In the embodiment of the application, the power control tolerance information sent by the terminal is received, and the TPC command is determined according to the power control tolerance information to instruct the uplink transmission power of the terminal. The TPC command can be determined by considering the tolerance of the terminal, i.e. the power control radio frequency error, so that the TPC command will not fail due to the power control radio frequency error of the terminal, thereby solving the problem that the existing TPC command fails due to the power control radio frequency error of the terminal.

Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a power control method, apparatus and related equipment. Background Technology

[0002] The terminal adjusts its transmit power according to the Transmit Power Control (TPC) command sent by the network-side device. In practical applications, the applicant of this application has found that TPC commands often instruct the terminal to increase its power, but in reality, the terminal reduces its power. For example, if the terminal's current actual output power is 15dBm and the terminal's target transmit power is 20dBm, and the network-side device instructs the terminal to increase its power by 5dB using a TPC command, the terminal's actual output power will decrease by 3dB after adjusting according to the TPC command. This means that although the TPC command instructs the terminal to increase its power by 5dB, the terminal actually reduces its power by 3dB, and the TPC command fails.

[0003] The applicant investigated this phenomenon and ultimately found that the existing TPC command generation method is relatively simple and does not take into account the radio frequency error of the actual power control of the terminal. This will cause over-adjustment or improper adjustment of the terminal power according to the TPC command, resulting in the above-mentioned TPC command failure. That is, there is a problem in the existing technology where the existing TPC command fails due to the power control radio frequency error of the terminal. Summary of the Invention

[0004] This application provides a power control method, apparatus, and related equipment, which solves the problem of existing TPC commands failing due to power control radio frequency errors in the terminal.

[0005] To solve the above problems, this application is implemented as follows:

[0025] In this embodiment, power control tolerance information sent by the receiving terminal is used to determine the TPC command to indicate the uplink transmit power of the terminal. This allows the TPC command to be determined while taking into account the terminal's tolerance, i.e., power control RF error, ensuring that the TPC command will not fail due to power control RF error in the terminal. This solves the problem of existing TPC commands failing due to power control RF error in the terminal. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1 , Figure 1 This is a structural diagram of a network system to which the embodiments of this application can be applied, such as... Figure 1 As shown, it includes a network-side device 11 and a terminal 12. The network-side device 11 and the terminal 12 can communicate with each other.

[0038] Network-side equipment 11 can be a base station, access point, or other network element. Terminal 12 can also be called user equipment (UE). In practical applications, the terminal can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted equipment, etc.

[0039] The power control method provided in the embodiments of this application will be described below.

[0040] See Figure 2 , Figure 2 This is one of the flowcharts of the power control method provided in the embodiments of this application. Figure 2 The method shown can be executed by network-side device 11.

[0041] like Figure 2 As shown, the power control method may include the following steps.

[0042] Step 201: Receive power control tolerance information sent by the terminal;

[0043] The power control tolerance information includes a tolerance value, which is the radio frequency error of the terminal's actual power control. In the embodiments of this application, the tolerance value is the maximum difference between the terminal's indicated transmit power and the actual transmit power. The actual transmit power is the power actually emitted by the terminal based on the indicated transmit power. The terminal's tolerance value is related to at least one of the following factors: operating frequency range, operating frequency band, transmit power, relative transmit power, and the method of TPC command.

[0044] There are two types of TPC commands: the first is in transmit power form, which instructs the receiving terminal to transmit signals at the informed transmit power; the second is in relative transmit power form, which instructs the receiving terminal to transmit signals at a power obtained by increasing or decreasing the absolute value of the relative transmit power on top of the current transmit power. When the terminal's operating frequency range and operating frequency band do not affect the terminal's tolerance value, only the TPC command method differs. Therefore, the first correspondence described below is different from the sixth correspondence, and the second correspondence is also different from the seventh correspondence. Specifically, if a terminal's tolerance is only affected by its operating frequency range and TPC command method, then even with the same operating frequency range but different TPC command methods, the tolerance values ​​in the first correspondence and the sixth correspondence can be different, but the possibility of them being the same cannot be ruled out. Similarly, the tolerance values ​​in the second and seventh correspondences can be the same or different. Furthermore, it should be noted that, assuming the tolerance value influence factors mentioned above are all the same, the tolerance values ​​in the third to fifth correspondences and the eighth to tenth correspondences mentioned below may be different or the same.

