[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying 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 although the functional components are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a manner different from the component division in the device or the order in the flow chart. The terms "first", "second", etc. in the specification and claims and the above drawings are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0028] The present application provides a terminal device and a control method thereof, and a computer readable storage medium. The signal detection component can detect the interference signal obtained from the antenna through the coupler, thereby obtaining the interference signal strength value of each radio frequency link. Then, the control component determines the interference degree of the radio frequency link according to the interference signal strength value, i.e. the degree of influence of the interference on each radio frequency link can be understood, so that a suitable radio frequency link can be selected from all radio frequency links as a master set receiving channel. Therefore, the anti-interference capability of the terminal device in the multi-channel working mode can be improved, the communication capability of the terminal device can be improved, and the throughput performance of the terminal device can be improved.

[0029] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0030] As shown in FIG. 1, a terminal device 1 includes a signal detection component 10, a control component 20, a coupler 30, and a plurality of radio frequency links 40. Figure 1 The signal detection component 10 is configured to detect the interference signal obtained from the antenna through the coupler 30, thereby obtaining the interference signal strength value of each radio frequency link 40. Figure 1is a schematic diagram of a terminal device provided by an embodiment of the present application.

[0031] In Figure 1 the example, the terminal device includes two radio frequency links 100, the radio frequency link 100 including an antenna 110, a coupler 120, and a signal detection component 130 for detecting the power intensity of an interference signal, the coupler 120 being provided with a first signal end IN, a second signal end OUT, a first coupling end CPL, and a second coupling end TERM, the signal detection component 130 being provided with a signal input end T1 and a signal output end T2, the second signal end OUT being connected with the antenna 110, and the second coupling end TERM being connected with the signal input end T1.

[0032] A control component 200 is connected with the first signal end IN, the first coupling end CPL, and the signal output end T2 respectively, for determining the interference degree of the radio frequency link 100 according to the interference signal intensity value sent by the signal detection component 130, and for selecting the radio frequency link 100 as the main set receiving channel from the two radio frequency links 100 according to the interference degrees of the respective radio frequency links 100, wherein the interference signal intensity value is obtained by the signal detection component 130 detecting the interference signal acquired from the antenna 110 through the coupler 120.

[0033] It should be noted that, since the structures and working modes of the two radio frequency links 100 are the same, to avoid redundancy, only the specific structure of one radio frequency link 100 is shown in Figure 1 , and accordingly, the specific structure of the other radio frequency link 100 (i.e. the structure formed by the BLOCK shown in Figure 1 and the antenna 110) can be obtained therefrom.

[0034] In an embodiment, the signal detection component 130 can detect the interference signal acquired from the antenna 110 through the coupler 120, thereby obtaining the interference signal intensity value of the respective radio frequency link 100, since the interference signal intensity value of the radio frequency link 100 is related to its interference degree, i.e. the greater the interference signal intensity value, the greater the interference degree of the radio frequency link 100, thus the interference degree of the radio frequency link 100 can be determined according to the interference signal intensity value, and when the interference degrees of the respective radio frequency links 100 are determined, the appropriate radio frequency link 100 can be selected as the main set receiving channel from all the radio frequency links 100 according to the influence, thus the anti-interference capability of the terminal device in the multi-channel working mode can be improved, the communication capability of the terminal device can be improved, and thus the throughput performance of the terminal device can be improved.

[0035] In an embodiment, "main set reception" and "diversity reception" are two technical terms in the art, the antenna 110 in the radio frequency link 100 as a main set reception channel is mainly responsible for the transmission and reception of radio frequency signals, accordingly, the antenna 110 in the radio frequency link 100 as a diversity reception channel is generally only responsible for receiving signals and not transmitting signals, and finally the base station will combine the signals received from the two channels, it can be seen that when the radio frequency link 100 selected according to the interference level of each radio frequency link 100 is determined as a main set channel for reception, since the interference received by the antenna 110 is improved, it can perform complete transmission and reception procedures on the signal, thereby improving the anti-interference capability of the terminal device in the multi-channel working mode, and further enabling the base station to obtain corresponding gain.

[0036] In an embodiment, the terminal device can be, but is not limited to, a 5G terminal device, and can also be a product associated with the 5G terminal device, such as a 5G network peripheral device, a 5G network module, a 5G network chip, a 5G network data platform, a mobile broadband product, or an Internet of Things product, etc., and whether it is a 5G terminal device or a product associated with the 5G terminal device, it can support setting in a non-standalone (Non-Standalone, NSA) or standalone (Standalone, SA) mode, and can also be set in all scenarios supporting sounding reference signals (Sounding Reference Signal, SRS); or the terminal device can also be a customer premise equipment (Customer Premise Equipment, CPE) in a wireless network, that is, a wireless router device.

