In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides a method for adjusting transmission power. The method may be used to adjust the transmit power of a signal transceiving device. The signal transceiving equipment includes, for example, Wi-Fi equipment including an Access Point (Access Point) and a workstation (Station).
Fig. 1 is a schematic diagram of a method of adjusting transmission power according to an embodiment of the present invention. As shown in fig. 1, according to an embodiment of the present invention, the method for adjusting the transmission power at least includes an obtaining step S110, a first determining step S120, and an adjusting step S130.
An obtaining step S110, configured to obtain a retransmission rate of currently transmitted data of the signal transceiver device.
Specifically, the retransmission rate of the data currently transmitted by the signal transceiver device may be counted as a percentage of the number of frames retransmitted by the signal transceiver device when transmitting the data within a preset time to the total number of frames transmitted. The IEEE802.11 standard is equipped with a retransmission Counter (Retry Counter) for each frame to be transmitted. Each time a retransmission is made, the corresponding retransmission counter is incremented by 1. The retransmission counter may be utilized to count the number of frames retransmitted. The total number of frames to be transmitted is also provided with a counter, and the number of frames transmitted in a certain time period is counted. And comparing the value of the retransmission counter with the value of the total frame number sending counter to obtain the retransmission rate. For example, referring to fig. 2, fig. 2 is a schematic diagram of acquiring the retransmission rate of the signal transceiving equipment according to the embodiment of the present invention. As shown in fig. 2, when data is transmitted, when one frame of data is transmitted, the total transmission frame number counter is incremented by 1, if the transmission is successful, whether the data transmission is finished is judged, and if the data transmission is finished, the transmission is finished; if the data transmission is not finished, transmitting the next frame data, and adding 1 to a total frame number transmission counter; if the transmission is unsuccessful, retransmitting the frame data, and adding 1 to a retransmission counter.
A first determining step S120, configured to determine whether the retransmission rate obtained in the obtaining step S110 exceeds a set retransmission rate threshold.
The set retransmission rate threshold may specifically be a preset maximum allowable retransmission rate value, that is, an acceptable retransmission rate when the signal transceiver transmits data.
An adjusting step S130, configured to adjust the current transmission power of the signal transceiver device according to the set maximum transmission power of the signal transceiver device if it is determined in the first determining step 120 that the retransmission rate exceeds the set retransmission rate threshold.
The retransmission rate can reflect the signal-to-noise ratio of the transmitted signal, and an excessively high retransmission rate indicates an excessively low signal-to-noise ratio, and the transmission power of the device needs to be adjusted. The set maximum transmission power may specifically be the maximum transmission power that can be achieved by the signal transceiver device itself under the condition of meeting the communication standard. For example, the maximum transmit power allowed by Wi-Fi devices under the IEEE802.11 standard. After the signal transceiver establishes communication connection with other equipment, the signal transceiver transmits data by using set transmission power as default transmission power, wherein the set transmission power is less than or equal to the set maximum transmission power.
Specifically, the current transmission power is compared with the set maximum transmission power; if the current transmitting power is smaller than the set maximum transmitting power, increasing the current transmitting power according to a first power stepping value; if the current transmission power is equal to the set maximum transmission power, the current transmission power is maintained, that is, data is continuously transmitted with the current transmission power, that is, data is continuously transmitted with the set maximum transmission power, wherein after the current transmission power is increased according to a first power step value or after the duration of data transmission with the current transmission power (that is, the set maximum transmission power) by the signal transceiver device reaches a set duration transmission time, the obtaining step S110, the first determining step S120, and the adjusting step S130 are returned to be executed again, that is, the retransmission rate is returned to be obtained again, and the determination and the adjustment are performed. A sending timer may be set, and when the duration reaches the set duration time, the sending timer is cleared when the data is sent, and the process is returned to the obtaining step S110 to continue executing the process.
Fig. 3 is a schematic diagram of another embodiment of the method for adjusting transmission power provided by the present invention. As shown in fig. 3, according to the above embodiment, the method for adjusting the transmission power further includes a marking step S140.
A marking step S140, configured to set a preset power flag to 1 after the adjusting step increases the current transmission power according to the first power step value.
Specifically, if the current transmission power is smaller than the set maximum transmission power, after increasing the current transmission power according to the first power step value, setting a preset power flag bit to 1, where the power flag bit is used to mark the lowest transmission power at the allowable retransmission rate in the signal transmission process, that is, the optimal transmission power at the allowable retransmission rate, that is, after increasing the current transmission power according to the first power step value, mark the increased current transmission power as the lowest transmission power at the current retransmission rate. After the preset power flag is set to 1, the step S110, the first determining step S120 and the adjusting step S130 are executed again.
