Description

Information transmission method, device and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, an information transmission device, and a storage medium.

Background

When the terminal equipment works under the frequency band combination, a plurality of carriers configured by the network share the total transmitting power capability of the terminal equipment. The total transmit power of the terminal device on multiple carriers will not exceed the maximum transmit power configurable by the terminal device, thus, when the transmit power on one carrier increases, meaning that the transmit power available to other carriers will decrease. When one carrier occupies all of the transmit power, no transmit power will be available on the other carriers. There is also a priority in the power used between carriers, i.e. the power requirement of the high priority carrier is met first, and then the power requirement of the low priority carrier is met further. When the transmission power of the low priority carrier cannot meet the link requirement, the carrier is dropped, and if the low priority carrier is the main carrier, the main carrier and the spoke carrier are dropped simultaneously. Under the existing mechanism, the terminal equipment reports the transmission power allowance of each carrier wave by taking the carrier wave as granularity, which leads to that the base station can only know the transmission power allowance of each carrier wave, when the total transmission power of the terminal equipment on a plurality of carrier waves reaches the maximum configurable power, the base station continues to schedule and improve the transmission power of the terminal, the terminal equipment can only meet the transmission power of the carrier wave with high priority by reducing the transmission power of the carrier wave with low priority, and finally the carrier wave with low priority is released due to the too low transmission power.

A network device may also refer broadly to a general term for all devices on the network side, for example, when a plurality of TRPs are used to transmit data to a terminal device, the plurality of TRPs are collectively referred to as a network device.

In the embodiment of the application, the terminal equipment is equipment with a wireless receiving and transmitting function, and can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.).

The embodiments of the present application are not limited to application scenarios. A terminal device may also sometimes be referred to as a terminal, user Equipment (UE), access terminal device, vehicle terminal, industrial control terminal, UE unit, UE station, mobile station, remote terminal device, mobile device, UE agent, UE apparatus, or the like. The terminal device may also be fixed or mobile.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

Based on the network architecture shown in fig. 1, the information transmission method provided in the embodiment of the present application will be described in detail below. In the introduction, the names of the information interacted between the network device and the terminal device are used as examples, and are not limited to the embodiments of the present application.

When the terminal device is operating in a combination of frequency bands such as carrier aggregation (Carrier Aggregation, CA), LTE NR dual connectivity (LTE NR dual connectivity, EN-DC), dual connectivity (Dual Connectivity, DC), etc., the total transmit power of the terminal device on multiple carriers will not exceed the terminal device's configurable maximum transmit power. Thus, when the transmit power on one carrier increases, it means that the transmit power available to the other carriers will decrease. When one carrier occupies all of the transmit power, no transmit power will be available on the other carriers.

For example, the terminal device needs to transmit on the primary carrier (primary carrier component, PCC) and the secondary carrier (sencondary carrier component, SCC) simultaneously, if the primary carrier occupies most of the power, the transmit power on the secondary carrier is too small to maintain the uplink, which would lead to a situation where the SCC link is disconnected, i.e. only the PCC is operating. For example, the network will typically configure RB resources and schedule modulation coding, MCS, according to the signal quality on the carrier. When the terminal equipment is in the center of the cell, and the signal quality of the PCC is better, the network allocates more RBs and schedules higher MCS at the same time, so that the UE transmits high power on the PCC. At this time, the SCC may use only the remaining power because of its lower priority than the PCC, and the transmission power on the PCC is too high to maintain the link and the SCC link fails. In contrast, if both the PCC and the SCC are able to maintain the link in communication, their overall throughput will be better than if the PCC alone is transmitting.

In addition to the above, the relative priorities among multiple carriers are affected by a number of factors, including the types of channels transmitted on the carriers (e.g., PUSCH and PUCCH are prioritized over SRS, etc.), the traffic content carried by the channels (e.g., PUSCH and PUCCH are prioritized with respect to whether control information or traffic information is carried thereon, etc.), the direct indication priority of the network (e.g., the network signals whether the carrier is high or low), etc. Thus, when the SCC has a higher priority, the terminal will divide most of the power to the SCC transmissions, which will cause the PCC to drop, so that the terminal will experience a problem of disconnection from the network, since the SCC will drop if the PCC drops.

