Description

Technical Field

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

[0002] During the transmission of radio waves from electronic devices to base stations, if the transmission power of the electronic device exceeds a certain level, it may have an impact on human health. Therefore, the transmission function of electronic devices needs to comply with the relevant regulations on SAR (Specific Absorption Rate).

[0003] To ensure that the transmit power meets SAR requirements, a time-averaged SAR scheme is provided in related technologies. Electronic devices can transmit at full power (Pmax) for a set time window (ICNIRP and FCC have different time windows; taking the sub-6 GHz band as an example, ICNIRP uses 360 seconds, while FCC uses 100 seconds), and then transmit at lower power for the remaining time period within the set time window, ensuring that the average power within the time window does not exceed Plimit. Here, Plimit refers to a fixed upper limit value for power.

[0004] However, the solutions provided by the relevant technologies require a long interval between high-power transmissions, which can lead to uplink signal degradation during continuous business scenarios such as gaming or voice calls, thus reducing the user experience. Summary of the Invention

[0062] Figure 9 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation

[0063] 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.

[0064] To address the aforementioned technical problems, embodiments of this disclosure provide a method for controlling transmit power. Figure 1 This is a flowchart illustrating a transmit power control method according to an exemplary embodiment. See also: Figure 1 A method for controlling transmit power, comprising steps 11 to 13.

[0065] In step 11, the target number of transmission cycles divided into a preset time window is determined according to the service scenario of the electronic device; the preset time window refers to the test cycle used when conducting SAR compliance testing on the electronic device.

[0066] 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 webpages, microblogs, or file uploads, the electronic device can determine that its service scenario is a first service scenario. When the type of the current service is persistent and real-time, such as phone calls and games, the electronic device can determine that its service scenario is a second service scenario. When the type of the current service is a mixed service type, the electronic device can determine that its service scenario is a third service scenario. A mixed service type refers to a service that includes at least one of the non-persistent and non-real-time types, as well as a persistent and real-time type; or, in other words, the current service includes both persistent and real-time types, and also non-persistent and / or non-real-time types.

[0067] In this embodiment, after determining the service scenario of the electronic device, the electronic device can determine the target number of transmission cycles to be divided into preset time windows based on the aforementioned service scenario. The preset time window refers to the test cycle used for SAR compliance testing of the electronic device. For example, ICNIRP and FCC have different time windows. Taking the sub-6GHz band as an example, the preset time window for ICNIRP is 360 seconds, while the preset time window for FCC is 100 seconds. Related technologies arrange one high-power transmission and one low-power transmission within the aforementioned preset time window. To ensure SAR requirements are met, the low-power transmission time is usually longer and is not used for continuous and real-time services.

[0068] In this embodiment, the electronic device can determine the number of targets divided into transmission cycles within a preset time window:

[0069] The more continuous and real-time types of services a business scenario includes, the larger the target number of transmission cycles that the electronic device can determine; conversely, the more non-continuous and non-real-time types of services a business scenario includes, the smaller the target number of transmission cycles that the electronic device can determine.

[0070] This is because continuous and real-time services have high real-time requirements. Taking a call as an example, in related technologies, a higher transmission power is used for transmitting and receiving signals for only one period within a preset time window (hereinafter referred to as the first time period), and the call quality is high during the first time period. However, a lower transmission power is used for transmitting and receiving signals during the remaining time periods (hereinafter referred to as the second time period), and the call quality is low during the second time period, or even the call is interrupted.

[0071] In this embodiment, a preset time window is divided into multiple transmission cycles. Each transmission cycle includes a first time period with higher transmission power and a second time period with lower transmission power. The call quality is high in the first time period and low in the second time period. Considering that the length of the second time period in each transmission cycle will be shorter than the length of the second time period in the preset time window when the number of transmission cycles increases, the second time period in each transmission cycle will enter the next transmission cycle before the call quality drops to the point of affecting the call (or the user perceives a drop in call quality). The higher transmission power will then be used to transmit and receive signals and restore the call quality to a high level, thus ensuring a high-quality call.

