Description

Power control method, device and computer-readable storage medium

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on August 10, 2018 with application number 201810911105.0, the entire contents of which are incorporated herein by reference.

Technical field

The present disclosure relates to the technical field of wireless communications, and in particular, to a power control method, a power control device, and a computer-readable storage medium.

Background technique

With the rapid development of wireless communication technology, a new generation of wireless communication (New Radio, NR for short) technology came into being. At present, NR technology has entered the development stage, and as the fifth generation mobile communication system, the NR system needs to support a variety of different application scenarios, and also needs to support traditional frequency bands, new high frequency bands, and beam modes at the same time.

In the dual connectivity (DC) scenario of the NR system, the terminal communicates with the base station through two connections. These two connections can support carrier aggregation, that is, each connection includes multiple member cells (CC), and each connected multiple cell is called a cell group (Cell Croup, CG for short).

In the NR DC system, the uplink transmission power is related to many factors, such as path loss, target received power, maximum transmit power, closed-loop power adjustment, transmission bandwidth, and transmission rate. In addition, it is difficult to completely align multiple uplink transmissions in two CGs in the NR DC system. When allocating power to each uplink transmission, it is difficult to predict whether there will be transmission in the future, so the power sharing of multiple uplink transmissions will be complicated.

In the related art, there is no power control scheme for uplink transmission in the NR DC system.

detailed description

Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.

An embodiment of the present disclosure provides a power control method, which is applicable to a transmission power allocation process for uplink transmission in an NR DC system and is performed on a terminal. As shown in FIG. 1, the power control method includes the following steps.

S101. Obtain a power control parameter, where the power control parameter includes a required power for uplink transmission in a first cell group CG and a required power for uplink transmission in a second CG, and a high power ratio of the first CG and a low power of the first CG. At least one of a power ratio, a high power ratio of the second CG, and a low power ratio of the second CG.

Among them, any one of the first CG and the second CG may be a primary cell group (MCG), and the other is a secondary cell group (SCG). And it should be noted that the Cell can also be replaced by a carrier here.

In one embodiment, the high power ratio and low power ratio of the first CG and the second CG may be configured by the base station and sent to a terminal (User Equipment, UE). Specifically, the RRC (Radio Resource Control) Radio resource control) signaling is configured to the terminal. In another embodiment, the required power for uplink transmission in the first cell group CG and the required power for uplink transmission in the second CG is that the base station sends the uplink transmission information (such as scheduling information or static signaling information) to the terminal. The terminal determines the required power for uplink transmission in the first CG and the second CG according to the uplink transmission information.

Optionally, the sum of the high power ratio of the first CG and the high power ratio of the second CG is less than or equal to one.

In one embodiment, a high power ratio of the first CG is greater than or equal to a low power ratio of the first CG. In another embodiment, the high power ratio of the second CG is greater than or equal to the low power ratio of the second CG.

For example, the high power of the first CG is 60%, the high power of the second CG is 40%, the low power of the second CG is 30%, and the low power of the second CG is 25%.

In one embodiment, the low power ratio may also be configured as zero. For example, a scenario that meets the following conditions:

1) The first CG and the second CG are synchronized, that is, the first CG and the second CG satisfy a predetermined synchronization requirement;

2) The scheduling intervals of the first CG and the second CG are the same. For example, there are 4 subframes between the UL grant (Uplink grant) information and the PUSCH (Physical Uplink Shared Channel). ;

3) The first CG and the second CG do not support bursty services, such as URLLC (Ultra Reliable & Low Latency Communication, Ultra High Reliability and Low Latency Communication);

4) The symbol / slot length of the CC in the first CG and the second CG is the same.

S102. Determine the transmit power of uplink transmission in the first CG according to the power control parameter.

In this embodiment, the high power ratio is mainly used for determining the transmission power that each CG can occupy when the sum of the required powers of the two CGs is greater than the maximum transmission power. The low power ratio is mainly used to determine the sub-sending power for the target uplink transmission in one of the CGs, and it is impossible to determine whether there is uplink transmission for another CG during the transmission period of the target uplink transmission. Transmission reserves a certain amount of transmit power.

The uplink transmission refers to occupying specific channel resources to send corresponding information. For example, a data packet transmission needs to occupy 4 OFDM (Orthogonal Frequency Division Multiplexing) symbols of the PUSCH. These 4 symbols The PUSCH is called a PUSCH transmission. Similarly, there are PUCCH (Physical Uplink Control Channel) transmission, SRS (Sounding Reference Signal) transmission, PRACH (Physical Random Access Channel) transmission, and Long PUCCH transmission, short PUCCH transmission, long PUSCH transmission, short PUSCH transmission, different types of SRS transmission, etc.

According to the power control method provided by the above disclosed embodiments, the required power for uplink transmission in the first cell group CG, the high power ratio of the first CG, the low power ratio of the first CG, and the required power of uplink transmission in the second CG are provided. At least one power parameter among the high power ratio of the second CG and the low power ratio of the second CG determines the transmit power of uplink transmission in the first CG. The embodiment of the present disclosure proposes a power control scheme for uplink transmission in the NR DC system, and achieves positive technical effects.

It is worth noting that in the embodiments of the present disclosure, except for special instructions, the symbols refer to OFDM symbols.

Further, in combination with the foregoing method flow, the embodiment of the present disclosure, for the realization of step S102, is based on two parameters of high power ratio and low power ratio, respectively, and also provides the following four methods for determining the transmission of uplink transmission in the first CG: How power is achieved.

In a first implementation manner, when the power control parameter includes a low power ratio of uplink transmission in the second CG, as shown in FIG. 2, step S102 includes:

S1021. In the case where it is not possible to determine whether there is uplink transmission in the second CG during the transmission of the target uplink transmission in the first CG, determine that the ratio of the transmission power of the uplink transmission in the first CG to the maximum transmission power is: 1- The low power ratio of the second CG.

A second implementation manner, as shown in FIG. 3, step S102 includes:

S1022. In a case where it is determined that there is no uplink transmission in the second CG during the transmission of the target uplink transmission in the first CG, it is determined that the ratio of the transmission power occupied by the uplink transmission in the first CG to the maximum transmission power is 1.

In a third implementation manner, when the power control parameter includes the required power for uplink transmission in the first cell group CG, the high power ratio of the first CG, the required power for uplink transmission in the second CG, and the high power of the second CG For the proportion, as shown in FIG. 4, step S102 includes:

S1023. The required power for uplink transmission in the first CG is greater than the power indicated by the high power ratio of the first CG, and the required power for uplink transmission in the second CG is greater than the high power of the second CG. In the case of the power indicated by the power ratio, determining that the ratio of the transmission power occupied by the uplink transmission in the first CG to the maximum transmission power is the high power ratio of the first CG, and determining the uplink in the second CG The ratio of the transmitted transmission power to the maximum transmission power is the high power ratio of the second CG.

A fourth implementation manner, when the power control parameters include the required power for uplink transmission in the first cell group CG, the high power ratio of the first CG, the required power for uplink transmission in the second CG, and the high power of the second CG When the ratio is the low power ratio of the second CG, as shown in FIG. 5, step S102 includes:

S1024. The required power for uplink transmission in the first CG is greater than the power indicated by the high power ratio of the first CG, and the required power for uplink transmission in the second CG is less than that of the second CG. In the case of the power indicated by the power ratio, the maximum ratio of the maximum transmission power occupied by the transmission power of the uplink transmission in the first CG is determined as: 1-max (the required power of the uplink transmission in the second CG accounts for the maximum transmission Power ratio, low power ratio of the second CG).

It should be noted that max (x, y) means the one with the largest median value of x and y. Low power ratio) refers to the largest one of the two parameters of the required power for uplink transmission in the second CG and the low power ratio of the second CG.

The above four implementation manners provide specific implementation solutions for determining the transmission power of uplink transmission in the first CG. It should be noted that the transmission power of uplink transmission in the first CG here refers to the sum of the transmission power of all uplink transmissions in the first CG.

Further, in combination with the foregoing method flow, in the above four implementation manners, the low power ratio of the second CG is determined according to the attribute parameter of the target uplink transmission in the first CG, and the target uplink transmission in the first CG is determined. The attribute parameters include at least one of transmission duration, transmission service type, transmission priority, and channel / signal priority.

The proportion of low power of the second CG is directly proportional to the transmission duration of the target uplink transmission in the first CG, that is, the longer uplink transmission in the first CG needs to be reserved for the uplink transmission in the second CG. The transmission power of the second CG is relatively large.

It should be noted that, when considering sending power reserved for possible uplink transmission in the second CG, URLLC is allowed to occupy more sending power of the second CG than eMBB (Enhance Mobile Broadband, Enhanced Mobile Broadband), that is, high priority The service makes the low-power share of the second CG small.

It should also be noted that when considering the transmission power reserved for possible uplink transmission in the second CG, high priority channels / signals are allowed to occupy more transmission power of the second CG than low priority channels / signals, that is, high priority The level channel / signal makes the low power share of the second CG small.

It is further explained that the UE needs to occupy a certain transmission power when sending the uplink transmission, and the transmission power cannot exceed the limit of the maximum transmission power. For multiple uplink transmissions with a number greater than 1, when the time domain overlap occurs, the condition that the sum of the powers of the multiple uplink transmissions is not greater than the maximum transmit power is required. Time domain overlap may refer to multiple uplink transmissions sharing all or part of a period of time, including but not limited to the following multiplexing modes: frequency division multiplexing, code division multiplexing, and space division multiplexing.

Further, in combination with the foregoing method flow, the power control parameter further includes a sub-required power of each uplink transmission in the first CG and a sub-required power of each uplink transmission in the second CG. It should be explained that the sub-required power of each uplink transmission here refers to the respective required power of each uplink transmission. In order to distinguish it from the sum of the required power of all uplink transmissions (that is, the required power of uplink transmission in step S101), it is referred to here For the sub-demand power, and for the sub-transmit power in the following, a similar explanation is made.

Similarly, the information used to determine the sub-required power of each uplink transmission in the first CG and the information used to determine the sub-required power of each uplink transmission in the second CG are still configured by the base station for the UE.

Further, in combination with the foregoing method flow, when the required power for uplink transmission in the first CG is less than or equal to the transmission power for uplink transmission in the first CG, another possible implementation manner of the embodiment of the present disclosure, The following method flow is provided for determining the sub-transmitting power of the target uplink transmission in the first CG, which is performed after step S102, as shown in FIG. 6, including:

S103. Determine the sub-requested power of the target uplink transmission in the first CG as the sub-transmit power of the target uplink transmission in the first CG.

Further, in combination with the foregoing method flow, the required power for uplink transmission in the first CG may be greater than the transmission power for uplink transmission in the first CG, that is, when the total power of all uplink transmissions in the first CG is insufficient for allocation, the present Another possible implementation manner of the disclosed embodiment uses the priority to which each uplink transmission belongs as a reference attribute, and also provides the following method flow for determining the sub-transmission power of the target uplink transmission in the first CG, which is executed after step S102 , As shown in Figure 7, including:

S104. Allocate sub-transmission power for each uplink transmission in the first CG according to the priority of each uplink transmission in the first CG.

The specific implementation process of step S104 may include the following steps:

S1041. If there is a high-priority uplink transmission that overlaps with the target uplink transmission in the first CG in a time domain, first allocate a sub-transmission power of the high-priority uplink transmission.

After allocating the sub-transmission power of the high-priority uplink transmission,

S1042A. If there is no remaining transmission power for uplink transmission in the first CG, determine that the sub-transmission power of the target uplink transmission in the first CG is 0.

S1042B. If there is a surplus in the transmission power of the uplink transmission in the first CG, and there is an uplink transmission of the same priority as the target uplink transmission in the first CG with time domain overlap, according to the sub transmission power of the uplink transmission of the same priority Determine the situation, and allocate the sub-transmission power of the target uplink transmission in the first CG.

The determination of the sub-transmission power of uplink transmission of the same priority includes two cases in which the sub-transmission power of uplink transmission of the same priority has been determined and not determined.

When the remaining power of the transmission power of the uplink transmission in the first CG is insufficient to transmit all uplink transmissions of the same priority: if the sub-transmission power of the uplink transmission of the same priority has been determined, When the sub-transmission power is preferentially allocated, the sub-transmission power of the target uplink transmission in the first CG is redistributed; if the sub-transmission power of the uplink transmission of the same priority is not determined, the sub-transmission power in the first CG is reduced proportionally. The target uplink transmission and the sub-transmission power of the same priority uplink transmission to finally allocate the sub-transmission power of the target uplink transmission in the first CG, or determine the sub-transmission power of the same priority uplink transmission specified therein as 0, To finally allocate the sub-transmission power of the target uplink transmission in the first CG. It should be noted that, when the sub-transmission power of the uplink transmission of the same priority is not determined, if the remaining power of the transmission power of the uplink transmission in the first CG is insufficient to transmit all uplink transmissions of the same priority, The uplink transmission of the same priority may be allocated first with the shortest time occupied by the transmission and / or the transmission start time is recent and / or transmission has been started and accounts for the lowest proportion of the total transmission time of the local schedule. It is further explained that the rule of uplink transmission of the same priority that first allocates the shortest time occupied by the transmission and / or the transmission start time is the most recent and / or has started transmission and accounts for the lowest proportion of the total transmission time of the local schedule, can also be specified in the same After the sub-sending power of the priority uplink transmission is determined to be 0, the rule of the transmission of the same priority is used when reassigning.

