Description

Power distribution method, device and system

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a power allocation method, apparatus, and system.

Background

Currently, in order to be able to support a larger transmission bandwidth, a terminal device (UE) often adopts carrier aggregation (Carrier Aggregation, CA) technology to aggregate 2 or more carrier units (Component Carrier, CC) together for communication transmission. Wherein, a UE configured with CA may be connected to 1 Primary Cell (PCell) and a plurality of Secondary cells (scells), the PCell is mainly responsible for RRC communication with the UE, a corresponding carrier element is called a Primary carrier (Primary Component Carrier, PCC), and the SCell is mainly used for providing additional radio resources, and a corresponding carrier element is called a Secondary carrier (Secondary Component Carrier, SCC).

Based on this, power allocation to a Primary Cell (PCell) and a Secondary Cell (SCell) of the UE needs to be considered. In the existing power allocation method, as the PCell has higher priority in power allocation, the situation that the Scell has no power available and the communication performance is reduced (drop) often occurs, so that the power allocation effect is not ideal enough. Therefore, there is a need to find a better power allocation scheme.

Disclosure of Invention

The application provides a power distribution method, a device and a system, which are used for providing a better power distribution scheme between a main cell and a secondary cell.

The power allocation method provided in the first aspect may be performed by a terminal device, where the terminal device may be abstracted as a computer system. The terminal device may be a complete machine, or may be a part of devices in the complete machine, for example: a system chip or a processing chip. The system-on-chip may also include a system-on-chip (SOC), or SOC chip, among others.

The following describes an example in which an execution subject is a terminal device.

The embodiment of the application provides a power configuration method, which comprises the following steps:

receiving first information sent by the network equipment, wherein the first information is used for indicating the power proportion of a main carrier and/or the power proportion of an auxiliary carrier corresponding to the terminal equipment; and carrying out power distribution for each corresponding carrier according to the first information.

By the method, the terminal equipment receives the power proportion from the network equipment, so that power distribution can be reasonably carried out for each carrier according to the power proportion configured by the network equipment, and a better power distribution scheme between the main cell and the auxiliary cell is provided.

In addition, based on the method, when the terminal equipment performs power distribution according to the power proportion issued by the network equipment, the condition that the communication performance is reduced due to the fact that the Scell is not available with power can be effectively avoided.

In one possible design, the first information is indicated by the network device through radio resource control, RRC, signaling; or the second information is indicated by the network device through downlink control information DCI; or the second information is indicated by the network device through a medium access control layer control unit MAC CE.

By means of the method, various modes for sending the first information by the network equipment are provided, and adaptability is higher.

In one possible design, the method includes receiving RRC signaling sent by the network device, where the RRC signaling includes at least one power ratio; receiving DCI sent by the network equipment, wherein the DCI is used for determining a first power proportion from the at least one power proportion; and carrying out power distribution for each corresponding carrier according to the first power proportion.

Through the method, the embodiment of the application provides a method for informing the terminal equipment of the power proportion for carrying out power distribution by the network equipment. For example, the network device may first notify the terminal device of a plurality of power ratios through RRC signaling, and assume that the power ratios notified to the terminal device by RRC signaling include power ratios 1 to 3. Then, the network device indicates which power ratio of the specific power ratio 1 to the specific power ratio 3 of the terminal device to perform power distribution through the DCI, that is, determines the first power ratio, for example, the DCI indicates the specific power ratio 1 to the specific power ratio 3 of the terminal device to perform power distribution.

In one possible design, the method includes receiving RRC signaling sent by the network device, where the RRC signaling includes at least one power ratio; receiving an MAC CE sent by the network equipment, wherein the MAC CE is used for determining a first power proportion from the at least one power proportion; and carrying out power distribution for each corresponding carrier according to the first power proportion.

Through the method, another method for informing the terminal equipment of the power proportion for power distribution by the network equipment is provided. For example, the network device may first notify the terminal device of a plurality of power ratios through RRC signaling, and assume that the power ratios notified to the terminal device by RRC signaling include power ratios 1 to 3. Then, the network device indicates which power ratio of the specific power ratio 1 to the specific power ratio 3 of the terminal device to perform power distribution through the MAC CE, that is, determines the first power ratio, for example, the MAC CE indicates the specific power ratio 1 to the specific power ratio 3 of the terminal device to perform power distribution.

In one possible design, the second information sent by the network device is received before the power allocation is performed for each corresponding carrier according to the first information, where the second information is used to indicate to activate the first information.

