Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.
The terminal device may be implemented in various forms. For example, the terminal devices may include mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Personal Digital Assistants (PDAs), Portable Media Players (PMPs), navigation devices, wearable devices, and the like, and stationary terminals such as Digital televisions, desktop computers, and the like; the embodiments of the present application are not particularly limited.
Referring to fig. 1, a schematic diagram of a constituent structure of a wireless communication system according to an embodiment of the present application is shown. As shown in fig. 1, the wireless communication system 10 includes a terminal device 110 and a base station 120; terminal device 110 includes antenna 1101. When the terminal device 110 establishes a wireless communication connection with the base station 120, the terminal device 110 may perform data transmission and reception with the base station 120 through a beam formed by the antenna 1101, and the beam needs to be aligned with an antenna beam of the base station 120, so as to facilitate the terminal device 110 to transmit uplink data to the base station 120 or receive downlink data transmitted by the base station 120. Assuming wireless communication system 10 is a millimeter-wave communication system, antenna 1101 may be a millimeter-wave antenna and base station 120 may be a millimeter-wave base station.
Thus, when the terminal device 110 is connected to the millimeter wave communication system, such as FR2 protocol corresponding to the New Wireless interface (5th-Generation New Radio, 5G NR) according to the fifth Generation communication technology or Wireless Fidelity (WIFI) 802.11ad protocol, the beam formed by the terminal device 110 through the antenna 1101 is aligned with the antenna beam of the base station 120. However, since the terminal device 110 may not be in a static state, when the user holds the terminal device, there will always be some operation or action that causes the terminal device 110 to rotate, so that the beam direction of the antenna 1101 may change randomly and rapidly with respect to the base station 120, i.e. the antenna beam of the terminal device 110 may deviate from the antenna beam of the base station 120, resulting in a degradation of communication quality. Although the problem that the antenna beam of the terminal device 110 may deviate from the antenna beam of the base station 120 can also be solved by beam tracking in the conventional beam tracking scheme, the conventional beam tracking scheme performs beam tracking only from the perspective of communication and signals, and the efficiency is very low.
The embodiment of the application provides a beam tracking method, which is applied to terminal equipment. Based on the beam tracking method, when the terminal equipment rotates, the terminal equipment can utilize the characteristics of high precision and short response time of the angular velocity sensor to provide deviation information of the beam direction in time, so that the terminal equipment can track the initial beam direction more quickly, better communication signals are ensured as much as possible, the communication quality is improved, and the efficiency is improved.

s201: acquiring an initial scanning angle of an antenna and initial coordinate information of an antenna plane corresponding to a beam based on the current beam of the terminal equipment; obtaining an initial beam direction corresponding to the beam according to the initial scanning angle of the antenna and the initial coordinate information of the antenna plane;
it should be noted that, when the terminal device is connected to the millimeter wave communication system, the terminal device may perform data transmission and reception with the base station through a beam formed by the antenna, and the beam needs to be aligned with the antenna beam of the base station, so as to facilitate the terminal device to transmit uplink data to the base station or receive downlink data transmitted by the base station. Therefore, according to the current wave beam of the terminal equipment, the initial scanning angle of the antenna and the initial coordinate information of the antenna plane corresponding to the wave beam can be obtained; and according to the initial scanning angle of the antenna and the initial coordinate information of the antenna plane, the initial beam direction corresponding to the beam can be calculated.

The antenna 1101 may be a millimeter wave antenna, and is mainly used for transmitting or receiving electromagnetic signals (such as millimeter wave signals). For the millimeter wave antenna, the millimeter wave antenna may include a plurality of radiating elements, the plurality of radiating elements may synthesize a beam with a certain directional angle, and then the millimeter wave transceiver module may control the angle of the beam by controlling the amplitude and phase of each radiating element.

The wireless Transceiver module 1102 may include a wireless Transceiver (Transceiver), a filter, a Power Amplifier (PA), a Low Noise Amplifier (LNA), and a switch.
The angular velocity sensor 1103 may also be referred to as an angular motion sensor, or a gyroscope, and is mainly used for measuring an angular velocity of the terminal device 110 when rotating. After the angular velocity is obtained, the angular velocity is integrated by the processing module 1106, so that the rotation angle of the terminal device 110 in a time period can be obtained.
