Description

Power control method, device, electronic equipment and storage medium

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a power control method, apparatus, electronic device, and storage medium.

Background

In order to make full use of resources for transmission of two or more types of data with different priorities, for example, when Enhanced Mobile Broadband (eMBB) data already occupies all transmission resources and Ultra-reliable Low Latency Communication (URLLC) data needs to be transmitted, power for URLLC data transmission may be increased, so that the data may be transmitted on the resources already occupied by the eMBB. That is, two or more sets of power control parameter sets are configured for the PUSCH of URLLC data transmission, and are used when URLLC data is transmitted on idle resources or on resources occupied by the eMBB, respectively.

In order to meet the requirement of low-delay characteristic for transmitting high-priority data, a Physical Uplink Shared Channel (PUSCH) of a non-scheduled (GF, grant-free, PUSCH also referred to as a configured PUSCH, that is, a PUSCH not scheduled to be transmitted by DCI) is used for transmission of Uplink data. However, high priority data is not required to be transmitted at every time of the grant-free PUSCH, and in actual applications, there are times when data is transmitted and there are times when no data is transmitted for the grant-free PUSCH, as shown in fig. 1. At the time of no data transmission, the User Equipment (UE) does not transmit PUSCH, and PUSCH resources of grant-free are idle. In order to make full use of resources, it is preferable to transmit data of low priority when there is no data of high priority to be transmitted, so that the data can be transmitted by making full use of the resources.

When the PUSCH for transmitting high-priority data is transmitted on idle resources, the interference on the PUSCH is small, and the performance is easily ensured, at this time, the power control for PUSCH transmission may employ a power control parameter set P-set 1. When the PUSCH for transmitting high-priority data is transmitted on the PUSCH for transmitting low-priority data, the PUSCH is subjected to additional interference, which is relatively large, and performance is not easily guaranteed. To achieve the same performance as when not interfered by PUSCH transmitting low priority data, the additional interference experienced may be cancelled by increasing the transmit power of PUSCH transmitting high priority data, at which time the power control of the PUSCH transmission may employ the power control parameter set P-set 2. The transmission power of the PUSCH calculated using the power control parameter set P-set2 is greater than the transmission power of the PUSCH calculated using the power control parameter set P-set1, as shown in FIG. 2.

When high-priority data is transmitted through grant-free PUSCH, which is not scheduled through Downlink Control Information (DCI), a solution is needed how a UE knows that the PUSCH is idle or has transmitted low-priority data when the UE intends to transmit high-priority data through grant-free PUSCH.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

An embodiment of the present application provides a power control method, as shown in fig. 3, the method includes:

step S301: receiving resource occupation indication information, wherein the resource occupation indication information is used for indicating the resource occupation condition of second priority data on a PUSCH (physical uplink shared channel) used for transmitting first priority data;

step S302: determining the resource occupation condition of a PUSCH (physical uplink shared channel) for transmitting the first priority data according to the resource occupation indication information;

step S303: determining the power of a PUSCH (physical uplink shared channel) for transmitting the first priority data according to the resource occupation condition of the PUSCH for transmitting the first priority data;

The execution main body of the method may be a UE or a functional module of the UE, and the following embodiments take the UE as an example for description.

In step S301 in this embodiment of the present application, the UE receives resource occupation indication information. In step S302, according to the resource occupation indication information, determining the resource occupation of the PUSCH for transmitting the first priority data, and determining whether the resource of the PUSCH for transmitting the first priority data is an idle resource or a PUSCH resource which has transmitted the second priority data.

In one possible implementation, the resource occupancy indication information may indicate which resources are PUSCH resources on which the second priority data has been transmitted. That is, the UE determines which resources have transmitted the second priority data through the received resource occupation indication information.

In another possible implementation, the resource occupation indication information may indicate which resources are idle resources. That is, the UE may determine which resources do not transmit the second priority data through the received resource occupancy indication information.

Then, in step S303, the UE may determine the power of the PUSCH for transmitting the first priority data according to whether the determined resource of the PUSCH for transmitting the first priority data is an idle resource or a PUSCH resource which has transmitted the second priority data, for example, determine an adopted power control parameter set, and determine the corresponding power according to the determined power control parameter set, so as to perform power control on the PUSCH for transmitting the first priority data according to the determined power.

According to the power control method provided by the embodiment of the application, through the indication of the resource occupation indication information, whether the resource occupation condition of the PUSCH used for transmitting the high-priority data is idle or the low-priority data is transmitted can be determined, and then the power of the PUSCH used for transmitting the high-priority data is determined according to the determined source occupation condition, so that the power control is performed on the PUSCH, the reliability of the high-priority data transmission can be ensured, and the power can not be wasted.

The present inventors further realized that after receiving the resource occupation indication information, the UE still needs to solve the problem of how to determine which time unit the resource occupation indication information indicates, and a feasible solution is provided below.

In the embodiment of the application, through a timing relationship, the UE receiving the resource occupation indication information can know which time unit the resource occupation indication information corresponds to. As an example, the time unit occupied by the transmission of the resource occupation indication information (the time unit may be one slot or one or more OFDM symbols) is n-k, that is, the resource occupation indication information is transmitted in the n-k time unit, the resource occupation indication information describes the resource occupation condition of the PUSCH of the time unit n, and determining the timing relationship is determining the k value (also referred to as a time interval).

Specifically, step S302 may include the steps of:

step Sa: and determining a timing relation between a first time unit and a second time unit, wherein the first time unit is a time unit occupied by transmission resource occupation indication information, and the second time unit is a time unit occupied by PUSCH resources corresponding to the resource occupation condition indicated by the resource occupation indication information.

And Sb: and determining the resource occupation condition of the PUSCH for transmitting the first priority data according to the timing relation and the resource occupation indication information.

Each time unit may be one time slot, or multiple time slots, or one OFDM (Orthogonal Frequency Division Multiplexing) symbol, or multiple OFDM symbols.

In the embodiment of the present application, the resource occupation indication information may be transmitted through DCI, or may be transmitted through one sequence. The following description will take the resource occupation indication information through DCI transmission as an example. In practical applications, one DCI may provide transmission resource occupation indication information for a plurality of UEs, and the resource occupation indication information is transmitted through a UE group-common DCI.

In step Sa, the first time unit is a time unit occupied by transmitting the resource occupation indication information, and may also be considered as a time unit for transmitting DCI of the UE group-common resource occupation indication information;

the second time unit is a time unit occupied by the PUSCH resource corresponding to the resource occupation condition indicated by the resource occupation indication information, that is, the resource occupation indication information needs to indicate whether the resource occupation condition is idle or the PUSCH occupied by which the second priority data has been transmitted.

Wherein the first time unit and the second time unit only represent the distinction of the time units of the two resources and are not to be understood as the definition of the time unit order or value.

According to the determined timing relationship between the first time unit and the second time unit, after receiving the DCI for transmitting the UE group-common resource occupation indication information, the UE can know which time unit is described by the resource occupation indication information for transmitting the PUSCH of the first priority data, so that the resource occupation situation of the PUSCH for transmitting the first priority data can be determined by the resource occupation indication information, so as to subsequently determine and adjust the transmission power of the PUSCH, as shown in fig. 4.

In this case, how the UE obtains the timing relationship between the first time unit and the second time unit is described below.

In an embodiment of the present application, a method for determining a timing relationship between a first time unit and a second time unit includes: directly obtaining a timing relation according to the received signaling; or, a preset timing relationship is directly obtained.

Specifically, in the first method, the UE may obtain the timing relationship according to the received explicit signaling and/or implicit signaling, or obtain the timing relationship preset by the protocol.

The explicit signaling includes, but is not limited to, system information, higher layer signaling, medium access layer signaling, or physical layer signaling.

In an example of the first method, the UE obtains the timing relationship between the first time unit and the second time unit by receiving an explicit signaling (e.g., signaling with slow change such as system information, higher layer signaling, media access layer signaling, etc.) sent by the base station, that is, the UE obtains a value k by receiving the explicit signaling sent by the base station, where k is an integer greater than or equal to 0. When the value k is configured through high-layer signaling, the value k can be configured through common high-layer signaling or through UE-specific high-layer signaling. The k value may be the same for different UEs in a group, which may allow for more convenient transmission in TDD (Time Division Duplexing) situations.

In another example of the first method, the UE determines the k value in a manner preset by a protocol, and the k value is the same for different UEs.

In another example of the first method, the UE obtains the timing relationship between the first time unit and the second time unit by receiving an implicit signaling sent by the base station, that is, the UE obtains a value k by receiving the implicit signaling sent by the base station, where k is an integer greater than or equal to 0. In one possible implementation, assuming that the UE has configured a set of timing relationships k2 between DCI scheduling a PUSCH and the DCI scheduled PUSCH, the value of the timing relationship k between the first time unit and the second time unit is one of the set of timing relationships k2 (e.g., the minimum value or the maximum value, etc.). For example, if the set of timing relationships k2 for a UE is {1,2,3,4}, and the minimum value in the set of timing relationships k2 is 1, the value of the timing relationship k between the first time unit and the second time unit for the UE is 1.

The method is easy to implement and requires relatively low signaling overhead. In consideration of the situation that the PUSCH for transmitting the first priority data includes the PUSCH which cannot determine the resource occupation situation according to the resource occupation indication information in some cases, that is, some uplink time units cannot perform the resource occupation situation indication. For example, in the case of an asymmetric spectrum, when the number of uplink time units and downlink time units is not equal, for example, there are 2 downlink time units and 8 uplink time units in 10 time units, and k is equal to 4, the resource occupation status of some uplink time units cannot be indicated, as shown in fig. 5.

In the embodiment of the present application, the method that can be adopted for this is: and determining the resource occupation condition of the specific PUSCH as the resource occupation condition of the PUSCH which cannot determine the resource occupation condition according to the resource occupation indication information. In short, the resource occupation situation of the PUSCH of the uplink time unit without the resource occupation indication information may be considered to be the same as the resource occupation situation of the PUSCH of the specific uplink time unit. In a feasible implementation manner, the resource occupation situation of the PUSCH of the uplink time unit without the resource occupation indication information may be considered to be the same as the resource occupation situation of the PUSCH of the uplink time unit with the latest previous resource occupation indication. In the above example, in the case of an asymmetric spectrum, when the number of uplink time units is not equal to that of downlink time units, if there are 2 downlink time units, 8 uplink time units, and k is equal to 4 in 10 time units, the resource occupancy indication information of the downlink time unit 0 indicates the resource occupancy of the PUSCH of the uplink time unit 4, and the resource occupancy indication information of the downlink time unit 5 indicates the resource occupancy of the PUSCH of the uplink time unit 9. At this time, the resource occupancy of the PUSCH of the

uplink time unit

1,2,3 may be determined to be the same as the resource occupancy of the PUSCH of the indicated uplink time unit that is the latest before the uplink time unit 1, and the resource occupancy of the PUSCH of the

uplink time unit

6,7,8 may be determined to be the same as the resource occupancy of the PUSCH of the indicated uplink time unit 4 that is the latest before the uplink time unit 6, as shown in fig. 6.

In the embodiment of the present application, in order to determine the timing relationship more flexibly, the timing relationship is obtained in a dynamic manner by the second method.

Specifically, in the second method, the UE obtains a timing relationship set and timing relationship indication information according to the received signaling; and obtaining the timing relationship according to the timing relationship set and the timing relationship indication information.

Wherein the received signaling is explicit signaling and/or implicit signaling. Explicit signaling includes, but is not limited to, system information, higher layer signaling, medium access layer signaling, or physical layer signaling, etc.

In this embodiment of the present application, the received signaling includes a first sub signaling and a second sub signaling, for example, the first sub signaling is explicit signaling (for example, system information or higher layer signaling), the second sub signaling is another explicit signaling (for example, physical layer signaling), or the first sub signaling is implicit signaling, and the second sub signaling is explicit signaling. Those skilled in the art can appropriately expand the scope of the present application based on these examples.

Specifically, a timing relationship set is obtained according to a received first sub-signaling; and obtaining a timing relation according to the received second sub-instruction corresponding to the resource occupation indication information.

By way of example, through explicit signaling (or implicit signaling) and physical layerThe value of k is obtained by means of signaling combination, and k is an integer greater than or equal to 0. Taking the explicit signaling as an example, the UE obtains a timing relationship set (which may also be referred to as a resource occupation indication information timing relationship set, and the same parts are not described in detail below) through the explicit signaling (e.g., system information, higher layer signaling). For example, the set of timing relationships is k₀，k₁，k₂，k₃}. A specific time interval value (i.e., k value) in the set is then indicated by physical layer signaling. Illustratively, the timing relation indication information is a timing relation indication value which is related to the timing relation k_iThe correspondence of (a) is shown in table 1.

Timing relationship indicator value	Timing relationship k_i
		00	k₀
01	k₁
		10	k₂
11	k₃

TABLE 1

The following describes the manner of determining the timing relationship set and indicating a specific time interval value (timing relationship) in the set through physical layer signaling in several second methods.

In a feasible implementation, the UE passes through the displayThe timing relationship set is obtained by formula signaling (e.g., system information, higher layer signaling configuration, where the higher layer signaling configuration may be UE-specific higher layer signaling configuration or UE common higher layer signaling configuration), where the timing relationship sets corresponding to the resource occupation indication information transmitted in the DCI transmitting the same UE group-common resource occupation indication information are the same. For example, the set of timing relationships is k₀，k₁，k₂，k₃}. In addition to transmitting the resource occupation indication information in the DCI transmitting the UE group-common resource occupation indication information, one timing relationship indication information (e.g., a timing relationship indication value) may be transmitted to indicate one value in a timing relationship set as a timing relationship k between a first time unit and a second time unit_i. For example, the information in the DCI transmitting the UE group-common resource occupancy indication information is { resource occupancy indication information, timing relationship indication value }, where an information field of the timing relationship indication value includes L bits (e.g., L is 2), and a timing relationship k between the first time unit and the second time unit_iThe correspondence of (a) is shown in table 1.

In another possible implementation manner, the UE obtains the timing relationship set through implicit signaling (for example, the timing relationship set may be a timing relationship set k2 between DCI for scheduling a PUSCH configured by UE common higher layer signaling and a PUSCH scheduled by the DCI), where the timing relationship sets corresponding to resource occupancy indication information transmitted in the DCI for transmitting the same UE group-common resource occupancy indication information are the same. For example, k2 has a set of timing relationships { k2 }₀，k2₁，k2₂，k2₃}. In addition to transmitting the ue group-common resource occupancy indication information, a specific timing relationship indication information (e.g., timing relationship indication value) is transmitted to indicate one of the sets of timing relationships k2 as the timing relationship k between the first time unit and the second time unit_i. For example, the information in the DCI transmitting the UE group-common resource occupancy indication information is { resource occupancy indication information, timing relationship indication value }, where an information field of the timing relationship indication value includes L bits (e.g., L is 2), and the first information field includes L bitsTiming relationship k between a time unit and a second time unit_iThe correspondence of (2) is shown in Table 2.

Timing relationship indicator value	Timing relationship k2_i
		00	k2₀
01	k2₁
		10	k2 ₂
11	k2₃

TABLE 2

Alternatively, the timing relation set obtained by implicit signaling is a set composed of a part of elements in the timing relation set k2, for example, the timing relation set k2 includes 4 elements, k2 is { k2₀，k2₁，k2₂，k2₃The set of timing relationships obtained by implicit signaling is a set consisting of the first two elements in the k2 set, and is { k2 }₀，k2₁}。

In the embodiment of the application, the determination mode of the timing relationship can be obtained according to default configuration or received high-level signaling; and determining the timing relation based on the obtained determination mode. The determination mode of the timing relationship comprises the first method and the second method.

That is, the method for determining the timing relationship between the first time unit and the second time unit may be configured by a higher layer signaling according to the first method or the second method. If the UE does not receive the configuration of the higher layer signaling by using the first method or the second method, the UE may determine the timing relationship between the first time unit and the second time unit by using a default method of the first method and the second method, for example, the first method is a default method.

In this embodiment of the present application, step S303 may specifically include the following implementation manners:

if all resources of the PUSCH used for transmitting the first priority data are idle resources, determining the first power as the power of the PUSCH used for transmitting the first priority data;

if all resources of the PUSCH used for transmitting the first priority data are occupied resources of the PUSCH used for transmitting the second priority data, determining the second power as the power of the PUSCH used for transmitting the first priority data;

and if a part of the resources of the PUSCH used for transmitting the first priority data are occupied resources of the PUSCH used for transmitting the second priority data, and the other part of the resources are idle resources, determining the power of the PUSCH used for transmitting the first priority data according to a preset mode.

Wherein the first power is less than the second power.

As an example, the first power is a transmission power of PUSCH calculated with the power control parameter set P-set1, and the second power is a transmission power of PUSCH calculated with the power control parameter set P-set 2.

For the case that a part of the resources of the PUSCH for transmitting the first priority data are occupied resources of the PUSCH for transmitting the second priority data, and another part of the resources are idle resources, as shown in fig. 7, the embodiments of the present application provide the following power control methods.

The method comprises the following steps: the second power is determined as a power of all resources of the PUSCH for transmitting the first priority data.

If the resource of the PUSCH for transmitting the first priority data is an idle resource, the power of the PUSCH should be relatively small, denoted as P1, and if the resource of the PUSCH for transmitting the first priority data is an occupied resource of the PUSCH for transmitting the second priority data, the power of the PUSCH should be relatively large, denoted as P2.

If a part of the resources of the PUSCH for transmitting the first priority data are occupied resources of the PUSCH for transmitting the second priority data, and another part of the resources are idle resources, at this time, the resources of the PUSCH for transmitting the first priority data may all use the relatively large power P2, that is, it is assumed that all the resources of the PUSCH for transmitting the first priority data are occupied resources of the PUSCH for transmitting the second priority data when determining the power, so that the resource powers of the PUSCHs are equal, and the reliability of the transmission of the first priority data can be ensured.

And determining the third power as the power of all resources of the PUSCH for transmitting the first priority data, wherein the third power is determined according to at least one of the first power, the second power, the PUSCH resource corresponding to the first power and the PUSCH resource corresponding to the second power.

If a part of the resources of the PUSCH for transmitting the first priority data are occupied resources of the PUSCH for transmitting the second priority data, and the other part of the resources are idle resources, at this time, the power of the PUSCH is calculated according to whether the resources of the PUSCH for transmitting the first priority data are occupied resources of the PUSCH for transmitting the second priority data or the idle resources, respectively. That is, when the resource of the PUSCH for transmitting the first priority data is the occupied resource of the PUSCH for transmitting the second priority data, the power of the partial resource is P2, and when the resource of the PUSCH for transmitting the first priority data is the idle resource, the power of the partial resource is P1, and then the occupied resource part, that is, the idle resource part, of the PUSCH for corresponding to P1 and P2 to the second priority data is averaged to obtain the power of the entire resource of the PUSCH for transmitting the first priority data. For example, the PUSCH for transmitting the first priority data includes 20 Physical Resource Blocks (PRBs), where resources of 10 PRBs are occupied resources of the PUSCH for the second priority data, the calculated power of each PRB is P2, the resources of 10 PRBs are idle resources, the calculated power of each PRB is P1, and the average method is: (10 × P1+10 × P2)/20 ═ P1+ P2)/2, and all PRBs use power, (P1+ P2)/2.