By the above method, in the embodiment of the present application, a condition that the terminal device performs power allocation using the first information is provided, for example, the condition that the terminal device performs power allocation using the first information may be that the terminal device receives the second information sent by the network device, where the second information is used to indicate to activate the first information.

In one possible design, before the power allocation is performed for each corresponding carrier according to the first information, it is determined that the current communication scenario is a carrier aggregation CA scenario.

By the above method, another condition that the terminal device adopts the first information to perform power allocation is provided in the embodiment of the present application, for example, before the terminal device adopts the first information to perform power allocation, it needs to determine that the current communication scenario is a CA scenario.

In one possible design, the first information includes a plurality of power ratios; each power ratio of the plurality of power ratios corresponds to an application scenario; the application scene comprises a scene of a main carrier and an auxiliary carrier on a band and a scene of the main carrier and the auxiliary carrier not on the band.

By the method, the content of the first information is described by way of example, for example, the first information may include only one power ratio, or the first information may include a plurality of power ratios, where when the first information includes a plurality of power ratios, each power ratio corresponds to an application scenario. It may be appreciated that when the first information includes a plurality of power ratios, the content of the first information may include a correspondence relationship between the power ratios and the application scenario.

In one possible design, a first power ratio for power allocation is determined from the plurality of power ratios according to a current application scenario; and carrying out power distribution for each corresponding carrier according to the first power proportion.

Through the above method, the embodiment of the application provides a method for determining a power ratio for performing power allocation, for example, a terminal device may select, according to a current application scenario, a power ratio corresponding to the current application scenario for performing power allocation.

In one possible design, the first information includes N bits, where M1 bits of the N bits are used to indicate a corresponding power ratio in a first application scenario; the M2 bits in the N bits are used for indicating the corresponding power proportion in the second application scene; wherein M1 and M2 are different bits, the value of N is greater than or equal to 2M, and M is a positive integer.

By the above method, the embodiment of the present application describes the content of the first information by way of example again, for example, when it is assumed that the first information includes N bits, M1 bits of the N bits may be used to represent a power ratio in one application scenario, M2 bits of the N bits may be used to represent a power ratio in another application scenario, and so on. It will be appreciated that this corresponds to dividing the N bits in the first information into a plurality of parts, each indicating a power ratio.

In one possible design, before the first information sent by the network device is received, third information is sent to the network device, where the third information is used to indicate a maximum available power value of the terminal device.

By the method, the terminal equipment can report the corresponding maximum available power value to the network equipment, so that the network equipment can better and more reasonably distribute the power proportion based on the reported maximum available power value of the terminal equipment.

The power allocation method provided by the second aspect may be performed by a network device, wherein the network device may be abstracted as a computer system. The network device may be a complete machine, or may be a part of devices in the complete machine, for example: a system chip or a processing chip. The system-on-chip may also include a system-on-chip (SOC), or SOC chip, among others.

The following describes an example in which the execution body is a network device.

The embodiment of the application provides a power distribution method, which comprises the following steps:

determining first information, wherein the first information is used for indicating the power proportion of a main carrier and/or the power proportion of an auxiliary carrier corresponding to the terminal equipment; and sending the first information to the terminal equipment.

In one possible design, the second information is indicated to the terminal device by radio resource control, RRC, signaling; or indicating the second information to the terminal equipment through downlink control information DCI; or the second information is indicated to the terminal equipment through a media access control layer control unit (MAC CE).

In one possible design, RRC signaling is sent to the terminal device, where the RRC signaling includes at least one power ratio; and the DCI is used for determining a first power proportion for carrying out power distribution from the at least one power proportion.

In one possible design, RRC signaling is sent to the terminal device, where the RRC signaling includes at least one power ratio; and the MAC CE is used for determining a first power proportion for carrying out power distribution from the at least one power proportion.

In one possible design, second information may also be sent to the terminal device, where the second information is used to indicate activation of the first information.

In one possible design, before the first information is sent to the terminal device, it may also be determined that the current communication scenario is a carrier aggregation CA scenario.

By the method, when the network equipment determines the power proportion, factors such as the number of RBs corresponding to the carrier, the maximum available power value of the terminal equipment, the priority of the carrier and the like can be combined, so that the power proportion can be better and more reasonably distributed.

In one possible design, the higher priority carriers may occupy a higher proportion of power than the lower priority carriers, or the higher priority carriers may be configured to have a higher proportion of power than the carriers need to allocate resources in accordance with the RB.