Current NRs use power for higher priority carriers first, and then allocate the remaining power to lower priority carriers for use in a band combination. Thus, when the high priority carrier occupies most or even all of the power, the low priority carrier will break the connection. Further, in the combination of bands such as CA, the priority of PCC may be lower than SCC, so there is a problem that once PCC power fails to maintain a link, both PCC and SCC will be dropped.

In order to solve the above technical problem, the terminal device of the present application may report a total power margin or indication information to the network device, where the total power margin is a difference between a total configurable maximum transmission power of the terminal device on a plurality of carriers and a total actual transmission power of the terminal device on a plurality of carriers, where the indication information is used to indicate that the total actual transmission power is close to or reaches the configurable maximum transmission power of the terminal device, or the indication information may also be used to indicate that the total actual transmission power exceeds the configurable maximum transmission power of the terminal device, or the indication information may also be used to indicate that a difference between the total configurable maximum transmission power of the terminal device on the plurality of carriers and the total actual transmission power of the terminal device on the plurality of carriers is smaller than or equal to a threshold value, or the like. The network device may schedule the transmission power of the terminal device on the multiple carriers according to the total power margin or the indication information, for example, to increase the transmission power of the carrier with low priority and/or decrease the transmission power of the carrier with high priority, so as to avoid the technical problem that the low-priority carrier is released when the network device continues to schedule the transmission power of the terminal device to be increased (for example, continues to increase the transmission power of the carrier with high priority or continues to increase the transmission power of all carriers) when the high-priority carrier occupies most or all of the total configurable maximum transmission power, because the terminal device can only decrease the transmission power of the carrier with low priority to meet the transmission power of the carrier with high priority. The procedure of the information transmission method of the present application will be described in detail with reference to fig. 2.

Referring to fig. 2, a flow chart of an information transmission method provided in an embodiment of the present application is shown, and fig. 1 may be a network architecture example to which the information transmission method is applied. As shown in fig. 2, the method may include: S101-S103, wherein the execution sequence of each step is not limited. As shown in the figure, the information transmission method of the embodiment of the present application includes, but is not limited to, the following steps:

s101, a terminal device sends first information to a network device, wherein the first information comprises total power allowance or indication information, the total power allowance is determined based on total configurable maximum transmission power of the terminal device on a plurality of carriers and total actual transmission power of the terminal device on the plurality of carriers, and the indication information is used for indicating that the difference value between the total configurable maximum transmission power of the terminal device on the plurality of carriers and the total actual transmission power of the terminal device on the plurality of carriers is smaller than or equal to a threshold value.

In this embodiment of the present application, the scenario in which the terminal device transmits data on one or more carriers may be applicable, where the total actual transmission power of the terminal device on the one or more carriers is less than or equal to the total configurable maximum transmission power of the terminal device on the at least one carrier, where the total configurable maximum transmission power of the terminal device on the at least one carrier may also be referred to as the configurable maximum transmission power of the terminal device. The total actual transmission power of the terminal equipment on the plurality of carriers is equal to the sum of the actual transmission power of the terminal equipment on each carrier. In order to facilitate the network device to learn the relationship between the total actual transmission power and the total configurable maximum transmission power, and avoid the problem that when the total actual transmission power reaches or exceeds the total configurable maximum transmission power, the network device continues to schedule and increase the transmission power of the terminal device to cause the low priority carrier to be released, the terminal device may report the total power allowance or indication information to the network device through the first information, in some optional manners, the terminal device may further report the total configurable maximum transmission power, the maximum transmission power of each carrier and the power allowance of each carrier to the network device through the first information, so that the network device calculates the total power allowance, and in an exemplary manner, the network device may configure the terminal device to report one or more of the total configurable maximum transmission power, the total power allowance or the indication information. It should be noted that, in the embodiments of the present application, the first information may be reported through the auxiliary information, that is, one or more of the total configurable maximum transmission power, the total power margin, or the indication information may be reported through the auxiliary information.

In a first alternative embodiment, the terminal device may calculate a total power headroom phr_total according to a total configurable maximum transmission power pcmax_total of the terminal device on at least one carrier and a total actual transmission power of the terminal device on at least one carrier, where the total power headroom phr_total is a total transmission power headroom of the terminal device when transmitting on at least one carrier, which may be defined as a difference between the total configurable maximum transmission power pcmax_total and the total actual transmission power, taking fig. 3 as an example, where the actual transmission power of the carrier CC1 is pow_cc1 and the actual transmission power of the carrier CC2 is pow_cc2, the total actual transmission power is pow_cc1+pow_2, and the total power headroom=pmax_total- (pow_cc1+pow_cc2), and further, the terminal device sends first information to the network device, where the first information includes the total power headroom.

Further, to facilitate the network device to schedule the transmission power of each carrier, the first information may further include a total configurable maximum transmission power pcmax_total. Optionally, the network device may configure whether the terminal device reports the total configurable maximum transmission power pcmax_total.

In this embodiment, the first information may be sent through a Control Element (CE) of a medium access Control layer (Media Access Control, MAC), or may also be sent through uplink Control information (Uplink Control Information, UCI), or may also be sent through radio resource Control (radio resource Control, RRC), etc., where the terminal device may report the total power margin to the network device only when the network device configures multiple carriers for the terminal device, or may be adapted to report the total power margin to the network device when the network device configures a single carrier for the terminal device. The first information may be transmitted to the network device together with a power headroom per carrier and a maximum transmit power per carrier.

For example, when the network device configures the terminal device to operate in multicarrier transmission, the network device may send the first information through a MAC CE, where the MAC CE includes a Total power headroom phr_total, and optionally, the MAC CE may further include a Total configurable maximum transmission power pcmax_total, which is illustrated with reference to fig. 4a and 4b, where the Total power headroom phr_total is denoted by PH (Type X, total) and the Total configurable maximum transmission power pcmax_total is denoted by Pcmax, f, c Total in fig. 4a and 4 b.

As shown in fig. 4a, the MAC CE includes a Total power margin PH (Type X, total), which is indicated in italics in fig. 4a, and further, as shown in fig. 4a, the MAC CE may further include a power margin of each carrier and a maximum transmittable power of each carrier.

As shown in fig. 4b, the MAC CE includes a Total power margin PH (Type X, total) and a Total configurable maximum transmit power PCMAX, f, c Total, PH (Type X, total) and PCMAX, f, c Total are indicated in italics. Further, as shown in fig. 4b, the MAC CE may further include a power headroom of each carrier and a maximum transmittable power of each carrier.

For example, the terminal device may send the first information including the total power headroom to the network device if a reporting condition is satisfied, where the reporting condition may include one or more of the following:

1. the current time meets the reporting time indicated by a target period, wherein the target period is the reporting period of the total power allowance, namely the total power allowance is reported periodically;

2. the terminal device receives a trigger instruction sent by the network device, where the trigger instruction is used to trigger the terminal device to report the total power allowance to the network device, the trigger instruction may be RRC signaling, MAC CE, or physical layer DCI, etc., and it may be understood that the network device may also trigger the terminal device to stop reporting the total power allowance by triggering signaling, where the triggering terminal device may report the total power allowance may be called an activate report instruction, and the triggering terminal device may stop reporting the total power allowance may be called a deactivate report instruction;

3. The total actual transmit power is greater than a first threshold, which may be configured by the network device, or a predefined power value, such as a default value;

4. the total power margin is less than or equal to a second threshold, or the total actual transmission power is less than a second threshold of the total configurable maximum transmission power, where the second threshold may be 3dB, or 2dB, or 0, etc., and the second threshold may be configured by a network device, or a predefined power value, such as a default value;

5. the total power margin is equal to a first preset value, which may be 0dB, which may be configured by the network device, or a predefined power value, such as a default value;

6. the first timer is in an active state, where the active state of the first timer is used to indicate that the terminal device is allowed to report the total power headroom, and the first timer may be referred to as an allowed timer, i.e. the network device sets a time interval for allowing the terminal device to report the total power headroom and/or the total configurable maximum transmit power by activating the first timer. Further, the network device may also set a time interval for preventing the terminal device from reporting the total power margin and/or the total configurable maximum transmit power by activating a corresponding preventing timer, i.e. when the preventing timer is in an activated state, the terminal device is not allowed to report the total power margin and/or the total configurable maximum transmit power. It will be appreciated that the total power margin and/or the total configurable maximum transmit power allowed or blocked by the terminal device may also be controlled by a timer, for example, when the timer is in an active state, the total power margin and/or the total configurable maximum transmit power is allowed to be reported by the terminal device, and when the timer is in a deactivated state, the total power margin and/or the total configurable maximum transmit power is blocked from being reported by the terminal device.

