Description

Method for determining back-off power and method for adjusting transmission power

Technical Field

The present application belongs to the field of communications technologies, and in particular, to a method and an apparatus for determining a back-off power, a method and an apparatus for adjusting a transmit power, an electronic device, and a computer-readable storage medium.

Background

The Specific Absorption Rate (SAR) refers to the amount of electromagnetic radiation absorbed per kilogram of human tissue in 6 minutes. The SAR value is used for measuring the influence of heat energy generated by electromagnetic waves in electronic equipment such as mobile phones on human bodies and the like, and the unit is watt/kilogram (W/Kg). The larger the SAR value is, the larger the influence on the human body is; otherwise, the influence is small.

And corresponding mandatory management requirements are made for each country or region of the SAR value. That is, the SAR value is used to quantify and measure the electromagnetic radiation of the electronic equipment such as the mobile phone, and whether the influence of the electromagnetic radiation of the electronic equipment on the human body meets the standard or not is measured. The standard adopted in the united states is that the peak value of SAR received by a human body is lower than 1.6W/kg in a unit of mass of 1 gram. The standard adopted by China and the European Union is that the average value of SAR received by a human body is lower than 2.0W/kg by taking 10 g as a mass unit.

To improve the uplink coverage and rate of the network, operators have put forward standardization demands on high-power electronic devices in multiple frequency bands. When the transmission power of the electronic equipment rises, if the ratio of the uplink resource to the downlink resource is not proper, the SAR value cannot meet the regional requirement, and thus the human body is damaged.

The embodiment of the application provides a method and a device for determining back-off power, a method and a device for adjusting transmission power, electronic equipment and a computer readable storage medium, which can solve the technical problem of how to enable the SAR value of terminal equipment to meet the regional requirement in the related technology.

In a first aspect, an embodiment of the present application provides a method for determining a back-off power, which is applied to an electronic device, and the method includes: the method comprises the steps of firstly identifying the current service scene of the electronic equipment as a voice service scene, then determining the uplink proportion of a voice packet according to the voice system of the voice service scene, and finally determining the backspacing power according to the uplink proportion. According to the embodiment of the application, the uplink proportion corresponding to the voice service scenes of different voice systems is considered not to reach 100%, and the power backoff is determined based on the uplink proportion, so that the transmission power of the fixed SAR value reduction scheme is improved.

In a second aspect, an embodiment of the present application provides a method for adjusting transmission power, which is applied to an electronic device, and the method includes: the method comprises the steps of firstly identifying the current service scene of the electronic equipment as a voice service scene, then determining the uplink proportion of a voice packet according to the voice system of the voice service scene, then determining the backspacing power according to the uplink proportion, and finally determining the target maximum transmitting power based on the transmitting power of a fixed-reduction SAR value scheme and the backspacing power. According to the embodiment of the application, the uplink proportion corresponding to the voice service scenes of different voice systems is considered not to reach 100%, and the power backoff is determined based on the uplink proportion, so that the transmission power of the fixed SAR value reduction scheme is improved. The technical problem of excessive emission power reduction caused by the fact that the SAR value region requirement is met in a fixed SAR value reduction scheme is solved.

In a possible implementation manner of the first aspect or the second aspect, the voice system includes: VoLTE, VoIP, CS call or VoNR.

In another possible implementation manner of the first aspect or the second aspect, before determining the back-off power corresponding to the uplink occupied ratio, the method further includes:

and judging whether the service rate of the data service meets a preset condition, and if the service rate of the data service meets the preset condition, replacing the step of determining the back-off power corresponding to the uplink duty ratio with the step of determining the back-off power corresponding to the uplink duty ratio or determining the back-off power corresponding to the uplink duty ratio higher by one.

Illustratively, the current service scenario of the electronic device includes not only a voice service scenario but also a data service scenario.

If the data service meets the condition of the low-rate service, the current service scene of the electronic equipment can still be analogized to a pure voice service scene. At this time, the backoff power corresponding to the uplink duty ratio of the first higher rank of the voice format may be determined according to the conditional number of the low-rate service, or the backoff power corresponding to the uplink duty ratio of the voice format may be determined. Then, the target transmitting power is confirmed based on the transmitting power of the fixed SAR reduction scheme under the voice service scene and the backspacing power

In another possible implementation manner of the first aspect or the second aspect, after the determining whether the traffic rate of the data service meets a preset condition, the method further includes:

if the service rate of the data service does not meet the preset condition, identifying a transceiving module for transceiving the data service;

and determining the back-off power corresponding to the data service through the transceiver module.

If the modem of the electronic device identifies that the current service scene comprises a voice service scene, the application processor identifies that the current service scene also comprises a data service scene, and the current service scene belongs to the situation of multi-service scene concurrence. The electronic device determines that the data service does not satisfy the condition of the low-rate service, and at this time, the current service scene is not analogized to a pure voice service scene. And determining a current transceiving module for transceiving the data service according to the situation of the concurrence of the multiple service scenes.

For example, if the transceiver module performing the data service is also a modem as the same as the voice service scenario, the modem determines an uplink duty ratio corresponding to the service scenario in which the voice service and the data service are combined according to a mapping relationship among a pre-stored service scenario, the uplink duty ratio and the back-off power, and determines the back-off power corresponding to the uplink duty ratio. And then calculating the target maximum transmitting power of the modem according to the back-off power and the transmitting power of the fixed-drop SAR scheme.

For another example, if the transceiver module performing the data service is not a modem, but another transceiver module such as a WI-FI module or a BT module, on one hand, the modem identifies a voice format of a current voice service scenario, determines an uplink occupation ratio corresponding to the voice format, and then determines a back-off power according to the uplink occupation ratio, so as to obtain a target maximum transmit power of the modem according to the back-off power and a transmit power of a fixed-reduction SAR scheme. On the other hand, the WI-FI module or the BT module identifies the current data service scene, determines the uplink ratio corresponding to the data service scene, and then determines the back-off power according to the uplink ratio, so that the target maximum transmitting power of the WI-FI module or the BT module is obtained according to the back-off power and the transmitting power of the fixed SAR reduction scheme.

The power backoff is determined based on the application service scene, so that the transmission power of the fixed-reduction SAR value scheme is improved. The technical problem of excessive emission power reduction caused by the fact that the SAR value region requirement is met in a fixed SAR value reduction scheme is solved.

According to the embodiment of the application, the uplink occupation ratios corresponding to different application service scenes cannot reach 100%, and the backspacing power of the transceiver module is determined based on the application service scenes, so that the transmitting power of the fixed SAR value reduction scheme is improved. The technical problem of excessive emission power reduction caused by the fact that the SAR value region requirement is met in a fixed SAR value reduction scheme is solved.

In a possible implementation manner of the third aspect or the fourth aspect, if the electronic device identifies that the current service scenario is an application service scenario, the application processor identifies the current application service scenario and the transceiver module of the application data. The application processor sends the identification result to the transceiver module, and determines the backspacing power corresponding to the current application service scene through the transceiver module; and finally, determining the target maximum transmitting power of the transceiver module based on the transmitting power of the fixed SAR value reduction scheme and the back-off power.

For example, if one transceiver module is identified, the application processor issues the identification result to the transceiver module, and determines the back-off power corresponding to the application service scenario through the transceiver module, so as to obtain the target maximum transmission power of the transceiver module according to the back-off power and the transmission power of the fixed-reduction SAR scheme.

For another example, if the identified transceiver module is multiple (two or more), such as modem or WI-FI module. The application processor sends the recognition result to the plurality of transceiver modules, for example, the application service that the modem is responsible for transceiving may be sent to the modem, and the application service that the WI-FI module is responsible for transceiving may be sent to the WI-FI module. Then, on one hand, the corresponding back-off power is determined by the modem according to the application service scenario, so that the target maximum transmit power of the modem is obtained according to the back-off power and the transmit power of the fixed-reduction SAR scheme.

Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

To explain the technical means of the present application, the terms of the present application will be explained.

In this embodiment of the present application, the uplink occupancy refers to a ratio of a duration corresponding to a transmission resource of uplink information in a time window when a base station is an electronic device, such as a User Equipment (UE), and performs transmission resource configuration. One time window comprises a plurality of unit information transmission time, the time window can be any time length, and the time length of the time window is not specifically limited in the application. The base station may configure transmission resources for the electronic device, where the transmission resources include transmission resources of uplink information and transmission resources of downlink information.

For example, the uplink occupancy is 100%, which means that 100% of the time domain resources are configured as transmission resources for uplink information in a time window. As another example, the uplink accounts for 50%, which means that 50% of the time domain resources are configured as transmission resources for uplink information in a time window.

It should be understood that the unit information transmission time may be different in different communication systems. For example, in a Long Term Evolution (LTE) communication system, a unit information transmission time may be one subframe (subframe). In a New Radio access mode (NR), such as a 5G communication system, a unit information transmission time may be a slot, a mini-slot (mini-slot), or a symbol (symbol).

More generally, when a communication device interacts with other communication devices to achieve data transmission, the uplink duty cycle refers to the proportion of the transmission duration of the communication device in a time window. For example, the uplink occupancy is 100%, which means that 100% of the time domain resources are configured to transmit information within a time window. As another example, uplink accounts for 50%, meaning that 50% of the time domain resources are configured to transmit information within a time window.

In order to explain the technical means of the present application, the following description will be given by way of specific examples.

To improve the uplink coverage and rate of the network, operators have put forward standardization demands on high-power electronic devices in multiple frequency bands. When the transmission power of the electronic equipment rises, if the ratio of the uplink resource to the downlink resource is not proper, the SAR value exceeds the regional standard.

In order to make the SAR value of the electronic device meet the regional requirement, a scheme of fixedly reducing the SAR value is presented. In the scheme, for each working mode of the electronic equipment, SAR values corresponding to different distances from a human body to the electronic equipment are tested according to a limit scene, namely according to the maximum transmission power and 100% uplink ratio (or uplink transmission time) in 6 minutes. And if the SAR exceeds the regional standard, determining new transmission power, and ensuring that the SAR value does not exceed the standard under the new transmission power.

The working mode of the electronic equipment is a mode for transmitting and receiving data by using different transmitting and receiving modules or a combination thereof. The transceiver module includes, but is not limited to, a modem processor (modem), a wireless fidelity (Wi-Fi) module, or a Bluetooth (BT) module.

Therefore, in the testing stage before the electronic equipment leaves the factory, the emission power reduction amplitude corresponding to different man-machine distances in each working mode is determined according to the limit scene. The following table shows the transmit power reduction for different man-machine distances in the modem processor (modem) operating mode for transceiving data. Wherein, the transmission power amplitude reduction is the power amplitude reduction based on the maximum transmission power. It should be understood that table one is merely an exemplary description.

Watch 1

Distance between man and machine	Power amplitude reduction based on maximum transmitting power
		x₁	y₁ dBm
x₂	y₂ dBm
		x₃	y₃ dBm
x₄	y₄ dBm
		……	……
x_n	y_n dBm

In an actual service scenario, a modem processor (modem) of the electronic device is used for transceiving data, and a distance sensor of the electronic device detects an actual distance from the electronic device to a human body. And according to the actual distance, determining the emission power reduction amplitude corresponding to the actual distance by the first lookup table, and reducing the maximum emission power according to the emission power reduction amplitude, so that the SAR value meets the regional requirement.

Based on the scheme, when the SAR value exceeds the standard, the electronic device reduces the maximum transmission power so as to reduce the SAR value. Since the actual service scenarios of the electronic device are many, the testing phase needs to cover the requirements of all service scenarios. Then the limiting scenario for the SAR value test is full uplink transmission, which results in a very large power reduction per unit time. But when the actual scene does not reach 100% uplink occupation ratio, the transmission power is reduced.

For example, when the human body is at a certain distance from the human-machine of the electronic device, in the testing process, according to the requirement that the SAR limit value is 1.6W/Kg for 6 minutes in the test, in order to meet 100% uplink occupancy, the maximum transmitting power obtained by the test needs to be reduced from 23 dB/mW (unit: dBm) to 20 dBm. However, in the actual service scene with the same man-machine distance, if the uplink occupation ratio is only 50%, the actual emission time of the electronic equipment within 6 minutes is only 3 minutes, and the SAR value is only 0.8W/Kg according to the emission power of 20 dBm. It can be seen that the 3-minute transmission time can increase the transmission power by 3dBm, and the SAR value can reach 1.6W/Kg.

Therefore, in order to solve the technical problem that the transmission power is reduced too much in order to prevent the SAR value from exceeding the standard in the fixed SAR value reduction scheme, the application provides a method for adjusting the transmission power. On the basis of the fixed SAR value reduction scheme, the transmitting power is lifted, so that the resource waste caused by excessive reduction of the transmitting power is avoided.

In the embodiment of the application, the method for adjusting the transmission power can be applied to the electronic equipment needing to adjust the transmission power. The electronic device may include a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a sound box, a base station, and the like, and the embodiment of the present application does not limit the specific type of the electronic device.

By way of example and not limitation, when the electronic device is a wearable device, the wearable device may also be a generic term for intelligently designing daily wear, developing wearable devices, such as glasses, gloves, watches, clothing, shoes, and the like, by applying wearable technology. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable intelligent device has the advantages that the generalized wearable intelligent device is complete in function and large in size, can realize complete or partial functions without depending on a smart phone, such as a smart watch or smart glasses, and only is concentrated on a certain application function, and needs to be matched with other devices such as the smart phone for use, such as various smart bracelets for monitoring physical signs, smart jewelry and the like.

A first application scenario of the method of adjusting transmit power of the embodiments of the present application is presented.

The first application scenario is a voice service scenario. Here, a Voice over Long-Term Evolution (VoLTE) service scenario is taken as an example for explanation.

Fig. 2 shows a voice traffic model for VoLTE. The voice service model reflects the transmission rule of the data packet in the VoLTE service. As shown in fig. 2, the state of VoLTE service includes an activation Period (Talk Spurt) and a silence Period (silence Period). The active period is also called the talk period. During the active period, the packet transmission interval of the voice data packets is 20ms, and the size of each voice data packet is about 35 to 47 bytes (unit: Byte). During the Silence period, the transmission interval of Silence Indication (SID) packets is 160ms, and the size of each SID packet is about 10 to 22 bytes. As can be seen from the voice service model, the VoLTE service has the characteristics of small packet size, relatively fixed packet size, and relatively fixed arrival interval.

