Description

Information transmission method, device and storage medium

technical field

The present application relates to the technical field of communication, and in particular to an information transmission method, device and storage medium.

Background technique

When a terminal device works under the combination of frequency bands, multiple carriers configured by the network share the total transmit power capability of the terminal device. The total transmit power of a terminal device on multiple carriers will not exceed the maximum configurable transmit power of the terminal device. Therefore, when the transmit power on one carrier increases, it means that the available transmit power of other carriers will decrease. When one carrier takes up all transmit power, no transmit power will be available on other carriers. There is also a priority in power usage between carriers, that is, the power requirements of high-priority carriers are met first, and then the power requirements of low-priority carriers are further satisfied. When the transmit power of a low-priority carrier cannot meet the link requirements, the carrier will be disconnected, and if the low-priority carrier is the main carrier, both the main carrier and the spoke carrier will be disconnected. Under the existing mechanism, the terminal device reports the transmit power headroom of each carrier at the granularity of the carrier, which causes the base station to only know the transmit power headroom of each carrier. When the total transmit power of the terminal device on multiple carriers has been When the maximum configurable power is reached, and the base station continues to schedule to increase the terminal transmit power, the terminal device can only reduce the transmit power of the low-priority carrier to meet the transmit power of the high-priority carrier, and eventually the transmit power Too low causes low priority carriers to be released.

In the embodiment of the present application, the network device is a device deployed in a radio access network to provide a wireless communication function for a terminal device. Network equipment may include various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, and the like. In systems using different wireless access technologies, the names of network devices may be different, such as GSM (Global System for Mobile Communication, Global System for Mobile Communication) or CDMA (Code Division Multiple Access, Code Division Multiple Access) network BTS (Base Transceiver Station, Base Transceiver Station), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access, NB (NodeB), LTE (Long Term Evolution, Long Term Evolution, eNB or eNodeB ( Evolutional NodeB). The network device can also be a wireless controller in a CRAN (Cloud Radio Access Network, Cloud Radio Access Network) scenario. The network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. A network device can also be a wearable device or an in-vehicle device. The network device can also be a transmission and reception point (TRP). A network device may also refer to a general term for all devices on the network side. For example, when multiple TRPs are used to transmit data to a terminal device, the multiple TRPs are collectively referred to as a network device.

In the embodiment of this application, the terminal device is a device with wireless transceiver function, which can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed In the air (such as aircraft, balloons and satellites, etc.).

The network architecture and business scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided by the embodiments of the present application. For the evolution of architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

Based on the network architecture shown in FIG. 1 , the information transmission method provided by the embodiment of the present application will be described in detail below. During the introduction, the names of the information exchanged between the network device and the terminal device are used as examples, and do not constitute a limitation to the embodiment of the present application.

When the terminal device works under the combination of carrier aggregation (Carrier Aggregation, CA), LTE NR dual connectivity (LTE NR dual connectivity, EN-DC), dual connectivity (Dual Connectivity, DC) and other frequency band combinations, the terminal device is on multiple carriers The total transmit power of the device will not exceed the maximum transmit power configurable by the terminal device. Therefore, when the transmit power on one carrier increases, it means that the transmit power available on other carriers will decrease. When one carrier takes up all transmit power, no transmit power will be available on other carriers.

Exemplarily, the terminal device needs to transmit on the primary carrier component (PCC) and the secondary carrier (secondary carrier component, SCC) at the same time. If the primary carrier occupies most of the power, the transmission power on the secondary carrier is too high. Too small to maintain an uplink will result in a situation where the SCC link is down, ie only the PCC is working. For example, the network usually configures RB resources and schedules modulation and coding MCS according to the signal quality on the carrier. When the terminal device is in the center of the cell and the signal quality of the PCC is relatively good, the network will allocate more RBs and schedule a higher MCS, so that the UE transmits high power on the PCC. At this time, because the priority of the SCC is lower than that of the PCC, only the remaining power can be used. The transmission power of the PCC is too high, which makes it difficult to maintain the link and the SCC link fails. In contrast, if both PCC and SCC can maintain the link for communication, the overall throughput will be better than that of PCC transmitting alone.

