Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the prior art, SAR is an average measurement value of terminal equipment in a period of time, and is an index parameter for measuring the intensity of electromagnetic radiation of a terminal to a human body in a frequency band below 6 GHz. In order to avoid the harm of electromagnetic radiation of the terminal equipment to human bodies, strict index requirements are required on SAR values of the radiation of the terminal equipment in the standard, and the terminal cannot exceed the limit value. MPE is an average measurement value of power density of a terminal in a certain area within a period of time, and is an index parameter for measuring the intensity of electromagnetic radiation of the terminal to a human body in a frequency band above 6 GHz. In order to avoid the harm of electromagnetic radiation of the terminal equipment to human bodies, strict index requirements are imposed on the MPE value of the radiation of the terminal equipment in the standard, and the terminal cannot exceed the limit value.
In order to meet SAR and MPE standards, maximum uplink slot ratio (maxULdutycycle) capability is typically introduced from the standpoint of reducing the radiation time of the terminal device. The terminal equipment reports the maximum uplink duty ratio which can be supported by the base station when the base station meets SAR or MPE in a certain frequency band, and after the uplink time slot duty ratio scheduled by the base station exceeds the capacity, the terminal equipment adopts a power back-off mode to meet SAR and MPE standards.
However, when the transmission power of the terminal device is too high in the initial time in a certain period of time, the transmission power of the terminal device is possibly limited in a power back-off mode, so that the problem that the communication between the terminal device and the network device cannot meet the real-time or high-power service requirement due to failure of a link caused by incapacity of transmitting power or incapacity of transmitting high-power signals in a later time to meet SAR and MPE standards is caused.
In order to solve the above problems, the embodiments of the present application provide a communication method and apparatus, which adjust the transmitting power of a terminal device in time by sending a remaining value of radiation capability to a network device by the terminal device, so as to avoid the problem that the terminal device cannot transmit power or cannot transmit a high-power signal to cause a link failure in order to meet SAR and MPE standards.

As shown in fig. 1, communication is performed between a terminal device 101 and a network device 102. In order to meet the SAR and MPE standards, when the transmission power of the terminal device 101 is continuously too high and exceeds the capability threshold, the network device 102 sends information to the terminal device 101, and controls the terminal device 101 to adjust the transmission power and the transmission time so as to meet the SAR and MPE standards and avoid injury to human body.
The number of terminal devices 101 and network devices 102 included in the communication system is not limited in the embodiment of the present application.
The Terminal device 101 may also be called a Terminal (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like.

It should be noted that, the communication method according to the embodiments of the present application may be applied to a communication system, and the application implementation does not limit the applicable communication system, and may be a New Radio (NR) communication system, or may be another communication system.
It should be noted that, the adjustment of the transmission power of the terminal device is only one application scenario of the present application, and the communication method provided in the embodiment of the present application may be applied to any scenario where the network device needs to determine the transmission energy residual value of the wireless signal.
The following takes a terminal device and a network device as examples, and specific embodiments are used to describe the technical solutions of the embodiments of the present application in detail. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a signaling interaction diagram of a communication method according to an embodiment of the present application. This embodiment relates to how to adjust the transmit power of the terminal device. As shown in fig. 2, the method includes:
s201, the terminal equipment determines a transmission energy residual value of the wireless signal in a first time period.
Wherein the transmission energy residual value is related to the transmission power and the transmission time of the terminal device.
To meet SAR and MPE standards, the terminal equipment typically needs to define the total transmit energy for a period of time. Illustratively, millimeter wave terminal devices, in order to meet MPE requirements, need to meet average power densities of no more than 10w/m in a matter of seconds 2 Requirements of/s. Based on SAR and MPE standards, the transmit energy value over a period of time is essentially defined, and is the cumulative value of the terminal device transmit power times time. Therefore, the transmission energy residual value of the wireless signal in a period of time can limit the available transmission power of the terminal equipment in unit time and unit area.
Fig. 3 is a schematic diagram of a transmit energy limitation of a terminal device according to an embodiment of the present application. As shown in fig. 3, the transmit power of the terminal device is kept relatively low during the period of the first W, but it is ensured that the terminal device can transmit signals during the entire period of the first W. In the second W period, the transmission power of the terminal device in the initial stage is too high, which results in that the terminal device does not have enough power or cannot transmit signals in the latter part of the second W period. Based on this, in the case where the transmission energy remainder is determined, the larger the transmission power is, the shorter the transmission time is; accordingly, the smaller the transmission power, the longer the transmission time.
