The relevant knowledge of the technical solution of this application is described below:

Electromagnetic radiation specific absorption rate (Specific Absorption Rate, SAR) is an index parameter to measure the intensity of electromagnetic radiation from terminal equipment to the human body. It is applicable to the frequency spectrum below 6GHz. The standard has strict index requirements for the SAR value. The terminal equipment within a certain period of time The average cannot exceed this limit. Generally speaking, the higher the transmit power of the terminal, the higher the SAR value. Therefore, for high-power terminals (power>23dBm) compared with ordinary power terminals (power=23dBm), the SAR value is one of the key factors affecting its actual use.

The maximum permissible exposure (Maximum Permissible Exposure, MPE) is similar to SAR. It is also an index parameter to measure the electromagnetic radiation intensity of the terminal equipment to the human body. It is applicable to the spectrum above 6GHz and the millimeter wave spectrum. The standard has strict requirements for the MPE value. The average value of the transmit power density of the terminal equipment within a certain period of time cannot exceed this limit.

The technical problem to be solved of the application and the inventive concept of the application are described below:

As mentioned above, the current terminal device will consider the influence of electromagnetic wave radiation on the human body when determining Pcmax. For example, when the human body is close to the terminal device, the Pcmax determined by the terminal device will not consider the influence of electromagnetic wave radiation on the human body. A certain value is subtracted from the obtained Pcmax, but the relationship between this value and the influence of electromagnetic radiation on the human body is not accurate, resulting in the obtained Pcmax is not accurate enough. Based on this, the PHR reported by the terminal device is also not accurate. , which will cause the network device to be unable to accurately determine the next maximum schedulable transmit power to the terminal device.

In order to solve the above technical problems, in this application, the terminal device can determine the remaining available transmission power of the terminal device at the current time within the current transmission time window under the condition that the index parameters of the terminal device's electromagnetic wave radiation intensity to the human body are satisfied, according to the The remaining available transmit power reports information, so that the network device can determine the next maximum schedulable transmit power for the terminal device according to the information.

The technical scheme of the present application will be described in detail below:

Fig. 4 is an interactive flow chart of a wireless communication method provided by the embodiment of the present application. As shown in Fig. 4, the method may include:

S410: The terminal device determines the remaining available transmission power of the terminal device at the current moment within the current transmission time window when the index parameter of the terminal device's electromagnetic wave radiation intensity to the human body is satisfied;

S420: The terminal device reports the first information to the network device according to the remaining available transmit power;

S430: The network device determines the maximum schedulable transmit power of the network device to the terminal device at a next moment according to the first information.

It should be understood that the first information is used to determine the maximum schedulable transmit power of the network device to the terminal device at the next moment.

In some implementable manners, the index parameter of the electromagnetic wave radiation intensity of the terminal device to the human body may be SRA or MPE, but is not limited thereto.

It should be understood that, as mentioned above, the standard has strict index requirements for the SAR value, and the average value of the terminal equipment within a certain period of time cannot exceed this limit. Similarly, the standard has strict index requirements for the MPE value. The average value of the transmission power density of the equipment within a certain period of time cannot exceed this limit. However, SAR and MPE are actually related to the transmission power of the terminal equipment. The greater the transmission power of the terminal equipment, the higher the two indicators of the terminal equipment will be. The smaller the transmission power of the terminal equipment, the higher the two indicators of the terminal equipment will be. will be smaller. Based on this, if the terminal device wants to meet the requirements of the SAR and MPE indicators, it needs to determine the average transmit power within a transmit time window, and based on this, determine the remaining available transmit power of the terminal device at the current moment.

In some implementable manners, the terminal device has not yet performed data transmission at the current moment, but it is not limited thereto.

In some implementable manners, the above transmission time window may include: one or more time units, one time unit may be one or more time slots, of course, one time unit may also be one or more subframes, etc., the present application There is no restriction on the definition of the launch time window.

In some implementations, the current moment may be the current time slot, which belongs to the current transmission time window.

It should be understood that the next moment is the next moment of the current moment, for example, it may be the next time slot of the current time slot, and the next time slot may or may not belong to the current transmission time window. Applications are not limited to this.

It should be understood that, in this application, a time slot may also be referred to as a transmission time slot, which is not limited in this application.