[0037] In an embodiment, according to the application of the terminal device in different scenarios in practice, the number of radio frequency links 100 can also be set to any value greater than two, which is not limited in this embodiment.

[0038] In an embodiment, the control component 200 can be specifically configured to determine the radio frequency link 100 with the largest interference degree from the two radio frequency links 100 according to the interference degrees of the respective radio frequency links 100, and select any one radio frequency link 100 except the radio frequency link 100 with the largest interference degree as the radio frequency link 100 of the main set receiving channel. Since the radio frequency link 100 with the largest interference degree significantly affects the performance of the antenna 110, it can be determined that it is not suitable to be the radio frequency link 100 of the main set receiving channel, and then the radio frequency link 100 with the smallest interference degree can be selected from the two radio frequency links 100. Thus, the radio frequency link 100 corresponding to the antenna 110 with the smallest interference degree can be set as the radio frequency link 100 of the main set receiving channel, thereby improving the anti-interference capability of the terminal device in the multi-channel working mode and improving the throughput performance of the terminal device.

[0039] In an embodiment, the control component 200 can also be specifically configured to select the radio frequency link 100 with the smallest interference degree from the two radio frequency links 100 as the radio frequency link 100 of the main set receiving channel according to the interference degrees of the respective radio frequency links 100. The antenna 110 corresponding to the radio frequency link 100 with the smallest interference degree has the smallest interference degree, and thus the radio frequency link 100 is suitable to be the radio frequency link 100 of the main set receiving channel, thereby improving the anti-interference capability of the terminal device in the multi-channel working mode and improving the throughput performance of the terminal device.

[0040] In an embodiment, the model and specification of the coupler 120 are not limited, and can be selected according to actual conditions. However, no matter how, the coupler 120 can be switched to a coupling mode for obtaining the antenna 110 signal, and in this case, the signal flow direction is in sequence through: the antenna 110, the second signal end OUT, the second coupling end TERM, the signal input end T1, the signal output end T2 and the control component 200. In this process, part of the signal also directly returns to the control component 200 through the first coupling end CPL, but does not affect the detection of the antenna 110 signal. In addition, the coupler 120 can also be switched to a coupling mode for transmitting the antenna 110 signal, and in this case, the signal flow direction is in sequence through: the control component 200, the first signal end IN, the second signal end OUT and the antenna 110. It can be seen that the embodiment can not only be used to obtain the antenna 110 signal for detection, but also can couple and output the antenna 110 signal, and thus has a certain versatility, which can improve the use effect of the mobile terminal.

[0041] In one embodiment, the terminal device is further provided with a link switch. The link switch has a link switch input terminal connected to the control component 200, a link switch output terminal connected to each RF link 100 respectively, and a link control terminal connected to the control component 200. When the control component 200 selects the RF link 100 as the main receiving channel from the two RF links 100 according to the interference level of each RF link 100, it only needs to turn on the corresponding link switch output terminal through the link control terminal to realize the conduction switching of the RF link 100 as the main receiving channel. It should be noted that in practical applications, multiple link switches can be provided. The conduction switching of the RF link 100 as the main receiving channel can also be realized through multiple link switches. The basic principle is the same as that in the above embodiment. To avoid redundancy, it will not be described in detail here.

[0042] In one embodiment, the terminal device is further provided with a power amplifier connected to the control component 200. When the acquired antenna 110 signal is distorted, the power amplifier can amplify the power of the antenna 110 signal corresponding to the RF link 100, which serves as the main receiving channel, thereby improving the communication effect of the RF link 100, which serves as the main receiving channel, and thus improving the throughput performance of the terminal device.

[0043] In one embodiment, the control component 200 is provided with a radio frequency (RF) input terminal and a feedback output terminal. The RF input terminal is connected to a first signal terminal, and the signal output terminal is connected to the feedback output terminal. Signal transmission can be achieved between the RF input terminal and the coupler. The interference signal strength value from the signal output terminal can be obtained through the feedback input terminal. It can be seen that providing an RF input terminal and a feedback output terminal can enable the control component 200 to work more stably and reliably, which is beneficial to improving its working stability.

[0044] Furthermore, such as Figure 2 As shown, Figure 2 This is a schematic diagram of a terminal device provided in another embodiment of the present invention.