Further, another possible implementation method of the embodiment of the present disclosure provides a method for determining the sub-sending power of each uplink transmission in the first CG according to the foregoing steps S104, S1041, S1042A, S1042B and other related steps, and further provides: A specific implementation process:

If there are multiple uplink transmissions that overlap with the target uplink transmission in the first CG with a time domain, at least one item is selected in order from the following to determine or reserve the sub-transmission power of each uplink transmission in the first CG:

(1) First allocate sub-required power for uplink transmissions having a priority higher than the target uplink transmission in the first CG;

(2) allocating sub-transmission power to uplink transmissions whose sub-transmission power has been determined in the uplink transmission having the same priority as the target uplink transmission in the first CG;

(3) Allocate the sub-transmission power of multiple uplink transmissions with the same priority and determine the sub-transmission power at the same time in one of the following ways: 1) transmission time from short to long, 2) transmission start time from morning to night, 3) Reduce the sub-transmission power of the multiple uplink transmissions proportionally, 4) Reduce the sub-transmission power of some uplink transmissions among the multiple uplink transmissions proportionally, and determine the sub-transmission power of the remaining uplink transmissions as 0.

It should be emphasized that steps (1), (2), and (3) are performed in order. When several uplink transmissions related to the current step are found in order, this is subtracted from the transmission power of the first CG. The transmission power required for several uplink transmissions in the step.

And before each step is performed, it is determined whether the remaining transmission power of the first CG can meet the power requirement of the target uplink transmission. If it can be satisfied, the target uplink transmission is allocated its required power as the determined sub-sending power. If it cannot be satisfied, the target uplink transmission is allocated the remaining power as the determined sub-sending power. If there are multiple uplink transmissions for which the sub-sending power is determined at the same time, when the remaining power in the first CG is insufficient to meet the power requirements of these uplink transmissions for which the sub-sending power is determined at the same time, then follow steps 1), 2), 3), 4) It is judged that power required for uplink transmission may be allocated one by one, or power scaling may be performed in proportion. When power reduction is performed in proportion, one or more of the sub-transmission powers of uplink transmission is allowed to be zero.

Further, in combination with the foregoing method flow, when the total power of all uplink transmissions in the first CG is insufficiently allocated, another possible implementation manner of the embodiment of the present disclosure takes into consideration factors such as the special priority and the sub-transmit power determination time. To determine the sub-transmission power of the target uplink transmission in the first CG, the following two different implementation methods are also provided, which are performed after step S102.

The first implementation method includes:

S105. If there are multiple uplink transmissions that overlap with the target uplink transmission in the first CG with a time domain, at least one item is selected in order from the following to determine or reserve the sub-transmission power of each uplink transmission in the first CG. :

(1) Allocating the sub-transmission power of the special priority uplink transmission according to the sub-required power of the special priority uplink transmission;

(2) Allocate sub-transmission power for uplink transmission for which sub-transmission power has been determined;

(3) Allocate multiple uplink transmissions that determine the sub-sending power at the same time as the target uplink transmission in the first CG according to the priority from the highest to the lowest;

(4) Allocate the sub-transmit power of multiple uplink transmissions with the same priority and determine the sub-transmit power at the same time in at least one of the following ways: 1) the transmission time is short to long, 2) the transmission start time is from morning to night, 3) Reduce the sub-transmission power of the multiple uplink transmissions proportionally, 4) Reduce the sub-transmission power of some uplink transmissions among the multiple uplink transmissions proportionally, and determine the sub-transmission power of the remaining uplink transmissions as 0.

