Additionally, various aspects or features of the present application may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques. The term "article of manufacture" as used in this application covers a computer program accessible from any computer readable device, carrier or media. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disk, floppy disk, or tape, etc.), optical disks (e.g., compact disc (compact disc, CD), digital versatile disc (digital versatile disc, DVD) etc.), smart cards and flash memory devices (for example, erasable programmable read-only memory (EPROM), card, stick or key drive, etc.).

The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing and/or carrying instructions and/or data.

For the convenience of description, terms involved in the embodiments of the present application will be firstly described below.

1. Maximum permissible exposure (MPE): refers to the maximum level of radio frequency radiation that allows the human body to be exposed to no harm to the human body.

This type of allowable value can be represented by the field quantity or power density (power density, PD) of the electromagnetic field. The safe value of MPE is formulated so that the corresponding specific absorption rate (SAR) value cannot exceed its limit no matter what the exposure conditions are. In high-frequency bands, such as millimeter waves above 6G, safety standards are usually represented by MPE. The FCC MPE can be limited to 1 milliwatt per square centimeter (mW/cm2).

Optionally, the MPE can also be used to measure whether the radiation intensity of the terminal equipment exceeds the safety standard.

2. Theoretical hazard zone (nominal hazard zone, NHZ): The area determined according to the beam emission angle, emission power, and beam diameter. In this area, the transmit power of the UE exceeds the requirement of the MPE. Therefore, if the UE detects that there are people in the area, the UE needs to adjust the transmission power to meet the requirements of the MPE. For example, the UE can reduce the transmission power or even turn off the transmission beam.

3. Radio link failure (RLF)

In order to avoid the connection failure caused by the unreasonable configuration of network equipment handover parameters, the mobility robustness optimization (MRO) mechanism is introduced in LTE. The MRO mechanism is to record and report the parameters in the process of mobility failure to the UE. Network, so that network devices can better identify the configuration problems of their mobility parameters, and optimize mobility-related parameters in a timely manner, reducing the failure rate of UEs and improving the handover success rate.

Specifically, at least one of the following failure information is included in the record report of the current MRO (which may be referred to as a radio link failure report RLF report):

(1) failedPcellID: the information of the cell where the UE detected RLF, or the information of the target cell where the handover failed;

(2) connectionFailureType: radio link failure RLF or handover failure (handover failure, HOF) or timer expiration (the timer is the timer started after the UE sends the measurement report, such as T312);

(3) previousPCellId: the information of the source cell that the UE received the handover command last time.

(4) reestablishmentCellId: information about the cell that initiates re-establishment after the connection fails;

(5) timeConnFailure: the time from the last receipt of the handover (handover, HO) command to the connection failure;

(6) timeSinceFailure: the length of time to start recording when the connection fails. Generally, it refers to the time from connection failure to reporting RLF-report.

It should be noted that the cell information may include a cell global identity (CGI), and/or a physical cell ID+frequency (physical cell ID+frequency, PCI+freq). In addition, the RLF report may also carry the cell quality of each cell, such as the failed cell and/or the cell quality of a neighboring cell when a failure is detected. Optionally, the cell information may also include cell measurement results.

It should be understood that when the UE fails to connect, the UE will record the RLF report; when the UE fails to connect again, the UE clears the previously recorded RLF report and records the latest RLF report;

Fig. 3 is a schematic diagram of a comparison before and after a UE applying the present application adjusts transmit power according to the MPE. As shown in Figure 3, taking a multi-antenna UE as an example, the theoretical danger zone NHZ is determined according to the beam angle, transmit power, and beam diameter. Can cause radiation damage to the human body. When the transmit power E of the UE is greater than the requirement of the MPE, radiation damage to the human body will occur. Therefore, if the UE detects that there are people in the area, the UE needs to adjust the transmission power to meet the requirements of the MPE, for example, the UE can reduce the transmission power or even turn off the transmission beam.

It should be noted that this application is applicable to the UE having the capability of autonomously adjusting transmit power according to the MPE.

Therefore, when the UE detects a person (or object) in the theoretical danger zone NHZ, the UE will automatically reduce the UL power so that the person (or object) is exposed to radio frequency radiation that is harmless to the human body, that is, the UE transmit power E should be less than or equal to the maximum allowable radiation dose. However, reducing the UL transmit power of the UE may cause the following problems:

(1) UL power reduction during the handover process leads to RACH failure, which in turn leads to handover failure HOF.

(2) UL power reduction will cause RLF caused by various UL problems, such as radio link control protocol (radio link control protocol, RLC) retransmission reaches the maximum number of times or RACH failure.

(3) UL power reduction leads to potential failed successful handover problem. Assuming that the handover time limit of the UE is 20 ms at the beginning, due to the reduction of UL power, the UE handover succeeds only after 19 ms, and this situation is considered as a potential failed successful handover problem. The UE can record it in the successful handover report (successful handover report).

(4) If the UE records and reports the RLF report corresponding to the RACH failure, or the successful handover report generated by the successful handover of the potential failure, it will cause the network device to mistakenly believe that it is the impact of mobility (for example, the position of the UE or the human body changes ) to adjust the mobility parameters, and then cause the mobility parameters to be inconsistent with the actual situation, because these problems may be caused by UE UL power adjustment.

(5) The network device allocates resource blocks (resource blocks, RB) to the UE according to the power headroom (PH) value of the UE. After the UE reduces the uplink power due to MPE, if the calculation method of PH is not updated in time, the network The device will think that the UE is far from reaching its maximum power, so the base station will allocate an unreasonable amount of RB resources to the UE. But in fact, the UE may have reached its allowed maximum power due to the limitation of the MPE at this time.

To sum up, the UE adjusts the UL transmit power according to the MPE requirements. For example, the UE reduces the UL transmit power, which may lead to UL failure (RACH failure due to too low UL power during UE handover, which in turn leads to handover failure HOF) or radio link failure RLF (RLF caused by too low UL power, such as the maximum number of RLC retransmissions or RACH failures, etc.), may also cause potential failed successful handover problems; if the UE records the corresponding RLF report or successful handover report, it will cause the network Incorrectly tuned mobility parameters. However, there is currently no solution for how to solve the above-mentioned problems caused by adjusting the transmission power based on the MPE, and ensure that the network equipment performs reasonable uplink scheduling and resource allocation for the terminal equipment.

In view of this, the present application provides a communication method and a communication device. When the UL power of the UE is reduced after the MPE is adjusted, the UE reports the MPE-related information and the power headroom PH related information to the base station when the UE performs the MPE function. The information mechanism enables the network device to further optimize uplink scheduling and resource allocation; and, after the UE performs the MPE function, and detects the RLF caused by HOF/or UL failure, the UE can record or not record the MPE-related mobility report mechanism, In this way, it is possible to prevent the network device from configuring unreasonable mobility parameters due to the mobility problem caused by the MPE. That is to solve the RACH problem, RLF problem, potential failed successful handover problem caused by the low UL power of the UE after MPE adjustment, and the problem of unreasonable adjustment of mobility parameters by network equipment.

