Description

Gain mode switching method and mobile terminal

Technical Field

The present invention relates to the field of communications, and in particular, to a gain mode switching method and a mobile terminal.

Background

With the rapid development of mobile communication technology and the popularization of mobile terminals, the functions of mobile terminals are becoming more and more powerful, which has been converted from a single communication tool to a small helper that people cannot keep away from daily life, such as user communication, navigation, entertainment, camera shooting, online shopping, mobile payment, etc. through mobile terminals, meanwhile, people also put forward higher requirements on the cruising ability of intelligent terminals, and how to save power becomes an important direction for improving the performance of mobile terminals.

The PA (Power Amplifier) is used in the mobile terminal to amplify the low-Power modulation signal output by the transceiver and output the amplified low-Power modulation signal to the antenna end for transmission to the outside, and therefore, the PA is a main Power consumption device of the mobile terminal on the radio frequency circuit, where the Power consumption current and the linearity parameter are main performance parameters of the PA, and the linearity parameter may be an ACLR (Adjacent Channel Leakage Ratio).

Currently, PAs are typically designed for two modes of operation: namely, a low gain mode and a high gain mode, respectively, operating in low power output and high power output states. In general, under the condition of a low gain mode, the power consumption current is small, but with the increase of control power, the problem that the linearity parameter does not meet the radio frequency development standard exists; compared with the low gain mode, in the high gain mode, under the condition of the same control power, the linearity parameter can meet the radio frequency development standard, but the problem of larger power consumption current exists, so that the power consumption is increased. In this way, in both the low gain mode and the high gain mode, the requirement of the radio frequency development standard on the linearity parameter needs to be satisfied while the power consumption current is generally required to be small, and therefore, the PA operation mode needs to be accurately switched to satisfy the requirement. This is a problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present 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.

The present invention will be described in detail with reference to specific examples.

Referring to fig. 1, a flowchart of a gain mode switching method provided in the embodiment of the present invention is shown, and is applied to a mobile terminal, where the method specifically includes the following steps:

step 101, obtaining current working environment parameters of the mobile terminal.

Generally, a processor in the mobile terminal may generate a power control command according to a position distance between the mobile terminal and the base station, where the power control command includes control power corresponding to the position distance, and if the position distance is farther, the control power is larger, and if the position distance is closer, the control power is smaller, so that the power amplifier may be controlled to operate according to the control power based on the power control command, but since the power amplifier has corresponding maximum transmit power in each gain mode, there may be a deviation between the actual transmit power and the control power, for example, the maximum transmit power of the power amplifier in the low gain mode is 5.5dBm, so that when the control power of the power amplifier in the low gain mode is greater than 5.5dBm, the transmit power of the power amplifier is still 5.5 dBm. For example, as shown in table 1, there are provided operating parameters (such as the transmission power, the consumption current, and the linearity parameter in different channels, which is described as ACLR for example) of the low gain mode of the power amplifier at normal temperature as the control power increases.

TABLE 1 operating parameters of a low gain mode of a power amplifier at ambient temperature

As can be seen from table 1, for the low gain mode, under the condition of the same control power, ACLRs corresponding to different channels at the same temperature (i.e., normal temperature) may be different, for example, under the condition that the control power is 4dBm, ACLRs corresponding to respective channels at the normal temperature (i.e., low channel, medium channel, and high channel) are respectively different, and under the condition that the control power is 5dBm, ACLRs corresponding to respective channels at the normal temperature (i.e., low channel, medium channel, and high channel) are respectively different, so that, in order to make the ACLR satisfy the radio frequency development standard (the example in the present application includes the case that the ACLR size is-37 or less), the influence of the used channel of the mobile terminal on the switching gain mode needs to be considered, that is, the corresponding transmit power threshold needs to be set under the condition that the different used channels.

For example, as shown in table 2, there are provided operation parameters (e.g., transmission power, consumption current, and linearity parameters at different temperatures, which are described as ACLR) of the low gain mode of the power amplifier in the middle channel with the increase of the control power.