[0045] When the TPC command is in the first mode, the power control tolerance information includes at least one of the following:

[0046] The target tolerance value is a tolerance value corresponding to the first information; the first information includes at least one of the terminal's current operating frequency, target transmit power, and target relative transmit power; the target relative transmit power is the difference between the target transmit power and the terminal's current transmit power.

[0047] First tolerance information, the first tolerance information includes a first correspondence between the operating frequency range and the tolerance value;

[0048] The second tolerance information includes a second correspondence between the operating frequency band and the tolerance value;

[0049] The third tolerance information includes a third correspondence between the transmission power and the tolerance value, wherein the transmission power includes the target transmission power;

[0050] The fourth tolerance information includes a fourth correspondence between the transmit power, the operating frequency range, and the tolerance value.

[0051] The fifth tolerance information includes the fifth correspondence between the transmit power, the operating frequency band, and the tolerance value.

[0052] The aforementioned target relative transmit power can be predetermined by the base station based on the target transmit power and the terminal's current transmit power. The difference between the target transmit power and the terminal's current transmit power is the target relative transmit power. For example, if the terminal's current transmit power is 15dBm and the target transmit power is 20dBm, then the base station initially determines the target relative transmit power to be +5dB, meaning the terminal's transmit power is increased by 5dB.

[0053] The aforementioned target relative transmit power can also be predetermined by the base station based on the target received power and the terminal's current transmit power. The target transmit power can be determined by first subtracting path loss from the target received power, and then the target relative transmit power can be preliminarily determined based on the target transmit power and the terminal's current transmit power.

[0054] When the TPC command is in the second mode, the power control tolerance information includes at least one of the following:

[0055] The target tolerance value is a tolerance value corresponding to the first information; the first information includes at least one of the terminal's current operating frequency, target transmit power, and target relative transmit power; the target relative transmit power is the difference between the target transmit power and the terminal's current transmit power.

[0056] The sixth tolerance information includes a sixth correspondence between the operating frequency range and the tolerance value;

[0057] The seventh tolerance information includes a seventh correspondence between the operating frequency band and the tolerance value;

[0058] The eighth tolerance information includes an eighth correspondence between relative transmit power and tolerance value, wherein the relative transmit power includes the target relative transmit power;

[0059] The ninth tolerance information includes the ninth correspondence between the relative transmit power and the operating frequency range and the tolerance value.

[0060] The tenth tolerance information includes the tenth correspondence between the relative transmit power, the operating frequency band, and the tolerance value.

[0061] As previously stated, the tolerance value in this embodiment is the maximum difference between the terminal's indicated transmit power and the actual transmit power. This is because, given that the terminal's tolerance influence factor is uniquely determined, the terminal's tolerance can vary within a certain range. For example, when the terminal's operating frequency band is determined to be the FR1 band, and the absolute value of the target relative transmit power (or power change value) is 1dB, the terminal's tolerance value may be any value between 0dB and 5dB. To ensure that the power control RF error, i.e., the tolerance, during actual power control of the terminal does not cause the TPC command to fail, this embodiment uses the maximum difference between the terminal's indicated transmit power and the actual transmit power as a reference factor to adjust the target relative transmit power. If the TPC command will not fail when the terminal exhibits the maximum tolerance, then the TPC command will certainly not fail when the terminal exhibits a tolerance smaller than the maximum tolerance. If the terminal's maximum tolerance is not used as a reference factor to adjust the target relative transmit power, then the TPC command may fail when the terminal exhibits the maximum tolerance.

[0062] To facilitate understanding, the following example, using the TPC command as the second method, illustrates the relationship between the tolerance value and the terminal's operating frequency band and relative transmit power, taking the operating frequency band and relative transmit power in the TPC command as examples. Refer to Tables 1 and 2. Table 1 shows the relationship between the power variation value in the relative transmit power and the terminal's tolerance value under the FR1 frequency band. Table 2 shows the relationship between the power variation value in the relative transmit power and the terminal's tolerance value under the FR2 frequency band. In Table 1, Pint ≥ P ≥ minimum transmit power; in Table 2, maximum transmit power ≥ P > Pint.

