Technical Field

The present application relates to the field of communications, and in particular, to a power control method and apparatus.

Background

In the prior art, a terminal device may operate with a transmit power of a power level 2(26 decibel milliwatts (dBm)), and may increase a coverage area and a transmission performance of an uplink channel of a mobile communication network by increasing the transmit power of the terminal device compared with an operation with a transmit power of a default power level 3(23dBm), thereby improving user experience of a cell edge user.

When the terminal device operates with a transmit power of power class 2(26dBm), if the electromagnetic wave absorption ratio of the terminal device exceeds a specified limit value, the terminal device needs to directly return the transmit power to default power class 3(23dBm) to meet the requirement of the electromagnetic wave absorption ratio of the human body, thereby avoiding the harm of higher transmit power to the human body.

However, the current scheme of directly backing off the uplink transmit power of the terminal device to the default power level of 3(23dBm) in the TDD single carrier mode of 5G SA or 5G NSA mode is too conservative. In 5G SA carrier aggregation mode, the third generation partnership project (3 GPP) specifications have supported high transmit power levels (power level 2(26dBm)) for partial carrier aggregation. In this scenario, how to control the uplink transmission power of the terminal device to meet the requirement of the human body electromagnetic wave absorption ratio is a problem to be solved urgently at present.

Disclosure of Invention

The application provides a power control method and a power control device, which can make the coverage area of an uplink channel of terminal equipment as large as possible and make the transmission performance as good as possible when backing off power.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, a power control method is provided, which may be executed by a network device or a terminal device, or may be executed by a component of the network device or the terminal device, such as a processor, a chip, or a chip system of the network device or the terminal device, or may be implemented by a logic module or software that can implement all or part of the functions of the network device or the terminal device, and this application takes the network device or the terminal device as an example to execute the method. The method comprises the following steps: the network equipment or the terminal equipment determines whether the maximum transmitting power of the terminal equipment is larger than a first power, and when the maximum transmitting power of the terminal equipment is larger than the first power and the uplink transmitting power of the auxiliary carrier existing in the plurality of carriers is larger than a second power, the network equipment or the terminal equipment down-regulates the uplink transmitting power of the corresponding carrier according to the sequence of the main carrier after the auxiliary carrier is carried first until the maximum transmitting power of the terminal equipment is not larger than the first power. The maximum transmission power of the terminal device is determined according to the uplink transmission power supported by each carrier in a plurality of carriers supported by the terminal device and the duty ratio value allocated to each carrier by the network device, wherein the plurality of carriers include a primary carrier and one or more secondary carriers.

According to this scheme, since the RRC connection message is transmitted only on the primary carrier and the PUCCH control information is also transmitted only on the uplink primary carrier, it is necessary to preferentially secure the uplink transmission power of the primary carrier. In the power control method provided in the embodiment of the present application, when the maximum transmit power of the terminal device is greater than the first power and the uplink transmit power of the secondary carrier existing in the multiple carriers is greater than the second power, the network device or the terminal device preferentially reduces the uplink transmit power of the secondary carrier and then reduces the uplink transmit power of the primary carrier, so that the uplink transmit power of the primary carrier is ensured to be as large as possible, the coverage area of the uplink channel of the terminal device is as large as possible, the transmission performance is as good as possible, and further, the adverse effect of the transmit power backoff on the user experience of the cell edge user is reduced as much as possible. In addition, in the embodiment of the present application, the network device or the terminal device compares the uplink transmission power of the auxiliary carrier with the second power (that is, the minimum uplink transmission power required by a single carrier), and only adjusts the uplink transmission power of the auxiliary carrier whose uplink transmission power is greater than the second power, so that it is possible to avoid adjusting the uplink transmission power of the auxiliary carrier to be lower than the second power, thereby ensuring that the coverage area of the uplink channel of the terminal device is as large as possible, and the transmission performance is as good as possible, so as to reduce adverse effects caused by transmission power backoff on user experience of cell edge users as possible.

The power control method provided by the embodiment of the present application may be executed by the network device 20, or may also be executed by the terminal device 30, and the power control method provided by the embodiment of the present application will be separately described below with reference to the accompanying drawings, taking the network device 20 shown in fig. 2 as an execution subject, or taking the terminal device 30 as an execution subject.

It is to be understood that, in the embodiments of the present application, the executing subject may perform some or all of the steps in the embodiments of the present application, and these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations. Further, the various steps may be performed in a different order presented in the embodiments of the application, and not all operations in the embodiments of the application may be performed.

It is understood that, in various embodiments of the present application, the interaction mechanism between the network device and the terminal device may be modified appropriately to adapt to the interaction between the CU or the DU and the terminal device.

It should be noted that, in the following embodiments of the present application, names of messages between devices or names of parameters in messages are only an example, and other names may also be used in a specific implementation, which is not specifically limited in this embodiment of the present application.

Taking the network device 20 as an execution subject, as shown in fig. 3, the power control method provided in the embodiment of the present application includes the following steps:

s301, the network device determines whether the maximum transmitting power of the terminal device is larger than the first power.

The maximum transmission power of the terminal device is determined according to the uplink transmission power supported by each carrier in the multiple carriers supported by the terminal device and the duty ratio value allocated to each carrier by the network device. The plurality of carriers supported by the terminal device includes a primary carrier and one or more secondary carriers.

As a possible implementation, the maximum transmission power of the terminal device in step S301 satisfies the following formula (1):

where, Dutyi is the duty cycle value of a certain carrier,is thatA value of the transmit power supported by the carrier.

For example, the terminal device 1 supports an uplink carrier aggregation function (CA _ n1A-n41A-n78A) of an n1(2.1GHz) + n41(2.6GHz) + n78(3.5GHz) frequency band, where the n41 frequency band is a main carrier. The n1 frequency band supports 23dBm uplink transmission power, the n41 frequency band and the n78 frequency band support 26dBm uplink transmission power, and the network device allocates 50%, 20% and 40% duty cycle values to carriers of the n1 frequency band, the n41 frequency band and the n78 frequency band respectively. Based on the above, the maximum transmission power of the terminal device 1 is 50%. multidot.23 dBm + 20%. multidot.26 dBm + 40%. multidot.26 dBm, 25.3 dBm.

It can be understood that, in the embodiment of the present application, the uplink transmission power supported by the carrier may be replaced by the maximum uplink transmission power supported by the carrier, and the uplink transmission power and the maximum uplink transmission power may be replaced by each other in the present application, which is described in a unified manner herein and will not be described again below.

As a possible implementation, the first power may be a limit value of a Specific Absorption Rate (SAR), for example, the first power may be 23dBm, or the first power may be 200mW since 23dBm may be converted to 200 milliwatts (mW).

It should be noted that, because the SAR limit is not necessarily satisfied every moment, as long as the average transmission power within each radio frame length is less than or equal to the SAR limit, it can be regarded that the maximum transmission power of the terminal device is less than or equal to the SAR limit, and therefore, when the maximum transmission power of the terminal device is less than or equal to the SAR limitThe SAR limit requirements are met.

S302, when the maximum transmitting power of the terminal equipment is larger than the first power and the uplink transmitting power of the auxiliary carrier exists in the plurality of carriers and is larger than the second power, the network equipment reduces the uplink transmitting power of the corresponding carrier according to the sequence of the main carrier after the auxiliary carrier is carried out first until the maximum transmitting power of the terminal equipment is not larger than the first power.

As a possible implementation, the second power is used to indicate the lowest uplink transmit power required for a single carrier.

As a possible implementation, the second power may be determined according to the first power and the number of the plurality of carriers supported by the terminal device.

Illustratively, the second power satisfies the following equation (2):

Power_thres.2mmmW ÷ n, formula (2)

Wherein, Power_thres.For the second power, 200mW is the first power, i.e. the limit of SAR, and n is the number of the plurality of carriers supported by the terminal device. The above equation (2) can ensure that the sum of the threshold power of each component carrier is not greater than 23dBm, and ensure that the SAR limit is not exceeded.

