Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for adjusting a working mode of a terminal device, and a storage medium.
Background
With the rapid development of the technology, people have higher and higher requirements on data transmission rate, and a fifth generation mobile communication technology (5G for short) is produced. The 5G operates in a higher frequency band, providing a larger available bandwidth. At the initial stage of operation, 5G will work in a Non-Stand Alone one (NSA) mode, that is, a dual connection mode of Long Term Evolution (LTE) and New Radio (NR), so that there may be two, three or more uplink transmissions working simultaneously.
In the 5G NR and LTE deployments, the uplink transmission power of a terminal device (UE) is classified by a power class. According to the definition of the 3rd generation partnership Project (3 GPP) protocol, the power class supported by the conventional mobile phone ue is powerclass 3, and the corresponding output power is about 23 dBm. In some application scenarios, for example, when the UE operates in a higher frequency band such as 3.5GHz, in order to improve coverage problems caused by uplink and downlink imbalance in the high frequency band, the UE needs to have a higher uplink transmission power, for example, 26dBm (corresponding to power class 2). The coverage area of the time division long term evolution TDD LTE band 41 can be increased by 30% from the 3dB increase in LTE UE transmit power. Therefore, it is important to increase the transmit power of the UE.
Generally, the mode in which a High Power terminal equipment (HPUE) operates is a High Power mode. Regarding the high power mode, the 5G NR system follows the LTE system method, and ranks the transmission power of the UE, where power class 2 corresponding to the transmission power of 26dBm represents one high power mode, and power class 1 and power class 0 represent two high power modes with higher transmission power.
In different high power modes of HPUE, there is a difference between the data transmission Rate of the UE and the Specific Absorption Rate (SAR) value of the radiation level to the human body. How to deal with the relationship between electromagnetic radiation and data transmission rate during the operation of HPUE is a matter that needs to be considered by researchers.

According to the method for adjusting the working mode of the terminal equipment, provided by the embodiment of the invention, the terminal equipment is adjusted to work in a proper high-power mode according to the distance by utilizing the distance between the terminal equipment and the human body, so that the electromagnetic radiation and the data transmission rate of the terminal equipment are balanced, and the higher data transmission rate is realized under the condition of reducing the electromagnetic radiation on the human body.
The following describes in detail an implementation of the method for adjusting the operating mode of the terminal device according to the embodiment of the present invention, in conjunction with an application scenario of the terminal device including three transmitting antennas.
Fig. 2 is a schematic structural diagram of a terminal device according to an embodiment of the present invention. As shown in fig. 2, the terminal device includes a baseband processor BP, a 5G radio frequency transceiver TS1, a 5G amplifier PA1, a 5G amplifier PA2, a 5G filter F1, a 5G filter F2, a 5G switch S1, a 5G switch S2, a 4G radio frequency transceiver TS2, a 4G amplifier PA3, a 4G filter F3, a 4G switch S3, a distance sensor D, a 5G antenna Tx1, a 5G antenna Tx2, and a 4G antenna Tx 3.
The distance sensor D is used for detecting the distance between the terminal equipment and the human body and sending the detected distance to the baseband processor BP.
The baseband processor BP is responsible for processing communication data and controlling the working state of devices in the radio frequency channel according to the interaction information with the network.
The 5G rf transceiver TS1 and the 4G rf transceiver TS2 are both configured to modulate and demodulate rf signals, and modulate low-frequency signals into high-frequency signals for output.
The 5G amplifier PA1, the 5G amplifier PA2, and the 4G amplifier PA3 are all configured to amplify power of a radio frequency signal. Moreover, the 5G amplifier PA1, the 5G amplifier PA2 and the 4G amplifier PA3 all support HPUE, and the maximum power of the radio-frequency signals at the output port of the antenna can reach 26 dBm.
The 5G filter F1, the 5G filter F2 and the 4G filter F3 are all used for filtering out-of-radio-frequency-band signals and reducing interference.
The 5G switch S1, the 5G switch S2 and the 4G switch S3 are used for switching a transmitting path and a receiving path, for switching a current-band path and other-band paths, or for switching the current-band path and a standard path.
The 5G antenna Tx1, the 5G antenna Tx2 and the 4G antenna Tx3 are all used to convert the conducted rf signal into an electromagnetic wave signal for radiation, or to receive an external electromagnetic wave signal and transmit the electromagnetic wave signal to an rf transceiver for conversion.
It can be seen that the terminal device in fig. 2 supports non-independent networking of LTE +5G NR, and transmits signals through the 5G antenna Tx1, the 5G antenna Tx2, and the 4G antenna Tx3 three-way antenna. The independent network is a newly-built network, and comprises a new base station, a backhaul link and a core network. Non-independent networking will deploy 5G small base stations in high traffic density areas with the help of existing 4G infrastructure.
The following describes in detail an implementation process for adjusting the operation mode of the terminal device shown in fig. 2 by using an embodiment of the present invention, with reference to fig. 3.
Before starting the adjustment, the following preparation work needs to be completed. Firstly, the data transmission rate and the SAR value of the terminal equipment are respectively tested under a plurality of high-power modes, and the measurement result of the data transmission rate and the measurement result of the SAR value under each high-power mode are stored. Wherein each high power mode is characterized by a transmit power combination of 5G antenna Tx1, 5G antenna Tx2, and 4G antenna Tx 3. The Total Radiated Power (TRP) of the terminal device is the same in each high power mode. And the total radiated power of the terminal device in each high power mode is greater than or equal to 26 dBm. And obtaining the total radiation power of the terminal equipment in each high-power mode according to the transmission power of each antenna in the terminal equipment.
As an example, fig. 4 shows the transmission power of three antennas of the terminal device in three operation modes when the total radiated power of the terminal device is an effect of 26dBm (decibel-milliwatt). Wherein each operating mode is a high power mode. Specifically, in high power mode 1, the transmit power of 5G antenna Tx1 and 5G antenna Tx2 are both-40 dBm, and the transmit power of 4G antenna Tx3 is 26 dBm. In high power mode 2, the transmit power of 5G antenna Tx1 is 23dBm, the transmit power of 5G antenna Tx2 is-40 dBm, and the transmit power of 4G antenna Tx3 is 23 dBm. In the high power mode 3, the transmission power of the 5G antenna Tx1 is 20dBm, the transmission power of the 5G antenna Tx2 is 20dBm, and the transmission power of the 4G antenna Tx3 is 23 dBm.
That is, high power mode 1 is characterized by a transmit power combination of 26dBm, -40dBm, and-40 dBm. High power mode 2 is characterized by a combination of transmit powers of 23dBm, and-40 dBm. High power mode 3 is characterized by a combination of transmit powers of 23dBm, 20dBm, and 20 dBm. In each high power mode, the total radiated power of the terminal device is 26 dBm.
Under the three high power modes, the data transmission rate and the SAR value of each high power mode are tested in advance, and the measurement results are stored in a state list, wherein the data transmission rate of the terminal device under each high power mode and the SAR value of the terminal device under each high power mode are stored in the state list, which is detailed in table 1 below.
TABLE 1
In table 1, only three high power modes are listed, and if there are other high power modes that can make the total transmission power of the terminal device be 26dBm, the data transmission rate and the SAR value of the terminal device in other high power modes may also be measured in advance, and the measured data transmission rate and SAR value of the terminal device are stored in table 1.
In the embodiment of the present invention, the status list not only includes the data transmission rate and the SAR value of the terminal device in each high power mode, but also includes a table for characterizing the transmission power corresponding to three antennas in the terminal device in each high power mode, so as to adjust the high power mode of the terminal device.
The transmitting power information of the terminal equipment antenna in each high-power mode is different, but the total radiation power of the terminal equipment is 26 dBm. In each high power mode, the data transmission rate of the terminal device is different, and the SAR value of each terminal device is also different.