In addition to the above, the relative priority between multiple carriers is also affected by many factors, including the type of channel transmitted on the carrier (such as PUSCH and PUCCH have higher priority than SRS, etc.), the service content carried by the channel (such as PUSCH The relative priority of the PUCCH is related to whether it bears control information or service information, etc.), the network directly indicates the priority (for example, the network indicates whether the carrier is of high priority or low priority through signaling), etc. Therefore, when the SCC has a higher priority, the terminal allocates most of the power to the SCC for transmission, which will cause the PCC to go offline, causing the terminal to disconnect from the network, because if the PCC goes offline, the SCC will also go offline.

Under the current frequency band combination, NR will first use power for higher priority carriers, and then allocate the remaining power to low priority carriers. Therefore, when the high-priority carrier takes up most or all of the power, the low-priority carrier will drop the connection. Furthermore, under the combination of frequency bands such as CA, the priority of the PCC may be lower than that of the SCC, so the problem is that once the power of the PCC cannot maintain the link, both the PCC and the SCC will be disconnected.

In order to solve the above technical problems, the terminal device of this application will report the total power headroom or indication information to the network device. The total power headroom is the total configurable maximum transmit power of the terminal device on multiple carriers and the total power The difference of the actual transmit power, the indication information is used to indicate that the total actual transmit power is close to or reaches the maximum transmit power configurable by the terminal equipment, or the indication information can also be used to indicate that the total actual transmit power exceeds the configurable maximum transmit power of the terminal equipment The configured maximum transmit power, or, the indication information may also be used to indicate the difference between the total configurable maximum transmit power of the terminal device on the multiple carriers and the total actual transmit power of the terminal device on the multiple carriers The difference between them is less than or equal to the threshold value and so on. The network device may schedule the transmit power of the terminal device on multiple carriers according to the total power headroom or indication information, for example, increase the transmit power of a low priority carrier, and/or decrease the transmit power of a high priority carrier, In this way, when the high-priority carrier occupies most or all of the total configurable maximum transmit power, the network device continues to schedule to increase the transmit power of the terminal device (for example, continue to increase the transmit power of the high-priority carrier or continue to increase all The low-priority carrier is released when the transmission power of the carrier) is caused by the technical problem, because the terminal device can only meet the transmission power of the high-priority carrier by reducing the transmission power of the low-priority carrier. The process of the information transmission method of the present application will be described in detail below with reference to FIG. 2 .

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

S101. The terminal device sends first information to the network device, where the first information includes total power headroom or indication information, and the total power headroom is based on the total configurable maximum transmit power of the terminal device on multiple carriers and the determined by the total actual transmit power of the terminal device on the multiple carriers, and the indication information is used to indicate that the total configurable maximum transmit power of the terminal device on the multiple carriers is different from the total configurable maximum transmit power of the terminal device on the multiple carriers The difference between the total actual transmit power of the carriers is less than or equal to the threshold value.

In this embodiment of the present application, it may be applicable to the scenario where a terminal device transmits data on one or more carriers, and the total actual transmission power of the terminal device on the one or more carriers is less than or equal to the total transmission power of the terminal device on the at least one carrier. The configurable maximum transmit power of the terminal device, where the total configurable maximum transmit power of the terminal device on the at least one carrier may also be referred to as the configurable maximum transmit power of the terminal device. The total actual transmit power of the terminal device on multiple carriers is equal to the sum of the actual transmit power of the terminal device on each carrier. In order for the network device to know the relationship between the total actual transmit power and the total configurable maximum transmit power, and to avoid that the network device continues to schedule and increase the terminal device when the total actual transmit power reaches or exceeds the total configurable maximum transmit power In this application, the terminal device can report the total power headroom or indication information to the network device through the first information. In some optional ways, the terminal device can also pass the first The information reports the total configurable maximum transmit power, the maximum transmit power of each carrier, and the power headroom of each carrier to the network device, so that the network device can calculate the total power headroom. For example, the network device can configure the terminal device to report the total One or more of the configurable maximum transmit power, total power headroom, or indication information. It will be described separately below. It should be noted that in the embodiment of the present application, the first information may be reported through auxiliary information, that is, one or more of the total configurable maximum transmit power, total power headroom, or indication information may be reported through auxiliary information. item.