[0045] exist Figure 2 In the example, the signal detection component includes a filtering module 131 for filtering the interference signal obtained from the antenna 110 through the coupler 120 and a detection module 132 for detecting the signal strength of the filtered interference signal; the filtering module 131 is provided with a filtering input terminal A1 and a filtering output terminal A2, and the detection module 132 is provided with a detection input terminal B1 and a detection output terminal B2. The filtering input terminal A1 is connected to the signal input terminal T1, the filtering output terminal A2 is connected to the detection input terminal B1, and the detection output terminal B2 is connected to the signal output terminal T2.

[0046] In an embodiment, the filtering module 131 obtains the corresponding interference signal through the filtering input end A1 and can filter the interference signal, and then outputs the filtered interference signal through the filtering output end A2. Since the impurity components in the filtered interference signal are basically filtered out, the performance of the filtered interference signal is more stable. When the detection module 132 receives the filtered interference signal and detects it, the interference signal strength value can be stably measured, that is, the interference situation in the antenna 110 can be accurately and reliably known, so that the control assembly 200 can accurately select the radio frequency link 100 as the main set receiving channel from the two radio frequency links 100.

[0047] In an embodiment, the filtering module 131 can adopt various types or specifications of filters, and the detection module 132 can be a related circuit for power detection of the filtered interference signal, that is, the filtered interference signal can be digitized by power detection, so as to obtain a digital signal corresponding thereto, and the signal strength thereof can be directly obtained through the digital signal. In addition, the detection module 132 can also include an amplification circuit. For example, after obtaining the digital signal, if the gain, power, etc. of the converted digital signal is distorted, the detection module 132 can amplify the digital signal and supply it to the control assembly 200, so that the control assembly 200 can more easily identify the amplified digital signal and determine the interference degree of the radio frequency link 100 according to it.

[0048] Further, as shown in Figure 3 , Figure 3 is a schematic diagram of a terminal device provided by another embodiment of the present application.

[0049] In Figure 3 the example, the number of filtering modules 131 is multiple, and each filtering module 131 has a different filtering frequency band; the signal detection assembly further includes a first switch 140, which is provided with a first switch input end D1, a first switch output end D2 and a first control end. The first switch input end D1 is connected to the signal input end T1, the first control end is connected to the control assembly 200, and the number of first switch output ends D2 is consistent with the number of filtering modules 131. The first switch output end D2 is connected to the filtering input end A1.

[0050] In an embodiment, the control component 200 can obtain the frequency band information of the interference signal in the antenna 110 through the first signal end IN or the first coupling end CPL, and feed back the information to the first switch 140 corresponding to the information through the first control end, and only control the first switch 140 to open, so that the filter module 131 corresponding to the filter frequency band is turned on to filter and output the interference signal. It can be seen that the first switch 140 can be regarded as a turn-on element with multiple switch ports, and through this control mode, only the filter module 131 of the corresponding filter frequency band can be controlled to be turned on, and the filter module 131 will not be mistakenly turned on, that is, no useless filtering will be performed on other signals except the interference signal, and stable and reliable filtered interference signals can be ensured to be output.

[0051] In an embodiment, the signal detection component further comprises a second switch 150, which is provided with a second switch input end C1, a second switch output end C2 and a second control end. The second switch output end C2 is connected to the detection input end B1, the second control end is connected to the control component 200, the number of the second switch input end C1 is consistent with the number of the filter module 131, and the second switch input end C1 is connected to the filter output end A2. The second switch 150 can be separately provided relative to the first switch 140, or can be cooperatively provided with the first switch 140 at both ends of the filter module 131. The technical effects of the second switch 150 are consistent, for example, in the example of Figure 3 In addition to the first switch 140, the second switch 150 is also provided. When the filter module 131 corresponding to the filter frequency band is turned on to filter and output the interference signal, the second switch input end C1 corresponding to the filter module 131 can be controlled to be turned on, so as to output the filtered interference signal to the detection module 132. Through this control mode, only the filtered interference signal will be output from the filter output end A2 of the corresponding frequency band, and the filtered interference signal will not be mistakenly output, so that the detection module 132 can stably obtain the filtered interference signal.

[0052] In an embodiment, the timing of controlling the first switch 140 to be opened and the corresponding filter module 131 to be filtered can be set as a specific interval in the signal working and transmission process of the antenna 110, such as a time slot in the NR mode of 5G. Such a detection mode will not cause excessive influence on the working and transmission of the antenna 110, or the corresponding timing can be set by the person skilled in the art according to the actual situation to control the first switch 140 to be opened and the corresponding filter module 131 to be filtered.

