The embodiments of the present application will be described in detail below.

The present application provides a user network finding solution based on the carrier direction, which can search for multi-channel signals and obtain the carrier direction information of the multi-channel signals by means of network search or cell measurement when the signal is weak or the signal is out of coverage. Obtaining the direction of the serving cell with smaller signal, the user can improve the wireless communication service by moving the electronic device to the correct direction of the base station. Therefore, the electronic device can re-obtain by moving to the base station with weak signal when there is no service. Wireless communication services to improve communication quality.

A cell refers to an area covered by a base station or a part of the base station (sector antenna) in a cellular mobile communication system, in which electronic devices can reliably communicate with the base station through a wireless channel. Each cell is assigned a different set of channels to achieve frequency reuse. Channel path refers to the set of links from the source to the sink; channel refers to the resources divided by time and frequency that can be allocated to different terminals; carrier refers to all signals modulated to a specific frequency Then through the antenna, this frequency is the so-called carrier. The conditions for staying in a cell are required to meet the cell selection S criterion, that is, S criterion>0, where S is Srxlev, Srxlev=Qrxlevmeas-Qrxlevmin-Pcompensation, Qrxlevmeas is the measured received power of the current serving cell, and Qrxlevmin is the minimum received power of the serving cell, Pcompensation is a compensation value. When S criterion>0, the electronic device can camp in the cell and obtain the communication signal.

Cell search is a prerequisite for an electronic device and a base station to establish a wireless communication link, including the following two situations: device startup and cell handover. When the electronic device is powered on or switched between cells, it needs to obtain new contact with the cell, keep the time-frequency synchronization with the cell, and obtain necessary information of the cell. The cell measurement includes the measurement on the base station side of the electronic device. The measurement of the electronic device includes the measurement of the connected state and the measurement of the idle state. The physical quantities that can be measured include the reference signal reception level RSRP, the reference signal strength indication RSSI and the reference signal. The reception quality RSRQ is generally used for cell selection or reselection in an idle state, and RSRP and RSRQ are usually compared when handover is performed in a connected state.

In this scenario, the signal processing method provided by the present application is beneficial to help users to enhance the signal of the electronic device or to enable the electronic device to obtain the signal again. The present application also provides a network search application based on the carrier direction, when it is detected that the signal strength of the signal currently received by the electronic device is lower than a preset threshold, including the situation that the number of signal bars is displayed as zero and the display is no service , at this time, the electronic device can start the network search application, and obtain the multi-channel signal and parameter information of the multi-channel signal that the electronic device can search for at the current location through network search and cell measurement, wherein the multi-channel signal includes the electronic device. For cell signals that can be searched but do not meet the camping conditions, the application interface of the search network application can display the multi-channel signals searched by the electronic device. When the target signal is selected from the multi-channel signals, the carrier direction of the target signal can be determined according to the parameter information of the target signal, so as to prompt the user to move the electronic device to the carrier direction of the target signal through the Internet search application, and on the application interface The carrier direction and the direction of the electronic device can also be displayed in real time to facilitate user calibration. In this way, when the electronic device moves to the correct direction of the base station, the wireless communication service can be improved or reacquired.

Please refer to FIG. 1A . FIG. 1A is a schematic flowchart of a signal processing method provided by an embodiment of the present application, which is applied to an electronic device. As shown in the figure, the signal processing method includes:

S101, when the electronic device detects that the signal strength of the signal currently received by the electronic device is lower than a preset threshold, obtains multi-channel signals and parameter information of the multi-channel signals through network search or cell measurement, and the multi-channel signals The channel signal includes the cell signal for which the electronic device does not meet the camping condition.

The preset threshold value can be preset by the user. By setting the preset threshold value, the signal strength of the currently received signal is lower than the preset threshold value, which may include that the signal display is only 0 grid, 1 grid, etc., resulting in poor communication service quality during terminal use. High (such as low call quality, unstable received information), also includes the terminal signal is displayed as no service. The electronic device can obtain the multi-channel signals that can be searched by the current location of the electronic device through network search or cell measurement, as well as parameter information of the multi-channel signals. The parameter information may include, for example, parameters such as signal strength, received power, and signal stability. , the multi-channel signal includes the cell signal searched by the electronic device that does not meet the camping conditions. As shown in FIG. 1B , although the electronic device 101 can search for the signal sent by the base station NB102 , because the electronic device 101 loses coverage, the screen interface will display a warning message that the signal is out of service, where S criterion<0.