In this step, the transmission energy residual value of the wireless signal in the first time period by the terminal device may be a complete energy value in the first time period detected at the starting time of the first time period, or may be a transmission energy residual value between the first time detected at any one of the first time periods and the technical time of the first time period, or may be a transmission energy residual value between certain time sub-periods in the first time period.
The embodiment of the application does not limit how to determine the transmission energy residual value of the wireless signal of the terminal device in the first time period. In an exemplary embodiment, the terminal device may first determine a total transmit energy value for the entire first period based on SAR and MPE criteria, then determine a used transmit energy value according to the transmit power that has been used by the terminal device, and finally subtract the used transmit energy value from the total transmit energy value to obtain a transmit energy remainder for the entire first period.
S202, the terminal equipment sends the transmission energy residual value of the wireless signal to the network equipment.
In this step, after the terminal device determines the transmission energy residual value of the wireless signal in the first period, the terminal device sends the transmission energy residual value of the wireless signal to the network device.
The application does not limit when to send the transmission energy residual value of the wireless signal to the network device, and in some embodiments, the terminal device sends the transmission energy residual value of the wireless signal to the network device after determining the transmission energy residual value of the wireless signal each time; in other implementations, the terminal device may send the transmit energy residual value of the wireless signal to the network device only if it is determined that the transmit energy residual value of the wireless signal is less than the energy threshold.
In addition, the terminal device may further preset a reporting time of the transmission energy residual value of the wireless signal. For example, the terminal device may be preset to report the transmission energy remainder at the beginning time of the first period; or, the transmission energy residual value in the first time period can be used as the static terminal capability to be reported to the network equipment when the terminal equipment is initially accessed to the network; alternatively, the terminal device may report the transmit energy residual value at any time within the first period.
In an exemplary embodiment, after the terminal device sends the transmission energy residual value to the network device, in consideration of the space transmission delay from the terminal device to the network device, the timing of the first time period can be started after the terminal device reports, so that the terminal and the network are ensured to be in the same time period for energy statistics.
According to the communication method provided by the embodiment of the application, the terminal equipment determines the transmission energy residual value of the wireless signal of the terminal equipment in the first time period, the transmission energy residual value is related to the transmission power and the transmission time of the terminal equipment, and the transmission energy residual value of the wireless signal is sent to the network equipment. The terminal equipment can send the transmission energy residual value of the wireless signal in a period of time to the network equipment, the network equipment determines the limit value of the transmission energy caused by SAR or MPE for the terminal equipment in a period of time, and then the transmission power and the transmission time of the terminal equipment can be adjusted in time, so that the condition that the terminal equipment fails to transmit power and then causes link failure is avoided for meeting SAR and MPE standards.
It should be noted that, the transmission energy residual value of the wireless signal sent by the terminal device to the network device may be used for multiple purposes, and the adjustment of the transmission power and/or the transmission time of the terminal device based on the transmission energy residual value is only one of the realizations. The adjustment of the transmission power and/or the transmission time of the terminal device based on the transmission energy remainder of the radio signal will be described below. Fig. 4 is a signaling interaction diagram of another communication method according to an embodiment of the present application. As shown in fig. 4, on the basis of the above embodiment, the communication method includes:
s301, the terminal equipment determines a transmission energy residual value of a wireless signal of the terminal equipment in a first time period.
Wherein the transmission energy residual value is related to the transmission power and the transmission time of the terminal device.
S302, the terminal equipment sends the transmission energy residual value of the wireless signal to the network equipment.
The technical terms, effects, features, and exemplary embodiments of S301 to S302 can be understood with reference to S201 to S202 shown in fig. 2, and will not be described again here for repeated contents.
S303, the network equipment determines the adjustment quantity of the transmitting power and/or the transmitting time of the terminal equipment according to the transmitting energy residual value of the wireless signal transmitted by the terminal equipment.
In this step, when the network device receives the transmission energy residual value of the wireless signal sent by the terminal device, the total energy schedulable in the first time period can be determined. Based on this, the adjustment amount of the transmission power and/or the transmission time of the terminal device can be determined according to the communication service requirement of the terminal device.