[0053] Further, as shown in Figure 4 , the Figure 4 is a schematic diagram of a terminal device provided by another embodiment of the present application.

[0054] In Figure 4 the example, the radio frequency link 100 further comprises a third switch 160, the first coupling end CPL is connected to the control component 200 through the third switch 160.

[0055] In an embodiment, the third switch 160 can be a single-pole double-throw switch, in which the third switch 160 is provided with a third switch input end and a third switch output end capable of switching, the third switch input end is connected to the first coupling end CPL; when the coupler 120 is in the coupling mode of transmitting the antenna signal, the third switch output end is connected to the control component 200, thereby playing an auxiliary coupling role; in another case, when the coupler 120 is in the coupling mode of receiving the antenna signal, the third switch output end is switched to be connected to the ground through a load, thereby realizing impedance matching, and also preventing part of the antenna signal input from the second signal end from being received by the first coupling end CPL, so as to avoid affecting the detection accuracy of the interference signal.

[0056] In an embodiment, the third switch 160 can also be various types of relays, the relay is provided with a contact switch, one end of the contact switch is connected to the first coupling end CPL, and the other end can be switched between being connected to a load and being connected to the control component 200, thereby also playing the same role as the above-mentioned embodiment, which will not be repeated here.

[0057] In an embodiment, the radio frequency link 100 can further comprise a fourth switch 170, the second coupling end TERM is connected to the signal input end T1 through the fourth switch 170, wherein the fourth switch 170 can be separately provided relative to the third switch 160, or can be cooperatively provided with the third switch 160 at both ends of the coupler 120, and the technical effects achieved by the fourth switch 170 are consistent, such as, in Figure 4In the example, in addition to the third switch 160, a fourth switch 170 is further provided, and the third switch 160 can also be a single-pole double-throw switch or a relay of various types. When the fourth switch 170 is a single-pole double-throw switch, the fourth switch 170 is provided with a fourth switch input end and a fourth switch output end capable of switching, and the fourth switch input end is connected to the second coupling end TERM. When the coupler 120 is in the coupling mode of transmitting an antenna signal, the fourth switch output end is connected to the ground through a load, so as to realize impedance matching, and also can prevent part of the antenna signal output from the first signal end IN from being received by the second coupling end TERM, so as to avoid affecting the transmission strength of the antenna signal. In another case, when the coupler 120 is in the coupling mode of receiving an antenna signal, the fourth switch output end is switched to be connected to the signal input end T1, and plays an auxiliary coupling role. It should be noted that the first coupling end CPL or the second coupling end TERM can be adaptively adjusted according to the actual situation of the radio frequency link 100, and this is not limited in the embodiment.

[0058] In an embodiment, the third switch 160 or / and the fourth switch 170 can assist the radio frequency link 100 to work. Compared with the related art, no additional active device or / and passive device needs to be added in the radio frequency link 100 to assist in the embodiment, so that the insertion loss caused by the additional device can be reduced, and the material cost of the radio frequency link 100 is also saved.

[0059] Referring to Figure 5 , Figure 5 is a schematic diagram of a terminal device 300 provided by another embodiment of the present application.

[0060] As Figure 5 shown, the terminal device 300 includes one or more control processors and memories, Figure 6 In an embodiment, one control processor and one memory are taken as an example.

[0061] The control processor and the memory can be connected through a bus or other means, Figure 6 In an embodiment, connection through a bus is taken as an example.

In addition, the memory can include high-speed random access memory and can also include non-transitory memory, such as at least one magnetic disk storage device, a flash memory device, or other non-transitory solid-state memory device. In some embodiments, the memory can optionally include remote memory that is remotely disposed relative to the control processor, which can be connected to the control processor through a network. Examples of the above network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0065] In Figure 5 In the terminal device 300 shown in the above-mentioned figures, the control processor can execute the corresponding terminal device 300 control method based on the instructions stored in the internal memory of the terminal device 300.

[0066] Since the terminal device 300 in the present embodiment and the terminal device 300 in the above-mentioned embodiments belong to the same inventive concept, the specific embodiments of the terminal device 300 in the present embodiment can refer to the specific embodiments of the terminal device 300 in the above-mentioned embodiments. To avoid redundancy, the specific embodiments of the terminal device 300 in the present embodiment will not be described here.

[0067] Based on the structure of the above-mentioned terminal device 300, each embodiment of the terminal device 300 control method of the present application is proposed.