By the method, the embodiment of the application provides a manner of determining the first information based on the priority of the carrier, for example, the network device may adjust the power proportion occupied by the carrier with high priority according to the priority on the basis of RB resource allocation corresponding to the carrier.

In the following, some terms in the embodiments of the present application are explained for easy understanding by those skilled in the art.

1) The DCI in the embodiments of the present application may indicate cell-level information, such as downlink control information that indicates that a terminal device uses a system message radio network temporary identifier (system information, radio network temporary identifier, RNTI, SI-RNTI), a paging RNTI (paging RNTI, P-RNTI), or a random access RNTI (RA-RNTI), or may indicate terminal-level information, such as downlink control information that indicates that a terminal device uses a cell RNTI (cell RNTI, C-RNTI), a configuration scheduling RNTI (configured scheduling RNTI, CS-RNTI), a modulation coding scheme C-RNTI (modulation and coding scheme C-RNTI, MCS-C-RNTI), or a semi-persistent CSI RNTI (semi-persistent CSI RNTI, SP-CSI-RNTI), or downlink control information that indicates a group common level, such as a slot format (slot format indication, SFI-RNTI), an interrupt (interrupt, INT-RNTI), a TPC transmission power control (Transmit Power Control-PUSCH-RNTI, TPC-PUSCH-RNTI), a transmission power control (Transmit Power Control-PUSCH-RNTI), or a TPC-PUCCH-36-SRS.

In this embodiment of the present application, the DCI may carry first information in the embodiment of the present application, where the first information is used to indicate a power ratio of a primary carrier and/or an auxiliary carrier corresponding to a terminal device; or, the DCI also has a power proportion of a main carrier and/or an auxiliary carrier corresponding to the indication terminal equipment; still alternatively, the DCI may further include a power ratio indicating a power allocation among a plurality of power ratios included in the first information.

2) The radio resource control (Radio Resource Control, RRC) in the embodiments of the present application is used to process the third layer information of the control plane between UE enodebs.

In this embodiment of the present application, the RRC signaling may carry first information, where the first information is used to indicate a power ratio of a primary carrier and/or an auxiliary carrier corresponding to a terminal device; or the RRC signaling also has the power proportion of the main carrier and/or the auxiliary carrier corresponding to the indication terminal equipment, etc.

3) The power ratio in the embodiment of the present application may be understood as the ratio of the carrier in the maximum available power of the terminal device.

The power ratio in the embodiment of the present application may be in a percentage form or a ratio form, which is not limited herein.

For example, the power proportion of the primary carrier corresponding to the terminal device may be represented as 60%, and the power proportion of the secondary carrier corresponding to the terminal device may be represented as 40%; or, the power ratio may also be expressed as that the power ratio of the secondary carrier corresponding to the terminal device to the primary carrier corresponding to the terminal device is 5:2.

By introducing the communication system in the embodiment of the present application, a specific description is given below for a process of power allocation.

As shown in fig. 3, an embodiment of the present application provides a power allocation method, which includes:

step 300: the network device determines first information, where the first information is used to indicate a power ratio of a primary carrier and/or a power ratio of a secondary carrier corresponding to the terminal device.

Optionally, the network device may determine the first information in combination with a plurality of factors, where the factors for determining the first information include, but are not limited to, three of the following:

factor 1: and the number of RBs of the main carrier and/or the auxiliary carrier corresponding to the terminal equipment.

In an optional manner of this embodiment of the present application, the network device may determine the first information according to a ratio of the RB number of the primary carrier to the RB number of the secondary carrier.

For example, assuming that the number of RBs corresponding to the primary carrier is 100, the number of RBs corresponding to the secondary carrier is 50, and the ratio of the number of RBs of the primary carrier to the number of RBs of the secondary carrier is 2:1, the first information determined by the network device may indicate that the power ratio of the primary carrier to the secondary carrier corresponding to the terminal device is 2:1.

Factor 2: maximum available power value (P of terminal equipment _cmax,CA )。

In the embodiment of the application, when the network device determines the first information, the maximum available power value of the terminal device is combined, so that the power size of the current main carrier and the auxiliary carrier which can be used for distribution can be better known, and the power proportion can be better determined by combining other factors.

The maximum available power of the terminal device in the embodiment of the present application may be indicated by the third information sent by the terminal device before executing the embodiment S300 of the present application.

