.

For example, the first target transmission power is determined according to the size relationship between 23% and 0% of the original packet loss rate after replacement, 3% of the high-quality packet loss rate threshold and 30% of the low-quality packet loss rate threshold, and the size relationship between 4.2M/s of the original negotiation rate after replacement and 5M/s of the preset negotiation rate. If the replaced original packet loss rate is greater than the high-quality packet loss rate by 3% and less than the low-quality packet loss rate by 30%, and the replaced original negotiation rate is 4.2M/s and less than the preset negotiation rate by 5M/s, the conditions of the step 209 are met, and the steps 209 to 214 are continuously executed to determine the first target transmission power.

For another example, if the replaced original packet loss rate is 2.3%, the replaced original negotiation rate is 5.2M/s and is greater than the preset negotiation rate 5M/s, and if the high-quality packet loss rate threshold is 3% and the poor-quality packet loss rate threshold is 30%. If the replaced original packet loss rate 2.3% is greater than 0 and less than the high-quality packet loss rate 3%, and the replaced original negotiation rate 5.2M/s is greater than the preset negotiation rate 5M/s, the conditions of step 202 are met, and step 202 to step 205 are continuously executed to determine the first target transmission power.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the embodiments are not limited by the order of acts described, as some steps may occur in other orders or concurrently depending on the embodiments. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the embodiments of the application.