It can be understood that each of the conditions 1 to 6 may be combined with each other to form a reporting condition, for example, if the terminal device is configured to semi-continuously report the first information, the network device configures the target period, and when the reporting time indicated by the target period needs to be met and a trigger instruction sent by the network device is received, that is, the reporting condition includes the condition 1 and the condition 2, and the terminal device reports the first information. For another example, the reporting condition includes the condition 3 and the condition 6, that is, when the first timer is required to be in an activated state and the total actual transmission power is greater than the first threshold, the terminal device sends the first information to the network device, and other combinations are not described one by one.

In some alternative embodiments, the above conditions 1-6 and combinations thereof may also be described as that the terminal device sending the first information to the network device may include:

sending first information to the network equipment according to the target period; and/or the number of the groups of groups,

when the terminal equipment receives a trigger instruction sent by the network equipment, first information is sent to the network equipment; and/or the number of the groups of groups,

when the total actual transmitting power is larger than a first threshold value, first information is sent to the network equipment; and/or the number of the groups of groups,

When the total power margin is smaller than or equal to a second threshold value, first information is sent to the network equipment; and/or the number of the groups of groups,

when the total power allowance is equal to a first preset value, first information is sent to the network equipment; and/or the number of the groups of groups,

and when the first timer is in an activated state, sending first information to the network equipment, wherein the activated state of the first timer is used for indicating that the terminal equipment is allowed to report the total power allowance.

The above steps may be combined with each other, where the combination means that the network device sends the first information only when the conditions described in the two steps are satisfied at the same time, for example, the terminal device sending the first information to the network device may include: sending first information to the network equipment according to the target period; and when the terminal equipment receives the trigger instruction sent by the network equipment, sending first information to the network equipment, wherein the first information means that the current time meets the reporting time indicated by the target period, and when the trigger instruction sent by the network equipment is received, the first information is sent to the network equipment, and other combinations are similar and are not repeated one by one.

In some alternative embodiments, if the network device configures the first threshold value and the second threshold value at the same time, the network device may activate or deactivate the second timer, so that the terminal device selects the corresponding threshold value. For example, when the second timer is in the first state, the terminal device uses the first threshold value to make a determination, that is, the reporting condition includes the condition 3, or when the total actual transmission power is greater than the first threshold value, the terminal device sends first information to the network device, when the second timer is in the second state, the terminal device uses the second threshold value to make a determination, that is, the reporting condition includes the condition 4, or when the total power margin is less than or equal to the second threshold value, the terminal device sends first information to the network device, and it may be understood that the second timer may be the same as or different from the first timer. The first state is different from the second state, for example, the first state is an active state, the second state is a deactivated state, or the first state is a deactivated state, the second state is an active state, specific states of the first state and the second state may be preconfigured by the network device, and the state of the second timer may be controlled by the network device through signaling.

Optionally, a second timer corresponding to the first threshold and a third timer corresponding to the second threshold may be set respectively, when the second timer is in an active state, the terminal device uses the first threshold to determine that the reporting condition includes the condition 3, or when the total actual transmission power is greater than the first threshold, the terminal device sends first information to the network device, and when the third timer is in an active state, the reporting condition includes the condition 4, or when the total power margin is less than or equal to the second threshold, the terminal device sends first information to the network device.

The network device may also configure a plurality of first threshold values, and/or a plurality of second threshold values, and the network device may indicate to the terminal device which first threshold value and/or which second threshold value is used for determining, where a specific indication manner may be that a signaling manner is used for indication, or that a corresponding timer is activated for indication, which is not limited in this application.

