Description

Technical Field

[0001] This disclosure relates to the field of control technology, and in particular to a method and apparatus for determining transmission power, electronic equipment, and readable storage medium. Background Technology

[0002] When electronic devices such as mobile phones transmit radio waves to base stations, power exceeding a certain intensity can potentially impact human health. Therefore, the transmission function of electronic devices must comply with relevant SAR (Specific Absorption Rate) regulations.

[0003] To address this, a time-averaged SAR scheme is provided in related technologies. Electronic devices can transmit at full power (Pmax) for a period within a time window (ICNIRP and FCC have different time windows; for example, in the sub-6GHz band, ICNIRP's time window is 360s, and FCC's is 100s). During another period within the time window, they can transmit at the difference between power (Plimit) and margin (Plimit-margin), ensuring that the average power within this time window does not exceed Plimit. Here, Plimit refers to a fixed upper power limit, and margin is a downward adjustment value.

[0004] However, in related technologies, when the difference between the back-off power (Plimit) and Pmax is large in SAR scenarios, electronic devices maintain transmission at Plimit-margin power for a long time within the time window, which leads to uplink signal deterioration during that period, such as silent or dropped calls during real-time services like voice calls.

[0096] Figure 9 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation

[0097] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described below by way of example do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus consistent with some aspects of this disclosure as detailed in the appended claims. It should be noted that, without conflict, the following embodiments and features in the implementation methods can be combined with each other.

[0098] To address the aforementioned technical problems, this disclosure provides a method for determining transmission power. Figure 1 This is a flowchart illustrating a method for determining transmit power according to an exemplary embodiment. See also... Figure 1 A method for determining transmission power includes steps 11 to 13.

[0099] In step 11, the business scenario of the electronic device is obtained.

[0100] In this embodiment, the electronic device can obtain the type of the current service. When the type of the current service is non-persistent and / or non-real-time, such as web pages, microblogs, etc., the electronic device can determine that the service scenario of the electronic device is the first service scenario. When the type of the current service is persistent and real-time, such as calls, games, and data uploads, the electronic device can determine that the service scenario of the electronic device is the second service scenario.

[0101] In step 12, the upper limit and / or lower limit of the transmission power are determined according to the business scenario.

[0102] In this embodiment, the electronic device can determine the upper limit and / or lower limit of its transmission power based on the business scenario. The upper limit of transmission power refers to the maximum power (Pmax) that the electronic device is allowed to transmit within a first time period of the time window, and the lower limit of transmission power refers to the minimum power (Pmin) that the electronic device is allowed to transmit within a second time period of the time window. The first and second time periods constitute a time window, and the ratio of the first time period to the time window is the duty cycle of the upper limit of transmission power, while the ratio of the second time period to the time window is the duty cycle of the lower limit of transmission power. It is understood that the third value can be determined once two of the upper limit, lower limit, average value, and duty cycle are determined.

[0103] In one example, the electronic device can determine an upper limit for its transmit power while keeping the lower limit constant based on the business scenario. See [link to relevant documentation]. Figure 2 The process includes steps 21 and 22. In step 21, the electronic device can determine the upper limit adjustment amount of the transmit power based on the service scenario. The upper limit adjustment amount refers to the amount of power change that can be added to the transmit power based on the corresponding limit power Plimit in the SAR scenario, i.e., the power portion exceeding the aforementioned limit power. According to the definition of the upper limit adjustment amount, its value lies between 0 and the backoff power, i.e., delta is located in [0, backoff]. For example, when the service scenario is the first service scenario, the electronic device can determine the upper limit adjustment amount to be the first preset adjustment amount. As another example, when the service scenario is the second service scenario, the electronic device can determine the upper limit adjustment amount to be the second preset adjustment amount; the second preset adjustment amount is less than the first preset adjustment amount.

[0104] In this example, the first preset adjustment amount can be set to a fixed value (e.g., 5dBm) or a dynamic value. When the first preset adjustment amount is a dynamic value, see [link to relevant documentation]. Figure 3The electronic device can obtain the signal strength through steps 31 to 33. In step 31, the electronic device can obtain the current value of its transmitted and received signals. This current value can be the strength of the transmitted signal, the strength of the received signal, or the channel quality between the terminal and the base station, and can be selected according to the specific scenario; no limitation is made here. The current value is taken as the transmitted signal strength (SI). Tx ) and received signal strength (SI) Rx For example, after acquiring the transmitted signal strength and the received signal strength, the electronic device can input the transmitted signal strength and the received signal strength into a preset formula y = aSI. Tx +b SI Rx +c, and we get the current value y. Of course, technicians can adjust the calculation method according to the content of the current value, and the corresponding solution falls within the protection scope of this disclosure.