S102, the electronic device selects a target signal from the multi-channel signals, and determines a carrier direction of the target signal.

Among them, the electronic device can display the searched multi-channel signals and the parameter information of the multi-channel signals through the application interface of the search application, and select the target signal from the multi-channel signals. Specifically, the electronic device can select the currently searched signal strength by default. A good signal is the target signal, or the user selects it according to the displayed multi-channel signals. After the target signal is determined, the electronic device can further determine the carrier direction of the target signal.

且每根接收天线都是同幅同相，以单极化天线阵列为例，此时d对应d2，载波方向的具体计算过程如下：Among them, when determining the carrier direction of the target signal, it is assumed that the electronic device adopts multi-antenna reception, and the arrangement of the antennas is shown in Figure 1C, (a) is a reference example of a dual-polarized antenna array, (b) is a single-polarized antenna array. The reference example diagram of the antenna array, the number of antennas in one polarization direction is N _RX , X represents the specific number of antennas, and X in FIG. 1C is 4, which is only a reference example, and the actual number of antenna X is not made here. The specific number of antennas is determined by the hardware parameters of the electronic device itself. If the terminal adopts dual-polarized antennas, the actual number of receiving antennas is 2N _RX , and the antenna spacing is d. For details, please refer to the spacing d1 between dual-polarized antennas or the spacing d2 between single-polarized antennas in FIG. 1C . If the carrier frequency of the received signal is f, then the wavelength of the signal

And each receiving antenna is of the same amplitude and in phase. Taking a single-polarized antenna array as an example, d corresponds to d2 at this time, and the specific calculation process of the carrier direction is as follows:

(1) Calculate the channel estimation value h _{nrx, k} on each sub-carrier of each receiving antenna through the single sideband (Single Side Band, SSB) signal, where k represents the specific number of carriers, and the formula is as follows:

h _nrx,k =r _nrx,k /s _nrx,k

In the formula, r _nrx,k represents the received signal value, and s _nrx,k represents the reference signal value.

(2) Calculate the channel correlation matrix. For the channel of the dual-polarized antenna, the channel correlation matrix of each polarization direction can be calculated separately, and then the channel correlation matrix of the two polarization directions can be superimposed to obtain the total channel correlation matrix. The formula is calculated as follows:

H_k ^H为H_k的共轭转置矩阵。in the formula

H _k ^H is the conjugate transpose matrix of H _k .

其中，如图1D所示，为AOA向量的参考示例图，计算AOA向量表与信道相关矩阵的相关值：(3) Calculate the relative incoming direction of the signal, assuming that the pre-stored AOA vector table is

Among them, as shown in Figure 1D, it is a reference example of the AOA vector, and the correlation value between the AOA vector table and the channel correlation matrix is calculated:

corr _θ = V·R·V ^H

Then calculate the maximum value AOA=max _θ (corr _θ ) of the correlation value, and then obtain the carrier direction according to the angle value of θ corresponding to the maximum value.

S103, the electronic device prompts the user to move in the direction of the carrier wave of the target signal.

Among them, after the carrier direction of the target signal is determined, the carrier direction can be displayed on the application interface of the web search application, and the user is prompted to move the electronic device toward the carrier direction, so that the distance between the electronic device and the base station can be reduced, so that the The target signal received by the electronic device is enhanced and meets the cell camping conditions. As shown in FIG. 1E , it can be seen that the electronic device 101 moves toward the carrier direction of the target signal, so that S<0 becomes S>0, so that a better signal can be obtained. In addition, when the user makes S>0 by moving, the user can be reminded, so that the user can choose whether to close the search network application and stop moving.

It can be seen that, in this embodiment of the present application, when the electronic device first detects that the signal strength of the signal currently received by the electronic device is lower than the preset threshold, it acquires the multi-channel signal and the multi-channel signal through network search or cell measurement. parameter information, the multi-channel signal includes the cell signal that the electronic device does not meet the camping conditions, secondly, the target signal is selected from the multi-channel signal, and the carrier direction of the target signal is determined, and finally, the user is prompted Move in the direction of the carrier of the target signal. Since the electronic equipment can obtain multiple signals by means of network search and cell measurement and select the target signal from the multiple signals in the case of weak signal or loss of coverage, it can move to the base station by moving in the direction of the carrier of the target signal. The quality of wireless communication service is beneficial to help the electronic device to regain the wireless communication service by moving to the carrier direction when there is no service.

In a possible example, the parameter information includes the signal strength of the multi-channel signals; the selecting the target signal from the multi-channel signals includes: selecting the signal with the highest signal strength among the multi-channel signals as the target signal. or outputting a notification message for prompting the user to select a target signal from the multi-channel signals, and after receiving the user's selection operation, determine that the signal corresponding to the selection operation is the target signal.

Among them, the strength of each signal in the searched multi-channel signals is different. If the setting of the search network application is that the electronic device automatically selects the target signal, the electronic device can directly select the signal with the highest signal strength among the multi-channel signals. As the target signal, after the carrier direction of the target signal is determined, the user only needs to move the electronic device a short distance, or the electronic device can improve the communication quality or regain the wireless communication service by moving faster. If the setting of the search network application is to select the target signal of the multi-channel signal displayed by the user on the application interface, the application interface can output a notification message for prompting the user to select the target signal. After viewing the notification message, the user can The target signal of the multi-channel signal searched by the electronic device is selected according to its own situation, so as to move according to the carrier direction of the target signal, so that the communication quality of the electronic device can be improved.

It can be seen that, in this example, the determination of the target signal can be selected by the electronic device or by the user, and the user only needs to set it in the setting function interface of the search network application in advance. The method of determining the target signal is beneficial to improve the diversity of target signal selection.

In a possible example, the parameter information includes a carrier direction of the multi-channel signal; the selecting a target signal from the multi-channel signal includes: detecting whether the scene where the electronic device is currently located is a moving scene; , determine the moving direction corresponding to the moving scene, and select a signal whose carrier direction matches the moving direction from the multi-channel signals as the target signal.

The parameter information of the multi-channel signal may also include the carrier direction of the multi-channel signal. When it is detected that the scene where the electronic device is currently located is a moving scene, the specific detection method may be to detect the moving speed and moving duration of the electronic device. If both the moving speed and the moving duration satisfy the judgment conditions set by the moving scene, it can be determined that the electronic device is in a moving scene.

For example, when a user is taking a car, train, high-speed rail and other means of transportation, the user may not be able to choose his own moving direction at will, but he can predict the user's moving direction, such as according to the user's current location, destination, and the vehicle he is taking. The user's approximate moving route is determined to determine the optimal moving direction of the electronic device. At this time, a signal matching the carrier direction and the moving direction can be selected from the multi-channel signals as the target direction.

It can be seen that in this example, when the electronic device is in a moving scene, the signal with the strongest signal should not be directly selected as the target signal. Therefore, it can help electronic devices to obtain wireless communication services more quickly.

In a possible example, the parameter information includes a carrier direction of the multi-channel signal; the selecting a target signal from the multi-channel signal includes: acquiring the current location information of the electronic device; according to the location information, respectively calculate the probability of the electronic device moving to the carrier direction of the multi-channel signal; determine the target signal according to the probability.

The parameter information of the multi-channel signal may also include the carrier direction of the multi-channel signal, and the application interface of the search application can simultaneously display the carrier direction of each signal. information, respectively calculate the probability of the electronic device moving to the carrier direction corresponding to the multi-channel signal, and then select the signal with the highest probability as the target signal.

For example, when the user himself wants to go to a certain destination, the user's moving route is determined according to the position of the electronic device and the destination location. If the carrier direction of the signal A is the same as the moving route, the user will The carrier direction of signal A has a high probability of moving, and signal A can be selected as the target signal, which is beneficial for the user to avoid detours. For another example, according to the current location of the user, determine the user's route to the multi-channel signal carrier direction and the way forward. It is difficult to travel the same straight line distance. If the user moves to the carrier direction of signal B, there are many obstacles, and the efficiency of moving forward in a straight line distance is low, and the probability of the user moving to the carrier direction of signal B is small. Therefore, it should be selected The signal C that can travel more straight distances by walking less distance is the target signal.

It can be seen that in this example, the probability of the electronic device moving to the carrier direction of the multi-channel signal can be further calculated according to the position information of the electronic device, so that the target signal is selected according to the probability, which is beneficial to ensure that the user moves to the carrier direction of the target signal while moving to the carrier direction of the target signal. Reduce the impact on target users and improve mobile efficiency.

In a possible example, the method further includes: adjusting the physical posture of the electronic device, where the adjustment is used to fix the orientation of the antenna of the electronic device; prompting the user to maintain the current physical posture of the electronic device attitude.

Among them, the physical posture of the electronic device also needs to be adjusted. The adjustment is mainly used to determine the orientation of the antenna and fix the orientation of the antenna, and prompt the user to maintain the current physical posture of the electronic device to move, so as to avoid calculating the target in real time on the electronic device. An error occurs in the direction of the carrier of the signal.

It can be seen that in this example, since the determination of the carrier direction of the target signal is related to the position of the antenna, the azimuth of the antenna needs to be fixed, and the user is reminded to operate the electronic device in the current physical attitude, so as to avoid the change of the azimuth of the antenna, which may cause The calculated carrier direction has a large error.

In a possible example, the method further includes: when detecting that the physical posture of the electronic device changes, determining a relative positional relationship between the physical posture after the change and the physical posture before the change; The position relationship adjusts the calculation method of the carrier direction of the target signal, so that the change of the physical attitude will not cause the calculation result of the carrier direction to change.

Among them, if it is detected that the physical posture of the electronic device changes, such as the horizontal angle of the electronic device changes or the vertical angle changes, at this time, the position of the antenna changes, and the angle between the antenna and the received signal also changes. The electronic device needs to calculate the carrier direction of the target signal in real time according to the current position. Therefore, it is necessary to determine the relative positional relationship between the physical posture after the change and the physical posture before the change, and according to the relative positional relationship, the carrier direction of the target signal needs to be determined. The calculation method is adjusted so that the change of the physical posture of the electronic device will not cause the calculation result of the carrier direction to change. The direction of the carrier never changes and always points to the direction of the base station.

It can be seen that in this example, when a change in the physical posture of the electronic device is detected, the calculation method of the carrier direction of the target signal is adjusted by determining the relative positional relationship between the physical posture before the change and the physical word strip after the change, so that It can be ensured that the calculation result of the carrier direction will not change due to the physical posture of the electronic device, which is beneficial to reduce errors.

In a possible example, after the determination of the carrier direction of the target signal, the method further includes: displaying the current direction of the electronic device and the carrier direction of the target signal in the form of a compass interface, wherein the The current direction of the electronic device is the pointer direction, and the carrier direction of the target signal is the highlighted target direction.

The display interface of the carrier direction of the target signal can be a compass interface, the pointer points to the current orientation of the electronic device, and the orientation of the electronic device can be updated in real time during the user's movement, and the carrier direction is highlighted on the display interface, thereby helping the user. can move to the correct carrier direction.

It can be seen that in this example, the orientation of the electronic device and the carrier direction of the target signal are displayed in the form of a compass interface, which can help the user to accurately identify the carrier direction in the process of moving to the carrier direction. The user carries the electronic device to move toward the base station more efficiently and accurately, so that the electronic device can regain the wireless communication service.

Consistent with the embodiment shown in FIG. 1A , please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a signal processing method provided by an embodiment of the present application, which is applied to an electronic device. As shown in the figure, the signal processing method includes:
