This application claims the priority of the Chinese Patent Application filed on August 10, 2017, the Chinese Patent Office, Application No. 201710682011.6, entitled "Power Control Method and Base Station of a Physical Uplink Control Channel PUCCH", the entire contents of which are The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a power control method and a base station of a PUCCH.

Background technique

As the demand for mobile communication services changes, organizations such as the International Telecommunication Union (ITU) and 3GPP (3rd Generation Partnership Project) are beginning to research new wireless communication systems (for example, the fifth 5 Generation New Radio Access Technology (5G NR)).

In a Long Term Evolution (LTE) wireless communication system, a base station generally adjusts power of a user terminal by using closed loop power control, and the base station feeds back power control information to the UE according to a measurement result of an uplink of a user equipment (User Equipment, UE). The uplink transmit power obtained by the UE through the open loop power control is adjusted, so that the transmit power of the UE can be controlled more accurately.

The main principle of closed-loop power control is based on the measurement of the received quality of the signal. For example, the Cycllic Redundancy Check (CRC) can be used to determine the BLER to determine whether the closed-loop power control meets the target block error rate (Block Error Rate). , BLER). For closed-loop power control of a Physical Uplink Share Channel (PUSCH), the CRC can obtain signal quality through the received PUSCH transport block. If the measured BLER of the PUSCH is lower than the Quality of Service (QoS) threshold, the terminal sends a positive TPC command to increase the transmit power, and vice versa, sends a negative Transmission Power Control (TPC) command. Reduce the transmit power. For the power control of the PUCCH, if there is no CRC check information, the evolved Node B (eNB) can use the average received signal and the interference to noise ratio (SINR) as the reception quality reference. information. If the measured average received SINR is lower than the target SINR, a positive TPC command is sent to the terminal to increase the transmit power, and conversely a negative TPC command is sent to reduce the transmit power.

However, in the future 5G network construction, there is no specific solution for how to perform uplink power control for uplink PUCCH transmission. A single PUCCH reception quality determination method is used in LTE. However, in the NR system, different uplink coding information (Uplink Control Information, UCI) in the PUCCH will adopt different coding modes, corresponding to different transmission performances. If the method in LTE is still used, the PUCCH power control will not be performed very accurately, resulting in a decrease in channel transmission performance.

Summary of the invention

In the NR system, UCIs containing different numbers of bits will use different coding methods. For example, when the number of UCI bits is 1, a repetitive coding scheme is adopted; when the number of UCI bits is 2, a simple coding scheme is adopted; when the number of UCI bits is greater than 2 and less than or equal to 11, a Reed-Muller code is used ( Reed-Muller, RM) coding scheme; when the UCI bit number is greater than 11, the polarization polar () coding scheme is adopted, and further, when the polar coding scheme is adopted, the UCI bit number is less than or equal to 22 and greater than 22 bits may be adopted. Different CRC check code lengths. Based on the above information, we can define different PUCCH reception quality determination methods.

In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings and specific embodiments.

Referring to FIG. 1, a first embodiment of the present invention provides a power control method for a physical uplink control channel PUCCH, including:

S101. Obtain a number of bits of uplink control information UCI transmitted in the PUCCH.

S102. Control, according to the number of bits of the UCI, a transmit power when the terminal transmits an uplink signal in the PUCCH.

Specifically, in step S101, the number of bits of the current uplink control information UCI transmitted in the PUCCH is first obtained.

For the step S102, the transmission power when the terminal transmits the uplink signal in the PUCCH may be controlled according to the preset range in which the number of bits of the UCI is located, where the preset range is encoded according to the UCI used by the different number of bits. Divide. For example, the preset range in which the UCI of the different bit number is located may be divided according to the coding mode adopted by the UCI of different bit numbers; according to the obtained number of bits of the UCI and the preset range in which the UCI is located, the control terminal is in the Transmit power when the uplink signal is transmitted in the PUCCH. Further, for different preset ranges, the terminal may be controlled to adopt different transmit powers when transmitting uplink signals in the PUCCH.

The preset range may be divided into [greater than the first preset value, less than or equal to the first preset value] according to the foregoing division manner, and further, according to actual needs, the range larger than the first preset value may be further divided into [ greater than The first preset value is less than or equal to the second preset value, which is greater than the second preset value, and may further divide the less than or equal to the first preset value into [equal to any value in the third preset value set, The first preset value is, for example, 11 , the second preset value is 22, and the third preset value set is, for example, { 1,2}. Step S102 may specifically include the following implementation manners (for example only, and is not limited to step S102):

Mode 1, corresponding to [greater than the first preset value] in the preset range:

When the number of bits of the UCI is greater than the first preset value, the detection block error rate BLER of the PUCCH transmission is obtained based on the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI;

Transmitting control information for reducing a transmission power of the terminal to control a transmission power when the terminal transmits an uplink signal in the PUCCH, when the detection BLER is lower than a target BLER;

When the detected BLER is higher than the target BLER, control information for characterizing the transmission power of the terminal is transmitted to control a transmission power when the terminal transmits an uplink signal in the PUCCH.

When the number of bits of the UCI is greater than the first preset value, the detection block error rate BLER of the PUCCH transmission is obtained based on the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI. The specific implementation may include the following two types:

Mode 1A, corresponding to [greater than the first preset value] in the preset range:

When the number of bits of the UCI is greater than the first preset value, based on the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI, obtaining the number of bits transmitted in the PUCCH is greater than the first preset. The value of UCI is detected by the block error rate BLER.

In the mode 1B, corresponding to the preset range is greater than the first preset value and less than or equal to the second preset value, greater than the second preset value:

When the number of bits of the UCI is greater than a first preset value and less than or equal to a second preset value, obtaining, according to the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI, obtaining the transmission in the PUCCH a detection block error rate BLER of the UCI whose number of bits is greater than the first preset value and less than or equal to the second preset value;

When the number of bits of the UCI is greater than the second preset value, based on the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI, obtaining the number of bits transmitted in the PUCCH is greater than the second The UCI detection error block rate BLER of the preset value.

For example, according to the coding mode adopted by the UCI of different bit numbers, the preset range in which the UCI of the different bit number is located is divided; according to the number of bits of the UCI obtained in step S101 and the preset range in which the UCI is located, the control is performed. Transmit power when the terminal transmits an uplink signal in the PUCCH.

In mode 1, the first preset value is set to 11. When the number of UCI bits transmitted in the PUCCH is greater than 11, the BLER is determined based on the check information of the CRC of the polar code, and then according to the detected BLER and the target BLER. The difference determines the TCC information for closed loop adjustment. When the detected BLER is higher than the target BLER, a positive TPC command is sent to increase the terminal transmit power; when the detected BLER is lower than the target BLER, a negative TPC command is sent to reduce the transmit power.

For mode 1A, a BLER is calculated for a PUCCH transmission with a UCI greater than 11 bits, and compared with a corresponding target BLER to determine TPC information.

The target BLER used when the number of UCI bits transmitted in the PUCCH is greater than 22 is the same as the target BLER used when the number of UCI bits transmitted in the PUCCH is less than or equal to 22.

For mode 1B, setting a second preset value of 22, when the number of UCI bits transmitted in the PUCCH is greater than 22, the target BLER used and the number of UCI bits transmitted in the PUCCH being less than or equal to 22 are different;

At this time, the detected BLER will be separately counted according to the number of UCI bits transmitted in the PUCCH, that is, when the number of UCI bits transmitted in the PUCCH is greater than 22, a BLER_A is calculated, corresponding to the target BLER_H; when the number of UCI bits transmitted in the PUCCH is less than Or equal to 22 and greater than 11, a BLER_B is counted, corresponding to the target BLER_L. The BLER_A is compared with the corresponding target BLER_H to determine the TPC information, and the BLER_B and the corresponding target BLER_L are compared to determine the TPC information.

Mode 2, corresponding to [less than or equal to the first preset value] in the preset range:

When the number of bits of the UCI is less than or equal to a first preset value, detecting an average signal to interference and noise ratio SINR of the PUCCH transmission;

Transmitting control information for degrading a transmit power of the terminal to control a transmit power when the terminal transmits an uplink signal in the PUCCH, when the average SINR is higher than a target SINR;

When the average SINR is lower than the target SINR, control information for characterizing the transmission power of the terminal is transmitted to control a transmission power when the terminal transmits an uplink signal in the PUCCH.

The specific implementation manner of detecting the average signal and the interference and noise ratio SINR of the PUCCH transmission may include the following two types when the number of bits of the UCI is less than or equal to the first preset value:

Mode 2A, corresponding to [less than or equal to the first preset value] in the preset range:

When the number of bits of the UCI is less than or equal to a first preset value, detecting that the number of bits transmitted in the PUCCH is less than or equal to an average SINR of the UCI of the first preset value. The target SINR may be artificially set, or equal to a sum of a fourth preset value and an offset value.

When the target SINR is equal to the sum of the fourth preset value and an offset value, the fourth preset value is that the PUCCH is detected when the number of bits of the UCI is greater than the first preset value. The number of bits transmitted is greater than the average SINR of the UCI of the first preset value; the offset value is equal to the target SINR and the detected number when the number of bits of the UCI is greater than a first preset value The number of bits transmitted in the PUCCH is greater than the difference in the target SINR of the UCI of the first preset value; or

The fourth preset value is an average SINR of the detected physical uplink shared channel PUSCH; the offset value is equal to a difference between the target SINR and a target SINR of the PUSCH.

In the mode 2B, corresponding to any value in the third preset value set in the preset range, greater than the maximum value in the third preset value set and smaller than the first preset value:

When the number of bits of the UCI is equal to any value in the third preset value set, detecting that the number of bits transmitted in the PUCCH is equal to the average SINR of the UCI of the any one of the third preset value sets, where The maximum value of the third preset value set is smaller than the first preset value.

When the number of bits of the UCI is greater than a maximum value of the third preset value set and less than or equal to the first preset value, detecting that the number of bits transmitted in the PUCCH is greater than the third preset value set The maximum value and less than or equal to the average SINR of the UCI of the first preset value.

In mode 2, the first preset value is set to 11. When the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the closed-loop adjusted TPC information is determined based on the detected average SINR.

For mode 2A, specifically, when the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the same target SINR is used, and the detected average SINR is compared with the target SINR, and when the detected SINR is higher than the target SINR, the transmission is performed. a negative TPC command to reduce the transmit power; when the detected SINR is lower than the target SINR, a positive TPC command is sent to increase the terminal transmit power;

Alternatively, comparing the detected average SINR with the average detected SINR_X of the PUCCH when the number of transmitted UCI bits is greater than 11, assuming that the target SINR of the PUCCH when the transmitted UCI bit number is less than or equal to 11 and greater than 11 is OFFSET_X dB ( When the target SINR of the PUCCH when the number of UCI bits transmitted is less than or equal to 11 > the target SINR when the number of transmitted UCI bits is greater than 11, OFFSET_X is a positive value, otherwise it is a negative value), then when the detected SINR When SINR_X+OFFSET_X is exceeded, a negative TPC command is sent to reduce the transmit power; when the detected SINR is lower than SINR_X+OFFSET_X, a positive TPC command is sent to increase the terminal transmit power;

Or, comparing the detected average SINR with the average detected SINR_Y of the PUSCH, assuming that the PUCCH is different from the target SINR of the PUSCH by the OFFSET_Y dB when the number of UCI bits transmitted is less than or equal to 11 (when the number of UCI bits of the PUCCH transmitted is less than or equal to When the target SINR at 11 o'clock>the target SINR of the PUSCH, OFFSET_X is a positive value, otherwise it is a negative value), when the detected SINR is higher than SINR_Y+OFFSET_Y, a negative TPC command is sent to reduce the transmit power; when the detected SINR is detected Below SINR_Y+OFFSET_Y, a positive TPC command is sent to increase the terminal transmit power.

For mode 2B, set the third preset value set to {1, 2};

The target SINR used when the number of UCI bits transmitted in the PUCCH is 1 bit, the target SINR used when the number of UCI bits transmitted in the PUCCH is 2 bits, and the number of UCI bits transmitted in the PUCCH is greater than 2 and less than or equal to 11 The target SINR is different;

At this time, the detected average SINR is compared with the corresponding target SINR, which is obtained after averaging the multiple transmission measurements corresponding to the number of currently transmitted UCI bits, when the detected SINR is higher than the corresponding The target SINR sends a negative TPC command to reduce the transmit power; when the detected SINR is lower than the corresponding target SINR, a positive TPC command is sent to increase the terminal transmit power.

Mode 3, corresponding to [less than or equal to the first preset value] in the preset range:

Detecting a false detection probability of a positive acknowledgement ACK of the PUCCH transmission when the number of bits of the UCI is less than or equal to a first preset value;

Transmitting control information for reducing a transmission power of the terminal to control a transmission power when the terminal transmits an uplink signal in the PUCCH, when the detection false detection probability is lower than a target false detection probability;

When the detection false detection probability is higher than the target false detection probability, control information for characterizing the transmission power of the terminal is transmitted to control the transmission power when the terminal transmits the uplink signal in the PUCCH.

The detecting the false detection probability of the positive acknowledgment ACK of the PUCCH transmission may include the following two implementation manners when the number of bits of the UCI is less than or equal to the first preset value:

Mode 3A, corresponding to [less than or equal to the first preset value] in the preset range:

When the number of bits of the UCI is less than or equal to the first preset value, detecting a detection false detection probability that the number of bits transmitted in the PUCCH is less than or equal to the UCI of the first preset value.

In the mode 3B, corresponding to any value in the third preset value set in the preset range, greater than the maximum value in the third preset value set and smaller than the first preset value:

When the number of bits of the UCI is equal to any value in the third preset value set, detecting that the number of bits transmitted in the PUCCH is small is equal to the detection of the UCI of the third preset value set. a probability, wherein a maximum value of the third preset value set is smaller than the first preset value.

When the number of bits of the UCI is greater than a maximum value of the third preset value set and less than or equal to the first preset value, detecting that the number of bits transmitted in the PUCCH is greater than the third preset value set The detection false detection probability of the UCI of the maximum value and less than or equal to the first preset value.

For the specific implementation manner in the mode 3, the first preset value is also set to be 11 and the third preset value set is {1, 2}, and the implementation manner is similar to the implementation manner in the method 2, and details are not described herein again. .

The foregoing implementation manners in the step S102 may be implemented separately or in any combination without contradicting each other, for example, using the following combinations:

Combination of Mode 1A and Mode 2A, Combination of Mode 1B and Mode 2A, Combination of Mode 1A and Mode 2B, Combination of Mode 1B and Mode 2B, Combination of Mode 1A and Mode 3A, Combination of Mode 1B and Mode 3A, Mode 1A and Combination of Mode 3B, Combination of Mode 1B and Mode 3B. Alternatively, for mode 2B and mode 3B, the implementation manner in mode 2B may also be adopted when the preset range is [equal to any value in the third preset value set], and the preset range is [greater than the third preset value. The maximum value of the concentration and less than the first preset value] adopts the implementation manner in the mode 3B, and the like. This is merely an example and does not constitute an absolute limitation on the combination of the above modes.

In order to better understand the several implementation manners in the foregoing step S102, the following examples are illustrated:

For example, corresponding to the combined implementation of modes 1A and 2A, it is assumed that under certain bandwidth and transmission conditions, when the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the target SINR is -2 dB; the number of UCI bits transmitted in the PUCCH When it is greater than 11, the target BLER is 0.01, and the UCI feedback bit transmitted by the terminal changes in a range of sizes from 1 to 100 in a plurality of transmissions.

Then the base station can determine the PUCCH reception quality and adjust the TPC information based on the following manner:

When it is detected that the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the averaging is performed according to the SINR of the PUCCH transmission in which the current transmission and the previously detected UCI bit number is less than or equal to 11, if the average detected SINR result is less than -2 dB. Sending a TPC command to increase the transmit power of the terminal, otherwise sending a TPC command to reduce the transmit power of the terminal;

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 11, the BLER statistics are performed according to the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 11, and when the detected BLER is higher than 0.01, the positive TPC is sent. Command to increase the terminal transmit power; otherwise send a negative TPC command to reduce the transmit power.

Or, for example, corresponding to the combination of mode 1A and mode 2A, assuming that under the specific bandwidth and transmission conditions, when the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the target SINR is -2 dB; the number of UCI bits transmitted in the PUCCH When it is greater than 11, the target BLER is 0.01, and the corresponding target SINR is 3 dB; the UCI feedback bit transmitted by the terminal changes with different conditions in the range of sizes from 1 to 100 in multiple transmissions.

Then the base station can determine the PUCCH reception quality and adjust the TPC information based on the following manner:

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 11, the BLER statistics are performed according to the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 11, and when the detected BLER is higher than 0.01, the positive TPC is sent. The command is used to increase the terminal transmit power; otherwise, the negative TPC command is sent to reduce the transmit power; and the SINR_R is averaged according to the SINR of the PUCCH transmission with the UCI bit number greater than 11 detected before, and the obtained average SINR_R is used for transmission. a PUCCH of 11 bits or less is used as a reference;

When it is detected that the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the averaging is performed according to the SINR of the PUCCH transmission in which the current transmission and the previously detected UCI bit number is less than or equal to 11, if the obtained average detected SINR result is smaller than SINR_R- 5dB, the TPC command is sent to increase the transmit power of the terminal, otherwise the TPC command is sent to reduce the transmit power of the terminal.

Or for example, corresponding to the combination of the mode 1A and the mode 3A,

It is assumed that under certain bandwidth and transmission conditions, when the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the target ACK misdetection probability does not exceed 1%; when the number of UCI bits transmitted in the PUCCH is greater than 11, the target BLER is 0.01. The UCI feedback bits transmitted by the terminal vary over the range of sizes from 1 to 100 in multiple transmissions.

Then the base station can determine the PUCCH reception quality and adjust the TPC information based on the following manner:

When it is detected that the number of UCI bits transmitted in the PUCCH is less than or equal to 11, the PUCCH statistical ACK false detection probability according to the current transmission and the previously detected UCI bit number is less than or equal to 11, if the obtained ACK false detection probability exceeds 1%, Sending a TPC command to increase the transmit power of the terminal, otherwise sending a TPC command to reduce the transmit power of the terminal;

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 11, the BLER statistics are performed according to the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 11, and when the detected BLER is higher than 0.01, the positive TPC is sent. Command to increase the terminal transmit power; otherwise send a negative TPC command to reduce the transmit power.

Or, for example, corresponding to the combination of the mode 1B and the mode 3B, it is assumed that under the specific bandwidth and transmission conditions, when the number of UCI bits transmitted in the PUCCH is 1 and 2, the target ACK misdetection probability does not exceed 1%; when in the PUCCH When the number of transmitted UCI bits is greater than 2 and less than or equal to 11, the target SINR is -2 dB; when the number of UCI bits transmitted in the PUCCH is greater than 11 and less than or equal to 22, the target BLER is 0.005, and the number of UCI bits transmitted in the PUCCH is greater than At 22 o'clock, the target BLER is 0.008, and the UCI feedback bit transmitted by the terminal varies with different conditions in the range of sizes from 1 to 100 in multiple transmissions.

Then the base station can determine the PUCCH reception quality and adjust the TPC information based on the following manner:

When it is detected that the number of UCI bits transmitted in the PUCCH is 1 or 2, the ACK misdetection probability is respectively calculated according to the current transmission and the PUCCH transmission in which the number of UCI bits detected before is 1 or 2, if the obtained ACK misdetection probability exceeds 1%, the TPC command is sent to increase the transmission power of the terminal, otherwise the TPC command is sent to reduce the transmission power of the terminal;

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 2 and less than or equal to 11, the SINR is averaged according to the SINR of the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 2 and less than or equal to 11, if the average detection is obtained If the SINR result is less than -2 dB, the TPC command is sent to increase the transmit power of the terminal, otherwise the TPC command is sent to reduce the transmit power of the terminal;

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 11 and less than or equal to 22, BLER statistics are performed according to the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 11 and less than or equal to 22, when the detected BLER is high. At 0.005, a positive TPC command is sent to increase the terminal transmit power; when the detected BLER is less than 0.005, a negative TPC command is sent to reduce the transmit power;

When it is detected that the number of UCI bits transmitted in the PUCCH is greater than 22, the BLER statistics are performed according to the PUCCH transmission when the current transmission and the previously detected UCI bit number is greater than 22, and when the detected BLER is higher than 0.008, the positive TPC is sent. Command to increase terminal transmit power; when the detected BLER is below 0.008, send a negative TPC command to reduce transmit power.

The above example is not exhaustive. By adopting the implementation manner in this embodiment, the accuracy of the closed loop adjustment parameter can be improved, thereby ensuring the transmission performance of the PUCCH channel.

The control module 202 is configured to control, according to the number of bits of the UCI, a transmit power when the terminal transmits an uplink signal in the PUCCH.

The control module 202 is specifically configured to:

And controlling, according to a preset range in which the number of bits of the UCI is located, a transmit power when the uplink signal is transmitted by the terminal in the PUCCH, where the preset range is divided according to an encoding manner adopted by a UCI of different number of bits.

Further, the preset range in which the UCI of the different bit number is located may be divided according to the coding mode adopted by the UCI of different bit numbers; and the terminal is controlled according to the obtained number of bits of the UCI and the preset range in which the UCI is located. Transmit power when transmitting an uplink signal in the PUCCH. Further, for different preset ranges, the terminal may be controlled to adopt different transmit powers when transmitting uplink signals in the PUCCH.

The preset range may be divided into [greater than the first preset value, less than or equal to the first preset value] according to the foregoing division manner, and further, according to actual needs, the range larger than the first preset value may be further divided into [ greater than The first preset value is less than or equal to the second preset value, which is greater than the second preset value, and may further divide the less than or equal to the first preset value into [equal to any value in the third preset value set, The first preset value is, for example, 11 , the second preset value is 22, and the third preset value set is, for example, { 1,2}.

Based on the preset range, the control module 202 may specifically include the following implementation manners (for example only, and is not limited to the control module 202):

The first implementation manner, corresponding to [greater than the first preset value] in the preset range, the control module includes:

a first obtaining submodule, configured to: when the number of bits of the UCI is greater than a first preset value, obtain detection error of the PUCCH transmission based on verification information of a cyclic redundancy check CRC of an encoding mode adopted by the UCI Block rate BLER;

The value of UCI is detected by the block error rate BLER.

Or, when the number of bits of the UCI is greater than the first preset value and less than or equal to the second preset value, the check information of the cyclic redundancy check CRC of the coding mode adopted by the UCI is obtained in the PUCCH. The detected block error rate BLER of the UCI that is greater than the first preset value and less than or equal to the second preset value;

When the number of bits of the UCI is greater than the second preset value, based on the verification information of the cyclic redundancy check CRC of the coding mode adopted by the UCI, obtaining the number of bits transmitted in the PUCCH is greater than the second The UCI detection error block rate BLER of the preset value.

In this embodiment, the first preset value is set to be 11. When the number of UCI bits transmitted in the PUCCH is greater than 11, the BLER is determined based on the check information of the CRC encoded by the polar, and then according to the detected BLER and the target BLER. The difference determines the closed-loop adjusted TPC information. When the detected BLER is higher than the target BLER, a positive TPC command is sent to increase the terminal transmit power; when the detected BLER is lower than the target BLER, a negative TPC command is sent to reduce the transmit power.

In this manner, a BLER is counted for a PUCCH transmission having a UCI greater than 11 bits, and compared with a corresponding target BLER to determine TPC information.

The target BLER used when the number of UCI bits transmitted in the PUCCH is greater than 22 is the same as the target BLER used when the number of UCI bits transmitted in the PUCCH is less than or equal to 22.

Or in the manner, setting a second preset value of 22, when the number of UCI bits transmitted in the PUCCH is greater than 22, the target BLER used and the number of UCI bits transmitted in the PUCCH being less than or equal to 22 are different;

At this time, the detected BLER will be separately counted according to the number of UCI bits transmitted in the PUCCH, that is, when the number of UCI bits transmitted in the PUCCH is greater than 22, a BLER_A is calculated, corresponding to the target BLER_H; when the number of UCI bits transmitted in the PUCCH is less than Or equal to 22 and greater than 11, a BLER_B is counted, corresponding to the target BLER_L. The BLER_A is compared with the corresponding target BLER_H to determine the TPC information, and the BLER_B and the corresponding target BLER_L are compared to determine the TPC information.

And a fourth sending submodule, configured to: when the average SINR is lower than the target SINR, send control information for characterizing the transmit power of the terminal to control a transmit power when the terminal transmits an uplink signal in the PUCCH.

In this manner, the first detecting submodule is specifically configured to:

When the number of bits of the UCI is less than or equal to a first preset value, detecting that the number of bits transmitted in the PUCCH is less than or equal to an average SINR of the UCI of the first preset value. The target SINR may be artificially set, or equal to a sum of a fourth preset value and an offset value.

When the target SINR is equal to the sum of the fourth preset value and an offset value, the fourth preset value is that the PUCCH is detected when the number of bits of the UCI is greater than the first preset value. The number of bits transmitted is greater than the average SINR of the UCI of the first preset value; the offset value is equal to the target SINR and the detected number when the number of bits of the UCI is greater than a first preset value The number of bits transmitted in the PUCCH is greater than the difference in the target SINR of the UCI of the first preset value; or

Or, comparing the detected average SINR with the average detected SINR_Y of the PUSCH, assuming that the PUCCH is different from the target SINR of the PUSCH by the OFFSET_Y dB when the number of UCI bits transmitted is less than or equal to 11 (when the number of UCI bits of the PUCCH transmitted is less than or equal to When the target SINR at 11 o'clock>the target SINR of the PUSCH, OFFSET_X is a positive value, otherwise it is a negative value), when the detected SINR is higher than SINR_Y+OFFSET_Y, a negative TPC command is sent to reduce the transmit power; when the detected SINR is detected Below SINR_Y+OFFSET_Y, a positive TPC command is sent to increase the terminal transmit power.

Or in the manner, when [the value equal to any value in the third preset value set is greater than the maximum value in the third preset value set and less than the first preset value] in the corresponding preset range, The third preset value set is {1, 2};