And thirdly, determining the power of all resources of the PUSCH for transmitting the first priority data according to the proportion of occupied resources and idle resources of the second priority PUSCH transmission in the resources of the PUSCH for transmitting the first priority data.

If a part of the resources of the PUSCH for transmitting the first priority data are occupied resources for transmitting the PUSCH of the second priority data, and another part of the resources are idle resources, at this time, the power of all the resources of the PUSCH for transmitting the first priority data may be determined according to the ratio of occupied resources to idle resources for transmitting the PUSCH of the second priority in the resources of the PUSCH for transmitting the first priority data, for example, if the ratio of occupied resources to idle resources for transmitting the PUSCH of the second priority in the resources of the PUSCH for transmitting the first priority data is greater than a threshold (denoted as th1), the second power is determined as the power of all the resources of the PUSCH for transmitting the first priority data, that is, all the resources of the PUSCH for transmitting the first priority data adopt a relatively large power P2. Otherwise, the first power is determined as the power of all resources of the PUSCH for transmitting the first priority data, that is, if the ratio of occupied resources of the PUSCH for second priority transmission to idle resources in the resources of the PUSCH for transmitting the first priority data is less than or equal to the threshold (denoted as th1), all resources of the PUSCH for transmitting the first priority data use a relatively small power P1.

The inventors of the present application found that, in order to satisfy the low latency characteristic of transmission of first priority data, when there is an overlap between the PUSCH for transmitting first priority data and the PUSCH for transmitting second priority data, the PUSCH for transmitting first priority data may replace the PUSCH for transmitting second priority data, as shown in fig. 8, the DCI for slot n-4 schedules PUSCH-1 for transmission in slot n, the DCI for slot n-2 schedules PUSCH-2 for transmission in slot n, PUSCH-2 and PUSCH-1 have an overlap, and PUSCH-2 has a higher priority than PUSCH-1, and thus PUSCH-2 is transmitted in slot n and PUSCH-1 is not transmitted in slot n, and then, in this case, that is, when there is an overlap between the PUSCH for transmitting first priority data and the PUSCH for transmitting second priority data, and the PUSCH for transmitting first priority data replaces the PUSCH for transmitting second priority data, a Power Headroom Report (PHR) may be determined according to a first Power control parameter of a PUSCH for transmitting first priority data that satisfies a delay requirement, and the determined PHR may be transmitted.

In general, the PHR may be determined according to one of a first power control parameter of a PUSCH for transmitting first priority data, a second power control parameter of a PUSCH for transmitting second priority data, and a default power control parameter, and the determined PHR may be transmitted.

Specifically, when the PUSCH for transmitting the first priority data satisfies the delay requirement (in this case, regardless of whether the PUSCH for transmitting the second priority data satisfies the delay requirement), the PHR is determined according to the first power control parameter;

when the PUSCH for transmitting the first priority data does not meet the time delay requirement and the PUSCH for transmitting the second priority data meets the time delay requirement, determining a PHR according to a second power control parameter;

and when the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data do not meet the time delay requirement, determining the PHR according to the default power control parameter.

It should be noted that, meeting the latency requirement means that a certain time is required before transmitting the PHR in the PUSCH to calculate the PHR according to the PUSCH power control parameter, that is, a preparation time is required, for example, when the PUSCH for transmitting the PHR starts at the mth OFDM symbol of the slot n and the processing latency is L OFDM symbols, the UE needs to know the PUSCH power control parameter for calculating the PHR before L OFDM symbols before the mth OFDM symbol of the slot n of the PUSCH for transmitting the PHR, so that the PHR can be calculated. If the UE knows the PUSCH power control parameter for calculating the PHR before L OFDM symbols before the mth OFDM symbol of the slot n of the PUSCH for transmitting the PHR, it is able to calculate the PHR according to the PUSCH power control parameter, which means that the PUSCH corresponding to the PUSCH power control parameter for calculating the PHR satisfies the latency requirement, and if the UE cannot know the PUSCH power control parameter for calculating the PHR before L OFDM symbols before the mth OFDM symbol of the slot n of the PUSCH for transmitting the PHR, it is unable to calculate the PHR according to the PUSCH power control parameter, which means that the PUSCH corresponding to the PUSCH power control parameter for calculating the PHR does not satisfy the latency requirement, as shown in fig. 9.

In the embodiment of the present application, whether the PUSCH for transmitting data meets the delay requirement includes at least one of the following determination manners:

determining a mode 1, if the PUSCH for transmitting data is configured, the PUSCH for transmitting data meets a delay requirement;

determining a mode 2, when the PUSCH for transmitting the PHR is configured and the PUSCH for transmitting the data is scheduled by the DCI, if the number of OFDM symbols spaced between the last orthogonal frequency division multiplexing OFDM symbol of the PDCCH which schedules the DCI for transmitting the data for the PUSCH and the PUSCH starting OFDM symbol for transmitting the PHR is not less than a predetermined value L, the PUSCH for transmitting the data satisfies a delay requirement, otherwise, the PUSCH for transmitting the data does not satisfy the delay requirement;

wherein the predetermined value L may be equal to Tproc,2, and the value L may be preset by the protocol.