In the first optional implementation manner, the terminal device may calculate the total power headroom PHR_total according to the total configurable maximum transmit power Pcmax_total of the terminal device on at least one carrier and the total actual transmit power of the terminal device on at least one carrier. The power headroom PHR_total is the total transmit power headroom of the terminal device when transmitting on at least one carrier, which can be defined as the difference between the total configurable maximum transmit power Pcmax_total and the total actual transmit power, as illustrated in Figure 3 , the terminal device transmits on the carrier CC1 and the carrier CC2, wherein, the actual transmit power of the carrier CC1 is Pow_cc1, and the actual transmit power of the carrier CC2 is Pow_cc2, then the total actual transmit power is Pow_cc1+Pow_cc2, the total power headroom=Pcmax_total -(Pow_cc1+Pow_cc2), further, the terminal device sends first information to the network device, where the first information includes the total power headroom.

Further, in order to facilitate the network device to schedule the transmit power of each carrier, the first information may also include the total configurable maximum transmit power Pcmax_total. Optionally, the network device may configure whether the terminal device reports the total configurable maximum transmit power Pcmax_total.

In this implementation manner, the first information may be sent through a Media Access Control (MAC) control element (Control Element, CE), or may also be sent through uplink control information (Uplink Control Information, UCI). transmission, or can also be transmitted through radio resource control (radio resource control, RRC), etc., where the terminal device can report the total power surplus to the network device only when the network device configures multiple carriers for the terminal device It can also be applied to when the network device configures a single carrier for the terminal device, and the terminal device reports the total power headroom to the network device. The first information may be sent to the network device together with the power headroom of each carrier and the maximum transmit power of each carrier.

Exemplarily, when the network device configures the terminal device to work on multi-carrier transmission, the network device can send the first information through the MAC CE, the MAC CE includes the total power headroom PHR_total, optionally, the MAC CE can also include the total power headroom PHR_total The configurable maximum transmission power Pcmax_total of , is illustrated below in conjunction with accompanying drawings 4a and 4b, wherein, in Fig. 4a and Fig. 4b, the total power headroom PHR_total is represented by PH(Type X, Total), and the total configurable maximum The transmit power Pcmax_total is represented by PCMAX,f,c Total.

As shown in Figure 4a, the MAC CE includes a total power headroom PH (Type X, Total), and PH (Type X, Total) is marked in italics in Figure 4a, further, as shown in Figure 4a, the MAC CE also It may include the power headroom of each carrier and the maximum transmittable power of each carrier.

As shown in Figure 4b, the MAC CE includes the total power headroom PH(Type X,Total) and the total configurable maximum transmit power PCMAX,f,c Total, PH(Type X,Total) and PCMAX,f,c Total Identified in italics. Further, as shown in FIG. 4b, the MAC CE may also include the power headroom of each carrier and the maximum transmittable power of each carrier.

Exemplarily, when the reporting condition is met, the terminal device may send the first information including the total power headroom to the network device, where the reporting condition may include one or more of the following:

1. The current time meets the reporting time indicated by the target period, and the target period is the reporting period of the total power headroom, that is, the total power headroom is reported periodically;

2. The terminal device receives a trigger instruction sent by the network device, the trigger instruction is used to trigger the terminal device to report the total power headroom to the network device, and the trigger instruction may be RRC signaling or MAC CE or physical layer DCI, etc. It is understandable that the network device can also trigger the terminal device to stop reporting the total power headroom through trigger signaling. Among them, triggering the terminal device to report the total power The terminal device that stops reporting the total power headroom can be called a deactivation reporting instruction;