In a second alternative embodiment, when the reporting condition is met, the terminal device may send first information including indication information to the network device, where the indication information may be called a full power indication (Full power indication) or a near full power indication, the indication information may be used to indicate that the total actual transmission power of the terminal device at least one carrier has reached or is near the total configurable maximum transmission power of the terminal device at the at least one carrier, or the indication information may be used to indicate that the total actual transmission power exceeds the maximum configurable transmission power of the terminal device, or the indication information may be used to indicate that a difference between the total configurable maximum transmission power of the plurality of carriers and the total actual transmission power of the terminal device at the plurality of carriers is less than or equal to a threshold value, and if the difference is 0, the threshold value indicates that the total actual transmission power is equal to the total maximum configurable transmission power, and the indication information may be called a full power indication.

For example, the terminal device sending the report condition of the first information including the indication information may include one or more of the following:

a, the total actual transmit power is greater than a third threshold, which may be configured by the network device, or a predefined power value, such as a default value, for example, the third threshold may be 20dB;

b, the difference between the first reference power minus the total actual transmit power is less than or equal to a fourth threshold, or may also be referred to as the total actual transmit power being lower than a fourth threshold of the total configurable maximum transmit power, which may be 3dB, or 2dB, or 0, etc., which may be configured by the network device, or a predefined power value, such as a default value; as shown in fig. 5b, the position indicated by the dashed line may be a fourth threshold value, and when the difference between the first reference power and the total actual transmission power is smaller than or equal to the fourth threshold value, the terminal device sends indication information to the network device, where the first reference power is the total maximum configurable transmission power pcmax_total of the terminal device on at least one carrier;

C, the difference between the first reference power minus the total actual transmission power is equal to a second preset value, for example, the second preset value may be 0, and the first preset value may be configured by the network device, or a predefined power value, for example, a default value, as shown in fig. 5a, that is, when the difference between the first reference power and the total actual power is 0, the terminal device sends indication information to the network device, where the first reference power is the total maximum configurable transmission power pcmax_total of the terminal device on at least one carrier;

and D, the fourth timer is in an activated state, and the activated state of the fourth timer is used for indicating that the terminal equipment is allowed to report the indication information. The fourth timer may be referred to as an allow timer, i.e. the network device sets a time interval for allowing the terminal device to report the indication information by activating the fourth timer. Further, the network device may also set a time interval for preventing the terminal device from reporting the indication information by activating a corresponding preventing timer, that is, when the preventing timer is in an activated state, the terminal device is not allowed to report the indication information. It will be appreciated that the permission or prevention of reporting of the indication information by the terminal device may also be controlled by a timer, for example, the terminal device may be permitted to report the indication information when the timer is in an active state, and the terminal device may be prevented from reporting the indication information when the timer is in a deactivated state.

Optionally, in the above condition B and condition C, the first reference power is one of: the terminal equipment is configured with the total configurable maximum transmitting power of the at least one carrier; a power value configured by the network device; a predefined power value; the power value corresponding to the power class of the terminal device, i.e. the maximum configurable power available to the terminal device, is related to the power class it supports. For example, for a terminal of power class 3, its maximum configurable transmit power is 23dBm, i.e., the first reference power is 23dBm.

It may be understood that each of the conditions a-D may be combined with each other to form a reporting condition, for example, the reporting condition includes the condition a and the condition D, that is, when the fourth timer is required to be in an activated state and the total actual transmission power is greater than the third threshold, the terminal device sends first information including indication information to the network device, and other combinations are not described one by one. The network device may activate the fourth timer through RRC signaling or MAC CE or DCI, that is, if the network device activates the terminal device to report the indication information, the terminal device sends the first information to the network device. The network device may also deactivate the terminal device to report the indication information.

In some alternative embodiments, the above conditions a-D and combinations thereof may also be described as that the terminal device sending the first information to the network device may include:

when the total actual transmitting power is larger than a third threshold value, first information is sent to the network equipment; and/or the number of the groups of groups,

transmitting first information to the network device when a difference between the first reference power minus the total actual transmit power is less than or equal to a fourth threshold; and/or the number of the groups of groups,

when the difference value between the first reference power minus the total actual transmitting power is equal to a second preset value, first information is sent to the network equipment; and/or the number of the groups of groups,

and when the fourth timer is in an activated state, sending first information to the network equipment, wherein the activated state of the fourth timer is used for indicating that the terminal equipment is allowed to report the indication information.