[0105] In step 32, the electronic device can determine its signal state based on the current value and a preset range. The current value is the transmitted signal strength (SI). Tx ) and received signal strength (SI) Rx For example, an electronic device can set three preset ranges: a first preset range, a second preset range, and a third preset range. The first preset range, the second preset range, and the third preset range decrease sequentially, and the three preset ranges constitute the value range of the current value. After obtaining the current value, the electronic device can compare the current value with the size of each preset range to determine which preset range the current value falls within, and determine the signal state based on the preset range it falls within.

[0106] For example, when the current value is within a first preset range, the electronic device can determine the signal state as a strong signal. Similarly, when the current value is within a second preset range, the electronic device can determine the signal state as a moderate signal. Furthermore, when the current value is within a third preset range, the electronic device can determine the signal state as a weak signal. It should be noted that the signal state can be set according to specific scenarios, such as setting it to four signal states, and the corresponding scheme falls within the protection scope of this disclosure.

[0107] Table 1. Correspondence between signal state and adjustment amount

[0108] signal status Adjustment amount Range of values Strong signal state First adjustment amount [7,9] Signal normal state Second adjustment amount [4,6] Weak signal state Third adjustment amount (0,3]

[0109] In step 33, the electronic device can determine the adjustment amount corresponding to the signal state based on a preset correspondence between signal states and adjustment amounts, and use the adjustment amount as the first preset adjustment amount. In this example, the electronic device can store a preset correspondence between signal states and adjustment amounts; Table 1 shows one such correspondence.

[0110] After acquiring the signal state, the electronic device can determine the corresponding adjustment amount based on the signal state and the aforementioned correspondence. For example, when the signal state is strong, the electronic device can determine the corresponding adjustment amount as a first adjustment amount. Similarly, when the signal state is moderate, the electronic device can determine the corresponding adjustment amount as a second adjustment amount. When the signal state is weak, the electronic device can determine the corresponding adjustment amount as a third adjustment amount.

[0111] In this way, different adjustment amounts can be set for different signal strengths in this example. That is, the adjustment amount decreases as the signal weakens, which helps to reduce the magnitude of the transmission power and avoid the transmission power duty cycle being too large during the downslope time (i.e., the second time period within the time window), thus avoiding the problem of uplink signal deterioration.

[0112] In another example, when the current scenario is a second service scenario, the electronic device can determine the upper limit as a second preset adjustment amount, and this second preset adjustment amount is less than the first preset adjustment amount. For example, when the first preset adjustment amount is 7dBm, the second preset adjustment amount can be set to 5dBm. Thus, in this example, a second preset adjustment amount, smaller than the first preset adjustment amount, can be set for the second service scenario, further reducing the transmit power to avoid an excessively high duty cycle during the downlink time. This improves the quality of the uplink signal and helps prevent problems such as dropped calls.

[0113] In step 22, the electronic device obtains the sum of the power limit under the SAR scenario and the upper limit adjustment, and determines the sum as the upper limit value of the electronic device's transmit power. The electronic device can determine its transmit power within the first time period of the time window based on the power limit under the SAR scenario and the upper limit adjustment. For example, if the power limit Plimit is 15 dBm and the upper limit adjustment is 3 dBm, then the transmit power Pmax of the electronic device is 15 + 3 = 18 dBm, as shown below. Figure 4 As shown. See also Figure 4 On the left, the backoff power in the related technology is 9dBm, so Pmax = Plimit + back off = 15 + 9 = 24dBm; on the right (i.e., the white background), the upper limit adjustment amount in this disclosure is 3dBm, so Pmax = 15 + 3 = 18dBm. Figure 4 Comparing the left and right sides, we can see that the electronic device's transmit power decreased by 24-18=6dBm during the first time interval T1 of the time window T. At this time, the transmit duration during the first time interval of the time window increased, thus making... Figure 4The transmission duration within the second time period T2 of the right-hand time window is narrower than that on the left-hand side, meaning the duty cycle of the transmission duration within the second time period is reduced. The first time period T1 and the second time period T2 constitute the time window T, i.e., T = T1 + T2.