In addition, specific indication manners may also be various existing indication manners, such as but not limited to, the above indication manners and various combinations thereof. For specific details of various indication manners, reference may be made to the prior art, which will not be repeated herein. It can be known from the above that, for example, when multiple pieces of information of the same type need to be indicated, there may be a situation where different information is indicated in different ways.

In this way, the indication method involved in the embodiment of the present application should be understood as covering the There are various methods by which a party can obtain the information to be indicated.

Wherein, the sending cycle and/or sending timing of these sub-information may be predefined, for example, pre-defined according to a protocol, or may be configured by the transmitting end device by sending configuration information to the receiving end device. Wherein, the configuration information may be, for example but not limited to: one or a combination of at least two of radio resource control signaling, media access control (media access control, MAC) layer signaling, and physical layer signaling.

Corresponding processing will be made, which is not a time limit, nor does it require devices (such as terminal devices or network devices) to take judgment actions during implementation, nor does it mean that there are other restrictions.

The communication method in the embodiment of the present application will be described in detail below with reference to the accompanying drawings. Exemplarily, the embodiments of the present application are described by taking a base station as a network device and a UE as a terminal device as an example.

FIG. 4 is a schematic diagram of an example of a communication method applicable to the embodiment of the present application, and the specific implementation step 400 includes:

S410, the terminal device enables the first function.

Wherein, the first function is used to adjust the uplink transmission power according to the maximum allowable radiation amount MPE.

Further, enabling the first function may also be triggering, activating the first function, etc., which is not specifically limited in the present application.

It should be noted that the MPE needs to be obtained before the terminal device enables the first function. Moreover, after enabling the first function, the terminal device also needs to compare its own transmission power with the MPE, and then adjust the uplink transmission power according to the requirements of the MPE.

Exemplarily, the MPE may be predefined by the protocol, or the network device notifies the terminal device of the maximum allowable radiation that the cell can withstand, etc., which is not specifically limited in this application.

S420. The terminal device sends the first information to the network device.

Correspondingly, the network device receives the first information from the terminal device.

Wherein, the first information is determined according to the uplink transmission power adjusted by the MPE after the terminal device starts the first function.

It should be understood that the uplink transmission power adjusted according to the MPE may be understood as: the magnitude of the uplink transmission power adjusted according to the MPE. For example, after enabling the first function, the terminal device reduces the uplink transmission power by 3dB, that is, -3dB due to the influence of the MPE; or increases the uplink transmission power by 2dB, that is, +2dB, etc. That is to say, the first information sent by the terminal device to the network device is determined according to the magnitude of the uplink transmission power adjusted by the MPE.

Optionally, the uplink transmission power adjusted according to the MPE may also be understood as: the uplink transmission power adjusted according to the MPE. For example, the uplink transmission power of the terminal device is X dB when the first function is not enabled. After the first function is enabled, the uplink transmission power is reduced by 3dB due to the influence of the MPE, then the adjusted uplink transmission power is ( X-3) dB. That is to say, the first information sent by the terminal device to the network device is determined according to the magnitude of the uplink transmission power adjusted by the MPE.

It should be noted that after the first function is enabled, when the terminal device adjusts the uplink transmission power according to the MPE, for example, the uplink transmission power is reduced, so that the MPE function activation information and/or the power headroom PH information changes, and then determine received the first information.

That is, the first information may include MPE function enablement information and/or power headroom information.

Wherein, the MPE function enabling information includes at least one of the following information: uplink beam information affected by the MPE, maximum uplink transmission power of the terminal equipment after the first function is enabled, and the like. Wherein, the uplink beam information includes at least one of the following information: beam ID, beam transmit power, beam transmit angle, and beam diameter.

In addition, the power headroom information includes at least one of the following information: uplink power headroom affected by the MPE, maximum uplink transmission power of the terminal device after the first function is enabled, and the like.

In the embodiment of this application, the uplink power headroom PH _MPE satisfies:

PH _MPE =P _{max_MPE} -P _{PUSCH_MPE}

Wherein, P _{max_MPE} is the maximum uplink transmission power of the terminal equipment after enabling the first function, and P _{PUSCH_MPE} is the transmission power of the physical uplink shared channel PUSCH of the terminal equipment after enabling the first function.

In a possible implementation manner, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device. And, the terminal device enables the first function according to the indication information.

Wherein, the indication information may be 1 bit indication information used to instruct the terminal device to enable the first function, and/or the indication information is used to indicate a condition for enabling the first function.

In this embodiment of the present application, the condition for enabling the first function may include: the terminal device detects that there are people and/or objects in the theoretical danger zone NHZ.

Further, the enabling condition may also include that within the first period of time, the terminal device detects that there are always people and/or objects in the NHZ. Wherein, the first period of time may be 5 ms, etc., which is not specifically limited in the present application. That is, if the terminal device detects people and/or objects in the NHZ within 5 ms consecutively, then the terminal device needs to enable the first function, and adjust its own uplink transmission power according to the requirements of the MPE.

Specifically, the terminal device can generate a timer when detecting someone in the NHZ, and start to adjust the UL power according to the MPE requirement when the value of the timer exceeds 5 ms. If the end device detects that there is no person or object in the NHZ when the timer has not exceeded 5ms, the timer will be reset.

As an example but not a limitation, the network device sends the indication information to the terminal device, the indication information may be sent periodically, or the indication information may be unicast or broadcast. This application does not specifically limit it.

In another possible implementation manner, the terminal device sends capability information to the network device.

Correspondingly, the network device receives capability information from the terminal device. Moreover, in a case that the network device itself has an MPE-related function, it determines indication information for instructing the terminal device to enable the first function according to the capability information.

Wherein, the capability information is used to indicate that the terminal device supports the first function.

It should be noted that, indicating whether the terminal device supports the ability of the MPE to adjust the transmit power may be 1-bit indication information. The decision right of this 1 bit depends on the hardware condition of the terminal device, indicating whether the terminal device has this capability. For example, whether the terminal device has the ability to detect whether there is an obstruction in the NHZ, and whether it can determine whether the obstruction is a human body; if it cannot detect, it cannot determine whether there is a person in the NHZ, and thus cannot support MPE-related capabilities.

Optionally, the terminal device can report the capability information to the network device during initial access; during the handover process, the source network device can also send the MPE-related functions of the terminal device to the target network device, for example, in the handover request information (handover request message).

As an example but not a limitation, the sending and receiving of the first information may include the following possible implementations:

First, the terminal device periodically sends the first information to the network device.

Correspondingly, the network device periodically receives the first information from the terminal device; or,

Second, when the range of the uplink transmission power adjusted by the terminal device according to the first function exceeds a preset threshold, the terminal device records and sends the first information to the network device.

Correspondingly, the network device receives the first information from the terminal device.