Fig. 4 is a schematic diagram of a method for adjusting transmission power according to another embodiment of the present invention. As shown in fig. 4, the method for adjusting the transmission power according to any of the above embodiments may further include a determination step S150.
A determining step S150, configured to determine whether a preset power flag is equal to 1 if the first determining step S120 determines that the retransmission rate does not exceed the set retransmission rate threshold.
The adjusting step 130 is further for: and determining whether to adjust the current transmitting power of the signal transceiving equipment or not according to whether the preset power zone bit is equal to 1 or not.
Specifically, determining whether to adjust the current transmission power of the signal transceiver device according to whether the preset power flag is equal to 1 specifically includes: if the determining step S150 determines that the preset power flag is not equal to 1, decreasing the current transmission power according to a second power step value; if the determining step S150 determines that the preset power flag is equal to 1, the current transmission power is maintained, that is, data is transmitted at the current transmission power.
Further, after the duration of transmitting data at the current transmission power reaches the set duration, the step of obtaining S110, the step of first determining S120, and the step of adjusting S130 are executed again.
Fig. 5 is a schematic diagram of a method for adjusting transmission power according to still another embodiment of the present invention. As shown in fig. 5, according to any of the above embodiments, the method for adjusting the transmission power may further include a second determination step S160.
A second determining step 160 is configured to determine whether the current transmitting power is greater than the set minimum transmitting power of the signal transceiver device after the adjusting step decreases the current transmitting power by a second power step value.
The adjusting step 130 is further for: if it is determined in the second determining step 160 that the current transmit power is less than or equal to the set minimum transmit power, the current transmit power is adjusted to the set minimum transmit power.
Specifically, the set minimum transmission power may specifically be an allowable minimum transmission power under a condition that meets a communication standard, if it is determined in the second determination step S160 that the current transmission power is less than or equal to the set minimum transmission power, the current transmission power is adjusted to the set minimum transmission power, that is, when the current transmission power is less than the set minimum transmission power, the current transmission power is adjusted to the set minimum transmission power to transmit data, and when the current transmission power is equal to the set minimum transmission power, the current transmission power is kept at the set minimum transmission power to transmit data; if it is determined in the second determining step S160 that the current transmission power is greater than the set minimum transmission power, the step S110, the first determining step S120, and the adjusting step S130 are executed again.
Further, after the current transmission power is adjusted to the set minimum transmission power, and after the duration of data transmission by the signal transceiver device reaches the set continuous transmission time, that is, the duration of data transmission with the set minimum transmission power reaches the set continuous transmission time, the method returns to perform the acquiring step S110, the first determining step S120, and the adjusting step S130 again. A sending timer may be set, and when the duration reaches the set duration time, the sending timer is cleared when the data is sent, and the process is returned to the obtaining step S110 to continue executing the process.
The following makes the necessary explanation with respect to the foregoing specific embodiments:
the signal transceiver device preferably comprises a Wi-Fi device, and may specifically include: a router, an access point (AccessPoint) and a Station (Station).
The set duration will have an impact on the power consumption and throughput performance of the signal transceiving equipment. The setting of this value depends on the operating environment of the signal transceiving equipment. If the environmental interference is less, the value can be set longer appropriately; if there is more interference in the environment, the value needs to be adjusted smaller. The larger the value is, the more the signal transceiver can adapt to a stable working environment, and the power consumption and the throughput performance of the signal transceiver can be optimized; the smaller the value, the more adaptable to changing interference environments. In practical use, the set continuous transmitting time needs to be adjusted according to specific application scenarios.
The setting of the maximum transmit power, i.e., the allowable maximum transmit power, needs to take two factors into consideration: one aspect is the setting of the transmit capabilities of the duration device itself. As the output power increases, the quality of the transmitted signal also decreases. The setting of this value needs to be performed on the premise that the transmission signal quality satisfies the IEEE802.11 standard. In IEEE802.11, Error Vector Magnitude (Error Vector Magnitude) is used to measure the quality of the transmitted signal. On the other hand, the maximum allowable transmit power needs to comply with local electromagnetic radiation emission regulations.
The preset power flag bit indicates the optimal transmitting power under the current environment. The flag is set according to the actual retransmission performance. If the retransmission rate is less than the maximum allowable value, it indicates that the current transmission power can be further reduced, and the power flag bit is kept to be 0 all the time. If the retransmission rate is larger than or equal to the maximum allowable value, the current power value is smaller, the current power value needs to be increased, the increased power value is the optimal transmitting power, and the power is marked in the position 1.
For the purpose of clearly explaining the technical solution of the present invention, the execution flow of the air supply speed determination method provided by the present invention is described below with a specific embodiment.