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

4. The total power headroom is less than or equal to the second threshold value, or the total actual transmit power is lower than the second threshold value of the total configurable maximum transmit power, and the second threshold value may be 3dB, or 2dB, or 0, etc., which are not limited in this application, and the second threshold value can be configured by the network device, or a predefined power value, such as a default value;

5. The total power headroom is equal to a first preset value, the first preset value may be 0dB, and the first preset value 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, and the active state of the first timer is used to indicate that the terminal device is allowed to report the total power headroom. The first timer may be called an allowable timer, That is, 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 can also set the time interval for preventing the terminal device from reporting the total power headroom and/or the total configurable maximum transmit power by activating the corresponding blocking timer, that is, when the blocking timer is activated, the terminal is not allowed to The device reports the total power headroom and/or the total configurable maximum transmit power. It can be understood that a timer can also be used to control allowing or preventing the terminal device from reporting the total power headroom and/or the total configurable maximum transmit power. For example, when the timer is active, the terminal device is allowed to report the total The power headroom and/or the total configurable maximum transmit power, when the timer is in the deactivated state, prevent the terminal device from reporting the total power headroom and/or the total configurable maximum transmit power.

It can be understood that the above-mentioned conditions 1-6 can be combined to form a reporting condition. For example, if the terminal device reports the first information semi-continuously, the network device configures the target period, and needs to meet the reporting conditions indicated by the target period at the same time. The terminal device reports the first information only when the time and the trigger instruction sent by the network device are received, that is, the reporting condition includes the above-mentioned condition 1 and condition 2. For another example, the reporting conditions include the above-mentioned condition 3 and condition 6, that is, when the first timer is required to be in an active state, and the total actual transmit power is greater than the first threshold, the terminal device sends the first information to the network device, and other combinations do not Describe them one by one.

In some optional implementation manners, the above conditions 1-6 and their combinations may also be described as, the terminal device sending the first information to the network device may include:

sending the first information to the network device according to the target period; and/or,

When the terminal device receives the trigger instruction sent by the network device, send the first information to the network device; and/or,

When the total actual transmission power is greater than a first threshold value, sending first information to the network device; and/or,

When the total power headroom is less than or equal to a second threshold value, sending first information to the network device; and/or,

When the total power headroom is equal to a first preset value, sending first information to the network device; and/or,

When the first timer is in an active state, sending first information to the network device, where the active state of the first timer is used to indicate that the terminal device is allowed to report the total power headroom.

The above steps can be combined with each other. The combination means that the network device can send the first information only when the conditions described in the two steps are met at the same time. For example, the terminal device can send the first information to the network device. sending the first information to the network device; and, when the terminal device receives the trigger instruction sent by the network device, sending the first information to the network device, which means that the current time meets the reporting time indicated by the target period , and the trigger instruction sent by the network device is received, the first information is sent to the network device, and the other combinations are similar and will not be described one by one.

In some optional implementations, if the network device configures the first threshold and the second threshold at the same time, the network device can activate or deactivate the second timer, so that the terminal device selects the corresponding gate limit. For example, when the second timer is in the first state, the terminal device uses the first threshold value to make a decision, that is, the reporting condition includes the above condition 3, or, when the total actual transmit power is greater than the first threshold value, The terminal device sends the first information to the network device, and when the second timer is in the second state, the terminal device uses the second threshold value to judge, that is, the reporting condition includes the above condition 4, or, when the total power remaining When the amount is less than or equal to the second threshold, the first information is sent to the network device. It can be understood that the second timer may be the same as or different from the first timer. Wherein, the first state is different from the second state, for example, if the first state is an active state, then the second state is a deactivated state, or if the first state is a deactivated state, then the second state is an activated state, and the first state The specific state of the second state and the second state may be pre-configured by the network device, and the state of the second timer may be controlled by the network device through signaling.