Exemplarily, the preset threshold here may be 5dB, that is, when the terminal device adjusts the uplink transmission power for multiple times and the cumulative amplitude reaches 5dB, or when the single adjustment of the uplink transmission power is greater than or equal to 5dB, it needs to record and send to the network device The adjusted uplink transmission power range or the adjusted uplink transmission power.

Third, the network device sends a request message to the terminal device.

Correspondingly, the terminal device receives the request message from the network device. And, the terminal device sends the first information to the network device according to the request message.

Wherein, the request message is used to request to obtain the first information;

As an example but not a limitation, the network device sends the request information to the terminal device, and the request information may be sent periodically, or unicast or broadcast the request information. This application does not specifically limit it.

It should be noted that the above-mentioned several possible manners can be implemented individually or in combination.

Exemplarily, after receiving the request message from the network device, the terminal device may directly send the first information to the network device; or, the terminal device periodically sends the first information to the network device; or, the terminal device sends the first information to the network device based on the For the request message, the first information and the like need not be sent to the network device until the magnitude of the uplink transmission power adjusted according to the first function reaches a preset threshold. This application does not specifically limit it.

It should be understood that the above-mentioned several possible implementation modes are only exemplary illustrations and should not constitute any limitation to the solution of this application.

S430. The network device adjusts the configuration of the terminal device according to the first information.

Exemplarily, the network device may adjust the scheduling of uplink resources of the terminal device according to the first information, and/or the network device may adjust the configuration of the uplink beam of the terminal device according to the first information, and/or the network device may adjust the configuration of the terminal device's uplink beam according to the first information Physical channel resources, etc. This application does not specifically limit it.

Specifically, the adjustment of the network device to the terminal device configuration may be one or more of the following adjustment schemes, such as reducing the index value of the modulation and coding scheme (modulation and coding scheme, MCS), reducing the number of layers of uplink transmission, Configure a new downlink beam, and continue to use the uplink beam if it is not lower than the preset threshold.

According to the technical solution provided by this application, the terminal device sends the first information to the network device after enabling the first function and adjusting the uplink transmission power, so that the network device adjusts the terminal device according to the first information after receiving the first information. Configuration. This can further optimize uplink data transmission efficiency, wireless link connection quality, resource block (resource block, RB) allocation, etc. of the terminal device when the first function is enabled.

FIG. 5 is a schematic diagram of another example of the communication method applicable to the embodiment of the present application, and the specific implementation step 500 includes:

S510, the terminal device enables the first function.

Wherein, the first function is used to adjust the uplink transmission power according to the maximum allowable radiation amount MPE.

Further, enabling the first function may also be triggering, activating the first function, etc., which is not specifically limited in the present application.

It should be noted that the MPE needs to be obtained before the terminal device enables the first function. Moreover, after enabling the first function, the terminal device also needs to compare its own transmission power with the MPE, and then adjust the uplink transmission power according to the requirements of the MPE.

Exemplarily, the MPE may be predefined by the protocol, or the network device notifies the terminal device of the maximum allowable radiation that the cell can withstand, etc., which is not specifically limited in this application.

S520. The terminal device sends a first mobility report to the network device.

Correspondingly, the network device receives the first mobility report from the terminal device.

Wherein, the first mobility report includes MPE function enabling information.

Exemplarily, the terminal device adjusts uplink transmission power according to the first function; after adjusting the uplink transmission power, the terminal device detects a handover failure HOF or a radio link failure RLF, and records the first mobility report.

It should be noted that the MPE function activation information includes at least one of the following information: uplink transmission power when HOF or RLF is detected, uplink remaining transmission power, maximum uplink transmission power, whether the uplink transmission power has been adjusted according to MPE, according to The uplink transmission power value adjusted by the MPE, and the transmission power of the last successful uplink transmission before HOF or RLF.

In a possible implementation manner, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device. And, the terminal device enables the first function according to the indication information.

Wherein, the indication information may be 1 bit indication information used to instruct the terminal device to enable the first function, and/or the indication information is used to indicate a condition for enabling the first function.

In this embodiment of the present application, the condition for enabling the first function may include: the terminal device detects that there are people and/or objects in the theoretical danger zone NHZ.

Further, the enabling condition may also include that within the first period of time, the terminal device detects that there are always people and/or objects in the NHZ. Wherein, the first period of time may be 5 ms, etc., which is not specifically limited in the present application. That is, if the terminal device detects people and/or objects in the NHZ within 5 ms consecutively, then the terminal device needs to enable the first function, and adjust its own uplink transmission power according to the requirements of the MPE.

Specifically, the terminal device can generate a timer when detecting someone in the NHZ, and start to adjust the UL power according to the MPE requirement when the value of the timer exceeds 5 ms. If the end device detects that there is no person or object in the NHZ when the timer has not exceeded 5ms, the timer will be reset.

As an example but not a limitation, the network device sends the indication information to the terminal device, the indication information may be sent periodically, or the indication information may be unicast or broadcast. This application does not specifically limit it.

In another possible implementation manner, the terminal device sends capability information to the network device.

Correspondingly, the network device receives capability information from the terminal device. Moreover, in a case that the network device itself has an MPE-related function, it determines indication information for instructing the terminal device to enable the first function according to the capability information.

Wherein, the capability information is used to indicate that the terminal device supports the first function.

It should be noted that, indicating whether the terminal device supports the ability of the MPE to adjust the transmit power may be 1-bit indication information. The decision right of this 1 bit depends on the hardware condition of the terminal device, indicating whether the terminal device has this capability. For example, whether the terminal device has the ability to detect whether there is an obstruction in the NHZ, and whether it can determine whether the obstruction is a human body; if it cannot detect, it cannot determine whether there is a person in the NHZ, and thus cannot support MPE-related capabilities.

Optionally, the terminal device can report the capability information to the network device during initial access; during the handover process, the source network device can also send the MPE-related functions of the terminal device to the target network device, for example, in the handover request information (handover request message).

As an example but not a limitation, the sending and receiving of the first mobility report may include the following possible implementation manners:

First, the terminal device periodically sends the first mobility report to the network device.

Correspondingly, the network device periodically receives the first mobility report from the terminal device; or,

Second, when the range of the uplink transmission power adjusted by the terminal device according to the first function exceeds a preset threshold, the terminal device records and sends the first mobility report to the network device.

Correspondingly, the network device receives the first mobility report from the terminal device.

Exemplarily, the preset threshold here may be 5dB, that is, when the terminal device adjusts the uplink transmission power for multiple times and the cumulative amplitude reaches 5dB, or when the single adjustment of the uplink transmission power is greater than or equal to 5dB, it needs to record and send to the network device The adjusted uplink transmission power range or the adjusted uplink transmission power.

Third, the network device sends a request message to the terminal device.

Correspondingly, the terminal device receives the request message from the network device. And, the terminal device sends the first mobility report to the network device according to the request message.