For example, taking the terminal device 1 in the above step S301 as an example, if the terminal device 1 supports 3 carriers of the n1 band, the n41 band and the n78 band, that is, if n is 3, the second Power is Power_thres.＝200mW/3＝66.7mW＝18.2dBm。

Since the RRC connection message is transmitted only on the primary carrier and the PUCCH control information is also transmitted only on the uplink primary carrier, it is necessary to preferentially secure uplink transmission power of the primary carrier. In the power control method provided in the embodiment of the present application, when the maximum transmission power of the terminal device is greater than the first power and the uplink transmission power of the secondary carrier existing in the multiple carriers is greater than the second power, the network device preferentially down-regulates the uplink transmission power of the secondary carrier and then down-regulates the uplink transmission power of the main carrier, so that it is ensured that the uplink transmission power of the main carrier is as large as possible. In addition, in the embodiment of the present application, the network device compares the uplink transmission power of the auxiliary carrier with the second power (that is, the minimum uplink transmission power required by a single carrier), and only adjusts the uplink transmission power of the auxiliary carrier whose uplink transmission power is greater than the second power, so that it is possible to avoid adjusting the uplink transmission power of the auxiliary carrier to be lower than the second power, thereby ensuring that the coverage area of the uplink channel of the terminal device is as large as possible, and the transmission performance is as good as possible, thereby reducing adverse effects caused by transmission power backoff on user experience of cell edge users as possible.

Optionally, before step S301, the power control method provided in this embodiment of the present application may further include: the network device receives a first message from the terminal device, where the first message includes uplink transmit power supported by each carrier of the terminal device.

Optionally, after step S302, the power control method provided in the embodiment of the present application may further include: and the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

It should be noted that, in this embodiment of the present application, the network device may send the adjusted uplink transmission power of the carrier and the duty ratio value allocated by the network device to the terminal device at the same time; or the duty ratio value allocated to each carrier by the network equipment is sent to the terminal equipment, and then the adjusted uplink transmitting power of the carrier is sent to the terminal equipment; or, the adjusted uplink transmission power of the carrier may be sent to the terminal device, and then the duty ratio value allocated to each carrier by the network device is sent to the terminal device, which is described in this specification in a unified manner.

In the above scheme, when the maximum transmission power of the terminal device is greater than the first power and the uplink transmission power of the secondary carrier existing in the multiple carriers is greater than the second power, the network device reduces the uplink transmission power of the corresponding carrier according to the sequence of the primary carrier after the secondary carrier. Optionally, as shown in fig. 3, the power control method provided in the embodiment of the present application further includes the following steps:

and S303, under the condition that the maximum transmitting power of the terminal equipment is greater than the first power and the uplink transmitting power of the auxiliary carrier does not exist in the plurality of carriers and is greater than the second power, the network equipment adjusts the current uplink transmitting power of the main carrier.

The specific implementation of the network device adjusting the current uplink transmission power of the main carrier will be described later, and will not be described herein.

Optionally, the power control method provided in the embodiment of the present application further includes: and under the condition that the maximum transmitting power of the terminal equipment is not greater than the first power, the terminal equipment transmits uplink information according to the current uplink transmitting power of each carrier.

The above is a general description of the power control method provided in the present application, and the power control method provided in the present application will be described below with reference to fig. 4 to 6.

Referring to fig. 4, when a plurality of carriers supported by the terminal device includes an auxiliary carrier, the specific implementation of step S302 includes the following steps:

and S11, when the maximum transmitting power of the terminal equipment is greater than the first power and the uplink transmitting power of the auxiliary carrier exists in the plurality of carriers and is greater than the second power, the network equipment reduces the current uplink transmitting power of the auxiliary carrier by a first set step length to obtain a first uplink transmitting power.

As a possible implementation, the first setting step is a preset δ dB, for example, δ dB may be 3dB, or may be 4dB, which is not limited in this application.

And S12, if the first uplink transmission power is not less than the second power, the network device determines the current maximum transmission power of the terminal device according to the first uplink transmission power, the uplink transmission power supported by the main carrier and the duty ratio value allocated to each carrier by the network device.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S12 isTherein, Duty_iIs the duty cycle value of a certain carrier, if the uplink transmission power of the carrier is adjusted,when the adjusted current uplink transmission power, for example, the first uplink transmission power, of the carrier is not adjusted,the value of the supported transmit power for that carrier.

And S13, if the first uplink transmitting power is smaller than the second power, the network equipment adjusts the current uplink transmitting power of the auxiliary carrier to the second power, and determines the current maximum transmitting power of the terminal equipment according to the second power, the uplink transmitting power supported by the main carrier and the duty ratio value distributed by the network equipment for each carrier.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S13 isTherein, Duty_iIs the duty ratio value of a certain carrier, when the uplink transmission power of the carrier is adjusted to the second power,is the second power, when the uplink transmit power of the carrier is not adjusted,the value of the uplink transmit power supported for that carrier.

