Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic structural diagram of a user terminal device according to an embodiment of the present application; FIG. 3 is a schematic diagram of the user terminal device of FIG. 2 with the housing removed; fig. 4 is a circuit block diagram of a user terminal device according to another embodiment of the present application. The user terminal device 1 comprises a housing 220. The housing 220 may be in the shape of a multi-sided cylindrical barrel, or a cylindrical barrel. The material of the housing 220 may be, but is not limited to, an insulating material such as plastic. It is to be understood that in other embodiments, the user terminal device 1 may not include the housing 220.

The user terminal device 1 further includes a first antenna 110 and a signal conversion device 120. The first antenna 110 is rotatable to receive first network signals from different directions, the signal conversion device 120 converts the first network signal with the strongest signal in the first network signals received by the first antenna 110 from different directions into a second network signal, and the signal conversion device may specifically include a radio frequency processing circuit of the first antenna, a processor, and a radio frequency processing circuit of the second network signal, for example, may convert a received 5G signal into a Wi-Fi signal and transmit the Wi-Fi signal through a Wi-Fi antenna, or convert a received Wi-Fi signal into a 5G signal and transmit the Wi-Fi signal through the first antenna, so that the user terminal device can implement network relay service in a wireless manner.

In addition, the user terminal device 1 further includes a processor 130, a radio frequency processing circuit, and a rotation control device, where the processor 130 is electrically connected to the first antenna 110 through the radio frequency processing circuit, the processor 130 is electrically connected to the rotation control device, the rotation control device is connected to the first antenna 110, and the first antenna 110 is an antenna supporting a 5G network system; wherein the content of the first and second substances,

the first antenna 110 is configured to transmit a wireless signal (i.e., the first network signal);

the rotation control device is configured to control the first antenna 110 to rotate;

the processor 130 is configured to control the first antenna 110 to rotate to multiple directions through the rotation control device, and perform signal measurement in each direction to obtain multiple measurement results; and determining a target direction from the plurality of measurements; and controlling the first antenna 110 to rotate to the target direction by the rotation control device to complete the antenna direction calibration.

When the user terminal apparatus 1 includes the housing 220, the first antenna 110 and the signal conversion device 120 may be disposed in the housing 110.

The first antenna 110 may be, but is not limited to, a millimeter wave antenna or a terahertz antenna. Accordingly, the first network signal may be, but is not limited to, a millimeter wave signal or a terahertz signal. Currently, in the fifth generation mobile communication technology (5th generation wireless systems, 5G), according to the specification of the 3GPP TS 38.101 protocol, a New Radio (NR) of 5G mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. Wherein, the frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, and belongs to the millimeter Wave (mm Wave) frequency band. The 3GPP Release 15 specification specifies that the current 5G millimeter wave frequency band includes: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz). Millimeter wave or terahertz signal have transmission speed advantage such as fast, however, millimeter wave or terahertz signal are sheltered from by external object easily. When there is an object blocking between the first antenna 110 and the base station 3, the signal strength of the first network signal received by the first antenna 110 is weak, and at this time, if the first network signal with weak signal strength is converted into the second network signal, the signal strength of the obtained second network signal may also be weak.

For the user terminal device 1 placed at a certain position, the signal strength of the first network signal in each direction of the first antenna 110 is different. In the present embodiment, the first antenna 110 in the user terminal device 1 is rotatable, and when the first antenna 110 is located in the direction in which the signal strength of the first network signal is strongest, the first antenna 110 stays in the direction in which the signal strength of the first network signal is strongest. The signal conversion device 120 converts the first network signal with the strongest signal received by the first antenna 110 into the second network signal. The signal conversion device 120 in the user terminal device 1 in this embodiment converts the first network signal with the strongest signal into the second network signal, so as to ensure the signal strength of the second network signal, and further ensure the communication quality when communicating by using the second network signal.

In one embodiment, in the aspect of controlling the first antenna to rotate to a plurality of directions by the rotation control device, the processor 130 is specifically configured to: and controlling the first antenna to rotate to a plurality of directions in a non-sequence mode through the rotation control device according to the principle that the directional coherence is low.

Therefore, the direction coherence of continuous rotation measurement is minimum, so that the direction coverage can be quickly finished, and when the optimal cell is judged by self, judgment can be directly initiated after a certain detection direction is searched, so that the network searching speed is improved.

In one embodiment, the rotation direction of the first antenna is divided into four directions, namely a first direction, a third direction adjacent to the first direction, a second direction adjacent to the third direction, and a fourth direction adjacent to the second direction; the multi-directional rotation strategies are as follows: rotating from the first direction to the second direction, then from the second direction to the third direction, and then from the third direction to the fourth direction.