[0068] Step 202: Send a transmit power control (TPC) command to the terminal based on the power control tolerance information. The TPC command is used to indicate the uplink transmit power of the terminal.

[0069] In practice, the target tolerance value can be determined based on the power control tolerance information. The method for determining the target tolerance value can be shown in the following example.

[0070] Example 1: The terminal can send the correspondence between all possible tolerance values ​​and tolerance influencing factors to the network-side device. The network-side device can then search for and determine the target tolerance value from all the received correspondences based on at least one of the terminal's current operating frequency band, operating frequency, transmit power, relative transmit power, and the TPC command method.

[0071] Example 2: To facilitate searching, the terminal and network-side devices can pre-store the correspondence between all possible tolerance values ​​and tolerance influencing factors of the terminal, and establish an index value for the correspondence. The terminal determines the index value of the correspondence between at least one of the terminal's current operating frequency band, operating frequency, transmit power, and relative transmit power, as well as the method of the TPC command, and sends the index value of the correspondence to the network-side device. The network-side device then searches for and determines the target tolerance value based on the received index value.

[0072] Example 3: The terminal can also determine the target tolerance value based on at least one of the terminal's current operating frequency band, operating frequency, transmit power, relative transmit power, and TPC command method, and send the target tolerance value to the network side device.

[0073] The terminal can compare the target tolerance value with the power change value in the target relative transmit power. When the target tolerance value is less than the power change value in the target relative transmit power, the terminal sends a first notification message to the network-side device to notify the network-side device that the target tolerance value is less than the power change value in the target relative transmit power. When the target tolerance value is greater than or equal to the power change value in the target relative transmit power, the terminal sends a second notification message to the network-side device to notify the network-side device that the target tolerance value is greater than or equal to the power change value in the target relative transmit power.

[0074] After determining the target tolerance value, the target relative transmit power in the target relative transmit power can be compared with the target tolerance value first, and then the TPC command can be determined based on the comparison result and the second information. Alternatively, the comparison result between the target relative transmit power and the target tolerance value in the target relative transmit power can be obtained directly by reading the first notification information and the second notification information sent by the terminal to the network-side equipment, and the TPC command can be determined based on the comparison result and the second information.

[0075] For example, when the target tolerance value is less than the power change value in the target relative transmit power, the second information may include the target received power target1, the current received power Rx1 of the network-side device, the RF received dynamic range, and the in-channel selectivity (ICS). The RF received dynamic range refers to the difference between the maximum and minimum power simultaneously received by the network-side device, and the ICS refers to the difference in received signal power between different RBs allowed by the network-side device.

[0076] First, the network-side device can determine the maximum uplink receiving power Th1 of the network-side device according to the pre-set reference sensitivity, i.e., the minimum power value that the network-side device can receive, the radio frequency receiving dynamic range, and the ICS. Then, according to the target tolerance Tolerance1, the target receiving power target1, the current receiving power Rx1 of the network-side device, and the maximum uplink receiving power Th1, the power change value that meets the preset conditions is determined as the target power change value X, and it is determined that the TPC command includes the target power change value. When X is a positive number, it means that the terminal should increase the power; when X is a negative number, it means that the terminal should decrease the power.

[0077] Among them, the preset conditions can be Rx1 + Tolerance 1 + X < Th1 and target 1 is within [Rx1 - Tolerance1 + X, Rx1 + Tolerance 1 + X]. Further, Tolerance1 can be modeled according to the preset conditions to judge the optimal actual Tolerance1 or directly determine X according to Tolerance1 / -Tolerance1.