[0114] In another example, the electronic device can determine a lower limit for its transmit power while maintaining an upper limit based on the business scenario; see [reference needed]. Figure 5 The process includes steps 51 and 52. In step 51, the electronic device determines the lower limit adjustment amount of the transmit power based on the service scenario. The lower limit adjustment amount refers to the amount of power change that can be reduced from the corresponding limit power Plimit in the SAR scenario, i.e., the power portion below the aforementioned limit power. In step 52, the electronic device obtains the difference between the limit power in the SAR scenario and the lower limit adjustment amount, and determines the difference as the lower limit value of the electronic device's transmit power.

[0115] It is understood that the aforementioned second preset adjustment amount can be set to a fixed value (such as 3dBm) or a dynamic value. When the second preset adjustment amount is a dynamic value, its setting method can refer to the setting method of the first preset adjustment amount, that is, the value of the second preset adjustment amount is determined according to the signal state of the electronic device. If the second time period can be shortened or the transmission power can be increased within the second time period, the obtained value of the second preset amount falls within the protection scope of this disclosure.

[0116] In one example, when the lower limit adjustment is a dynamic value, the electronic device can determine it based on the current business scenario. For example, when the business scenario is a first business scenario, the electronic device can determine the lower limit adjustment as a second preset adjustment (e.g., 4dBm). As another example, when the business scenario is a second business scenario, the electronic device can determine the upper limit adjustment as a third preset adjustment (e.g., 1dBm). In this example, the second preset adjustment is greater than the third preset adjustment.

[0117] It should be noted that setting the second preset adjustment amount to be greater than the third preset adjustment amount is to provide a larger downward transmission power for the second service scenario, i.e., the transmission power increases during the second time period of the time window. See [link / reference] Figure 6 The left-hand diagram corresponds to the first type of current service, with a downward adjustment of 4dBm. At this time, the transmission power of the electronic device is 15-4=11dBm. The right-hand diagram corresponds to the second type of current service, with a downward adjustment of 1dBm. At this time, the transmission power of the electronic device is 15-1=14dBm, and the transmission power is increased in the second time period.

[0118] In another example, if the electronic device continuously transmits a signal during the second time period of the time window, then the duty cycle of the transmission power during the transmission duration is 100%, with the effect as follows: Figure 7 As shown. When the duty cycle of the launch duration is less than 100% and is within the target percentage (e.g., 50%), the effect is as follows. Figure 8 As shown, the electronic device can determine the downward adjustment amount as the fourth preset adjustment amount (e.g., 5dBm). The fourth preset adjustment amount, the second preset adjustment amount, and the third preset adjustment amount decrease sequentially. In this example, the reason for setting the fourth preset adjustment amount to be greater than the second preset adjustment amount is that, with the average transmit power remaining constant, there is a situation where the transmit power is 0 during the second time period. See [link to relevant documentation]. Figure 7 During the signal transmission period, the transmission power can be increased, i.e., from... Figure 7 The P = 14 dBm shown increases to Figure 8 The P value shown is 17 dBm, thus avoiding communication quality degradation caused by continuously low transmission power.

[0119] In this way, different second preset adjustment amounts can be set for different signal strengths in this example. That is, the adjustment amount increases as the signal weakens, which is beneficial to increase the transmission power or reduce the proportion of the downshoring time, so as to avoid the transmission power duty cycle being too large during the downshoring time (i.e., the second time period within the time window) and avoid the problem of uplink signal deterioration.

[0120] In another embodiment, the electronic device can simultaneously adjust both the upper and lower limits of the transmission power; the adjustment method can be found in [reference needed]. Figures 2-7 The details of the illustrated embodiments will not be elaborated upon here.

[0121] In step 13, the electronic device is controlled to transmit and receive signals using the transmit power, and the average value of the transmit power is made to meet the SAR requirements.

[0122] Thus, the solution provided in this disclosure can obtain the service scenario of an electronic device; then, determine the upper and / or lower limit of the transmission power based on the service scenario; subsequently, control the electronic device to transmit and receive signals using the transmission power, and ensure that the average value of the transmission power meets SAR requirements. In this way, the electronic device in this embodiment does not need to transmit signals at full power. With a fixed average transmission power, the proportion of transmission power dips can be reduced, which is beneficial for improving signal quality, avoiding problems such as silent or dropped calls, and improving the user experience of the electronic device. Furthermore, the solution provided in this disclosure... Figure 1 Based on the beneficial effects of the illustrated embodiment, the downward transmission power can be increased by setting the downward adjustment amount, which is beneficial to improving signal quality and avoiding problems such as dropped calls.