Therefore, the direction coherence of the two rotations is minimum, so that the direction coverage can be quickly finished, and when the optimal cell is judged by self, judgment can be directly initiated after a certain detection direction is searched, so that the network searching speed is improved.

In one embodiment, the rotation direction of the first antenna is divided into five directions, which are a first direction, a third direction adjacent to the first direction, a fifth direction adjacent to the third direction, a second direction adjacent to the fifth direction, and a fourth direction adjacent to the second direction; the multi-directional rotation strategies are as follows: the first direction, the second direction, the third direction, the fourth direction and the fifth direction.

Therefore, the direction coherence of the four rotations is minimum, so that the direction coverage can be quickly finished, and when the optimal cell is judged by self, judgment can be directly initiated after a certain detection direction is searched, so that the network searching speed is improved.

In one embodiment, in the determining the target direction according to the plurality of measurement results, the processor 130 is specifically configured to: determining a target measurement result with optimal signal receiving quality according to the plurality of measurement results; and determining the rotating direction corresponding to the target measurement result as a target direction.

The user terminal equipment can judge the optimal direction by itself and only report the cell searched by the target direction after self judgment, the mechanism is not restricted by a high-pass module and is decoupled with third parties such as a high pass, the module only sees the antenna result, and the antenna measurement is not required to be perceived as rotating antenna measurement.

Therefore, in this example, since the user terminal device automatically determines the optimal direction and only reports the antenna result, the antenna direction calibration method is decoupled from third-party chips such as the high-pass module, the complexity of signaling interaction inside the user terminal device is reduced, and the antenna direction calibration efficiency is improved.

In one embodiment, in the determining the target direction according to the plurality of measurement results, the processor 130 is specifically configured to: reporting the measurement results in the multiple directions to a first base station through the first antenna, wherein the measurement results are decided by the first base station to be in the target direction and are issued to the user terminal equipment; and receiving the target direction from the first base station through the first antenna.

Because the omnidirectional information is collected at this time, the user terminal equipment can selectively report the omnidirectional direction signal to the first base station, so that the base station can select a proper cell, and after receiving the 5G access information sent by the base station, the CPE matches the current measurement direction according to the target cell and rotates to record the measurement direction at that time. The cell selection decision is judged by the base station, so that the base station can comprehensively consider information such as cell load and the like.

In one embodiment, in terms of performing signal measurement in each direction, the processor 130 is specifically configured to: interacting with the first base station in each direction for signal measurements.

In one embodiment, the first antenna includes a plurality of receiving modules;

the measurement result of the current direction is the comprehensive measurement information of the plurality of receiving modules; alternatively, the first and second electrodes may be,

the measurement result of the current direction is a plurality of pieces of measurement information of the plurality of receiving modules, and the plurality of pieces of measurement information and the directivities of the plurality of receiving modules are used as judgment inputs of rotation and measurement reporting.

If the measurement result of the current direction is the comprehensive measurement information of the plurality of receiving modules, the current direction comprehensive information is obtained by the user terminal equipment in each direction through measurement, the selection of the plurality of receiving modules in the first antenna is not identified, the output result of the algorithm in the antenna module (which is equivalent to the acquisition of the signal value of the antenna in the current direction) is directly used, the scheme is realized by inheriting the current high-pass third-party module, the existing antenna algorithm is not required to be modified, the coupling degree is low, the defects are that the direction accuracy is poor, secondary focusing is required, and the convergence speed of the alignment algorithm is influenced.

If the measurement result of the current direction is the measurement information of the receiving modules, acquiring information of each receiving module of the first antenna, directly modeling the receiving module in the first antenna, and combining the directivity and the receiving condition of the module as the judgment input of the subsequent rotation and measurement report. The scheme needs to be customized by combining with the current antenna module, has high coupling degree, and has better gain for the subsequent antenna rotation algorithm.

In one embodiment, the processor 130 is further configured to: receiving a fifth generation mobile communication technology 5G network access command from the first base station through the first antenna; and initiating a 5G network access process according to the 5G network access command.

As can be seen, in this example, the user terminal device performs cell access after completing measurement to determine a target direction, and may perform omni-directional measurement coverage, but since access is not completed, it is not necessarily an optimal choice because it is not possible to obtain a beam convergence signal gain performed by an antenna of the first base station after access.

In one embodiment, in terms of performing signal measurement in each direction with the first base station, the processor 130 is specifically configured to: controlling, by the rotation control means, the first antenna to rotate to each of a plurality of directions, for which the following is performed: and in the measurement period of the current direction, interacting with the first base station to execute the signal measurement of the current direction to obtain the measurement result of the current direction.

