Description

Uplink power control method, device and storage medium

Technical field

The present invention relates to the field of wireless communication technology, and in particular to an uplink power control method, device and storage medium.

Background technique

With the continuous development of wireless communication technology, certain transmission conflicts often exist between different service resources.

Taking the 5th generation mobile communication (5G) technology as an example, the 5G system introduces two services: Ultra Reliable & Low Latency Communication (URLLC) and Enhanced Mobile Broadband (eMBB) For the scenario where URLLC and eMBB coexist, in order to realize the instant transmission of URLLC, there will be a transmission conflict between URLLC and eMBB, that is, URLLC may occupy resources already allocated to eMBB. Moreover, URLLC and eMBB will interfere with each other, thereby affecting the demodulation performance of URLLC and eMBB.

In order to deal with the transmission conflict problem, the transmission conflict can be alleviated by adjusting the transmission power.

However, in order to adjust the transmission power, the base station needs to transmit a type of indication information to the user terminal (User Equipment, UE) to achieve the purpose of adjusting the transmission power. However, none of the current solutions provide such kind of instruction information.

The solution of the present invention can effectively adjust the transmission power of the uplink channel by setting the power control indication information in the power control information of the uplink channel, and solves the technical problem that the adjustment of the power parameter cannot be indicated.

TPC (Transmit Power Control): Abbreviation for transmit power control.

DCI (Downlink Control Information): Abbreviation for Downlink Control Information.

Specifically, referring to Fig. 1, Fig. 1 is a schematic diagram of functional modules of an uplink power control device of the present invention. The uplink power control device may be a device that is independent of the user terminal and can perform data processing, and it may be carried on the user terminal in the form of hardware or software.

In this embodiment, the uplink power control device at least includes an output module 110, a first processor 120, a first memory 130, and a first communication module 140.

The first memory 130 stores a first operating system and an uplink power control program; the output module 110 may be a display screen, a speaker, etc., and the display screen may display relevant interface information of the user terminal. The first communication module 140 may include a mobile communication module.

Wherein, when the uplink power control program in the first memory 130 is executed by the processor, the following steps are implemented:

In this embodiment, the power control information of the uplink channel is acquired, and the power control indication information is parsed from the power control information; the transmit power of the uplink channel is adjusted through the power control indication information. Obviously, in this embodiment, by setting the power control indication information in the power control information of the uplink channel, the transmission power of the uplink channel can be effectively adjusted, and the technical problem that the adjustment of the power parameter cannot be instructed is solved.

Based on the foregoing device architecture, a method embodiment of the present invention is proposed.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of an exemplary embodiment of an uplink power control method of the present invention. In this embodiment, the uplink power control method includes the following steps:

Step S10: Obtain the power control information of the uplink channel, and parse the power control indication information from the power control information.

It is understandable that the execution subject of this embodiment may be an uplink power control device, and the uplink power control device may be a user terminal. Specifically, the user terminal may be other electronic devices with communication functions such as mobile phones.

In a specific implementation, in order to adjust power parameters, for example, to adjust the transmit power of the uplink channel, the base station may first issue the power control information of the uplink channel to the user terminal, and the power control information of the uplink channel is used to adjust the transmit power of the uplink channel. The power control instruction information in a predefined format is written in the power control information.

In addition, the power control indication information can be reused with TPC signaling.

Step S20: Adjust the transmit power of the uplink channel through the power control instruction information.

It should be understood that the transmission power adjustment operation is instructed through the parsed power control instruction information.

In a specific implementation, the power control indication information parsed out in the scheduling DCI may be used to indicate the adjustment operation of the transmission power. The power control instruction information is a character string composed of 0 and 1. The indication format of the power control indication information is also relatively diversified. For example, it can be one character, including 0 or 1, or two characters, including 00, 01, 10, and 11. Each string corresponds to a value of transmit power.

A type of scenario to which this embodiment is applicable is as follows. In the scenario where the uplink URLLC and eMBB coexist, the uplink channel is the uplink data channel. Specifically, the uplink data channel refers to the PUSCH, and the power control indication information is used The step of adjusting the transmit power of the uplink channel includes:

The URLLC transmission power of the uplink data channel is adjusted by the power control instruction information to handle the transmission conflict between the URLLC and the eMMB.