It should be understood that the transmit power of a terminal device within a transmit time window may be constant, or may change with time, for example: Figure 5 is a schematic diagram of power changes of a terminal device provided in an embodiment of the present application , assuming that a transmission time window includes six different time slots T1-T6, as shown in Figure 5, the power of the terminal device in these six different time slots is not constant, and the average power of the terminal device in the transmission time window It is related to the transmit power of the terminal equipment on each time slot and the size of the transmit time window.

Exemplarily, FIG. 6 is a schematic diagram of a terminal device determining the remaining available transmission power when the SAR or MPE index is met according to the embodiment of the present application. Assume that the current transmission time window includes six different time slots T1-T6. The transmission powers of these six different time slots are P1, P2, P3, P4, P5, and P6 respectively. Assuming that the terminal equipment meets the SAR or MPE index, it needs the maximum average transmission power in the current transmission time window. The value is P0. When the current moment is T6, that is to say, after the terminal device has completed the power transmission from T1 to T5, the maximum available transmission power of the terminal device is not Pcmax but P6 when the terminal device meets the P0 limit. In the case of formula (1), the maximum value that x can take is:

P0*(T1+T2+T3+T4+T5+T6)-(P1*T1+P2*T2+P3*T3+P4*T4+P5*T5)≥x*T6 (1)

It should be understood that, in this example, P6 is the remaining available transmission power of the terminal device at the current moment within the current transmission time window of the terminal device.

In some implementation manners, the first information is any of the following, but not limited thereto:

first indication information, where the first indication information is used to indicate that the remaining available transmit power is lower than a first preset power threshold;

second indication information, where the second indication information is used to indicate that the relative power of the remaining available transmit power relative to the reference power is higher than a second preset power threshold;

A first value corresponding to the remaining available transmit power;

A second value corresponding to the first transmit power headroom, where the first transmit power headroom is the transmit power headroom between the remaining available transmit power and the transmit power that the network device schedules the terminal device at the current moment;

The third value corresponding to the second transmission power headroom, the second transmission power headroom is the minimum value of the remaining available transmission power and the configurable maximum transmission power of the terminal device, and the network device schedules the transmission of the terminal device at the current moment Power headroom for transmit power.

In some practicable manners, the reporting manner of the first information is any of the following, but not limited thereto: a periodic reporting manner, a semi-continuous reporting manner, and an event-triggered reporting manner.

In some implementation manners, when the first information is reported in a periodic manner, the reporting period of the first information may be configured or predefined by the network device for the terminal device, which is not limited in this application.

In some realizable manners, when the reporting method of the first information is a semi-continuous reporting method, the network device can configure the reporting period of the first information for the terminal device, but the trigger signaling of the network device needs to be used to control the first information. Start reporting or stop reporting. Wherein, the trigger signaling may be any of the following, but not limited to: Radio Resource Control (Radio Resource Control, RRC) signaling, Media Access Control Control Element (Medium Access Control Control Element, MAC CE), downlink Control information (Downlink control information, DCI).

In some practicable manners, when the reporting method of the first information is an event-triggered reporting method, the event that triggers the reporting of the first information may be at least one of the following events, but is not limited thereto: the remaining available transmit power is lower than the first preset Set a power threshold; the remaining available transmit power is higher than the second preset power threshold relative to the reference power; the first transmit power headroom is lower than the preset power headroom threshold; the second transmit power headroom is lower than the preset power headroom threshold ; The terminal device receives an activation report instruction sent by the network device, the activation report instruction is used to activate the terminal device to report the first information, wherein the activation report instruction can be any of the following, but not limited to this: RRC signaling, MAC CE, DCI.

In some practicable manners, the network device may control a timer to set a preset time period, and if the current time is within the preset time period, the terminal device reports the first information to the network device according to the remaining available transmit power, On the contrary, if the current time is not within the preset time period, the terminal device does not report the first information to the network device. Or, if the current time is not within the preset time period, the terminal device reports the first information to the network device according to the remaining available transmit power; on the contrary, if the current time is within the preset time period, the terminal device does not report the first information to the network device. a message.

In some implementable manners, the first information is carried in any of the following, but not limited thereto: RRC signaling, MAC signaling, and physical layer signaling. Wherein, the MAC signaling may be MAC CE, and the physical layer signaling may be DCI.

In some implementable manners, the first information is carried in the PHR. For example: FIG. 7 is a schematic diagram of carrying the first information in the PHR. As shown in FIG. 7 , the first information may be carried by adding a new field in the PHR or using existing idle bits.

