With the continuous development and enrichment of terminal services (such as live video services, game services, etc.), people's demand for wireless communication is also increasing, which also leads to the continuous increase of energy consumption in the communication process. However, the power consumption of the terminal is limited by the battery capacity.

In the wireless communication process, the energy consumption of the terminal is mainly composed of the circuit loss of the baseband signal processing process and the signal transmission energy consumption.

In order to facilitate the understanding of this application, the relevant technical knowledge involved in the embodiments of this application is first introduced here.

This application proposes an energy-saving antenna selection method suitable for 5G NR terminals. The terminal can select a suitable method according to the user information of the UE (the service characteristics of the UE, the quality of the air interface channel) and the characteristic relationship between the total power consumption of the power amplifier module and the output power. The uplink antenna is designed to achieve terminal energy saving without affecting the user experience. Among them, the power amplifier module may also be referred to as a radio frequency module, and the characteristic relationship between the total power consumption of the power amplifier module and the output power may also be referred to as the characteristic relationship between the total power consumption of the radio frequency and the radio frequency output power. This application uses the existing terminal transmission mechanism to perform a simple upgrade and transformation, collects the radio frequency data of each antenna in real time, and estimates its characteristics, combines the uplink channel estimation, and combines the channel and the radio frequency to select the uplink antenna. This can reduce the energy consumption in the communication process while ensuring the quality of user communication.

Please refer to Figure 2. Figure 2 is a schematic structural diagram of an uplink antenna selection device provided by an embodiment of the present application. The uplink antenna selection device includes an uplink channel information acquisition unit, a radio frequency information acquisition unit, a radio frequency information processing unit, and an antenna selection unit. When the terminal communicates with the base station, on the one hand, the uplink channel information acquisition unit obtains the uplink channel information; on the other hand, the radio frequency information acquisition unit obtains the total power consumption data and output power of the current power amplifier module through direct measurement or indirect estimation. The data is saved, and the radio frequency information processing unit uses these data to fit the radio frequency characteristics; among them, the radio frequency characteristics can also be called power amplifier characteristics, that is, the characteristic relationship between the total radio frequency power consumption and the radio frequency output power. Then the uplink channel information and radio frequency characteristics are input into the antenna selection unit, and the antenna selection unit selects the antenna with lower total radio frequency power consumption as the uplink antenna when the requirements of the uplink service are met.

Please refer to FIG. 3 together. FIG. 3 is a schematic flowchart of an uplink antenna selection method provided by an embodiment of the present application. The method includes but is not limited to the following steps:

Step 301: Obtain the current channel status through the uplink channel information obtaining unit.

Step 302: Acquire radio frequency information through the radio frequency information collection unit.

Step 303: Acquire the power amplifier characteristics of each antenna according to the collected radio frequency information.

Step 304: According to the characteristics of the power amplifier and the channel conditions, an antenna with a lower energy consumption is selected.

Specifically, in an actual communication system, on the one hand, due to the different positions of the antennas in the terminal, there are channel differences; on the other hand, the power amplifiers (radio frequency power amplifiers) of the antennas are in different environments due to different manufacturing processes. There are differences in the relationship between the total RF power consumption and the RF output power characteristics. Therefore, selecting a suitable antenna for uplink data transmission will help to reduce the energy consumption of the terminal through power control, etc., while ensuring communication performance.

Among them, there is a non-linear relationship between the total RF power consumption and the RF output power. It is assumed that the non-characteristic relationship between the total RF power consumption of the antenna used by the terminal and the RF output power is shown in Figure 4. In Figure 4, the non-characteristic relationship curve between the total RF power consumption and the RF output power can be expressed as f(p _in )=p _out , the vertical axis PA _in represents the total RF power consumption, and the horizontal and vertical PA _out represents the RF output power. (Alternatively called transmit power). In actual scenes, due to the production process, different temperature and humidity and other objective factors, the power consumption-output power relationship curve of each power amplifier is different to a certain extent, which means that the calculation of total power consumption not only depends on the output power. It also depends on different nonlinear characteristics, so it is necessary to fit the nonlinear characteristics to obtain the total power consumption, and an antenna with a lower total power consumption is selected as the uplink antenna. In this application, the radio frequency information collection unit is responsible for collecting relevant radio frequency information, and the radio frequency information processing unit uses the least square method to fit the relationship between the total radio frequency power consumption and the radio frequency output power characteristics according to the collected radio frequency information.

The technical solutions provided in this application will be described in detail below in conjunction with specific implementations.

Please refer to FIG. 5. FIG. 5 is an antenna selection method provided by an embodiment of the present application. The method includes but is not limited to the following steps:

Step 501: Obtain user information of the terminal, where the user information is used to indicate the transmission quality requirements of the uplink service data of the terminal.

Specifically, since the positions of the antennas in the terminal are different and there are channel differences, the terminal can obtain user information used to indicate the transmission quality requirements of the terminal's uplink service data, so as to learn the current uplink service data transmission based on the user information Quality requirements. For example, the user information includes the service characteristics of the UE, air interface channel quality, and so on.

Step 502: Determine the characteristic relationship between the total radio frequency power consumption and the radio frequency output power corresponding to each antenna of the terminal.

Specifically, the characteristic relationship between the total radio frequency power consumption and the radio frequency output power corresponding to each antenna can be obtained by fitting the radio frequency total power consumption data and the transmission power data of the radio frequency module corresponding to each antenna. The characteristic relationship between power consumption and RF output power is a non-linear characteristic relationship, and different antennas correspond to different characteristic relationships between total RF power consumption and RF output power.

Among them, the terminal can collect the total RF power consumption data of the RF module through direct measurement, for example, use a power meter to directly measure the total power consumption data of the RF module; or the terminal can indirectly infer the total RF power consumption data of the RF module, for example, by The total power consumption data of the terminal indirectly obtains the total power consumption data of the radio frequency module.

Step 503: Select an uplink antenna according to the user information and the characteristic relationship between the total radio frequency power consumption and the radio frequency output power corresponding to each antenna.

Specifically, the terminal can determine the transmission quality requirements of the uplink service data according to the user information, and then can determine the radio frequency output power or the transmission power required for the transmission of the uplink service data, and then use the required radio frequency output power in the corresponding antennas. The characteristic relationship curve between total radio frequency power consumption and radio frequency output power is mapped to obtain a total radio frequency power consumption. The terminal can select the required radio frequency output power mapping to obtain the smallest total radio frequency power consumption corresponding to the antenna as the uplink antenna. The total power consumption of the radio frequency corresponds to the antenna to transmit the uplink service data.

For example, the terminal determines the current rated air interface transmission power, that is, the target radio frequency output power, according to user information used to indicate the transmission quality requirements of the uplink service data of the terminal, which may specifically be the output power of the radio frequency power amplifier

Then, an uplink antenna is selected for the characteristic relationship between the current rated air interface transmit power and the total radio frequency power consumption corresponding to each antenna and the radio frequency output power.

It can be seen that in this embodiment, the terminal can determine the target RF output power for uplink data transmission based on user information indicating the transmission quality requirements of its uplink service data, and then determine the target RF output power for uplink data transmission based on the target RF output power and total RF power consumption. The relationship between the characteristics of the radio frequency output power and the selection of a suitable uplink antenna, so as to make use of the existing terminal transmission mechanism and perform a simple upgrade and transformation, can make the terminal meet the wireless communication quality and reduce the energy consumption in the communication process.

For example, suppose there are 3 antennas in the terminal, namely antenna 1, antenna 2 and antenna 3. Antenna 1 corresponds to the characteristic relationship between total radio frequency power consumption and radio frequency output power 1, and antenna 2 corresponds to total radio frequency power consumption and radio frequency output power The characteristic relationship 2, the characteristic relationship between the total RF power consumption and the RF output power corresponding to the antenna 3, according to the target RF output power

The total power consumption of the target radio frequency mapped on the characteristic relation 1, the characteristic relation 2, and the characteristic relation 3 are respectively

in

Then the terminal selects antenna 1 as the uplink antenna for the current uplink service data transmission.

For example, the uplink channel information can be obtained by estimating the uplink channel to determine the quality of the uplink channel; obtaining the service quality requirement of the current uplink service is also obtaining the QoS requirement of the current uplink service to ensure the transmission quality of the current uplink service .

For example, the terminal determines the current rated air interface transmit power, that is, the output power of the radio frequency power amplifier, according to the uplink channel estimation and the QoS requirements of the current uplink service.

It can be seen that in this embodiment, the terminal comprehensively determines the target radio frequency output power for uplink data transmission according to the uplink channel information and the service quality requirements of the current uplink service, thereby ensuring wireless communication quality.

This application only needs to make corresponding adjustments on the terminal side. In order to obtain the estimation of the uplink channel, the terminal can predict the estimation of the uplink channel through the estimation of the downlink channel, thereby determining the transmission quality status of the uplink channel.

Among them, the uplink channel quality parameter can be used to characterize the transmission quality of the uplink channel, so as to determine how much transmission power the terminal needs under the transmission quality to meet normal communication requirements.

Wherein, the data smoothing processing may be a simple moving average, a window function (hanning window) and other data smoothing processing methods.

For example, suppose there are 3 antennas in the terminal, namely antenna 1, antenna 2, and antenna 3. Collect the total RF power consumption data of antenna 1 and the RF output power data to form data set 1, and collect the total RF power consumption of antenna 2. Data and RF output power data form data set 2. Collect the total RF power consumption data of antenna 3 and RF output power data to form data set 3. According to data set 1, get the characteristic relationship between the total RF power consumption and RF output power corresponding to antenna 1 According to the data set 2, the characteristic relationship 2 of the total radio frequency power consumption and the radio frequency output power corresponding to the antenna 2 is obtained, and the characteristic relationship 3 of the total radio frequency power consumption and the radio frequency output power corresponding to the antenna 3 is obtained according to the data set 3.

For example, for any time t, obtain the total power consumption of the nth RF power amplifier

Simultaneously record the transmit power of the nth RF power amplifier

Then save the corresponding relationship in the past T time period, that is

Among them, τ-T<t<τ (τ is the current time slot), thereby obtaining m total radio frequency power consumption data and m radio frequency output power data of the nth radio frequency power amplifier.

It can be seen that, in this embodiment, the total radio frequency power consumption data and radio frequency output power data corresponding to each of the n antennas at multiple times are acquired within the preset time period, and the m total radio frequency data corresponding to each antenna are obtained. Power consumption data and m radio frequency output power data, and then according to the points composed of these data, the characteristic relationship diagram of the total radio frequency power consumption and the radio frequency output power corresponding to each antenna can be obtained.

For example, since the power amplifiers in the terminal often use the same type, assuming that the power amplifier of this type follows the functional relationship f(p _in )=p _out as shown in Figure 4, it is possible to set τ-T<t<τ( τ is the current time slot) The total radio frequency power consumption data and the radio frequency output power data in the time period are fitted by the least square method to obtain the characteristic relationship between the total radio frequency power consumption and the radio frequency output power corresponding to each antenna.

In some possible implementation manners, according to the m total radio frequency power consumption data and m radio frequency output power data corresponding to each radio frequency power amplifier, the least squares method is used to perform characteristic fitting to determine the each radio frequency power The characteristic relationship between the radio frequency total power consumption and the radio frequency output power corresponding to the amplifier includes: determining the deviation power corresponding to each radio frequency power amplifier; according to the deviation power corresponding to each radio frequency power amplifier, m total radio frequency power consumption data The least squares method is used to perform characteristic fitting with m radio frequency output power data, and the characteristic relationship between the total radio frequency power consumption and the radio frequency output power corresponding to each radio frequency power amplifier is determined.

Among them, the main method of fitting using the least squares method is to assume that the entire radio frequency module has a certain deviation power in the total power consumption, so it is necessary to find a suitable deviation value, so that the characteristic relationship obtained by the fitting is as close as possible. For the data to be fitted.

Specifically, for any antenna n, it can be assumed

It is the deviation value of the power consumption of the entire radio frequency module.

In the formula, n represents the nth RF power amplifier, t represents the time,

Represents the deviation power corresponding to the nth RF power amplifier,

That is, for any antenna n, by solving the above formula, a suitable

And, you can define a function

As the characteristic relationship between the radio frequency total power consumption and the radio frequency output power of the nth radio frequency module, that is, the characteristic relationship between the radio frequency total power consumption and the radio frequency output power corresponding to the antenna n.

Therefore, when determining the characteristic relationship between the total RF power consumption of each antenna and the RF output power

After that, it can be based on the input and output relationship of the RF module of each antenna

Get the total power consumption value of the radio frequency module of the antenna

And choose the antenna with the lower total power consumption value as the uplink antenna.

It can be seen that, in this embodiment, the deviation power used for correction when determining the characteristic relationship between the total radio frequency power consumption and the radio frequency output power is obtained by obtaining the total radio frequency corresponding to each radio frequency power amplifier at multiple times. The power consumption data and the radio frequency output power data are determined, thereby improving the correction effect of the deviation power.