The signal measurement may be a 5G signal measurement, where the 5G signal measurement specifically refers to a measurement of a 5G signal parameter implemented by a ue and a first base station through signaling interaction, and the measurement result specifically may include at least one of the following: RANK (RANK) indicating the number of MIMO layers of a transmission channel, Received Signal Strength Indication (RSSI), Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR).

In a specific implementation, when each measurement is performed, the user terminal device does not make a conditional decision on whether a cell is accessed based on a current detection result, but obtains detection results in all directions first, and then further makes direction selection, which is a mechanism different from the existing protocol and is specifically controlled by the home terminal of the user terminal device.

For the first base station, under the constraint of the standard protocol, after the first base station issues the measurement signaling in the period configured for the current measurement of the user terminal equipment, if the feedback information is not received, the first base station will repeat the transmission until the current measurement period is finished or the feedback information is received.

Therefore, if the omni-directional detection process of the ue can be adapted to the retransmission mechanism, it is possible to perform omni-directional detection in the standard measurement period configured by the base station, provided that the omni-directional measurement duration of the ue is shorter than the duration of the standard measurement period configured by the base station.

If the omni-directional detection process of the user terminal equipment cannot adapt to the retransmission mechanism, and/or the omni-directional measurement duration of the user terminal equipment is longer than the duration of the standard measurement period configured by the base station, or the user terminal equipment does not set the omni-directional measurement period, the method can be carried out according to the measurement period configured by the base station, and the user terminal equipment needs to forcibly quit the network to continuously obtain the measurement opportunity, namely, network side network access information is cleared, and a new measurement opportunity is obtained through re-network access.

Therefore, in this example, the user terminal device traverses the measurement results in all directions, and can perform comprehensive analysis based on the omnidirectional information, thereby improving the accuracy of direction calibration.

In one embodiment, the measurement periods of the plurality of directions are determined by a standard measurement period configured by the first base station; the standard measurement period is a general measurement period appointed by a standard protocol.

The user terminal equipment adopts a general measurement period appointed by a standard protocol, and can adapt to the following two conditions.

In case 1, the time length required for the ue to perform the current multi-directional 5G measurement is less than the measurement period configured by the base station. If the multiple directions are 2 directions, the measurement period of the 2 directions is 2 seconds, and the measurement period configured by the base station is 5 seconds, after the user terminal equipment and the first base station interactively determine to start measurement, the first base station only needs to issue a measurement signaling according to the request of the user terminal equipment in the current period.

In case 2, if the required duration of the current multi-directional 5G measurement performed by the user terminal device is longer than the measurement period configured by the base station, or the required duration of the multi-directional 5G measurement cannot be determined (that is, configured as aperiodic measurement), the measurement is performed according to the measurement period configured by the base station, and the measurement opportunity is continuously obtained by forcibly quitting the network.

As can be seen, in the present example, the measurement process of the ue only requires the first base station to perform measurement period configuration according to the standard protocol, and the network side does not need to change the protocol, so that the implementability is strongest.

In one embodiment, the measurement periods of the multiple directions are determined by an extended measurement period configured by the first base station; the extended measurement period is a dedicated measurement period customized for the device type of the user terminal device;

and the equipment type is reported to the first base station through a capability indication.

The first base station can issue periodic 5G measurement, the expected measurement period is less than 1 second (the shorter the actual value is, the better), and the behavior can effectively promote the user terminal equipment to complete rotation measurement as soon as possible.

In addition, the user terminal equipment starts antenna rotation type space measurement through protocol definition extension type periodic measurement, full space signal measurement is completed through rotation, and a measurement result is reported, wherein the measurement result can contain relative coordinates, and the behavior can assist the base station to understand full space signal layout and can also help the base station to provide input when the base station controls the user terminal equipment to switch. The user terminal equipment carries the time required by one-time full-space measurement on the capability for the base station to judge. Or after the first base station identifies the type of the user terminal equipment, configuring a measurement period meeting the signal measurement requirement of the user terminal equipment.

In addition, the protocol defines that the cell switching indication comprises the antenna space direction, the user terminal equipment reports the space relative coordinate, the user terminal equipment rotates firstly and then completes cell switching, and the protocol mechanism can improve the antenna rotation precision and performance and improve the user experience of cell switching.

Therefore, in this example, the measurement process of the user terminal device is constrained by a protocol, so that the first base station can be adapted to the signal measurement requirement of the local terminal synchronously, thereby implementing an exclusive configuration measurement period, ensuring that the signal measurement process can be completed effectively, and improving the success rate and stability of antenna calibration.

In one embodiment, the first antenna is a millimeter wave antenna; the user terminal equipment also comprises a second antenna used for providing basic data service in a preset frequency band lower than the millimeter wave frequency band; the first base station is a base station in an independent networking SA; the processor 130 is further configured to: and initiating a 5G NR network access process at the preset frequency band through interaction between the second antenna and the first base station, and successfully residing.

The second antenna is an antenna supporting a SUB-6G frequency band, that is, the preset frequency band may be the SUB-6G frequency band.

In a specific implementation, the user terminal device may interact with the first base station in the SUB-6G band to perform 5G NR access in the 5G standard, so as to implement network access in the SUB-6G band. The wireless hotspot function of the local terminal is started, specifically, the wireless high-fidelity Wi-Fi hotspot is started, so that the user terminal equipment can access the hotspot to realize networking service in a 5G SUB-6G frequency band.

In addition, after the user terminal equipment realizes the network access of the 5G millimeter wave frequency band through the millimeter wave antenna, the user terminal equipment and the SUB-6G frequency band can realize the carrier aggregation function.

Therefore, in this example, the user terminal device may provide basic data service for the user terminal device based on 5G SUB-6G frequency band communication in the process of controlling the direction calibration of the millimeter wave antenna, which is beneficial to improving the stability and continuity of the user terminal device.

In one embodiment, the first antenna is a millimeter wave antenna; the user terminal equipment also comprises a third antenna for initiating a fourth generation mobile communication technology 4G long term evolution LTE network access process; the first base station is a base station in a non-independent networking NSA; the processor 130 is further configured to: and initiating a 4G LTE network access process with the first base station through the third antenna and residing successfully.

The third antenna is an antenna supporting a 4G frequency band, and the standard protocol of the NSA supports the network access device to simultaneously maintain 4G communication and 5G communication with the network side.

In specific implementation, after the user terminal device and the current NSA complete 4G LTE network access, a wireless hotspot function of the local terminal is started, specifically, a wireless high-fidelity Wi-Fi hotspot is started, so that the user terminal device can access the hotspot to realize networking service of a 4G frequency band.

It can be seen that, in this example, the user terminal device may provide basic data service for the user terminal device based on 4G communication in the process of controlling the direction calibration of the millimeter wave antenna, and although the data transmission speed and the bandwidth are not as high as the 5G index, it may be ensured that the device is currently usable, and cannot be used due to the adjustment of the millimeter wave antenna, which is beneficial to improving the stability and continuity of the use of the user terminal device.

In one embodiment, the first antenna 110 may be rotated manually or automatically, as long as the first antenna 110 can be rotated. In this application, the first antenna 110 may be automatically rotated, and the device for driving the first antenna 110 to automatically rotate will be described later.

Referring to fig. 5 and fig. 6 together, fig. 5 is a schematic structural diagram of a part of a device of a user terminal device according to another embodiment of the present application; FIG. 6 is a schematic diagram of a driver according to an embodiment. Only the components of the user terminal device 1 related to the first antenna 110 and driving said first antenna 110 are illustrated in fig. 5, while other components of said user terminal device 1 are omitted. Specifically, the user terminal device 1 further includes a base 140, a support 150, and a driver 160 (corresponding to the above-mentioned rotation control device). The base 140 is rotatably connected to the bracket 150, the first antenna 110 is disposed on the bracket 150, and the driver 160 is configured to receive a control signal from the processor 130, and drive the bracket 150 to rotate to a direction in which the first network signal is strongest relative to the base 140 under the control of the control signal.

The base 140 is fixed, for example, the base 140 may be directly or indirectly fixed on the housing 220 (see fig. 2) of the user terminal apparatus 1. The bracket 150 is rotatably connected to the base 140, and when the first antenna 110 is disposed on the bracket 150 and the driver 160 drives the bracket 150 to rotate, the bracket 150 drives the first antenna 110 to rotate. The driver 160 may include, but is not limited to including, a motor, etc. The base 140 forms an enclosure and the driver 160 is disposed within the enclosure formed by the base 140.

The first antenna 110 includes a plurality of receiving modules 112 to form an antenna array. In this embodiment, the number of the receiving modules 112 is 2 as an example. The receiving module 112 is disposed on a substrate 113. The substrate 113 may be, but not limited to, a circuit board or the like.

