[0052] b5. In the case of b4, a specific case is included, that is, the second communication system includes four initial second antennas and corresponding four candidate second antennas, wherein each initial second antenna corresponds to the same communication radio frequency path as one candidate second antenna.

[0061] The following is a detailed description of the embodiments in conjunction with the accompanying drawings. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0062] See also Figure 4 The embodiment of the present application provides an antenna selection method, which can be applied to a terminal device or a communication device (such as a chip system) that supports the terminal device to implement the antenna selection method. Specifically, the embodiment of the present application takes the terminal device as an example for explanation. For the sake of simplicity and convenience of description, the execution subject will be omitted in the subsequent method embodiments. Specifically, the method may include steps 201 to 204:

[0063] 201. Transmit a first signal through a first communication system of a first communication standard.

[0064] 202. Transmit a second signal through a second communication system of a second communication standard, where the first communication standard is different from the second communication standard.

[0065] The initial first antenna is configured to transmit the first signal, and the initial second antenna is configured to transmit the second signal.

[0066] In some embodiments, the first communication mode may include: wifi communication, and / or the second communication mode may include: cellular communication. Specifically, the cellular communication in the embodiment of the present application is illustrated by 5G new radio (NR) communication.

[0067] 203. Obtain first signal quality data corresponding to the first signal and second signal quality data corresponding to the second signal.

[0068] The first communication system may include an initial first antenna and at least one candidate first antenna, and the second communication system may include an initial second antenna and at least one candidate second antenna.

[0069] Generally, the terminal device uses the initial antenna to communicate between powering on and performing the first antenna switching operation. Therefore, it can be understood that the first signal is generated or received by the initial first antenna, and the second signal is generated or received by the initial second antenna.

[0070] The signal quality data is a parameter for evaluating the signal quality when the antenna is transmitting signals in a working state. Specifically, the signal quality data may include working signal strength, interference signal strength, and signal-to-noise ratio.

[0071] Specifically, the terminal device obtains first signal quality data corresponding to the first signal and second signal quality data corresponding to the second signal, which may include: when a first communication system of a first communication standard transmits a first signal, scanning an antenna in a working state in the first communication system to obtain first signal quality data corresponding to the first signal; when a second communication system of a second communication standard transmits a second signal, scanning an antenna in a working state in the second communication system to obtain second signal quality data corresponding to the second signal.

[0072] In a specific embodiment, the signal feedback circuit on ANT ABCD couples the antenna signal (corresponding to the first signal) received by each antenna and feeds it back to the signal processing module. The signal processing module periodically processes and analyzes the signal of each antenna to obtain the first signal quality data, which may specifically include the strength of the working signal, the strength of the interference signal, and the signal-to-noise ratio.

[0073] In one embodiment, before obtaining the first signal quality data corresponding to the first signal and the second signal quality data corresponding to the second signal, it also includes: when the terminal device is turned on or when the terminal device receives an initialization instruction, the working state of each antenna is initialized, and each communication system selects the corresponding initial antenna as the default working antenna according to the preset initialization file. For example, the first communication system selects the initial first antenna as the default working antenna, and the second communication system selects the initial second antenna as the default working antenna.

[0074] In the embodiment of the present application, by setting a default working antenna, it is possible to effectively prevent the initial antenna and the candidate antenna from competing with each other, thereby avoiding the technical problem of antenna usage disorder.

[0075] 204. Select a first target antenna and a second target antenna for communication according to the first signal quality data and the second signal quality data, the first target antenna belonging to the first communication system, and the second target antenna belonging to the second communication system.

[0076] The first target antenna and the second target antenna are antennas that can optimize coexistence interference between the first communication system and the second communication system.

[0077] In some embodiments, the step of selecting a first target antenna and a second target antenna for communication based on the first signal quality data and the second signal quality data may specifically include: determining a first target antenna in a first communication system and determining a second target antenna in a second communication system based on the first signal quality data and the second signal quality data; and using the first target antenna and the second target antenna for communication.

[0078] In an embodiment of the present application, based on the first signal quality data and the second signal quality data, a first target antenna and a second target antenna that can optimize the coexistence interference between the first communication system and the second communication system are selected in the first communication system and the second communication system respectively, so that the coexistence interference between the two communication systems of different standards can be effectively and timely reduced, thereby improving the overall communication quality of the terminal device.