In a specific implementation, when URLLC and eMMB transmission conflict, URLLC and eMMB will interfere with each other. If retransmission is performed, the transmission delay of URLLC will increase; if eMMB transmission is stopped to reduce the interference to URLLC, although the interference is eliminated more thoroughly, the complexity of the eMBB terminal needs to be increased; if the URLLC transmission power is increased , Even if eMBB interference exists, it can ensure that the received SINR of URLLC meets the demodulation requirements. The third type of processing method ensures the received SINR by increasing the signal power of the useful signal, and only needs to enhance the URLLC.

Therefore, this embodiment will adopt the third type of processing method. As for the specific instruction method, the URLLC transmission power of the uplink data channel is increased by setting the power control instruction information to ensure that the received SINR of the URLLC meets the demodulation requirements, which is effective Alleviate the transmission conflict.

Another type of scenario to which this embodiment is applicable is as follows. In addition to the uplink data channel, it can also be extended to the uplink control channel. Specifically, the step of adjusting the transmit power of the uplink channel through the power control indication information includes:

As for the applicable scenario of this embodiment, that is, the scenario in which the uplink URLLC and eMBB coexist, refer to the schematic diagram of uplink transmission conflict shown in FIG. 3, which involves frequency (Freq), physical resource block i, j can be denoted as PRBi, j, time slot k can be denoted as slotk, and UE1 and UE2 are user terminals. During uplink transmission, UE1 and UE2 have transmission conflicts at the base station.

The scenario where the uplink URLLC and eMBB coexist can occur in the NR Rel 15 system. Among them, NR Rel 15 is the first version of the standard in 5G.

As far as uplink power control is concerned, through uplink power control, the UE in the cell can not only ensure the quality of the data sent in the uplink, but also minimize the interference to other users in the system and extend the battery life of the UE.

In the NR Rel 15 system, the uplink data between different users in the same cell is orthogonal. Therefore, the uplink power control adopted by the NR Rel 15 system will mainly consider how to make the uplink transmission adapt to different wireless transmissions through power control. Environment, including road loss, shadow fading, etc. NR Rel 15 will adopt a combination of open-loop and closed-loop control. The typical operation mode is:

(1) Set a target receive power, and roughly determine the uplink transmit power based on information such as path loss, scheduling resources, and modulation and coding mode, that is, open-loop power control.

(2) Based on a faster adaptive process, the power adjustment information can be sent to the user terminal in time, so that interference can be controlled and the power setting can be adjusted to adapt to the channel conditions, that is, closed-loop power control.

As for the transmission power of the uplink channel involved in this embodiment, it can be specifically the transmission power of the PUSCH in the NR Rel 15 system. Currently, the calculation formula for the transmission power of the PUSCH is as follows:

Among them, P _{PUSCH, b, f, c} (i, j, q _d , l) is the transmission power of PUSCH, i is the index of one PUSCH transmission, and j is the index of open-loop power control parameters (including the target power P _{O_PUSCH, b ,f,c} (j) and path loss factor α _b,f,c (j)); q _d is the index of the reference signal used for path loss measurement to obtain the path loss value PL _b,f,c ( q _d ) is also an open-loop power control parameter; f _b,f,c (i,l) is a closed-loop power control adjustment factor, where l is a closed-loop power control process.

The user terminal determines the closed-loop power control adjustment factor according to the TPC command field sent by the network side. The TPC command field can be carried by the DCI used to schedule the PUSCH in the UE search space, or it can be used in the common search space. It is carried in the DCI format 2_2 carrying the group TPC command field.

Regarding the closed-loop power control in the NR Rel 15 system, NR Rel 15 will use Group common DCI (e.g. DCI format 2_2) and UE-specific DCI (e.gDCI format 0_0/0_1) to indicate closed loop power adjustment.

First, the indication method of Group common DCI is as follows. Its characteristics are (1) DCI includes power indication information of multiple users; (2) Multiple domain values in DCI are for multiple users. Among them, information such as the user's domain index and target base station is configured through high-level signaling. For specific methods, refer to DCI format 2_2 (physical layer indication) and PDCCH-Config/PUSCH-TPC-Command Config (high-level configuration). For a more complete description of the protocol, please refer to 38.212 v15.4.0 and 38.331 v 15.4.0 in the 5G standard, which will not be repeated here.

Second, the UE-specific DCI method has the characteristic that the power adjustment information for the user is indicated in a user-specific scheduling signaling. Among them, UE specific DCI includes DCI format 0_0 and DCI format 0_1. For DCI format 0_0/DCI format 0_1 and a more complete protocol description, please refer to 38.212 v15.4.0 in the 5G standard, which will not be repeated here.

In summary, through the above discussion of the NR Rel 15 system, which involves uplink power control and closed-loop power control, it can be seen that for PUSCH, there is no implementation of indicating open-loop power parameters through physical layer signaling.

Even in the 3GPP Ran1#98 meeting, the method of modifying the open-loop power parameters to deal with resource conflicts is involved, there is no such kind of implementation that indicates the open-loop power parameters through physical layer signaling.

Therefore, this embodiment provides a type of implementation scheme for indicating open-loop power parameters. Specifically, power control indication information will be set in the power control information of the uplink channel, so that the transmission power of the uplink channel can be effectively adjusted, and the solution is There is no defect of indicating power parameters.

Referring to FIG. 4, FIG. 4 is a schematic flowchart of another exemplary embodiment of an uplink power control method according to the present invention. As shown in Fig. 4, this embodiment is based on the embodiment shown in Fig. 2 described above.

Regarding the instruction manner of instructing transmission power adjustment, the power control instruction information is an instruction corresponding to the open-loop power control parameter and/or the closed-loop power control parameter.

It is understandable that this embodiment will specifically give an indication method for instructing transmission power adjustment, which can be recorded as indication mode 1. This indication mode 1 will involve two types of indication information, and the power control indication information includes parameters Type indication information and first parameter content indication information. The parameter type indication information may be marked as indication A, and the first parameter content indication information may be marked as indication B.

The steps of step S20 include:

Step S201: Adjust the transmit power of the uplink channel according to the parameter type indication information and the first parameter content indication information.

Specifically, indicator A is used to determine whether the current control parameter is an open-loop power control parameter or a closed-loop power control parameter, and indicator B is used to determine the parameter content of an open-loop power control parameter or a closed-loop power control parameter. Refer to Table 1 below. , The transmit power of the uplink channel will be adjusted through Indication A and Indication B. The uplink channel can be an uplink control channel or an uplink data channel.

Table 1-Indication Method 1

11	1010	(P ₀₂,a ₂) (P ₀₂ ,a ₂ )	---
11	1111	(P ₀₃,a ₃) (P ₀₃ ,a ₃ )	---

Among them, indication A can be one character, 1 bit, that is 0 or 1; indication B can be two characters, 2 bits, including 00, 01, 10, and 11; the parameter set of open-loop power control parameters is { (P ₀₀ ,a ₀ ),(P ₀₁ ,a ₁ ),(P ₀₂ ,a ₂ ),(P ₀₃ ,a ₃ )}; the parameter set of closed-loop power control parameters is (step0,step1,step2,step3) . In addition, the parameter set of open-loop power control parameters and the parameter set of closed-loop power control parameters are agreed upon by higher-level configuration or protocol. The parameter set of open-loop power control parameters contains at least one set of open-loop power control parameters, and the parameters of closed-loop power control parameters The parameter set includes at least one set of closed-loop power control parameters.

In specific implementation, gNB (ie 5G base station) can use 3bit to indicate power control in scheduling DCI, where 1bit indicates the type of power control parameter, 0 corresponds to the closed-loop power control method, and 1 corresponds to the open-loop power control method; in addition, 2 bits indicate power control parameters, 00, 01, 10, and 11 respectively correspond to one of the parameter sets of power control parameters.

In addition, you can also refer to the calculation formula for the transmission power of the PUSCH, the closed-loop power control parameter corresponds to f _{b, f, c} (i, l) in the calculation formula, and the first bit in the open-loop power control parameter (for example, P ₀₀ ) corresponds to P _{O_PUSCH, b, f, c} (j), and the second bit (for example, a ₀ ) in the _{open-loop power control parameter corresponds to α b, f, c} (j).

As for step0 to step3, which characterize the closed-loop power control parameters, the corresponding values can be defined in advance. For example, it can be defined according to the protocol standard. If the protocol standard involves 0, 1, -1 and 3, these 4 numbers can be combined with step0 To step3 one-to-one correspondence. For example, step0 corresponds to 0, step1 corresponds to 1, step2 corresponds to -1, and step3 corresponds to 3.

Of course, there is no limit to the values corresponding to step0 to step3. This is only for explanation and can be defined according to protocol standards.

Further, the step of adjusting the transmission power of the uplink channel through the parameter type indication information and the first parameter content indication information includes:

Specifically, if the parameter type indication information is 0, the closed-loop power control parameter will be used instead of the open-loop power control parameter. Therefore, the open-loop power control parameter in Table 1 is marked as "--" to indicate that it is not used. On the premise that the indication A is 0, the closed-loop power control parameter corresponding to the indication B will be selected from the parameter set of the closed-loop power control parameters to adjust the transmit power of the uplink channel.

For example, if the indication A=0 in the power control information sent by the network side device (which can be a base station), the indication B=00, the indication A=0 indicates the closed-loop power control parameter, and the indication B=00 indicates the closed-loop power control parameter (step0) ；

If the indication A=0 in the power control information sent by the network side device, the indication B=0, the indication A=0 indicates the closed-loop power control parameter, and the indication B=0 indicates the closed-loop power control parameter (step 1);

If the indication A=0 in the power control information sent by the network side device, the indication B=10, the indication A=0 indicates the closed-loop power control parameter, and the indication B=10 indicates the closed-loop power control parameter (step 2);

If the indication A=0 in the power control information sent by the network side device, the indication B=11, the indication A=0 indicates the closed loop power control parameter, and the indication B=11 indicates the closed loop power control parameter (step 3).

Specifically, if the parameter type indication information is 1, the open-loop power control parameter will be used instead of the closed-loop power control parameter. Therefore, the closed-loop power control parameter in Table 1 is marked as "--" to indicate that it is not used. Under the premise that the indication A is 1, the open-loop power control parameter corresponding to the indication B will be selected from the parameter set of the open-loop power control parameter to adjust the transmit power of the uplink channel.

For example, if the indication A=1, indication B=00 in the power control information sent by the network-side device (which can be a base station), indication A=1 indicates open loop power control parameters, and indication B=00 indicates open loop power control parameters ( P ₀₀ ,a ₀ );

If the indication A=1 in the power control information sent by the network-side device (which can be the base station), the indication B=0, the indication A=1 indicates the open loop power control parameter, and the indication B=0 indicates the open loop power control parameter (P ₀₁ ,a ₁ );

If the indication A=1, indication B=10 in the power control information sent by the network-side device (which can be a base station), indication A=1 indicates open-loop power control parameters, and indication B=10 indicates open-loop power control parameters (P ₀₂ ,a ₂ );

If the indication A=1, indication B=11 in the power control information sent by the network-side device (which can be a base station), indication A=1 indicates open loop power control parameters, and indication B=11 indicates open loop power control parameters (P ₀₃ ,a ₃ ).

It can be seen that this embodiment will combine the parameter type indication information and the first parameter content indication information to indicate the transmit power of the uplink channel. The former indicates whether to select the closed-loop power control parameter or the open-loop power control parameter, and the latter indicates the specific parameter content of the selected parameter. .

Further, if the parameter type corresponding to the parameter type indication information is an open loop power control parameter type, the transmit power of the uplink channel is adjusted according to the open loop power control parameter corresponding to the first parameter content indication information The steps include:

Acquiring the default value of the first preset closed-loop parameter;

It can be understood that, although the indication mode 1 introduced in this embodiment will indicate one of the open-loop power control parameter or the closed-loop power control parameter when instructing the adjustment operation of the transmission power, however, when calculating the transmission power, this Both types of power control parameters will be involved.

In the specific implementation, in order to face this type of situation, if the high-level configuration or the agreement agrees that different open-loop power control parameter configurations use the default closed-loop parameters, then when the indicator A=1 indicates the open-loop power control parameters, it will be displayed. If the power control information does not involve closed-loop power control parameters, the default value of the closed-loop parameter used by the transmission power can be obtained. The default value of the closed-loop parameter can be recorded as the default value of the first preset closed-loop parameter. The default value of the closed-loop parameter can be 0. Configuration or agreement. Then, the transmit power of the uplink channel will be adjusted according to the default value of the closed-loop parameter and the currently determined open-loop power control parameter.

Obtain the first historical closed-loop cumulative parameter;

In specific implementation, in order to face this type of situation, if high-level configurations or protocols can also agree that different open-loop power control parameter configurations use the same closed-loop cumulative parameter, that is, if you encounter a closed-loop power control parameter, accumulate each encounter For closed-loop power control parameters, the cumulative value is recorded as closed-loop cumulative parameters. Therefore, when the transmission power is adjusted again, if an open-loop power control parameter is encountered, the previously calculated closed-loop cumulative parameter is first obtained and recorded as the first historical closed-loop cumulative parameter.

In addition, in order to face this type of situation, if the high-level configuration or protocol can also agree to use an absolute closed-loop parameter for different open-loop power control parameter configurations, that is, when indicating A indicates the open-loop power control parameter, the closed-loop power used by the transmission power is calculated The control parameter is the absolute closed-loop parameter. The absolute closed-loop parameter can default to 0 or can be configured by higher layers; when the indicator A indicates the closed-loop power control parameter, the closed-loop power control parameter used to calculate the transmission power is the closed-loop power control parameter corresponding to the current indicator.

In this embodiment, the parameter type indication information and the first parameter content indication information are combined to indicate the transmission power of the uplink channel. The parameter type indication information represents the parameter type, and the first parameter content indication information represents the parameter content, which improves the indication efficiency.

Referring to FIG. 5, FIG. 5 is a schematic flowchart of still another exemplary embodiment of an uplink power control method of the present invention. As shown in FIG. 5, this embodiment is based on the embodiment shown in FIG. 2, and the power control instruction information includes open-loop power control instruction information and closed-loop power control instruction information.

It is understandable that this embodiment will give another indication method for indicating transmission power adjustment, which can be recorded as indication mode 2. This indication mode 2 will involve two types of indication information, including open-loop power control indication information and closed-loop power control. Power control indication information. The open-loop power control instruction information can be recorded as instruction C, and the closed-loop power control instruction information can be recorded as instruction D.

The steps of step S20 include:

Step S202: Determine an open-loop power control parameter according to the open-loop power control instruction information.

Specifically, the indication C is used to determine the parameter content of the open-loop power control parameter.

Step S203: Determine a closed-loop power control parameter according to the closed-loop power control instruction information.

Specifically, the indicator D is used to determine the parameter content of the closed-loop power control parameter.

Step S204: Adjust the transmit power of the uplink channel according to the open-loop power control parameter and the closed-loop power control parameter.

It should be understood that, referring to Table 2 below, the transmit power of the uplink channel will be adjusted through indication C and indication D.

Table 2-Indication Mode 2

Among them, indication C can be two characters, 2 bits, including 00, 01, 10, and 11; indication B can be two characters, 2 bits, including 00, 01, 10, and 11; open-loop power control parameters The parameter set is {(P ₀₀ ,a ₀ ),(P ₀₁ ,a ₁ ),(P ₀₂ ,a ₂ ),(P ₀₃ ,a ₃ )}; the parameter set of closed-loop power control parameters is (step0,step1, step2, step3). In addition, the parameter set of open-loop power control parameters and the parameter set of closed-loop power control parameters are agreed upon by higher-level configuration or protocol. The parameter set of open-loop power control parameters contains at least one set of open-loop power control parameters, and the parameters of closed-loop power control parameters The parameter set includes at least one set of closed-loop power control parameters.

Therefore, gNB can use 4 bits to indicate power control in scheduling DCI, among which 2 bits indicate open loop power control parameters, 00, 01, 10, and 11 respectively correspond to one of the parameter sets of open loop power control parameters; the other 2 bits indicate The closed-loop power control parameters, 00, 01, 10, and 11 respectively correspond to one of the parameter sets of the closed-loop power control parameters.

Specifically, if the open-loop power control instruction information is 00, it corresponds to the open-loop power control parameter (P ₀₀ , a ₀ ); if at the same time, the closed-loop power control instruction information is 00, then it corresponds to the closed-loop power control parameter (step0 ).

For example, if the power control information sent by the network side device indicates C=00, indicates D=00, indicates C=00 indicates open-loop power control parameters (P ₀₀ , a ₀ ), indicates D=00 indicates closed-loop power control parameters step0 ；

If the indication of the power control information sent by the network side device is C=01, the indication D=00, the indication C=01 indicates the open-loop power control parameter (P ₀₁ , a ₀ ), and the indication D=00 indicates the closed-loop power control parameter step0;

If the indication of the power control information sent by the network side device is C=10, the indication D=00, the indication C=10 indicates the open-loop power control parameter (P ₀₂ , a ₀ ), and the indication D=10 indicates the closed-loop power control parameter step0;

If the indication of the power control information sent by the network side device is C=11, the indication D=00, the indication C=11 indicates the open-loop power control parameter (P ₀₃ , a ₀ ), and the indication D=00 indicates the closed-loop power control parameter step0;

By analogy, the instruction C indicates the open-loop power control parameter, and the instruction D indicates the closed-loop power control parameter. It can be seen that the instructions in this embodiment will indicate two power control parameters at the same time.

Further, the step of adjusting the transmit power of the uplink channel according to the open-loop power control parameter and the closed-loop power control parameter includes:

Obtain the second historical closed-loop cumulative parameter;

Accumulate the second historical closed-loop accumulation parameter and the closed-loop power control parameter to obtain the first current closed-loop accumulation parameter;

It is understandable that when calculating the transmission power, both types of power control parameters will be involved. The adjustment method for adjusting the transmit power of the uplink channel can be further refined.

The first type of adjustment method is that if the high-level configuration or protocol agrees that different open-loop power control parameters use the same closed-loop accumulation parameter, then in the process of applying this embodiment, the closed-loop power control parameter encountered each time is accumulated, for example, The closed-loop power control parameter determined for the first time is 1, and the closed-loop power control parameter determined for the second time is still 1, then the closed-loop power control parameters determined for the first and second times are accumulated, and the closed-loop cumulative parameter obtained is 2; Therefore, the closed-loop power control parameter determined for the third time is still 1, and the obtained closed-loop cumulative parameter is 3.

Therefore, when adjusting the transmission power again, first obtain the previously calculated closed-loop cumulative parameter, that is, the second historical closed-loop cumulative parameter. If the second historical closed-loop cumulative parameter is 2, the closed-loop power control parameter determined this time is 1. , Then the two are accumulated, and the first current closed-loop accumulation parameter obtained is 3. Then, the transmit power of the uplink channel is adjusted according to the open-loop power control parameter and the closed-loop power control parameter, where the value of the closed-loop power control parameter here is the value of the first current closed-loop cumulative parameter, so in essence, it is Adjust the transmit power of the uplink channel according to the open loop power control parameter and the first current closed loop accumulation parameter.

It can be seen that the characteristic of this type of adjustment method is that different open-loop power control parameters all use the same closed-loop accumulation parameter, and the closed-loop accumulation parameter is continuously accumulated.

In specific implementation, there is also a type of adjustment method for adjusting the transmission power of the uplink channel.

The second type of adjustment method is that if the high-level configuration or protocol agrees that different open-loop power control parameters use different closed-loop accumulation parameters, in the process of applying this embodiment, the parameter accumulation will be performed separately for each indication C. For example, if the first indication C is 00, the determined closed-loop power control parameter is 1; if the second indication C is still 00, the determined closed-loop power control parameter is still 1, and the first and second times are accumulated For the determined closed-loop power control parameter, the obtained closed-loop cumulative parameter is 2; however, if the second indication C is not 00, it cannot be accumulated to the closed-loop cumulative parameter corresponding to 00. If the second indication C is 01, It needs to be accumulated to the closed-loop accumulation parameter corresponding to 01.

It can be seen that each open-loop power control parameter has its own corresponding closed-loop cumulative parameter. For example, if there are 4 types of open-loop power control parameters, there will be 4 corresponding closed-loop cumulative parameters, and 4 corresponding closed-loop The accumulated parameters form the first historical closed-loop accumulated parameter set.

Therefore, when the transmission power is adjusted again, if the open-loop power control instruction information is 01, first select the closed-loop cumulative parameter corresponding to 01 from the first historical closed-loop cumulative parameter set, which can be recorded as the third historical Closed loop accumulation parameters. If the third historical closed-loop accumulation parameter is 2, and the closed-loop power control parameter determined this time is 1, then the two are accumulated, and the second current closed-loop accumulation parameter obtained is 3. Then, the transmit power of the uplink channel is adjusted according to the open-loop power control parameter and the closed-loop power control parameter with a value of 3.

It can be seen that the characteristic of this type of adjustment method is that different open-loop power control parameters use different closed-loop accumulation parameters, which continuously accumulate on their own closed-loop accumulation parameters.

The third type of adjustment method is that if a high-level configuration or protocol can also agree that the closed-loop power control parameter used to calculate the transmission power is the closed-loop power control parameter corresponding to the current indication.

In this embodiment, the open-loop power control indication information and the closed-loop power control indication information are combined to indicate the transmission power of the uplink channel, which improves the indication efficiency. At the same time, a variety of adjustment methods are also listed, which can be diversified for closed-loop accumulation.

Referring to FIG. 6, FIG. 6 is a schematic flowchart of another exemplary embodiment of an uplink power control method according to the present invention. As shown in FIG. 6, this embodiment is based on the embodiment shown in FIG. 2, and the power control indication information includes second parameter content indication information.

It is understandable that this embodiment will give another indication method for indicating the adjustment of the transmission power, which may be recorded as indication mode 3. This indication mode 3 only involves one type of indication information, and the content indication information of the second parameter may be recorded. For instructions E.

The steps of step S20 include:

Step S205: Determine corresponding open-loop power control parameters and closed-loop power control parameters according to the second parameter content indication information.

Specifically, the indicator E is used to determine the parameter content of the open-loop power control parameter and the closed-loop power control parameter at the same time. Refer to Table 3 below, and the indicator E will be used to adjust the transmit power of the uplink channel.

Table 3-Indication Mode 3

指示EInstruction E	功率参数组合Power parameter combination
000000	(P ₀₀,a _0,step0) (P ₀₀ ,a _0, step0)
001001	(P ₀₀,a _0,step1) (P ₀₀ ,a _0, step1)
010010	(P ₀₀,a _0,step2) (P ₀₀ ,a _0, step2)
011011	(P ₀₀,a _0,step3) (P ₀₀ ,a _0, step3)
100100	(P ₀₁,a _1,step0) (P ₀₁ ,a _1, step0)
101101	(P ₀₁,a _1,step1) (P ₀₁ ,a _1, step1)
110110	(P ₀₂,a _2,step0) (P ₀₂ ,a _2, step0)
111111	(P ₀₂,a _2,step1) (P ₀₂ ,a _2, step1)

Among them, the indication E can be a string consisting of three characters, 3 bits, including 000, 001, 010, 011, 100, 101, 110, and 111; the set of power parameter combinations corresponding to the indication E is {(P ₀₀ , a _0, step0),(P ₀₀ ,a _0, step1),(P ₀₀ ,a _0, step2),(P ₀₀ ,a _0, step3),(P ₀₁ ,a _1, step0),(P ₀₁ , a _1, step1),(P ₀₂ ,a _2, step0),(P ₀₂ ,a _2, step1)}, each power parameter combination in the set of power parameter combinations includes both open-loop power control parameters and closed-loop power control parameter. In addition, the set of power parameter combinations is agreed upon by a high-level configuration or agreement.

Step S206: Adjust the transmit power of the uplink channel according to the open-loop power control parameter and the closed-loop power control parameter.

Specifically, if the parameter type indication information E is 000, determine the open-loop power control parameter and the closed-loop power control parameter corresponding to 000, and then adjust the uplink channel according to the open-loop power control parameter and the closed-loop power control parameter corresponding to 000 The transmit power. As for the determination method here, a power parameter combination can be introduced, that is, the corresponding power parameter combination is determined according to the second parameter content indication information, and the corresponding open-loop power control parameter and the closed-loop power control parameter are determined according to the power parameter combination.

It can be seen that gNB can use 3bit indicator power control in scheduling DCI, where 000, 001, 010, 011, 100, 101, 110, and 111 respectively correspond to one of the power parameter combination sets.

For example, if the indication E=000 in the power control information sent by the network side device, the indicated power parameter combination is (P ₀₀ ,a _0, step0), that is, the open-loop power control parameter (P ₀₀ ,a ₀ ), and the closed-loop power Control parameter step0;

If the indication E=001 in the power control information sent by the network side device, the indicated power parameter combination is (P ₀₀ ,a _0, step1), that is, the open-loop power control parameter (P ₀₀ ,a ₀ ), the closed-loop power control parameter step1;

If the indication E in the power control information sent by the network side device is equal to 010, the indicated power parameter combination is (P ₀₀ ,a _0, step2), that is, the open-loop power control parameter (P ₀₀ ,a ₀ ), the closed-loop power control parameter step2;

If the indication E=011 in the power control information sent by the network side device, the indicated power parameter combination is (P ₀₀ ,a _0, step3), that is, the open-loop power control parameter (P ₀₀ ,a ₀ ), the closed-loop power control parameter step3;

If the indication E=100 in the power control information sent by the network-side device, the indicated power parameter combination is (P ₀₁ ,a _1, step0), that is, the open-loop power control parameter (P ₀₁ ,a ₁ ), the closed-loop power control parameter step0;

If the indication E=101 in the power control information sent by the network side device, the indicated power parameter combination is (P ₀₁ ,a _1, step1), that is, the open-loop power control parameter (P ₀₁ ,a ₁ ), the closed-loop power control parameter step1;

If the indication E=110 in the power control information sent by the network side device, the indicated power parameter combination is (P ₀₂ ,a _2, step0), that is, the open-loop power control parameter (P ₀₂ ,a ₂ ), the closed-loop power control parameter step0;

If the indication E=111 in the power control information sent by the network-side device, the indicated power parameter combination is (P ₀₂ , a _{2, step 1} ), that is, the open-loop power control parameter (P ₀₂ , a ₂ ), the closed-loop power control parameter step1.

Obtain the fourth historical closed-loop cumulative parameter;

In addition, in addition to such adjustment methods, if the high-level configuration or protocol agrees that different open-loop power control parameters use the same closed-loop accumulation parameter, then in the process of applying this embodiment, the closed-loop power control parameters encountered each time are accumulated. The principle can be referred to the first type of adjustment mode of the embodiment shown in FIG. 5.

In a specific implementation, the adjustment method for adjusting the transmit power of the uplink channel is specifically, if the high-level configuration or the protocol agrees that different open-loop power control parameters use different closed-loop accumulation parameters, then in the process of applying this embodiment, The parameter accumulation will be performed separately for each instruction E. For example, if the first two digits of the first indication E are 00, the open-loop power control parameter is (P ₀₀ ,a ₀ ), and the determined closed-loop power control parameter is 1; if the first two digits of the second indication E are If it is still 00, the determined closed-loop power control parameter is still 1, and the closed-loop power control parameters determined for the first time and the second time are accumulated, and the closed-loop accumulated parameter obtained is 2; however, if the first two digits of the second indication E are not If it is 00 and not 01, it cannot be accumulated to the closed-loop accumulation parameter corresponding _{to (P 00} , a _{0 ).}

It can be seen that each open-loop power control parameter has its own corresponding closed-loop cumulative parameter. For example, if there are 3 types of open-loop power control parameters, there will be 3 corresponding closed-loop cumulative parameters, and 3 corresponding closed-loop The accumulated parameters form the second historical closed-loop accumulated parameter set. For the subsequent principles, refer to the embodiment shown in FIG. 5 above.

In addition, in addition to such adjustment methods, if high-level configuration or agreement can also agree not to perform closed-loop accumulation operation, that is, the closed-loop power control parameter used to calculate the transmission power is directly the closed-loop power control parameter corresponding to the current indication.

It should be understood that since different closed-loop parameter sets are used for the open-loop power parameters in this embodiment, the signaling overhead can be reduced as much as possible.

In this embodiment, two types of control parameters are determined at the same time through one type of indication, that is, the second parameter content indication information, so as to indicate the transmission power of the uplink channel, which greatly improves the indication efficiency.