In one embodiment, referring to fig. 6, the driver 160 includes a driving motor 161 and a reducer 162. The driving motor 161 is fixed on the base 140, the driving motor 161 is controlled by the control signal to rotate, the step angle of the driving motor 161 is a first angle, the speed reducer 162 is engaged with the output shaft of the driving motor 161 and the speed reducer 162 is rotationally connected to the support 150, and the speed reducer 162 is used for converting the first angle into a second angle, wherein the second angle is smaller than the first angle.

The driver 160 further includes a driving shaft 165, the driving shaft 165 is fixedly connected to the driving gear 164, and the driving shaft 165 is further fixedly connected to the bracket 150. When the driving gear 164 rotates, the driving shaft 165 rotates to drive the bracket 150 to rotate, and when the bracket 150 rotates, the driving shaft further drives the first antenna 110 disposed on the bracket 150 to rotate.

Further, the driver 160 further includes a bearing 166, the bearing 166 is sleeved on the driving shaft 165, and the driving gear 164 is connected to the driving shaft 165 through the bearing 166.

The user terminal device 1 further comprises a circuit board 180. The signal conversion device 120 and the processor 130 in the user terminal device 1 are both disposed on the circuit board 180. The circuit board 180 is also referred to as a platelet. The components for driving the first antenna 110 to operate are mainly disposed on the circuit board 180. For example, the circuit board 180 may further be provided with a power supply circuit, a protection circuit, and the like, so as to assist the signal conversion device 120 to convert the first network signal into the WiFi signal.

The step angle is a mechanical angle that the output shaft of the drive motor 161 rotates for one pulse of the control signal. The pitch angle of the drive motor 161 may be, but is not limited to, 3 °, 1.5 °, 0.75 °, 3.6 °, or 1.8 °. The larger the step angle, the larger the angle by which an output shaft of the driving motor 161 rotates due to one pulse of the control signal, the larger the angle by which the first antenna 110 is driven to rotate; conversely, the smaller the step angle, the smaller the angle by which an output shaft of the driving motor 161 is rotated by one pulse of the control signal, the smaller the angle by which the first antenna 110 is rotated. When the step angle is larger, one pulse of the control signal causes the output shaft of the driving motor 161 to rotate by a larger angle, and the output shaft of the driving motor 161 needs to rotate by one circle with fewer pulses; conversely, when the step angle is smaller, one pulse of the control signal causes the output shaft of the drive motor 161 to rotate by a smaller angle, and the output shaft of the drive motor 161 needs to rotate by one turn more pulses. For example, for a drive motor 161 with a step angle of 1.8 °, the number of pulses required for one revolution is 360/1.8 — 200. Generally speaking, the step angle of the driving motor 161 is larger, if the reducer 162 is not adopted, and if the driving motor 161 is directly adopted to drive the bracket 150, the angle of each rotation of the bracket 150 is larger, then the angle of each rotation of the first antenna 110 arranged on the bracket 150 is larger, which further causes the number of the first network signals received by the first antenna 110 during one rotation cycle to be smaller, and further may cause the following inaccurate judgment of the first network signal with the strongest signal according to the signal strength of each acquired first network signal. For example, when the step angle of the rotation of the driving motor 161 is a first angle and the reducer 162 is not used, one pulse of the control signal causes the bracket 150 to rotate from the position a to the position B, and the direction of the first network signal with the strongest signal is located at the position C between the position a and the position B, then, because the step angle is too large, the driving motor 161 cannot drive the first antenna 110 to rotate to the point C, and further, the judgment of the first network signal with the strongest signal according to the signal strength of each acquired first network signal is inaccurate.

The speed reducer 162 is arranged in the user terminal device 1, the first angle is converted into a smaller second angle, and when the driving motor 161 drives the support 150 through the speed reducer 162, the support 150 can rotate for a circle for a plurality of times. In other words, compared with the user terminal device 1 that does not use the reducer 162, the reducer 162 is adopted in this embodiment, so that the first antenna 110 can receive the first network signals in more directions, and the accuracy of determining the first network signal with the strongest signal according to the signal strength of each acquired first network signal is further improved.

The second gear 1632 of the second stage gear set 163b engages the drive gear 164. The radius of the first gear 1631 in the first stage gear set 163a is smaller than the radius of the first gear 1631 in the second stage gear set 163, and the radius of the first gear 1631 in the second stage gear set 163b is smaller than the radius of the driving gear 164.

For purposes of the description, 3-stage gear set 163 is named first stage gear set 163a, second stage gear set 163b, and third stage gear set 163c, respectively. A first gear 1631 of the first stage gear set 163a engages the output shaft of the motor, and a second gear 1632 of the first stage gear set 163a engages the first gear 1631 of the second stage gear set 163 b.

