Description

Method and device for controlling transmission power, computer equipment and storage medium

Technical Field

The present disclosure relates to the field of mobile terminal technologies, and in particular, to a method and an apparatus for controlling transmit power, a computer device, and a storage medium.

Background

Electromagnetic radiation of mobile terminal devices such as mobile phones, smart watches, and computers may affect human safety. Particularly, with the coming commercialization of the New 5G air interface (NR), a terminal supporting high-frequency band high power will become the mainstream of the market, and this also objectively increases the risk of the electromagnetic radiation of the terminal to be safe to the human body.

The electromagnetic radiation standard for the safety of a terminal to a human body is internationally expressed by an electromagnetic wave Absorption ratio or Specific Absorption Rate (SAR) and a Maximum allowable Exposure (MPE). The former is mainly aimed at low frequency bands, such as the bands below 6 GHz. While the latter is primarily directed to the millimeter wave band.

In the standard specification of 3GPP, in order to reduce the impact of terminal transmission on human body safety, a power backoff or an uplink duty cycle reduction is defined. In one embodiment, the terminal detects whether a human body is close to the terminal through a sensor to determine whether to reduce power or reduce the transmission duty cycle to roughly determine whether to reduce power. This method is very effective for the terminal to transmit at low frequencies (e.g., below 6 GHz) meeting specific absorption rate SAR requirements. For millimeter waves, although a terminal can judge that a human body is nearby by a sensor detection mode, the millimeter wave frequency band has the characteristics of narrow wave beam, concentrated radiation energy and the like, the method cannot accurately detect and judge whether power needs to be reduced or emission duty ratio needs to be reduced, and influence caused by electromagnetic radiation of the terminal cannot be effectively reduced while communication quality is ensured.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

First, for convenience of understanding any embodiment of the present disclosure, an application scenario of reducing the transmission power of a transmission beam of a handset is described by an embodiment.

In one embodiment, in order to reduce the radiation effect of the beam emitted by the mobile phone on human body safety, a power back-off or an uplink duty cycle reduction is generally adopted. Referring to fig. 1, the mobile phone detects whether a human body is close to the mobile phone (when the distance d is smaller than a set threshold, it is determined that the human body is close to the mobile phone) through a sensor to determine whether to reduce power or reduce a transmission duty ratio, or roughly determine whether to reduce power according to a service type, a service scene, and other manners. For example, when the handset uses voice service, is not hands-free, and is not plugged into a headset, the handset needs to reduce power and limit transmission power. The method is very effective for meeting the requirement of electromagnetic wave energy Absorption ratio (SAR) when the low frequency, such as a mobile phone transmits a wave beam below 6 GHz. However, this method is not suitable for the millimeter wave band, mainly because of the millimeter wave band. Because the wave beam is narrow and the radiation energy is concentrated, although the mobile phone judges that the human body is nearby through a sensor or a use scene, if the transmitted wave beam does not face the human body, the mobile phone is still safe for the human body, and the transmission power of the terminal is not limited. And the communication quality of the handset is affected if the transmission power is limited.

Fig. 2 is a flowchart illustrating a method for controlling transmission power according to an exemplary embodiment, where the method is used in a terminal, as shown in fig. 2, and includes the following steps:

step 21, transmitting the beam.

Here, the terminal may be a mobile phone, a tablet computer, an intelligent bracelet, an intelligent watch, a vehicle-mounted terminal, or the like;

in one embodiment, the terminal may transmit a beam to space centered at a certain transmission point. Referring to fig. 3, the terminal transmits a beam to a space centering on a transmission point o, where the beam includes 6 beams of T1, T2, T3, T4, T5, and T6. Here, each beam corresponds to a beam direction and a radiation region in space. Here, the transmission point may be a position of a transmission antenna of the terminal. Here, the direction of each beam may be determined according to the position of the transmitting antenna of the terminal. In one embodiment, the terminal transmits beams according to a schedule of a base station.

And step 22, when the beam transmitted by the terminal is a first type beam facing to a human body area, reducing the transmission power of the first type beam by adopting power limitation meeting the human body safety requirement.

In one embodiment, the human body region is a region where a human body of a user using the terminal is located.

Illustratively, the human body region may be a spatial region occupied by a human body in a space. In one embodiment, referring to fig. 4, the body region may be a spatial region formed by the front contour of the body and the beam emitting point o in space. In one embodiment, the human body region may change following the change of the posture, position, etc. of the human body.

In one embodiment, meeting human safety requirements may be a Maximum allowable Exposure (MPE) of the transmitted beam being within a set range. Here, the power limitation may be power backoff or reduction of an uplink duty cycle when transmitting the beam.

In one embodiment, the transmitted beam is directed towards a body region where the radiation area of the beam overlaps with the body region. In one embodiment, when a part or all of a radiation area of a beam transmitted by the terminal is included in the body area, the beam is determined to be a first type beam toward the body area.

In the embodiment of the present disclosure, when the beam transmitted by the terminal is a first type beam facing a human body region, the transmit power of the first type beam is reduced by using power limitation that meets the human body safety requirement, and the transmit power of the first type beam is reduced by using power limitation that meets the human body safety requirement. At this time, the power of the first type beam is transmitted at a transmission power level reduced to a transmission power harmless to the human body or within a range of a degree of harm accepted according to a predetermined standard. Thus, when the beam transmitted from the terminal is directed toward the body region, the transmission power of the beam is reduced. By reducing the transmitting power of the wave beams in the human body area, the influence of the electromagnetic radiation of the wave beams on the human body safety can be reduced, and the safety requirement of the human body is met. Meanwhile, the mode of reducing the beam transmitting power is adopted for relatively not distinguishing the human body area, so that the communication of the terminal is more stable, and the communication quality is improved. Fig. 5 is a flowchart illustrating a method of controlling transmission power according to another exemplary embodiment, the method further including the steps of, as shown in fig. 5:

and step 51, when the beam transmitted by the terminal is a second type beam facing to a non-human body area, reducing the transmission power of the second type beam without adopting the power limitation.

In one embodiment, the non-human body region is a region outside the human body region. The radiation area of the second type of beam does not contain the body region.

In one embodiment, the transmitted beam is directed towards a non-body region may be a region where the radiation area of the beam does not overlap with the body region. In one embodiment, when a radiation area of a beam transmitted by the terminal is not included in the human body area, it is determined that the beam is a second beam directed toward the non-human body area.

Here, when the beam transmitted by the terminal is a second type beam directed to a non-human body region, the second type beam does not radiate a human body and does not affect human body safety, and the transmission power of the second type beam may not be reduced by using the power limitation, so that the communication quality is more stable.

Fig. 6 is a flowchart illustrating a method of controlling transmission power according to another exemplary embodiment, the method further including the steps of, as shown in fig. 6:

and step 61, determining the human body area covering the human body according to the distance between the terminal and the human body.

In an embodiment, referring to fig. 7, if the distance between the terminal and the human body is D, the body width of the human body is W, and the height of the human body is H, the human body area may be determined according to D, W, and H. In one embodiment, angle λ may be determined from said D and said W. In one embodiment, the area irradiated by the angle λ is the human body area. In one embodiment, the terminal calculates the angle λ according to the distance D between the human body and the terminal measured by the sensor and the width data W of the human body region. In one embodiment, a beam is a first type beam if the radiation area of the beam overlaps with the angle λ, and is a second type beam otherwise.

Fig. 8 is a flowchart illustrating a method of controlling transmission power according to another exemplary embodiment, which further includes the steps of, as shown in fig. 8:

and 81, predicting the distance between the terminal and the human body according to the use scene of the terminal and/or the transmitted service data.

In one embodiment, a usage scenario of a terminal may be determined by determining whether a function of the terminal is turned on. For example, when a voice service function of a terminal is turned on, a hands-free function is not turned on, and an earphone function is not turned on, it is predicted that a distance between the terminal and the human body is 1 cm.

In one embodiment, the distance between the terminal and the human body may be predicted by determining the type of traffic data transmitted by the terminal. For example, when the service data transmitted by the terminal is video data, the distance between the terminal and the human body is predicted to be 40 cm. And when the service data transmitted by the terminal is voice data, predicting that the distance between the terminal and the human body is 1 cm.

In one embodiment, please refer to table one, a corresponding relationship between a usage scenario of the terminal and a prediction of a distance between the terminal and the human body may be established in advance; or, please refer to table two, a corresponding relationship between the service data transmitted by the terminal and the distance between the predicted terminal and the human body may be established in advance. When the using scene and/or the transmitted service data of the terminal are determined, the distance between the terminal and the human body can be quickly predicted.

