Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power, which is applied to a mobile terminal which performs data transmission with an access point through a connection channel. Referring to fig. 1, fig. 1 is a flow chart illustrating a method of dynamically adjusting transmit power according to an exemplary embodiment. As shown in fig. 1, the method includes:

and S11, detecting the communication signal intensity and the interference signal intensity in a connection channel between the mobile terminal and the access point.

And step S12, when the change degree of the communication signal intensity and/or the interference signal intensity meets the set condition, adjusting the transmitting power of the mobile terminal according to the change degree and the change direction of the communication signal intensity and/or the interference signal intensity.

The communication signal strength is a strength indicating a wireless communication signal in a connection channel between the mobile terminal and the access point, and can be calculated from an energy strength of a wireless data packet received from the access point. For example: the communication signal strength is a received signal strength indication (Received Signal Strength Indication, RSSI).

The interference signal strength is used to represent the interference strength caused by other interference signals in the connection channel between the mobile terminal and the access point to the data transmission of the mobile terminal. For example: the channel busy/idle ratio obtained by clear channel assessment (Clear Channel Assessment, CCA) may also be expressed by the calculated channel utilization.

In the embodiment of the disclosure, the transmitting power of the mobile terminal is adjusted in real time according to the communication signal intensity of the mobile terminal and the change degree of the interference signal intensity in the communication environment, so that the transmitting power is automatically adapted to the change of the communication signal intensity and the change of the interference signal intensity, the self-adaptive adjustment of the transmitting power to the channel condition and the environment interference is realized, the success rate of transmitting wireless data is improved, and the transmission distance of the wireless data is increased.

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power. Referring to fig. 2, fig. 2 is a flow chart illustrating a method of dynamically adjusting transmit power according to an exemplary embodiment. As shown in fig. 2, in this method, on the basis of the method shown in fig. 1, further includes: step S10, setting N first intervals and M second intervals; the first interval is a communication signal intensity interval, and the second interval is an interference signal intensity interval; n and M are integers greater than 1.

Step S12 shown in fig. 1 includes step S22: when the first section of the communication signal intensity changes and/or the second section of the interference signal intensity changes, the transmitting power of the mobile terminal is adjusted according to the changing degree and the changing direction of the first section and/or the second section.

N and M are the same or different. The values of N and M are set according to different application scenes. For example: setting the value of N to be 4, and setting the value of M to be 4; for another example: setting the value of N to be 2 and the value of M to be 4; for another example: setting the value of N to be 3, and setting the value of M to be 2; etc.

In the embodiment of the disclosure, different intervals are set for the communication signal intensity, different intervals are set for the interference signal intensity, and the transmitting power of the mobile terminal is correspondingly adjusted through the change of the attribution interval of the communication signal intensity and the change of the attribution interval of the interference signal intensity. In this way, the transmit power can be effectively adjusted while minimizing the throughput.

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power. This method further comprises, in step S10, on the basis of the method shown in fig. 2: setting the power variation corresponding to each pair of adjacent first intervals in the N first intervals, and setting the power variation corresponding to each pair of adjacent second intervals in the M second intervals.

In the embodiment of the disclosure, the power variation amounts of adjacent sections in different variation directions are set to be the same.

The setting mode comprises the following steps:

the length of each of the N first sections is the same or decreases in order in the direction in which the communication signal strength increases. The power variation amounts corresponding to the adjacent first sections are the same, or decrease in order in the direction in which the communication signal strength increases.

The interval length of each of the M second intervals is the same or sequentially decreases in the direction in which the interference signal intensity increases. The power variation amounts corresponding to the adjacent second sections are the same, or decrease in order along the direction in which the interference signal strength increases.

The following will exemplify the case where the communication signal strength is RSSI, where the value of RSSI is a negative value, and the larger the absolute value is, the weaker the signal strength is, and the smaller the absolute value is, the stronger the signal strength is, for example, the process of changing from-85 dBm to-55 dBm of RSSI is the process of increasing the signal strength.

Example one: as shown in table 1, when the value of N is 3, the section lengths of the 3 first sections are 10dBm. The power variation corresponding to the adjacent first interval is 0.5dBm.

TABLE 1

Example two: as shown in table 2, when the value of N is 3, the section lengths of the 3 first sections are 10dBm. The power variation corresponding to the adjacent first interval is sequentially 1dBm and 0.5dBm.

TABLE 2

Example three: when the value of N is 3, the section lengths of the 3 first sections are 15dBm, 10dBm, and 5dBm in order. The power variation corresponding to the adjacent first interval is 0.5dBm.

TABLE 3 Table 3

Example four: when the value of N is 3, the section lengths of the 3 first sections are 15dBm, 10dBm, and 5dBm in order. The power variation corresponding to the adjacent first interval is sequentially 1dBm and 0.5dBm.

TABLE 4 Table 4

In a mobile terminal, due to the limitation of the inherent setting of a chip, when the transmitting power is adjusted, only a fixed step size or an integral multiple of the fixed step size (for example, 0.5 dBm) can be adjusted, and the power variation is set to be the fixed step size or the integral multiple of the fixed step size. When the process of adjusting the transmission power is not limited thereto, the above-described power variation amount may be set according to actual needs.

When the mobile terminal has the limit of the maximum adjustment value of the transmission power, the sum of the power variation amounts corresponding to all adjacent intervals is smaller than the maximum adjustment value of the transmission power.