In the first implementation method, transmission with a special priority is guaranteed first, and the allocation criteria of the sub-transmitting power for the remaining uplink transmissions are determined first. The sub-transmitting power is not determined and the sub-transmitting power is determined simultaneously with the target uplink transmission. Multiple uplink transmissions of the highest priority from the lowest to the lowest, while determining the same sub-transmission power and the same priority are reduced by the transmission time or proportionally (allows the specified sub-transmission power of the uplink transmission to be 0).

The second implementation method includes:

S106. If there are multiple uplink transmissions that overlap with the target uplink transmission in the first CG with a time domain, select at least one item in order from the following order to determine or reserve the sub-transmission power of each uplink transmission in the first CG. :

(1) Allocating the sub-transmission power of the special priority uplink transmission according to the sub-required power of the special priority uplink transmission;

(2) Allocate sub-transmission power for uplink transmission for which sub-transmission power has been determined;

(3) Allocate sub-transmission power of multiple uplink transmissions whose sub-transmission power is not determined according to the priority from high to the bottom;

(4) Allocate the sub-transmit power of multiple uplink transmissions with the same priority and determine the sub-transmit power at the same time in at least one of the following ways: 1) the transmission time is short to long, 2) the transmission start time is from morning to night, 3) Reduce the sub-transmission power of the multiple uplink transmissions proportionally, 4) Reduce the sub-transmission power of some uplink transmissions among the multiple uplink transmissions proportionally, and determine the sub-transmission power of the remaining uplink transmissions as 0.

In the second implementation method, transmission of a special priority is first guaranteed, and the allocation criteria of the sub-transmitting power of the remaining uplink transmissions are: first-come-first-served power is determined, and multiple uplink transmissions of un-determined sub-transmitting power are transmitted in order of priority from high to high. Low reservation, multiple uplink transmissions with the same priority as the target uplink transmission and at the same time determining the sub-transmission power are reduced according to the transmission time or proportionally (allowing the specified sub-transmission power for the uplink transmission to be 0).

It should be emphasized that steps (1), (2), (3), and (4) are performed in order. When several uplink transmissions related to the current step are found in order, the transmission power from the first CG The transmission power required for several uplink transmissions in this step is subtracted from.

And before executing each step, it is determined whether the remaining transmission power of the first CG can meet the power requirement of the target uplink transmission. If it can be satisfied, the target uplink transmission is allocated its required power as the determined sub-sending power. If it cannot be satisfied, the target uplink transmission is allocated the remaining power as the determined sub-transmission power. If there are multiple uplink transmissions for which the sub-sending power is determined at the same time, when the remaining power in the first CG is insufficient to meet the power requirements of these uplink transmissions for which the sub-sending power is determined at the same time, then follow steps 1), 2), 3), 4) It is judged that power required for uplink transmission may be allocated one by one, or power scaling may be performed in proportion. When power reduction is performed in proportion, one or more of the sub-transmission powers of uplink transmission is allowed to be zero.

It is further emphasized that, for the above two implementation methods, in steps (1), (2), (3), and (4), only after the previous steps are performed, can the transmission power of the first CG have remaining power. Determine the following steps. If there is no remaining power, the target uplink transmission power in the first CG is determined to be 0. In addition, when performing the power allocation specified in the above order on multiple uplink transmissions, it is not necessary to make all judgments. As long as the target uplink transmission is determined with the sub-transmission power, the remaining steps may not be performed. For example, the target uplink transmission has a special priority, and only step (1) is needed.

Further, in combination with the foregoing method flow, the sub-transmission power of the target uplink transmission in the first CG is usually determined at a specified time or before the specified time. The specified time is based on the start time of the target uplink transmission in the first CG, or according to the sending time of the target uplink transmission authorization information in the first CG, or according to the target uplink transmission authorization information in the first CG. The receiving moment is OK.

The specified time is a time shifted forward by a specified time difference from a start time of the target uplink transmission in the first CG, or the specified time is shifted backward by a time of sending authorization information of the target uplink transmission in the first CG Shifting the time of the specified time difference, or shifting backward the time of the specified time difference from the reception time of the target uplink transmission authorization information in the first CG.

The time difference includes a predefined value, a configured cell-specific value, a configured first CG specific value, a sender-specific value of a target uplink transmission in the configured first CG, and a time determined by a scheduling processing delay K2 of the uplink transmission. And at least one of the amount of time determined by the minimum processing delay N2 parameter of the uplink transmission.

The predefined value is a fixed value stipulated by the standard, for example, 3 OFDM symbols.