Since the voice traffic is the traffic with qci (qos Class identifier) equal to 1, the traffic has the highest priority. The higher the traffic priority, the higher the priority of the base station scheduling. Therefore, the base station will preferentially schedule voice traffic. In addition, based on the regularity of voice traffic, the base station typically starts Semi-persistent scheduling (SPS) after entering the active period. Semi-persistent scheduling is started and voice data packets are scheduled once every 20 ms.

An example of a base station (eNodeB) turning on semi-persistent scheduling is shown in fig. 3. An Evolved Radio Access Bearer (E-RAB) is used for transmitting voice, data and multimedia services between a UE and a Core Network (CN). E-RAB establishment is initiated by CN, when E-RAB establishment is successful (set up), a basic service is established, UE enters into service using process. In the example of fig. 3, E-RAB establishment is initiated by the 4G Core network (EPC), and after the E-RAB establishment is successful, it is used for the UE to enter the voice service usage process. The eNodeB notifies the semi-persistent scheduling information to the UE, such as a mobile phone, through Radio Resource Control (RRC) signaling, where the content includes a semi-persistent scheduling period and related parameters of the semi-persistent scheduling. The UE is then informed via a Physical Downlink Control Channel (PDCCH) when to start semi-persistent scheduling (i.e., activate semi-persistent scheduling) and when to end semi-persistent scheduling (i.e., deactivate semi-persistent scheduling). The UE in the semi-persistent scheduling state may also monitor the scheduling command of the PDCCH at any time, and may increase the transmission rate by using dynamic scheduling at any time, so as to cope with the burst traffic that may be brought by other data services while the VoIP service is in progress.

A Transmission Time Interval (TTI) bundling technique is also proposed in VoLTE, and bundling is performed for consecutive TTIs in uplink. The number of TTIs consecutively transmitted in the TTI bundling, i.e., TTIbundle _ Size, is defined as 4.

Under the VoLTE scene, when semi-static scheduling is started and a TTI bundling function is started, a voice data packet is scheduled once every 20 ms. A maximum of 4 TTIs can be transmitted consecutively, i.e. a maximum of 4ms can be transmitted consecutively. It can be calculated that in VoLTE voice scenario, the maximum uplink share is 4/20-20%. The Quality of Service (QoS) of voice Service has the highest grade, and the network is limited to meet the scheduling requirement, so the uplink percentage in the VoLTE scene does not exceed 20%.

Combining the above-mentioned fixed SAR value reduction scheme, in the testing stage, in order to make the test cover all service scenarios, the limit condition set is full uplink transmission, i.e. the uplink ratio is 100%. However, in actual service scenarios, the possibility of full uplink transmission is very low, for example, in scenarios such as live broadcast and uplink packet, the base station may use the full uplink occupancy. In most service scenarios, the uplink occupancy is lower than 100%, for example, in the aforementioned VoLTE voice scenario, the uplink occupancy is 20%. If the above-mentioned fixed SAR reduction scheme is also adopted, the transmission power is reduced too much. That is, if the transmit power is reduced according to the limit scenario only to satisfy a few traffic scenarios, most of the reduced power is wasted.

Therefore, in the embodiment of the present application, it is proposed to distinguish actual service scenarios of electronic devices, determine uplink ratios, and obtain back-off powers of maximum transmission powers corresponding to different uplink ratios. Therefore, the electronic equipment performs power backoff or power boost on the basis of reducing the transmission power by the fixed SAR value reduction scheme, and solves the technical problem of excessive transmission power reduction.

In this embodiment of the present application, the power backoff refers to performing transmit power backoff to raise transmit power or reduce transmit power backoff on the basis of transmit power backoff corresponding to an actual distance in the foregoing fixed SAR value reduction scheme.

It should be understood that, besides the above-mentioned VoLTE system, there are also other Voice system Voice service scenarios, such as Voice over IP (VoIP), Circuit Switched (CS) domain Voice transmission (CS call), or New wireless access mode Voice transmission (VoNR). In the voice service scenes of different voice systems, the uplink ratios are different. In the embodiment of the present application, in a testing stage before leaving a factory, in addition to determining power reduction ranges corresponding to different distances according to a limit scenario of full uplink transmission, different uplink occupation ratios under different voice service scenarios and back-off power of corresponding maximum transmission power need to be determined.

As a non-limiting example of the present application, the uplink proportion of the speech service scene of each speech system may be determined through the interaction information between the electronic device and the base station. And measuring the transmitting power which meets the requirement that the SAR value does not exceed the standard under different voice service scenes by a power meter, and then calculating the backspacing power corresponding to each uplink occupation ratio.

As another non-limiting example of the present application, the uplink occupation ratio in each language service scenario may be determined through interaction information between the electronic device and the base station. And then, measuring the transmitting power which meets the condition that the SAR value does not exceed the standard when the uplink proportion of 100 percent is measured by a power meter, and deducing the back-off power corresponding to the uplink proportion of 100 percent. And then, calculating the back-off power corresponding to each uplink occupation ratio according to the proportion that the back-off power is increased by 3dBm when the uplink occupation ratio is reduced by 50 percent.

Exemplarily, when the electronic device is in a voice service scenario, the back-off power of the maximum transmission power corresponding to different uplink occupation ratios is shown in table two.

Watch two

		(90％～100％]	0dBm

And the second table comprises the mapping relation of the back-off power corresponding to different uplink occupation ratios under the condition that the uplink occupation ratios are different. After the mapping relationship is obtained, the mapping relationship may be deployed in the electronic device for subsequent invocation.

It should be understood that the values in table two are merely exemplary descriptions, which indicate that the uplink occupation ratios of different value intervals correspond to one backoff power, and the mapping relation table of the actual situation may be different from table two. Alternatively, the division of the numerical intervals may be different; the magnitude of the back-off power may also be different.

Fig. 4 is a flowchart illustrating a method for adjusting transmission power according to an embodiment of the present application. The method of adjusting transmission power is applicable to electronic devices, such as, for example, cell phones. As shown in fig. 4, the method for adjusting the transmission power includes steps S410 to S440. The specific realization principle of each step is as follows:

and S410, identifying the current service scene as a voice service scene.

The current service scenario is a service scenario in progress of the electronic device, and the service scenario includes, but is not limited to, a voice service scenario, an application service scenario, or a data service scenario.

Since the modem can recognize whether the electronic device is conducting voice services. Therefore, in the embodiment of the application, the current service scenario can be identified as the voice service scenario through the modem processor. It should be noted that, in the embodiment of the present application, the voice service scenario is a pure voice (voice only) service scenario, that is, a scenario with only a voice service. In the following embodiments, a case where multiple service scenarios exist, that is, multiple services are concurrent, will be described. For example, an electronic device not only performs voice services, but also performs other services, such as data services, simultaneously. A third subsequent application scenario has a relevant introduction. In the embodiments of the present application, a pure voice service scenario is introduced.

S420, determining a voice system of the voice service scene, and determining the uplink voice packet ratio according to the voice system.

The voice system of the voice service scenario includes but is not limited to: VoLTE, VoIP, CS call or VoNR, etc. Different voice systems correspond to different uplink occupation ratios. The uplink occupation ratios corresponding to different voice systems are preset values obtained according to communication requirements and the like. For example, for a voice service scenario of a VoLTE system or a VoNR system, the uplink percentage of the voice packet is 20%. Therefore, in the embodiment of the present application, the voice system of the voice service scenario is determined first, and then the uplink proportion of the voice packet is determined according to the voice system.

