Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a voltage control method, apparatus, electronic device, and storage medium. Background Art

[0002] Wireless communication devices such as smart phones, tablet computers, and Internet of Things devices use Wideband Code Division Multiple Access (WCDMA), 3rd generation (3G), Long-Term Evolution (LTE), LTE Advanced (4th generation (4G)), and 5th generation (5G) New Radio (NR) technologies for high-speed communication. With the development of communication technologies, the signals transmitted or received require a high peak-to-average power ratio and high bandwidth. Therefore, when the power supply of the power amplifier of the transmitter is connected to the battery, the efficiency of the power amplifier may decrease. To improve the efficiency of the power amplifier under high peak-to-average power ratio and high bandwidth, Average Power Tracking (APT) technology can be used. This technology is mainly used to optimize the efficiency and power consumption of the power amplifier during operation, improve the working efficiency of the power amplifier, and extend the working time of the battery, etc.

[0003] However, currently, the APT technology generally controls the output voltage of the power supply of the power amplifier according to the maximum power value of the input signal within a period of time. During this period, the output voltage of the power supply remains unchanged. In the next period, when the maximum power value of the input signal changes, the output voltage of the power supply of the power amplifier is adjusted down or up accordingly. The output voltage of the power supply will affect the output power and static power consumption of the power amplifier, and currently, this control method still results in a relatively large power consumption of the power amplifier. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a voltage control method, apparatus, electronic device, and storage medium to improve the problem that the existing control method results in a relatively large power consumption of the power amplifier.

[0005] In a first aspect, the embodiments of this application provide a voltage control method, and the method includes:

[0006] Obtain a voltage switching data segment in the symbol data, where the voltage switching data segment is determined based on relevant information of the receiving device, and the relevant information includes a symbol data segment that is not intercepted and used when the receiving device demodulates the received signal. The symbol data includes a cyclic prefix CP and signal data;

[0007] According to the set rules, control the output voltage of the power amplifier's power supply corresponding to the voltage switching data segment to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment.

[0008] In the above implementation process, in this solution, the symbol data segment that is not intercepted and used during signal demodulation is considered to determine the voltage switching data segment. For this voltage switching data segment, the output voltage of the power amplifier's power supply can be controlled separately to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment. Thus, on the basis of the APT control mode, within the voltage switching data segment, it is not necessary to rely on the magnitude of the input signal to control the output voltage of the power amplifier's power supply. For example, the output voltage of the power supply can be adjusted downward within the voltage switching data segment, thereby reducing the output power and static power consumption of the power amplifier, and further effectively reducing the overall power consumption of the power amplifier.

[0009] Optionally, the step of controlling the output voltage of the power amplifier's power supply corresponding to the voltage switching data segment according to the set rules includes:

[0010] Adjust the output voltage of the power amplifier's power supply corresponding to the voltage switching data segment to a set voltage value, where the set voltage value is lower than the output voltage of the power supply before the voltage switching data segment; in this way, the output voltage of the power amplifier's power supply within the voltage switching data segment can be made lower to further reduce the power consumption of the power amplifier;

[0011] And / or,

[0012] Adjust the output voltage of the power amplifier's power supply corresponding to the voltage switching data segment to a voltage with a smaller value, where the voltage with a smaller value refers to the smaller value between the output voltage of the power supply before the voltage switching data segment and the output voltage of the power supply after the voltage switching data segment; in this way, the output voltage of the power supply within the voltage switching data segment can be made lower to further reduce the power consumption of the power amplifier;

[0013] And / or,

[0014] Turn off or adjust the output voltage of the power amplifier's power supply corresponding to the voltage switching data segment to 0; in this way, more power consumption can be saved.

[0015] Optionally, the voltage switching data segment includes a CP switching data segment for the CP. The CP switching data segment is determined based on the CP segment in the symbol data that is not intercepted and used when the receiving device demodulates the received signal, or the CP switching data segment is determined based on the smallest CP segment in the symbol data that is not intercepted and used when multiple receiving devices demodulate the received signal;

[0016] Controlling the power supply of the power amplifier at the output voltage corresponding to the voltage switching data segment according to the set rules includes:

[0017] Controlling the power supply of the power amplifier at the output voltage corresponding to the CP switching data segment according to the first set rule.

[0018] In the above implementation process, voltage control can be performed within the previously intercepted CP switching data segment to save more power consumption. At the same time, the situation of multiple receiving devices is considered when determining the CP switching data segment, so it is not necessary to calculate the CP switching data segment separately for each receiving device, which can improve the calculation efficiency.

[0019] Optionally, the starting position of the CP switching data segment is the starting point of the CP in the symbol data, and the ending position of the CP switching data segment is the starting interception point where the receiving device intercepts the symbol data. In this way, flexible control can be performed on the output voltage corresponding to the CP switching data segment, and the power consumption of the power amplifier can be reduced.

[0020] Optionally, the voltage switching data segment includes a signal switching data segment for the signal data. The signal switching data segment is determined based on the signal data segment in the symbol data that is not intercepted and used when the receiving device demodulates the received signal, or the signal switching data segment is determined based on the smallest signal data segment that is not intercepted and used when multiple receiving devices demodulate the received signal;

[0021] Controlling the power supply of the power amplifier at the output voltage corresponding to the voltage switching data segment according to the set rules includes:

[0022] Controlling the power supply of the power amplifier at the output voltage corresponding to the signal switching data segment according to the second set rule.

[0023] In the above implementation process, voltage control can be performed within the signal switching data segment intercepted later to save more power consumption. At the same time, the situation of multiple receiving devices is considered when determining the signal switching data segment, so it is not necessary to calculate the signal switching data segment separately for each receiving device, which can improve the calculation efficiency.

[0024] Optionally, the starting position of the signal switching data segment is the ending interception point where the receiving device intercepts the symbol data, and the ending position of the signal switching data segment is the ending point of the signal data in the symbol data. In this way, flexible control can be performed on the output voltage of this part of the signal switching data segment, and the power consumption of the power amplifier can be reduced.

[0025] Optionally, the relevant information further includes the channel multipath delay spread between the receiving device and the transmitting device;

[0026] and / or,

[0027] The channel multipath delay spread refers to the maximum channel multipath delay spread among multiple receiving devices.

[0028] In the above implementation process, the channel multipath delay spread is also considered here, so as to reduce the impact of too long voltage switching data segments on the normal voltage output of the power amplifier.

[0029] In a second aspect, an embodiment of the present application provides a voltage control device, and the device includes:

[0030] A switching data segment acquisition module, configured to acquire a voltage switching data segment in symbol data, where the voltage switching data segment is determined based on relevant information of a receiving device, and the relevant information includes a symbol data segment that is not intercepted and used when the receiving device demodulates a received signal, and the symbol data includes a cyclic prefix CP and signal data;

[0031] A control module, configured to control the power supply of a power amplifier according to a set rule at an output voltage corresponding to the voltage switching data segment, so as to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0046] It should be noted that the terms "system" and "network" in the embodiments of the present invention can be used interchangeably. "Multiple" means two or more. In view of this, in the embodiments of the present invention, "multiple" can also be understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / ", unless otherwise specified, generally represents an "or" relationship between the associated objects before and after.

[0047] The embodiments of the present application provide a voltage control method. In this solution, the symbol data segment that is not intercepted and used during signal demodulation is considered to determine the voltage switching data segment. For this voltage switching data segment, the output voltage of the power supply for the power amplifier can be controlled separately to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment. Thus, on the basis of the APT control mode, within the voltage switching data segment, it is not necessary to rely on the magnitude of the input signal to control the output voltage of the power supply for the power amplifier. For example, the output voltage of the power supply can be adjusted downward within the voltage switching data segment, thereby reducing the output power and static power consumption of the power amplifier, and further effectively reducing the power consumption of the power amplifier as a whole.

[0048] For ease of understanding, before introducing the voltage control method provided by the present application, a brief introduction to the voltage control principle of this solution is given first.

[0049] The conventional control mode is to control the output voltage of the power supply for the power amplifier to be a fixed value, which does not change with the change of the input signal. The voltage control mode of this solution is the APT mode, which controls the magnitude of the output voltage of the power supply for the power amplifier according to the magnitude of the maximum power of the input signal within a period of time. During this period of time, the magnitude of the output voltage of the power supply for the power amplifier is as Figure 1 shown by V1, V2, and V3 in [the figure]. The output voltage of the power supply will affect the maximum output power and static power consumption of the power amplifier. Because if the output voltage of the power supply is low, the output power and static power consumption of the power amplifier will also decrease.

[0050] In some embodiments, the switching time for controlling the change of the output voltage of the power supply is generally within one symbol or one time slot, which depends on the specific control scheme of the APT mode. That is to say, within one symbol or one time slot, the output voltage of the power supply remains unchanged.

[0051] In this solution, the output voltage of the power supply is controlled in a cycle of a symbol or a time slot. On this basis, by controlling the output voltage of the power supply within the voltage switching data segment, the switching time of the output voltage of the power supply is further optimized, thereby affecting the output power and static power consumption of the power amplifier, and further reducing the power consumption of the power amplifier.

[0052] Please refer to Figure 2 , Figure 2 which is a flowchart of a voltage control method provided by an embodiment of this application. The method includes the following steps:

[0053] Step S110: Obtain the voltage switching data segment.

[0054] Taking the switching at the symbol level as an example, as Figure 3 shown, a complete symbol data consists of the signal itself S and the cyclic prefix (CP) in the time domain. The CP has no additional information content, but only copies about 7%-8% of the data at the tail of the S signal to the beginning of the data, which is to avoid inter-symbol interference caused by the channel. Figure 3 The upper horizontal line in

[0055] shows the change of the output voltage of the power supply under the conventional APT control mode. Figure 4 At the receiving side, the receiving device generally only intercepts the data of the net length of one symbol for demodulation. The signal interception is as

[0056] shown. However, the received signal is the CP + S signal. Therefore, in some channel scenarios or receiver modes, part or all of the CP, or part of the signal has no effect at the receiving side, and it is also useless transmission for the transmitting device. Therefore, in this solution, this part of the useless data can be used to perform additional voltage control separately (i.e., not relying on the conventional APT control mode) to reduce the power consumption of the transmitting device. The useless data segment in this solution is called the voltage switching data segment.

[0057] In some embodiments, the relevant information may further include the channel multipath delay spread between the receiving device and the transmitting device. That is to say, the voltage switching data segment may be determined based on the symbol data segment that is not intercepted and used when the receiving device demodulates the received signal and the channel multipath delay spread between the receiving device and the transmitting device. In this solution, the channel multipath delay spread between the transmitting device and the receiving device may also be considered. When the receiving device demodulates the signal, the length of the intercepted signal is fixed, that is, the length of signal S. However, due to the existence of the channel multipath delay spread, there is a delay in a symbol data received by the receiving device. Therefore, when the receiving device intercepts the signal, the remaining un-intercepted part should also include the part of the channel multipath delay spread. In this solution, in order to further reduce the impact of voltage switching on the transmission capacity, the part of the channel multipath delay spread may also be taken into account.

[0058] The channel multipath delay spread here may be obtained by the receiving device itself by measuring the received signal, or may be obtained by the transmitting device by measuring the signal sent by the receiving device and according to the principle of channel reciprocity.

[0059] In addition, the voltage switching data segment here may be directly read from the memory of the receiving device. The voltage switching data segment may be pre-determined and stored, or may be determined by an external device and then obtained from the external device, or may be a voltage switching data segment determined in real time by the APT control module when performing voltage control. For example, when the APT control module controls the output voltage of the power supply for the power amplifier, it obtains the relevant information of the receiving device and then determines according to the relevant information.

[0060] Step S120: Control the output voltage of the power supply for the power amplifier corresponding to the voltage switching data segment according to the set rule, so as to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment.

[0061] For the output voltage of the power supply for the power amplifier corresponding to the voltage switching data segment, it may be controlled according to the set rule. For example, the output voltage of the power supply corresponding to this voltage switching data segment may be controlled to be lower, so as to reduce the output power and static power consumption of the power amplifier, and thus the power consumption of the power amplifier can be reduced as a whole.

[0062] In the above implementation process, in this solution, the symbol data segment that is not intercepted and used during signal demodulation is considered to determine the voltage switching data segment. For this voltage switching data segment, the output voltage of the power supply for the power amplifier can be controlled separately to reduce the power consumption of the power amplifier corresponding to the voltage switching data segment. Thus, on the basis of the APT control mode, within the voltage switching data segment, it is not necessary to rely on the magnitude of the input signal to control the output voltage of the power supply for the power amplifier. For example, the output voltage of the power supply can be adjusted downward within the voltage switching data segment, thereby reducing the output power and static power consumption of the power amplifier, and further effectively reducing the power consumption of the power amplifier as a whole.

[0063] On the basis of the above embodiments, the method for obtaining the voltage switching data segment will be described below.

[0064] (1) The voltage switching data segment is determined based on the symbol data segment that is not intercepted and used when the receiving device demodulates the received signal.

[0065] As Figure 5 shown, Figure 5 shows a signal containing three symbols. Originally, in the APT control mode, voltage adjustment (i.e., voltage switching) should be performed at the initial point of CP2. However, due to the interception mode of the receiving device, if the interception starts from the middle of CP2, then the first half of the data in CP2 is of no use value, and the second half of CP of signal S2 is of no use value. Therefore, the symbol data segment that the receiving device does not intercept and use includes the length of the first half of the data in CP2 and the length of the second half of CP in S2.

[0066] Here, the length of the first half of the data in CP2 can be referred to as the CP switching data segment for CP, and the length of the second half of CP in S2 can be referred to as the signal switching data segment for the signal data. The voltage switching data segment in this solution can include the CP switching data segment and / or the signal switching data segment.

[0067] In some embodiments, the CP switching data segment is determined based on the CP segment in the symbol data that is not intercepted and used when the receiving device demodulates the received signal, or the CP switching data segment is determined based on the minimum CP segment in the symbol data that is not intercepted and used when multiple receiving devices demodulate the received signal.

[0068] It can be understood that the CP segment that the receiving device does not intercept and use is the CP switching data segment, and the minimum CP segment that multiple receiving devices do not intercept and use is the CP switching data segment. When determining the minimum CP segment, the CP segments that are not intercepted and used by each receiving device can be obtained first, and then a minimum CP segment can be selected from them as the minimum CP segment.

[0069] For example, for the CP switching data segment, it is equal to the data segment between the starting point of the CP and the starting intercept point, that is, the starting position of the CP switching data segment is the starting point of the CP in the symbol data, and its ending position is the starting intercept point where the receiving device intercepts the symbol data. In this way, the output voltage of the power supply corresponding to this part of the CP switching data segment can be flexibly controlled, without the need to control according to the conventional APT control mode, and the power consumption of the power amplifier can be reduced.

[0070] In some embodiments, the signal switching data segment can be determined based on the signal data segment in the symbol data that is not intercepted and used when the receiving device demodulates the received signal, or the signal switching data segment is determined based on the smallest signal data segment that is not intercepted and used when multiple receiving devices demodulate the received signal.

[0071] It can be understood that the signal data segment not intercepted and used by the receiving device is the signal switching data segment, and the smallest signal data segment not intercepted and used by multiple receiving devices is the signal switching data segment. When determining the smallest signal data segment, the signal data segments not intercepted and used by each receiving device can be obtained first, and then the smallest one is selected as the smallest signal data segment.

[0072] For example, for the signal switching data segment, it can be equal to the data segment between the ending intercept point and the ending point of S (signal data), that is, the starting position of the signal switching data segment is the ending intercept point where the receiving device intercepts the symbol data, and its ending position is the ending point of the signal data in the symbol data. In this way, the output voltage of the power supply corresponding to this part of the signal switching data segment can be flexibly controlled, without the need to control according to the conventional APT control mode, and the power consumption of the power amplifier can be reduced.

[0073] In some embodiments, the voltage switching data segment can also be characterized by corresponding calculation formulas. For example, if T RemoveCP represents the data segment between the intercept point and the starting point of the signal data, and if the interception starts from the starting point of the data S, then T RemoveCP is equal to 0. If the total data length of the entire CP is defined as T CP (which can be understood as the time length occupied by the data in the time domain, and the other parameters related to T can be understood in the same way), then the CP switching data segment delta1 = T CP - T RemoveCP , and for the signal switching data segment delta2 = T RemoveCP .

[0074] If T RemoveCP represents the data segment between the starting point of the CP and the starting intercept point, and the total data length of the entire CP is defined as T CP, if intercepted starting from the starting point of data S, then T RemoveCP equals T CP , then the CP switching data segment delta1 = T RemoveCP , for the signal switching data segment delta2 = T CP -T RemoveCP .

[0075] Understandably, in different definitions, the calculation formulas for its CP switching data segment and signal switching data segment may be different.

[0076] (2) The voltage switching data segment is determined based on the symbol data segment not intercepted and used when the receiving device demodulates the received signal and the channel multipath delay spread between the receiving device and the transmitting device.

[0077] In this implementation, the CP switching data segment can be determined based on the CP segment not intercepted and used by the receiving device and the channel multipath delay spread, or the CP switching data segment is determined based on the minimum CP segment not intercepted and used by multiple receiving devices and the channel multipath delay spread.

[0078] Both situations are considered in this way. Taking the above method (1) as an example, if T RemoveCP is defined to represent the data segment between the interception point and the starting point of S, and T Multipath is defined to represent the channel multipath delay spread. If intercepted starting from the starting point of data S, then T RemoveCP equals 0. Defining the data length of the entire CP as T CP , then the CP switching data segment delta1 = T CP -T RemoveCP -T Multipath , for the signal switching data segment delta2 = T RemoveCP .

[0079] If T RemoveCP is defined to represent the data segment between the starting point of the CP and the starting interception point, and the data length of the entire CP is defined as T CP . If intercepted starting from the starting point of data S, then T RemoveCP equals T CP , then the CP switching data segment deltal = T RemoveCP -T Multipath , for the signal switching data segment delta2 = T CP -T RemoveCP .

[0080] Based on the above embodiments, since there may be multiple receiving devices corresponding to the transmitting device, in order to facilitate the output voltage to adapt to these multiple receiving devices, the transmitting device can pre-obtain relevant information of the multiple receiving devices, such as pre-obtaining the symbol data segments not intercepted and used when each receiving device demodulates the signal and the channel multipath delay spread between each receiving device and the transmitting end.

[0081] In some embodiments, when the transmitting device determines the voltage switching data segment, it can be determined respectively according to the symbol data segments not intercepted and used when each receiving device demodulates the signal and / or the channel multipath delay spread between each receiving device and the transmitting device, that is, a corresponding voltage switching data segment is determined for each receiving device. If the interception methods or channel multipath delay spreads of some receiving devices are different, the lengths of the determined voltage switching data segments are also different. When the transmitting device controls the output voltage of the power supply, it can control according to the voltage switching data segments corresponding to different receiving devices.

[0082] In some other embodiments, the above-mentioned channel multipath delay spread may refer to the maximum channel multipath delay spread of multiple receiving devices. For example, first obtain the channel multipath delay spread of each receiving device, and then select the largest one from them. When the transmitting device determines the voltage switching data segment, it can be determined according to the maximum channel multipath delay spread of multiple receiving devices.

[0083] In some embodiments, the CP switching data segment in the voltage switching data segment can be determined based on the minimum CP segment among multiple receiving devices and the maximum channel multipath delay spread, and the signal switching data segment can be determined based on the minimum signal data segment among multiple receiving devices.

[0084] For example, if the voltage switching data segment is obtained in the above-mentioned manner (2), then the CP switching data segment d1 = T CP -T RemoveCP -T Multipath , and for the signal switching data segment d2 = T RemoveCP , where T CP -T RemoveCP represents the minimum CP segment not intercepted and used among multiple receiving devices, and T RemoveCP can represent the minimum signal data segment not intercepted and used among multiple receiving devices, and T Multipath represents the maximum channel multipath delay spread among multiple receiving devices.

[0085] Among them, the channel multipath delay spread in the above embodiments can be estimated by the transmitting end itself or obtained by network measurement.

[0086] In the above implementation process, this can take into account the situation of multiple receiving devices, so that it is not necessary to separately calculate the CP switching data segment or the signal switching data segment for each receiving device, which can improve the calculation efficiency.

[0087] Based on any embodiment of the present application, the voltage control mode in the present application can be the APT control mode, which adjusts the output voltage of the power supply based on the voltage adjustment period. The voltage adjustment period can be the duration of an Orthogonal Frequency Division Multiplexing (OFDM) symbol or the duration of a time slot, where a time slot includes multiple symbols.

[0088] It can be understood that the following control of the output voltage of the power supply takes one symbol as the voltage adjustment period as an example. The control when one time slot is the voltage adjustment period is the same, except that the adjustment frequency is lower when one time slot is the voltage adjustment period. For the case where one time slot is the voltage adjustment period, or more time slots and more symbols are the voltage adjustment periods, the control methods for the output voltage of the power supply are similar and will not be elaborated here one by one.

[0089] Based on the above embodiments, according to the set rules, the methods for controlling the output voltage of the power supply of the power amplifier in the voltage switching data segment include the following several types:

[0090] Method 1: Adjust the output voltage of the power supply of the power amplifier corresponding to the voltage switching data segment to a set voltage value, where the set voltage value is lower than the output voltage of the power supply before the voltage switching data segment.

[0091] As Figure 6 shown, the output voltage of the power supply is adjusted with one symbol as the voltage adjustment period. For example, the current voltage adjustment period is the data segment of CP1 + S1, and the next voltage adjustment period is the data segment of CP2 + S2. The output voltage within each voltage adjustment period is determined based on the maximum value of the input signal power.

[0092] For example, when going to the next voltage adjustment period currently, since the receiving device may only intercept a part of the data of CP2 when intercepting the signal, the un-intercepted data segment at the front part of CP2 is the voltage switching data segment delta1 (i.e., the CP switching data segment). For this part of the voltage switching data segment, the output voltage of the power supply can be controlled to a set voltage value, and the value of the set voltage value should be less than the previous output voltage.

[0093] In some embodiments, the set voltage value is less than the output voltage before the voltage switching data segment. Here, before the voltage switching data segment may refer to the non-voltage switching data segment before the voltage switching data segment. The non-voltage switching data segment refers to the non-voltage switching data segment in the previous voltage adjustment period. A voltage adjustment period may include a voltage switching data segment and a non-voltage switching data segment. The output voltage corresponding to the non-voltage switching data segment is the output voltage controlled according to the conventional APT control mode, and the output voltage corresponding to the voltage switching data segment is the output voltage controlled according to the control method of this solution.

[0094] For example, the output voltage corresponding to the voltage switching data segment is less than the output voltage determined by the signal magnitude in the CP1+S1 data segment. For example, according to the control scheme of the conventional APT, in the CP1+S1 data segment, the output voltage of its power supply needs to be controlled at 5V, and in the CP2+S2 data segment, the output voltage of its power supply needs to be controlled at 6V. At this time, before the voltage switching data segment may refer to the data segment where 5V is located, so the set voltage value can be a voltage value less than 5V.

[0095] When the receiving device intercepts the signal of CP2+S2, the length data of the second half of CP in S2 is not intercepted either. So the subsequent signal switching data segment delta2 is also a voltage switching data segment, and the output voltage of its power supply in this data segment is adjusted to the set voltage value. At this time, the set voltage value can also be lower than 5V.

[0096] In other embodiments, the set voltage values corresponding to the CP switching data segment and the signal switching data segment may be different. For example, in the CP switching data segment, the corresponding set voltage value is less than the output voltage of the non-voltage switching data segment before this CP switching data segment. At this time, the output voltage of the non-voltage switching data segment before the CP switching data segment is the output voltage of 5V corresponding to the non-voltage switching data segment in CP1+S1. So the set voltage value corresponding to the CP switching data segment can be less than 5V, and the output voltage of the non-voltage switching data segment before the signal switching data segment is the output voltage of 6V corresponding to the non-voltage switching data segment in CP2+S2. So the set voltage value corresponding to the signal switching data segment can be less than 6V.

[0097] In some other embodiments, if in the same way, the latter half of the CP in S1 should also be a voltage switching data segment. Therefore, within this data segment (delta3), according to the above control method, the output voltage of the power supply is the set voltage value, and this set voltage value should be lower than 5V. For example, if the set voltage value of the power supply corresponding to this data segment (delta3) is 4V, then before the CP switching data segment (delta1) of CP2, it can refer to the data segment where 4V is located. So, the set voltage value of the power supply corresponding to the CP switching data segment (delta1) of CP2 can be lower than 4V. That is to say, in this embodiment, if there is an adjacent voltage switching data segment before the voltage switching data segment, then the data segment before this voltage switching data segment can refer to the adjacent voltage switching data segment before it. Therefore, the set voltage value at this time can be lower than the output voltage corresponding to the adjacent voltage switching data segment before this voltage switching data segment.

[0098] In other words, if the voltage switching data segment includes a CP switching data segment and a signal switching data segment, then the set voltage value corresponding to the CP switching data segment can be lower than the output voltage corresponding to the signal switching data segment in the previous voltage adjustment period, and the set voltage value corresponding to the signal switching data segment can be lower than the output voltage corresponding to the non-voltage switching data segment in the voltage adjustment period where this signal switching data segment is located.

[0099] In the above implementation process, it can make the output voltage of the power supply lower within the voltage switching data segment, so as to further reduce the power consumption of the power amplifier.

[0100] Method 2: Adjust the output voltage of the power supply of the power amplifier corresponding to the voltage switching data segment to a smaller voltage value, and this smaller voltage value refers to the smaller value between the output voltage of the power supply before the voltage switching data segment and the output voltage of the power supply after the voltage switching data segment.

[0101] Here, the output voltage of the power supply before the voltage switching data segment can refer to the output voltage of the power supply corresponding to the non-voltage switching data segment before the voltage switching data segment. If the voltage switching data segment here refers to the CP switching data segment, then the data segment before it can refer to the non-voltage switching data segment in the previous voltage adjustment period, and the data segment after it can refer to the non-voltage switching data segment in the voltage adjustment period where this CP switching data segment is located. If it is a signal switching data segment, then the data segment before it can refer to the non-voltage switching data segment in the voltage adjustment period where this signal switching data segment is located, and the data segment after it can refer to the non-voltage switching data segment in the next voltage adjustment period.

[0102] For example, continuing with Figure 6For example, if the current voltage switching data segment is delta1, the output voltage of the non-voltage switching data segment before it is 5V, and the output voltage of the non-voltage switching data segment after it is 6V. Then, taking the smaller value, it is 5V. So, the output voltage of the power supply within the delta1 data segment can be controlled to 5V. For the voltage switching data segment delta2, the output voltage of the non-voltage switching data segment before it is 6V, and the output voltage of the non-voltage switching data segment after it is 7V. Then, taking the smaller value, it is 6V. So, the output voltage of the power supply within the delta2 data segment can be controlled to 6V.

[0103] In other embodiments, the explanation of the data segment before or after the voltage switching data segment here can also be: The data segment before or after the voltage switching data segment refers to the two adjacent data segments before and after this voltage switching data segment. For example, for the CP switching data segment, the data segment before it can refer to the signal switching data segment in the previous voltage adjustment period, and the data segment after it can refer to the non-voltage switching data segment within the voltage adjustment period where this CP switching data segment is located. If it is a signal switching data segment, the data segment before it can refer to the non-voltage switching data segment within the voltage adjustment period where this signal switching data segment is located, and the data segment after it can refer to the CP switching data segment in the next voltage adjustment period.

[0104] For example, continuing with Figure 6 For example, if the current CP switching data segment is delta1, the output voltage of the signal switching data segment before it is delta3 (suppose it is 4V), and the output voltage of the non-voltage switching data segment after it is 6V. Then, taking the smaller value, it is 4V. So, the output voltage of the power supply within the delta1 data segment can be controlled to 4V. For the signal switching data segment delta2, the output voltage of the non-voltage switching data segment before it is 6V, and the output voltage of the CP switching data segment after it is delta4 (suppose it is 5V). Then, taking the smaller value, it is 5V. So, the output voltage of the power supply within the delta2 data segment can be controlled to 5V.

[0105] In the above implementation process, it can make the output voltage of the power supply within the voltage switching data segment lower to further reduce the power consumption of the power amplifier.

[0106] Method 3: Turn off or adjust the output voltage of the power supply of the power amplifier corresponding to the voltage switching data segment to 0.

[0107] In this way, instead of referring to the output voltages corresponding to other non-voltage switching data segments, the power supply is directly turned off within the voltage switching data segment, that is, no voltage is output within this data segment. Or the output voltage of the power supply corresponding to the voltage switching data segment is directly controlled to 0, thereby greatly reducing the power consumption of the power amplifier. For example, Figure 6 for the four voltage switching data segments delta1, delta2, delta3, and delta4 in

[0108] Based on the above embodiments, when controlling the voltage of the power supply, the CP switching data segment and the signal switching data segment can be controlled separately or only one of the data segments can be controlled. For example, according to the first setting rule, the output voltage of the power supply of the power amplifier corresponding to the CP switching data segment is controlled, and / or, according to the second setting rule, the output voltage of the power supply of the power amplifier corresponding to the signal switching data segment is controlled.

[0109] It can be understood that the first setting rule and the second setting rule here can be the same or different.

[0110] For example, in the same situation, for example, the output voltages of the power supply corresponding to the CP switching data segment and the signal switching data segment can both be controlled to 0. In different situations, for example, the output voltage of the power supply corresponding to the CP switching data segment can be controlled to 0, the output voltage of the power supply corresponding to the signal switching data segment can be turned off, or the output voltage of the power supply corresponding to the CP switching data segment can be controlled to a set voltage value, and the output voltage of the power supply corresponding to the signal switching data segment can be controlled to 0. It can be understood that different control methods can be flexibly selected for the output voltages of the power supply corresponding to the two data segments specifically.

[0111] Of course, in other implementation manners, only one of the data segments can be selected for control during control. For example, if only the CP switching data segment is selected for control, the output voltage of the power supply corresponding to the CP switching data segment can be controlled to 0, while for the signal switching data segment, it can be consistent with the output voltage control within the corresponding voltage adjustment period. For example, Figure 6 in

[0112] it can be controlled that the output voltage of the power supply is 0V within the CP switching data segment delta1 in CP2, while the signal switching data segment delta2 is not controlled, that is, within the signal switching data segment, the output voltage of its power supply remains 6V.

[0113] That is to say, in the solution of the present application, a corresponding setting rule can be selected to control the output voltage of the power supply of the power amplifier in the data segment corresponding to the CP switching and / or the signal switching. The setting rules corresponding to the two data segments can be the same or different.

[0114] In the above implementation process, the output voltage of the power supply of the power amplifier can be controlled in the data segment corresponding to the CP switching and / or the signal switching, and the control rules for the two data segments can be the same or different. In this way, the control method for the power supply of the power amplifier can be flexibly selected within the two data segments.

[0132] Obtain a voltage switching data segment in the symbol data, where the voltage switching data segment is determined based on relevant information of the receiving device.

[0134] In summary, the embodiments of the present application provide a voltage control method, apparatus, electronic device, and storage medium.