TABLE 2 operating parameters of a power amplifier in the middle channel for low gain mode

As can be seen from table 2, for the low gain mode, under the condition of the same control power, ACLRs corresponding to different temperatures in the same channel (i.e., the middle channel) may be different, for example, under the condition that the control power is 4dBm, ACLRs corresponding to respective temperatures (i.e., low temperature, normal temperature, and high temperature) in the middle channel are respectively different, and under the condition that the control power is 5dBm, ACLRs corresponding to respective temperatures (i.e., low temperature, normal temperature, and high temperature) in the middle channel are respectively different, so that, in order to make the ACLRs satisfy the radio frequency development standard, the influence of the environment temperature of the mobile terminal on the switching gain mode needs to be considered, that is, corresponding transmit power thresholds need to be set under the condition of different environment temperatures.

In summary, since the ambient temperature and the used channel of the mobile terminal have an influence on the ACLR, the current operating environment parameter may include the current ambient temperature and/or the currently used channel.

And 102, determining a transmission power threshold corresponding to the current working environment parameter.

In the embodiment of the present invention, a power threshold value corresponding relationship between different gain modes and different transmission power threshold values may be obtained first, where the power threshold value corresponding relationship includes a corresponding relationship between a working environment parameter range and a transmission power threshold value; then, in this step, a transmission power threshold corresponding to a working environment parameter range in which the current working environment parameter is located may be determined based on the power threshold corresponding relationship, where a target environment temperature range corresponding to the current environment temperature and/or a target channel range corresponding to the currently used channel may be obtained based on the power threshold corresponding relationship; and determining the transmission power threshold according to the target environment temperature range and/or the target channel range.

It should be noted that, since the corresponding power threshold corresponding relationship may be preset for each gain mode, the transmit power threshold obtained in this step may be a plurality of values, that is, the transmit power threshold of each gain mode under the current operating environment parameter may be determined according to the power threshold corresponding relationship of each gain mode.

Further, when the current operating environment parameter includes the current environment temperature, the power threshold correspondence includes a correspondence between an environment temperature range and a transmission power threshold, and at this time, the step may determine, based on the power threshold correspondence, a transmission power threshold corresponding to a target environment temperature range in which the current environment temperature is located; when the current operating environment parameter includes the current used channel, the power threshold value corresponding relationship includes a corresponding relationship between a channel range and a transmission power threshold value, and at this time, the step may determine, based on the power threshold value corresponding relationship, a transmission power threshold value corresponding to a target channel range in which the current used channel is located; in the case that the current operating environment parameter includes the current environment temperature and the current used channel, the power threshold correspondence includes a correspondence between an environment temperature range, a channel range, and a transmission power threshold, and at this time, the step may determine, based on the power threshold correspondence, a target channel range in which the current used channel is located, a target environment temperature range in which the current environment temperature is located, and a corresponding transmission power threshold.

In addition, the present invention needs to establish a power threshold corresponding relationship corresponding to different gain modes in advance, specifically, in a case where the current working environment parameter includes the current environment temperature, and the power threshold corresponding relationship includes a corresponding relationship between an environment temperature range and a transmission power threshold, since a fluctuation range of the environment temperature is large, in order to reduce the dimensionality of the power threshold corresponding relationship and speed up the operation, the environment temperature may be divided into a plurality of environment temperature ranges, for example, 1 ℃ to 3 ℃ is set as a first environment temperature range, 4 ℃ to 6 ℃ is set as a second environment temperature range, 7 ℃ to 9 ℃ is set as a third environment temperature range, and so on, and if the gain mode includes a first gain mode, a second gain mode, and an nth gain mode, n is a positive integer, then, for the first environment temperature range, the method comprises the steps of collecting linearity parameters corresponding to control powers of a first gain mode of a power amplifier in a first environment temperature range, collecting linearity parameters corresponding to control powers of a second gain mode of the power amplifier in the first environment temperature range, …, and collecting linearity parameters corresponding to control powers of an nth gain mode of the power amplifier in the first environment temperature range, determining a transmission power threshold corresponding to each gain mode in the first environment temperature range according to the linearity parameters corresponding to the control powers of all the gain modes in the first environment temperature range, and similarly, obtaining the transmission power threshold of each gain mode in each environment temperature range. For example, if the gain modes of the power amplifier include a first gain mode, a second gain mode, a third gain mode, and a fourth gain mode, where the power consumption current increases as the gain mode increases, and the linearity parameter is more likely to deteriorate as the control power increases, the linearity parameter corresponding to each control power of the first gain mode in a specified environment temperature range is obtained, and the specified environment temperature range is any environment temperature range, so that the linearity parameter corresponding to each control power of the first gain mode in each environment temperature range can be obtained, and similarly, the linearity parameters corresponding to each control power of the second gain mode, the third gain mode, and the fourth gain mode in each environment temperature range can be obtained, and finally, the gain modes according to the first gain mode, the second gain mode, the third gain mode, and the fourth gain mode, And determining the transmission power threshold values of the first gain mode, the second gain mode, the third gain mode and the fourth gain mode in the specified environment temperature range according to the linearity parameters corresponding to the control powers of the third gain mode and the fourth gain mode in the specified environment temperature range.