[0079] In some embodiments, Figure 5 As shown, the steps of determining the first target antenna in the first communication system and determining the second target antenna in the second communication system according to the first signal quality data and the second signal quality data may specifically include steps 2021 to 2023:

[0080] Step 2021: If the first signal quality data and / or the second signal quality data do not meet the preset signal quality requirement, a first candidate second antenna is determined from at least one candidate second antenna based on a preset antenna switching strategy, and the working states of the initial second antenna and the first candidate second antenna are switched. Specifically, the states of the initial second antenna and the first candidate second antenna are swapped, that is, the state of the initial second antenna is switched from a working state to a non-working state, and the state of the first candidate second antenna is switched from a non-working state to a non-working state.

[0081] Among them, the signal quality requirement can be set according to the specific type of signal quality data. The signal quality data is within the set threshold range as a way to determine whether it meets the requirements. For example, when the signal quality data is the working signal strength, the working signal strength threshold range corresponding to the working signal strength is set accordingly; when the signal quality data is the interference signal strength, the interference signal strength threshold range corresponding to the interference signal strength is set accordingly; when the signal quality data is the signal-to-noise ratio, the signal-to-noise ratio threshold range corresponding to the signal ratio is set accordingly.

[0082] After determining the specific type of the signal quality data and setting the corresponding threshold range, the data are compared to determine whether the specific value of the signal quality data is within the set threshold range. If the specific values ​​corresponding to the first signal quality data and the second signal quality data are both within the set threshold range, it is determined that the signal quality data meets the signal quality requirements. Then, it can be determined that the initial first antenna is the first target antenna and the initial second antenna is the second target antenna. In this way, there is no need to perform subsequent antenna switching operations on the communication system according to a preset antenna switching strategy.

[0083] Among them, the antenna switching strategy is pre-set. Specifically, the antenna switching strategy can be set in the signal processing module. The antenna switching strategy embodies a strategy for selecting an antenna switching method that matches the situation where the signal quality data corresponding to the antenna in the working state in the first communication system and / or the second communication system does not meet the preset signal quality requirements. For example, a first candidate second antenna can be randomly determined from at least one candidate second antenna in the second communication system, and its working state is switched, or a first candidate second antenna can be determined according to a preset empirical rule to select a second target antenna that can optimize the coexistence interference between the first communication system and the second communication system from at least one candidate second antenna, or a first candidate first antenna can be randomly determined from at least one candidate first antenna in the first communication system, and its working state is switched, or a first candidate first antenna can be determined according to a preset empirical rule to select a first target antenna that can optimize the coexistence interference between the first communication system and the second communication system from at least one candidate first antenna.

[0084] It should be noted that when the initial second antenna and at least one candidate second antenna correspond to the same communication radio frequency path, when performing the antenna switching operation, among all the antennas in the same communication radio frequency, only one antenna is in a working state, while the other antennas are in a non-working state. Specifically, the non-working state may be a detection state.

[0085] In a specific embodiment, when the first communication system needs to perform an antenna switching operation, the signal processing module sends a switching instruction to the antenna switching circuit F, and the WIFIDRX can switch from the antenna C to the antenna D.

[0086] In another specific embodiment, the signal feedback circuit feeds back the received signal of each antenna to the signal processing module, and the signal processing module processes and analyzes the received signal to obtain second signal quality data, which may specifically include the strength RSRP / RSSI / SNR of the NR working signal and the size of the interference signal (coexistence interference signal and environmental interference signal); the antenna switching circuit 1-2-3-4 switches between corresponding antennas according to the control signal level given by the signal processing module.

[0087] In some embodiments, when the second communication system includes a communication radio frequency path, the at least one initial second antenna is an initial second antenna, and the initial second antenna and at least one candidate second antenna correspond to a communication radio frequency path; then, performing an antenna switching operation on the second communication system to switch the working state of a first candidate second antenna among at least one of the candidate second antennas may specifically include: switching the state of the initial second antenna from a working state to a non-working state, and switching the state of the first candidate second antenna from a non-working state to a working state.

[0088] Optionally, when the second communication system includes multiple communication radio frequency paths, the at least one initial second antenna includes multiple initial second antennas, the at least one candidate second antenna includes multiple candidate second antennas, the multiple candidate second antennas are divided into multiple groups of candidate second antennas, and each initial second antenna and a corresponding group of candidate second antennas correspond to one communication radio frequency path; then, performing an antenna switching operation on the second communication system to switch the working state of at least one first candidate second antenna among the candidate second antennas may specifically include: selecting a target communication radio frequency path from the multiple communication radio frequency paths, switching the state of the corresponding initial second antenna in the target communication radio frequency path from a working state to a non-working state, and switching the state of the corresponding first candidate second antenna in each target communication radio frequency path from a non-working state to a working state.