[0068] As Figure 6 shown, Figure 6 is a flowchart of the terminal device control method provided by an embodiment of the present application, which can be applied to the terminal device as shown in Figure 1 or Figure 5 The method includes but is not limited to:

[0069] In step S100, for each radio frequency link, an interference signal strength value sent by the signal detection component is acquired, and the interference degree of the current radio frequency link is determined according to the interference signal strength value, wherein the interference signal strength value is obtained by the signal detection component detecting the interference signal obtained from the antenna through the coupler.

[0070] In step S200, the radio frequency link serving as the main set receiving channel is selected from the at least two radio frequency links according to the interference degrees of the radio frequency links.

[0071] In an embodiment, for each radio frequency link, the signal detection component can detect the interference signal obtained from the antenna through the coupler, so as to acquire the interference signal strength value of each radio frequency link, and then the control component determines the interference degree of the radio frequency link according to the interference signal strength value, that is, the degree of influence of the interference on each radio frequency link can be understood, so that a suitable radio frequency link can be selected from all the radio frequency links as the main set receiving channel. Therefore, the anti-interference capability of the terminal device in the multi-channel working mode can be improved, the communication capability of the terminal device can be improved, and the throughput performance of the terminal device can be improved.

[0072] It is worth noting that after the radio frequency link serving as the main set receiving channel is selected from the at least two radio frequency links, the terminal device still relies on all the radio frequency links to work simultaneously to realize communication. That is, the embodiment mainly reduces the interference on the radio frequency link serving as the main set receiving channel to improve the anti-interference capability of the terminal device in the multi-channel working mode. Compared with the way of making the mutual interference frequency bands work in time sharing mode by using an algorithm in the related art, the terminal device in the embodiment can work in the multi-channel working mode, so as to have stronger communication transmission capability and higher throughput performance.

[0073] It should be noted that the terminal device control method in the embodiment belongs to the same inventive concept as the terminal device in the above Figure 1 and Figure 6 embodiments, and therefore the other specific embodiments of the terminal device control method in the embodiment can refer to the specific embodiments of the terminal device in the above embodiments. To avoid redundancy, the other specific embodiments of the terminal device control method in the embodiment will not be described here.

[0074] Further, as shown in Figure 7 , step S200 further includes but is not limited to:

[0075] Step S210, determining the radio frequency link with the largest interference degree from the at least two radio frequency links according to the interference degrees of the respective radio frequency links, and selecting any one radio frequency link other than the radio frequency link with the largest interference degree as the radio frequency link of the main set receiving channel from the at least two radio frequency links.

[0076] In an embodiment, since the radio frequency link with the largest interference degree significantly affects the performance of the antenna, it can be determined that it is not suitable to be the main set receiving channel, and then the radio frequency link corresponding to the antenna with smaller interference can be set as the main set receiving channel by removing the radio frequency link with the largest interference degree from the two radio frequency links and selecting the corresponding radio frequency link from the remaining radio frequency links, so as to improve the anti-interference capability of the terminal device in the multi-channel working mode, and improve the throughput performance of the terminal device.

[0077] Further, as shown in Figure 8 , step S200 further includes but is not limited to:

[0078] Step S220, selecting the radio frequency link with the smallest interference degree as the radio frequency link of the main set receiving channel from the at least two radio frequency links according to the interference degrees of the respective radio frequency links.

[0079] In an embodiment, the antenna corresponding to the radio frequency link with the smallest interference degree has the smallest interference degree, so the radio frequency link is suitable to be the main set receiving channel, which can improve the anti-interference capability of the terminal device in the multi-channel working mode, and improve the throughput performance of the terminal device.

[0080] Further, as shown in Figure 9 , the terminal device control method can also be applied to the terminal device as shown in any one of Figures 2 to 5 , and step S100 further includes but is not limited to:

[0081] Step S110, determining the frequency band of the interference signal according to the interference signal obtained from the antenna through the coupler;

[0082] Step S120, determining the target filtering module matched with the interference signal from the plurality of filtering modules according to the frequency band of the interference signal;

[0083] Step S130, controlling the first switch and the second switch to select the target filtering module.

[0084] Step S140, obtaining the interference signal strength value sent by the detection module, which is obtained by the detection module detecting the signal strength of the interference signal passing through the target filtering module.

[0085] In an embodiment, after determining the frequency band where the interference signal is located, a target filtering module matching the interference signal can be determined from the plurality of filtering modules, so that the corresponding ports of the first switch and the second switch can be opened correspondingly, so that only the signal passing through the target filtering module can be conducted (including the input signal and the output signal), and the influence of other signals in the antenna on the detection of the interference signal can be avoided, so that the detection accuracy of the interference signal is greatly improved.