The data transmission rate and the SAR value of the terminal equipment in a plurality of working modes are measured in advance, and the distance between the terminal equipment and a human body is utilized to adjust the terminal equipment to the proper working mode, so that the balance of the data transmission rate and the SAR value of the terminal equipment in a high-power mode is realized.
After obtaining the state list of each operation mode, data transmission rate and SAR value tested in advance, the state list may be stored in the terminal device.
The method for adjusting the working mode of the terminal equipment provided by the embodiment of the invention is used for adjusting the high-power mode of the terminal equipment, so that the terminal equipment needs to be determined to enter the high-power mode state for transmitting.
As an example, the terminal device monitors the total radiation power of itself in real time, and determines whether itself operates in the high power mode by using the total radiation power. As an example, if the terminal device determines that its total radiation power is greater than or equal to 26dBm, it may determine that it is operating in the high power mode.
And if the terminal equipment determines that the terminal equipment does not work in the high-power mode, the terminal equipment does not process the data. If the terminal equipment determines that the terminal equipment works in the high-power mode, the distance between the terminal equipment and the human body, namely the detection value of the distance sensor, is obtained from the distance sensor, and the working mode of the terminal equipment is adjusted according to the distance.
In an embodiment of the present invention, the distance sensor may be an infrared sensor or another type of distance sensor, which is not limited herein. The distance between the terminal device and the human body can be the distance between the terminal device and the designated part of the human body, and the designated part of the human body can be determined according to the actual application scene. As an example, when the user makes a long-time voice call with the terminal device, the designated part of the human body may be an ear of the human body, that is, the distance between the terminal device and the human body may be the distance between the terminal device and the ear.
In the embodiment of the invention, when the distance between the terminal equipment and the human body is less than or equal to the preset first distance, the working mode of the terminal equipment is adjusted to the first high-power mode. And when the distance between the terminal equipment and the human body is greater than the preset second distance, adjusting the working mode of the terminal equipment to a second high-power mode.
And the SAR value of the terminal equipment in the first high-power mode is smaller than that of the terminal equipment in the second high-power mode. The data transmission rate of the terminal device in the first high power mode is smaller than the data transmission rate of the terminal device in the second high power mode.
When the distance between the terminal device and the human body is smaller than the first distance, the harm of the electromagnetic radiation of the terminal device to the human body is possibly large, the working mode of the terminal device is adjusted to the first high-power mode with the small SAR value, and the harm of the electromagnetic radiation of the terminal device to the human body when the distance between the terminal device and the human body is too close is avoided.
When the distance between the terminal device and the human body is greater than the second distance, the harm of the electromagnetic radiation of the terminal device to the human body is relatively small, the data transmission rate of the terminal device can be considered preferentially, and the working mode of the terminal device is adjusted to a second high-power mode with a relatively high data transmission rate, so that the data transmission performance of the terminal device is ensured.
The distance between the terminal equipment and the human body is utilized to balance the electromagnetic radiation and the data transmission rate of the terminal equipment, so that the terminal equipment works in a proper high-power mode.
In some examples, to reduce the harm of the electromagnetic radiation of the terminal device to the human body, the first high power mode may be selected using a preset SAR threshold. For example, the SAR value of the terminal device in the first high power mode is smaller than a preset SAR threshold. If the number of the high power modes with the SAR values smaller than the preset SAR threshold is greater than or equal to 2 in the at least two high power modes, any one high power mode with the SAR value smaller than the preset SAR threshold can be used as the first high power mode. The preset SAR threshold may be determined according to an actual application scenario, and is not limited herein.
In other examples, in order to more effectively reduce the harm of the electromagnetic radiation of the terminal device to the human body, the high-power mode with the smallest SAR value of the at least two high-power modes may be used as the first high-power mode. That is, the terminal device has a smaller SAR value in the first high power mode than in the remaining operating modes.
As a specific example, if the SAR value corresponding to the high power mode 1 is minimum in the at least two high power modes of table 1, the operation mode of the terminal device is adjusted to the high power mode 1. Specifically, the transmission power of each of the 5G antenna Tx1 and the 5G antenna Tx2 of the terminal device is adjusted to-40 dBm, and the transmission power of the 4G antenna Tx3 is adjusted to 26dBm, so that the three antennas of the terminal device transmit signals at the transmission powers, respectively.
In some examples, to ensure data transmission performance of the terminal device, the second high power mode may be selected according to a preset data transmission rate threshold. For example, the data transmission rate of the terminal device in the second high power mode is greater than the preset data transmission rate threshold. And if the number of the high-power modes with the data transmission rate larger than the preset data transmission rate threshold value in the at least two high-power modes is larger than or equal to 2, taking any one high-power mode with the data transmission rate larger than the preset data transmission rate threshold value as a second high-power mode.
In other examples, in order to enable the terminal device to have a higher data transmission rate in a case where the human body is less harmful to electromagnetic radiation, the high power mode having the highest data transmission rate of the at least two high power modes may be used as the second high power mode. That is, the data transmission rate of the terminal device in the second high power mode is greater than the data transmission rate in the remaining operating modes.
In some embodiments of the present invention, the first distance is greater than or equal to 0.1 cm and less than or equal to 50 cm. The first distance may be set according to a specific terminal device model and an actual application requirement.
In some embodiments of the present invention, if the first distance is smaller than the second distance, when the distance between the terminal device and the human body is greater than the first distance and smaller than or equal to the second distance, the operation mode of the terminal device is adjusted to the third high power mode.
The SAR value of the terminal equipment in the first high-power mode is smaller than that of the terminal equipment in the third high-power mode, and the SAR value of the terminal equipment in the third high-power mode is smaller than that of the terminal equipment in the second high-power mode.
The data transmission rate of the terminal device in the first high power mode is smaller than the data transmission rate of the terminal device in the third high power mode, and the data transmission rate of the terminal device in the third high power mode is smaller than the data transmission rate of the terminal device in the second high power mode.
When the distance between the terminal equipment and the human body is greater than the first distance and less than or equal to the second distance, the working mode of the terminal equipment is adjusted to the third high-power mode, so that the terminal equipment can have relatively proper data transmission rate on the basis of avoiding the harm of the electromagnetic radiation of the human body to the terminal equipment, and the balance between the data transmission rate and the SAR value is achieved. And, the high power mode of the terminal device can also be adjusted more flexibly.
In some examples, the first distance may be equal to the second distance. As a specific example, when the first distance is equal to the second distance, referring to fig. 3, if the distance between the terminal device and the human body is less than or equal to the first distance, the high power mode with the minimum SAR value in table 1 is used as the current operating mode of the terminal device, so as to reduce the electromagnetic radiation of the terminal device to the human body. If the distance between the terminal equipment and the human body is greater than the first distance, the high-power mode with the highest data transmission rate in the table 1 is used as the current working mode of the terminal equipment, so that the transmission performance of the terminal equipment is ensured. If the first distance is equal to the second distance, the data processing speed can be increased, and therefore the adjustment efficiency of the working mode of the terminal equipment is improved.
According to the method for adjusting the working mode of the terminal equipment, which is provided by the embodiment of the invention, the proper high-power mode is determined from the plurality of high-power modes as the current working mode of the terminal equipment according to the distance between the terminal equipment and the human body, the first distance and the second distance so as to achieve the balance between the data transmission rate and the radiation SAR value.
Moreover, by adjusting the working mode of the terminal device, the transmission power of the transmitting antenna included in the terminal device is adjusted, so that the power control of the 5G terminal device under the non-independent networking is realized.
In the embodiment of the invention, the terminal equipment comprises at least three transmitting antennas and supports non-independent networking. The high power mode is characterized by a combination of transmit powers of at least three transmit antennas of the terminal device. That is to say, the terminal device that includes more than three transmitting antennas and supports non-independent networking is all applicable to the method for adjusting the operating mode of the terminal device provided by the embodiment of the present invention. Therefore, the method for adjusting the working mode of the terminal equipment, provided by the embodiment of the invention, is suitable for various terminal equipment and has a wide application range.