When the number of the gear sets 163 is larger, the smaller the second angle is, the more the accurate control of the rotation angle of the bracket 150 is facilitated, the more the first network signals in more directions are received, and the accuracy of judging the first network signal with the strongest signal according to the signal strength of each acquired first network signal is further facilitated. However, the more gear sets 163, the more time is required for installation of the gear sets 163, and the more space is occupied by the gear sets 163.

Referring to fig. 15 and 16 together, fig. 15 is a schematic structural diagram of a user terminal device according to still another embodiment of the present application; fig. 16 is a top view of fig. 15. The user terminal device 1 of the present embodiment further includes a heat sink 190. The user terminal device 1 comprising the heat sink 190 may be incorporated into the user terminal device 1 provided in any of the previous embodiments. The first antenna 110 comprises a receiving face 111 for receiving the first network signal. The user terminal device 1 further comprises a heat dissipation element 190, wherein the heat dissipation element 190 is directly or indirectly arranged on a surface of the first antenna 110 facing away from the receiving surface 111.

The heat sink 190 may be made of, but not limited to, metal with good thermal conductivity. The heat dissipation member 190 is used for dissipating heat when the first antenna 110 operates, so as to prevent the first antenna 110 from being unstable in performance due to overheating when the first antenna 110 operates. In the present embodiment, the heat sink 190 further includes a plurality of heat dissipation fins 191, and the plurality of heat dissipation fins 191 are spaced apart from each other to improve a heat dissipation effect. Further, the size of the heat sink 191 adjacent to the rotation axis of the first antenna 110 is larger than the size of the heat sink 191 away from the rotation axis.

Since a gap exists between the two ends of the first antenna 110 and the housing 220 of the user terminal device 1, the two ends of the first antenna 110 are more easily cooled than the portion of the first antenna 110 close to the rotation axis. In the user terminal device 1 of the present application, the size of the heat radiation fins 191 adjacent to the rotation axis of the first antenna 110 is set larger than the size of the heat radiation fins 191 distant from the rotation axis, and therefore, the uniformity of the heat radiation effect at each part of the first antenna 110 can be improved.

Further, in one embodiment, the length of the heat sink 191 increases in the direction of the rotation axis from the end of the first antenna 110. Such arrangement of the heat sink 191 can improve uniformity of heat dissipation effect at each portion of the first antenna 110, and on the other hand, the heat sink is not likely to contact other components in the user terminal device 1 when the first antenna 110 rotates.

When the number of the selected second antennas 210 is N, the sum of the signal strengths of the selected N second antennas 210 is greater than the sum of the strengths of the third network signals received by any remaining N second antennas 210 of the M second antennas 210.

In an embodiment, the user terminal device 1 further includes a driver 160 and a processor 130, when the first antenna 110 receives a test instruction, the processor 130 controls the driver 160 to drive the bracket 150 to rotate at least one circle compared to the base 140 to obtain signal strengths of the first network signals in various directions, the processor 130 determines a direction with the strongest signal strength according to the signal strengths of the first network signals in various directions, and the processor 130 controls the driver 160 to drive the bracket 150 to rotate to a direction with the strongest signal strength.

The user terminal device 1 has a test state and a working state, and the test state is before the working state. When the user terminal device 1 is in the test state, the first antenna 110 in the user terminal device 1 receives the test signal and determines the direction in which the first network signal strength is strongest. And when the user terminal equipment 1 determines the direction of the strongest first network signal in the test state, entering a working state. In other words, when the user terminal device 1 is in an operating state, the first antenna 110 is at a preset position compared with the base 140, and at this time, the strength of the first network signal received by the first antenna 110 is greater than the strength of the first network signal when the first antenna 110 is at the rest position compared with the base 140.

In one embodiment, the user terminal 1 has a test state and an operating state, and the test state precedes the operating state. The ue 1 further includes a memory 230, where the memory 230 stores a comparison table, where the comparison table includes a correspondence between the location of the ue 1 and a direction of the strongest first network signal strength corresponding to the location of the ue 1, when the ue 1 is in a test state, the first antenna 110 receives a test instruction, the processor 130 compares the current location of the ue 1 with the comparison table, and when the current location of the ue 1 matches the location of the ue 1 in the comparison table, the processor 130 controls the driver 160 to operate according to the comparison table, so that the first antenna 110 is located in the direction of the strongest first network signal strength corresponding to the matched location.

The ue 1 provided in this embodiment can control the driver 160 to operate according to the current location of the ue 1 and the look-up table, so as to quickly drive the first antenna 110 to the direction where the signal strength of the first network signal is strongest.