In some embodiments of the present application, the electronic device prestores mapping relationships between different systems and uplink occupation ratios. And searching the uplink occupation ratio corresponding to the system according to the mapping relation.

In some embodiments of the present application, a voice format of a voice service scene is determined by a modem, and then an uplink proportion of a voice packet is determined according to the voice format.

S430, determining the emission power reduction amplitude corresponding to the current man-machine distance; and determining the back-off power corresponding to the uplink occupation ratio.

The transmission power reduction amplitude represents the power reduction amplitude of the maximum transmission power corresponding to any man-machine distance in a limit scene, namely under the condition that the uplink occupancy is 100%. The back-off power means a power that is increased or increased based on a transmission power reduction of the maximum transmission power.

It should be understood that the electronic device prestores a mapping relationship between different human-machine distances and transmission power reduction amplitudes, such as the mapping relationship shown in table one. The electronic device prestores mapping relationships between different uplink ratios and the back-off power, for example, the mapping relationship shown in table two.

In an embodiment of the application, a human-machine distance between a user and an electronic device (or between the user and an antenna) is determined by a distance sensor of the electronic device. And then, searching the mapping relation between the man-machine distance and the emission power reduction amplitude according to the current man-machine distance, and determining the emission power reduction amplitude corresponding to the current man-machine distance.

And searching a mapping relation between the uplink occupation ratio and the backspacing power through a modem of the electronic equipment, and determining the backspacing power corresponding to the uplink occupation ratio of the current voice system.

S440, determining a target transmission power based on the transmission power reduction amplitude and the back-off power.

Wherein the transmit power reduction and the back-off power are determined at step S430. In step S440, a target transmit power is determined according to the transmit power reduction and the back-off power. The target transmitting power is the target maximum transmitting power after the electronic equipment performs power lifting on the basis of the fixed SAR reduction scheme. The electronic device may control the uplink transmission power according to the target transmission power, that is, the electronic device may transmit data at the uplink transmission power not greater than the target transmission power.

In some embodiments of the present application, in step S440, the power reduced on the basis of the maximum transmission power is first determined according to the transmission power reduction and the back-off power. A target transmit power is then determined based on the maximum transmit power and the power reduced based on the maximum transmit power.

Optionally, the target transmit power is the maximum transmit power- (transmit power reduction-back-off power). The back-off power is positive at this time.

Optionally, the target transmit power is the maximum transmit power- (transmit power reduction + back-off power). The back-off power is negative at this time.

In other embodiments of the present application, in step S440, a target transmit power is determined according to the transmit power reduction, the back-off power, and the maximum transmit power.

Optionally, the target transmit power is the maximum transmit power-transmit power reduction plus the back-off power. The back-off power is positive at this time.

Optionally, the target transmit power is maximum transmit power-transmit power reduction amplitude-backoff power. The back-off power is negative at this time.

It should be understood that in the embodiment of the present application, the back-off power may be a positive value or a negative value. This is not limited by the present application. For convenience of understanding, in the following embodiments or examples, the back-off power is taken as a negative value as an example for explanation. It should be emphasized that, on the basis of reducing the maximum transmission power by a transmission power reduction amplitude, a certain power is raised, where the raised certain power corresponds to the back-off power.

In some embodiments of the present application, the target transmit power may be calculated by a modem of the electronic device. In other embodiments of the present application, the transmit power may also be calculated by a processor other than the modem.

As a non-limiting example, the present example is directed to a voice traffic scenario of VoLTE format. Suppose the maximum transmit power of the electronic device is Q23 dBm. The modem of the electronic device presets the mapping relationship as shown in table two.

In the testing stage, under the condition of obtaining the limit language service scene of the full uplink transmission, when the actual distance between the user and the electronic equipment is x centimeters (unit: cm), the transmission power reduction amplitude of the corresponding maximum transmission power is 10 dBm.

In an actual voice service scene, if the distance sensor of the electronic device recognizes that the distance from the user to the electronic device is x cm, and the modem of the electronic device recognizes that the electronic device is in a voice service scene of a VoLTE system. And determining the uplink occupation ratio of the voice service scene to be 20% according to the VoLTE system. And then, the back-off power of the maximum transmitting power corresponding to the uplink percentage of 20 percent is determined to be-7 dBm by looking up the mapping relation shown in the table II. The target maximum emission power of the electronic device is adjusted to decrease by 10-7 to 3dBm based on 23dBm of the maximum emission power Q. That is, the target maximum transmission power is adjusted to Q- (10-7) ═ Q-3 ═ 20 dBm.

According to the example, the fixed SAR value reduction scheme needs to reduce the transmission power of a voice service scene by 10dBm from 23dBm, that is, the transmission power is 13 dBm. Based on the technical scheme of the application, the transmitting power of the VoLTE system voice service scene only needs to be reduced by 3dBm from 23dBm, namely the transmitting power is 20 dBm. Therefore, the transmission power is increased on the basis of the fixed SAR value reduction scheme.

Next, a second application scenario of the method for adjusting transmission power according to the embodiment of the present application is described.

The service scenes of the electronic device include not only voice service scenes but also data service scenes, such as application service scenes. The Application service scene includes, but is not limited to, a scene in which an electronic device runs an Application program (APP), and the like. In the second application scenario, a case where the service scenario of the electronic device is an application service scenario is considered.

In a second application scenario, in a test stage before the electronic device leaves a factory, a laboratory extracts a possible maximum uplink occupancy rate corresponding to the electronic device running a single APP and/or multiple APPs. When the electronic device, such as a mobile phone, is in operation, the application processor may identify a current application service, and may also determine which transceiver module is transmitting and receiving data of the currently running application service. The transceiver module includes but is not limited to modem, WI-FI module or BT module. The modem receives and transmits mobile communication data, and the WI-FI module and the BT module receive and transmit wireless communication data. And data is transmitted and received through different transmitting and receiving modules corresponding to different communication scenes, such as cellular or WLAN.

In the second application scenario, in the testing stage before delivery, except that the power reduction amplitudes corresponding to different distances are determined according to the limit scenario of full uplink transmission. And determining the back-off power of the maximum transmitting power corresponding to different uplink occupation ratios and different maximum transmitting powers of the transceiver modules in different application service scenes.

As a non-limiting example of the present application, the application processor of the electronic device may identify different application service scenarios and identify which transceiver module is used for data transceiving. When service data is received and transmitted through the modem and the WI-FI module, the uplink occupation ratio of the receiving and transmitting module under different application service scenes can be determined through the interactive information of the electronic equipment and the base station; when business data is received and sent through the BT module, the uplink occupation ratio of the receiving and sending module under different application business scenes can be determined through the BT module. And measuring the transmitting power which meets the requirement that the SAR value does not exceed the standard under different uplink occupation ratios by a power meter, and then calculating the back-off power corresponding to each uplink occupation ratio.