[0089] In a specific embodiment, the multiple communication RF paths are four communication RF paths, specifically including PRX, DRX, PRXMIMO, and DRXMIMO, and the selected target communication RF path can be a PRX path, and the PRX path includes an initial second antenna and a candidate second antenna, wherein the initial second antenna is antenna 1, and the candidate second antenna includes only one antenna 2. Then, switching the state of the corresponding initial second antenna in the target communication RF path from a working state to a non-working state, and switching the state of the corresponding first candidate second antenna in each target communication RF path from a non-working state to a working state can specifically include: switching the state of antenna 1 from a working state to a non-working state, and switching the state of antenna 2 from a non-working state to a working state.

[0090] Optionally, when the second communication system includes multiple communication radio frequency paths, the at least one initial second antenna includes multiple initial second antennas, the at least one candidate second antenna includes multiple candidate second antennas, the multiple candidate second antennas are divided into multiple groups of candidate second antennas, and each initial second antenna and a corresponding group of candidate second antennas correspond to one communication radio frequency path; then, performing an antenna switching operation on the second communication system to switch the working state of at least one first candidate second antenna among the candidate second antennas may specifically include: selecting multiple target communication radio frequency paths from the multiple communication radio frequency paths, switching the state of the corresponding initial second antenna in each target communication radio frequency path from a working state to a non-working state, and switching the state of the corresponding first candidate second antenna in each target communication radio frequency path from a non-working state to a working state.

[0091] Among them, the multiple communication RF paths can be two communication RF paths, four communication RF paths or more than four communication RF paths, and the specific number can be set according to actual needs; and the number of multiple target communication RF paths is less than or equal to the total number of multiple communication RF paths, specifically two target communication RF paths, four target communication RF paths or more than four target communication RF paths, and the specific number can be set according to actual needs and is not limited here.

[0092] This embodiment can improve antenna switching efficiency and signal adjustment rate by performing antenna switching on multiple target communication RF paths in multiple communication RF paths in the second communication system, thereby facilitating rapid finding of an antenna that can optimize the coexistence interference between the first communication system and the second communication system.

[0093] Step 2022: Acquire third signal quality data corresponding to the initial first antenna after the antenna switching operation and fourth signal quality data corresponding to the first candidate second antenna.

[0094] When the initial second antenna is switched to the first candidate second antenna, the interference between the first communication system and the second communication system changes, so that the signal transmission condition of the initial first antenna changes accordingly, such as the interference signal strength changes, the signal-to-noise ratio changes, etc.

[0095] Therefore, this embodiment obtains the third signal quality data corresponding to the initial first antenna after the antenna switching operation and the fourth signal quality data corresponding to the first candidate second antenna, and re-analyzes the signals of the antennas in working state in the first communication system and the second communication system, so as to further determine the first target antenna in the first communication system and the second target antenna in the second communication system.

[0096] Step 2023: Determine a first target antenna in the first communication system and a second target antenna in the second communication system based on the third signal quality data and the fourth signal quality data.

[0097] In some embodiments, based on the third signal quality data and the fourth signal quality data, determining the first target antenna in the first communication system and determining the second target antenna in the second communication system include: determining whether the third signal quality data and the fourth signal quality data both meet the preset signal quality requirements; if the third signal quality data and the fourth signal quality data both meet the preset signal quality requirements, determining the initial first antenna as the first target antenna and the first candidate second antenna as the second target antenna.

[0098] However, after the above antenna switching operation, there is a situation where the preset signal quality requirement is still not met.

[0099] To this end, in some embodiments, the method may further include: if the third signal quality data and / or the fourth signal quality data do not meet the preset signal quality requirements, then based on the antenna switching strategy, determine a second candidate second antenna different from the first candidate second antenna from at least one candidate second antenna, and switch the working states of the first candidate second antenna and the second candidate second antenna. Specifically, the states of the first candidate second antenna and the second candidate second antenna are interchanged, that is, the state of the first candidate second antenna is switched from the working state to the non-working state, and the state of the second candidate second antenna is switched from the non-working state to the non-working state. Then, the fifth signal quality data corresponding to the initial first antenna after the antenna switching operation and the sixth signal quality data corresponding to the second candidate second antenna are obtained. Based on the fifth signal quality data and the sixth signal quality data, the first target antenna is determined in the first communication system, and the second target antenna is determined in the second communication system.

[0100] The at least one candidate second antenna includes a plurality of candidate second antennas, and the second candidate second antenna is an antenna different from the first candidate second antenna among the plurality of candidate second antennas.

[0101] In the embodiment of the present application, when the communication work of selecting the first candidate second antenna to replace the initial second antenna still does not meet the requirements, a second candidate second antenna different from the first candidate second antenna is selected from multiple candidate second antennas to replace the first candidate second antenna, thereby increasing the probability of acquiring the first target antenna and the second target antenna and improving the coexistence probability of two communication systems with different standards.