More generally, the core objective of the software module of the ue described in the embodiments of the present application is to control the rotation of the antenna through a certain algorithm logic according to information such as antenna signal quality, so as to achieve the automatic alignment direction of the high-frequency antenna and achieve the best performance.

The following describes in detail the algorithmic logic of the user terminal device.

Referring to fig. 26, fig. 26 is a schematic flowchart of an antenna direction calibration method provided in an embodiment of the present application, and is applied to a user terminal device, where the user terminal device includes a first antenna; as shown, the antenna direction calibration method includes the following operations.

S2601, the user terminal device controls the first antenna to rotate to a plurality of directions to perform signal measurement with the first base station alternately, and a plurality of measurement results are obtained.

The first antenna may be, for example, an antenna supporting a 5G network system.

The triggering condition for antenna direction selection control of the user terminal device may be power-on, recalibration due to environmental change (for example, the device is moved, a space where a signal transmission link of the device is located is blocked, etc.), power-off reconnection, etc., which is not limited herein.

The multiple directions may be determined according to a unidirectional coverage range (determined by an antenna design range and a spectral characteristic) and an omnidirectional coverage principle of the first antenna, that is, a total coverage range of the first antenna in the multiple directions should satisfy an omnidirectional coverage condition. The omni-directional coverage principle is constrained with respect to the rotation capability of the first antenna, and if the first antenna only supports rotation in a single plane, the omni-directional coverage principle herein means that the coverage area of the first antenna is omni-directional coverage in the current plane, and if the first antenna supports horizontal and pitching rotation, the omni-directional coverage principle herein means omni-directional coverage in a three-dimensional space.

For example, if the first antenna only supports horizontal rotation and the unidirectional coverage of the first antenna is 180 degrees, the plurality of directions at least include 2 directions (corresponding to an angular interval of 180 degrees), 3 directions (corresponding to an angular interval of 120 degrees), and 4 directions (corresponding to an angular interval of 90 degrees).

In a specific implementation, the multi-direction rotation strategy includes:

rotating step by step to each direction in a plurality of directions according to a preset rotation angle sequence; alternatively, the first and second electrodes may be,

and rotating to each direction in a plurality of directions in a non-sequence mode according to a direction coherence low principle.

If sequential stepping is adopted, the stepping angles in each step may be the same or different. If the same step angle is adopted, the step angle may be determined according to the number of directions in multiple directions, as shown in fig. 27A, for example, the step angle corresponding to 2 directions is 180 degrees (corresponding to the direction 1 to the direction 2 in the first circle of fig. 27A), the step angle corresponding to 3 directions is 120 degrees (corresponding to the direction 1 to the direction 2 and the direction 2 to the direction 3 in the second circle of fig. 27A), the step angle corresponding to 4 directions is 90 degrees (corresponding to the direction 1 to the direction 2, the direction 2 to the direction 3 and the direction 3 to the direction 4 in the third circle of fig. 27A), and so on. It can be seen that this mechanism is simple to implement, and has gain for omnidirectional search, but since the directivity before and after rotation is not too large, the same result may be searched, and the search speed is not optimal.

If the principle of low directional coherence is adopted, the rotation is not sequential, as shown in fig. 27B, under the design that one step angle is less than 120 degrees, that is, the antenna has 4 or more directions to select, when stepping from one direction to the next direction, the rotation is not sequential, but direct to the next detection direction of low coherence, for example, as shown in fig. 27B, 4 directions (from direction 1 to direction 2, direction 2 to direction 3, and direction 3 to direction 4) in the first circle, and 5 directions (from direction 1 to direction 2, direction 2 to direction 3, direction 3 to direction 4, and direction 4 to direction 5) in the second circle as shown in fig. 27B. Therefore, the direction coherence of the two steps is minimum, so that the direction coverage can be quickly finished, and when the optimal cell is judged by self, judgment can be directly initiated after a certain detection direction is searched, so that the network searching speed is improved.

S2602, the user terminal device determines a target direction according to the plurality of measurement results.

And when the user terminal equipment corresponding to the target direction is at the current position, selecting the target direction to perform network access with optimal performance.

S2603, the ue controls the first antenna to rotate to the target direction to complete antenna direction calibration.

In a specific implementation, if the position of the user terminal device after determining the target direction is already in the target direction, the user terminal device only needs to control the local terminal device to maintain the current antenna direction. If the position of the user terminal device is in other directions after the target direction is determined, the user terminal device only needs to control the home terminal device to rotate from the other directions to the target direction.