The above steps may be combined with each other, where the combination means that the network device sends the first information only when the conditions described in the two steps are satisfied at the same time, for example, the terminal device sending the first information to the network device may include: when the total actual transmitting power is larger than a third threshold value, first information is sent to the network equipment; and when the fourth timer is in the active state, sending the first information to the network device, which means that the fourth timer is in the active state and the total actual transmitting power is greater than the third threshold value, sending the first information to the network device, and other combinations are similar and are not repeated one by one.

In some alternative embodiments, if the network device configures the third threshold value and the fourth threshold value at the same time, the network device may activate or deactivate the fifth timer, so that the terminal device selects the corresponding threshold value. For example, when the fifth timer is in the first state, the terminal device uses the third threshold value to make a determination, that is, the reporting condition includes the condition a, or when the total actual transmission power is greater than the third threshold value, first information is sent to the network device, when the fifth timer is in the second state, the terminal device uses the fourth threshold value to make a determination, that is, the reporting condition includes the condition B, or when the difference between the first reference power minus the total actual transmission power is less than or equal to the fourth threshold value, first information is sent to the network device, it may be understood that the fifth timer may be the same as or different from the fourth timer. The first state is different from the second state, for example, the first state is an active state, the second state is a deactivated state, or the first state is a deactivated state, the second state is an active state, specific states of the first state and the second state may be preconfigured by the network device, and the state without the timer may be controlled by the network device through signaling.

Optionally, a fifth timer corresponding to the third threshold value and a sixth timer corresponding to the fourth threshold value may be set respectively, when the fifth timer is in an active state, the terminal device uses the third threshold value to determine that the reporting condition includes the condition a, or when the total actual transmission power is greater than the third threshold value, first information is sent to the network device, and when the sixth timer is in an active state, the reporting condition includes the condition B, or when a difference between the first reference power minus the total actual transmission power is less than or equal to the fourth threshold value, first information is sent to the network device.

The network device may also configure a plurality of third threshold values and/or a plurality of fourth threshold values, and the network device indicates to the terminal device which third threshold value and/or which fourth threshold value is used for the determination.

In this embodiment, the first information may be sent by MAC CE, or may also be sent by UCI, or may also be sent by RRC, or the like, where the terminal device may report the indication information to the network device only when the network device configures multiple carriers for the terminal device, or may be adapted to report the indication information to the network device when the network device configures a single carrier for the terminal device. The first information may be transmitted to the network device together with a power headroom per carrier and a maximum transmit power per carrier.

For example, when the network device configures the terminal device to operate in multi-carrier transmission, the network device may send the first information through a MAC CE, where the MAC CE includes indication information full_pow, optionally, the MAC CE may further include Total configurable maximum transmission power pcmax_total, which is illustrated in fig. 6a to 6d below, where the indication information is denoted by full_pow, and the Total configurable maximum transmission power pcmax_total is denoted by Pcmax, f, c Total.

As shown in fig. 6a, the MAC CE includes indication information full_pow, which is indicated in italics in fig. 6a, i.e. one reserved bit is used to represent the indication information, and further, as shown in fig. 6a, the MAC CE may further include a power headroom of each carrier and a maximum transmittable power of each carrier.

As shown in fig. 6b, the MAC CE includes indication information full_pow and Total configurable maximum transmission power PCMAX, f, c Total, which are marked in italics in fig. 6b, and further, as shown in fig. 6b, the MAC CE may further include a power headroom of each carrier and a maximum transmittable power of each carrier.

As shown in fig. 6c and 6d, the MAC CE includes indication information full_pow and Total configurable maximum transmission power PCMAX, f, c Total, which are indicated in italics in fig. 6c and 6d, and the indication information full_pow and Total configurable maximum transmission power PCMAX, f, c Total are indicated by bits in one byte in fig. 6c and 6d, except that the indication information full_pow is located in a different position in fig. 6c and 6 d. Further, as shown in fig. 6c and 6d, the MAC CE may further include a power headroom of each carrier and a maximum transmittable power of each carrier.

