All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

In the specification and claims, "and/or" indicates at least one of the connected objects, and the character "/" generally indicates that the preceding and following related objects are in an "or" relationship.
The radio frequency signal transmission method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein one electronic device 10 may communicate with another electronic device 20 via radio frequency signals. The electronic device can be but not limited to various smart phones, personal computers, notebook computers, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices can be smart speakers, smart televisions, smart air conditioners, smart vehicle-mounted devices and the like. The portable wearable device can be an intelligent watch, an intelligent bracelet, a head-mounted device and the like.
In one embodiment, the electronic device may include a first radio frequency path and a second radio frequency path, the second radio frequency path being a mirror image of the first radio frequency path, the electronic device being configured to acquire a radio frequency signal, the radio frequency signal including multiple frames of data frames, a frame of data frame including multiple frames of transmission subframes; acquiring the specific absorption rate of a first radio frequency channel in the process of transmitting radio frequency signals through the first radio frequency channel; and under the condition that the specific absorption rate is greater than or equal to a preset specific absorption rate threshold value, keeping the number of data frames transmitted by the first radio frequency path unchanged, and simultaneously allocating partial transmission subframes in each data frame to at least one second radio frequency path for transmission.
Referring to fig. 2, fig. 2 is a flowchart of a radio frequency signal transmission method in an embodiment, where this embodiment exemplifies that the method is applied to an electronic device, the electronic device is provided with at least two radio frequency paths, and at least two of the radio frequency paths have the same structure, and the method specifically includes the following steps:
Wherein the radio frequency signal comprises a plurality of frames of data, each frame of data comprising a plurality of transmit subframes.
In the embodiment of the present application, referring to fig. 3, fig. 3 is a schematic structural diagram of a communication module of an electronic device in an embodiment, where the communication module includes a processor, a radio frequency transceiver, power amplifiers P1 and P2, and antennas T1 and T2. As can be seen, two rf paths are shown, one is a first rf path formed by the processor, the rf transceiver, the power amplifier P1, and the antenna T1, and the other is a second rf path formed by the processor, the rf transceiver, the power amplifier P2, and the antenna T2. The processor is used for obtaining a transmission subframe to be transmitted and processing the transmission subframe; the radio frequency transceiver is used for modulating the transmission sub-frame into a radio frequency signal and sending the radio frequency signal to the power amplifier or acquiring the radio frequency signal received by the antenna; the power amplifier is used for performing power amplification processing on a radio-frequency signal to be transmitted; the antenna is used for outputting radio frequency signals or receiving radio frequency signals.
It should be noted that the second rf path may be a mirror image path corresponding to the first rf path, so that the first rf path and the second rf path have the same structure. Generally, in the case that the electronic device has a basic first rf path, in order to obtain a mirrored second rf path, a radio communication frequency hopping (Tx hopping) technology may be specifically adopted, and the Tx hopping technology may add a front end with the same function and performance to a basic hardware architecture, which is to simply mirror a set of rf paths. In addition, the embodiment of the present application may be specifically applied to a TDD-Long Term Evolution B41 (TDD-LTEB 41, time Division duplex-Long Term Evolution B41) communication architecture, and of course, the embodiment of the present application may also be applied to other communication architectures, which is not limited in this embodiment of the present application.
Further, referring to fig. 4, fig. 4 is a schematic diagram of an rf signal in an embodiment, according to the specification definition of a communication framework, a transmission duration of a complete data frame of a frame is 10ms, a frame of data frame may include 10 subframes, where the 10 subframes include both a transmitting subframe and a receiving subframe, a number of the transmitting subframes is in a range of 1 to 6, and in operation of an electronic device, the number of the transmitting subframes may be dynamically set according to a throughput rate required by communication.
In the embodiment of the application, specific Absorption Rate (SAR) is an important parameter for measuring the electromagnetic radiation amount of the electronic equipment to a living body, the larger the SAR of the electronic equipment is, the larger the electromagnetic radiation amount of the electronic equipment to the outside is, and the higher the current and the heat generated by the electromagnetic radiation amount in the organism tissue are, so that the harm to the physical health of a user of the electronic equipment is larger, so that the safety range of the SAR of the electronic equipment is regulated by a communication standard, and the harm to the physical health of people caused by the electromagnetic radiation amount of the electronic equipment is reduced as much as possible.
SAR represents the amount of radiation that the organism is allowed to absorb per unit kilogram, SAR values represent the effect of the radiation on the human body, and SAR may have data for the whole body, local, extremities. The lower the SAR value, the less the amount of radiation absorbed by the organism, since the SAR is generated in particular by an antenna in the radio frequency path of the electronic device, the SAR of the first radio frequency path may be acquired during the transmission of the radio frequency signal by the first radio frequency path in order to control the SAR of the electronic device.
Specifically, in the process of transmitting a radio frequency signal by the radio frequency path, the SAR of the radio frequency path is directly linked with the heat generated at the position of the radio frequency path, so that the SAR of the radio frequency path can be obtained by detecting the heat generated when the radio frequency path works. In another implementation, the SAR of the radio frequency path may be detected directly using a SAR sensor integrated on the electronic device for detecting SAR size.
And 102, under the condition that the specific absorption rate is greater than or equal to a preset threshold value, keeping the number of frames of data frames transmitted by the first radio frequency channel unchanged, and allocating part of transmission sub-frames in each frame of the data frames to the second radio frequency channel for transmission.
In the embodiment of the present application, in order to ensure safety of electromagnetic radiation of an electronic device to human health, whether an SAR of the electronic device is in a safety range may be determined by setting a preset specific absorption rate threshold, for example, the preset specific absorption rate threshold may be set to 2.0w/kg (10 g) or to 1.6w/kg (1 g), and when a specific absorption rate of a first radio frequency path is greater than or equal to the preset specific absorption rate threshold, it may be considered that the electromagnetic radiation of the electronic device is harmful to the safety of human health, and it is necessary to reduce the SAR of each radio frequency path of the electronic device and the SAR of the whole electronic device by an adjusting means under the condition of ensuring that an overall working power of the electronic device is not changed.
Specifically, the number of frames of the data frame transmitted by the first radio frequency channel may be kept unchanged, so as to ensure that the transmission amount of the entire data is unchanged, and the further radio frequency channel may set a corresponding transmission power for each transmission subframe, where the size of the transmission power affects the transmission duration and the transmission intensity of the transmission subframe, and further affects the transmission distance of the transmission subframe, for example, the larger the transmission power corresponding to the transmission subframe is, the longer the transmission distance of the transmission subframe is.
In the embodiment of the present application, when the specific absorption rate of the first radio frequency path is greater than or equal to the preset specific absorption rate threshold, the number of frames of data frames transmitted by the first radio frequency path may be kept unchanged, and the transmission power of each transmission subframe may also be kept unchanged, and meanwhile, part of the transmission subframes in the data frames may be allocated to at least one second radio frequency path for transmission, so that, under the condition that the overall data transmission amount and the transmission distance of a single transmission subframe are not changed, the transmission subframes included in an original data frame are split and then transmitted by the first radio frequency path and the second radio frequency path, although the first radio frequency path and the second radio frequency path transmit part of the original data frame, respectively, the sum of the first transmission powers of all the transmission subframes only through the first radio frequency path is compared with the sum of the first transmission powers, and the sum of the second transmission powers of the respective transmission part of the transmission subframes through the first radio frequency path and the second radio frequency path is not changed, so that the transmission power of the electronic device is not reduced.
However, in the embodiment of the present application, since the first radio frequency path and the second radio frequency path respectively transmit a part of the transmission subframes in the original data frame, the SAR of the first radio frequency path and the SAR of the second radio frequency path are correspondingly reduced, and based on the structural layout of the electronic device, a certain distance is set between the first radio frequency path and the second radio frequency path in the electronic device, and if there are multiple radio frequency paths, the total SAR of the electronic device is: the product of the sum of the SAR of each radio frequency channel and a distance coefficient (obtained based on the distance between the radio frequency channels and smaller than 1) is obtained, and under the action of the distance coefficient, the total SAR of the electronic equipment is greatly reduced compared with the original value, so that the purpose of reducing the SAR value of the electronic equipment under the condition of ensuring the constant total emission power of the electronic equipment is achieved, and the harm to a human body caused by the radiation of the electronic equipment is reduced on the basis of ensuring the normal use of the electronic equipment.
For example, assuming that a data frame includes 6 transmission subframes, the related art may transmit the 6 transmission subframes in 1 transmission cycle through a first radio frequency path, and in a case where a specific absorption rate of the first radio frequency path is greater than or equal to a preset specific absorption rate threshold, the embodiment of the present application may transmit 3 transmission subframes included in a data frame by the first radio frequency path in 1 transmission cycle, transmit another 3 transmission subframes included in the data frame by a second radio frequency path in 1 transmission cycle, where since a number of frames of the data frame transmitted by the first radio frequency path is kept constant and a transmission power of each transmission subframe is kept constant, a transmission power at which the electronic device transmits the data frame and an overall transmission number of the data frame are not changed, and since the transmission subframes of which are less in number are transmitted by each of the first radio frequency path and the second radio frequency path, respective SAR of the first radio frequency path and the second radio frequency path is halved, according to the overall calculation manner of the electronic device, under an effect of a separation distance between the first radio frequency path and the second radio frequency path, a total SAR of the electronic device is also greatly reduced, thereby ensuring that the electronic device normally radiates the human body.
It should be noted that, in the embodiment of the present application, the number of the selected second radio frequency paths may be adjusted according to actual requirements, and the number of partial transmission subframes allocated to the second radio frequency paths may also be adjusted, which is not limited in this embodiment of the present application.
In summary, the radio frequency signal transmission method provided by the embodiment of the present application includes acquiring a specific absorption rate of a first radio frequency path when a radio frequency signal is transmitted through the first radio frequency path, where the radio frequency signal includes multiple frames of data frames, and each frame of data frame includes multiple transmission subframes; in addition, because the first radio frequency path and the second radio frequency path respectively transmit less sub-frames, the respective specific absorption rates of the first radio frequency path and the second radio frequency path are reduced, and the total specific absorption rate of the electronic equipment is also greatly reduced under the action of the spacing distance between the first radio frequency path and the second radio frequency path, so that the harm of the radiation of the electronic equipment to a human body is reduced on the basis of ensuring the normal use of the electronic equipment.
Optionally, the first radio frequency path and the second radio frequency path are disposed at different positions of the electronic device, and a separation distance between the first radio frequency path and the second radio frequency path is greater than or equal to a preset distance.
Referring to fig. 6 and fig. 6 are schematic structural diagrams of an electronic device in an embodiment, where the electronic device 10 includes a first radio frequency path 11 and a second radio frequency path 12, it can be seen that the first radio frequency path 11 and the second radio frequency path 12 are respectively disposed at two vertex angles of the electronic device 10, and a separation distance between the first radio frequency path 11 and the second radio frequency path 12 is greater than or equal to a preset distance, where the preset distance may be set according to an actual requirement, which is not limited in this embodiment of the present application.
Under such setting, the total SAR of the electronic device is calculated as follows: the product of the sum of the SAR of the first radio frequency path 11 and the SAR of the second radio frequency path 12 and a distance coefficient (obtained based on the separation distance between the SAR of the first radio frequency path 11 and the second radio frequency path 12, which is smaller than 1) is obtained, and under the effect of the distance coefficient, the total SAR of the electronic equipment is greatly reduced compared with the original SAR, so that the purpose of reducing the SAR value of the electronic equipment is achieved under the condition that the total transmission power of the electronic equipment is not changed.
In the embodiment of the application, when the radio frequency channel works, the working power of the radio frequency channel can be calculated based on the collected working voltage and working current of the radio frequency channel.
In the embodiment of the application, in the process of transmitting the radio frequency signal by the radio frequency path, the working power of the radio frequency path has a certain linear corresponding relationship with the SAR of the radio frequency path, so that the SAR corresponding to the radio frequency path under different working powers can be detected by the thermal sensor for detecting the size of the SAR to obtain a preset corresponding relationship between the power and the SAR, and the subsequent electronic equipment can obtain the current SAR value of the first radio frequency path from the corresponding relationship according to the current working power of the first radio frequency path in the electronic equipment.
Specifically, the detection method of the radio frequency path of the electronic device includes: a container containing simulated human tissue fluid is placed below the electronic equipment, a detection probe of the temperature measurement equipment can penetrate into the container, and under the condition that a radio frequency path of the electronic equipment works, the detection probe of the temperature measurement equipment can detect the temperature of the tissue fluid, so that an SAR value is obtained based on temperature calculation.
It should be noted that, the SAR of the radio frequency path may also be detected directly by using a SAR sensor integrated on the electronic device for detecting the SAR size.
In this embodiment, the electronic device includes a first radio frequency path and a plurality of second radio frequency paths, that is, one first radio frequency path forms a plurality of mirror image paths, where the number of paths of the second radio frequency paths is used to characterize the number of paths required for sharing the transmission subframe of the first radio frequency path, and when the specific absorption rate of the first radio frequency path is far greater than the preset specific absorption rate threshold, more second radio frequency paths may be selected to share the transmission subframe.
For example, assuming that the specific absorption rate of one first rf path is 60 and the predetermined threshold value is 13, at least 4 second rf paths are selected so that the specific absorption rate of a single rf path is smaller than the predetermined threshold value.
And 204, determining the average segmentation number of the transmission sub-frames according to the sum of the number of the channels and the number of the transmission sub-frames in the data frame.
In the embodiment of the present application, preferably, all the radio frequency paths formed by the first radio frequency path and the second radio frequency path may equally divide the transmission subframes in the data frame, so that the operating power of each radio frequency path is consistent, and the transmission is kept stable and ordered. It should be noted that, instead of using the averaging scheme, the number of the transmission subframes transmitted by each rf channel may be flexibly adjusted according to actual requirements.
For example, assuming that there are 6 transmission subframes in a data frame, there are a first rf path and a second rf path, and in the case of an averaging scheme, the first rf path and the second rf path can transmit 3 transmission subframes each; in another non-uniform scheme, the first rf path may transmit 2 transmission subframes, and the second rf path may transmit 4 transmission subframes.
Wherein a transmission subframe transmitted by the first radio frequency path is different from a transmission subframe transmitted by the second radio frequency path.
In the embodiment of the present application, after the transmission subframes in the data frame are segmented according to the average segmentation number, the average segmentation number of transmission subframes is respectively allocated to each second radio frequency path and each first radio frequency path for transmission, so that the specific absorption rate of each radio frequency path is reduced, and the total specific absorption rate of the electronic device is also greatly reduced under the effect of the separation distance between the first radio frequency path and the second radio frequency path. Moreover, the frame number of the data frame transmitted by the first radio frequency channel is kept unchanged, and the transmission power of each transmission sub-frame is kept unchanged, so that the transmission power and the transmission data volume of the whole transmission radio frequency signal of the electronic equipment are unchanged, and the communication quality is not influenced.
For example, suppose that the radio frequency path transmits m data frames (such as TDD frames) in a unit time, 1 data frame includes 6 transmission subframes, the transmission power of each transmission subframe is 10dBm, and the transmission period of one data frame is 10ms (6 transmission subframes are to be transmitted within 10 ms).
In view of the above definition, the related art transmits a radio frequency signal through only one radio frequency path, in order to reduce the total SAR value of an electronic device, the number of data frames transmitted per unit time may be kept unchanged, and the transmission period of the data frames is reduced from 10dBm to 5dBm, so that the total SAR value of the electronic device is halved, but the transmission power of the electronic device for transmitting one data frame is also reduced from 60dBm to 30dBm, which may result in halving the transmission distance of the radio frequency signal and seriously affect the communication quality.
With respect to the above definitions, referring to fig. 7, fig. 7 is a schematic diagram of the operation of a communication module of an electronic device in one embodiment; in order to reduce the total SAR value of the electronic device, the embodiment of the present application may keep the number of data frames sent in a unit time, the transmission power of each transmission subframe, and the transmission period of the data frame unchanged, allocate 3 transmission subframes (three transmission subframes U with serial numbers 2, 3, and 4) in 1 data frame to the first radio frequency path T1 for transmission, allocate the remaining 3 transmission subframes (three transmission subframes U with serial numbers 7, 8, and 9) to the second radio frequency path T2 for transmission, and do not perform special processing on the reception subframe D. Thus, the transmission power of the first rf path T1 and the second rf path T2 for transmitting a data frame is reduced from 60dBm to 30dBm, but the transmission power of the electronic device for transmitting a data frame is: the sum (60 dBm) of the transmission power of the first radio frequency path T1 and the transmission power of the second radio frequency path T2 for transmitting one data frame respectively, it can be seen that the transmission power of the electronic device for transmitting one data frame is not reduced by the embodiment of the present application. In addition, the SAR of the first radio frequency channel and the SAR of the second radio frequency channel are reduced by half, and according to the total SAR calculation mode of the electronic equipment, the total SAR of the electronic equipment can be greatly reduced under the action of the spacing distance between the first radio frequency channel and the second radio frequency channel, so that the harm of the radiation of the electronic equipment to a human body is reduced on the basis of ensuring the normal use of the electronic equipment.
Optionally, step 205 may specifically include:
sub-step 2051, obtaining a sequence of frames consisting of transmission subframes in said data frame.