In particular, the terminal device may also send third information to the network device, the third information being used to indicate the maximum available power value of the terminal device.

Optionally, the third information may be carried in a power allocation request sent by the terminal device to the network device, so that after the network device receives the power allocation request sent by the terminal device, the maximum available power value of the terminal device may be determined according to the third information carried in the power allocation request.

Alternatively, when the third information is not carried in the power allocation request, the terminal device may transmit the third information after transmitting the power allocation request to the network device, or the terminal device may transmit the third information before transmitting the power allocation request to the network device.

The third information may be reported through RRC signaling or along with PHR, or may be reported in the MAC-CE according to requirements such as reporting period/time, which is not limited herein.

Factor 3: priority of the primary carrier and/or the secondary carrier corresponding to the terminal device.

In an alternative manner of the embodiment of the present application, the network device may set a higher power ratio for a carrier with a high priority, and set a relatively lower power ratio for a carrier with a low priority. In this embodiment, the high priority carrier may be a primary carrier or a secondary carrier, which is not limited herein.

For example, when the network device determines the first information in combination with the factors 1 and 3, it is assumed that the number of RBs corresponding to the primary carrier is 50, the number of RBs corresponding to the secondary carrier is 50, and the priority of the primary carrier is higher than the priority of the secondary carrier, where, although the ratio of the number of RBs of the primary carrier to the number of RBs of the secondary carrier is 1:1, the network device may set a higher power ratio for the primary carrier when determining the power ratio of the carriers, for example, the power ratio of the primary carrier to the secondary carrier set by the network device is 2:1. Therefore, when the terminal equipment performs power distribution according to the power proportion, the main carrier can be distributed with more power.

Step 301: the network device sends the first information to the terminal device.

In this embodiment, the network device sends the first information to the terminal device in multiple manners, which is not limited to the following specific manners:

transmission scheme 1: the first information is indicated by the network device through RRC signaling.

For example, the network device may carry the first information in RRC signaling sent to the terminal device; or, the network device may send RRC signaling to the terminal device, where the RRC signaling is used to indicate the power ratio of the primary carrier and/or the secondary carrier corresponding to the terminal device, i.e. the first information.

Transmission method 2: the first information is indicated by the network device through DCI.

For example, the network device may carry the first information in DCI sent to the terminal device; or, the network device may send DCI to the terminal device, where the DCI is used to indicate a power ratio of a primary carrier and/or a secondary carrier corresponding to the terminal device, that is, the first information.

Transmission method 3: the first information is indicated by the network device through a MAC CE.

For example, the network device may carry the first information in a MAC CE sent to the terminal device; or, the network device may send the MAC CE to the terminal device, where the MAC CE is used to indicate the power proportion, i.e. the first information, of the primary carrier and/or the secondary carrier corresponding to the terminal device.

Transmission method 4: the first information is indicated by the network device in combination with DCI through RRC signaling.

For example, the network device may carry at least one power ratio in RRC signaling sent to the terminal device, and then the network device may also send DCI to the terminal device, the DCI being used to determine the first power ratio from the at least one power ratio. The first power ratio is a power ratio applied when the terminal equipment allocates power to each corresponding carrier.

Transmission method 5: the first information is indicated by the network device in combination with MAC CE through RRC signaling.

For example, the network device may carry at least one power ratio in RRC signaling sent to the terminal device, and then the network device may also send a MAC CE to the terminal device, the MAC CE being configured to determine a first power ratio from the at least one power ratio. The first power ratio is a power ratio applied when the terminal equipment allocates power to each corresponding carrier.

Further, in the embodiment of the present application, before the network device sends the first information to the terminal device, the network device may determine fourth information received from the terminal device sent, where the fourth information is used to indicate the capability of the terminal device to support power allocation according to the power proportion indicated by the first information.

Based on this, the network device may determine from the fourth information that the terminal device has the capability to support power allocation in accordance with the power ratio indicated by the first information. Therefore, the network device can send the first information to the terminal device, so that the system overhead generated by sending the first information to the terminal device still when the terminal device does not have the capability of supporting power distribution according to the power proportion indicated by the first information is effectively avoided, and the power consumption is effectively reduced.

In this embodiment of the present application, the terminal device may send the fourth information at a time before receiving the first information from the network device.

Step 302: the terminal device receives first information from the network device.

Step 303: and the terminal equipment allocates power for each corresponding carrier according to the first information.

After receiving the first information, the terminal device may determine a power ratio of the carrier configuration according to the first information.