Optionally, the second timer corresponding to the first threshold and the third timer corresponding to the second threshold can also be set respectively. When the second timer is active, the terminal device uses the first gate limit value, that is, the reporting condition includes the above condition 3, or, when the total actual transmit power is greater than the first threshold value, the terminal device sends the first information to the network device, and when the third timer is activated state, the reporting condition includes the above condition 4, or, when the total power headroom is less than or equal to the second threshold, the first information is sent to the network device.

Wherein, the network device can also be configured with multiple first threshold values, and/or, multiple second threshold values, and the network device can indicate to the terminal device which first threshold value and/or which second threshold value to use The limit value is determined, and the specific indication method may be through signaling, or through activating a corresponding timer, which is not limited in this application.

In the second optional implementation manner, when the reporting condition is met, the terminal device may send the first information including indication information to the network device, where the indication information may be called full power indication (Full power indication) or close to full power indication, the indication information may be used to indicate that the total actual transmit power of the terminal device on at least one carrier has reached or approached the total configurable maximum transmit power of the terminal device on at least one carrier, or the indication information may also be used to Indicate that the total actual transmit power exceeds the configurable maximum transmit power of the terminal device, or the indication information may also be used to indicate that the total configurable maximum transmit power of the terminal device on the multiple carriers is different from that of the terminal device on the multiple carriers. The difference between the total actual transmit power of the multiple carriers is less than or equal to the threshold value, etc. If the threshold value is 0, when the difference is equal to 0, it means that the total actual transmit power is equal to the total maximum possible To configure the transmit power, the indication information may be referred to as a full power indication.

Exemplarily, the reporting condition for the terminal device to send 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 value, the third threshold value may be configured by the network device, or a predefined power value, such as a default value, for example, the third threshold value may be is 20dB;

B. The difference between the first reference power minus the total actual transmit power is less than or equal to the fourth threshold value, or it can also be referred to as the total actual transmit power lower than the total configurable maximum transmit power. Four threshold values, the fourth threshold value can be 3dB, or 2dB, or 0, etc., the fourth threshold value can be configured by the network device, or a predefined power value, such as a default value; as shown in Figure 5b As shown, the position indicated by the dotted line may be the fourth threshold value. When the difference between the first reference power and the total actual transmission power is less than or equal to the fourth threshold value, the terminal device sends an indication to the network device Information, the first reference power is the total maximum configurable transmit 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 the 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, such as a default value, as shown in Figure 5a, that is, when the difference between the first reference power and the total actual power is 0, the terminal device sends an instruction message to the network device, the first reference The power is the total maximum configurable transmit power Pcmax_total of the terminal device on at least one carrier;

D. The fourth timer is in an activated state, and the activated state of the fourth timer is used to indicate that the terminal device is allowed to report the indication information. The fourth timer may be called a permission timer, that is, 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 can also set a time interval for preventing the terminal device from reporting the indication information by activating a corresponding prevention timer, that is, when the prevention timer is in an activated state, the terminal device is not allowed to report the indication information. It can be understood that a timer can also be used to control the permission or prevention of the terminal device to report the indication information, for example, when the timer is activated, the terminal device is allowed to report the indication information; when the timer is in the deactivated state, Prevent terminal devices from reporting indication information.

Optionally, in the above condition B and condition C, the first reference power is one of the following: the total configurable maximum transmission power of the terminal device on the at least one carrier; Power value; a predefined power value; the power value corresponding to the power level of the terminal device, that is, the maximum configurable power available to the terminal device is related to its supported power level. For example, for a power class 3 terminal, its maximum configurable transmit power is 23dBm, that is, the first reference power is 23dBm.

It can be understood that the above-mentioned conditions A-D can be combined to form a reporting condition. For example, the reporting condition includes the above-mentioned condition A and condition D, that is, the fourth timer needs to be activated, and the total actual transmission power is greater than the third gate. When the limit value is reached, the terminal device sends the first information including the indication information to the network device, and other combinations are not described one by one. Wherein, the network device can activate the fourth timer through RRC signaling or MAC CE or DCI, that is, when 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 optional implementation manners, the above conditions A-D and their combinations may also be described as, the terminal device sending the first information to the network device may include:

When the total actual transmission power is greater than a third threshold value, sending first information to the network device; and/or,

When the difference between the first reference power minus the total actual transmit power is equal to a second preset value, sending the first information to the network device; and/or,

When the fourth timer is in an activated state, the first information is sent to the network device, and the activated state of the fourth timer is used to indicate that the terminal device is allowed to report the indication information.