It should be noted that the above-mentioned first information may be based on a single frequency band or each frequency band in a combined frequency band composed of multiple frequency bands, or based on a combined frequency band composed of multiple frequency bands. The reporting of the first information in terms of a single frequency band is explained:

Embodiment 1, for the case of a single frequency band, when the remaining available transmission power of the terminal device on the single frequency band is lower than the first preset power threshold, it can send the first indication information to the network device to indicate the single frequency band The remaining available transmit power is lower than a first preset power threshold. Wherein, the remaining available transmit power being lower than the first preset power threshold includes the situation that the remaining available transmit power is zero.

In some implementable manners, the first preset power threshold is configured or predefined by the network device for the terminal device, but is not limited thereto.

In some implementable manners, the network device may configure the first preset power threshold to the terminal device through RRC signaling or other available signaling.

In some implementable manners, there are one or more first preset power thresholds.

In some implementable manners, the first preset power threshold is an absolute power threshold.

In some implementable manners, the value of the absolute power threshold may be 5dBm or 10dBm, etc., and the present application does not limit the specific value of the absolute power threshold.

Example 1, assuming that there is an absolute power threshold of 5dBm, when the remaining available transmit power of the terminal equipment on a single frequency band is 4dBm, which is lower than 5dBm, the terminal equipment reports the first indication information to the network equipment to indicate that the terminal equipment is in a certain frequency band. The remaining available transmit power on a single frequency band is less than 5dBm.

Example 2, assuming that there are two absolute power thresholds of 5dBm and 10dBm, when the remaining available transmit power of the terminal device on a single frequency band is 4dBm, which is lower than 5dBm, the terminal device reports the first indication information to the network device to instruct the terminal The remaining available transmit power of the device on a single frequency band is lower than 5dBm. When the remaining available transmission power of the terminal equipment on a single frequency band is 9dBm, which is lower than 10dBm, the terminal equipment reports the first indication information to the network equipment to indicate that the remaining available transmission power of the terminal equipment on a certain single frequency band is lower than 10dBm .

Embodiment 2, for the case of a single frequency band, when the relative power of the remaining available transmission power of the terminal device on the single frequency band relative to the reference power is higher than the second preset power threshold, it can send the second indication information to the network device, to indicate that the remaining available transmit power on the single frequency band is higher than the second preset power threshold relative to the reference power.

In some implementable manners, the second preset power threshold is configured or predefined by the network device for the terminal device, but is not limited thereto.

In some implementable manners, the network device may configure the second preset power threshold to the terminal device through RRC signaling or other available signaling.

In some implementable manners, there are one or more second preset power thresholds.

In some implementable manners, the second preset power threshold is a relative power threshold relative to the aforementioned reference power.

In some implementable manners, the value of the relative power threshold may be 5dBm or 10dBm, etc., and the present application does not limit the specific value of the relative power threshold.

In some implementation manners, the reference power is a configurable maximum transmit power of the terminal device, that is, Pcmax, or another fixed transmit power, but is not limited thereto. For example: Figure 8 is a schematic diagram of a relative power threshold provided by the embodiment of the present application, and Figure 9 is a schematic diagram of multiple relative power thresholds provided by the embodiment of the present application, as shown in Figure 8 and Figure 9, where the reference power is the terminal The configurable maximum transmit power of the device, that is, Pcmax, and the PAL in Figure 8 and Figure 9 are the remaining available transmit power (Power Available Left, PAL).

Example 3, assuming that there is a relative power threshold of 5dBm, when the relative power of the remaining available transmit power of the terminal device on a single frequency band relative to the reference power is 6dBm, which is higher than 5dBm, the terminal device reports the second indication information to the network device , to indicate that the relative power of the remaining available transmit power of the terminal device on the single frequency band relative to the reference power is higher than 5dBm.

Example 4, assuming that there are two relative power thresholds 5dBm and 10dBm, when the relative power of the remaining available transmit power of the terminal equipment on a single frequency band relative to the reference power is 6dBm, which is higher than 5dBm, the terminal equipment reports the first Two indication information, to indicate that the relative power of the remaining available transmission power of the terminal equipment on the single frequency band relative to the reference power is higher than 5dBm. When the relative power of the remaining available transmit power of the terminal device on a single frequency band relative to the reference power is 11dBm, which is higher than 10dBm, the terminal device reports the second indication information to the network device to indicate the terminal device on the single frequency band. The relative power of the remaining available transmit power with respect to the reference power is higher than 10 dBm.

Embodiment 3, for the case of a single frequency band, the terminal device may report the first value corresponding to the remaining available transmission power on the single frequency band to the network device.