[0078] The terminal can adjust the transmission power of the terminal according to the target power change value in the TPC command. When the target power change value is a positive number, the terminal increases the power; when X is a negative number, the terminal decreases the power. The absolute value of the target power change value is the change value of the transmission power of the terminal. Example 1: When X is +5dB, the terminal increases the power by 5dB based on the current transmission power and uses the power after increasing by 5dB as the transmission power. Example 2: When X is -3dB, the terminal decreases the power by 3dB based on the current transmission power and uses the power after decreasing by 3dB as the transmission power.

[0079] In the embodiment of the present application, by receiving the power control tolerance information sent by the terminal and determining the TPC command according to the power control tolerance information to indicate the uplink transmission power of the terminal. The TPC command can be determined on the premise of considering the tolerance of the terminal, i.e., the power control radio frequency error, so that the TPC command will not fail due to the power control radio frequency error of the terminal, thereby solving the problem that the existing TPC command fails due to the power control radio frequency error of the terminal.

[0080] Optionally, when the TPC command is in the first mode, sending the transmit power control TPC command to the terminal based on the power control tolerance information includes: when the power control tolerance information includes the target tolerance value, sending the transmit power control TPC command to the terminal based on the target tolerance value;

[0081] Alternatively, if the power control tolerance information includes at least one of the first tolerance information to the fifth tolerance information, the target tolerance value is determined based on the first information and at least one of the first tolerance information to the fifth tolerance information, and a transmit power control (TPC) command is sent to the terminal based on the target tolerance value.

[0082] As described above, the first information includes at least one of the terminal's current operating frequency, target transmit power, and target relative transmit power. Specifically, determining the target tolerance value based on the first information and at least one of the first to fifth tolerance information may include at least one of the following:

[0083] The tolerance value corresponding to the current operating frequency of the terminal in the first correspondence is determined as the target tolerance value;

[0084] Alternatively, the current operating frequency band of the terminal can be determined based on the current operating frequency of the terminal, and then the tolerance value corresponding to the current operating frequency band of the terminal in the second correspondence relationship can be determined as the target tolerance value.

[0085] Alternatively, the tolerance value corresponding to the target transmission power in the third correspondence relationship can be determined as the target tolerance value;

[0086] Alternatively, the tolerance value corresponding to the current operating frequency of the terminal and the target transmit power in the fourth correspondence relationship can be determined as the target tolerance value;

[0087] Alternatively, the current operating frequency band of the terminal can be determined based on the terminal's current operating frequency, and then the tolerance value corresponding to the terminal's current operating frequency band and the target transmit power in the fifth correspondence relationship can be determined as the target tolerance value.

[0088] When the TPC command is in the second mode, sending a transmit power control TPC command to the terminal based on the power control tolerance information includes:

[0089] If the power control tolerance information includes the target tolerance value, a transmit power control (TPC) command is sent to the terminal based on the target tolerance value.

[0090] Alternatively, if the power control tolerance information includes at least one of the sixth to tenth tolerance information, the target tolerance value is determined based on the first information and at least one of the sixth to tenth tolerance information, and a transmit power control (TPC) command is sent to the terminal based on the target tolerance value.

[0091] In specific implementation, the target tolerance value is determined based on at least one of the first information and the sixth to tenth tolerance information, including at least one of the following:

[0092] The tolerance value corresponding to the current operating frequency of the terminal in the sixth correspondence is determined as the target tolerance value;

[0093] Alternatively, the current operating frequency band of the terminal can be determined based on the terminal's current operating frequency, and then the tolerance value corresponding to the terminal's current operating frequency band in the seventh correspondence relationship can be determined as the target tolerance value.

[0094] Alternatively, the tolerance value corresponding to the target's relative transmission power in the eighth correspondence relationship can be determined as the target tolerance value;

[0095] Alternatively, the tolerance value corresponding to the current operating frequency of the terminal and the target relative transmission power in the ninth correspondence relationship can be determined as the target tolerance value;

[0096] Alternatively, the current operating frequency band of the terminal can be determined based on the terminal's current operating frequency, and then the tolerance value corresponding to the terminal's current operating frequency band and the target relative transmit power in the tenth correspondence can be determined as the target tolerance value.

[0097] Optionally, sending a transmit power control (TPC) command to the terminal based on the target tolerance value includes:

[0098] The TPC command is determined based on the second information obtained by the network-side device, the target relative transmit power, and the target tolerance value;

[0099] Send the TPC command to the terminal.