For example, the terminal device may convert the power of different CCs to p _cmax，CA * ratio (i) or p _CMAX，f，c * The ratio (i) is configured in a manner that the ratio (i) is a power ratio on the CC (i).

Wherein P is _CMAX，f，c The range of values of (2) can be referred to as the following equation 1:

P _{CMAX_L，f，c} ≤P _CMAX，f，c ≤P _{CMAX_H，f，c} Equation 1

In an alternative manner, P in equation 1 _{CMAX_L，f，c} Can be determined by the following equation 2P in the formula 1 _{CMAX_H，f，c} Can be determined by the following equation 3.

P _{CMAX_L，f，c} ＝MIN{P _EMAX，c -ΔT _C，c ，(P _PowerClass -ΔP _PowerClass )

-MAX(MAX(MPR _c +ΔMPR _c ，A-MPR _c )+ΔT _IB，c +ΔT _C，c +ΔT _RXSRS ，P

-MPRc)，P _cmax，CA +10log ₁₀ p _{ratio，f，c} Equation 2

P _{CMAX_H，f，c} ＝MIN{P _EMAX，c ，P _PowerClass -ΔP _PowerClass ，P _cmax，CA +10log ₁₀ p _{ratio，f，c} Equation 3

In another alternative mode of the embodiment of the present application, P in formula 1 _{CMAX_L，f，c} Can be determined by the following equation 4, P in equation 1 _{CMAX_H，f，c} Can be determined by the following equation 5.

P _{CMAX_L，f，c} ＝MIN{P _EMAX，c -ΔT _C，c ，(P _PowerClass -ΔP _PowerClass )-MAX(MAX(MPR _c

+ΔMPR _c ，A-MPR _c )+ΔT _IB，c +ΔT _C，c +ΔT _RXSRS ，P-MPR _c )

+10log ₁₀ p _{ratio，f，c} Equation 4

P _{CMAX_H，f，c} ＝MIN{P _EMAX，c ，P _PowerClass -ΔP _PowerClass }+10log ₁₀ p _{ratio，f，c} Equation 5

Wherein p in the above formula _{ratio，f，c} Power proportion information which indicates that the network equipment is configured for different carriers according to the primary and secondary carrier resource scheduling information for different terminal equipment; p (P) _cmax，CA For the total available transmit power of the terminal device, wherein p _cmax，CA Is P _cmax，CA A corresponding linear value; p (P) _EMAX，c Representing the maximum allowed transmitting power of the Cell, and configuring parameters of a network side per Cell; p (P) _PowerClass Indicating the maximum transmitting power of the UE; ΔP _PowerClass The method comprises the steps that parameters of maximum output power of the UE are regulated according to the uplink duty cycle (duty cycle) capability of the working period reported by the UE and the uplink duty cycle of network scheduling; delta T _IB，c Representing the extra power loss introduced when the UE supports the combination of frequency bands; delta T _C，c Representing the extra power loss introduced by the edge insertion loss of the transition band of the frequency band filter; Δmpr _c Indicating additional power backoff; delta T _RXSRS Indicating additional power backoff introduced when the UE supports SRS antenna selection; P-MPR _c Indicating that the power backoff introduced by human radiation safety is satisfied.

In an optional manner, in this embodiment of the present application, if the terminal device does not receive the first information sent by the network device within the preset duration, the terminal device may perform power allocation for each corresponding carrier according to the existing manner, or the terminal device may use a default power ratio to perform power allocation for each corresponding carrier.

In another optional manner of this embodiment of the present application, if the terminal device receives the indication that the first information sent by the network device is invalid before performing power allocation for each corresponding carrier according to the information in this embodiment of the present application, the terminal device may perform power allocation for each corresponding carrier according to an existing manner, or the terminal device may use a default power ratio to perform power configuration for each corresponding carrier.

The default power ratio in the embodiment of the present application may be understood as a power ratio preset in the embodiment of the present application. The default power ratio may be stored locally at the terminal device or in a third party storage platform accessible to the terminal device, and embodiments of the present application are not limited in this regard.

In order to better describe the communication method provided by the application, based on the content shown in fig. 3, the following two scenarios are combined for further detailed description.

It should be noted that, some steps in the scenario referred to below may be optional, and the sequence of steps does not represent the actual execution sequence, so the application is not limited to being executed entirely according to the steps and sequences described below.