[0072] Taking three business scenarios as an example, electronic devices can determine the target number of launch cycles divided into preset time windows, including:

[0073] When the business scenario is a first business scenario, the electronic device can determine the target number of transmission cycles as a first number. Alternatively, when the business scenario is a second business scenario, the electronic device can determine the target number of transmission cycles as a second number. Alternatively, when the business scenario is a third business scenario, the electronic device can determine the target number of transmission cycles as a third number; the third business scenario refers to a mixed business type in the current service of the electronic device. Wherein, the first number is less than the third number, and the third number is less than the second number.

[0074] In one embodiment, considering the different proportions of continuous and real-time services in the mixed service types, the third quantity can have multiple values, all falling within the range formed when the first and second quantities are used as endpoint values. It is understood that the first, third, and second quantities can be selected with appropriate values ​​based on the specific scenario; for example, the first quantity can be 2, the second quantity 10, and the third quantity can range from 3 to 9. The corresponding solution falls within the protection scope of this disclosure.

[0075] In one embodiment, the electronic device can store a mapping relationship between business scenarios and target quantities. For example, multiple business scenarios can be constructed based on the business types supported by the electronic device, such as a first business scenario, a second business scenario, and a third business scenario. Then, the target quantity corresponding to each business scenario is determined, for example, the target quantity corresponding to the first business scenario is 2, the target quantity corresponding to the second business scenario is 10, and the target quantity corresponding to the third business scenario is 3 to 9. Afterward, the business scenarios and target quantities are mapped one-to-one to obtain a data table as a preset mapping relationship between business scenarios and target quantities, and stored in a specified location, such as a cache, local storage, or the cloud. In this way, after obtaining a business scenario, the electronic device can query the above data table according to the scenario identifier code of the business scenario to obtain the corresponding target quantity.

[0076] In step 12, the upper limit and / or lower limit of the transmission power for each transmission cycle are determined; the average value of the transmission power within the preset time window meets the SAR requirements.

[0077] In this embodiment, the electronic device can determine the upper limit and / or lower limit of its transmission power for each transmission cycle within a preset time window. The upper limit of transmission power refers to the maximum transmission power of the electronic device during the first time period of the transmission cycle, and the lower limit of transmission power refers to the minimum transmission power of the electronic device during the second time period of the time window. The first and second time periods constitute a transmission cycle, and the ratio of the first time period to the transmission cycle is the duty cycle of the upper limit of transmission power, while the ratio of the second time period to the transmission cycle is the duty cycle of the lower limit of transmission power. It is understood that the third value can be determined if two of the upper limit (or lower limit), average value, and duty cycle are known.

[0078] In one example, the electronic device can determine the upper limit of its transmit power in each transmission cycle based on the business scenario, while keeping the lower limit of the transmit power constant. See [reference needed]. Figure 2 This includes steps 21 and 22.

[0079] In step 21, the electronic device can determine the upper limit adjustment of the transmission power in each transmission cycle according to the business scenario of the electronic device. Specifically, if the upper limit value is the same for all transmission cycles within a preset time window, or if the upper limit value of at least one transmission cycle within a preset time window is different from that of other transmission cycles, the technician can select the upper limit value for each transmission cycle according to the specific business scenario.

[0080] In this step, 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 (e.g., 20dBm) for the SAR scenario; that is, the power portion exceeding the aforementioned limit power. The more continuous and real-time services included in the service scenario, the larger the upper limit adjustment amount of the transmit power can be determined by the electronic device. Alternatively, the fewer non-continuous and non-real-time services included in the service scenario, the smaller the upper limit adjustment amount of the transmit power can be determined by the electronic device. For example, when the service scenario is the first service scenario, the electronic device can determine the upper limit adjustment amount as the first adjustment amount. As another example, when the service scenario is the second service scenario, the electronic device can determine the upper limit adjustment amount as the second adjustment amount; and as yet another example, when the service scenario is the third service scenario, the electronic device can determine the upper limit adjustment amount as the third adjustment amount; the second adjustment amount is less than the third adjustment amount, and the third adjustment amount is less than the first adjustment amount.

[0081] In this example, the upper limit adjustment can be set to a fixed value (e.g., 5 dBm) or a dynamic value. When the upper limit adjustment is a dynamic value, see [link to relevant documentation]. Figure 3 The electronic device can be obtained in the following ways, including steps 31 to 33.