Fig. 9 is a flowchart illustrating a method of controlling transmission power according to another exemplary embodiment, and as shown in fig. 9, the method further includes the steps of:

step 91, generating a first beam list including the first type of beams and generating a second beam list including the second type of beams according to the radiation direction of the beams and the human body area.

In an embodiment, referring to fig. 10, a radiation plane of a beam that can be supported by a terminal may be a plane that takes an antenna emission point of the terminal as a radiation origin point, passes through the origin point, and is perpendicular to a mobile phone screen. In one embodiment, the terminal is capable of transmitting 12 beams identified as T1 to T12. As shown in fig. 10, since the radiation areas of the beams T6 and T7 cover the human body area, the radiation areas of the beams T1 to T5 and T8 to T12 do not cover the human body area. Thus, beams T6 and T7 are beams of the first type; the beams T1 to T5 and T8 to T12 are beams of the second type. Table three shows a first beam list; table four shows the second beam list. It should be noted that the first beam list and the second beam list may further include some auxiliary information. For example, angle information of beam radiation.

In one embodiment, the first beam list and the second beam list may be stored in a terminal.

And step 92, determining that the beam transmitted by the terminal is the first type beam or the second type beam according to the first beam list and the second beam list.

In one embodiment, when the base station schedules the terminal to transmit a beam, whether the transmitted beam is the first type beam or the second type beam can be queried through a beam list according to the identification of the transmitted beam. For example, when the base station schedules the terminal to transmit the beam T6, it is determined that the transmitted beam is the first type of beam by looking up the first beam list in table three, that is, T6 is the beam facing the human body region.

Fig. 11 is a flowchart illustrating a method for controlling transmission power according to another exemplary embodiment, where, as shown in fig. 11, the determining the human body region covering the human body according to the distance between the terminal and the human body in step 61 includes:

and step 111, when the relative position change value between the terminal and the human body is larger than a set threshold value, re-determining the human body area based on the distance between the terminal and the human body.

In one embodiment, the relative position change between the terminal and the human body may be a change in distance therebetween.

In another embodiment, the change in the relative position between the terminal and the human body may also be a change in the orientation of the human body relative to the terminal. For example, the human body moves from a southeast direction of the terminal to a southwest direction of the terminal.

In one embodiment, when the initial transmission power of the terminal is greater than a first power threshold, a set threshold less than a second power threshold may be set; when the initial transmission power of the terminal is less than the third power threshold, a setting threshold greater than the fourth power threshold may be set. Therefore, different setting thresholds can be determined according to different degrees of the influence of the initial transmitting power of the terminal on the safety of the human body, the transmitting power can be accurately controlled, and the radiation risk of the wave beam to the human body can be reduced.

In order to better understand the technical scheme of the present disclosure, the technical scheme of the present disclosure is further explained by two examples below.

Example 1:

the method comprises the following steps:

step a1, when the beam emitted by the terminal is a first type beam facing a human body area, adopting power limitation meeting human body safety requirements, and reducing the emission power of the first type beam.

Referring to fig. 12, since the front surface of the terminal (the plane of the terminal screen) generally faces the human body area during normal use of the terminal, the front surface of the terminal is selected as a reference surface in this example. The terminal may determine the total width of all active beams supported by the terminal based on design and testing. For example, the beams supported by the terminal for transmission are identified as identifier 1 (index 1) to identifier N (indexN), the maximum angle occupied by all beams is a, and the maximum angle occupied by the beams on the front surface of the terminal is b. Here, referring to fig. 7 again, the terminal calculates the angle λ according to the distance D between the human body and the terminal measured by the sensor and the width data W of the human body. The present example is directed to a case where the maximum angle b does not completely include the angle λ, and the angle may use the geometric center of the terminal as the center reference point, or may use the antenna position as the center reference point according to the actual situation of the terminal. The terminal may divide the beam of the terminal into a safe beam zone and a dangerous beam zone according to three angles a, b, and λ, as shown in fig. 12. The terminal divides a safe beam area and a dangerous beam area according to an interface B, namely one edge of an angle lambda:

safe beam area: the wave beam is positioned in the area of one side of the interface B, which is far away from the human body;

danger beam area: the beam is located in the region on the side of the boundary plane B close to the human body.

In another embodiment, the interface may also be roughly selected as interface B', such as:

safe beam area: the wave beam is positioned in the area of one side of the interface B' far away from the human body;

danger beam area: the beam is located in the region on the side of the boundary plane B' close to the human body.

Here, when the beam transmitted from the terminal is directed toward the dangerous beam zone, it is determined that the beam transmitted from the terminal is directed toward a human body region.

Here, when the transmitted beam overlaps with the dangerous beam zone, it may be determined that the transmitted beam is a first type beam directed toward the human body region. When the transmitted beam does not overlap the danger beam zone, the transmitted beam can be determined to be a second type of beam directed toward a non-human body area. In one embodiment, the terminal may establish a first beam list marked with a dangerous beam zone or a second beam list marked with a safe beam zone, and establish a correspondence between the beam identifier and the dangerous beam zone or the safe beam zone through the first beam list and the second beam list. The information of the first beam list and the second beam list can be reported to a base station.

It should be noted that the division of the safe beam area and the dangerous beam area is not fixed, and may be changed according to the distance change of the terminal relative to the terminal when the terminal detects the human body. In one embodiment, when the distance change exceeds a first set threshold, the terminal re-divides the safe beam area and the dangerous beam area; or, when the angle lambda changes to exceed a second set threshold, the safe beam zone and the dangerous beam zone are subdivided.

Step b1, when the beam transmitted by the terminal is a second type beam facing to a non-human body area, the transmission power of the second type beam is not reduced by adopting the power limitation.

Here, when the beam transmitted by the terminal is directed toward the safe beam area, it is determined that the beam transmitted by the terminal is directed toward a non-human body area.

Example 2:

the method comprises the following steps:

step a2, when the wave beam emitted by the terminal is a first type of wave beam facing to a human body area, adopting power limitation meeting the human body safety requirement, and reducing the emission power of the first type of wave beam.

Referring to fig. 13, the front surface of the terminal is selected as the reference surface in this example. The terminal may determine the total width of all active beams supported by the terminal according to design and testing. For example, the beams supported by the terminal to be transmitted are identifier 1 (index 1) to identifier N (indexN), the maximum angle occupied by all beams is a, and the maximum angle occupied by the beams on the front surface of the terminal is b. Here, referring to fig. 7 again, the terminal calculates the angle λ according to the distance D between the human body and the terminal measured by the sensor and the width data W of the human body. The present example is directed to a case where the maximum angle b does not completely include the angle λ, and the angle may use the geometric center of the terminal as the center reference point, or may use the antenna position as the center reference point according to the actual situation of the terminal. The terminal may divide the beam of the terminal into a safe beam area and a dangerous beam area according to three angles a, b, and λ, as shown in fig. 11. As shown in fig. 13. The terminal divides a safe beam area and a dangerous beam area according to an interface B, namely two edges of an angle lambda:

safe beam area: the beam is located in the area within the interface B;

the danger beam area is as follows: the beam is located in a region outside the interface B.

In another embodiment, the interface can also be roughly selected as interface B', two sides of the angle B, dividing the safe beam zone and the dangerous beam zone:

safe beam area: the beam is located in the region within the boundary plane B';

the danger beam area is as follows: the beam is located in a region outside the boundary plane B'.

Here, when the transmitted beam overlaps with the dangerous beam zone, it may be determined that the transmitted beam is a first type beam directed toward the human body region. When the transmitted beam does not overlap with the dangerous beam zone, the transmitted beam can be determined to be a second type beam towards a non-human body area. In one embodiment, the terminal may establish a first beam list marked with a dangerous beam zone or a second beam list marked with a safe beam zone, and establish a correspondence relationship between the beam identifier and the dangerous beam zone and the safe beam zone through the first beam list and the second beam list. The information of the first beam list and the second beam list can be reported to a base station.

And b2, when the beam transmitted by the terminal is a second type beam facing to a non-human body area, reducing the transmission power of the second type beam without adopting the power limitation.

Here, when the beam transmitted by the terminal is directed toward the safe beam region, it is determined that the beam transmitted by the terminal is directed toward a non-human body region.