As another non-limiting example of the present application, the application processor of the electronic device may identify different application service scenarios and identify which transceiver module is to transceive data. When service data is received and transmitted through the modem and the WI-FI module, the uplink occupation ratio of the receiving and transmitting module under different application service scenes can be determined through the interactive information of the electronic equipment and the base station; when business data is received and sent through the BT module, the uplink occupation ratio of the receiving and sending module under different application business scenes can be determined through the BT module. And then, measuring the transmitting power which meets the condition that the SAR value does not exceed the standard when the uplink proportion of 100 percent is measured by a power meter, and deducing the back-off power corresponding to the uplink proportion of 100 percent. And then, calculating the back-off power corresponding to each uplink occupation ratio according to the proportion that the back-off power is increased by 3dBm when the uplink occupation ratio is reduced by 50 percent.

Illustratively, when data transceiving is performed through the modem, the mapping relationship between the application service, the uplink occupation ratio and the back-off power of the maximum transmission power is shown in table three.

Watch III

In the third table, A, B, C, D, E, F, G and H represent respectively a different APP. The third table shows a plurality of up ratio gears. The range of the uplink ratio is divided into 10 gears according to the size sequence from 0 to 100%. Each gear can correspond to a single APP and also can correspond to a combination of multiple APPs. It should be understood that table three is not exhaustive, and the numbers and application services in table three are only examples, and the mapping relationship table of the actual situation may be different from table three.

After the mapping relationship is obtained, the mapping relationship may be deployed in the electronic device for subsequent invocation. In the application scenario, each transceiver module may preset a mapping relationship.

Fig. 5 is a flowchart illustrating a method for adjusting transmission power according to an embodiment of the present application. The method of adjusting transmission power is applicable to electronic devices, such as, for example, cell phones. The embodiment shown in fig. 5 considers the case of an application service scenario, rather than a voice service scenario. Accordingly, another way of determining the back-off power is provided. It should be understood that the embodiment of fig. 5 is the same as the embodiment of fig. 4, and the description thereof is omitted here, please refer to the related description of fig. 4. As shown in fig. 5, the method for adjusting the transmission power includes steps S510 to S540. The specific realization principle of each step is as follows:

s510, identifying the current application service scene, and identifying a transceiver module for transmitting and receiving application data.

The current application service scene refers to identifying that the current service scene of the electronic equipment is an application service scene. The receiving and transmitting module is a module for receiving and transmitting service data. The transceiver module includes, but is not limited to, modem, WI-FI module and BT module.

Since the application processor can parse the application content of the package, the application service scenario of the electronic device can be identified. In some embodiments of the present application, a current application business scenario may be identified by an application processor. In addition, the application processor identifies the transceiver module that transmits and receives application data.

S520, determining the uplink ratio corresponding to the current application service scene through the transceiver module.

Wherein, the corresponding uplink occupation ratios of single different application services or the combination of a plurality of application services are different. For example, the uplink occupancy corresponding to the uplink filling packet is 100%, the uplink occupancy corresponding to the live broadcast is 90%, the uplink occupancy corresponding to the navigation is 30%, and the uplink occupancy corresponding to the combination of the navigation and the web browsing is 40%.

In some embodiments of the present application, different transceiver modules of the electronic device respectively pre-store mapping relationships between different service scenarios and uplink occupancy rates. And searching the uplink ratio corresponding to the current application service scene according to the mapping relation.

In some embodiments of the present application, different transceiver modules of an electronic device respectively pre-store mapping relationships between different service scenarios, uplink occupation ratios and back-off powers based on maximum transmission power. And searching the uplink ratio corresponding to the current application service scene according to the mapping relation.

In some embodiments of the present application, after the application processor identifies the current application service scenario and identifies the transceiver module, the transceiver module is notified of the current application service scenario, and the transceiver module determines the uplink occupancy corresponding to the current application service scenario.

S530, determining the back-off power corresponding to the uplink occupation ratio.

In some embodiments of the present application, a transceiver module of an electronic device searches for a mapping relationship between an uplink duty ratio and a back-off power, and determines a back-off power corresponding to the uplink duty ratio.

In some embodiments of the present application, different transceiver modules of an electronic device respectively pre-store a first mapping relationship between different service scenarios and uplink occupancy ratios, and a second mapping relationship between different uplink occupancy ratios and backoff power based on maximum transmit power. And searching the uplink ratio corresponding to the current application service scene according to the first mapping relation. And searching the back-off power based on the maximum transmitting power corresponding to the uplink occupation ratio according to the second mapping relation.

In some embodiments of the present application, different transceiver modules of an electronic device respectively pre-store mapping relationships between different service scenarios, uplink occupation ratios and back-off powers based on maximum transmission power. And searching an uplink ratio corresponding to the current application service scene according to the mapping relation, and determining the back-off power based on the maximum transmitting power corresponding to the uplink ratio.

As a non-limiting example, the transceiver module is a modem, and the electronic device prestores a mapping relationship between an application service, an uplink occupation ratio and a back-off power, for example, the mapping relationship shown in table three.

S540, determining the transmitting power amplitude reduction corresponding to the current man-machine distance, and determining the target transmitting power based on the transmitting power amplitude reduction and the backspacing power.

The back-off power is determined in step S530. Besides determining the backspacing power, the emission power reduction amplitude corresponding to the current man-machine distance is also determined. And then, determining target transmitting power based on the transmitting power amplitude reduction and the backspacing power, thereby realizing the lifting of the transmitting power on the premise of meeting the SAR value requirement. For this part, please refer to the description of the embodiment shown in fig. 4, which is not repeated herein.

It should be understood that, in the embodiment shown in fig. 5, the determining of the transmission power reduction amplitude corresponding to the current man-machine distance in step S540 is only performed before the determining of the target transmission power based on the transmission power reduction amplitude and the back-off power in step S540, and there is no time requirement between steps S510, S520, and S530.

As a non-limiting example, in the present example, the current application service scenario of the electronic device is to run an application E and an application F, and data transceiving is performed through the modem. Suppose the maximum transmit power of the electronic device is Q23 dBm. The modem of the electronic device presets the mapping as shown in table three.

In the testing stage, data receiving and transmitting through the modem are obtained, and in the limit scene of full uplink transmission, when the actual distance between the user and the electronic equipment is x centimeters (unit: cm), the transmission power reduction amplitude of the corresponding maximum transmission power is 10 dBm.

In the actual application service scene, if the distance sensor of the electronic device identifies that the distance from the user to the electronic device is x cm, and the application processor of the electronic device identifies that the current application service scene is an operating application E and an application F, the transceiver module for data transceiving is identified as modem. And the application processor sends the current application service scene to the modem. And the Modem determines that the uplink proportion corresponding to the application E and the application F is 20 to 30 percent and the back-off power corresponding to the uplink proportion of 20 to 30 percent is-5.2 dBm through the mapping relation of the lookup table III. The target maximum emission power of the electronic device is adjusted to decrease by 10-5.2 dBm to 4.8dBm based on 23dBm for the maximum emission power Q. That is, the target maximum transmission power is Q- (10-5.2) ═ Q-4.8 ═ 18.2 dBm.

As can be seen from this example, in the fixed SAR value reduction scheme, the transmission power of the application service scenario needs to be reduced by 10dBm from 23dBm, that is, the transmission power is 13 dBm. Based on the technical scheme of the application, the transmitting power of the application service scene for running the application E and the application F only needs to be reduced by 4.8dBm from 23dBm, namely the transmitting power is 18.2 dBm. Therefore, on the basis of the fixed SAR value reduction scheme, the back-off power which can meet the SAR value requirement is determined through the modem, the WI-FI module or the BT module according to the uplink ratio of different application services, and the transmitting power is increased.

As another non-limiting example, in the present application service scenario of the electronic device, an application E and an application F are executed, data transceiving of the application E is performed through the modem, and data transceiving of the application F is performed through the BT module. Assume the modem maximum transmit power of the electronic device is Q1 dBm; the BT module of the electronic device has a maximum transmit power of Q2 dBm. A modem of the electronic device presets a first mapping relation between an application service, an uplink duty ratio and a backspacing power. And the BT module of the electronic equipment also presets a second mapping relation between the application service and the uplink duty ratio and the backspacing power.

In the testing stage, data receiving and transmitting are carried out through the modem and the BT module together, and in the limit scene of full uplink transmission, when the actual distance between a user and the electronic equipment is x centimeters (unit: cm), the transmitting power reduction amplitude corresponding to the modem is s1dBm, and the transmitting power reduction amplitude corresponding to the BT module is s2 dBm.

In the actual application service scene, if the distance sensor of the electronic device identifies that the distance from the user to the electronic device is x cm, and the application processor of the electronic device identifies that the current application service scene is an operating application E and an application F, the transceiver module for data transceiving is identified as a modem module and a BT module. And the application processor respectively sends the current application service scene to the modem and the BT module.

And the Modem determines that the uplink occupancy corresponding to the application E is 20% -30% by searching the first mapping relation, and the backoff power corresponding to the uplink occupancy 20% -30% is t 1dBm (t1 is a negative value). The BT module determines that the uplink occupancy corresponding to the application F is 10% to 20% by searching the second mapping relationship, and the backoff power corresponding to the uplink occupancy 10% to 20% is t 2dBm (t2 is a negative value).

The target maximum transmit power of the electronic device modem is adjusted to be s1+ t 1dBm down based on Q1 dBm. That is, the target maximum transmit power of the modem is Q1-s1-t1 dBm. The target maximum emission power of the electronic equipment BT module is adjusted to be reduced by s2+ t 2dBm on the basis of Q2 dBm. That is, the target maximum launch power of the BT module is Q2-s2-t2 dBm.

As can be seen from this example, the modem transmits and receives data to and from the application E, and the BT module transmits and receives data to and from the application F. On the basis of a fixed SAR value reduction scheme, the back-off power which can meet the SAR value requirement is determined through the modem and the BT module according to the uplink ratio of different application services, and the transmitting power is increased.

In the embodiment shown in fig. 5, step S520 is executed to determine the uplink proportion corresponding to the current application service scenario through the transceiver module, and step S530 is executed to determine the back-off power corresponding to the uplink proportion, so as to determine the back-off power.

In other embodiments, steps S520 and S530 may be replaced with: and determining the back-off power corresponding to the current application service scene through the transceiver module.

Different transceiver modules of the electronic device respectively prestore different service scenes and the backspacing power based on the maximum transmitting power, and the mapping relation between the backspacing power and the backspacing power. And searching the backspacing power based on the maximum transmitting power corresponding to the current application service scene according to the mapping relation.

Next, a third application scenario of the method for adjusting transmission power according to the embodiment of the present application is described.

Voice traffic typically uses dedicated bearers. However, the establishment of the dedicated bearer is often accompanied by the establishment of a data bearer. In a third application scenario, consider the case of simultaneous accompanying data traffic in addition to voice traffic. The application scene realizes that the electronic equipment can also improve the transmitting power on the basis of a scheme of fixedly reducing the SAR value under the condition that the voice service is accompanied with the data service, and meets the requirement of the regional SAR value.

Fig. 6 is a flowchart illustrating a method for adjusting transmission power according to an embodiment of the present application. The method of adjusting transmission power is applicable to electronic devices, such as, for example, cell phones. The embodiment shown in fig. 6 adds the case of low-rate data service to that shown in fig. 4, and at this time, the service scenario is still considered as a voice-only service scenario. And determining the backspacing power by searching a mapping relation corresponding to the voice service scene. Accordingly, another way of determining the back-off power is provided. It should be understood that the embodiment of fig. 6 is the same as the embodiment of fig. 4, and the description thereof is omitted here, please refer to the related description of fig. 4. As shown in fig. 6, the method for adjusting the transmission power includes steps S610 to S650. The specific realization principle of each step is as follows:

s610, recognizing the current service scene as a voice service scene.

S620, recognizing the voice system of the voice service scene, and determining the uplink voice packet ratio according to the voice system.

Since the modem (modem processor) can recognize whether the electronic device is conducting voice services. Therefore, in the embodiment of the application, the current service scenario can be identified as the voice service scenario through the modem processor.

And then recognizing the voice system of the voice service scene, and determining the uplink voice packet ratio according to the voice system.

S630, determine whether the service rate of the data service satisfies a preset condition.

The preset condition is satisfied, namely, the low-rate service condition is satisfied. And the modem of the electronic equipment recognizes that the electronic equipment is in a voice service scene, and judges whether the rate of the data service meets a preset condition, wherein the meeting of the preset condition shows that only the data service with low rate exists, namely the service with small data.

If the modem of the electronic equipment identifies that the current scene is a voice service scene and judges that the data service is a low-rate service, determining the backspacing power according to a first higher gear of an uplink proportion corresponding to the current voice service scene, or adjusting the transmitting power according to the backspacing power corresponding to the uplink proportion of the current voice service scene.

Wherein the modem of the electronic device determines that the data traffic is low-rate traffic, including one or more of the following five conditions.

(1) And (5) screen extinguishing of the electronic equipment.

Since the services with high uplink ratio are generally live broadcast or remote operation, the electronic device needs to be on screen at this time. Therefore, when the electronic device is off screen, there may be only some low rate upload traffic. In some embodiments of the present application, it may also be determined whether there is low-rate upload traffic by combining other conditions.

(2) The reported mean value of Buffer Status Report (BSR) is smaller than a first preset threshold.

The first preset threshold is a threshold value set for the BSR reported mean value, and may be an empirical value. The first preset threshold may be preset in the electronic device, or may be set by a user in a self-defined manner. And when the reported mean value of the BSR is smaller than a first preset threshold, indicating that the uplink traffic is not large.

(3) A Packet Data Convergence Protocol (PDCP) uplink Packet size is smaller than a second preset threshold, a Packet loss ratio is smaller than a third preset threshold, and a delay is smaller than a fourth preset threshold.

Wherein, the second preset threshold is a threshold value set for the size of the PDCP uplink packet. The third preset threshold is a threshold value set for the PDCP uplink packet loss rate. The fourth preset threshold is a threshold value set for the PDCP uplink delay. The second preset threshold, the third preset threshold and the fourth preset threshold are empirical values. The three preset thresholds can be preset in an electronic setting or can be set by a user in a self-defined way.

When the size of the uplink packet of the PDCP is smaller than the second preset threshold, the packet loss rate is smaller than the third preset threshold, and the time delay is smaller than the fourth preset threshold, it indicates that the uplink traffic is not large, the retransmission is less, and the uplink occupancy ratio is not high.

(4) An uplink rate of a Medium Access Control (MAC) layer is less than a fifth preset threshold.

Wherein, the fifth preset threshold is a threshold value set for the uplink rate of the MAC layer. The fifth preset threshold is an empirical value. The fifth preset threshold may be preset in an electronic setting or may be set by a user.

And when the uplink rate of the MAC layer is smaller than a fifth preset threshold, the uplink service volume is not large.

(5) The Reference Signal Receiving Power (RSRP) is greater than a sixth predetermined threshold.

Wherein the sixth preset threshold is a threshold value set for RSRP. The sixth preset threshold is an empirical value. The sixth preset threshold may be preset in an electronic setting, or may be set by a user in a self-defined manner.

When the RSRP is greater than the sixth preset threshold, it indicates that the cell signal is better, generally, the RSRP is higher, and the order (or called index value) of the Modulation and Coding Scheme (MCS) is not too low. The same data volume is transmitted, and the transmission can be completed by fewer uplink transmission times.

As a non-limiting example, if one of the above five conditions is satisfied, it is determined that the traffic rate satisfies the preset condition.

For example, a current voice service scene is identified as a voice service scene of a VoLTE system, and an uplink occupation ratio corresponding to the voice service scene of the VoLTE system is 20%. And judging that the service rate meets a preset condition. And determining the back-off power corresponding to the upstream ratio higher than 20% by the first gear (namely, the gear from 20% to 30% in the second table) to be-5.2 dBm by looking up the mapping relation shown in the second table.

In other embodiments of the present application, when the above five conditions are met, it is determined that the traffic rate meets the preset condition. At this time, the data traffic is low rate traffic. The transmitting power can be adjusted according to the back-off power corresponding to the uplink occupation ratio of the current voice service scene.

For example, a current voice service scene is identified as a voice service scene of a VoLTE system, and an uplink occupation ratio corresponding to the voice service scene of the VoLTE system is 20%. And judging that the service rate meets a preset condition. And determining the back-off power corresponding to 20 percent of the uplink occupation ratio to be-7 dBm by looking up the mapping relation shown in the table II.

In other embodiments of the present application, when four of the above five conditions are satisfied, it is determined that the traffic rate satisfies the preset condition. At this time, the data traffic is low rate traffic. The transmitting power of the fixed-reduction SAR scheme can be increased according to the back-off power corresponding to the uplink occupation ratio of the current voice service scene.

It should be understood that the foregoing are merely exemplary descriptions. In some embodiments of the present application, one or more of the five conditions may be selected as the preset condition according to actual situations. In some embodiments of the present application, it may be set to determine the backoff power according to a backoff power corresponding to an uplink duty ratio higher than a first gear, or according to a number of preset conditions.

S650, determining the transmitting power amplitude reduction corresponding to the current man-machine distance, and determining the target transmitting power based on the transmitting power amplitude reduction and the backspacing power.

The back-off power is determined in step S640. Besides determining the backspacing power, the emission power reduction amplitude corresponding to the current man-machine distance is also determined. And then, determining target transmitting power based on the transmitting power amplitude reduction and the backspacing power, thereby realizing the lifting of the transmitting power on the premise of meeting the SAR value requirement. For this part, please refer to the description of the embodiment shown in fig. 4, which is not repeated herein.

It should be understood that, in the embodiment shown in fig. 6, the determining of the transmission power reduction amplitude corresponding to the current man-machine distance in step S650 is only performed before the determining of the target transmission power based on the transmission power reduction amplitude and the back-off power in step S650, and there is no requirement for time sequence between steps S610, S620, S630 and S640.

In the embodiment shown in fig. 6, the modem combines the characteristics of the second packet and the characteristics of turning on and off the screen, etc., to determine the back-off power that can meet the SAR value requirement.

It should be noted that, in the third application scenario, when the current service scenario of the electronic device includes not only a voice service scenario but also a data service scenario.

If the data service satisfies the condition of the low-rate service, the current service scenario of the electronic device can still be analogized to a pure voice service scenario as in the embodiment shown in fig. 6. At this time, the backoff power corresponding to the uplink duty ratio of the first higher rank of the voice format may be determined according to the conditional number of the low-rate service, or the backoff power corresponding to the uplink duty ratio of the voice format may be determined. And then, the target transmission power is determined based on the transmission power of the fixed-reduction SAR scheme under the voice service scene and the backspacing power.

If the modem of the electronic device identifies that the current service scene comprises a voice service scene, the application processor identifies that the current service scene also comprises a data service scene, and the current service scene belongs to the situation of multi-service scene concurrence. The electronic device determines that the data service does not satisfy the condition of the low-rate service, and at this time, the current service scene is not analogized to a pure voice service scene. And determining a transceiver module for currently performing data service transceiving according to the situation of the concurrence of the multiple service scenes, which is similar to the second application scene.

Then, if the transceiving module for performing the data service is also a modem as the same as the voice service scene, the application processor issues the data service which is responsible for transceiving to the modem, and the modem determines an uplink occupation ratio corresponding to the service scene of the combination of the voice service and the data service and determines the back-off power corresponding to the uplink occupation ratio according to the mapping relation of the pre-stored data service scene, the uplink occupation ratio and the back-off power. And then calculates the target maximum transmit power of the modem.

If the transceiving module for performing the data service is not a modem but a WI-FI module or a BT module, on one hand, the modem identifies a voice system of a current voice service scene, determines an uplink occupation ratio corresponding to the voice system, and then determines a back-off power according to the uplink occupation ratio, thereby obtaining a target maximum transmitting power of the modem according to the back-off power. On the other hand, the WI-FI module or the BT module identifies the current data service scene, determines the uplink ratio corresponding to the data service scene, and then determines the back-off power according to the uplink ratio, so that the target maximum transmitting power of the WI-FI module or the BT module is obtained according to the back-off power.

The voice service scenario is concurrent with the data service scenario, and the data service scenario is not a low rate service scenario, which is similar to the second application scenario, please refer to the foregoing description, and details are not repeated here.

The foregoing embodiment shown in fig. 6 considers the case of using the modem to transmit and receive data services, but in practice, there is a case where the module for transmitting and receiving data is not only the modem. For example, data transmission and reception are performed by the WI-FI module and/or the BT module. The difference between data transceiving through the WI-FI module and/or the BT module and data transceiving through the modem is that the condition for determining that the data service is a low-rate service is different. In the following discussion, only the differences from the embodiment of fig. 6 will be described, and the same parts will not be described again.

First, a case of data transmission and reception by the WI-FI module will be described.

Under the condition, the WI-FI module of the electronic equipment judges whether the rate of the data service meets the preset condition, and the meeting of the preset condition indicates that only the data service with low rate exists, namely the service with small data.

The WI-FI module of the electronic device determines that the data service is a low-rate service, and the determination includes one or more of the following three conditions.

(1) And (5) screen extinguishing of the electronic equipment.

(2) An uplink rate of a Medium Access Control (MAC) layer is less than a fifth preset threshold.

(3) The Reference Signal Receiving Power (RSRP) is greater than a sixth predetermined threshold.

It should be understood that, when data is received and transmitted through the WI-FI module, the values of the fifth preset threshold and the sixth preset threshold set may be the same as or different from the values set when data is received and transmitted through the medom. This is not limited by the present application.

The case of data transmission and reception by the BT module will be described.

In this case, the BT module of the electronic device determines whether the rate of the data service satisfies a preset condition, and the satisfaction of the preset condition indicates that only the data service with a low rate, i.e., a service with little data, exists.

The method comprises the following steps that a BT module of the electronic equipment judges that data service is low-rate service, and the method comprises the following conditions.

(1) And (5) screen extinguishing of the electronic equipment.

Finally, a fourth application scenario of the method for adjusting the transmission power according to the embodiment of the present application is described.

In the fourth application scenario, the uplink occupation ratio is not determined according to the service scenario of the electronic device, but the equivalent uplink occupation ratio of the electronic device is calculated in real time. And the back-off power based on the maximum transmitting power is dynamically adjusted according to the equivalent uplink duty ratio, so that a more accurate transmitting power adjusting scheme is realized, and the effect of reducing or not reducing the maximum transmitting power is achieved.

In the first to third application scenarios, the current service scenario is identified, the uplink occupation ratio is determined in a table look-up mode, and then the back-off power based on the maximum transmission power corresponding to the uplink occupation ratio is determined. Finally is calculated at P_{sar_lim}Target transmit power on a base. Wherein, P_{sar_lim}The transmission power of the SAR value reduction scheme is fixed, namely maximum transmission power-transmission power reduction amplitude. Can be represented as P_{sar_lim}And Q-M, wherein Q represents the maximum transmitting power, and M represents the transmitting power reduction amplitude corresponding to the current man-machine distance.

In the fourth application scenario, the uplink occupation ratio is not determined by identifying the service scenario, but the equivalent uplink occupation ratio is calculated in real time, and the back-off power corresponding to the equivalent uplink occupation ratio is determined by table look-up. Finally is calculated at P_{sar_lim}Target transmit power on a base. Target transmission power P_{sar_dec}＝P_{sar_lim}-N, N representing a back-off power. It should be understood that the fourth application scenario may use the mapping relationship between the uplink occupancy ratio and the back-off power in the first to third application scenarios, but replace the uplink occupancy ratio with the equivalent uplink occupancy ratio.

In the fourth application scenario, how to calculate the equivalent uplink share ratio of the electronic device in real time is emphasized. The application scenario is the same as the application scenario described above, and details are not repeated here.

First, windowing is performed in time, with the window length of each time window being t 1. And for each time window, counting the equivalent uplink proportion in the time window.

In some embodiments of the present application, the equivalent uplink share ratio is defined as:

in equation (1), P is the power of each minimum transmission unit in the time window, and Σ P is the sum of the powers of each minimum transmission unit in the time window.

The minimum transmission unit is related to the communication system. In a 2g (gsm) communication system, the minimum transmission unit is one slot, which is about 0.577 ms. In a 3G WCDMA communication system, the minimum transmission unit is one slot, which is about 2 or 3 ms. In 4G or 5G communication systems, the minimum transmission unit is symbol. In a 4G communication system, 14 symbols are contained per ms. In a 5G communication system, each ms contains 1, 2, 4, 8 or 16 slots, each slot containing about 14 symbols.

In equation (1), Ts is the total number of minimum transmission units contained in each time window. P_{sar_lim}The transmission power for a fixed reduced SAR value is equal to the maximum transmission power-transmission power reduction.

in the calculation process, the complexity of the formula (2) is higher than that of the formula (1). However, in one aspect, formula (2) retains the physical meaning of the parameters. On the other hand, formula (2) can be applied to P_{sar_lim}The method has the advantages of better expansibility and stronger environmental adaptability in a changed scene.

The equivalent uplink ratio is the power of the minimum transmitting unit relative to P_{sar_lim}Statistical average of the ratios of (a) to (b).

And then, according to the historical equivalent uplink occupation ratios of the N historical time windows, predicting the equivalent uplink occupation ratio of the current time window. An alpha filtering method may be employed.

y(n)＝y(n-1)·(1-alpha)+x(n)·alpha。 (3)

In the formula (3), y (n) is the filtering result of the current time window; y (n-1) is the filtering result of the previous time window; x (n) is the equivalent uplink ratio of the current time window; alpha is a filtering parameter, and takes a natural number from 0 to 1.

Referring to fig. 7, if the value of the filtering result y (n) of the current time window (or small window) is less than 1, it indicates that the historical transmission power is "not full". That is, on the premise of meeting the requirement of the SAR value region, the transmission power is reduced too much, and the transmission power can be increased if the next time window has a transmission requirement.

If the value of the filtering result y (n) of the current time window is equal to 1, the historical transmitting power just meets the SAR value regional requirement.

If the value of the filtering result y (n) of the current time window is larger than 1, the historical transmitting power exceeds the SAR value regional requirement. The transmit power for the next time window may be adjusted based on the value of y (n).

The equivalent uplink proportion of the current time window is determined by the method, the corresponding backspacing power is determined according to the equivalent uplink proportion, and the power P is calculated according to the backspacing power_{sar_lim}Target transmit power on a base. Target transmission power P_{sar_dec}＝P_{sar_lim}-N, N representing a back-off power. For the above, the detailed description is omitted here.

However, according to regulatory requirements, the SAR value needs to meet regional requirements at any time statistical interval, e.g., 100 seconds. That is, the SAR value cannot exceed the standard from the 1 st second to the 100 th second, and from the 3 rd second to the 103 th second. In order to solve the problem that the statistical interval does not exceed the standard at any time, another embodiment of the fourth application scenario provides the following optimization scheme on the basis of the foregoing embodiment. The optimization scheme may take the following first, second, or combination of first and second.

First, the filtering parameter alpha is selected reasonably.

By properly setting the filtering parameter alpha, the value of y (n) is less than or equal to 1.

Second, reserve power is set.

The reserved power means that a power reduction amplitude SAR _ delta is additionally added on the basis of the fixed SAR reduction amplitude, namely on the basis of the transmission power reduction amplitude.

The additional added power reduction amplitude SAR _ delta may not be set to a too large value and may be 0.1 to 0.4dBm, preferably 0.3 dBm. Reserve power P_reserve＝P_{sar_lim}SAR _ delta, e.g. P_reserve＝P_{sar_lim}-0.3. With continued reference to the reserve power P shown in FIG. 7_reserve。

After setting the power reduction, the power reduction may be translated to a target value for y (n).

As a non-limiting example of the present application, the conversion method is:

for example, substituting SAR _ delta of 0.3dBm into the above equation (4) to obtain 0.9335 means that the target value of y (n) can be adjusted from 1 to 0.9335. If the filtering result y (n) of the current time window is less than 0.9335, the next time window can increase the transmission power; limiting the transmit power of the next time window to P if the filtering result y (n) of the current time window is greater than or equal to 0.9335_reserve。

It should be understood that in other embodiments, the additional increased power reduction amplitude SAR _ delta may also be set to other values. In other embodiments, other equivalent conversion methods may be employed to convert the reserve power to y (n). The numerical value and the conversion method of SAR _ delta are not particularly limited in the embodiment of the present application.

Because extra power amplitude reduction SAR _ delta is preset, after the corresponding back-off power is determined according to the equivalent uplink occupied ratio, the back-off power and the extra power amplitude reduction SAR _ delta are calculated at P_{sar_lim}Target transmit power on a base. Target transmission power P_{sar_dec}＝P_{sar_lim}-N-SAR _ delta, N representing the back-off power. In the embodiment of the application, the extra power reduction amplitude SAR _ delta is preset, so that the SAR value is further prevented from exceeding the standard in any time interval while the transmission power is improved.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