In the case that the current operating environment parameter includes a currently used channel of the mobile terminal, and the power threshold correspondence includes a correspondence between a channel range and a transmission power threshold, since there may be many channels corresponding to the mobile terminal, the channel may be divided into a plurality of channel ranges, for example, a first channel to a fifth channel are set as a first channel range, a sixth channel to a tenth channel are set as a second channel range, an eleventh channel to a fifteenth channel are set as a third channel range, and so on, and if the gain mode includes a first gain mode, a second gain mode, and an nth gain mode, n is a positive integer, then for the first channel range, the linearity parameter corresponding to each control power is acquired when the first gain mode of the power amplifier is within the first channel range, and the second gain mode of the power amplifier is acquired within the first channel range, the linearity parameters corresponding to the control powers are … respectively, and the linearity parameters corresponding to the control powers are acquired within the first channel range of the nth gain mode of the power amplifier, and then the transmitting power threshold corresponding to each gain mode within the first channel range is determined according to the linearity parameters corresponding to the control powers within the first channel range of all the gain modes, and similarly, the transmitting power threshold of all the gain modes within each channel range can be acquired. For example, if the gain modes of the power amplifier include a first gain mode, a second gain mode, a third gain mode, and a fourth gain mode, wherein the power consumption current becomes larger as the gain mode increases, and the linearity parameter is more likely to deteriorate as the control power increases, the linearity parameter corresponding to each control power of the first gain mode in the designated channel range is obtained, and the channel range is designated as any channel range, so that the average linearity parameter corresponding to each control power of the first gain mode in each channel range can be obtained, and similarly, the linearity parameters corresponding to each control power of the second gain mode, the third gain mode, and the fourth gain mode in each channel range can be obtained, and finally, according to the linearity parameters corresponding to each control power of the first gain mode, the second gain mode, the third gain mode, and the fourth gain mode in the designated channel range, the transmission power thresholds of the first gain mode and the second gain mode, the third gain mode and the fourth gain mode within the specified channel range are determined.

Under the condition that the current working environment parameters comprise the current environment temperature and the current used channel of the mobile terminal, and the power threshold value corresponding relation comprises the corresponding relation among an environment temperature range, a channel range and a transmission power threshold value, the environment temperature can be divided into a plurality of environment temperature ranges, the channel is divided into a plurality of channel ranges, the linearity parameters corresponding to the control powers in each environment temperature range and each channel range of different gain modes of the power amplifier are collected, and then the transmission power threshold value of each gain mode in the specified environment temperature range and the specified channel range is determined according to the linearity parameters corresponding to the control powers in the specified environment temperature range and the specified channel range of all gain modes. Illustratively, if the gain modes of the power amplifier include a first gain mode, a second gain mode, a third gain mode and a fourth gain mode, wherein as the gain mode increases, the power consumption current becomes larger, and the linearity parameter is more likely to deteriorate as the control power increases, the linearity parameter corresponding to each control power of the first gain mode in a specified environment temperature range and a specified channel range is obtained, the environment temperature range is specified as any environment temperature range, and the channel range is specified as any channel range, so that the linearity parameter corresponding to each control power of the first gain mode in each environment temperature range and each channel range can be obtained, and similarly, the linearity parameter corresponding to each control power of the second gain mode, the third gain mode and the fourth gain mode in each environment temperature range and each channel range is obtained respectively, finally, the transmit power thresholds of the first gain mode, the second gain mode, the third gain mode, and the fourth gain mode in the specified ambient temperature range and the specified channel range may be determined according to the linearity parameters corresponding to the control powers of the first gain mode, the second gain mode, the third gain mode, and the fourth gain mode in the specified ambient temperature range and the specified channel range.