[0102] Furthermore, based on the technical solution of selecting a second candidate second antenna different from the first candidate second antenna from multiple candidate second antennas to replace the first candidate second antenna given in the above embodiment, the method may also include: selecting new candidate second antennas different from the previously switched one from the multiple candidate second antennas in turn to replace the old candidate second antenna selected last time, until the first target antenna and the second target antenna are determined that can optimize the coexistence interference between the first communication system and the second communication system.

[0103] In the embodiment of the present application, by exhaustively switching antennas for all candidate second antennas, a first target antenna and a second target antenna that can optimize the coexistence interference between the first communication system and the second communication system can be determined with a higher probability from the first communication system and the second communication system.

[0104] In some embodiments, based on the fifth signal quality data and the sixth signal quality data, the steps of determining the first target antenna in the first communication system and determining the second target antenna in the second communication system may specifically include: determining whether the fifth signal quality data and the sixth signal quality data both meet the preset signal quality requirements; if the fifth signal quality data and the sixth signal quality data both meet the preset signal quality requirements, determining the initial first antenna as the first target antenna and the second candidate second antenna as the second target antenna.

[0105] It should be noted that since the mutual interference between two communication systems of different standards is related to the antennas that are actually in a working state, simply by performing signal analysis on the antennas that are in a non-working state, the signal analysis results obtained will have a large error with the signal analysis results after the actual switching. In this regard, the embodiment of the present application performs an actual antenna switching operation on the second communication system based on the antenna switching strategy, and performs signal analysis on the antenna after switching until the first target antenna and the second target antenna that can optimize the coexistence interference between the first communication system and the second communication system are obtained.

[0106] However, after the second communication system switches the antenna, there may still be a situation where the preset signal quality requirements are not met. To this end, in some embodiments, the first communication system may include at least one candidate first antenna. The method may also include: if the fifth signal quality data and / or the sixth signal quality data do not meet the preset signal quality requirements, then based on the preset antenna switching strategy, determine a first candidate first antenna from at least one candidate first antenna, and switch the working states of the initial first antenna and the first candidate first antenna. Specifically, the states of the initial first antenna and the first candidate first antenna are interchanged, that is, the state of the initial first antenna is switched from a working state to a non-working state, and the state of the first candidate first antenna is switched from a non-working state to a non-working state; obtain the seventh signal quality data corresponding to the first candidate first antenna after the antenna switching operation and the eighth signal quality data corresponding to the initial second antenna; based on the seventh signal quality data and the eighth signal quality data, determine the first target antenna in the first communication system, and determine the second target antenna in the second communication system.

[0107] Based on the same solution idea, the embodiment of the present application can also solve the interference problem between two communication systems of different standards by directly selecting the antenna in the first antenna system.

[0108] In some embodiments, the method also includes: if the first signal quality data and / or the second signal quality data do not meet the preset signal quality requirements, based on the preset antenna switching strategy, determining a first candidate first antenna from at least one candidate first antenna, and switching the working states of the initial first antenna and the first candidate first antenna, specifically, exchanging the states of the initial first antenna and the first candidate second antenna, that is, switching the state of the initial first antenna from a working state to a non-working state, and switching the state of the first candidate first antenna from a non-working state to a non-working state; obtaining the seventh signal quality data corresponding to the first candidate first antenna after the antenna switching operation and the eighth signal quality data corresponding to the initial second antenna; based on the seventh signal quality data and the eighth signal quality data, determining the first target antenna in the first communication system, and determining the second target antenna in the second communication system.

[0109] In some embodiments, based on the seventh signal quality data and the eighth signal quality data, the steps of determining the first target antenna in the first communication system and determining the second target antenna in the second communication system include: determining whether the seventh signal quality data and the eighth signal quality data both meet the preset signal quality requirements; if the seventh signal quality data and the eighth signal quality data both meet the preset signal quality requirements, determining the first candidate first antenna as the first target antenna and the initial second antenna as the second target antenna.

[0110] In the embodiment of the present application, signal analysis is performed on the first signal and the second signal transmitted by the first communication system and the second communication system of two different communication standards, and based on the first signal quality data and the second signal quality data obtained by the analysis, the first target antenna and the second target antenna that can optimize the coexistence interference between the first communication system and the second communication system are determined in the first communication system and the second communication system respectively, and the first target antenna and the second target antenna are selected for communication, thereby reducing the mutual interference between the two different communication standards, so that the communication quality of the different standards can be guaranteed, thereby achieving the beneficial effect of the two communication systems working concurrently and not interfering with each other, and ensuring the normal use of the terminal product.