Wherein, the request message is used to request to obtain the first mobility report;

As an example but not a limitation, the network device sends the request information to the terminal device, and the request information may be sent periodically, or unicast or broadcast the request information. This application does not specifically limit it.

It should be noted that the above-mentioned several possible manners can be implemented individually or in combination.

Exemplarily, after receiving the request message from the network device, the terminal device may directly send the first mobility report to the network device; or, the terminal device periodically sends the first mobility report to the network device; or, Based on the request message, the terminal device needs to wait until the range of the uplink transmission power adjusted according to the first function reaches a preset threshold before sending the first mobility report and the like to the network device. This application does not specifically limit it.

It should be understood that the above-mentioned several possible implementation modes are only exemplary illustrations and should not constitute any limitation to the solution of this application.

S530. The network device configures a first mobility parameter according to the first mobility report.

Wherein, the mobility parameter may include a threshold value (threshold value) for triggering handover, and the like.

Exemplarily, if the UE fails in HOF handover, the base station may consider that the handover failure is caused by the premature handover of the UE. Then, the base station will increase the handover threshold, which will increase the handover difficulty of the UE, which in turn will cause the handover time to be later. Details of the specific configuration of the mobility parameters may refer to the prior art, which is not specifically limited in the present application.

To sum up, through the implementation scheme provided above, the terminal device records the information of the MPE in the mobility report, which allows the network device to determine whether the HOF or RLF failure is due to the MPE after receiving the mobility report from the terminal device. cause; in this way, the network device can configure reasonable mobility parameters for the terminal device in a targeted manner.

6 is a schematic diagram of another example of the communication method applicable to the embodiment of the present application. The terminal device reports the MPE function activation information, so that the network device further optimizes and adjusts the uplink scheduling and resource allocation of the terminal device according to the MPE function activation information. The specific implementation step 600 includes:

S610, a terminal device (for example, UE) sends capability information to a network device (for example, a base station).

Correspondingly, the network device receives capability information from the terminal device.

Wherein, the capability information is used to indicate whether the terminal device supports the capability of adjusting transmission power according to the requirement of the MPE.

It should be understood that whether the terminal device supports the ability to adjust transmit power according to MPE requirements depends on the hardware conditions of the UE, such as whether the UE is capable of detecting whether there is an obstruction in the NHZ, and further, whether the UE can determine whether the obstruction is a human body. If the UE cannot detect it, it cannot judge whether there are people in the NHZ, and thus cannot support MPE-related capabilities.

As an example but not a limitation, whether the UE supports the ability to adjust transmit power according to the MPE requirement may be indicated by 1-bit indication information. Exemplarily, the UE may report the indication information to the base station during initial access; during the handover process, the source base station may also send the MPE-related functions of the UE to the target base station, for example, included in the handover request information (handover request message).

S620, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device.

Wherein, the indication information is used to indicate whether the UE enables MPE-related functions.

It should be noted that, after receiving the 1bit MPE-related capability reported by the UE, the base station should not only consider whether the UE supports the MPE-related function, but also consider whether itself has the MPE-related function. which is:

If the UE does not support MPE-related functions, regardless of whether the base station supports MPE-related functions, the base station may choose not to send indication information to the UE, or the base station may also issue an indication message that the UE does not enable MPE-related functions.

If the UE supports MPE-related functions, but the base station does not support MPE-related functions, the base station may send indication information to the UE to instruct the UE not to enable the MPE-related functions. Correspondingly, the UE will not enable the MPE function.

Optionally, the base station may not directly send the indication information to the UE, so that the UE will not enable the MPE-related function after not receiving the indication information.

If the UE supports MPE-related functions and the base station also supports MPE-related functions, the base station may send indication information to the UE to indicate whether the UE enables the MPE-related functions, and the indication information may be 1-bit indication information. If the indication information is used to indicate that the UE does not enable the MPE-related functions, then the UE does not enable the MPE-related functions; The UE decides whether to enable MPE-related functions by itself. If the UE decides to enable the MPE function, it can further determine whether the MPE activation condition is satisfied. If the MPE activation condition is met, the UE enables the MPE related functions. If the MPE activation condition is not met, the UE does not enable the MPE function.

Exemplarily, when the UE detects that there are people in the NHZ, the indication information can be used to instruct the UE to enable or disable MPE-related UL power adjustment immediately; optionally, the indication information can also be condition information: for example, condition information It may be a time T, which is used to indicate that when the UE detects someone in the NHZ, a timer is generated, and when the value of the timer exceeds T, the UL power is adjusted according to the MPE requirement. Wherein, if the UE detects that there is no one in the NHZ before the timer exceeds T, the timer will be reset.

Optionally, in step S620, when the base station instructs the UE to enable the MPE-related function, it may also add 1 bit of information to allow the UE to decide whether to enable the MPE-related function. In some cases, such as when the link condition is poor, or when the distance between the UE and the base station is relatively long, or when the UE transmits some signaling or data that needs to ensure high quality, the UE can choose not to enable MPE-related functions. Because after the UE enables MPE-related functions, it is likely to reduce the UL transmit power according to the requirements of the MPE, which may cause signaling or data transmission failures or handover failures in the above situations. If the base station instructs the UE not to enable the MPE-related functions, the additional 1-bit information can only be set to prevent the UE from deciding whether to enable the MPE-related functions.

As an example and not a limitation, when the UE is handed over from the source base station to the target base station, if both base stations have the same capabilities (both have the ability to indicate the UE's MPE switch, or both have the ability to indicate the UE's MPE switch), the target base station can keep The indication information of the source base station; if the source base station does not support the MPE related function of indicating the UE, and the target base station supports the MPE related function of indicating the UE, then the target base station can keep the indication information of the source base station, and can also decide the content of the indication information by itself; if If the source base station supports indicating the UE's MPE-related functions, but the target base station does not support indicating the UE's MPE-related functions, then the target base station can directly instruct the UE to disable the MPE-related functions.

S630. The terminal device enables an MPE-related function.

For example, according to the MPE requirements, the UE finds people or objects in the NHZ, and autonomously reduces the UL transmission power.

It should be understood that this step is performed under the assumption that both the base station and the UE have MPE-related functions, and the base station instructs the UE to enable the MPE-related functions.

Optionally, the UE has the ability to independently decide whether to enable the MPE function. When the UE decides to enable MPE-related functions and meets the conditions for MPE activation, this step can be realized, and then the UE UL power can be adjusted.

It should be noted that, when the UE receives the indication information from the base station, if the indication information indicates that the UE does not enable the MPE function, the UE will not enable it until it receives the indication information for enabling the MPE function next time.

S640. The terminal device sends the MPE function enabling information to the network device.

Correspondingly, the network device receives the MPE function activation information from the terminal device.

Exemplarily, if the UE enables the MPE function and performs UL power adjustment, such as reducing UL transmission power. Then the UE reports to the base station relevant information after adjusting the UL power according to the MPE requirements, which may include at least one of the following information:

(1) Affected UL beam information (if the UE behaves at the beam level);

(2) After the MPE function is enabled, the maximum transmission power of UE UL;

Among them, according to the current technology, indicating the UL beam information does not accurately indicate the ID of the uplink beam, and needs to be implicitly indicated through the DL/UL association relationship. For example, use the ID of the DL beam associated with the UL beam to indicate the UL beam.

It should be understood that the present application does not exclude subsequent possible implementation manners, for example, the UE may directly explicitly indicate the ID of the UL beam to the base station.

Exemplarily, due to the activities of people in the NHZ or the movement of the UE, the transmit power of the UE will also be adjusted according to the requirements of the MPE, so the UE needs to periodically report the relevant information after the MPE function is enabled; or the increase or decrease of the UE transmit power When a certain threshold is exceeded, the UE is triggered to record MPE-related function information, or to report based on a request message from the base station. The request message can be periodically sent to the UE by the base station in a broadcast or unicast manner.

S650, the network device optimizes resource configuration according to the MPE function enabling information.

Wherein, the optimal resource configuration here may be to adjust the UE's UL beam configuration, and/or change the UE's uplink scheduling, which depends on the affected UL beam information and/or in the MPE function activation information reported by the UE in step S630 above After the MPE function is enabled, the maximum transmission power of UE UL.

Exemplarily, for adjusting the uplink scheduling of the UE, the index value of the modulation and coding scheme (modulation and coding scheme, MCS) during the uplink can be reduced, so as to reduce the modulation order and ensure the correct transmission of the uplink data. The greater the value of the UL power adjusted according to the MPE requirements, the more the index value of the modulation and coding scheme MCS is reduced; if the UE UL supports space division multiplexing (SDM), the order of uplink transmission can also be reduced .

Exemplarily, for adjusting UL beam configuration, if the UE UL power is adjusted according to MPE requirements, so that the base station knows that a certain beam is affected, and when the transmit power of the beam is lower than a certain power threshold, the base station can configure a new downlink Beam beam, so as to avoid using the blocked UL beam, and resume its normal use until the next time the beam is no longer affected by the MPE.

Optionally, if the UE UL power is adjusted according to MPE requirements, so that the base station knows that a beam is affected, but the transmit power of the beam is not lower than a preset power threshold, the base station can choose to use the beam normally, or There is an option to reconfigure the new beam.

To sum up, through the implementation scheme provided above, the network device can know whether the UE has enabled the MPE function, as well as information related to the activation of the MPE function, and the network device can monitor the wireless links affected by the MPE according to the information related to the activation of the MPE function. Make optimization adjustments to improve the efficiency of the upward transmission.

7 is a schematic diagram of another example of the communication method applicable to the embodiment of the present application. The difference from the above method 600 is that the terminal device reports PH information, so that the network device further performs uplink scheduling and resource allocation of the terminal device according to the PH information. Optimization and tuning. For example, when a terminal device enables MPE-related functions, adjusting the UE UL power according to MPE requirements may affect the calculation of the PH value. The terminal device can report the impact, that is, update the calculation of the PH according to the influence of the MPE, and the network device Therefore, RB resources can be allocated to the terminal equipment more reasonably according to the updated PH value, so as to avoid allocating a large amount of resources to the terminal equipment affected by the MPE restriction. The specific implementation step 700 includes:

S710, a terminal device (for example, UE) sends capability information to a network device (for example, a base station).

Correspondingly, the network device receives capability information from the terminal device.

Wherein, the capability information is used to indicate whether the terminal device supports the capability of adjusting transmission power according to the requirement of the MPE.

It should be understood that whether the terminal device supports the ability to adjust transmit power according to MPE requirements depends on the hardware conditions of the UE, such as whether the UE is capable of detecting whether there is an obstruction in the NHZ, and further, whether the UE can determine whether the obstruction is a human body. If the UE cannot detect it, it cannot judge whether there are people in the NHZ, and thus cannot support MPE-related capabilities.

As an example but not a limitation, whether the UE supports the ability to adjust transmit power according to the MPE requirement may be indicated by 1-bit indication information. Exemplarily, the UE may report the indication information to the base station during initial access; during the handover process, the source base station may also send the MPE-related functions of the UE to the target base station, for example, included in the handover request information (handover request message).

S720, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device.

Wherein, the indication information is used to indicate whether the UE enables MPE-related functions.

It should be noted that, after receiving the 1bit MPE-related capabilities reported by the UE, the base station should not only consider whether the UE supports MPE-related functions, but also determine whether it has MPE-related functions. which is:

If the UE does not support MPE-related functions, regardless of whether the base station supports MPE-related functions, the base station may choose not to send indication information to the UE, or the base station may also issue an indication message that the UE does not enable MPE-related functions.

If the UE supports MPE-related functions, but the base station does not support MPE-related functions, the base station may send indication information to the UE to instruct the UE not to enable the MPE-related functions. Correspondingly, the UE will not enable the MPE function.

If the UE supports MPE-related functions and the base station also supports MPE-related functions, the base station may send indication information to the UE to indicate whether the UE enables the MPE-related functions, and the indication information may be 1-bit indication information. If the indication information is used to indicate that the UE does not enable the MPE-related functions, then the UE does not enable the MPE-related functions; The UE decides whether to enable MPE-related functions by itself. If the UE decides to enable the MPE function, it can further determine whether the MPE activation condition is satisfied. If the MPE activation condition is met, the UE enables the MPE related functions. If the MPE activation condition is not met, the UE does not enable the MPE function.

Exemplarily, when the UE detects that there are people in the NHZ, the indication information can be used to instruct the UE to enable or disable MPE-related UL power adjustment immediately; optionally, the indication information can also be condition information: for example, condition information It may be a time T, which is used to indicate that when the UE detects someone in the NHZ, a timer is generated, and when the value of the timer exceeds T, the UL power is adjusted according to the MPE requirement. Wherein, if the UE detects that there is no one in the NHZ before the timer exceeds T, the timer will be reset.

Optionally, in step S620, when the base station instructs the UE to enable the MPE-related function, it may also add 1 bit of information to allow the UE to decide whether to enable the MPE-related function. In some cases, such as when the link condition is poor, or when the distance between the UE and the base station is relatively long, or when the UE transmits some signaling or data that needs to ensure high quality, the UE can choose not to enable MPE-related functions. After the UE enables MPE-related functions, it is likely to reduce the UL transmit power according to the requirements of the MPE, which may cause signaling or data transmission failures or handover failures in the above situations. If the base station instructs the UE not to enable the MPE-related functions, the additional 1-bit information can only be set to prevent the UE from deciding whether to enable the MPE-related functions.