The above steps can be combined with each other. The combination means that the network device can send the first information only when the conditions described in the two steps are met at the same time. For example, the terminal device can send the first information to the network device. When the total actual transmission power is greater than the third threshold value, sending the first information to the network device; and, when the fourth timer is active, sending the first information to the network device, which means, the fourth If the timer is active and the total actual transmit power is greater than the third threshold, then the first information is sent to the network device, and other combinations are similar, and will not be described one by one.

In some optional implementations, if the network device configures the third threshold and the fourth threshold at the same time, the network device can activate or deactivate the fifth timer, so that the terminal device selects the corresponding threshold limit. For example, when the fifth timer is in the first state, the terminal device uses the third threshold value to make a decision, that is, the reporting condition includes the above condition A, or, when the total actual transmit power is greater than the third threshold value , to send the first information to the network device, when the fifth timer is in the second state, the terminal device uses the fourth threshold value to judge, that is, the reporting condition includes the above-mentioned condition B, or, when the first reference power minus When the difference between the total actual transmit powers is less than or equal to a fourth threshold, the first information is sent to the network device. It can be understood that the fifth timer may be the same as the fourth timer or different. Wherein, the first state is different from the second state, for example, if the first state is an active state, then the second state is a deactivated state, or if the first state is a deactivated state, then the second state is an activated state, and the first state The specific state of the second state and the second state may be pre-configured by the network device, and the state of the second state without a timer may be controlled by the network device through signaling.

Optionally, a fifth timer corresponding to the third threshold and a sixth timer corresponding to the fourth threshold can also be set respectively. When the fifth timer is active, the terminal device uses the third threshold limit value, that is, the reporting condition includes the above condition A, or, when the total actual transmit power is greater than the third threshold value, send the first information to the network device, and when the sixth timer is active, Then the reporting condition includes the above condition B, or, when the difference between the first reference power minus the total actual transmit power is less than or equal to a fourth threshold, the first information is sent to the network device.

Wherein, the network device may also configure multiple third thresholds and/or multiple fourth thresholds, and the network device indicates to the terminal device which third threshold and/or which fourth threshold to use value is judged.

In this implementation manner, the first information may be sent through MAC CE, or may also be sent through UCI, or may also be sent through RRC, etc., where the network device may configure multiple carriers for the terminal device Only when the terminal device reports the indication information to the network device, it is also applicable to when the network device configures a single carrier for the terminal device, the terminal device reports the indication information to the network device. The first information may be sent to the network device together with the power headroom of each carrier and the maximum transmit power of each carrier.

Exemplarily, when the network device configures the terminal device to work on multi-carrier transmission, the network device can send the first information through the MAC CE, which includes the indication information Full_Pow, and optionally, the MAC CE can also include the total available Configuring the maximum transmit power Pcmax_total is illustrated below with reference to Figures 6a to 6d, wherein the indication information in Figures 6a to 6d is represented by Full_Pow, and the total configurable maximum transmit power Pcmax_total is represented by PCMAX,f,c Total.

As shown in Figure 6a, the MAC CE includes indication information Full_Pow, the indication information Full_Pow is marked in italics in Figure 6a, that is, a reserved bit is used to represent the indication information, further, as shown in Figure 6a, the MAC CE It may also include the power headroom of each carrier and the maximum transmittable power of each carrier.

As shown in Figure 6b, the MAC CE includes the indication information Full_Pow and the total configurable maximum transmission power PCMAX,f,c Total, the indication information Full_Pow and the total configurable maximum transmission power PCMAX,f,c are shown in Figure 6b as Marked in italics, further, as shown in Figure 6b, the MAC CE may also include the power headroom of each carrier and the maximum transmittable power of each carrier.