For example, when the real-time requirement of the communication service is not high and the instantaneous rate requirement is high, the transmission power of the terminal device can be increased, and accordingly, the available transmission time of the terminal device in the first period of time can be reduced correspondingly, and at this time, the adjustment amount of the transmission power of the terminal device is positive and the adjustment amount of the transmission time is negative.
For example, when the communication service has a high requirement on real-time performance and a low requirement on instantaneous rate, and the continuity of the service needs to be ensured, the transmission power of the terminal device can be reduced, and correspondingly, the available transmission time of the terminal device in the first period of time can be correspondingly increased, at this time, the adjustment amount of the transmission power of the terminal device is negative, and the adjustment amount of the transmission time of the terminal device is positive.
In addition, if the current transmitting power of the terminal device matches with the current communication service requirement, the transmitting power of the terminal device may not be adjusted, and at this time, the adjusting amount of the transmitting power and the transmitting time of the terminal device is zero.
In some embodiments, a mapping relationship between a transmission energy residual value and an adjustment amount of transmission power and/or transmission time may be pre-established, so as to find a corresponding power adjustment value based on a received transmission energy residual value. In other embodiments, the algorithm model may be trained based on historical transmit energy residuals and adjustments to historical transmit power and/or transmit time, and after the transmit energy residuals are received, the transmit energy residuals may be input into the algorithm model and adjustments to the output transmit power and/or transmit time may be obtained.
And S304, the network equipment sends first information to the terminal equipment according to the adjustment amount of the transmitting power and/or the transmitting time of the terminal equipment, wherein the first information is used for indicating the terminal equipment to adjust the transmitting power and/or the transmitting time in a first time period.
The first information includes transmission power control information and/or uplink transmission time scheduling information.
In this step, after the network device determines the adjustment amount of the transmission power of the terminal device, first information may be sent to the terminal device, to instruct the terminal device to adjust the transmission power and/or the transmission time, where the first information may be closed-loop transmission power control information, and is used to directly increase or decrease the transmission power and/or the transmission time of the terminal.
S305, the terminal equipment adjusts the transmitting power and/or the transmitting time according to the first information.
In this step, after the terminal device receives the first information, power control may be performed according to a terminal device power control mechanism.
In some embodiments, power control may be achieved by the following transmit power control equation:
wherein P is O_PUSCHb,f,c, (j) The cell-level open-loop reference transmit power broadcast for the network device, which value is typically unchanged;the number of resource blocks allocated to the network device to the terminal device, < >>The method can be used for controlling the transmitting power of the network equipment to the terminal equipment; alpha b,f,c (j) Is the space propagation loss PL b,f,c (q d ) Is a weight of (2);as a power control parameter related to a modulation and coding scheme, it is generally applicable to adapt to different modulation schemes.
In addition, in the case of the optical fiber,then it is closed loop power control information for directly increasing or decreasing the transmit power and/or transmit time of the terminal.
In this step, the first information may be closed loop power control information, and the closed loop power control information determined based on the adjustment amount of the transmission power and/or the transmission time may directly increase or decrease the transmission power and/or the transmission time of the terminal.
According to the communication method provided by the embodiment of the application, the terminal equipment determines the transmission energy residual value of the wireless signal of the terminal equipment in the first time period, the transmission energy residual value is related to the transmission power and the transmission time of the terminal equipment, and the transmission energy residual value of the wireless signal is sent to the network equipment. And the network equipment determines the adjustment quantity of the transmitting power and/or the transmitting time of the terminal equipment according to the transmitting energy residual value of the wireless signal transmitted by the terminal equipment. And the network equipment sends the first information to the terminal equipment according to the adjustment amount of the transmitting power and/or the transmitting time of the terminal equipment, so that the terminal equipment adjusts the transmitting power and/or the transmitting time according to the first information. In this way, the network device adjusts the transmitting power and/or transmitting time of the terminal device based on the transmitting energy residual value, so that the transmitting power and transmitting time of the terminal device are estimated more accurately, and the network is given enough scheduling flexibility while the SAR and MPE standards are not exceeded, thereby avoiding the problems that the transmitting time is excessively reduced and the performance loss is serious due to excessive limitation, and simultaneously avoiding the problems that the link of the terminal device cannot be maintained and the link fails.
On the basis of the embodiment, after the network device receives the transmission energy residual value of the terminal device, the network device can directly increase or decrease the transmission power and/or the transmission time through the closed-loop power control information, and can also adjust the transmission power and/or the transmission time through adjusting the number of the resource blocks. Fig. 5 is a signaling interaction diagram of still another communication method according to an embodiment of the present application. As shown in fig. 5, on the basis of the above embodiment, the communication method includes:
s401, the terminal equipment determines a transmission energy residual value of a wireless signal of the terminal equipment in a first time period.
Wherein the transmission energy residual value is related to the transmission power and the transmission time of the terminal device.
S402, the terminal equipment sends the transmission energy residual value of the wireless signal to the network equipment.
The technical terms, effects, features, and exemplary embodiments of S401 to S402 may be understood with reference to S201 to S202 shown in fig. 2, and will not be described again here for repeated contents.
S403, the network device adjusts the number of the resource blocks allocated by the terminal device according to the transmission energy residual value sent by the terminal device, wherein the number of the resource blocks is related to the transmission power and the transmission time.
In this step, since the transmission power control formula is also affected by the number of resource blocks allocated to the terminal device by the network device, the network device can adjust the transmission power and the transmission time of the terminal device by increasing or decreasing the number of resource blocks allocated to the terminal device.
For example, if the transmission energy residual value is smaller, the network device may reduce the number of resource blocks allocated by the terminal device, thereby reducing the transmission power of the terminal device, increasing the transmission time of the terminal device, and avoiding the situation that the link of the terminal device cannot be maintained.
For example, if the transmission energy residual value is larger, the network device may increase the number of resource blocks allocated by the terminal device, thereby increasing the transmission power of the terminal device, reducing the transmission time of the terminal device, and improving the instantaneous rate of the communication service.
According to the communication method provided by the embodiment of the application, the quantity of the resource blocks allocated by the terminal equipment is adjusted according to the transmission energy residual value sent by the terminal equipment, so that the transmission power and/or the transmission time of the terminal equipment are adjusted. Because the network equipment adjusts the transmitting power of the terminal equipment based on the transmitting energy residual value, the transmitting power and the transmitting time of the terminal can be estimated more accurately, and the network is given enough scheduling flexibility while meeting the standard of SAR and MPE and not exceeding the standard, thereby avoiding the problems that the transmitting time is excessively reduced and the performance loss is serious due to excessive limitation, and simultaneously avoiding the problems that the link of the terminal equipment cannot be maintained and the link fails.
On the basis of the above-described embodiments, the transmission energy remainder of the wireless signal determined for the terminal device will be described below. Fig. 6 is a signaling interaction diagram of another communication method according to an embodiment of the present application. As shown in fig. 6, on the basis of the above embodiment, the communication method includes:
s501, the terminal equipment determines a transmission energy residual value of a wireless signal of the terminal equipment in a first time period.
Wherein the transmission energy residual value is related to the transmission power and the transmission time of the terminal device.
It should be noted that, the transmission energy residual value of the wireless signal in the first time period of the terminal device in this embodiment of the present application may be an available energy value between a certain time in the first time period and an end time of the first time period, may be an available energy value between a certain time in the first time period and a next time, or may be an available energy value between a start time and an end time of the first time period.
The detection time of the emission energy remainder will be described below.
In some embodiments, the first time period includes a plurality of moments in time; the energy remainder of the emission is an available energy value between a first time and an end time of the first time period, the first time being any time within the first time period. Fig. 7 is a schematic diagram of a method for reporting a residual value of transmission energy according to an embodiment of the present application. As shown in fig. 7, the first time period includes a plurality of moments, and the terminal device adopts a periodic reporting mode, and determines, at each moment, an available energy value between the first moment and an end moment of the first time period as a transmission energy residual value, and sends the transmission energy residual value to the network device.
For example, as shown in fig. 7, the terminal reports the transmission energy residual EHR1 at the beginning time of the first period, where EHR1 corresponds to the available energy value in the whole time length W1 of the first period. Subsequently, the terminal device may report the transmit energy residual EHR2 at time t1, where EHR2 corresponds to the available energy value in the time length W2 from t2 to the end time of the first period. Similarly, at the subsequent tn time, the terminal device reports the residual value of the emission energy. In this way, the network device can know the real-time schedulable energy allowance of the terminal in a certain period, so as to make reasonable arrangement for the overall service continuity and service performance.