As an example and not a limitation, when the UE is handed over from the source base station to the target base station, if both base stations have the same capabilities (both have the ability to indicate the UE's MPE switch, or both have the ability to indicate the UE's MPE switch), the target base station can keep The indication information of the source base station; if the source base station does not support the MPE related function of indicating the UE, and the target base station supports the MPE related function of indicating the UE, then the target base station can keep the indication information of the source base station, and can also decide the content of the indication information by itself; if If the source base station supports indicating the UE's MPE-related functions, but the target base station does not support indicating the UE's MPE-related functions, then the target base station can directly instruct the UE to disable the MPE-related functions.

S730. The terminal device enables an MPE-related function.

For example, according to the MPE requirements, the UE finds people or objects in the NHZ, and autonomously reduces the UL transmission power.

It should be understood that this step is performed under the assumption that both the base station and the UE have MPE-related functions, and the base station instructs the UE to enable the MPE-related functions.

Optionally, the UE has the ability to independently decide whether to enable the MPE function. When the UE decides to enable MPE-related functions and meets the conditions for MPE activation, this step can be realized, and then the UE UL power can be adjusted.

It should be noted that, when the UE receives the indication information from the base station, if the indication information indicates that the UE does not enable the MPE function, the UE will not enable it until it receives the indication information for enabling the MPE function next time.

S740. When the terminal device adjusts UL power according to the MPE, record PH related information.

Wherein, the content recorded and reported by the UE may be the UL PH or the maximum transmit power of the UE, and such information may be used by the network device to update the calculation of the PH value of the UE.

It should be noted that the calculation of PH after the MPE function is turned on will be affected, and the calculation method of PH is changed from the original:

Power Headroom＝P _max -P _PUSCH

Among them, P _max is the maximum transmission power of the UE without being affected by MPE, and P _PUSCH is the transmission power of PUSCH, which is changed to:

Power Headroom _MPE =P _{max_MPE} -P _{PUSCH_MPE}

Wherein, P _{max_MPE} is the UE maximum transmission power after the MEP function is enabled, and P _{PUSCH_MPE} is the PUSCH transmission power affected by the MEP, and the transmission power is determined by the relative position of the UE and the human body.

In particular, if the calculation formula of PH is not updated in time, it will lead to errors in the calculation of PH value, namely:

Power Headroom＝P _{MAX_MPE} -P _{PUSCH_MPE}

FIG. 8 is a schematic diagram showing an example of PH value calculation before and after the UE adjusts the transmit power according to the MPE. As shown in FIG. 8 , before the UE adjusts the transmission power according to the MPE, Power Headroom=P _max -P _PUSCH ; after the UE adjusts the transmission power according to the MPE, the human body is not in the NHZ area. At this time, both P _max and P _PUSCH change due to the influence of the MPE. If the UE does not update and report the PH calculation method and PH value in time, the network device may allocate unreasonable resources to the UE.

It should be understood that since the relative position between the UE and the human body is constantly changing, it can be triggered periodically or by an event to measure and report the UL power headroom report PH of the UE or the maximum transmit power of the UE. For event-triggered situations, it can be triggered to measure and report the UL PH or the maximum transmit power of the UE only when the range of the UE’s power adjustment (increase or decrease) exceeds a certain threshold due to MPE.

For example, suppose the threshold for triggering measurement is 1dB, and the original maximum transmit power of UE UL is 15dB, but due to the impact of MPE, the maximum transmit power of UE UL drops to 13.5dB, then the measurement of UL PH and report.

Optionally, before allocating RB resources according to the ULPH reported by the UE, the network device may send a request message to the UE to request the UE to measure and report the current PH value, which may or may not be affected by the MPE influences. Then, the network device allocates RB resources according to the latest PH value.

S750. The terminal device sends PH related information to the network device.

Correspondingly, the network device receives PH-related information from the terminal device.

Exemplarily, the terminal device may report PH-related information affected by the MPE through a power headroom report (power headroom report, PHR).

S760, the network device optimizes resource allocation according to the pH value.

To sum up, through the implementation scheme provided above, when the UE enables the MPE-related functions, the UE can update the PH calculation method according to the MPE impact and report it, and the network device can allocate RBs to the UE more reasonably according to the updated PH value resources to avoid allocating large amounts of resources to UEs affected by MPE constraints.

9 is a schematic diagram of another example of the communication method applicable to the embodiment of the present application. The difference from the above methods 600 and 700 is that the UE records the MPE function activation information in the mobility report, and sends the mobility report to the network device, so that Network devices avoid configuring unreasonable mobility parameters. For example, when the UE enables MPE-related functions, if HOF or RLF caused by UL failure occurs, the UE can record MPE-related information in the mobility report, and the base station can know whether the HOF or RLF is due to MPE activation through the mobility report. Therefore, the mobility parameters can be accurately configured, and the occurrence of mobility parameter configuration errors can be reduced. The specific implementation step 900 includes:

S910, a terminal device (for example, UE) sends capability information to a network device (for example, a base station).

Correspondingly, the network device receives capability information from the terminal device.

Wherein, the capability information is used to indicate whether the terminal device supports the capability of adjusting transmission power according to the requirement of the MPE.

It should be understood that whether the terminal device supports the ability to adjust transmit power according to MPE requirements depends on the hardware conditions of the UE, such as whether the UE is capable of detecting whether there is an obstruction in the NHZ, and further, whether the UE can determine whether the obstruction is a human body. If the UE cannot detect it, it cannot judge whether there are people in the NHZ, and thus cannot support MPE-related capabilities.

As an example but not a limitation, whether the UE supports the ability to adjust transmit power according to the MPE requirement may be indicated by 1-bit indication information. Exemplarily, the UE may report the indication information to the base station during initial access; during the handover process, the source base station may also send the MPE-related functions of the UE to the target base station, for example, included in the handover request information (handover request message).

S920, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device.

Wherein, the indication information is used to indicate whether the UE enables MPE-related functions.

It should be noted that, after receiving the 1bit MPE-related capabilities reported by the UE, the base station should not only consider whether the UE supports MPE-related functions, but also determine whether it has MPE-related functions. which is:

If the UE does not support MPE-related functions, regardless of whether the base station supports MPE-related functions, the base station may choose not to send indication information to the UE, or the base station may also issue an indication message that the UE does not enable MPE-related functions.

If the UE supports MPE-related functions, but the base station does not support MPE-related functions, the base station may send indication information to the UE to instruct the UE not to enable MPE-related functions. Correspondingly, the UE will not enable the MPE function.

If the UE supports MPE-related functions and the base station also supports MPE-related functions, the base station may send indication information to the UE to indicate whether the UE enables the MPE-related functions, and the indication information may be 1-bit indication information. If the indication information is used to indicate that the UE does not enable the MPE-related functions, then the UE does not enable the MPE-related functions; The UE decides whether to enable MPE-related functions by itself. If the UE decides to enable the MPE function, it can further determine whether the MPE activation condition is satisfied. If the MPE activation condition is met, the UE enables the MPE related functions. If the MPE activation condition is not met, the UE does not enable the MPE function.