As shown in Figure 6c and Figure 6d, the MAC CE includes the indication information Full_Pow and the total configurable maximum transmission power PCMAX, f, c Total, the indication information Full_Pow and the total configurable maximum transmission power PCMAX, f, c are shown in Fig. 6c and Figure 6d are marked in italics, and Figure 6c and Figure 6d use bits in one byte to represent the indication information Full_Pow and the total configurable maximum transmit power PCMAX,f,c Total, the difference is that Figure 6c and Figure 6d The location of the indication information Full_Pow is different. Further, as shown in Figure 6c and Figure 6d, the MAC CE may also include the power headroom of each carrier and the maximum transmittable power of each carrier.

In a third optional implementation manner, the terminal device may send first information to the network device, where the first information includes the total configurable maximum transmit power of the terminal device on at least one carrier, the maximum configurable transmit power of the terminal device on each carrier power and the power headroom of each carrier, the network device receives the first information, and calculates the actual transmit power of each carrier according to the maximum configurable transmit power of the terminal device on each carrier and the power headroom of each carrier, and further calculates the The sum of the actual transmit power, as the total actual transmit power, is the total configurable maximum transmit power minus the total actual transmit power, which is equal to the total power headroom. As shown in FIG. 7 , it is a schematic structural diagram of a MAC CE carrying the total configurable maximum transmission power provided by the present application.

S102. The network device receives first information sent by the terminal device.

S103. The network device schedules transmit power of the terminal device on at least one carrier according to the first information.

In the embodiment of this application, if the first information includes the total power headroom, or the first information includes the total configurable maximum transmit power, the maximum transmit power of the terminal device on each carrier, and the power headroom of each carrier, the network device calculates the total Power headroom, when the total power headroom is less than or equal to the fifth threshold, the total configurable maximum transmit power of the terminal equipment is already very little or 0, and the base station should pay close attention to it when further increasing the transmit power of multi-carriers Received signal strength of multi-carrier and signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), etc. When it is found that the uplink received signal strength of some carriers is too low or the SINR is too low, the network device should appropriately increase the transmit power of the corresponding carrier, such as increasing the transmit power of the low priority carrier, to avoid the release of the low priority carrier due to the low transmit power . Optionally, the transmit power of the high-priority carrier may also be reduced to make up for the transmit power of the low-priority carrier.

By reporting the total power headroom and/or the total configurable maximum transmit power of the terminal device, the network device can know the current state of the total transmit power of the terminal device under at least one carrier transmission, and can adjust it when there is no available power The transmit power of the terminal on the low-priority carrier and the high-priority carrier, so as to avoid the low-priority carrier from being dropped.

When it is found that the uplink received signal strength of some carriers is too low or the SINR is too low, the base station should appropriately increase the transmit power of the corresponding carrier, such as increasing the transmit power of the low-priority carrier, so as to avoid the release of the low-priority carrier because the transmit power is too low. Optionally, the transmit power of the high-priority carrier may also be reduced to make up for the transmit power of the low-priority carrier.

When the threshold or preset value that triggers the terminal device to send indication information is equal to the total configurable maximum transmit power, it means that the terminal device has no remaining transmit power. If the base station further increases the transmit power of some carriers, it will lead to low-priority carriers. The transmit power is reduced. At this time, pay close attention to the received signal strength and SINR of the low-priority carrier. When the uplink received signal strength or SINR of the low-priority carrier is found to be too low, the base station shall consider appropriately increasing the transmit power of the low-priority carrier. Optionally, the transmit power of the high-priority carrier can also be reduced to compensate for the transmit power of the low-priority carrier

By reporting the indication information of full power/close to full power indication by the terminal device, the network device can know that the current terminal device has no available redundant transmit power under multi-carrier transmission, and the base station needs to consider adjusting low-priority carriers and high-priority carriers in subsequent scheduling.