S14, under the condition that the current maximum transmitting power of the terminal equipment is larger than the first power, if the uplink transmitting power of the auxiliary carrier is larger than the second power, the network equipment repeatedly executes the steps S11-S13; if the uplink transmitting power of the auxiliary carrier is not larger than the second power, the network equipment adjusts the current uplink transmitting power of the main carrier until the maximum transmitting power of the terminal equipment is not larger than the first power.

That is to say, after the uplink transmission power of the secondary carrier is adjusted, if the current maximum transmission power of the terminal device is still greater than the first power and the adjusted uplink transmission power of the secondary carrier is still greater than the second power, the uplink transmission power of the secondary carrier is again decreased by the first set step length, and the network device repeatedly executes steps S11-S13 until the maximum transmission power of the terminal device is not greater than the first power. Or, after the uplink transmission power of the auxiliary carrier is adjusted, if the current maximum transmission power of the terminal device is still greater than the first power and the adjusted uplink transmission power of the auxiliary carrier is not greater than the second power, the network device does not adjust the uplink transmission power of the auxiliary carrier any more, and adjusts the uplink transmission power of the main carrier until the maximum transmission power of the terminal device is not greater than the first power.

Based on the scheme, under the condition that the maximum transmitting power of the terminal equipment is not larger than the first power, the network equipment adjusts the power by reducing the uplink transmitting power of the auxiliary carrier by a first set step length every time, the uplink transmitting power of the auxiliary carrier can be made as large as possible, the coverage area of an uplink channel of the terminal equipment is ensured to be as large as possible, and the transmission performance is ensured to be as good as possible.

As a possible implementation, after step S14, the power control method provided in the embodiment of the present application may further include: and the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

Optionally, in this embodiment of the application, after step S12 or step S13, the power control method provided in this embodiment of the application may further include: if the current maximum transmitting power of the terminal equipment is not larger than the first power, the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment, so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

The foregoing scheme is directed to the description of the specific implementation of step S302 when one secondary carrier is included in multiple carriers supported by the terminal device, and the specific implementation of step S302 is described below with reference to fig. 5 when multiple secondary carriers are included in multiple carriers supported by the terminal device.

Referring to fig. 5, for the case that the plurality of carriers supported by the terminal device includes a plurality of secondary carriers, the specific implementation of step S302 includes the following steps:

and S21, when the maximum transmitting power of the terminal equipment is greater than the first power and the uplink transmitting power of the auxiliary carrier exists in the plurality of carriers and is greater than the second power, the network equipment reduces the current uplink transmitting power of the first auxiliary carrier in the plurality of auxiliary carriers by a first set step length to obtain a second uplink transmitting power.

The first auxiliary carrier is an auxiliary carrier with the highest carrier priority in the carriers of which the current uplink transmitting power of the auxiliary carrier is greater than the second power.

As a possible implementation, in the embodiment of the present application, the highest priority refers to the lowest channel quality of the uplink carrier, that is, the priority of the secondary carrier with the lowest channel quality of the uplink carrier is the highest.

As a possible implementation, the uplink carrier channel quality may be determined by the network device based on a Reference Signal Receiving Power (RSRP) and/or by the network device based on a Channel Quality Indicator (CQI), or may be determined by the network device through other manners, which is not limited in this application.

For example, in the terminal device 1 in step S301, when the maximum transmit power 23.5dBm of the terminal device 1 is greater than the first power 23dBm, the uplink transmit power 26dBm of the secondary carrier n78 frequency band carrier is greater than the second power 18.2dBm, and the uplink transmit power 23dBm of the secondary carrier n1 frequency band carrier is greater than the second power 18.2dBm, if the network device determines that the uplink carrier channel quality of the n78 frequency band carrier supported by the terminal device is the worst, the network device decreases the current uplink transmit power 26dBm of the n78 frequency band carrier by a first set step, for example, the network device decreases the current uplink transmit power 26dBm of the n78 frequency band carrier by 3dBm, and obtains the second uplink transmit power 3535 78 dBm, which is 23 dBm-3 dBm.

It is to be understood that the second uplink transmission power may be the same as the first uplink transmission power in step S11, or may be different from the first uplink transmission power. For example, when the initial uplink transmission power of the first secondary carrier is the same as the initial uplink transmission power of the secondary carrier in the above step S11, the second uplink transmission power may be the same as the first uplink transmission power in the above step S11. When the initial uplink transmission power of the first secondary carrier is different from the initial uplink transmission power of the secondary carrier in the step S11, the second uplink transmission power may be different from the first uplink power in the step S11.

And S22, if the second uplink transmission power is not less than the second power, the network device determines the current maximum transmission power of the terminal device according to the second uplink transmission power, the uplink transmission power supported by the carriers except the first auxiliary carrier in the plurality of auxiliary carriers, and the duty ratio value allocated to each carrier by the network device.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S22 isTherein, Duty_iIs the duty cycle value of a certain carrier, if the uplink transmission power of the carrier is adjusted,when the carrier is the first auxiliary carrier,and is the second uplink transmission power. When the uplink transmit power of the carrier is not adjusted,the value of the uplink transmit power supported for that carrier.

Exemplarily, taking the terminal device 1 in the above step S21 as an example, the current maximum transmit power of the terminal device is 50% × 23dBm + 20% × 26dBm + 40% × 23dBm is 24.1 dBm.

And S23, if the second uplink transmission power is smaller than the second power, the network device adjusts the current uplink transmission power of the first auxiliary carrier to the second power, and determines the current maximum transmission power of the terminal device according to the second power, the uplink transmission power supported by the carriers except the first auxiliary carrier in the plurality of auxiliary carriers, and the duty ratio value allocated to each carrier by the network device.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S23 isTherein, Duty_iIs the duty cycle value of a certain carrier, if the uplink transmission power of the carrier is adjusted,when the carrier is the first auxiliary carrier,is the second power. When the uplink transmit power of the carrier is not adjusted,the value of the supported transmit power for that carrier.

For example, taking the terminal device 1 in the step S21 as an example, if the current uplink transmit power of the n78 band carrier supported by the terminal device 1 is down-regulated three times, and the obtained second transmit power is 26dBm-3 dBm-17 dBm < 18.2dBm, the network device adjusts the current uplink transmit power of the n78 band carrier by 17dBm to 18.2 dBm. At this time, the current maximum transmit power of the terminal device is 50%. 23dBm + 20%. 26dBm + 40%. 18.2dBm is 23.1 dBm.

S24, under the condition that the current maximum transmitting power of the terminal equipment is larger than the first power, if the uplink transmitting power of the first auxiliary carrier is larger than the second power, the network equipment repeatedly executes the steps S21-S23; if the uplink transmission power of the first auxiliary carrier is not greater than the second power and the uplink transmission power of the auxiliary carrier existing in the plurality of carriers is greater than the second power, the network device repeatedly executes the steps S21-S23 until the current uplink transmission power of the auxiliary carrier not existing in the plurality of carriers is greater than the second power, and then the network device adjusts the current uplink transmission power of the main carrier until the maximum transmission power of the terminal device is not greater than the first power.

That is to say, after the uplink transmission power of the first auxiliary carrier is adjusted, if the current maximum transmission power of the terminal device is still greater than the first power and the adjusted uplink transmission power of the first auxiliary carrier is still greater than the second power, the network device decreases the uplink transmission power of the first auxiliary carrier by the first set step length again, and S21-S23 is repeatedly executed until the maximum transmission power of the terminal device is not greater than the first power. Or after the uplink transmission power of the first auxiliary carrier is adjusted, if the current maximum transmission power of the terminal device is still greater than the first power and the adjusted uplink transmission power of the first auxiliary carrier is not greater than the second power, the network device continues to down-regulate the uplink transmission power of the auxiliary carrier with the highest priority among the other auxiliary carriers in the plurality of carriers, where the uplink transmission power of the auxiliary carrier is greater than the second power, and repeatedly executes S21-S23 until the maximum transmission power of the terminal device is not greater than the first power. If the uplink transmitting power of all the auxiliary carriers in the plurality of carriers is not greater than the second power, the network equipment does not adjust the uplink transmitting power of the auxiliary carriers any more, and adjusts the uplink transmitting power of the main carrier until the maximum transmitting power of the terminal equipment is not greater than the first power.