Exemplarily, when the UE detects that there are people in the NHZ, the indication information can be used to instruct the UE to enable or disable MPE-related UL power adjustment immediately; optionally, the indication information can also be condition information: for example, condition The information may be a time T, which is used to instruct the UE to generate a timer when detecting someone in the NHZ, and adjust the UL power according to the MPE requirement when the value of the timer exceeds T. Wherein, if the UE detects that there is no one in the NHZ before the timer exceeds T, the timer will be reset.

Optionally, in step S620, when the base station instructs the UE to enable the MPE-related function, it may also add 1 bit of information to allow the UE to decide whether to enable the MPE-related function. In some cases, such as when the link condition is poor, or when the distance between the UE and the base station is relatively long, or when the UE transmits some signaling or data that needs to ensure high quality, the UE can choose not to enable MPE-related functions. Because after the UE enables MPE-related functions, it is likely to reduce the UL transmit power according to the requirements of the MPE, which may cause signaling or data transmission failures or handover failures in the above situations. If the base station instructs the UE not to enable the MPE-related functions, the additional 1-bit information can only be set to prevent the UE from deciding whether to enable the MPE-related functions.

As an example and not a limitation, when the UE is handed over from the source base station to the target base station, if both base stations have the same capabilities (both have the ability to indicate the UE's MPE switch, or both have the ability to indicate the UE's MPE switch), the target base station can keep The indication information of the source base station; if the source base station does not support the MPE related function of indicating the UE, and the target base station supports the MPE related function of indicating the UE, then the target base station can keep the indication information of the source base station, and can also decide the content of the indication information by itself; if If the source base station supports indicating the UE's MPE-related functions, but the target base station does not support indicating the UE's MPE-related functions, then the target base station can directly instruct the UE to disable the MPE-related functions.

S930, the terminal device enables an MPE-related function.

For example, the UE detects people or objects in the NHZ, and autonomously reduces the UL transmission power according to the MPE requirements.

It should be understood that this step is performed under the assumption that both the base station and the UE have MPE-related functions, and the base station instructs the UE to enable the MPE-related functions.

Optionally, the UE has the ability to independently decide whether to enable the MPE function. When the UE decides to enable MPE-related functions and meets the conditions for MPE activation, this step can be realized, and then the UE UL power can be adjusted.

It should be noted that, when the UE receives the indication information from the base station, if the indication information indicates that the UE does not enable the MPE function, the UE will not enable it until it receives the indication information for enabling the MPE function next time.

S940, the terminal device detects RLF caused by handover failure HOF or UL failure.

Exemplarily, HOF and/or RLF exist because the UE reduces the uplink transmission power after enabling the MPE function. Then, the UE generates an RLF report and sends the RLF report to the network device.

It should be understood that the RLF caused by handover failure HOF or UL failure may be caused by reducing the UL transmit power because the UE needs to meet the MPE conditions; and/or HOF or RLF may also be caused by the poor link quality during uplink transmission at that time , this application does not specifically limit it.

S950. The terminal device records information about enabling the MPE function.

After the UE enables the MEP function, if it detects HOF or RLF caused by UL failure, the UE can record MPE information, including at least one of the following information:

(1) Whether the UE has adjusted the UL transmission power according to the MPE requirements;

(2) The UE adjusts the value of the UL transmit power due to the MPE; correspondingly, it can report the UE UL power headroom PH, or the maximum transmit power of the UE.

(3) UL transmit power when UE detects HOF/RLF;

(4) The transmit power of the UE when it succeeded in UL last time.

For example, if the MPE-related information indicates that the UE has not adjusted the UL transmission power according to the MPE, then the HOF or RLF this time has nothing to do with the MPE, and it may be caused by the movement of the UE or the human body, or the link quality at that time Poor results; if the MPE-related information records that the UE adjusted the UL transmit power according to the MPE, it is considered that the HOF or RLF may be related to the MPE, and the UE can choose to only record the UL power reduction value when it is adjusted by the MPE power. The greater the value of reducing the UL transmit power according to the MPE requirement, the higher the degree of correlation between HOF or RLF and MPE.

In the embodiment of the present application, the value of the UL transmit power reduction may be calculated in various manners, such as P _max -P _{MAX_MPE} . Optionally, the UE may take the value of the last successful UL transmission power of the UE as a reference, and record the UL transmission power when HOF/RLF is detected for comparison.

S960, the terminal device sends a mobility report to the network device.

Correspondingly, the network device receives the mobility report from the terminal device.

Wherein, the mobility report includes MPE related information.

For HOF or RLF failure, UE has countermeasures, such as performing cell reselection. When the UE and the base station can communicate normally, the UE will send a mobility report to the base station.

S970. The network device configures reasonable mobility parameters for the terminal device according to the mobility report.

Wherein, the mobility parameter may include a threshold value (threshold value) for triggering handover, and the like.

Exemplarily, if the UE fails in HOF handover, the base station may consider that the handover failure is caused by the premature handover of the UE. Then, the base station will increase the handover threshold, which will increase the handover difficulty of the UE, which in turn will cause the handover time to be later. Details of the specific configuration of the mobility parameters may refer to the prior art, which is not specifically limited in the present application.

To sum up, through the implementation scheme provided above, the terminal device records the information of the MPE in the mobility report, which allows the network device to determine whether the HOF or RLF failure is due to the MPE after receiving the mobility report from the terminal device. cause; in this way, the network device can configure reasonable mobility parameters for the terminal device in a targeted manner.

Figure 10 is a schematic diagram of another example of the method applicable to the embodiment of the present application. The difference from the above method 900 is that the terminal device does not record the mobility report related to the MPE, so that the network device can completely avoid configuring unreasonable mobility parameters . For example, when the UE activates the MPE function, the mobility problem caused by its HOF or RLF may be related to the MPE, and the UE does not directly record the mobility report during this period. Then, when the network device does not receive the mobility report, it can completely avoid configuring unreasonable mobility parameters because it does not know the information of the MPE. Of course, the network device will not know other factors that cause HOF or RLF, and will not configure reasonable mobility parameters, which will have a certain impact on UE transmission on the communication link. The specific implementation step 1000 includes:

S1010, a terminal device (for example, UE) sends capability information to a network device (for example, a base station).

Correspondingly, the network device receives capability information from the terminal device.

Wherein, the capability information is used to indicate whether the terminal device supports the capability of adjusting transmission power according to the requirement of the MPE.

It should be understood that whether the terminal device supports the ability to adjust transmit power according to MPE requirements depends on the hardware conditions of the UE, such as whether the UE is capable of detecting whether there is an obstruction in the NHZ, and further, whether the UE can determine whether the obstruction is a human body. If the UE cannot detect it, it cannot judge whether there are people in the NHZ, and thus cannot support MPE-related capabilities.

As an example but not a limitation, whether the UE supports the ability to adjust transmit power according to the MPE requirement may be indicated by 1-bit indication information. Exemplarily, the UE may report the indication information to the base station during initial access; during the handover process, the source base station may also send the MPE-related functions of the UE to the target base station, for example, included in the handover request information (handover request message).