It should be noted that, the establishing of the power threshold corresponding relationship is to divide the environment temperature and the channel into a plurality of environment temperature ranges and a plurality of channel ranges, and of course, the invention may also set up the transmission power corresponding relationship between each working environment parameter (such as the environment temperature and/or the channel) and the transmission power threshold in advance without dividing the environment temperature and the channel, and the construction process may refer to the construction process of the power threshold corresponding relationship, which is not described again, so that the step may determine the transmission power threshold corresponding to the current working environment parameter according to the transmission power corresponding relationship.

In addition, the present invention may obtain a current working environment parameter of the mobile terminal according to a preset period, and if the current working environment parameter is the same as a historical working environment parameter of a previous period, the present invention determines that a historical transmission power threshold determined in the previous period is a transmission power threshold without obtaining a transmission power threshold again, thereby avoiding redundancy of calculation, specifically, the present invention may obtain a historical working environment parameter of the previous period, which is a previous period of a latest period corresponding to the current working environment parameter; at this time, in this step, it may be determined whether the mobile terminal meets a power threshold acquisition condition according to the historical operating environment parameter and the current operating environment parameter, and a transmit power threshold corresponding to the current operating environment parameter is acquired under the condition that it is determined that the mobile terminal meets the power threshold acquisition condition according to the historical operating environment parameter and the current operating environment parameter; and under the condition that the mobile terminal is determined not to meet the power threshold acquisition condition according to the historical working environment parameters and the current working environment parameters, determining a historical transmission power threshold determined in the previous period as a transmission power threshold. Wherein, in a case where the current operating environment parameter includes the current environment temperature and the historical operating environment parameter includes a historical environment temperature, the power threshold acquisition condition includes: the target environment temperature range is different from the historical environment temperature range corresponding to the historical environment temperature; in the case where the current operating environment parameter includes the currently used channel and the historical operating environment parameter includes a historical used channel, the power threshold acquisition condition includes: the target channel range is different from the historical channel range corresponding to the historical use channel; in the case where the current operating environment parameters include the current ambient temperature and a current channel of use, and the historical operating environment parameters include the historical ambient temperature and the historical channel of use, the power threshold acquisition condition includes: the target environment temperature range is different from the historical environment temperature range corresponding to the historical environment temperature, the target channel range is different from the historical channel range corresponding to the historical use channel, the target channel range is the channel range corresponding to the current use channel, and the target environment temperature range is the environment temperature range corresponding to the current environment temperature. In another embodiment of the present invention, since the present application may not perform range division on the ambient temperature and the channel, in this case, when the current operating environment parameter includes the current ambient temperature, and the historical operating environment parameter includes the historical ambient temperature, the power threshold obtaining condition includes: the current ambient temperature is different from the historical ambient temperature; in the case where the current operating environment parameter includes the currently used channel and the historical operating environment parameter includes a historical used channel, the power threshold acquisition condition includes: the current use channel and the historical use channel are different; in the case where the current operating environment parameters include the current ambient temperature and a current channel of use, and the historical operating environment parameters include the historical ambient temperature and the historical channel of use, the power threshold acquisition condition includes: the current ambient temperature is different from the historical ambient temperature, and the current usage channel is different from the historical usage channel, and the above examples are only illustrative, and the present invention is not limited thereto.

Step 103, when the current gain mode of the mobile terminal is different from the gain mode corresponding to the transmission power threshold and the transmission power of the mobile terminal reaches the transmission power threshold, switching the current gain mode to the gain mode corresponding to the transmission power threshold.