The configured cell-specific value can be used for all UEs, that is, all UEs in the cell share the configured value.

The first CG specific value configured refers to the first CG specific configuration value, and the specific values of MCG and SCG are configured separately.

Wherein, the sender (ie, UE) specific value of the configured first CG transmission, that is, the time difference is a UE-specific (UE specific) configuration value.

The K2 value of the target transmission in the first CG refers to the scheduling processing delay of the uplink transmission. Specifically, the slot occupied by the DCI (Downlink Control Information) that contains UL grant information for a PUSCH transmission can be transmitted to the PUSCH transmission. The difference between the occupied slots. Further, the time difference between the specified time and the transmission start time of the target uplink transmission in the first CG may be the minimum value of the configured K2 value, or an indication value of the configured K2 value (the base station configures multiple values for the UE). K2 values, K2 used for each uplink transmission is further indicated by the physical layer information, and the time difference between the specified time and the transmission start time of the target uplink transmission in the first CG is equal to the K2 value determined for the current transmission), or (The number of K2 slot symbols, N2 symbols) (where N2 is the minimum processing delay for the UE to process uplink transmission, and the unit is OFDM symbols).

It should be noted that the specified time is sent to the terminal after the base station is configured. Generally, the base station configures specific time difference parameters, such as a predefined value or a configured cell-specific value or a configured first CG specific value or a configured sender-specific value of a target uplink transmission in the configured first CG or an uplink transmission scheduling process. The amount of time determined by the delay K2 or the amount of time determined by the minimum processing delay N2 parameter of the uplink transmission.

Further, in combination with the foregoing method flow, after determining the sub-transmission power of the target uplink transmission in the first CG, in order to update the sub-required power of the target uplink transmission in the first CG, another possible embodiment of the present disclosure The implementation also provides the following method flow, including:

S107. After the specified time, update the sub-requested power of the target uplink transmission in the first CG to the determined sub-transmission power value of the target uplink transmission in the first CG.

After determining the sub-transmission power of the target uplink transmission in the first CG, the sub-required power of the target uplink transmission in the first CG may be updated to the determined sub-transmission power of the target uplink transmission in the first CG. value.

It should be noted that before determining the sub-transmitting power moment of the target uplink transmission in the first CG, the sub-required power of the target uplink transmission in the first CG is the original sub-required power, that is, using open loop, closed loop, The power calculated by parameters such as PL (Pathloss, Path Loss, Path Loss for short) is limited by not exceeding the maximum transmission power.

It is further explained that before the sending of the target uplink transmission in the first CG is completed, the sub-required power of the target uplink transmission in the first CG will also be updated according to the power preemption of the high-priority uplink transmission.

Further, in combination with the foregoing method flow, the priorities of uplink transmission in the first CG include special priorities and non-special priorities. Specifically, transmission with a special priority may include transmission of URLLC with a service type of ultra-high reliability and ultra-low latency communication, transmission of control type information of URLLC services, transmission identified as a special scheduling type, and identification as a special scheduling type At least one of transmission of control-type information, transmission of power required to be identified as preempting uplink transmission in other CGs, and physical random access channel PRACH. Non-special priorities are priorities other than special priorities.

The special priority is higher than the priority of the PUCCH carrying Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information and / or service router (SR) information; among the special priorities, the priority of PRACH is The priority is higher than the priority of the remaining special priority transmissions; or, in the same priority, the priority of the primary CG transmission is higher than that of the secondary CG transmission.

The sub-demand power allocation method for uplink transmissions that belong to a special priority follows the following principles: When the target uplink transmission in the first CG belongs to a transmission with a special priority, and the first CG is the primary CG, the first CG in the first CG The ratio of the maximum allowed sub transmission power to the maximum transmission power of the target uplink transmission is 1; when the target uplink transmission in the first CG belongs to a transmission with a special priority, and the first CG is a secondary CG, the first CG The ratio of the maximum allowed sub-transmission power to the maximum transmission power in the target uplink transmission is: 1- The ratio of the power of the uplink transmission of the special priority in the main CG.

In addition, when the target uplink transmission in the first CG belongs to a transmission of a special priority class, the sub-demand power of the low priority transmission in the first CG and / or the second CG may be occupied; when the target uplink transmission in the first CG is When the transmission belongs to the non-special priority class, the sub-required power of the low-priority transmission in the first CG may be occupied.