Exemplarily, taking the terminal device 1 in the step S22 as an example, if the current maximum transmit power 24.1dBm of the terminal device is greater than the first power 23dBm, and the current uplink transmit power 23dBm of the n78 frequency band carrier is greater than the second power 18.2dBm, the network device decreases the current uplink transmit power 23dBm of the n78 frequency band carrier by a first set step, for example, the network device decreases the current uplink transmit power 23dBm of the n78 frequency band carrier by 3dBm, so as to obtain the second uplink transmit power

And repeating S21-S23 until the maximum transmitting power of the terminal equipment is not more than the first power when the maximum transmitting power is 26dBm-3 dBm-20 dBm. Or, taking the terminal device 1 in the step S23 as an example, the current maximum transmit power 23.1dBm of the terminal device is still greater than the first power 23dBm, and the current uplink transmit power 18.2dBm of the n78 frequency band carrier is not greater than the second power 18.2dBm, the network device continues to down-regulate the uplink transmit power of the n1 frequency band carrier, and repeatedly executes S21-S23 until the maximum transmit power of the terminal device is not greater than the first power. If the uplink transmitting power of the n1 frequency band carrier and the n78 frequency band carrier are not greater than the second power, the network device does not adjust the uplink transmitting power of the auxiliary carrier any more, and adjusts the uplink transmitting power of the main carrier n41 frequency band carrier until the maximum transmitting power of the terminal device is not greater than the first power.

Based on the scheme, under the condition that the maximum transmitting power of the terminal equipment is not larger than the first power, the network equipment adjusts the power by reducing the transmitting power of the auxiliary carrier with high priority by a first set step length each time, so that the transmitting power of the auxiliary carrier with low priority is as large as possible, the coverage and the transmission performance of an uplink channel of the terminal equipment are ensured to be as good as possible, meanwhile, when the uplink transmitting power of the auxiliary carrier is lower than the second power as large as possible, the network equipment adjusts the uplink transmitting power of the auxiliary carrier to the second power, the transmitting power of the auxiliary carrier is ensured not to be reduced to be lower than the required minimum transmitting power, and the problem that the coverage and the transmission performance of the uplink channel of the terminal equipment are influenced due to the fact that the transmitting power of the auxiliary carrier is too low, and further the user experience is influenced can be avoided.

As a possible implementation, after step S24, the power control method provided in the embodiment of the present application further includes: and the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

Optionally, in this embodiment of the application, after step S22 or step S23, the power control method provided in this embodiment of the application may further include: if the current maximum transmitting power of the terminal equipment is not larger than the first power, the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment, so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

In the above solution, for the specific implementation of step S302 in the case that the maximum transmission power of the terminal device is greater than the first power and the uplink transmission power of the secondary carrier in the multiple carriers is greater than the second power, the specific implementation of the network device for adjusting the current uplink transmission power of the primary carrier is provided below with reference to fig. 6, and includes the following steps:

and S31, the network equipment reduces the current uplink transmitting power of the main carrier by a second set step length to obtain a third uplink transmitting power.

As a possible implementation, the second setting step is a predetermined α dB, for example, α dB may be 3dB, or may be 4dB, which is not limited in this application.

The first setting step in step S11 and step S21 may be the same as or different from the second setting step in step S31, and the present application does not limit this.

And S32, if the third uplink transmission power is not less than the second power, the network device determines the current maximum transmission power of the terminal device according to the third uplink transmission power, the uplink transmission power supported by the auxiliary carrier and the duty ratio value allocated to each carrier by the network device.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S32 isTherein, Duty_iIs the duty cycle value of a certain carrier, if the uplink transmission power of the carrier is adjusted,the adjusted current uplink transmission power, for example, the third uplink transmission power, for the carrier. When the uplink transmit power of the carrier is not adjusted,the value of the supported transmit power for that carrier.

And S33, if the third uplink transmitting power is smaller than the second power, the network device adjusts the current uplink transmitting power of the main carrier to the second power, and determines the current maximum transmitting power of the terminal device according to the second power, the uplink transmitting power supported by the auxiliary carrier and the duty ratio value allocated to each carrier by the network device.