And when the first scene is that the terminal equipment determines that the received first information sent by the network equipment is in an activated state, carrying out power distribution for the corresponding carrier wave according to the first information.

Specifically, after receiving the first information sent by the network device, the terminal device performs power allocation for the corresponding carrier according to the first information when receiving the second information sent by the network device. Wherein the second information is used to indicate activation of the first information.

Referring to fig. 4, an embodiment of the present application provides a power allocation method based on the first scenario, where a specific flow includes:

step 400: the network device determines first information, where the first information is used to indicate a power ratio of a primary carrier and/or a secondary carrier corresponding to the terminal device.

Step 401: the network device sends the first information to the terminal device.

Step 402: the terminal device receives first information sent by the network device.

Step 403: the network device sends second information to the terminal device, wherein the second information is used for indicating to activate the first information.

In an optional manner of this embodiment of the present application, the condition for triggering the network device to send the second information to the terminal device may be that the network device sends the second information to the terminal device after receiving the power allocation request from the terminal device.

Further, in the embodiment of the present application, the second information may specifically indicate a time when the first information takes effect, or a condition of taking effect, which is not limited herein.

Step 404: the terminal device receives the second information sent from the network device.

In one case, the second indication information is an activation indication, and the terminal device directly triggers activation of the first information after receiving the second information.

In another case, the second information may include a time or a condition for activating the first information, and when the terminal device reaches the activation time, or when the terminal device satisfies the activation condition, activation of the first information is triggered.

For example, the second information indicates that activation of the first information is triggered at time a, so that after the terminal device receives the second information, activation of the first information is triggered when the terminal device determines that the current time is time a according to the content indicated by the second information.

For another example, the information included in the second information is that activation of the first information is triggered in the CA scene, so that after the terminal device receives the second information, according to the content indicated by the second information, when the terminal device determines that the terminal device is currently in the CA scene, activation of the first information is triggered.

In yet another case, the second information is used to indicate that the first power ratio included in the first information is in effect.

When the first information includes a plurality of power ratios, for example, the first information includes a power ratio 1 to a power ratio 3, and the second information may be used to indicate that the power ratio 1 included in the first information is effective, the terminal device performs power allocation for the corresponding carrier according to the power ratio 1 of the first information. The first information may be indicated by the network device through RRC signaling, and the second information may be indicated by the network device through DCI.

Step 405: and the terminal equipment allocates power for each corresponding carrier according to the first information.

And when the terminal equipment determines that the received first information sent by the network equipment is in the deactivation state, stopping using the first information to perform power distribution for the corresponding carrier.

Specifically, after receiving the first information sent by the network device, the terminal device stops using the first information to perform power allocation for the corresponding carrier when receiving the fifth information sent by the network device. Wherein the fifth information is used to indicate that the first information is deactivated.

Referring to fig. 5, an embodiment of the present application provides a power allocation method based on the second scenario, where a specific flow includes:

step 500: the network device determines first information, where the first information is used to indicate a power ratio of a primary carrier and/or a secondary carrier corresponding to the terminal device.

Step 501: the network device sends the first information to the terminal device.

Step 502: the terminal device receives first information from the network device.

Step 503: the network device sends fifth information to the terminal device, wherein the fifth information is used for indicating to deactivate the first information.

In an optional manner, the condition for triggering the network device to send the fifth information to the terminal device may be that the network device receives a PCell priority request sent by the terminal device. Based on this, the network device may send fifth information to the terminal device.

Further, in the embodiment of the present application, the fifth information may specifically indicate the time when the first information fails, or the failure condition, etc., which is not limited herein.

Step 504: the terminal device receives the fifth information sent from the network device.

In one case, the fifth indication information is a deactivation indication, and the terminal device directly triggers deactivation of the first information after receiving the fifth information.

In another case, the fifth information may include a time or a condition for deactivating the first information, and when the terminal device reaches the deactivation time, or when the terminal device satisfies the deactivation condition, deactivation of the first information is triggered.

For example, the information included in the fifth information is that deactivation of the first information is triggered at the time B, so that after the terminal device receives the fifth information, according to at least the content of the fifth information, when the terminal device determines that the current time is the time B, deactivation of the first information is triggered.

For another example, the information included in the fifth information is to trigger deactivation of the first information in the PCell-prioritized scenario, so that after the terminal device receives the fifth information, according to the content indicated by the fifth information, when the terminal device determines that the terminal device is currently in the PCell-prioritized scenario, deactivation of the second information is triggered.