In a third alternative embodiment, the terminal device may send first information to the network device, where the first information includes a total configurable maximum transmission power of the terminal device on at least one carrier, a maximum configurable transmission power of the terminal device on each carrier, and a power headroom of each carrier, where the network device receives the first information, calculates an actual transmission power of each carrier according to the maximum configurable transmission power of the terminal device on each carrier and the power headroom of each carrier, further calculates a sum of the actual transmission powers of each carrier as a total actual transmission power, and subtracts the total actual transmission power from the total configurable maximum transmission power, that is, equals to the total power headroom. As shown in fig. 7, a schematic structure diagram of a MAC CE carrying a total configurable maximum transmission power is provided in the present application.

In this embodiment, the reporting condition of the terminal device sending the first information to the network device may refer to the description of the conditions 1 to 6 in the first optional embodiment, and the reporting condition may also be a combination of the conditions 1 to 6, which is not described herein, and the first information may also be sent through the MAC CE, or may also be sent through the UCI, or may also be sent through the RRC, or may be the like, which is specifically please refer to the description of the foregoing embodiment, which is not described herein.

S102, the network equipment receives first information sent by the terminal equipment.

And S103, the network equipment schedules the transmitting power of the terminal equipment in at least one carrier according to the first information.

In this embodiment of the present application, if the first information includes a total power headroom, or the first information includes a total configurable maximum transmission power, a maximum transmission power of the terminal device on each carrier, and a power headroom of each carrier, the network device calculates the total power headroom, when the total power headroom is less than or equal to a fifth threshold, the total configurable maximum transmission power of the terminal device is less than or equal to 0, and when the base station further improves the transmission power of the multiple carriers, the base station should pay close attention to the received signal strength and the signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) of the multiple carriers. When the uplink received signal strength of the partial carrier is found to be too low or the SINR is too low, the network device should appropriately increase the transmission power of the corresponding carrier, for example, increase the transmission power of the low priority carrier, so as to avoid release due to too low transmission power of the low priority carrier. Optionally, the transmission power of the high priority carrier may be reduced to compensate for the transmission power of the low priority carrier.

Through reporting the total power margin and/or the total configurable maximum transmitting power by the terminal equipment, the network equipment can know the state of the total transmitting power of the current terminal equipment under the transmission of at least one carrier, and can adjust the transmitting power of the terminal on the low-priority carrier and the high-priority carrier under the condition of approaching to the condition of no available power so as to avoid the disconnection of the low-priority carrier.

If the first information includes the indication information, when the threshold or the preset value triggering the terminal device to send the indication information is lower than the total configurable maximum transmission power, the available total transmission power of the terminal device is small, and the base station should pay close attention to the received signal strength, SINR and the like of the multi-carrier when further improving the transmission power of the multi-carrier. When the uplink received signal strength of a part of carriers is found to be too low or the SINR is too low, the base station should appropriately increase the transmission power of the corresponding carrier, for example, increase the transmission power of the low priority carrier, so as to avoid release due to too low transmission power of the low priority carrier. Optionally, the transmission power of the high priority carrier may be reduced to compensate for the transmission power of the low priority carrier.

When the threshold or preset value triggering the terminal device to send the indication information is equal to the total configurable maximum transmission power, which means that the terminal device has no remaining transmission power, if the base station further increases the transmission power of part of carriers, the transmission power of the low priority carrier will be reduced, and at this time, the received signal strength, SINR and the like of the low priority carrier should be closely paid attention to. When the uplink received signal strength of the low priority carrier is found to be too low or the SINR is too low, the base station should consider to appropriately increase the transmission power of the low priority carrier. Optionally, the transmission power of the high priority carrier can be reduced to compensate the transmission power of the low priority carrier

Through the indication information of full power/near full power indication reported by the terminal equipment, the network equipment can know that the current terminal equipment has no available redundant transmission power under multi-carrier transmission, and needs to consider and adjust the transmission power on the low-priority carrier and the high-priority carrier in the subsequent scheduling of the base station so as to avoid the disconnection of the low-priority carrier.

It will be appreciated that the terminal device may send the total power margin, the total configurable maximum transmit power, and the indication information to the network device for scheduling by the network device. The reporting manner is referred to the description of the foregoing embodiments, and is not repeated herein.