As a possible implementation, referring to the above equation (1), the current maximum transmission power of the terminal device in step S33 isTherein, Duty_iIs the duty ratio value of a certain carrier, when the uplink transmitting power of the carrier is adjustedWhen the total power is the second power, the power is reduced,is the second power. When the uplink transmit power of the carrier is not adjusted,the value of the uplink transmit power supported for that carrier.

S34, if the uplink transmit power of the primary carrier is greater than the second power under the condition that the current maximum transmit power of the terminal device is greater than the first power, the network device repeatedly executes steps S31-S33 until the maximum transmit power of the terminal device is not greater than the first power.

That is to say, after the uplink transmission power of the primary carrier is adjusted, if the current maximum transmission power of the terminal device is still greater than the first power and the adjusted uplink transmission power of the primary carrier is still greater than the second power, the network device decreases the uplink transmission power of the primary carrier by the second set step length again, and the steps S31-S33 are repeatedly executed until the maximum transmission power of the terminal device is not greater than the first power.

Based on the scheme, under the condition that the maximum transmitting power of the terminal equipment is not larger than the first power and the uplink transmitting power of the auxiliary carrier which does not exist in the plurality of carriers is larger than the second power, the network equipment adjusts the power by reducing the transmitting power of the main carrier by a second set step length each time, so that the transmitting power of the main carrier is as large as possible, and the coverage range of an uplink channel of the terminal equipment is as large as possible and the transmission performance is as good as possible. Meanwhile, when the transmitting power of the main carrier is lower than the second power, the network device adjusts the transmitting of the main carrier to the second power, so that the transmitting power of the main carrier is ensured not to be reduced to be lower than the required minimum transmitting power, and the problem that the coverage and transmission performance of an uplink channel of the terminal device are influenced due to the fact that the transmitting power of the main carrier is too low, and further user experience is influenced can be avoided.

Optionally, as shown in fig. 6, the power control method provided by the present application may further include:

s35, when the current maximum transmission power of the terminal device is greater than the first power, if the uplink transmission power of the primary carrier is not greater than the second power, the network device instructs the terminal to transmit uplink information according to a preset 3GPP protocol.

Illustratively, the network device instructs the terminal device to transmit uplink information at a default maximum transmit power of 23 dBm.

As a possible implementation, after step S34, the power control method provided in the embodiment of the present application further includes: and the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

Optionally, in this embodiment of the application, after step S32 or step S33, the power control method provided in this embodiment of the application may further include: if the current maximum transmitting power of the terminal equipment is not larger than the first power, the network equipment sends the adjusted uplink transmitting power of the carriers and the duty ratio value allocated to each carrier by the network equipment to the terminal equipment, so that the terminal equipment transmits uplink information according to the current uplink transmitting power of the plurality of supported carriers and the duty ratio value allocated to each carrier by the network equipment. Optionally, the network device may further send uplink transmit power supported by the unadjusted carrier to the terminal device, which is not specifically limited in this embodiment of the present application.

As a possible implementation, the power control method provided in the foregoing embodiment uses a network device as an execution subject, and the power control method provided in the embodiment of the present application may also use a terminal device as an execution subject. The specific implementation of the terminal device executing the power control method is similar to the specific implementation of the network device executing the power control method, and the differences include: first, when the power control method provided in the embodiment of the present application is executed by a terminal device, before step S301, the power control method provided in the present application may further include: the terminal equipment sends the maximum uplink transmission power supported by each carrier to the network equipment and receives the duty ratio value distributed to each carrier by the network equipment from the network equipment. Secondly, when the power control method provided in this embodiment of the present application is executed by a terminal device, since the terminal device can obtain the uplink transmission power of the adjusted carrier, it is not necessary for the network device to send the uplink transmission power of the adjusted carrier to the terminal device, and the terminal device can directly transmit uplink information according to the current uplink transmission power of the multiple supported carriers and the duty ratio value allocated to each carrier by the network device. Then, when the power control method provided in this embodiment is executed by the terminal device, if the uplink transmit power of the primary carrier is not greater than the second power under the condition that the current maximum transmit power of the terminal device is greater than the first power, the terminal device performs uplink information transmission according to a preset 3GPP protocol. Illustratively, the terminal equipment performs uplink information transmission according to a default maximum transmission power of 23 dBm.