In yet another case, the fifth information is used to indicate that the first power ratio included in the first information is invalid.

When the first information includes a plurality of power ratios, for example, the first information includes a power ratio of 1 to a power ratio of 3, and the fifth information may be used to indicate that the power ratio of 1 to 2 included in the first information is invalid, the terminal device performs power allocation for the corresponding carrier according to the power ratio of 3 included in the first information.

Step 505: and the terminal equipment determines that the partial or all power proportion included in the first information is not adopted according to the fifth information, and performs power distribution for each corresponding carrier.

In the second scenario, when the first information is in the deactivated state, the terminal device may perform power allocation according to an existing manner, or the terminal device may perform power configuration by using a default power allocation ratio.

For example, as shown in fig. 6, when only PCell resources are scheduled, the power ratio allocated by the network device may be 100% for PCell and 0% for SCell.

Further, in the embodiment of the present application, the content indicated by the first information may have various situations, which is not specifically limited to the following:

Case 1: the first information includes a power ratio in an application scenario.

Specifically, in this case 1, only a power ratio corresponding to one application scenario is included in the first information.

The division manner of the application scenario in the embodiment of the present application may be determined based on the carrier allocation situation of the current terminal device, for example, the application scenario 1 is that the carrier allocation situation of the terminal device is a primary carrier PCC1, and two secondary carriers SCC1 and SCC2, and the application scenario 2 is that the carrier allocation situation of the terminal device is a primary carrier PCC1, and a secondary carrier SCC1; the application scenario may also be determined based on whether the primary carrier and the secondary carrier corresponding to the terminal device are on a single band, for example, application scenario 1 is a scenario in which the primary carrier and the secondary carrier of the terminal device are on a single band, and application scenario 2 is a scenario in which the primary carrier and the secondary carrier of the terminal device are not on a single band, which is not limited herein.

For example, it is assumed that the current carrier allocation situation of the terminal device is that the terminal device includes one primary carrier PCC1 and 1 secondary carrier SCC1. At this time, the power ratio determined by the network device for the application scenario may be as shown in table 1 below:

Carrier name	Power ratio
		Main carrier
	75％
		Auxiliary carrier	25％

Table 1 carrier to corresponding power allocation ratio case 1

Based on the content of table 1, the power allocation situation of the terminal device may be shown in fig. 7.

Case 2: the first information comprises index numbers of the application scene and the corresponding power proportion.

Specifically, in this case 2, the correspondence between the application scenarios and the power ratios may be stored in a third party platform, where an index number is allocated to each application scenario and the corresponding power ratio.

For example, the correspondence between the application scenario, the power ratio and the index number may be as shown in table 2:

table 2 application scenario, correspondence between power ratio and index number

Based on the above table 2, after the network device determines the power ratio of the carrier, according to the table 2, an index number corresponding to the power ratio of the carrier may be found, and then the index number is sent to the terminal device as the first information.

Thus, after receiving the first information, the terminal device may refer to the table 2 to determine the power ratio of the carrier corresponding to the index number according to the index number included in the first information.

Optionally, the first information may include one or more index numbers.

For example, when the index numbers included in the first information received by the terminal device are 2 and 3, the terminal device may determine the index number for performing power allocation according to the current application scenario of the terminal device; or, the terminal device may randomly select one index number from the index numbers 2 and 3 for application; or, the terminal device may determine a mean ratio by combining the power ratio corresponding to the index number 2 and the power ratio corresponding to the index number 3, and perform power allocation by combining the mean ratio.

By the mode, the size of the first information can be effectively reduced, the transmission power consumption is reduced, and the transmission resources are saved.

Case 3: the first information comprises power proportions corresponding to various application scenes.

Specifically, in this case 3, the first information includes power ratios corresponding to various application scenarios. Based on this, the first information may also be used to indicate a correspondence between the application scenario and the power ratio. In an optional manner, the first information includes N bits, where M1 bits in the N bits are used to indicate a corresponding power ratio in a first application scenario; m2 bits of the N bits are used for indicating the corresponding power proportion in the second application scene; wherein M1 and M2 are different bits, the N value is more than or equal to 2M, and M is a positive integer.

As an example, as shown in fig. 8, assume that the first information has a length of 120 bits, where the first 40 bits are used to indicate a power ratio corresponding to the first application scenario; the middle 40 bits are used for indicating the power proportion corresponding to the second application scene; the remaining 40 bits are used to indicate the power ratio corresponding to the third application scenario.