In step S22, adjusting the transmitting power of the mobile terminal according to the change degree and the change direction of the first belonging interval and/or the second belonging interval, including:

when the interval change direction of the attribution first interval is the direction of communication signal intensity enhancement, determining that the first transmitting power is the difference value of the current transmitting power and the first power change amount, and when the interval change direction of the attribution first interval is the direction of communication signal intensity reduction, determining that the first transmitting power is the sum value of the current transmitting power and the first power change amount; the first power change amount is a sum of power change amounts corresponding to adjacent first intervals between the attribution first interval after the change and the attribution first interval before the change.

When the interval change direction of the attribution second interval is the direction of the interference signal intensity enhancement, determining that the second transmitting power is the sum of the current transmitting power and the second power change amount, and when the interval change direction of the attribution second interval is the direction of the interference signal intensity reduction, determining that the second transmitting power is the difference value of the current transmitting power and the second power change amount; the second power variation is the sum of power variation corresponding to each adjacent second interval between the attribution second interval after the change and the attribution second interval before the change.

And determining the adjusted transmitting power according to the first transmitting power and the second transmitting power. Specifically, the maximum value of the first transmission power and the second transmission power is used as the adjusted transmission power, or the weighted sum of the first transmission power and the second transmission power is used as the adjusted transmission power.

For example, taking table 1 as an example, when the first section belonging to the RSSI changes from the 1 st first section to the 3 rd second section, the first power change amount is reduced based on the current transmission power, and the first power change amount is the sum of the power change amounts corresponding to two pairs of adjacent sections between the 3 rd first section and the 1 st first section, that is, the sum of the power change amounts corresponding to the 1 st first section and the 2 nd first section adjacent to each other and the power change amounts corresponding to the 2 nd first section and the 3 rd first section adjacent to each other (the value is 1 dBm).

For example, in table 2, when the first section belonging to the RSSI is changed from the 1 st first section to the 3 rd second section, the first power change amount is reduced based on the current transmission power, and the value of the first power change amount is 1.5 dBm.

The adjustment manner corresponding to the interference signal strength is the same as the adjustment manner of the communication signal strength, and is not exemplified here.

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power. In this method, the difference from the previous embodiment is that step S10 further includes: setting information pairs corresponding to each pair of adjacent first intervals in the N first intervals, and setting information pairs corresponding to each pair of adjacent second intervals in the M second intervals; the pair of information includes a direction of change and a corresponding amount of power change. The power variation amounts of adjacent sections in different variation directions are different.

When the communication signal strength is RSSI, as shown in table 5, the power change amounts corresponding to the adjacent first sections in different change directions are different from those shown in table 1.

TABLE 5

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power. The method is suitable for the situation that the transmitting power is allowed to be adjusted in an unfixed step or an integer multiple of the fixed step in the mobile terminal. This method further comprises, in step S10, on the basis of the method shown in fig. 2:

setting information pairs corresponding to each pair of adjacent first intervals in the N first intervals, wherein the information pairs comprise a change direction and a corresponding first proportion; when the change direction is the signal intensity increasing direction, the first proportion is smaller than 1, and when the change direction is the signal intensity decreasing direction, the first proportion is larger than 1.

Setting information pairs corresponding to each pair of adjacent second intervals in the M second intervals, wherein the information pairs comprise a change direction and corresponding second proportions; when the change direction is the signal intensity increasing direction, the second proportion is larger than 1, and when the change direction is the signal intensity decreasing direction, the second proportion is smaller than 1.

Wherein, the corresponding first proportion of each pair of adjacent first intervals in the same change direction is the same. The second proportion of each pair of adjacent second intervals corresponding to the same change direction is the same.

The following is an example when the communication signal strength is RSSI.

Example one: as shown in table 6, when the value of N is 3, the section lengths of the 3 first sections are 10dBm. The first ratio of the first adjacent pair of first sections in the signal strength increasing direction is 0.9, and the first ratio in the signal strength decreasing direction is 1.1.

TABLE 6

Wherein, the first proportion corresponding to different adjacent first intervals in the signal intensity increasing direction is sequentially reduced, and the first proportion corresponding to the signal intensity decreasing direction is sequentially increased. The second ratios of the different adjacent second sections corresponding to the signal strength increasing direction are sequentially increased, and the first ratios of the different adjacent second sections corresponding to the signal strength decreasing direction are sequentially decreased.

The following is an example when the communication signal strength is RSSI.

Example two: as shown in table 7, when the value of N is 3, the section lengths of the 3 first sections gradually decrease. . The first ratio of the first adjacent pair of first sections in the signal strength increasing direction is 0.8, and the first ratio in the signal strength decreasing direction is 1.2.

TABLE 7

For example, taking table 6 as an example, when the first section belonging to the RSSI is changed from the 1 st first section to the 3 rd second section, the current transmission power is multiplied by a first power change amount, which is a product of a first ratio between the 3 rd first section and the 1 st first section, and corresponding to two pairs of adjacent sections, that is, a product (value of 0.81) of a first ratio (0.9) corresponding to the 1 st first section and the 2 nd first section adjacent to the 2 nd first section and a first ratio (0.9) corresponding to the 3 rd first section adjacent to the 1 st first section.

For example, in table 7, when the first section belonging to RSSI is changed from the 1 st first section to the 3 rd second section, the current transmission power is multiplied by a first power change amount, and the value of the first power change amount is 0.72.

The embodiment of the disclosure provides a method for dynamically adjusting transmitting power. The method is suitable for the situation that the transmitting power is allowed to be adjusted in an unfixed step or an integer multiple of the fixed step in the mobile terminal. In the method, based on the method shown in fig. 1, when the communication signal strength and/or the variation degree of the interference signal strength meet a set condition, step S12 adjusts the transmitting power of the mobile terminal according to the communication signal strength and/or the variation degree and the variation direction of the interference signal strength, including:
