[0058] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0059] like Figure 1 As shown, an embodiment of the present invention provides a method for obtaining a control voltage of a power amplifier, which is applied to a network device. The method includes:

[0060] Step 11: receiving first information transmitted by a baseband unit of a network device, where the first information includes statistical information related to a carrier;

[0061] Step 12: output peak power according to the first information and the second information;

[0062] Step 13: According to the peak power, a target lookup table is searched to obtain a control voltage signal of the power amplifier, wherein the target lookup table is related to the peak power of the network device and the operating temperature of the network device.

[0063] Here, the baseband unit in step 11 has a statistical function of carrier-related information, such as statistics on the number of PRBs (physical resource blocks). In an embodiment of the present invention, the baseband unit needs to upgrade the statistical function to perform statistics in units of the minimum scheduling unit, and the statistical results include the PRB usage of all physical channels and physical signals.

[0064] In this embodiment, the first information includes: carrier bandwidth configuration information, rated power configuration information of each carrier, number of physical resource blocks of each carrier, and temperature; the second information may include: peak-to-average ratio, where one peak-to-average ratio corresponds to one power range.

[0065] The implementation process of the above embodiment is described below with reference to the specific drawings:

[0066] like Figure 2 FIG. 1 shows a specific implementation process of a method for obtaining a control voltage of a power amplifier according to the present invention. The network device may be a base station, which includes a baseband unit, a DUC (digital up converter); a CFR (peak-to-average ratio clipping); a DPD (digital predistortion), a transceiver, a time adjustment module, and a power amplifier. The process includes:

[0067] Step 1: Controlling the voltage signal generating unit to receive first information transmitted by the baseband unit;

[0068] Step 2: The control voltage signal generating unit obtains a control voltage signal according to the first information and the second information pre-stored locally;

[0069] Step 3: The control voltage signal generating unit outputs the control voltage signal to the DPD module.

[0070] In the above-mentioned embodiment of the present invention, the carrier bandwidth configuration information and the rated power configuration information of each carrier included in the first information do not need to be updated in real time, and only need to be updated when the configuration is changed; the number of physical resource blocks and temperature information of each carrier need to be updated in real time with the minimum resource scheduling unit.

[0071] In an optional embodiment of the present invention, the above step 12 may include:

[0072] 121. Determine a mean power according to the carrier bandwidth configuration information, the rated power configuration information of each carrier, and the number of physical resource blocks of each carrier;

[0073] 122. Determine peak power according to the mean power and the peak-to-average power ratio.

[0074] The above step 121 can be specifically implemented by the following formula:

[0075] Pave=M1 / L1*P1+M2 / L2*P2+…Mn / Ln*Pn;

[0076] Where Pave is the output mean power; M1, M2, ..., Mn is the number of resource blocks used for each carrier; P1, P2, ..., Pn is the rated configured power for each carrier; L1, L2, ..., Ln is the total number of resource blocks for each carrier;

[0077] Ppeak=Pave+PAR;

[0078] Where Ppeak is the output peak power; Pave is the output average power; and PAR is the corresponding peak-to-average ratio.

[0079] In the above embodiment of the present invention, the above step 13 may include:

[0080] The time adjustment module adjusts the time between the baseband unit to DUC and the baseband unit to CFR, and the difference between the time used in the calculation process of the control signal search unit above, and adjusts them to be the same so that the time of subsequent signals arriving at the DPD is the same.

[0081] In an optional embodiment of the present invention, the target lookup table is obtained by the following process:

[0082] like Figure 3 As shown, the process of determining the target lookup table includes:

[0083] Step 131, determining a segmented lookup table for peak power, temperature, and voltage signal configurations;

[0084] Step 132: Determine the target lookup table according to the peak power threshold, the temperature threshold, and the segmented lookup table.

[0085] The process of determining the segmented lookup table includes:

[0086] Step 1311, determining the number N of segments configured for the voltage signal;

[0087] Step 1312: Determine the number of peak power range segments M and the number of temperature range segments P based on the number of segments N, the peak power threshold, and the temperature threshold; M is less than or equal to N, and P is less than or equal to N.

[0088] Step 1313: According to the segment number N, determine the range segment number M of the peak power and the range segment number P of the temperature to form a segment lookup table.

[0089] In specific implementation, first determine the number N of voltage configurations based on the capacity of the voltage regulating power supply; then determine the segments of power P, the number of which is less than or equal to N. Preferably, the segments of P do not exceed N and are as close to N as possible; finally, set the temperature based on the temperature fluctuation range, with the number not exceeding N. Based on the sensitivity of the power amplifier to temperature, the fewer the number, the better.

[0090] This can be shown in Table 1 below:

[0091]

[0092]

[0093] Table 1

[0094] As shown in Table 1, voltage regulation configuration sets the control voltage signal value; power setting P sets the output peak power threshold; and temperature setting T sets the temperature range. Note that in the information lookup table, temperature T does not correspond to output peak power Ppeak; voltage configuration values ​​are related to power P and T.

[0095] In an optional embodiment of the present invention, the peak power threshold in the segmented lookup table is divided and determined in at least one of the following ways: dividing the threshold of the power sensitive area according to a first interval value; dividing the threshold of the power non-sensitive area according to a second interval value; dividing the threshold of the entire working power area at equal intervals according to a third interval value.

[0096] Specific as Figure 4As shown, the threshold of power P is: in sensitive areas, a small interval is used, and in non-sensitive areas, a large interval is used.

[0097] In an optional embodiment of the present invention, the temperature thresholds in the segmented lookup table are divided and determined in at least one of the following ways: dividing the temperature thresholds into linear equal parts; dividing the temperature thresholds into probability intervals according to a temperature probability curve.

[0098] Specific as Figure 5 and Figure 6 As shown, the threshold value of temperature T: The influence of temperature on the power amplifier is generally linear, and the threshold value can be linearly divided into equal parts, that is, Figure 5 The division method shown in the figure can also be divided into fine divisions in the temperature probability curve and the high probability interval, that is, Figure 6 The division shown.

[0099] In an optional implementation example, assume the voltage adjustment range is 20-36V, and there are five output gears: 20V, 24V, 28V, 32V, and 36V. Assume the maximum peak output power of the device is 60dBM, and the operating temperature range is -20 degrees to 65 degrees. As long as the operating temperature range is 20-50 degrees, the preset values ​​are as follows:

[0100] Voltage regulation configuration Power P Temperature T Voltage Configuration 1: 36V Ppeak≥57 T≥50 Voltage Configuration 2: 32V 57≥Ppeak≥55 50≥T≥35 Voltage Configuration 3: 28V 55≥Ppeak≥53 35≥T≥20 Voltage Configuration 4: 24V 53≥Ppeak≥50 20≥T≥0 Voltage Configuration 5: 20V 50≥Ppeak 0≥T

[0101] Table 2

[0102] As shown in Table 2, the control voltage signal configuration is set to five gears of 20V, 24V, 28V, 32V and 36V in the range of 20V to 36V; since the operating temperature range is 20-50 degrees and the maximum peak output power of the device is 60DBM, Table 2 is obtained.

[0103] According to this embodiment, when the temperature T ≥ 50, the power Ppeak ≥ 57, the control voltage signal is 36V; when the temperature 50 ≥ T ≥ 35, the power 57 ≥ Ppeak ≥ 55, the control voltage signal is 32V; when the temperature 35 ≥ T ≥ 20, the power 55 ≥ Ppeak ≥ 53, the control voltage signal is 28V; when the temperature 20 ≥ T ≥ 0, the power 53 ≥ Ppeak ≥ 50, the control voltage signal is 24V; and when the temperature 0 ≥ T, the power 50 ≥ Ppeak, the control voltage signal is 20V. It should be noted in the information lookup table that there is no corresponding relationship between the temperature T and the output power peak value Ppeak.

[0104] In an optional embodiment of the present invention, step 132 may include:

[0105] Step 1321 , testing each peak power threshold value with the voltage value within each temperature threshold range to obtain multiple control voltage signal values;

[0106] Step 1322 : De-duplicate or merge identical control voltage signal values ​​from the multiple control voltage signal values ​​to obtain a target lookup table consisting of peak power threshold ranges, temperature threshold ranges, and corresponding control voltage signal values.

[0107] When forming a threshold and supply voltage lookup table, each power threshold range can be used to traverse all temperatures and obtain a voltage configuration value respectively. In this way, the same voltage configuration value may be obtained, and the same voltage configuration value can be merged.

[0108] Based on actual training and testing, a lookup table is formed. The specific lookup table format is as follows. The same voltage configuration can be merged. The information lookup table obtained by training is shown in Table 3 below:

[0109] Power P Temperature T Voltage regulation configuration Ppeak≥Pth1 T≥Tth1 Voltage Configuration 1 Ppeak≥Pth1 Tth1≥T≥Tth2 Voltage Configuration 2 …… …… …… Ppeak≥Pth1 Tthp≥T Voltage Configuration x Pth1≥Ppeak≥Pth2 T≥Tth1 Voltage Configuration 2 Pth1≥Ppeak≥Pth2 Tth1≥T≥Tth2 Voltage Configuration 3 Pth1≥Ppeak≥Pth2 …… …… Pth1≥Ppeak≥Pth2 Tthn≥T Voltage Configuration x …… …… Ppeak≥Pthl T≥Tth1 Voltage Configuration x Ppeak≥Pthl Tth1≥T≥Tth2 Voltage Configuration x Ppeak≥Pthl …… Voltage Configuration x Ppeak≥Pthl Tthn≥T Voltage Configuration x

[0110] Table 3

[0111] As shown in Table 3, voltage regulation configuration is to configure the value of the control voltage signal; setting power P is to set the threshold of output peak power; setting temperature T is to set the temperature range. In the information lookup table, it should be noted that there is no corresponding relationship between temperature T and output power peak value Ppeak.

[0112] As can be seen from the above table, the table finally formed after actual training may have different output peak power thresholds and temperature thresholds, but the control voltage signals are the same. In this case, the same voltage configurations can be merged. Specific embodiment:

[0114]

[0115]

[0116] Table 4

[0117] Table 4 is an information lookup table obtained through actual training. When the control voltage signal is 36V, only Ppeak≥57 and T≥50 are 36V, so no merging is required. When the control voltage signal is 32V, when 50≥T≥35 and 35≥T≥20, the control voltage signals are the same, so merging is required.

[0118] In the information lookup table, it should be noted that there is no corresponding relationship between the temperature T and the output power peak value Ppeak.

[0119] In a specific embodiment: the base station opens one 100M NR carrier (the corresponding total number of RBs is 273) and one 20M LTE carrier (the corresponding total number of RBs is 100), the configured power of the NR carrier is 200W, the configured power of the LTE carrier is 40W, the number of NR carrier RB applications of the resource scheduling unit T1 is 150, the number of LTE carrier RB applications is 70, and the peak-to-average ratio is 7.5Db.

[0120] Calculate the output mean power:

[0121] Pave = 200*(150 / 273)+40*(70 / 100) = 138W, equal to 51.4dBm;

[0122] Peak power: 51.4+7.5=58.9dBm;

[0123] Assuming the board temperature is 34 degrees, the corresponding voltage configuration is 2, that is, 32V.

[0124] In an optional embodiment of the present invention, the method for obtaining the control voltage of the power amplifier may further include, after step 13, the following steps:

[0125] Step 14: Determine the current pre-distortion coefficient of the DPD module according to the control voltage signal, the operating temperature of the network device, and the pre-distortion coefficient pre-stored in the DPD module.

[0126] In specific implementation, because this function has relatively high requirements for the DPD cycle, in the initial state of the power amplifier working point state switching, since the power amplifier still uses the pre-distortion coefficient of the previous state, it will instantly cause poor DPD effect. Therefore, a pre-stored training coefficient function is added to the DPD module. The pre-stored coefficient is related to the power supply voltage and temperature of the power amplifier. Each combination of voltage and each temperature corresponds to a set of coefficients. At the beginning of the power amplifier working state switching, this set of coefficients is used, and new coefficients are applied after the real-time training results are generated. This can avoid the problem of linear deterioration caused by the initial switching of the power amplifier working state.

[0127] The above-mentioned embodiment of the present invention provides a solution for adjusting the power supply of the power amplifier in real time according to the amplitude, mean and peak value of the signal power within the minimum scheduling time unit. There is no similar application in the existing technology. This solution can eliminate the use of a cache module in application and also reduce power consumption.