[0100] In practice, the second information includes at least one of the following:

[0101] The dynamic range of radio frequency reception of network equipment;

[0102] In-channel selective communication (ICS) for network devices;

[0103] Path loss.

[0104] Optionally, determining the TPC command based on the second information obtained by the network-side device, the target relative transmit power, and the target tolerance value includes:

[0105] The target relative transmit power is compared with the target tolerance value to obtain a first comparison result;

[0106] The TPC command is determined based on the first comparison result and the second information.

[0107] For specific implementation details, please refer to [link / reference]. Figure 4 If the target tolerance value is less than the target relative transmit power, it means that the TPC command can control the transmit power of the terminal. Based on the first comparison result and the second information, the target power change value in the TPC command can be determined, and the terminal can be instructed to adjust the transmit power according to the target power change value in the TPC command.

[0108] When the target tolerance value is greater than or equal to the target relative transmit power, it indicates that adjusting the terminal's transmit power via the target power change value in the TPC command is no longer effective in controlling the terminal's transmit power. Regardless of the target power change value set, because the target tolerance value is greater than or equal to the target relative transmit power, adjusting the transmit power based on the target power change value in the TPC command may cause the TPC command to malfunction. For example, if the terminal's current transmit power is 5dB and the target transmit power is 10dB, then the target relative transmit power is 5dB. If the target tolerance value is 10dB and the target power change value is set to 1dB, considering the target tolerance value, the actual power adjustment range of the terminal is -9dB to +11dB. This means that the TPC command may require the terminal to increase the power by 1dB, but the terminal may actually decrease it by -9dB. In this case, the TPC command can be set to instruct the terminal to send information at the maximum transmit power. Due to the terminal's inherent characteristics, when the terminal sends information at the maximum transmit power, the target tolerance value will always be negative, thus preventing the TPC command from requiring an increase in the terminal's transmit power while actually reducing the terminal's transmit power.

[0109] By comparing the target relative transmit power with the target tolerance value, a first comparison result is obtained. Based on the first comparison result and the second information, a TPC command is determined. A reasonable TPC command can be determined based on the first comparison result, avoiding the situation where the TPC command fails due to adjusting the terminal transmit power by the target power change value in the TPC command when the target tolerance value is greater than or equal to the target relative transmit power. This solves the problem of existing TPC command failure caused by power control radio frequency errors in the terminal.

[0110] Optionally, the second information includes radio frequency reception dynamic range and in-channel selectivity (ICS);

[0111] Determining the TPC command based on the first comparison result and the second information includes:

[0112] Based on the radio frequency reception dynamic range and the ICS, a first threshold is determined, wherein the first threshold is the maximum uplink reception power of the terminal allowed by the network-side device.

[0113] In practice, the process of determining the maximum uplink receiving power of the terminal allowed by the network-side device, i.e., the first threshold, based on the dynamic range of radio frequency reception and ICS is common knowledge and will not be elaborated here.

[0114] Alternatively, a second threshold may be determined based on the radio frequency reception dynamic range, the ICS, and the path loss, wherein the second threshold is the maximum uplink transmit power of the terminal allowed by the network-side device.

[0115] In practical implementation, the sum of the first threshold and the path loss can be determined as the terminal's maximum uplink transmit power, i.e., the second threshold. Path loss refers to the loss caused by the propagation of radio waves in space, which is caused by the radiation and diffusion of transmit power and the propagation characteristics of the channel, reflecting the variation of the average received signal power over a macroscopic range. Theoretically, it is assumed that the path loss is the same for the same transmit and receive distance. In the embodiments of this application, the path loss can be determined as follows: First, the terminal sends a reference power to the network-side device; then, the network-side device measures the actual received power; finally, the actual received power is subtracted from the reference power to obtain the difference, which is the path loss.

[0116] The TPC command is determined based on the first comparison result and the first threshold, or based on the first comparison result and the second threshold.

[0117] See Figure 4 As mentioned above, if the first comparison result is that the target tolerance value is less than the target relative transmit power, it means that the TPC command can control the transmit power of the terminal. The target change value in the TPC command can be determined according to the first comparison result and the first threshold, and the terminal can be instructed to adjust the transmit power according to the target change value in the TPC command.

[0118] Optionally, the second information further includes the target received power; determining the TPC command based on the first comparison result and the first threshold includes:

[0119] If the target tolerance value is less than the target relative transmit power, it is determined that the TPC command includes a target power change value, wherein the target power change value is a power change value that satisfies a first preset condition;

[0120] The first preset condition includes: the sum of the first power value, the target tolerance value, and the target power change value is less than the first threshold; the target received power is greater than the starting point value and less than the ending point value, the first power value is the power of the terminal received by the current network-side device, the starting point value is the difference between the sum of the first power value and the target power change value and the target tolerance value, and the ending point value is the sum of the sum of the first power value and the target power change value and the target tolerance value.

[0121] If the first comparison result shows that the target tolerance value is greater than or equal to the target relative transmit power, it indicates that adjusting the terminal's transmit power through the target power change value in the TPC command is no longer effective in controlling the terminal's transmit power. In this case, the terminal can be instructed to transmit at an appropriate transmit power via a TPC command, as follows.

[0122] Optionally, see Figure 4 The step of determining the TPC command based on the first comparison result and the first threshold includes:

[0123] When the target tolerance value is greater than or equal to the target relative transmit power, the maximum receive power is determined based on the terminal's maximum transmit power and path loss. The maximum receive power is the power received by the network-side device when the terminal transmits at its maximum transmit power. Specifically, the maximum receive power is the difference between the maximum transmit power and the path loss.

[0124] The maximum received power is compared with the first threshold to obtain a second comparison result;

[0125] The TPC command is determined based on the second comparison result.

[0126] If the second comparison result shows that the maximum received power is less than the first threshold, the maximum transmitted power is determined as the first target transmitted power;

[0127] The TPC command is determined based on the first target transmit power, and the TPC command includes indication information for instructing the terminal to transmit at the first target transmit power.

[0128] If the second comparison result indicates that the maximum received power is greater than or equal to the first threshold, the TPC command is determined based on the first threshold and path loss. The TPC command includes indication information instructing the terminal to transmit at a second target transmit power, where the second target transmit power is the sum of the first threshold and the path loss. It should be understood that when the terminal transmits at the second target transmit power, the power received by the network-side device is equal to the first threshold.

[0129] In addition to the above-mentioned implementation method of determining the TPC command based on the first comparison result and the first threshold, this application embodiment also provides an implementation method of determining the TPC command based on the first comparison result and the second threshold, as follows.

[0130] Optionally, determining the TPC command based on the first comparison result and the second threshold includes:

[0131] If the target tolerance value is less than the target relative transmit power, it indicates that the TPC command can control the terminal's transmit power, determine the target power change value in the TPC command, and instruct the terminal to adjust its transmit power according to the target power change value in the TPC command. Specifically, the power change value that satisfies the second preset condition is determined as the target power change value in the TPC command. The second preset condition includes: the sum of the second power value, the target tolerance value, and the target power change value is less than a second threshold; the target output power is greater than or equal to a first value and less than or equal to a second value. The first value is the difference between the second threshold, the sum of the target power change value, and the target tolerance value; the second value is the sum of the second threshold, the target power change value, and the target tolerance value; and the second power value is the terminal's current transmit power value. The target output power can be determined based on the target received power and path loss, i.e., the target output power is the sum of the target received power and the path loss.

[0132] Optionally, determining the TPC command based on the first comparison result and the second threshold includes:

[0133] If the target tolerance value is greater than or equal to the target relative transmit power, it indicates that adjusting the terminal transmit power through the target power change value in the TPC command is no longer effective in controlling the terminal's transmit power. To avoid TPC command failure, this embodiment compares the terminal's maximum transmit power with the second threshold to obtain a third comparison result.

[0134] The TPC command is determined based on the third comparison result.

[0135] If the third comparison result shows that the maximum transmission power is less than the second threshold, the maximum transmission power is determined as the third target transmission power;

[0136] The TPC command is determined based on the third target transmit power, and the TPC command includes indication information for instructing the terminal to transmit at the third target transmit power.

[0137] If the third comparison result is that the maximum transmission power is greater than or equal to the second threshold, the power corresponding to the second threshold is determined as the fourth target transmission power;

[0138] The TPC command is determined based on the fourth target transmit power, and the TPC command includes indication information for instructing the terminal to transmit at the fourth target transmit power.

[0139] See Figure 3 , Figure 3 This is the second schematic flowchart of the power control method provided in the embodiments of this application. Figure 3The power control method shown can be executed by the terminal.

[0140] like Figure 3 As shown, the power control method may include the following steps:

[0141] Step 301: Send power control tolerance information to the network-side device;

[0142] Step 302: Receive the TPC command sent by the network-side device;

[0143] Step 303: Adjust the transmit power according to the TPC command, or transmit at the power indicated by the TPC command.

[0144] It should be noted that this embodiment is used as a reference for... Figure 2 The implementation method of the terminal corresponding to the method embodiment can be found in the following examples. Figure 2 The relevant descriptions in the method embodiments can achieve the same beneficial effects. To avoid repetition, they will not be repeated here.

[0145] It should also be noted that the TPC command is determined based on the power control tolerance information executed by the network-side device. Alternatively, the network-side device can send the first information and the second information obtained by the network-side device to the terminal, and the terminal can determine the TPC command by combining the power control tolerance information. The process of the terminal determining the TPC command based on the above information is the same as that of the network-side device, and will not be described again here.

[0146] For ease of understanding, see Figure 5 and Figure 6 The following is an example:

[0147] Power control performed by the base station

[0148] 1. The terminal reports the maximum allowed power control radio frequency tolerance information to the base station.

[0149] 1.1 This information includes one or more of the following:

[0150] 1.1.1 The frequency band range corresponding to this information (e.g., FR1, FR2)

[0151] 1.1.2 Is the maximum tolerance greater than the corresponding TPC command indication? An example of a tolerance greater than the TPC command is that the base station requests a 3dB boost from the TPC, but the actual terminal's signal drops by 1dB after passing through the RF device. In this case, the tolerance is 3 - (-1) = 4dB. Since the 4dB tolerance is greater than the TPC command, this indication is set to 1; otherwise, it is set to 0.

[0152] 1.1.3 Predefined correspondences between various TPC commands and maximum tolerances; the terminal reports the corresponding index value.

[0153] 1.1.4 Corresponding relationship between the TPC commands reported by the terminal and the maximum tolerance, for example, the tolerance value reported for each TPC command or each range of TPC commands

[0154] 2 The base station adjusts the uplink power of the terminal according to the maximum power control radio tolerance information reported by the terminal received and the radio receiving dynamic range of the base station, ICS, and the maximum input signal. The radio receiver dynamic range refers to the difference between the maximum power and the minimum power received simultaneously. The ICS (in-channel selectivity) index refers to the allowable difference in received signal power between different RBs. The specific scheme includes

[0155] 2.1 If the terminal tolerance is less than the corresponding TPC command, the base station determines the TPC command for the terminal according to the current radio receiving dynamic range, ICS, and maximum input power of the base station. In addition, the uplink power control radio tolerance of the terminal needs to be fully considered

[0156] 2.1.1 If the maximum uplink receiving power of the terminal allowed by the base station at this time judged according to the radio receiving dynamic range, ICS, and maximum input power is Th1, the terminal tolerance is Tolerance 1, and the power of the terminal received by the current base station is Rx1. At this time, Rx1 < Th1, the base station judges the target receiving power as target 1, and the target TPC command judged by the base station is X (X being positive means increasing power, X being negative means decreasing power). Then the adjustment criterion for X is Rx1 + Tolerance 1 + X < Th1 and target1 is within [Rx1 - Tolerance1 + X, Rx1 + Tolerance 1 + X]. Under this principle, tolerance can be modeled to judge the optimal actual tolerance or directly determine X according to tolerance1 / -tolerance1

