[0055] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0062] Figure 6 This is a block diagram illustrating an operating state adjustment 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 in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0064] In related technologies, the APT mode corresponds to only two working states of the PA, as shown in Table 1.

[0065] Table 1

[0066] PA working status PA output power range Work mode PA state1 PA range0 APT PA state0 PA range1 APT

[0067] PA state1 can correspond to High Power Mode (HPM) to meet various RF specifications of the terminal. PA state0 can correspond to Low Power Mode (LPM) to balance terminal power consumption when outputting lower power.

[0068] If the terminal uses a PA provided by a third party on the system platform, and the channel bandwidth of the terminal is greater than or equal to a certain threshold, such as 60MHz, the PA will always work in APT mode, that is, the PA will work in the state 0-PA range 1 APT (corresponding to LPM) shown in Table 1, or in the state 1-PA range 0 APT (corresponding to HPM) shown in Table 1.

[0069] If the channel bandwidth of the terminal is less than the threshold, the PA can operate in any of the operating states shown in Table 1, or in one of the operating states corresponding to the ET mode (state2-PA range0ET).

[0070] When setting parameters, the total number of working states corresponding to the PA set for the same frequency band is fixed, usually 2 or 3. Therefore, when the channel bandwidth covered by the frequency band is wide, once the total number of working states corresponding to the PA set by the system platform is 2, the terminal can only always work in APT mode even if the channel bandwidth of the terminal is less than the above threshold.

[0071] In addition, even if the total number of PAs in the system platform meets the requirements, the PA will always work in APT mode if the channel bandwidth of the terminal is greater than or equal to the above threshold, resulting in high terminal power consumption and thus reduced terminal battery life.

[0072] To address the aforementioned technical issues, this application provides the following operational status adjustment scheme.

[0073] Figure 1 This is a flowchart illustrating a working state adjustment method according to an exemplary embodiment of this application. This embodiment is described from the terminal side, wherein the terminal includes, but is not limited to, mobile phones, laptops, desktop computers, iPads, etc., and the terminal is equipped with a PA. Figure 1 As shown, the working status adjustment method includes the following steps:

[0074] In step 101, the target channel bandwidth for the terminal to operate is determined.

[0075] In this embodiment of the disclosure, the terminal can operate in different frequency bands, each of which can cover at least one channel bandwidth. Taking the N41 frequency band as an example, it covers channel bandwidths of 20, 30, 40, 50, 60, 70, 80, 90, and 100 MHz.

[0076] In step 102, the target operating state of the PA is determined from the selectable operating states based on the target channel bandwidth, and the selectable operating states correspond to at least two operating modes.

[0077] In this embodiment of the disclosure, the PA can switch between working states corresponding to at least two working modes.

[0078] In step 103, the PA is adjusted to operate in the target operating state.

[0079] In the above embodiments, the PA can switch between working states corresponding to at least two working modes, avoiding the problem of high terminal power consumption caused by the PA always working in the same working state, thereby reducing terminal power consumption and improving terminal battery life.

[0080] In some alternative embodiments, at least two operating modes include: a first operating mode that adjusts the supply voltage based on the output power; and a second operating mode that adjusts the output power based on the supply voltage.

[0081] That is, the first operating mode can be APT mode, which adjusts the PA's supply voltage according to the PA's output power. The second operating mode can be Envelope Tracking (ET) mode, which controls the PA's output power by adjusting the PA's supply voltage. The second operating mode allows the PA to operate at near-maximum capacity.

[0082] The above is merely an illustrative example. In practical applications, at least two working modes may also include other PA working modes, which are not limited in this disclosure.

[0083] Accordingly, refer to Figure 2 As shown, Figure 2 Based on this application Figure 1 The flowchart of another working state adjustment method shown in the embodiment further includes the following steps before performing step 102 above:

[0084] In step 201, when the target channel bandwidth is greater than or equal to a preset threshold, at least three working states corresponding to the first working mode are determined as the optional working states.

[0085] In this embodiment of the disclosure, the preset threshold can be set to 60MHz. Of course, it can also be set according to the actual operating frequency band of the terminal. For example, if the operating frequency band of the terminal covers a channel bandwidth of 20, 30, ... 60MHz, the preset threshold can also be set to 40MHz. This disclosure does not limit this.

[0086] When the target channel bandwidth of the terminal is currently operating is greater than or equal to the preset threshold, the terminal can determine at least three operating states corresponding to the first operating mode as selectable operating states.

[0087] In this embodiment of the disclosure, when the total number of working states corresponding to the first working mode is greater than two, for example, when the total number is three, the working states corresponding to the first working mode may include: a first working state corresponding to the low power mode, and a second working state corresponding to the high power mode, and a third working state corresponding to the high power mode.

[0088] This application establishes a new third working state for the first working mode, denoted as PA state2', so that the first working mode can correspond to at least three working states. Accordingly, Table 1 can be updated to Table 2:

[0089] Table 2

[0090] PA working status PA output power range Work mode PA state2' PA range0 APT PA state1 PA range0 APT PA state0 PA range1 APT

[0091] In Table 2, the power range corresponding to PA state2' can be the same as the power range corresponding to PA state1, or the minimum value of the power range corresponding to PA state2' can be greater than the maximum value of the power range corresponding to PA state1. This disclosure does not limit this.

[0092] In this application, a new operating state PA state2' is set for APT mode. When the target channel bandwidth of the terminal is greater than or equal to a preset threshold, the operating state indicated in Table 2 can be determined as an optional operating state.

[0093] In step 202, when the target channel bandwidth is less than the preset threshold, at least two working states corresponding to the first working mode and one working state corresponding to the second working mode are determined as the optional working states.

[0094] In this embodiment of the disclosure, the at least two operating states corresponding to the first operating mode may include, but are not limited to, a first operating state corresponding to the low-power mode and a second operating state corresponding to the high-power mode.

[0095] If the target channel bandwidth of the terminal is less than the preset threshold, then the operating states shown in Table 3 can be determined as optional operating states:

[0096] Table 3

[0097] PA working status PA output power range Work mode PA state2 PA range0 ET PA state1 PA range0 APT PA state0 PA range1 APT

[0098] In the above embodiments, based on the target channel bandwidth of the terminal, at least three operating states corresponding to the first operating mode can be determined as selectable operating states, or at least two operating states corresponding to the first operating mode and one operating state corresponding to the second operating mode can be determined as selectable operating states. This allows the target operating state of the PA to be determined from the selectable operating states. This achieves the goal of adjusting the PA to switch between operating states corresponding to at least two operating modes, avoiding the high power consumption problem caused by the PA always operating in the same operating mode, and improving the terminal's battery life.

[0099] In some optional embodiments, as can be seen from Tables 2 and 3 above, when the terminal operates in a wide range of the same frequency band, the total number of selectable operating states corresponding to the PA is the same, which can be greater than or equal to 3. Accordingly, the total number of selectable operating states corresponding to the PA can be set to 3 by the terminal's system platform. This ensures that the PA can switch between operating states corresponding to at least two operating modes.

[0100] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 Based on this application Figure 2 The flowchart of another working state adjustment method shown in the embodiment above includes the following steps in step 102:

[0101] In step 301, the target output power corresponding to the target channel bandwidth is determined according to the first correspondence between the channel bandwidth and the output power of the PA.

[0102] In this embodiment of the disclosure, the first correspondence can be determined by calibrating the PA. For example, the first correspondence includes: when the channel bandwidth is 30MHz, the output power of the PA is 23dB.

[0103] The terminal can directly invoke the first correspondence relationship in actual operation to determine the target output power corresponding to the target channel bandwidth of the terminal's operation, based on the pre-determined first correspondence relationship.

[0104] In step 302, based on the second correspondence between the output power range and the selectable operating states, the selectable operating state corresponding to the output power range to which the target output power belongs is determined as the target operating state.

[0105] In this embodiment of the disclosure, when the target channel bandwidth is greater than or equal to a preset threshold, the target operating state corresponding to the output power range to which the target output power belongs can be determined from at least three operating states corresponding to the first operating mode according to the second correspondence indicated in Table 2.

[0106] When the target channel bandwidth is less than a preset threshold, according to the second correspondence indicated in Table 3, the target operating state corresponding to the output power range to which the target output power belongs is determined from at least two operating states corresponding to the first operating mode and the operating state corresponding to the second operating mode.

[0107] The above embodiments can quickly determine the target working status, are simple to implement, and have high availability.

[0108] In some optional embodiments, the PA may be calibrated before the terminal leaves the factory to determine the aforementioned first correspondence. Specifically, the PA may be calibrated based on the calibration parameters corresponding to each working state of each working mode, so as to determine the aforementioned first correspondence based on the calibration results.

[0109] In this embodiment of the disclosure, the calibration parameters include, but are not limited to, voltage bias value, current bias value, output power index, etc.

[0110] In one possible implementation, during PA calibration, it is necessary to calibrate the channel bandwidth corresponding to the output power indicated by different output power indices.

[0111] In this embodiment of the disclosure, the PA needs to be calibrated based on the calibration parameters corresponding to each of the three operating states corresponding to the first operating mode. Similarly, the PA also needs to be calibrated based on the corresponding calibration parameters in the operating state corresponding to the second operating mode.

[0112] The parameter values ​​of the calibration parameters corresponding to the second working state can be the same as the parameter values ​​of the calibration parameters corresponding to the third working state.

[0113] In the above embodiments, the PA can be calibrated before the terminal leaves the factory to determine the first correspondence between the channel bandwidth and the PA's output power. The parameter values ​​of the calibration parameters corresponding to the second operating state can be the same as the parameter values ​​of the calibration parameters corresponding to the third operating state. This method is simple to implement and highly usable.