The orientation sensing module 1104 may include components such as a gravity sensor and a direction sensor; the gravity sensor is also called an acceleration sensor, and the direction sensor is also called an attitude sensor or an electronic compass. The orientation sensing module 1104 is mainly used for acquiring posture information of the terminal device 110, such as a placement state (a vertical placement state, a horizontal placement state, or the like) of the terminal device 110, and a front facing position (a right east direction, a right west direction, or the like) of the terminal device 110.
The storage module 1105 is mainly used for storing software programs and various data, the processing module 1106 is a control center of the terminal device, and is used for connecting various parts of the whole terminal device by using various interfaces and lines, executing or executing the software programs stored in the storage module 1105 and calling the data stored in the storage module 1105 to execute various functions of the terminal device and process the data, thereby performing overall monitoring on the terminal device 110.
According to the structure of the terminal device shown in fig. 3, the initial antenna scanning angle can be obtained by the radio transceiver module 1102, and the attitude information of the terminal device 110 can be obtained by the orientation sensing module 1104, so as to obtain the initial coordinate information of the antenna plane.

s201 b: acquiring attitude information of the terminal equipment through an azimuth sensing module in the terminal equipment;
s201 c: and obtaining initial coordinate information of the antenna plane according to the attitude information of the terminal equipment and the position information of the antenna in the terminal equipment.
It should be noted that, regarding the beam, the coordinate information of the antenna scan angle or the antenna plane is a parameter located in the three-dimensional space. In three-dimensional space, a spherical coordinate system is used for determining the positions of a midpoint, a line, a plane and a body in the three-dimensional space, and takes a coordinate origin as a reference point, wherein the coordinate origin is represented by a distance (represented by r), an elevation angle (represented by theta) and an azimuth angle (represented by theta)

In the embodiment of the application, the method is applied to the terminal equipment; acquiring an initial scanning angle of an antenna and initial coordinate information of an antenna plane corresponding to a beam based on the current beam of the terminal equipment; obtaining an initial beam direction corresponding to the beam according to the initial scanning angle of the antenna and the initial coordinate information of the antenna plane; determining an antenna target scanning angle according to the initial beam direction and the rotation angle corresponding to the terminal equipment; performing beam tracking on the beam through the antenna target scanning angle, and controlling the antenna scanning angle corresponding to the beam to be adjusted from the antenna initial scanning angle to the antenna target scanning angle; like this, when terminal equipment takes place the rotation action, can acquire terminal equipment's rotation information through angular velocity sensor sensitivity and fast, combine the three-dimensional rotation information that position perception module and antenna's self information can obtain the beam direction fast simultaneously, can in time provide the deviation information of beam direction for terminal equipment can track initial beam direction more fast, thereby guarantee better communication signal as far as possible, has promoted communication quality, has still improved efficiency simultaneously.
In another embodiment of the present application, refer to fig. 4, which shows a flowchart of another beam tracking method provided in the embodiment of the present application. As shown in fig. 4, for S201, before acquiring initial scanning angles of antennas and initial coordinate information of antenna planes corresponding to the beams, the method may further include:
s301: judging whether the current beam quality of the terminal equipment is greater than the preset beam quality;
it should be noted that, by determining the current beam quality of the terminal device, if the current beam quality is greater than the preset beam quality, it is indicated that the beam direction corresponding to the beam is the better beam direction, and at this time, the process of the beam tracking method in the embodiment of the present application may be executed.
It should be noted that the preset beam quality is a preset criterion for determining whether the beam direction is the preferred beam direction. The beam Quality can be determined based on parameters such as Signal Noise Ratio (SNR), Reference Signal Received Power (RSRP), and Reference Signal Received Quality (RSRQ) of the beam. Therefore, in some embodiments, as shown in fig. 4, for determining whether the current beam quality of the terminal device is greater than the preset beam quality, before S301, the method may further include:
s401: determining the current beam quality of the terminal equipment; wherein the beam quality is determined based on at least one of a signal-to-noise ratio, a reference signal received power, and a reference signal received quality of the beam;
that is to say, before determining the current beam quality of the terminal device and the preset beam quality, the current beam quality of the terminal device needs to be determined, and the current beam quality of the terminal device may be determined according to the signal-to-noise ratio of the beam, may also be determined according to the reference signal received power, may also be determined according to the reference signal received quality, may even be determined according to other parameters for measuring the beam quality, and may even be determined by any combination of a plurality of parameters such as the signal-to-noise ratio of the beam, the reference signal received power, the reference signal received quality, and other beam qualities; the embodiments of the present application are not particularly limited.
S302: when the current beam quality of the terminal equipment is greater than the preset beam quality, executing the step of acquiring the initial scanning angle of the antenna and the initial coordinate information of the antenna plane corresponding to the beam;
s303: and when the current beam quality of the terminal equipment is not greater than the preset beam quality, ending the process.
It should be noted that, by determining the current beam quality and the preset beam quality of the terminal device, when the current beam quality of the terminal device is greater than the preset beam quality, step S302 is executed, that is, the flow of the beam tracking method shown in fig. 2 is continuously executed; when the current beam quality of the terminal device is not greater than the preset beam quality, step S303 is executed, and the procedure is ended.
It should be further noted that, by determining the beam quality, it can be reflected whether the beam direction corresponding to the beam is a better beam direction; when the beam direction is poor, the communication quality brought by the beam direction is also poor, and if the beam direction is still subjected to beam tracking, the beam tracking is ineffective and cannot improve the communication quality.
In the embodiment of the application, whether the current beam quality of the terminal equipment is greater than the preset beam quality is judged; when the current beam quality of the terminal device is greater than the preset beam quality, the current beam direction is indicated to be a better beam direction, and the flow of the beam tracking method of the embodiment of the application can be executed at this time, so that invalid beam tracking for the poorer beam direction can be avoided; when the current beam quality of the terminal equipment is not greater than the preset beam quality, the current beam direction is the poor beam direction, and the process is ended, so that invalid beam tracking on the poor beam direction can be avoided; therefore, when the terminal equipment rotates, the rotation information of the terminal equipment can be sensitively and quickly acquired through the angular velocity sensor, the three-dimensional rotation information in the beam direction can be quickly acquired by combining the self information of the azimuth sensing module and the antenna, the deviation information in the beam direction can be timely provided, the terminal equipment can track the initial beam direction more quickly, the beam tracking is only carried out in the better beam direction, the invalid beam tracking in the poorer beam direction is avoided, the power consumption of the terminal equipment can be reduced, and the processing speed of the terminal equipment is improved.
In another embodiment of the present application, refer to fig. 5, which shows a flowchart of another beam tracking method provided in the embodiment of the present application. As shown in fig. 5, for S202, before determining an antenna target scanning angle according to the initial beam direction and the corresponding rotation angle of the terminal device, the method may further include:
s501: when the terminal equipment is in a rotating state, acquiring a rotating angle corresponding to the terminal equipment through an angular velocity sensor in the terminal equipment;
when the terminal device is rotated, the angular velocity sensor 1103 in the terminal device measures the angular velocity of the terminal device during rotation, and the angular velocity is integrated, so that the rotation angle (Δ θ,
Figure BDA0002071858760000101
)。
further, when the rotation angle (Δ θ,
Figure BDA0002071858760000102
) Then, the terminal device may further determine whether the beam needs to be tracked according to the rotation angle. Thus, in some embodiments, as shown in fig. 5, after S501, the method may further include:
s502: judging whether the wave beam needs to be tracked or not;
s503: when the beam is required to be tracked, executing the step of determining the scanning angle of the antenna target;
s504: and ending the process when the beam does not need to be tracked.
It should be noted that, by determining whether the beam needs to be tracked, when the beam needs to be tracked, step S503 is executed, that is, the flow of the beam tracking method shown in fig. 2 is continuously executed; when the beam does not need to be tracked, step S504 is executed to end the process.
It should be noted that, when the terminal device performs a rotation action, if the rotation amplitude is large, or the signal reception quality is greatly affected (for example, a received signal parameter is severely deteriorated), the beam needs to be tracked at this time; if the rotation amplitude is small or the signal reception quality is not greatly affected (for example, the received signal parameters are not deteriorated), the beam tracking may not be performed on the beam at this time, and the procedure is ended.
Specifically, whether the beam needs to be tracked or not is judged, and different judgment rules can be adopted; for example, the determination may be performed according to whether the rotation angle corresponding to the terminal device is greater than a preset angle threshold, or may also be performed according to the degree of deterioration of the received signal parameter caused before and after the rotation of the terminal device, or even may be performed according to other manners, which is not specifically limited in the embodiment of the present application.
In some embodiments, optionally, for S502, the determining whether the beam needs to perform beam tracking may include:
judging whether the rotation angle corresponding to the terminal equipment is larger than a preset angle threshold value or not;
and when the rotation angle corresponding to the terminal equipment is larger than a preset angle threshold value, determining that the beam needs to be tracked.
It should be noted that the preset angle threshold is a preset criterion for determining whether the beam needs to be tracked. In this way, when the rotation angle (Δ θ,
Figure BDA0002071858760000111
) After that, the rotation angle (Δ θ,
Figure BDA0002071858760000112
) Compared to a preset angle threshold, when the rotation angle (Δ θ,
Figure BDA0002071858760000121
) When the rotation amplitude of the terminal equipment is larger than the preset angle threshold, the rotation amplitude of the terminal equipment is larger, and the communication quality is affected badly, so that the fact that the terminal equipment needs to perform beam tracking on the beam can be determined, and the flow of the beam tracking method in the embodiment of the application is continuously executed; when the rotation angle (at) is large (Δ θ,
Figure BDA0002071858760000122
) When the rotation angle is not greater than the preset angle threshold, it indicates that the terminal device does not rotate or the rotation amplitude is small, and at this time, poor influence on the communication quality is not generated, and it can be determined that the terminal device does not need to perform beam tracking on the beam, and the process is ended.
In some embodiments, optionally, for S502, the determining whether the beam needs to perform beam tracking includes:
acquiring a first parameter value corresponding to a received signal parameter before the terminal equipment rotates and a second parameter value corresponding to a received signal parameter after the terminal equipment rotates;
obtaining a first degree value of a received signal parameter according to the first parameter value and the second parameter value;
judging whether the first degree value is larger than a preset degree threshold value or not;
and when the first degree value is larger than a preset degree threshold value, determining that the beam needs to be tracked.
The preset degree threshold is a criterion preset for the received signal parameter to determine whether the beam tracking is required for the beam. When the terminal equipment rotates, a first parameter value corresponding to a received signal parameter before the terminal equipment rotates and a second parameter value corresponding to a received signal parameter after the terminal equipment rotates can be respectively obtained; a first degree value of the received signal parameter may then be determined based on the first parameter value and the second parameter value, the first degree value reflecting a degree of deterioration of the received signal parameter.
Thus, the first degree value is compared with the preset degree threshold, when the first degree value is greater than the preset degree threshold, it is indicated that the rotation amplitude of the terminal device is large, and at this time, poor influence is generated on communication quality, so that received signal parameters are deteriorated, and at this time, it can be determined that the terminal device needs to perform beam tracking on the beam, and the flow of the beam tracking method in the embodiment of the application is continuously executed; when the first degree value is not greater than the preset degree threshold value, it indicates that the rotation amplitude of the terminal device is small, and at this time, poor influence on communication quality is not generated, and the received signal parameter is not deteriorated, and at this time, it can be determined that the terminal device does not need to perform beam tracking on the beam, and the process is ended.
In the embodiment of the present application, the corresponding preset degree thresholds are different for different received signal parameters. The Received Signal parameter may be a Received Signal Strength Indication (RSSI), a reference Signal Received power, or even a parameter corresponding to other Received signals, which is not specifically limited in the embodiments of the present application.
In some embodiments, optionally, for S502, the determining whether the beam needs to perform beam tracking includes:
determining a target beam direction corresponding to the terminal equipment after the terminal equipment rotates based on the rotation angle corresponding to the terminal equipment and the initial beam direction;
calculating the received signal parameters according to the target beam direction and the antenna beam directional diagram to obtain a second range value of the received signal parameters;
judging whether the second degree value is larger than a preset degree threshold value or not;
and when the second degree value is larger than a preset degree threshold value, determining that the beam needs to be tracked.
The preset degree threshold is a criterion preset for the received signal parameter to determine whether the beam tracking is required for the beam. When the terminal device is rotated, the terminal device can be rotated according to the corresponding rotation angle (delta theta,
Figure BDA0002071858760000131
) And initial beam direction (theta)0，
Figure BDA0002071858760000132
) Determining the target beam direction (theta) corresponding to the terminal equipment after rotation1，
Figure BDA0002071858760000133
) Then according to the target beam direction (theta)1，
Figure BDA0002071858760000134
) And calculating the received signal parameters by the antenna beam directional diagram so as to obtain a second degree value of the received signal parameters, wherein the second degree value can also reflect the deterioration degree of the received signal parameters.
Thus, the second degree value is compared with the preset degree threshold, when the second degree value is greater than the preset degree threshold, it is indicated that the rotation amplitude of the terminal device is large, and at this time, poor influence is generated on communication quality, so that received signal parameters are deteriorated, and at this time, it can be determined that the terminal device needs to perform beam tracking on the beam, and the flow of the beam tracking method in the embodiment of the application is continuously executed; when the second degree value is not greater than the preset degree threshold, it indicates that the rotation amplitude of the terminal device is small, and at this time, poor influence on communication quality is not generated, and the received signal parameter is not deteriorated, and at this time, it can be determined that the terminal device does not need to perform beam tracking on the beam, and the process is ended.
In the embodiment of the application, when the terminal equipment is in a rotating state, a rotating angle corresponding to the terminal equipment is obtained through an angular velocity sensor in the terminal equipment; judging whether the beam needs to be tracked or not according to the rotation angle and different judgment rules; when the beam needs to be tracked, it indicates that the terminal device has a rotation action, the rotation amplitude is large, or the signal reception quality is greatly affected (for example, the received signal parameter has a serious deterioration condition), and at this time, the terminal device needs to track the beam; when the beam does not need to be tracked, it indicates that the terminal device does not rotate or the rotation amplitude is small, or the signal reception quality is not greatly affected (for example, the received signal parameter does not have a serious deterioration), at this time, the terminal device does not need to track the beam, and the process is ended; therefore, when the terminal equipment rotates, the rotation information of the terminal equipment can be sensitively and quickly acquired through the angular velocity sensor, meanwhile, the three-dimensional rotation information in the beam direction can be quickly acquired by combining the azimuth sensing module and the information of the antenna, and the deviation information in the beam direction can be timely provided, so that the terminal equipment can track the initial beam direction more quickly; in addition, when the terminal device does not rotate or the rotation amplitude is small, beam tracking is not needed, so that the power consumption of the terminal device can be reduced, and the processing speed of the terminal device is increased.
In a further embodiment of the present application, based on the flow of the beam tracking method shown in fig. 2, for S203, after determining the antenna target scanning angle, the method may further include:
s203 a: controlling the scanning of the wave beam to start from the antenna target scanning angle according to the antenna target scanning angle, and determining the optimal antenna scanning angle;
s203 b: and performing beam tracking on the beam based on the optimal scanning angle of the antenna.
It should be noted that the target scanning angle (θ) of the antenna is determinedant1，
Figure BDA0002071858760000141
) Then, because there may be calculation errors in the process of determining the target scanning angle of the antenna, the target scanning angle of the antenna is not the optimal scanning angle of the antenna; at this time, in order to improve accuracy, the beam scanning of the antenna may be controlled to scan an angle (θ) from the antenna targetant1，
Figure BDA0002071858760000142
) And starting, until the antenna optimal scanning angle is found, the antenna optimal scanning angle can enable the communication quality to be better, and meanwhile, the wireless transmission rate of the terminal equipment is improved. Thus, after the optimal scanning angle of the antenna is found, beam tracking can be performed according to the optimal scanning angle of the antenna.