[0157] 2.2 If the terminal tolerance is greater than the corresponding TPC command, it means that the power change of the actual radio device is uncontrollable at this time. For example, when the TPC command instructs the terminal to increase power, due to radio frequency errors, the terminal actually decreases power. The base station guides the terminal to transmit at the maximum transmit power according to the current radio receiving dynamic range, ICS, maximum input power judgment of the base station, and the Pcmax value reported by the terminal

[0158] 2.2.1 If the maximum uplink receiving power of the terminal allowed by the base station at this time judged according to the radio receiving dynamic range, ICS, and maximum input power is Th1, and the receiving power corresponding to the terminal transmitting at Pcmax calculated by the base station is Rx2 (without considering tolerance),

[0159] 2.2.1.1 If RX2 < Th1, the base station requires the terminal to transmit at the maximum transmit power Pcmax

[0160] 2.2.1.2 If RX2 >= Th1, then the base station requires the terminal to transmit at the transmit power corresponding to Th1. In this case, calculating the transmit power corresponding to Th1 only requires considering path loss, and does not need to consider RF power tolerance.

[0161] 2.2.1.3 In summary, the terminal transmits at the transmit power corresponding to min(Rx2,Th1).

[0162] Terminal-autonomous power control

[0163] 1. Maximum power control radio frequency tolerance information of the terminal evaluation computing device

[0164] 1.1 It is necessary to calculate one or more of the following information.

[0165] 1.1.1 Corresponding frequency band range (e.g., FR1, FR2)

[0166] 1.1.2 Is the maximum tolerance greater than the corresponding TPC command indication? An example of a tolerance greater than the TPC command is that the network requires a 3dB boost in TPC, but the signal actually drops by 1dB after passing through the RF device. In this case, the tolerance is 3 - (-1) = 4dB. Since the tolerance of 4dB is greater than the TPC command, this indication is set to 1; otherwise, it is set to 0.

[0167] 1.1.3 Predefined correspondences between various TPC commands and maximum tolerances, and the index values ​​of the correspondences supported by the terminal device.

[0168] 1.1.4 The terminal supports the correspondence between TPC commands and maximum tolerances, such as the tolerance value for each TPC command or each range of TPC commands.

[0169] 2. The base station sends a message to the terminal, determining the maximum uplink transmit power allowed by the base station at this time as Th2, based on the RF receive dynamic range, ICS, and maximum input power. This threshold can be included in existing TPC commands and sent to the terminal together, with specific signaling methods including RRC, MAC CE, and DCI indication signaling.

[0170] 3. Based on the base station's TPC command and the Th2 threshold therein, the terminal reasonably determines the actual uplink target transmit power.

[0171] 3.1 If the terminal tolerance is less than the corresponding TPC command, the terminal determines the actual target output power based on Th2 and the terminal's uplink power control RF tolerance.

[0172] 3.1.1 If the terminal tolerance is Tolerance 2, the current terminal transmit power is Tx2 (without considering RF error), and the TPC command indicated by the base station is X2 (X2 being positive indicates power increase, and X2 being negative indicates power decrease), then the adjustment criterion for X2 is Tx2 + Tolerance 2 + X2 < Th2 and the target actual output power is within [Tx2 - Tolerance 2 + X2, Tx1 + Tolerance2 + X2]. Under this principle, the base station can model the tolerance according to the actual tolerance value to select the optimal tolerance to determine the value of X2 or select the X2 corresponding to the maximum tolerance 2 / -tolerance 2

[0173] 3.2 If the terminal tolerance is greater than the corresponding TPC command, the terminal decides to transmit at the maximum transmit power as much as possible according to Th2 and the terminal uplink power control RF tolerance

[0174] 3.2.1 If the terminal tolerance is Tolerance 2, the current terminal transmit power is Tx2 (without considering RF error), and the TPC command indicated by the base station is X2 (X2 being positive indicates power increase, and X2 being negative indicates power decrease),

[0175] 3.2.1.1 If Pcmax < Th2, the terminal transmits at the maximum transmit power

[0176] 3.2.1.2 If Pcmax >= Th2, the terminal transmits at the transmit power corresponding to Th2