S1020, the network device sends indication information to the terminal device.

Correspondingly, the terminal device receives the indication information from the network device.

Wherein, the indication information is used to indicate whether the UE enables MPE-related functions.

It should be noted that, after receiving the 1bit MPE-related capabilities reported by the UE, the base station should not only consider whether the UE supports MPE-related functions, but also determine whether it has MPE-related functions. which is:

If the UE does not support MPE-related functions, regardless of whether the base station supports MPE-related functions, the base station may choose not to send indication information to the UE, or the base station may also issue an indication message that the UE does not enable MPE-related functions.

If the UE supports MPE-related functions, but the base station does not support MPE-related functions, the base station may send indication information to the UE to instruct the UE not to enable the MPE-related functions. Correspondingly, the UE will not enable the MPE function.

If the UE supports MPE-related functions and the base station also supports MPE-related functions, the base station may send indication information to the UE to indicate whether the UE enables the MPE-related functions, and the indication information may be 1-bit indication information. If the indication information is used to indicate that the UE does not enable the MPE-related functions, then the UE does not enable the MPE-related functions; The UE decides whether to enable MPE-related functions by itself. If the UE decides to enable the MPE function, it can further determine whether the MPE activation condition is satisfied. If the MPE activation condition is met, the UE enables the MPE related functions. If the MPE activation condition is not met, the UE does not enable the MPE function.

Exemplarily, when the UE detects that there are people in the NHZ, the indication information can be used to instruct the UE to enable or disable MPE-related UL power adjustment immediately; optionally, the indication information can also be condition information: for example, condition The information may be a time T, which is used to instruct the UE to generate a timer when detecting someone in the NHZ, and adjust the UL power according to the MPE requirement when the value of the timer exceeds T. Wherein, if the UE detects that there is no one in the NHZ before the timer exceeds T, the timer will be reset.

Optionally, in step S620, when the base station instructs the UE to enable the MPE-related function, it may also add 1 bit of information to allow the UE to decide whether to enable the MPE-related function. In some cases, such as when the link condition is poor, or when the distance between the UE and the base station is relatively long, or when the UE transmits some signaling or data that needs to ensure high quality, the UE can choose not to enable MPE-related functions. Because after the UE enables MPE-related functions, it is likely to reduce the UL transmit power according to the requirements of the MPE, which may cause signaling or data transmission failures or handover failures in the above situations. If the base station instructs the UE not to enable the MPE-related functions, the additional 1-bit information can only be set to prevent the UE from deciding whether to enable the MPE-related functions.

As an example and not a limitation, when the UE is handed over from the source base station to the target base station, if both base stations have the same capabilities (both have the ability to indicate the UE's MPE switch, or both have the ability to indicate the UE's MPE switch), the target base station can keep The indication information of the source base station; if the source base station does not support the MPE related function of indicating the UE, and the target base station supports the MPE related function of indicating the UE, then the target base station can keep the indication information of the source base station, and can also decide the content of the indication information by itself; if If the source base station supports indicating the UE's MPE-related functions, but the target base station does not support indicating the UE's MPE-related functions, then the target base station can directly instruct the UE to disable the MPE-related functions.

S1030, the terminal device enables an MPE-related function.

For example, the UE detects people or objects in the NHZ, and autonomously reduces the UL transmission power according to the MPE requirements.

It should be understood that this step is performed under the assumption that both the base station and the UE have MPE-related functions, and the base station instructs the UE to enable the MPE-related functions.

Optionally, the UE has the ability to independently decide whether to enable the MPE function. When the UE decides to enable MPE-related functions and meets the conditions for MPE activation, this step can be realized, and then the UE UL power can be adjusted.

It should be noted that, when the UE receives the indication information from the base station, if the indication information indicates that the UE does not enable the MPE function, the UE will not enable it until it receives the indication information for enabling the MPE function next time.

S1040, the terminal device detects RLF caused by handover failure HOF or UL failure.

It should be understood that the RLF caused by handover failure HOF or UL failure may be caused by reducing the UL transmit power because the UE needs to meet the MPE conditions; and/or HOF or RLF may also be caused by the poor link quality during uplink transmission at that time .

Among them, for the RLF caused by the handover failure HOF or UL failure, the UE has countermeasures, such as performing cell reselection.

S1050, the terminal device does not record the mobility report.

When detecting the mobility problem caused by the UL problem, first judge whether the UE UL power drops due to the MPE. If not, it is considered that the mobility problem has nothing to do with the MPE, and the mobility report can be recorded. If If yes, the UE chooses not to record the mobility report. The cases where the UE does not record the corresponding mobility report include:

Exemplarily, after the UE enables the MEP function, if the mobility problem caused by the UL failure problem is detected, it can be judged first whether the UE UL transmit power has been adjusted according to the MPE requirements, thereby resulting in a decrease in the UE UL transmit power. If not, it is considered that the mobility problem is not related to the MPE, and the UE may record the mobility report; if yes, it is considered that the mobility problem is related to the MPE, and the UE may not record the mobility report.

Among them, the UE does not record the corresponding mobility report:

(1) For example, if the RLF caused by HOF/or UL failure is detected, the UE does not record the RLF report;

(2) For example, if a potential failure problem is detected, the successful HO report is not recorded;

(3) For example, if a mobility problem related to a secondary base station (second node, SN) is detected, the corresponding SN mobility report is not recorded.

Optionally, this embodiment of the present application may also choose not to judge whether the UL power of the UE is reduced due to the MPE, and the UE does not record all mobility reports during the period when the MPE is turned on. Then, it will never happen that the network device is configured with unreasonable mobility parameters.

It should be understood that since the mobility report is not recorded, the terminal device needs to communicate with the network device to detect whether the HOF/RLF problem still exists. The UE has a strategy to deal with HOF or RLF failure, such as cell reselection, etc., and the mobility report will not be sent until the UE and the base station can communicate normally.

To sum up, by directly not recording any MPE-related mobility report when the MPE is turned on, the network device will not be configured with unreasonable mobility parameters due to the MPE. However, if the occurrence of HOF or RLF is mainly caused by mobility problems or poor link quality, the influence of MPE accounts for a part of the reason, and the reasons for this part of MPE are also ignored in this implementation. Although it completely avoids the unreasonable configuration of mobility parameters by network equipment, it has a certain impact on the accurate transmission of UE UL.

In this application, in the above methods 400/500/600/700/900/1000, the mechanism for reporting MPE information by the UE, the mechanism for recording MPE information in the mobility report by the UE, and the mechanism for reporting PH information by the UE are respectively introduced , and introduce a mechanism that the UE does not record MPE-related mobility reports, so as to ensure that the UE can update the UE's UL configuration in time according to the MPE, or prevent the network device from incorrectly adjusting mobility parameters due to mobility problems caused by the MPE.