In some embodiments, the first time period includes a plurality of moments in time; the energy remainder of the emission is an available energy value between a first time and a next time, the first time being any time within the first time period. Fig. 8 is a schematic diagram of another method for reporting a residual value of transmission energy according to an embodiment of the present application. As shown in fig. 8, the first time period includes a plurality of moments, and the terminal device adopts a periodic reporting mode, and determines an available energy value from the first moment to the next moment as a transmission energy residual value at each moment, and sends the available energy value to the network device.
As shown in fig. 8, the first period includes a start time, an end time, and intermediate times t1 and t2, where the times form three time sub-periods W1, W2, and W3, and the terminal device periodically reports the transmit energy residual value in each time sub-period. For example, the emission energy residual EHR1 in W1 is reported at the beginning of the first period, the energy residual EHR2 in W2 is reported at the time t1, and the energy residual EHR3 in W3 is reported at the time t 2. Wherein each sub-time period within the first time period is less than the first time period.
In some embodiments, the transmit energy residual is an available energy value between a start time and an end time of the first time period. Fig. 9 is a schematic diagram of another method for reporting a residual emission energy value according to an embodiment of the present application. As shown in fig. 9, the terminal device adopts a unique reporting manner of the transmission energy residual value of each time period, and reports the transmission energy residual value HER of W time length from the start time to the end time of the first time period at the start time of the first time period. In some embodiments, the transmitted energy residual HER reported in this way may be reported as a static terminal capability when the terminal device initially accesses the network.
S502, if the transmission energy residual value is smaller than the energy threshold value, the terminal equipment sends the transmission energy residual value to the network equipment.
In this step, after the terminal device determines the transmission energy residual value in the first period, the transmission energy residual value may be compared with the energy threshold, and if the transmission energy residual value is smaller than the energy threshold, it indicates that the transmission energy residual value of the terminal device exceeds the alarm value, and the transmission power and/or the transmission time of the terminal device need to be adjusted, where the transmission energy residual value may be transmitted to the network device. If the transmission energy residual value is not smaller than the energy threshold value, the transmission energy residual value of the terminal equipment does not exceed the warning value, and the adjustment of the transmission power and/or the transmission time of the terminal equipment is not needed, and the transmission energy residual value is not needed to be transmitted to the network equipment. The energy threshold may be preset, may be a fixed value, or may decrease over time.
In some embodiments, if the terminal device determines that the transmit energy residual value is less than the energy threshold, the terminal device sends alarm information to the network device, where the alarm information may carry the transmit energy residual value, and the alarm information causes the network device to reduce the transmit power of the terminal device and increase the transmit time of the terminal device, so as to maintain the link of the terminal device.
Fig. 10 is a schematic diagram of another method for reporting a residual emission energy value according to an embodiment of the present application. As shown in fig. 10, when the terminal device detects that the available transmission energy margin at time t is lower than the energy threshold, the terminal device sends an alarm message to the network device at this time, and timely informs the network device of the remaining energy margin EHR', so that the network device can adjust the transmission power and/or transmission time of the terminal device in time, and avoid the problem of link failure caused by the lack of energy margin.
It should be noted that, the transmission energy residual value reporting mode by comparing with the energy threshold may be used in combination with the transmission energy residual value reporting modes provided in fig. 7 to fig. 9.
In the communication method provided by the embodiment of the application, if the transmission energy residual value of the wireless signal of the terminal device is smaller than the energy threshold value, the terminal device sends alarm information to the network device, wherein the alarm information comprises the transmission energy residual value of the wireless signal of the terminal device. By the method, the transmitting energy residual value of the terminal equipment can be monitored under the condition that the transmitting energy residual value is not frequently transmitted to the network equipment, and reporting adjustment can be timely carried out after the transmitting energy residual value reaches the warning value, so that the problems that the transmitting time is excessively shortened and the performance loss is serious due to excessive limitation are avoided, and meanwhile, the problem that the link of the terminal equipment cannot be maintained and the link fails are also avoided.