[0082] In step 31, the electronic device can obtain the current strength of its transmitted and received signals. This current strength 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; the choice is made according to the specific scenario and is not limited here. The current strength is defined 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 the current intensity y is obtained. Of course, technicians can adjust the calculation method according to the current intensity, and the corresponding solution falls within the protection scope of this disclosure.

[0083] In step 32, the electronic device can determine its signal state based on the current strength and a preset strength range, and determine the adjustment amount corresponding to the current strength based on a preset mapping relationship between signal states and adjustment amounts. Continuing with the assumption that the current strength is the transmitted signal strength (SI)... Tx ) and received signal strength (SI) Rx For example, an electronic device can set three preset intensity ranges: a first range, a second range, and a third range. These three ranges constitute the range of signal strength values ​​for the electronic device. Values ​​within the first range are greater than values ​​within the second range, and values ​​within the second range are greater than values ​​within the third range. After obtaining the current intensity, the electronic device can compare the current intensity with the values ​​within each preset intensity range to determine which preset intensity range the current intensity falls within, and then obtain the adjustment amount corresponding to that preset intensity range.

[0084] For example, when the current intensity is within a first range, the electronic device can determine the adjustment amount corresponding to the current intensity as a first preset adjustment amount based on a preset mapping relationship between signal states and adjustment amounts. Similarly, when the current intensity is within a second range, the electronic device can determine the adjustment amount corresponding to the current intensity as a second preset adjustment amount. Furthermore, when the current intensity is within a third range, the electronic device can determine the adjustment amount corresponding to the current intensity as a third preset adjustment amount. It should be noted that the signal states can be set according to specific scenarios, such as setting four signal states, and the corresponding scheme falls within the protection scope of this disclosure.

[0085] Table 1. Mapping relationship between preset intensity range and adjustment amount

[0086] First Scope First preset adjustment amount [7，9] Second range Second preset adjustment amount [4，6] Third Scope Third preset adjustment amount (0，3]

[0087] In this way, different upper limit adjustment amounts can be set for different signal strengths in this example. That is, the upper limit adjustment amount decreases as the signal weakens, which helps to reduce the magnitude of the transmission power and avoid the duty cycle of the transmission power being too large in the second time period of the transmission cycle, thus avoiding the problem of uplink signal deterioration.

[0088] In step 22, the electronic device obtains the sum of the power limit under the SAR scenario and the upper limit adjustment amount to obtain the upper limit value of the electronic device's transmission power in each transmission cycle.

[0089] The electronic device can determine its transmit power in the first time period of each transmission cycle based on the power limit and upper limit adjustment in the SAR scenario. That is, the upper limit value equals the sum of the power limit 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 in each transmission cycle is 15 + 3 = 18 dBm, as shown in the image. Figure 4 As shown.

[0090] See Figure 4 The left side shows the transmission power curve within a preset time window in related technologies, such as a first time period (0-20s, 24dBm) and a second time period (20-100s, 12dBm) within 0-100s; the right side shows the transmission power of each cycle in the two transmission cycles of this disclosure, such as two first time periods (300-310s, 350-360s, 24dBm) and two second time periods (310-350s, 360-400s, 12dBm) within 300-400s. Figure 4 A comparison of the left and right sides shows that within the preset time window, the number of the first time period on the right (e.g., 2) is greater than the number of the first time period on the left (e.g., 1).

[0091] See also Figure 4 When the upper limit of the transmission power on the left and right sides is the same, the duration of the first time period within the preset time window on the left side is equal to the sum of the durations of the first time period within all transmission cycles on the right side. The difference is that the increase in the number of transmission cycles on the right side increases the frequency of the first time period within the preset time window. Each first time period uses the upper limit value for transmitting and receiving signals, thereby improving the communication quality.

[0092] See Figure 5 When the upper limit of the transmission power during the right-hand transmission cycle is less than the upper limit of the transmission power during the left-hand transmission cycle, it is in contrast to... Figure 4 Compared to the upper limit values ​​shown, Figure 5The change in the upper limit value is shown by the dashed line; the sum of the durations of the first time period of all transmission cycles on the right increases, which increases the duty cycle of the larger transmission power within the preset time window, which is beneficial to improving communication quality.

[0093] In another example, the electronic device can determine a lower limit for its transmit power and keep the upper limit unchanged; see [reference needed]. Figure 6 The process includes steps 61 and 62. In step 61, 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 SAR scenario's corresponding limit power Plimit, i.e., the power portion below the aforementioned limit power. In step 62, the electronic device obtains the difference between the SAR scenario's limit power and the lower limit adjustment amount to obtain the lower limit value of the electronic device's transmit power in each transmit cycle.

[0094] It is understood that the aforementioned lower limit adjustment amount can be set to a fixed value (such as 3dBm) or a dynamic value. When the lower limit adjustment amount is a dynamic value, its setting method can refer to the setting method of the upper limit adjustment amount, that is, the value of the lower limit 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 during the second time period, the value of the obtained upper limit preset amount falls within the protection scope of this disclosure.

[0095] 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 the first business scenario, the electronic device can determine the lower limit adjustment as a fourth preset adjustment (e.g., 4dBm). As another example, when the business scenario is the second business scenario, the electronic device can determine the lower limit adjustment as a fifth preset adjustment (e.g., 1dBm). When the business scenario is the third business scenario, the electronic device can determine the lower limit adjustment as a sixth preset adjustment (e.g., 3dBm). In this example, the fourth preset adjustment is greater than the sixth preset adjustment, and the sixth preset adjustment is greater than the fifth preset adjustment. Taking the fourth preset adjustment being greater than the sixth preset adjustment as an example, this is to provide a larger lower transmission power for the third business scenario, i.e., the transmission power increases in the second time period of each transmission cycle.

[0096] The electronic device can determine its transmit power in the second time period of each transmission cycle based on the power limit and lower limit adjustment amount under the SAR scenario. For example, if the power limit Plimit is 20dBm and the lower limit adjustment amount is 6dBm, then the lower limit of the transmit power of the electronic device in each transmission cycle is 20-6=14dBm, with the effect as follows: Figure 7 As shown.

[0097] See Figure 7 The left side shows the transmission power curve within a preset time window in the related technology. For example, the preset time window of 0 to 100s includes a first time period (0 to 20s, 24dBm) and a second time period (20 to 100s, 12dBm). The right side shows the transmission power of each cycle in the two transmission cycles in this disclosure. For example, the preset time window of 300 to 400s includes two first time periods (300 to 310s, 350 to 360s, 24dBm) and two second time periods (310 to 350s, 360 to 400s, 14dBm). Figure 7 A comparison of the left and right sides reveals that within the preset time window, the number of first time segments on the right (e.g., 2) is increased compared to the number on the left (e.g., 1), resulting in a higher frequency of first time segments within the preset time window. Each first time segment uses the upper limit for signal transmission and reception, thus improving communication quality. Furthermore, the transmission power of the second time segment on the right is 2dBm higher than that on the left, which also improves the communication quality of the second communication segment.

[0098] It should be noted that the above Figure 2 The example scheme only illustrates the method of adjusting the upper limit of the transmit power in each transmit cycle. Figure 5 The illustrated scheme only demonstrates a method for adjusting the lower limit of the transmit power in each transmit cycle. In another embodiment, to better adjust the transmit power within each transmit cycle, the transmit power can be... Figure 2 and Figure 5 The proposed schemes are merged, and the upper and lower limits of the transmission power are adjusted. The merged scheme falls within the protection scope of this disclosure.

[0099] In step 13, the electronic device is controlled to transmit and receive signals using the corresponding transmit power during each transmission cycle.

[0100] Therefore, the solution provided in this embodiment can determine the target number of transmission cycles to be divided into a preset time window based on the business scenario of the electronic device; the preset time window refers to the test cycle used for SAR compliance testing of the electronic device; then, the upper limit and / or lower limit of the transmission power for each transmission cycle are determined; the average transmission power within the preset time window meets the SAR requirements; then, the electronic device is controlled to transmit and receive signals using the corresponding transmission power within each transmission cycle. In this embodiment, the preset time window is divided into a target number of transmission cycles, so that the upper limit value can be used to transmit and receive signals within each transmission cycle, or in other words, the frequency of using the upper limit value to transmit and receive signals is increased. This can improve signal quality while meeting SAR requirements, avoid problems such as silent or dropped calls, and improve the user experience of the electronic device.

[0101] Based on the transmission power control method provided in the embodiments of this disclosure, the embodiments of this disclosure also provide a transmission power control device, applied to electronic equipment, see [link to relevant documentation]. Figure 8 The device includes:
