[0026] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0027] It should be noted that the terms "first", "second", etc. used in the present application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "include" and "have" and any variations thereof used in the present application are intended to cover non-exclusive inclusion. The term "multiple" used in the present application refers to two or more. The term "and / or" used in the present application refers to one of the options or any combination of multiple options.

[0028] In the current communication scenario, uplink communication is generally transmitted by a single antenna, but in the same communication frequency band, the electronic device generally has multiple antennas that can work to cope with changes in the communication environment and maintain communication quality. The antenna control method provided in the embodiments of the present application can be applied in the application environment as shown in Figure 1 . In the application environment, the electronic device 100 includes a processing circuit 110 and multiple antennas 120, the processing circuit 110 is connected with each antenna 120, the multiple antennas 120 support radio frequency signal transmission (for example, transmission of radio frequency signals of the target frequency band) of the same target frequency band, the processing circuit 110 can select to turn on the communication link of part of the antennas 120 to realize the switching control of the antennas 120. The electronic device 100 can be, but is not limited to, a mobile phone, a tablet computer, a wearable device, a personal notebook computer, etc.

[0029] In an exemplary embodiment, as shown in Figure 2 , an antenna control method is provided, which is applied to the processing circuit 110 in the electronic device 100 as shown in Figure 1 , the electronic device 100 further includes multiple antennas 120 connected with the processing circuit 110, the multiple antennas 120 support radio frequency signal transmission of the target frequency band, the direction patterns corresponding to the multiple antennas 120 are different, and the antenna control method includes:

[0030] S110, acquire a channel type parameter in a current environment of the electronic device and a radiation coverage angle of each antenna of the electronic device in a current posture.

[0031] The channel type parameter refers to a parameter capable of reflecting characteristics of a communication environment in which the electronic device is located. The channel type parameter does not include incoming wave signal data of the environment in which the electronic device is located, but is associated with the incoming wave signal data.

[0032] S120, acquire incoming wave signal data corresponding to a target channel type according to the channel type parameter in the current environment and a channel type library; the target channel type is a channel type matched with the channel type parameter in the channel type library.

[0033] In different environments, there are different wireless channels, and the incoming wave distribution of the channel model is also different. For example, the wireless channels in different environments such as urban canyons, parks, schools, parking lots, office buildings, suburbs, and villages are different. Figure 3 As shown in FIG. 1, in some environments, signals can be transmitted from the direction above the user's head, such as incoming wave 1; in some environments, signals can be reflected from the ground, such as incoming wave 3; and in some environment states, signals can be transmitted horizontally, such as incoming wave 2 (it should be emphasized that this example is only used to simplify the incoming wave direction of the channel model, and in actual scenarios, the incoming wave can come from any direction in space). A channel model in an environment generally includes multiple incoming waves, and the power intensity of different incoming waves is different. The greater the power, the stronger the signal intensity of the incoming wave; conversely, the smaller the power, the weaker the signal intensity of the incoming wave. For wireless channels in different environments, channel acquisition devices can be used to collect and model in different environment states such as urban canyons, parks, schools, parking lots, office buildings, suburbs, and villages, to obtain the channel model in the environment state.

[0034] According to the collected channel model in the network environment, different types of channel models are analyzed, and the angle distribution of the incoming wave of each channel type is obtained, and a corresponding channel type library is established.

[0035] For example, as shown in Table 1, the parameters of the channel model can include the parameters in each column in Table 1. The first column Cluster represents the number of clusters, the second column represents the delay (unit: ns), the third column represents the horizontal angle of arrival AoA, the fourth column represents the pitch angle of arrival ZoA, the fifth column represents the gain of theta polarization, and the sixth column represents the gain of phi polarization.

[0036] Table 1

[0037]

[0038] The gain and angle of arrival of the above-mentioned incoming wave can be expressed as a three-dimensional incoming wave diagram.Figure 4 and Figure 5 The schematic diagrams of the two channel models are given, in which different lines represent the directions of the signal incoming waves, and the length of the line represents the strength of the incoming wave, the longer the length, the greater the gain, and the higher the incoming wave power strength; on the contrary, the shorter the length, the smaller the gain, and the lower the incoming wave power strength. It can be seen that the two channel models have different incoming wave angles and gain distributions, Figure 4 There is a strong incoming wave (such as Figure 4 the side of the red line in the middle), which has a clear direction; and Figure 5 the incoming wave directions in the channel model are relatively dispersed. Therefore, the channel model can be classified based on the parameters in the above table.

[0039] For example, the channel model can be classified into various types as shown in Table 2, such as office building, park, parking lot, suburb, and countryside, which can be classified as type 1, type 2, type 3, and so on. The specific number of types is not limited, the more the sample size of the channel model, the more the number of channel types, and the more accurate the distinction of the environment. Different channel types have different incoming wave angle distribution characteristics, which can be represented by phi distribution and theta distribution, where the phi angle is limited to [0, 360), and the theta angle is limited to [0, 180].

[0040] Table 2

[0041]

[0042] That is, the incoming wave signal data corresponding to different channel types in the embodiment of the application is different. In the application process of the electronic device, it is not necessary to perform incoming wave signal detection, but through channel type matching, the incoming wave distribution under the channel type can be known, which provides data basis for antenna switching. The channel type library can be stored in the cloud or the memory of the electronic device, and the electronic device can access the channel type library through the cloud or the memory of the electronic device when in use.

[0043] S130, according to the matching result of the radiation coverage angle of each antenna of the electronic device under the current posture and the incoming wave signal data, the communication link of the target antenna is turned on, and the target antenna is the antenna with the highest matching degree of the incoming wave signal data in the multiple antennas (i.e. the antenna with the best communication quality).

[0044] Specifically, by acquiring a channel type parameter of the electronic device in a current environment, matching the channel type parameter with channel types in a channel type library, determining a target channel type matched with the channel type parameter, further acquiring a coming wave signal data corresponding to the target channel type, based on a matching result of a radiation coverage angle of each antenna of the electronic device in a current posture and the coming wave signal data, determining a target antenna with good communication quality under the target channel type, and turning on a communication link with the target antenna, the electronic device can quickly switch to the most suitable antenna in the current environment when the environment changes, so as to ensure the communication quality. In this process, without performing coming wave detection, relying on channel classification results of multiple channel models in the channel type library, and based on channel type matching, the coming wave signal data of the current environment of the electronic device can be acquired, and the target antenna with good communication quality can be turned on. On the one hand, compared with the switching mode of matching the coming wave direction under the coming wave detection, the antenna control method provided in the embodiment has high switching speed and high efficiency in different environments. On the other hand, compared with the coming wave detection mode, the target antenna selected is not affected by the accuracy of the coming wave detection (the accuracy of the coming wave detection performed by the electronic device is limited), and the communication quality of the target antenna is good.

[0045] In one embodiment, the target frequency band can include, but is not limited to, LB (Low Band), MHB (Mid High Band), N28 (uplink frequency range 703-748 MHz, downlink frequency range 758-803 MHz), N41 (2496-2690 MHz), and the like.

[0046] In one exemplary embodiment, the channel type parameter includes an environment state in which the electronic device is currently located.

[0047] The environment state reflects the communication environment characteristics of the current environment of the electronic device, and the communication environment characteristics corresponding to different environment states are different. The environment state has a determined corresponding relationship with the channel type. The current longitude, latitude, height, and other data reflecting the location of the electronic device can be obtained by using GPS, WiFi, and the like. Based on these data, the environment in which the electronic device is located is determined to determine the environment state, for example, a park, an office building, a rural area, and the like. Different environment states correspond to different channel types, for example, type 1 corresponds to a park, type 2 corresponds to an office building, and type 3 corresponds to a rural area.

[0048] The channel types in the channel type library can be named according to the characteristics of the wireless channel in addition to being named by type 1, type 2, and the like, for example, multipath fading type (corresponding to an office building environment state), direct dominant type (corresponding to a park environment state), weak signal interference type (corresponding to a rural environment state), fast time-varying type (corresponding to a high-speed rail environment state), and the like. Here, the naming rule of the channel types in the channel type library is not limited, and the naming can distinguish different channel types.

[0049] By obtaining the environment state, the wireless channel condition of the electronic device can be obtained by using the correspondence between the environment state and the channel type, thereby providing data basis for antenna switching control. The process does not need to perform incoming wave detection, has high processing speed, is not affected by the accuracy of incoming wave detection, and has good switching effect.

[0050] In an exemplary embodiment, as shown in Figure 6 the obtaining of the radiation coverage angle of each antenna of the electronic device in the current posture includes:

[0051] S410, obtaining posture angle data of the electronic device.

[0052] S420, obtaining the radiation coverage angle of each antenna of the electronic device in the current posture according to the posture angle data and pre-stored directional diagram data of each antenna.

[0053] The posture angle data of the electronic device can be obtained by using the sensors such as a gyroscope provided in the electronic device. The posture angle data can include a pitch angle and an azimuth angle, which can represent the tilt state of the electronic device. The radiation coverage range of each antenna of the electronic device in different postures changes with the posture. By using the known directional diagram data of each antenna, the radiation coverage angle of each antenna of the electronic device in the current posture in the environment coordinate system can be obtained.

[0054] By obtaining the posture angle data of the electronic device, the radiation coverage angle of each antenna of the electronic device in the current posture is determined by using the correspondence between the posture angle data and the antenna radiation coverage angle. The characteristics of the incoming wave signal of the determined channel type are combined to match the radiation coverage angle of each antenna and the incoming wave signal, so as to select an antenna from multiple antennas to support the signal transmission of the target frequency band based on the principle of ensuring the best communication quality. This method does not need to perform incoming wave detection at the electronic device end, can quickly perform antenna switching when the environment changes, has high switching efficiency, and has high accuracy in selecting the target antenna due to the limitation of the accuracy of incoming wave detection, and has good switching effect.

[0055] In an exemplary embodiment, as shown in Figure 7 the obtaining of the environment state in which the electronic device is currently located includes:

[0056] S510, obtaining geographic position information of the electronic device. The geographic position information can include latitude, longitude, height, etc.

[0057] S520, acquiring an environment state in which the electronic device is currently located according to the geographic location information and the map information. The map information can be acquired from the cloud, and the position of the geographic location on the map can be determined through the geographic location information, and then according to the position of the electronic device on the map, it is determined whether the electronic device is currently in a park or an office building or other environment state.

[0058] The acquisition of the environment state can be realized based on the positioning function of the electronic device itself, without the need for hardware modification. In addition, as described in the above embodiment, the wireless channel is different in different environments, and based on the corresponding relationship, the wireless channel characteristics of the environment in which the electronic device is currently located can be understood through the correspondence from the geographic location information to the environment state and from the environment state to the wireless channel, without the need for incoming wave detection. Compared with the incoming wave detection method, the antenna switching control is fast and accurate.

[0059] In one exemplary embodiment, as shown in Figure 8 According to the channel type parameter in the current environment and the channel type library, the incoming wave signal data corresponding to the target channel type is acquired, including:

[0060] S610, acquiring a target channel type matched from the channel type library according to the environment state in which the electronic device is currently located;

[0061] S620, acquiring the incoming wave signal data corresponding to the target channel type based on the target channel type and the mapping relationship between the channel type and the incoming wave signal data.

[0062] This method for acquiring incoming wave signal data does not need to continuously receive original signals at high power for incoming wave detection, which reduces power consumption and is beneficial to improve the endurance time of the electronic device. In addition, the electronic device does not need to run complex original incoming wave signal analysis algorithms (such as fast Fourier transform, multipath separation, etc.), and the algorithm power occupancy rate is effectively reduced to avoid the electronic device from being stuck due to signal processing.

[0063] In one exemplary embodiment, the incoming wave signal data includes an incoming wave angle and a power intensity parameter. The power intensity parameter refers to a parameter that can represent the power level of the incoming wave, for example, the gain in the direction of the incoming wave.

[0064] By matching the radiation coverage angle of the antenna of the electronic device in the current posture with the incoming wave angle and the power intensity parameter matched with the target channel type, the matching of the incoming wave range and the matching of the power intensity are fully considered, and the antenna with the highest matching degree is selected as the target antenna from two dimensions. If the currently conducting antenna is the target antenna, there is no need to switch, and if the currently conducting antenna is not the target antenna, the target antenna is switched on, and uplink communication is performed through the target antenna. Based on the selected target antenna, the communication quality of the electronic device after switching can be guaranteed to be the best.

[0065] In an exemplary embodiment, the target antenna is the antenna whose radiation coverage angle in the current posture of the electronic device is the largest in the range of the angle of coincidence of the incoming wave angle and the target channel type, and the antenna that can receive the incoming wave with the highest power intensity.

[0066] To illustrate the implementation of the antenna control method provided in the present application, an example is given below. Figure 9 For example, the black arrows represent the distribution of the incoming wave in the matching channel type, and the thickest arrow represents the incoming wave with the highest power intensity. As can be seen from the figure, the incoming wave in the channel type mainly comes from the right side of the electronic device and is scattered on the left side and the top of the electronic device. Therefore, the antenna pattern of the antenna ANT3 located on the right side of the electronic device covers most of the incoming wave (i.e., the range of the angle of coincidence of the radiation coverage angle of the antenna ANT3 in the current posture of the electronic device and the incoming wave angle in the target channel type is the largest), and the antenna ANT3 can also receive the incoming wave with the highest power intensity. Therefore, the antenna ANT3 can be selected as the target antenna (optimal uplink antenna), and if the current uplink antenna is the antenna ANT3, the antenna ANT3 remains unchanged; if the current uplink antenna is another antenna, the antenna ANT3 is switched on.

[0067] In an exemplary embodiment, the step of constructing the channel type library comprises:

[0068] Obtaining parameters of channel models in different environments; the parameters of the channel models include the gain and the angle of arrival of the incoming wave;

[0069] Based on the parameters of the channel models, determining the channel type corresponding to the channel models.

[0070] For different channel models in different environments, the parameters including the gain and the angle of arrival of the incoming wave are collected, the gain and the angle of arrival of the incoming wave can reflect the distribution of the incoming wave, based on the differences in the distribution characteristics of the incoming wave, the channel models are classified, and based on the classification results, a plurality of channel types are obtained. For example, channel models with similar ranges of the angle of arrival of the incoming wave can be classified into one category. Channel models obtained in the same environment state can also be classified into the same category. Through the construction of the channel type library, data basis is provided for the antenna switching control of the electronic device during movement. The antenna switching can be realized without complex incoming wave detection of the electronic device, and the switching efficiency is high.

[0071] In an exemplary embodiment, the parameters of the channel models include a three-dimensional incoming wave graph, the three-dimensional incoming wave graph shows an incoming wave line, the extension direction of the incoming wave line represents the angle of arrival of the signal, and the length of the incoming wave line represents the size of the polarization gain. The three-dimensional incoming wave graph can intuitively show the distribution characteristics of the incoming wave of different channel models, which is beneficial to improve the efficiency of channel type classification.

[0072] In an exemplary embodiment, the polarized gain of different sizes on the three-dimensional wave arrival map corresponds to different colors of the wave arrival lines. Alternatively, only the wave arrival line with the highest power intensity can be displayed in a special color, so as to quickly divide the channel type based on the direction of the wave arrival with the highest power intensity.

[0073] In an exemplary embodiment, the channel type parameter in the current environment of the electronic device is obtained, including:

[0074] In the case of reaching the next cycle period, the step of obtaining the channel type parameter in the current environment of the electronic device, the length of the cycle period is negatively correlated with the size of the moving speed of the electronic device.

[0075] The above method steps can be executed in a cycle, which is suitable for the scene of the movement of the electronic device. The cycle period can be set to any time, such as 10s, 30s, 60s, etc., which depends on the moving speed of the electronic device. The length of the cycle period is negatively correlated with the size of the moving speed of the electronic device. The faster the moving speed of the electronic device, the faster it moves to different environments. At this time, a smaller cycle period is used to execute the above method steps, so that when the electronic device moves to different environments, the communication demand in different environments can be quickly matched by executing the above steps, and the communication quality is ensured. Conversely, the slower the moving speed of the electronic device, the slower it moves to different environments. At this time, a larger cycle period is used to execute the above method steps, which can save energy consumption while matching the communication demand in different environments, and the endurance time of the electronic device and the communication quality of the electronic device are taken into account.

[0076] In an exemplary embodiment, the above method further includes:

[0077] When the moving speed variation threshold of the electronic device exceeds the preset threshold, the cycle period is updated based on the current moving speed.

[0078] The antenna control method provided by the embodiments of the present application quickly switches to the antenna with the best communication quality by using the difference of the wireless channel in different environments and the antenna directional diagram distribution in combination with the user use scene in different environments, improves the uplink transmission throughput, and enhances the user experience.

Unless explicitly stated herein, there is no strict order limitation for the execution of these steps, and these steps can be executed in other orders. Moreover, at least some of the steps in the flowchart involved in each embodiment as described above can include multiple steps or multiple stages, which are not necessarily executed at the same time but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential but can be alternately or alternately executed with at least some of the other steps or steps or stages in other steps.