In some implementable manners, the first value is determined according to a correspondence between the remaining available transmit power range to which the remaining available transmit power belongs and the first value. That is to say, a one-to-one correspondence between multiple remaining available transmit power intervals and reported values may be set, for example, as shown in Table 1:

Table 1

Among them, a, b, c, x, and y are all real numbers greater than or equal to 0.

Further, after the network device obtains the first value, it may determine the remaining available transmit power interval according to the one-to-one correspondence between the multiple remaining available transmit power intervals and the reported value shown in Table 1 and the first value, based on this , to determine the maximum schedulable transmit power of the network device to the terminal device at the next moment.

Example 5, assuming that the remaining available transmit power interval determined by the terminal device belongs to b > PAL ≥ a, then the terminal device can select a value between the multiple remaining available transmit power intervals shown in Table 1 and the reported value. A corresponding relationship determines that the reported value corresponding to the interval is PAL_1, and based on this, the terminal device may report the PAL_1 to the network device.

It should be noted that the first value corresponding to the remaining available transmit power may also be the remaining available transmit power itself, which is not limited in this application.

Based on this, the terminal device can report the PALR_1 to the network device.

It should be noted that the second value corresponding to the first transmit power headroom may be the first transmit power headroom itself, and the third value corresponding to the second transmit power headroom may be the second transmit power headroom itself. This is not limited.

The following describes the reporting of the first information based on the combined frequency band or each frequency band in the combined frequency band:

It should be understood that the transmission power of a terminal device within a transmission time window may change with time. For the combined frequency band, even in the same time slot, the transmission power of the terminal device on each frequency band on the time slot The power can be different, for example: Figure 11 is a schematic diagram of the power change of the terminal equipment provided in the embodiment of the present application, assuming that a transmission time window includes three different time slots T1-T3, as shown in Figure 11, the terminal equipment in different time slots The transmit power is not constant, and the average power of the terminal device in the transmit time window is affected by the transmit power on each time slot and the size of the window, where the transmit power on each time slot includes cc1 and cc2 transmit power.

Embodiment 5, the above-mentioned combined frequency band can be regarded as a frequency band, for example: as shown in Figure 12, the transmit power of cc1 and cc2 on the T1 time slot can be regarded as the total transmit power on a frequency band formed by cc1 and cc2, That is, P1, the transmission power of cc1 and cc2 on the T2 time slot can be regarded as the total transmission power on a frequency band composed of cc1 and cc2, which is P2, and the transmission power of cc1 and cc2 on the T3 time slot can be seen as The total transmit power on a frequency band formed by cc1 and cc2 is P3.

Assuming that the total configurable maximum transmit power of the terminal device on the combined frequency band is recorded as Pcmax_CA, the total remaining available transmit power of the terminal device on the combined frequency band is recorded as PAL_CA, and the terminal scheduled by the network device on the combined frequency band The total transmit power of the device is recorded as TxPow_CA, and the total transmit power headroom of the terminal device in the combined frequency band is recorded as PALR_CA, then PALR_CA=PAL_CA-TxPow_CA or min{PAL_CA,Pcmax_CA}-TxPow_CA. Based on this, the terminal device can report any of the following items to the network device:

First indication information, where the first indication information is used to indicate that the PAL_CA is lower than a first preset power threshold, where the first preset power threshold is a preset power threshold for the combined frequency band as a whole;

The value corresponding to PAL_CA;

The value corresponding to PALR_CA.

It should be noted that since the above-mentioned combined frequency band can be regarded as a frequency band, the reporting method of the first information on the combined frequency band can refer to the above-mentioned reporting method for the first information on a single frequency band, and this application does not discuss this. Let me repeat.

Embodiment 6, for the configurable maximum transmit power of the terminal device, the remaining available transmit power of the terminal device, the first preset power threshold, and the second preset power threshold, the combined frequency band can be regarded as a frequency band, that is, these The values are all the total quantity values on the combined frequency band, but for the transmission power of the network equipment to schedule the terminal equipment, the combined frequency band can be viewed separately, that is, the transmission power of the network equipment to schedule the terminal equipment includes: network equipment in the combined frequency band The transmit power of the terminal equipment is scheduled on the frequency band. For example: the combined frequency band is composed of cc1 and cc2, then the network device scheduling the transmit power of the terminal device includes: the network device schedules the transmit power of the terminal device on cc1, and the network device schedules the transmit power of the terminal device on cc2. Based on this, the network device can determine the transmit power headroom on cc1 and cc2.

Assuming that the total configurable maximum transmit power of the terminal device on the combined frequency band is recorded as Pcmax_CA, the total remaining available transmit power of the terminal device on the combined frequency band is recorded as PAL_CA, and the terminal device scheduled by the network device on frequency band i The transmit power of the combined frequency band is recorded as TxPow_i, and the transmit power margin of the terminal equipment on the frequency band i in the combined frequency band is recorded as PALR_i, i=1～N, and N is the number of frequency bands included in the combined frequency band, then PALR_i=PAL_CA–TxPow_i or min {PAL_i, Pcmax_CA}-TxPow_i. Based on this, the terminal device can report at least one of the following items to the network device:

The value corresponding to PAL_CA;

The value corresponding to PALR_i, i=1～N, N is the number of frequency bands included in the combined frequency band.

Example 7, as shown in Figure 13, assuming that the total configurable maximum transmit power of the terminal device on the combined frequency band is marked as Pcmax_CA, and the total remaining available transmit power of the terminal device on the combined frequency band is marked as PAL_CA, the network The transmit power of the terminal device scheduled by the device on the cc1 is recorded as TxPow1, and the transmit power of the terminal device scheduled by the network device on the cc1 is recorded as TxPow2, then the transmit power margin of the terminal device under cc1 is recorded as PALR1, then PALR1 =PAL_CA-TxPow1 or min{PAL_CA, Pcmax_CA}-TxPow1, the transmit power headroom of the terminal equipment under cc2 is recorded as PALR2, then PALR2=PAL_CA-TxPow2 or min{PAL_CA, Pcmax_CA}-TxPow2.

It should be noted that, for the reporting method of the first information on the combined frequency band, reference may be made to the above-mentioned reporting method for the first information on the single frequency band, which will not be repeated in this application.

Assuming that the configurable maximum transmission power of the terminal device on the frequency band i in the combined frequency band is denoted as Pcmax_i, the remaining available transmit power of the terminal device on the frequency band i is denoted as PAL_i, and the terminal scheduled by the network device on the frequency band i The transmit power of the device is recorded as TxPow_i, and the transmit power headroom of the terminal device in the frequency band i is recorded as PALR_i, then PALR_i=PAL_i–TxPow_i or min{PAL_i,Pcmax_i}-TxPow_i, where i=1～N, N is The number of frequency bands included in the combined frequency band. Based on this, the terminal device can report any of the following items to the network device for the frequency band i:

First indication information, where the first indication information is used to indicate that the PAL_i is lower than a first preset power threshold, where the first preset power threshold is a preset power threshold for the frequency band i;

The second indication information, the second indication information is used to indicate that the relative power of PAL_i relative to the reference power, such as Pcmax_i, is higher than a second preset power threshold, where the second preset power threshold is for the frequency band i preset power threshold;

The value corresponding to PAL_i;

In some implementable manners, the corresponding first preset power thresholds on each frequency band in the combined frequency bands may be the same or different.

In some implementable manners, the corresponding second preset power thresholds on each frequency band in the combined frequency bands may be the same or different.

It should be noted that, for different frequency bands in the combined frequency band, the first information reported by the terminal device may be of the same or different types, for example: assuming that the combined frequency band includes two frequency bands cc1 and cc2, then the terminal device may report to the network device about cc1 The first indication information reports the value corresponding to PAL_2 about cc2. For another example, assuming that the combined frequency band includes two frequency bands cc1 and cc2, the terminal device may report PALR_1 about cc1 and report PALR_2 about cc2 to the network device.

The first preset power threshold is also for cc1 and cc2 respectively, and the second preset power threshold is also for cc1 and cc2 respectively.

Embodiment 8, when the first information is for the combined frequency band, when the remaining available transmit power exceeds the total transmit power of the network device scheduling the terminal equipment on the combined frequency band, send data to the combined frequency band according to the priority of each frequency band in the combined frequency band The transmit power is allocated for each frequency band.

In some implementation manners, the priority of each frequency band may be configured by the network device, or may be predefined, which is not limited in this application.

Example 9, assuming that the combined frequency band includes cc1 and cc2, assuming that the priority of cc1 is higher than that of cc2, and assuming that the remaining available transmission power of the current terminal device on this combined frequency band exceeds the total transmission of terminal devices scheduled by the network device on the combined frequency band power, then the terminal device can preferentially allocate transmit power to cc1.