Fig. 6 is a schematic diagram of a method for adjusting transmission power according to an embodiment of the present invention. The embodiment shown in fig. 6 includes steps S201 to S217.
Step S201, data is transmitted with the maximum transmission power allowed by default.
Step S202, setting continuous emission time.
In step S203, the optimum power flag is cleared.
Step S204, setting a power step value, including the first power step value and the second power step value.
Step S205, a retransmission rate is counted.
Step S206, determining whether the current retransmission rate is less than or equal to the maximum allowable retransmission rate, if so, performing step S207, and if not, performing step S210.
Step S207, if the current retransmission rate is greater than the maximum allowable value of the retransmission rate, determining whether the current transmission power is less than the maximum transmission power, if so, performing step S208, otherwise, performing step S211
In step S208, if the current transmit power is smaller than the maximum transmit power, the current transmit power is increased according to the first power step value, and step S209 is executed next.
In step S209, after the current transmission power is increased by the first set power step value, the optimum power flag is set to 1, and the process returns to step S205.
In step S210, if the current retransmission rate is less than or equal to the maximum allowable retransmission rate, it is determined whether the optimal power flag is equal to 1, if so, step S211 is executed, otherwise, step S215 is executed.
Step S211, data is transmitted with the current transmission power, and step S212 is performed next.
In step S212, the transmission timer starts counting time.
Step S213, determining whether the current continuous sending time exceeds the set continuous sending time, if yes, executing step S214, otherwise, returning to step S211 to continue sending data with the current transmission power.
In step S214, if the current continuous transmission time exceeds the set continuous transmission time, the transmission timer is cleared, and the process returns to step S205.
In step S215, if the optimal power flag is not equal to 1, the current transmit power is decreased according to the second power step value, and step S216 is executed next.
Step S216 is to determine whether the current transmission power is greater than the minimum allowed transmission power, if so, the process returns to step S205, and if not, the process goes to step S217.
Step S217, the current transmission power is set to the minimum allowed transmission power, and step S211 is executed next.
The invention also provides a device for adjusting the transmitting power. The apparatus may be used to adjust the transmit power of a signal transceiving device. The signal transceiving equipment includes, for example, Wi-Fi equipment including an Access Point (Access Point) and a workstation (Station).
Fig. 7 is a schematic structural diagram of an embodiment of the apparatus for adjusting transmit power provided by the present invention. As shown in fig. 7, the apparatus 100 for adjusting transmission power includes: an acquisition unit 110, a first judgment unit 120 and an adjustment unit 130.
The obtaining unit 110 is configured to obtain a retransmission rate of data currently sent by the signal transceiver device.
Specifically, the retransmission rate of the data currently transmitted by the signal transceiver device may be counted as a percentage of the number of frames retransmitted by the signal transceiver device when transmitting the data within a preset time to the total number of frames transmitted. The IEEE802.11 standard is equipped with a retransmission Counter (Retry Counter) for each frame to be transmitted. Each time a retransmission is made, the corresponding retransmission counter is incremented by 1. The retransmission counter may be utilized to count the number of frames retransmitted. The total number of frames to be transmitted is also provided with a counter, and the number of frames transmitted in a certain time period is counted. And comparing the value of the retransmission counter with the value of the total frame number sending counter to obtain the retransmission rate. For example, referring to fig. 2, fig. 2 is a schematic diagram of acquiring the retransmission rate of the signal transceiving equipment according to the embodiment of the present invention. As shown in fig. 2, when data is transmitted, when one frame of data is transmitted, the total transmission frame number counter is incremented by 1, if the transmission is successful, whether the data transmission is finished is judged, and if the data transmission is finished, the transmission is finished; if the data transmission is not finished, transmitting the next frame data, and adding 1 to a total frame number transmission counter; if the transmission is unsuccessful, retransmitting the frame data, and adding 1 to a retransmission counter.
A first determining unit 120, configured to determine whether the retransmission rate acquired by the acquiring unit 110 exceeds a set retransmission rate threshold.
The set retransmission rate threshold may specifically be a preset maximum allowable retransmission rate value, that is, an acceptable retransmission rate when the signal transceiver transmits data.
An adjusting unit 130, configured to adjust the current transmission power of the signal transceiver device according to the set maximum transmission power of the signal transceiver device if it is determined in the first determining step 120 that the retransmission rate exceeds the set retransmission rate threshold.
The retransmission rate can reflect the signal-to-noise ratio of the transmitted signal, and an excessively high retransmission rate indicates an excessively low signal-to-noise ratio, and the transmission power of the device needs to be adjusted.