Illustratively, the PUSCH for transmitting data is said to satisfy the latency requirement if the last OFDM symbol of the PDCCH scheduling DCI for PUSCH for transmitting data is 2 OFDM symbols earlier than the PUSCH start OFDM symbol Tproc for transmitting PHR, and the PUSCH for calculating PHR is said to not satisfy the latency requirement if the number of OFDM symbols of the PDCCH scheduling DCI for PUSCH for transmitting data is less than Tproc 2 OFDM symbols earlier than the PUSCH start OFDM symbol for transmitting PHR, as shown in fig. 10.

Determining a mode 3, when both the PUSCH for transmitting the PHR and the PUSCH for transmitting data are scheduled by DCI, if the end position of the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the data of the PUSCH is before the end position of the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the PHR, the PUSCH for transmitting the data satisfies a delay requirement, otherwise, the PUSCH for transmitting the data does not satisfy the delay requirement;

specifically, when both the PUSCH for transmitting the PHR and the PUSCH for transmitting data are scheduled by the DCI, the end position of the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the PUSCH for transmitting data is earlier than the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the PUSCH for PHR, the PUSCH for transmitting data satisfies the latency requirement, and the end position of the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the PUSCH for data is not earlier than the last OFDM symbol of the PDCCH scheduling the DCI for transmitting the PUSCH for PHR, the PUSCH for transmitting data does not satisfy the latency requirement, as shown in fig. 11.

It is to be understood that the above-mentioned PUSCH for transmitting data includes PUSCH for transmitting first priority data and/or PUSCH for transmitting second priority data.

The following describes whether the PUSCH for transmitting data satisfies the requirement of latency requirement in various situations, and a corresponding PHR calculation manner.

Case 1.1: the PUSCH for transmitting the PHR is configured (i.e., configured PUSCH), and the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data are scheduled by DCI.

In this case, it can be determined whether the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data satisfy the latency requirement by the determination method 2.

Optionally, it may be determined whether the PUSCH for transmitting the first priority data meets the delay condition first, if the PUSCH for transmitting the first priority data meets the delay requirement, the PHR is determined directly according to the first power control parameter, if the PUSCH for transmitting the first priority data does not meet the delay requirement, it is determined whether the PUSCH for transmitting the second priority data meets the delay condition, if the PUSCH for transmitting the second priority data meets the delay requirement, the PHR is determined according to the second power control parameter, and if the PUSCH for transmitting the second priority data does not meet the delay requirement, the PHR is determined according to the default power control parameter.

Optionally, it may be determined whether the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data satisfy the latency requirement at the same time, and then if both the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data satisfy the latency requirement, the PHR is determined according to the first power control parameter; if the PUSCH for transmitting the first priority data does not meet the delay requirement and the PUSCH for transmitting the second priority data meets the delay requirement, determining the PHR according to the second power control parameter; if the PUSCH for transmitting the first priority data meets the time delay requirement and the PUSCH for transmitting the second priority data does not meet the time delay requirement, determining a PHR according to the first power control parameter; and if the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data do not meet the time delay requirement, determining the PHR according to the default power control parameter.

Case 1.2: the PUSCH for transmitting PHR is configured, the PUSCH for transmitting first priority data is scheduled by DCI, and the PUSCH for transmitting second priority data is configured.

As can be seen from the determination method 1, since the PUSCH for transmitting the second priority data is configured, it can be considered that the delay requirement is always satisfied. In this case, it may be determined whether the PUSCH for transmitting the first priority data satisfies the delay requirement by the determination method 2.

If the PUSCH for transmitting the first priority data is determined to meet the time delay requirement, determining a PHR according to the first power control parameter; and if the PUSCH for transmitting the first priority data is determined not to meet the delay requirement, determining the PHR according to the second power control parameter.

Case 1.3: the PUSCH for transmitting PHR is configured, the PUSCH for transmitting first priority data is configured, and the PUSCH for transmitting second priority data is scheduled by DCI.

As can be seen from the determination method 1, since the PUSCH for transmitting the first priority data is configured, it can be considered that the delay requirement is always satisfied, and in this case, the PHR may be determined according to the first power control parameter.

Case 1.4: the PUSCH for transmitting PHR is configured, and the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data are both configured.

Similarly, as can be seen from the determination method 1, since the PUSCH for transmitting the first priority data is configured, it can be considered that the delay requirement is always satisfied, and in this case, the PHR may be determined according to the first power control parameter.

Case 2.1: the PUSCH for transmitting PHR, the PUSCH for transmitting first priority data, and the PUSCH for transmitting second priority data are all scheduled by DCI.

In this case, it can be determined whether the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data satisfy the latency requirement by the determination method 3 described above.

Case 2.2: the PUSCH for transmitting PHR is scheduled by DCI, the PUSCH for transmitting first priority data is scheduled by DCI, and the PUSCH for transmitting second priority data is configured.