Further, in combination with the above cases 1 to 3, the embodiments of the present application further provide various expression forms of the power ratio corresponding to the application scenario, which are not limited to the following forms:

form (1): the power proportion corresponding to the application scene only comprises the power proportion of the main carrier corresponding to the terminal equipment.

For example, based on this case 1, the current first information is used to indicate the power ratio of the primary carrier corresponding to the terminal device.

It can be understood that, when the first information is used to indicate the power ratio of the primary carrier corresponding to the terminal device, the power ratio of the secondary carrier may be obtained according to the power ratio of the primary carrier.

For example, assuming that the terminal device corresponds to one PCell and one SCell, and the first information indicates that the power proportion of the primary carrier corresponding to the terminal device is 65%, it may be obtained that the power proportion of the secondary carrier corresponding to the terminal device should be 35%.

For another example, assuming that the power ratio of the primary carrier corresponding to the terminal device is 65% when the terminal device corresponds to one PCell and 2 scells, it may be obtained that the power ratio of the two secondary carriers corresponding to the terminal device should be 35%.

In an optional manner, the terminal device may distribute the power corresponding to the power ratio of 35% to two scells. For example, assuming that the allocable power of the terminal device is 100mW, the power allocated by the primary carrier is 65mW, and the power allocated by the 2 secondary carriers is 35mW according to the content indicated by the first information. At this time, the 35mW may be equally divided into two scells, each SCell allocating 17.5mW of power.

Form (2): the power proportion corresponding to the application scene only comprises the power proportion of the auxiliary carrier corresponding to the terminal equipment.

For example, based on the case 1, the current first information is used to indicate the power ratio of the secondary carrier corresponding to the terminal device.

It can be understood that, when the first information is used to indicate the power ratio of the secondary carrier corresponding to the terminal device, the power ratio of the primary carrier may be obtained according to the power ratio of the primary carrier.

For example, assuming that the terminal device corresponds to one PCell and one SCell, and the first information indicates that the power proportion of the secondary carrier corresponding to the terminal device is 30%, it may be obtained that the power proportion of the primary carrier corresponding to the terminal device should be 70%.

For another example, assuming that the terminal device corresponds to one PCell and 2 scells (e.g., SCell-1, SCell-2), the first information indicates that the power ratio of SCell-1 corresponding to the terminal device is 20% and the power ratio of SCell-2 is 10%, it may be obtained that the power ratio of the primary carrier corresponding to the terminal device should be 70%.

In an optional manner, the first information may further indicate a power ratio shared by each secondary carrier of the terminal device.

For example, the first information indicates that the power ratio shared by the secondary carriers of the terminal device is 20%, and the terminal device currently corresponds to one PCell and two scells (e.g., SCell-1, SCell-2). Therefore, the terminal device can determine that the power ratio of the SCell-1 is 20% and the power ratio of the SCell-2 is 20% according to the first information, and further can obtain that the power ratio of the primary carrier corresponding to the terminal device should be 60%.

Form (3): the power proportion corresponding to the application scene comprises the power proportion of the main carrier wave and the auxiliary carrier wave corresponding to the terminal equipment.

For example, based on the case 1, the current first information is used to indicate the power ratio of the primary carrier and the secondary carrier corresponding to the terminal device.

The first information indicates that the power ratio of the secondary carrier corresponding to the terminal device is 30% and the power ratio of the primary carrier corresponding to the terminal device is 70%, so that the terminal device can perform power allocation of the primary carrier and the secondary carrier according to the first information.

For another example, assuming that the terminal device corresponds to one PCell and 2 scells (for example, SCell-1 and SCell-2), the first information indicates that the power ratio of SCell-1 corresponding to the terminal device is 20%, the power ratio of SCell-2 is 10%, and the power ratio of PCell is 70%, and the terminal device may perform power allocation of the primary carrier and the secondary carrier according to the first information.

In an optional manner, the first information may further indicate a power ratio of the primary carrier of the terminal device and a power ratio shared by the secondary carriers.

For example, the first information indicates that the power ratio of the primary carrier of the terminal device is 60% and the power ratio shared by the respective secondary carriers is 20%. The terminal device currently corresponds to one PCell and two scells (e.g., SCell-1, SCell-2). Therefore, the terminal device may determine that the power ratio of the SCell-1 is 20%, the power ratio of the SCell-2 is also 20%, and the power ratio of the PCell should be 60% according to the first information.