In the embodiment of the present invention, since the power amplifier usually employs multiple gain modes, a corresponding transmission power threshold may be set for each gain mode, and for the same gain mode, the transmission power thresholds corresponding to different operating environment parameters may also be different, so that, after the transmission power thresholds of the gain modes under the current operating environment parameters are obtained, for at least one gain mode with a mode level higher than that of the current gain mode, if the transmission power is greater than or equal to the transmission power threshold corresponding to the gain mode, the current gain mode is switched to the gain mode, and if the transmission power is greater than or equal to the transmission power thresholds corresponding to the multiple gain modes, if the at least one gain mode includes at least two gain modes, if the gain modes are gain modes included in at least two gain modes, switching the current gain mode to a gain mode corresponding to the highest mode level in the gain modes; similarly, for at least one gain mode with a mode level lower than that of the current gain mode, if the transmit power is less than or equal to the transmit power threshold corresponding to the gain mode, the current gain mode is switched to the gain mode when the at least one gain mode includes one gain mode, and if the transmit power is less than or equal to the transmit power threshold corresponding to a plurality of gain modes, which are gain modes included in the at least two gain modes, the current gain mode is switched to the gain mode corresponding to the lowest mode level among the plurality of gain modes when the at least one gain mode includes at least two gain modes. Illustratively, in the case that the gain modes include a low gain mode, a medium gain mode and a high gain mode, the ambient temperature range includes a first ambient temperature range and a second ambient temperature range, and the channel range includes a first channel range and a second channel range, if the transmission power threshold corresponding to the first ambient temperature range and the first channel range in the low gain mode is U1, the transmission power threshold corresponding to the first ambient temperature range and the first channel range in the low gain mode is U2, the transmission power threshold corresponding to the first ambient temperature range and the second channel range in the low gain mode is U3, the transmission power threshold corresponding to the second ambient temperature range and the second channel range in the low gain mode is U4, the transmission power threshold corresponding to the first ambient temperature range and the first channel range in the medium gain mode is W1, the transmission power threshold corresponding to the second ambient temperature range and the first channel range in the medium gain mode is W2, the transmission power threshold corresponding to the medium gain mode in the first environment temperature range and the second channel range is W3, the transmission power threshold corresponding to the medium gain mode in the second environment temperature range and the second channel range is W4, the transmission power threshold corresponding to the high gain mode in the first environment temperature range and the first channel range is V1, the transmission power threshold corresponding to the high gain mode in the second environment temperature range and the first channel range is V2, the transmission power threshold corresponding to the high gain mode in the first environment temperature range and the second channel range is V3, and the transmission power threshold corresponding to the high gain mode in the second environment temperature range and the second channel range is V4, then under the condition that the current working environment parameter of the mobile terminal is in the first environment temperature range and the first channel range, the transmission power threshold U1 corresponding to the low gain mode, the transmission power threshold W2 corresponding to the medium gain mode can be obtained, the transmit power threshold V1 corresponding to the high gain mode is, if the current gain mode of the mobile terminal is the medium gain mode, the medium gain mode is switched to the high gain mode when the transmit power of the mobile terminal reaches V1 (i.e., the transmit power is greater than or equal to V1), the medium gain mode is controlled to be maintained when the transmit power of the mobile terminal reaches W2 (i.e., the transmit power is greater than or equal to W2), and the medium gain mode is switched to the low gain mode when the transmit power of the mobile terminal reaches U1 (i.e., the transmit power is less than or equal to U1).

In summary, in the embodiment of the present invention, first, a current operating environment parameter of the mobile terminal may be obtained, then, a transmission power threshold corresponding to the current operating environment parameter is determined, and finally, when a current gain mode of the mobile terminal is different from a gain mode corresponding to the transmission power threshold and the transmission power of the mobile terminal reaches the transmission power threshold, the current gain mode is switched to the gain mode corresponding to the transmission power threshold. In summary, since the present application considers the external variable factors of the mobile terminal, such as the current operating environment parameters in the present application, the present application sets the corresponding transmission power threshold value for each operating environment parameter, so that the transmission power threshold value has pertinence and high accuracy.

Referring to fig. 2, a flowchart of a gain mode switching method provided in this embodiment of the present invention is shown, and is applied to a mobile terminal, where this embodiment takes as an example that a current operating environment parameter includes a current environment temperature and a current used channel, and specifically may include the following steps:

step 201, obtaining the current working environment parameters of the mobile terminal according to a preset period.

In the embodiment of the invention, the current working environment parameters comprise the current environment temperature and the current used channel.

The current environment temperature may be collected by the temperature sensor, and in addition, when the mobile terminal communicates with the base station, the base station may determine a current used channel of the mobile terminal, and send a channel identifier of the current used channel to the mobile terminal, so that the mobile terminal stores the channel identifier.

Step 202, obtaining historical working environment parameters of the previous period.

The previous cycle is the previous cycle of the latest cycle corresponding to the current working environment parameter, the historical working environment parameter may include the historical environmental temperature and the historical usage channel of the mobile terminal, and the mobile terminal may store the historical working environment parameter acquired in the previous cycle, so that the stored historical working environment parameter may be acquired in this step.

And step 203, determining whether the mobile terminal meets the power threshold acquisition condition according to the historical working environment parameters and the current working environment parameters.

Wherein the power threshold acquisition condition comprises: the target environment temperature range is different from the historical environment temperature range corresponding to the historical environment temperature, the target channel range is different from the historical channel range corresponding to the historical use channel, the target channel range is the channel range corresponding to the current use channel, and the target environment temperature range is the environment temperature range corresponding to the current environment temperature.

Executing step 204 under the condition that the mobile terminal is determined to meet the power threshold acquisition condition according to the historical working environment parameters and the current working environment parameters;

and returning to the step 201 under the condition that the mobile terminal is determined not to meet the power threshold acquisition condition according to the historical working environment parameters and the current working environment parameters.

And 204, acquiring a target environment temperature range corresponding to the current environment temperature and acquiring a target channel range corresponding to the current used channel.

The environment temperature can be divided into a plurality of environment temperature ranges in advance, the channel can be divided into a plurality of channel ranges, the environment temperature range in which the current environment temperature is located is determined as a target environment temperature range, and the channel range in which the current used channel is located is determined as a target channel range.

Step 205, determining a transmission power threshold according to the target environment temperature range and the target channel range.

In this step, power threshold value corresponding relations between different gain modes and different transmission power threshold values may be obtained, where the power threshold value corresponding relations include corresponding relations between an environment temperature range, a channel range, and a transmission power threshold value, and thus, a target environment temperature range, a target channel range, and a corresponding transmission power threshold value may be determined based on the power threshold value corresponding relations.

It should be noted that, a target environment temperature range corresponding to the current environment temperature may be obtained, and/or a target channel range corresponding to the currently used channel may be obtained, and the transmission power threshold may be determined according to the target environment temperature range and/or the target channel range.

Exemplarily, as shown in table 3, a power threshold correspondence corresponding to a target gain mode is shown, the power threshold correspondence includes a correspondence between an ambient temperature range and a channel range and a transmission power threshold sample, the target gain mode may be any gain mode, where T1, T2, T3, T4, …, Ti represent different ambient temperature ranges; CH1, CH2, CH3, CH4, …, CHj represent different channel ranges, Pij represents power threshold samples corresponding to the ith ambient temperature range and the jth channel range.

For example, when it is detected that the current environment temperature of the mobile terminal is Tx and the current used channel is CHy, if it is determined according to table 3 that the environment temperature range corresponding to Tx is Ti and the channel range corresponding to CHy is CHj, it is determined that the transmission power threshold corresponding to the target gain mode under the current operating environment parameter is Pij, and as a result, the transmission power threshold corresponding to each gain mode under the current operating environment parameter can be obtained through the power threshold corresponding relationship.

And step 206, under the condition that the current gain mode of the mobile terminal is different from the gain mode corresponding to the transmission power threshold value and the transmission power of the mobile terminal reaches the transmission power threshold value, switching the current gain mode to the gain mode corresponding to the transmission power threshold value.

Because the acquired transmission power threshold may be a plurality of values, that is, different gain modes correspond to different transmission power thresholds, for a gain mode different from the current gain mode, in this step, if the transmission power of the mobile terminal reaches the transmission power threshold, the current gain mode is switched to the gain mode corresponding to the transmission power threshold; and if the transmitting power of the mobile terminal does not reach any transmitting power threshold value, controlling the mobile terminal to keep the current gain mode. For details, reference may be made to step 103, which is not described again.

And step 207, controlling the mobile terminal to maintain the current gain mode under the condition that the current gain mode of the mobile terminal is the same as the gain mode corresponding to the transmission power threshold and the transmission power of the mobile terminal reaches the transmission power threshold.