As can be seen from the determination method 1, since the PUSCH for transmitting the second priority data is configured, it can be considered that the delay requirement is always satisfied. In this case, it may be determined whether the PUSCH for transmitting the first priority data satisfies the delay requirement by the determination method 3 described above.

Case 2.3: the PUSCH for transmitting PHR is scheduled by DCI, the PUSCH for transmitting first priority data is configured, and the PUSCH for transmitting second priority data is scheduled by DCI.

Case 2.4: the PUSCH for transmitting PHR is scheduled by DCI, and the PUSCH for transmitting first priority data and the PUSCH for transmitting second priority data are both configured.

By the PHR reporting mode under each condition, the PHR reporting can more accurately reflect the power use condition of the actual data to be transmitted, and the power can be more fully utilized.

Further, in order to satisfy the low latency characteristic of the transmission of the first priority data, when the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data overlap, the PUSCH for transmitting the first priority data may replace the PUSCH for transmitting the second priority data, for example, as shown in fig. 8, the DCI for slot n-4 schedules the PUSCH-1 for transmission in slot n, the DCI for slot n-2 schedules the PUSCH-2 for transmission in slot n, the PUSCH-2 and the PUSCH-1 overlap, and the PUSCH-2 has a higher priority than the PUSCH-1, so that the PUSCH-2 is transmitted in slot n and the PUSCH-1 is not transmitted in slot n, and then in this case, that is, when the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data overlap, and the PUSCH for transmitting the first priority data replaces the PUSCH for transmitting the second priority data, determining a PUSCH for determining a PHR from among a PUSCH transmitting first priority data and a PUSCH transmitting second priority data; and determining the PHR based on the determined power control parameter of the PUSCH for determining the PHR, and transmitting the determined PHR.

As can be seen from the above description, in determining the PHR using the power control parameter, an important point is to determine whether the power control parameter used in determining the PHR is the PUSCH for transmitting the first priority data or the PUSCH for transmitting the second priority data, and therefore, determining the PUSCH for determining the PHR from among the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data includes any one of the following first, second, third, and fourth modes:

the first method is as follows: and determining the PUSCH for determining the PHR according to the data transmission time of each PUSCH.

That is, as can be seen from the first embodiment, in the first embodiment, the PUSCH for determining the PHR may be determined according to the time when the PUSCH transmission data of the first priority data is transmitted and the time when the PUSCH transmission data of the second priority data is transmitted.

Specifically, for one possible implementation of the first mode: determining the PUSCHs for determining the PHR according to the time for transmitting data of each PUSCH, comprising: determining a PUSCH on which data is transmitted first in time among PUSCHs on which first priority data is transmitted and PUSCHs on which second priority data is transmitted as PUSCHs for determining PHR.

Specifically, the PUSCH for transmitting data first in time is determined as the PUSCH for determining the PHR, and the PHR (Power Headroom Report) is determined according to the Power control parameter of the PUSCH for transmitting data first in time, and the determined PHR is transmitted, for example, as shown in fig. 12, PUSCH-2 is earlier in time than PUSCH-1, so PUSCH-2 may be determined as the PUSCH for determining the PHR, and the PHR is determined according to the Power control parameter of PUSCH-2, and the determined PHR is transmitted.

In the foregoing implementation manner, only the order of the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data in data transmission time needs to be considered to determine the PUSCH for determining the PHR, in the following embodiments, whether the two PUSCHs meet the delay requirement needs to be considered first, and then the PUSCH for determining the PHR is determined, which is specifically shown as follows:

according to another possible implementation manner of the first manner, determining the PUSCH for determining the PHR according to the time for transmitting data of each PUSCH includes: if any PUSCH in the PUSCHs for transmitting the first priority data and the PUSCHs for transmitting the second priority data meets the delay requirement, determining the PUSCHs meeting the delay requirement as the PUSCHs for determining the PHR; or if the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data both meet the delay requirement, determining the PUSCH for transmitting the first transmission data in time from the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data as the PUSCH for determining the PHR.

In the embodiment of the application, whether each PUSCH of a PUSCH for transmitting first priority data and a PUSCH for transmitting second priority data meets a delay requirement or not may be determined first, if both the PUSCH of the first priority data and the PUSCH of the second priority data are met, the PUSCH of the first transmission data in time is determined as the PUSCH for determining the PHR, the PHR is determined according to a power control parameter of the PUSCH of the first transmission data in time, and the determined PHR is sent; if only one of the PUSCHs for transmitting the first priority data and the PUSCHs for transmitting the second priority data meets the delay requirement, determining the PUSCHs meeting the delay requirement as the PUSCHs for determining the PHR, determining the PHR according to the power control parameters of the PUSCHs meeting the delay requirement, and sending the determined PHR; if the time delay requirements are not met, determining the PHR according to the default power control parameters, and sending the determined PHR.

The manner for determining whether each PUSCH in the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data meets the delay requirement is detailed in the above embodiments, and details are not repeated here.

And the second mode is that the PUSCH used for determining the PHR is determined according to the scheduled time of each PUSCH.

In the second mode, according to the scheduled time of each PUSCH in the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data, the PUSCH for determining the PHR is determined, the PHR is determined based on the determined power control parameter of the PUSCH, and the determined PHR is further transmitted.

Specifically, determining the PUSCH for determining the PHR according to the scheduled time of each PUSCH includes: and determining the PUSCH of the first scheduled transmission data in time from the PUSCH transmitting the data of the first priority and the PUSCH transmitting the data of the second priority as the PUSCH for determining the PHR. I.e. the PUSCH of the transmission data scheduled earliest in time is determined as the PUSCH for determining the PHR.

Further, a PHR is determined according to a control parameter of a PUSCH for transmitting data that is scheduled earliest in time, and the determined PHR is transmitted, as shown in fig. 13, if the PUSCH that is scheduled earliest in time is PUSCH-1, the PHR is determined according to the control parameter of PUSCH-1, and the determined PHR is transmitted.

Further, in addition to determining the PUSCH for determining the PHR according to the time at which the PUSCH transmits data and the scheduled time of the PUSCH, the PUSCH for determining the PHR may be determined according to the type of the PUSCH (the type of each of the PUSCH transmitting the first priority data and the PUSCH transmitting the second priority data), the PHR is determined according to the determined power control parameter of the PUSCH, and the determined PHR is further transmitted.

In one possible example, the category of PUSCH includes: DCI for scheduled PUSCH and configured PUSCH, and therefore, in this case, the PUSCH for determining PHR is determined in the third embodiment.

And determining the PUSCH transmitting the first priority data or the PUSCH transmitting the second priority data as the PUSCH for determining the PHR if each PUSCH comprises the DCI scheduled PUSCH and the configured PUSCH.

Specifically, if the PUSCH for transmitting the first priority data and the PUSCH for transmitting the second priority data include the DCI scheduled PUSCH and the configured PUSCH, the DCI scheduled PUSCH may be selected as the PUSCH for determining the PHR, the PHR is determined according to the determined power control parameter of the PUSCH, and the determined PHR is sent; of course, the configured PUSCH may also be selected as the PUSCH for determining the PHR, and the PHR is determined according to the determined power control parameter of the PUSCH, and then the determined PHR is transmitted.

Further, in the third mode, the PUSCH for determining the PHR is determined according to the type of the PUSCH, and another possible implementation may also determine the PUSCH for determining the PHR according to a relationship between the PHR driven by a Timer (Timer) and each PUSCH, which is specifically as follows:

and determining the PUSCHs for determining the PHR according to the relation between the PHR driven by the timer and each PUSCH.

The relationship between the timer-driven PHR and each PSCH may include: the timer-driven PHR is a PHR for a PUSCH transmitting first priority data, and the timer-driven PHR is a PHR for a PUSCH transmitting second priority data. In the embodiment of the present application, the PHR for the PUSCH transmitting the first priority data may be referred to as a first priority PHR, and the PHR for the PUSCH transmitting the second priority data may be referred to as a second priority PHR. That is, the first priority PHR and the second priority PHR are driven by different timers.

Therefore, on the basis of the above embodiments, determining the PUSCH for determining the PHR according to the relationship between the PHR driven by the timer and each PUSCH includes: if the PHR driven by the timer corresponds to the PUSCH for transmitting the first priority data, determining the PUSCH for transmitting the first priority data as the PUSCH for determining the PHR; and if the PHR driven by the timer corresponds to the PUSCH for transmitting the second priority data, determining the PUSCH for transmitting the second priority data as the PUSCH for determining the PHR.

Further, after determining the PUSCH for determining the PHR, determining the PHR according to the determined power control parameter of the PUSCH, and then transmitting the determined PHR.

For a possible example of the fourth mode, as shown in fig. 8, the DCI in the slot n-4 schedules the PUSCH-1 to transmit in the slot n (or in the time unit n), and the DCI in the slot n-2 schedules the PUSCH-2 to transmit in the slot n (or in the time unit n), that is, when the PUSCH for transmitting the first priority data overlaps with the PUSCH for transmitting the second priority data and the PUSCH for transmitting the first priority data replaces the PUSCH for transmitting the second priority data, if the PHR timer drives the first priority PHR on the time unit n, the PUSCH for transmitting the first priority data is determined to be the PUSCH for determining the PHR, and the PHR is determined according to the power control parameter of the PUSCH for transmitting the first priority data, and then the determined PHR is transmitted;

for another possible example of the fourth mode, if the PUSCH for transmitting the first priority data overlaps with the PUSCH for transmitting the second priority data in time unit n + k, and the PUSCH for transmitting the first priority data replaces the PUSCH for transmitting the second priority data, if the PHR timer drives the second priority PHR in time unit n + k, the PUSCH for transmitting the second priority data is determined to be the PUSCH for determining the PHR, the PHR is determined according to the power control parameter of the PUSCH for transmitting the second priority data, and the determined PHR is further transmitted.