In one possible example, the first antenna is a millimeter wave antenna; the first base station is a base station in an independent networking SA; the user terminal device further comprises a second antenna for providing basic data services in a preset frequency band lower than the millimeter wave frequency band.

In this possible example, before the controlling the first antenna to rotate to multiple directions to perform signal measurement with the first base station, and obtain multiple measurement results, the method further includes: and interacting with the first base station to initiate a 5G NR network access process in the preset frequency band and successfully residing.

In one possible example, the first antenna is a millimeter wave antenna; the first base station is a base station in a non-independent networking NSA; the user terminal equipment also comprises a third antenna for initiating a fourth generation mobile communication technology 4G long term evolution LTE network access process.

In this possible example, before the controlling the first antenna to rotate to multiple directions to perform signal measurement with the first base station, and obtain multiple measurement results, the method further includes: and initiating a 4G LTE network access process with the first base station and residing successfully.

In one possible example, the controlling the first antenna to rotate to multiple directions to perform signal measurement with the first base station, and obtaining multiple measurement results includes: controlling the first antenna to rotate to each of a plurality of directions, for which the following is performed: and in the measurement period of the current direction, interacting with the first base station to execute the signal measurement of the current direction to obtain the measurement result of the current direction.

In one possible example, only the last measurement result of the plurality of measurement results is that the signal quality satisfies a condition; the determining a target direction from the plurality of measurements comprises: and determining the direction corresponding to the last measurement result as a target direction.

The user terminal device may be preconfigured with a decision condition of the target direction (for example, if the decision condition is greater than the threshold, the condition is satisfied), or a network side (base station) is preconfigured, and the network searching stops rotating after the signal quality satisfies the condition, and directly initiates access and subsequent calibration.

As can be seen, in this example, since the antenna directions meeting the condition are distributed probabilistically, the target direction can be determined in advance to a certain extent, and the antenna direction calibration speed is increased, thereby increasing the 5G network access speed, compared with the omni-directional traversal mechanism.

In one possible example, the measurement periods of the plurality of directions are determined by a standard measurement period configured by the first base station; the standard measurement period is a general measurement period appointed by a standard protocol.

In one possible example, the measurement periods of the plurality of directions are determined by an extended measurement period configured by the first base station; the extended measurement period is a dedicated measurement period customized for the device type of the user terminal device; and the equipment type is reported to the first base station through a capability indication.

In one possible example, the first antenna includes a plurality of receiving modules;

In one possible example, the determining a target direction from the plurality of measurements comprises: reporting the measurement results in the multiple directions to the first base station, wherein the first base station decides the target direction and sends the target direction to the user terminal equipment; receiving the target direction from the first base station.

In one possible example, the determining a target direction from the plurality of measurements comprises: determining a target measurement result with optimal signal receiving quality according to the plurality of measurement results; and determining the rotating direction corresponding to the target measurement result as a target direction.

In one possible example, the process of interacting with the first base station for signal measurement does not include operation of network access.

After the user terminal device obtains the measurement result not in the last measurement, the cell access is not performed, namely, only the measurement is performed, then the rotation measurement is continued, the target direction is determined, and the cell access is performed finally.

In this possible example, after the controlling the first antenna to rotate to the target direction to complete the antenna direction calibration, the method further comprises: receiving a fifth generation mobile communication technology 5G network access command from the first base station; and initiating a 5G network access process according to the 5G network access command.

In one possible example, the signal quality parameters involved in the signal measurement interacting with the first base station include a first signal quality parameter during cell measurement and a second signal quality parameter after cell access.

The user terminal equipment searches for the cell and then directly accesses the cell, acquires the accessed cell and then forcibly quits the cell, and continues to access the next cell according to the rotation strategy, so that the full search can be completed in each direction, or the rotation is stopped after the threshold is met, and the cell in the optimal direction is selected to access again. The advantage of this scheme is that the signal is optimal, but the network searching speed is slow.

The second signal quality parameter may be an index other than the first signal quality parameter, which is determined by signaling interaction between the ue and the first base station after the ue accesses the cell, such as an accessibility index (e.g., RRC connection establishment success rate, EPS attach success rate, average RRC connection establishment duration), a retainability index (e.g., radio drop rate), and an integrity index (e.g., bit rate of user plane uplink/downlink PDCP layer, packet loss rate of user plane downlink PDCP layer, average time delay of user plane downlink PDPC layer).

Therefore, in this example, the user terminal device performs cell access and obtains the second signal quality parameter for each direction in which an effective cell signal is detected, so that more accurate performance judgment is performed by synthesizing the total information, and the accuracy of antenna calibration is improved.
