Embodiments of the present invention relate to the communications field, and more specifically, to an antenna configuration method, a terminal device, and an antenna circuit.
A multiple-input multiple-output (Multiple Input Multiple Output, “MIMO” for short) technology mainly improves data throughput experience of a user by using hardware conditions such as a plurality of antennas (for example, four antennas) and a plurality of radio frequency channels (for example, four receive channels) in combination with a chip baseband algorithm. Performance of the MIMO mainly depends on antenna performance, including antenna efficiency (Antenna Efficiency) of each antenna, an antenna efficiency difference (Antenna Imbalance), an antenna correlation (Envelope Correlation Coefficient, “ECC” for short), and antenna isolation (Antenna Isolation). The antenna performance mainly depends on an antenna space of a mobile phone. However, because the antenna space of the mobile phone is limited, it is very difficult to implement multiple-antenna MIMO of different communications modules on the mobile phone terminal.
Currently, a method for implementing multiple-antenna MIMO of different communications modules mainly includes an antenna frequency division mode and an antenna time division mode. Using an LTE communications module and a wireless fidelity (Wireless Fidelity, “WiFi” for short) communications module as an example, the frequency division mode refers to performing, by using a filter, filtering processing on an LTE signal and a WiFi signal that are received by an antenna, leading the WiFi signal obtained after the filtering into a WiFi radio frequency branch, and leading a signal obtained after the WiFi signal is filtered out into an LTE radio frequency branch. In this solution, the filter adds an additional radio frequency insertion loss to each radio frequency branch, affecting both LTE service quality and WiFi service quality. The time division mode refers to controlling an antenna to switch between the different communications modules by using a single pole, double throw switch. Still using the LTE communications module and the WiFi communications module as an example, the time division mode is controlling the antenna to switch between the LTE communications module and the WiFi communications module by using a single pole, double throw switch. Control logic of the single pole, double throw switch is giving priority to the LTE communications module, and use of the antenna by the WiFi communications module is always in a low priority. To be specific, when an LTE service occurs, the antenna is switched to a cellular network communications chip by using the single pole, double throw switch, and the antenna is occupied by the LTE service. In this case, a WiFi service cannot use the antenna. If a user is using the WIFI service in this case, use experience of the user is severely affected.
This application provides an antenna configuration method, a terminal device, and an antenna circuit.

As shown in
Based on this, an embodiment of the present invention provides an antenna circuit used to configure an antenna, so that a plurality of communications module can share the antenna, and the terminal device can support MIMO transmission supporting a plurality of communications technologies, thereby improving scenario experience of a service user.
Specifically,
Each communications module 203 is connected to the non-movable end of at least two switching modules 202, M is a positive integer greater than or equal to 2, and N is a positive integer greater than or equal to 2.
The switching control module 204 is configured to: when a plurality of communications modules 203 simultaneously work, determine communication statuses of the plurality of communications modules 203, determine an antenna use priority of each communications module 203 based on the communication statuses of the plurality of communications modules 203, and configure an antenna for each communications module 203 from the M antennas 201 based on the antenna use priority of the communications module 203 by controlling the switching module 202 connected to the communications module 203.
It may be understood that, the switching module 202 is configured to control the antenna connected to the movable end in the switching module 202 to switch between the communications modules 203 connected to the non-movable ends in the switching module 202.
Optionally, in an example, the N communications modules include a communications module supporting a cellular communications technology and a communications module supporting a near field communications technology.

Optionally, in an example, the communications module supporting the cellular communications technology is an LTE communications module, and the communications module supporting the near field communications technology is a WiFi communications module.
In the foregoing embodiment, the switching module may be a single-pole multi-throw switch, or may be another circuit component that can implement switching between different communications modules. In addition, based on different quantities of communications modules, the switching module correspondingly changes. For example, when the terminal device includes three communications modules, one antenna may be electrically connected to the three communications modules by using a single-pole three-throw switch. A specific type of the switching module is not limited in this application.
An antenna configuration method according to an embodiment of the present invention is described below in detail by using an example in which a terminal device 100 includes four antennas and the antenna circuit shown in
S110: Determine a communication status of each of a plurality of communications modules in a terminal device.
Optionally, the communication status of the communications module includes one or more of the following aspects: (1) A signal status of a wireless communications network corresponding to the communications module. For example, weak receiving, weak transmitting, strong receiving, or strong transmitting. Without loss of generality, the signal status of the wireless communications network may be indicated by using the following signal parameters: a received signal strength indicator (Received Signal Strength Indicator, “RSSI” for short), a received signal code power (Received Signal Code Power, “RSCP” for short), a reference signal received power (Reference Signal Receiving Power, “RSRP” for short), a signal to interference plus noise ratio (Signal to Interference Plus Noise Ratio, “SINR” for short), or a block error rate (Block Error Ratio, “BLEW” for short). (2) A service status of the communications module, for example, a data service, a voice service, or an idle state. (3) A data type, such as a streaming (Streaming) type or a browsing (Browsing) type, of a data service performed by the communications module.
Specifically, when the LTE communications module 102 and the WiFi communications module 103 in the terminal device simultaneously work, the LTE communications module 102 may report a signal status and a service status to the processor 109 by directly using an access transfer (Access Transfer, “AT” for short) channel, and the WiFi communications module 103 may report a signal status and a service status to the processor 109 by directly using a Peripheral Component Interconnect Express (Peripheral Component Interconnect Express, “PCIe” for short) channel. Alternatively, the processor 109 sends, to the LTE communications module 102 by using the AT channel, a triggering signal that triggers the LTE communications module 102 to report a signal status and a service status, and then the LTE communications module 102 reports the signal status and the service status to the processor 109 by using the AT channel. The processor 109 sends, to the WiFi communications module 103 by using the PCIe channel, a triggering signal that triggers the WiFi communications module 103 to report a signal status and a service status, and then the WiFi communications module 103 reports the service status and the service status to the processor 109 by using the PCIe channel. The processor 109 may directly obtain a data type of a data service performed by the LTE communications module 102 or the WiFi communications module 103 from a framework (Framework) layer of an operating system stored in the memory 108.
S120: Determine an antenna use priority of each communications module based on the communication status of the communications module.
Optionally, the processor 109 determines the antenna use priority of each communications module based on the communication status and a preset correspondence. The preset correspondence includes a correspondence between the communication status and the antenna use priority. Alternatively, it may be understood that, the correspondence between the communication status and the antenna use priority is preset in the memory 108. After determining the communication status of each communications module, the processor 109 determines, by querying the preset correspondence, the antenna use priority corresponding to the communications module. For example, the terminal device 100 includes the LTE communications module 102 and the WiFi communications module 103, and the preset correspondence between the communication status and the antenna use priority is: When the communication status is that the LTE communications module 102 performs a voice service, the LTE communications module 102 has a high antenna use priority; and when the WiFi communications module 103 is in an idle state, the WiFi communications module 103 has a low antenna use priority. Therefore, when the processor 109 determines that the communication status of the LTE communications module 103 is performing the voice service, and the communication status of the WiFi communications module is in the idle state, it may be determined that the LTE communications module 102 has the high antenna use priority, and the WiFi communications module 103 has the low antenna use priority.
Optionally, in an example, when the antenna use priority of each communications module is determined, a definition objective of the antenna use priority is giving a relatively high antenna use priority to a communications module corresponding to a service having a relatively high antenna performance requirement, and giving a relatively low antenna use priority to a communications module corresponding to a service having a relatively low antenna performance requirement. Therefore, user experience of a service having a relatively high antenna performance requirement is improved, and normal execution of a service having a relatively low antenna performance requirement is ensured.
For example, a communications module whose communication status is performing a data service or a voice service is defined to have a relatively high antenna use priority, and a communications module whose communication status is idle is defined to have a relatively low antenna use priority. A communications module whose communication status is performing weak receiving/weak transmitting is defined to have a relatively high antenna use priority, and a communications module whose communication status is performing strong receiving/strong transmitting is defined to have a relatively low antenna use priority. A communications module whose communication status is performing a data service, where a data type of the data service is a continuous high speed transmission type such as a streaming type, is defined to have a relatively high antenna use priority. A communications module whose communication status is performing a data service, where a data type of the data service is a discontinuous low speed transmission type such as a browsing type, is defined to have a relatively low antenna use priority.
For example, the antenna use priority may be divided into four levels, which are respectively a highest antenna use priority, a high antenna use priority, a middle antenna use priority, and a low antenna use priority. Specifically, a communications module whose communication status is performing a high speed data transmission service in a signal weak field is defined to have the highest antenna use priority, and the high speed data transmission service may be, for example, a high-definition video or heavy traffic downloading; or a communications module whose communication status is performing a voice service in a signal weak field is defined to have the highest antenna use priority, and the voice service may be, for example, VoLTE, VoWiFi, or a WeChat video; or a communications module whose communication status is using an application (Application, “APP” for short) for which a user is relatively sensitive to frame freezing in a signal weak field is defined to have the highest antenna use priority, and the APP for which a user is relatively sensitive to frame freezing may be, for example, taxi hailing software. A communications module whose communication status is performing a high speed data transmission service in a signal strong field is defined to have the high antenna use priority; or a communications module whose communication status is performing a voice service in a signal strong field is defined to have the high antenna use priority; or a communications module whose communication status is using an APP for which a user is relatively sensitive to frame freezing in a signal strong field is defined to have the high antenna use priority. A communications module whose communication status is performing a low speed data transmission service is defined to have the middle antenna use priority. A communications module whose communication status is an idle state and requiring basic connection maintenance is determined to have the low antenna use priority.
S130: Configure an antenna for each communications module based on the antenna use priority of the communications module.
The processor 109 configures antennas based on antenna use priorities of the LTE communications module 102 and the WiFi communications module 103. The processor 109 notifies the LTE communications module 102 of an antenna configuration result by using the AT channel, and notifies the WiFi communications module 103 of an antenna configuration result by using the PCIe channel.
Then, the LTE communications module 102 and the WiFi communications module 103 perform antenna algorithm adjustment based on a quantity of configured antennas. For example, if a quantity of antennas currently configured for the LTE communications module 102 is 4, and a quantity of antennas configured for the WiFi communications module 103 is 0, the LTE communications module 102 may use a four-antenna algorithm. Assuming that in an antenna reconfiguration process, a quantity of antennas configured for the LTE communications module 102 is 2, and a quantity of antennas configured for the WiFi communications module 103 is 2, the LTE communications module 102 needs to roll back the four-antenna algorithm to a two-antenna algorithm, and the WiFi communications module 103 may use the two-antenna algorithm. For the LTE communications module 102 and the WiFi communications module 103, quantities of configured antennas and executable antenna algorithms are shown in Table 1. In Table 1, m+n indicates that a quantity of antennas configured for the LTE communications module 102 is m, and a quantity of antennas configured for the WiFi communications module 103 is n.
In this embodiment of the present invention, optionally, as shown in
S131: Determine, based on the antenna use priority of each communications module, a quantity of antennas allocated to the communications module.
S132: Configure the antenna for each communications module based on the quantity of antennas allocated to the communications module.
Optionally, in S131, the determining, based on the antenna use priority of each communications module, a quantity of antennas allocated to the communications module is specifically: determining, based on the antenna use priority of each communications module, a maximum quantity of antennas supported by the communications module, and an antenna quantity allocation principle for the communications module, the quantity of antennas allocated to the communications module.
Optionally, in an example, the antenna quantity allocation principle is: A quantity of antennas allocated to a communications module having the highest priority is the maximum quantity of antennas supported by the communications module. If there is one or more remaining antennas, a quantity of antennas allocated to a communications module having the high priority is the maximum quantity of antennas supported by the communications module. The rest can be deduced by analogy until all antennas are allocated or each communications module is allocated the maximum quantity of antennas supported by the communications module.
For example, it is assumed that the LTE communications module 102 has the highest antenna use priority, and the WiFi communications module 103 has the high antenna use priority. A maximum quantity of antennas supported by the LTE communications module 102 is 2, and a maximum quantity of antennas supported by the WiFi communications module 103 is 1. The terminal device 100 includes four antennas 110. Therefore, during antenna quantity allocation, the processor 109 allocates two antennas to the LTE communications module 102. In this case, there are two remaining antennas, so that one antenna is allocated to the WiFi communications module 103. Then, there is one remaining antenna. Both the LTE communications module 102 and the WiFi communications module 103 are allocated the maximum quantity of antennas supported by the LTE communications module 102 and the maximum quantity of antennas supported by the WiFi communications module 103. Therefore, the antenna quantity allocation is complete.
Alternatively, it is assumed that the LTE communications module 102 has the highest antenna use priority, and the WiFi communications module 103 has the high antenna use priority. A maximum quantity of antennas supported by the LTE communications module 102 is 3, and a maximum quantity of antennas supported by the WiFi communications module 103 is 2. The terminal device 100 includes four antennas 110. Therefore, during antenna quantity allocation, the processor 109 allocates three antennas to the LTE communications module 102. In this case, there is one remaining antenna, so that one antenna is allocated to the WiFi communications module 103. Therefore, the antenna quantity allocation is complete.
Optionally, in another example, the antenna quantity allocation principle is shown in
During antenna quantity allocation, the processor 109 first determines, based on the antenna use priority of each communications module, a minimum quantity of antennas allocated to the communications module. Specifically, a correspondence between the antenna use priority and the minimum quantity of antennas may be prestored in the memory 108, so that the processor 109 can determine, based on the antenna use priority of the communications module and the correspondence, the minimum quantity of antennas allocated to the communications module. Then, the processor 109 evenly allocates remaining antennas to each communications module having the priority 1. When a quantity of antennas allocated to the communications module having the priority 1 reaches the maximum quantity of antennas supported by the communications module and there are remaining antennas, the remaining antennas are evenly allocated to each communications module having the priority 2. When a quantity of antennas allocated to the communications module having the priority 2 reaches the maximum quantity of antennas supported by the communications module and there is a remaining antenna, antenna quantity allocation is performed in the foregoing manner until there is no remaining antenna and a quantity of antennas allocated to each communications module reaches the maximum quantity of antennas supported by the communications module. Therefore, the antenna quantity allocation is complete.
For example, it is assumed that a minimum quantity of antennas corresponding to the low antenna use priority is 0, a minimum quantity of antennas corresponding to the middle antenna use priority is 1, and a minimum quantity of antennas corresponding to the highest/high antenna use priority is 2. Table 2 shows a case in which when a maximum quantity of antennas supported by the LTE communications module 102 is 4, a maximum quantity of antennas supported by the WiFi communications module 103 is 2, and the LTE communications module 102 and the WiFi communications module 103 correspond to different antenna use priorities, quantities of antennas that can be respectively allocated to the LTE communications module 102 and the WiFi communications module 103. For example, as shown in Table 2, if the LTE communications module 102 corresponds to the highest antenna use priority, and the WiFi communications module 103 corresponds to the middle antenna use priority, the processor 109 determines that a minimum quantity of antennas allocated to the LTE communications module 102 is 2, a minimum quantity of antennas allocated to the WiFi communications module 103 is 1, and there is one remaining antenna. The antenna use priority of the LTE communications module 102 is higher than the antenna use priority of the WiFi communications module 103. Therefore, the processor 109 allocates the remaining antenna to the LTE communications module 102. Finally, the quantity of antennas that can be allocated to the LTE communications module 102 is 3, and the quantity of antennas that can be allocated to the WiFi communications module 103 is 1.
Table 3 shows a case in which when a maximum quantity of antennas supported by the LTE communications module 102 is 4, a maximum quantity of antennas supported by the WiFi communications module 103 is 4, quantities of antennas that can be respectively allocated to the LTE communications module 102 and the WiFi communications module 103. As shown in Table 3, if the LTE communications module 102 corresponds to the middle antenna use priority, and the WiFi communications module 103 corresponds to the highest antenna use priority, the processor 109 determines that a minimum quantity of antennas allocated to the LTE communications module 102 is 1, a minimum quantity of antennas allocated to the WiFi communications module 103 is 2, and there is one remaining antenna. The antenna use priority of the WiFi communications module 103 is higher than the antenna use priority of the LTE communications module 102. Therefore, the remaining antenna is allocated to the WiFi communications module 103. Finally, the quantity of antennas that can be allocated to the LTE communications module 102 is 1, and the quantity of antennas that can be allocated to the WiFi communications module 103 is 3.
It should be noted that x+y in Table 2 and Table 3 indicates that the quantity of antennas allocated to the LTE communications module 102 is x, and the quantity of antennas allocated to the WiFi communications module 103 is y.
In the foregoing embodiments, if a minimum quantity of antennas corresponding to an antenna use priority of a communications module is greater than a maximum quantity of antennas supported by the communications module, the maximum quantity of antennas supported by the communications module is determined as the minimum quantity of antennas corresponding to the antenna use priority of the communications module.
In this embodiment of the present invention, optionally, before the processor 109 determines the communication status of each of the plurality of communications modules, the processor 109 is further configured to determine a status of the terminal device. When configuring the antenna for each communications module based on the antenna use priority of the communications module, the processor 109 specifically configures the antenna for each communications module based on the antenna use priority of the communications module and the status of the terminal device.
Optionally, the status of the terminal device includes but is not limited to a battery level status of the terminal device and a screen status of the terminal device.
For example, when the processor 109 detects that the touchscreen of the terminal device 100 is enabled, and an application (Application, “APP” for short) currently used by a service user is WeChat (WeChat), to ensure Wechat use experience of the service user, the processor 109 determines that a communications module corresponding to WeChat, for example, the LTE communications module 102, has a relatively high antenna use priority, so that the processor 109 allocates a relatively large quantity of antennas to the LTE communications module 102. Therefore, a communication capability and communication quality of the LTE communications module 102 are ensured, and scenario experience of the service user is improved.
Alternatively, when the processor 109 detects that the battery 111 of the terminal device 100 is in a low battery level state, in a scenario in which the LTE communications module 102 corresponds to the middle antenna use priority, and the WiFi communications module 103 corresponds to the high antenna use priority in Table 3, the processor 109 allocates only one antenna to the LTE communications module 102, and allocates one antenna to the WiFi communications module 103. Therefore, power consumption of the terminal device 100 is reduced.
Further, when configuring the antenna for each communications module, the processor 109 further considers a maximum quantity of antennas supported by a network device corresponding to the communications module. Optionally, the network device may add information indicating the maximum quantity of antennas supported by the network device to a broadcast message, and the terminal device 100 determines, based on the information in the broadcast message, the maximum quantity of antennas supported by the network device. The broadcast message is not limited in this embodiment of the present invention.
Using the case in which the LTE communications module 102 has the highest antenna use priority and the WiFi communications module 103 has the middle antenna use priority in Table 2 as an example, if a maximum quantity of antennas supported by a network device (such as a base station) corresponding to the LTE communications module 102 is 2, when performing antenna configuration, the processor 109 configures two antennas for the LTE communications module 102, and configures one antenna for the WiFi communications module 103.
Further, in this embodiment of the present invention, before the processor 109 performs the antenna configuration, each communications module may be connected to each antenna. Performance evaluation is performed on each antenna by measuring the antenna, and a performance evaluation result is sent to the processor 109. For example, the communications module may evaluate antenna performance by using parameters such as quality of a received signal, a strength of the received signal, a bit error rate of the received signal, and quality of a transmitted signal, sort antenna performance after the evaluation, and report a sorting result to the processor 109. Alternatively, the communications module directly reports a parameter measurement result to the processor 109, and the processor 109 sorts antenna performance. It may be understood that, for different communications modules, antenna performance of different antennas may be different. Therefore, antenna performance may be sorted for each communications module. Then, when configuring the antenna for each communications module, the processor 109 starts the configuration from an antenna with relatively good antenna performance.
Optionally, in an example, the processor 109 specifically configures the antenna for each communications module based on the antenna use priority of the communications module, the quantity of antennas allocated to the communications module, and an antenna performance measurement result and an antenna selection principle for the communications module.
Optionally, in an example, the antenna selection principle is shown in
During antenna selection for each communications module, the processor 109 first selects a minimum preferred quantity of antennas for the communications module in descending order of the antenna use priorities and descending order of antenna performance. Then, an antenna is selected for each communications module having the priority 1 from one or more remaining antennas in an alternate manner. When a quantity of antennas selected for each communications module having the priority 1 reaches the quantity of antennas allocated to the communications module, an antenna is selected for each communications module having the priority 2 from one or more remaining antennas. When a quantity of antennas selected for each communications module having the priority 2 reaches the quantity of antennas allocated to the communications module and there is a remaining antenna, an antenna is selected for the communications module having a relatively low priority (the priority 3 and the priority 4) in the foregoing manner until all antennas are selected.
Optionally, when the minimum preferred quantity of antennas is selected for each communications module, the selection is performed in an order of the antenna use priorities. If a plurality of communications modules has a same priority, an antenna is selected for each communications modules in an alternate selection manner.
For example, it is assumed that the terminal device 100 further includes a Bluetooth communications module, and four antennas 110 (where numbers corresponding to the antennas are 0 to 3) are set in the terminal device 100. The LTE communications module 102 has the high antenna use priority, the WiFi communications module 103 has the middle antenna use priority, and the Bluetooth communications module has the low antenna use priority. Descending order of antenna performance that is determined by the LTE communications module 102 is 0, 1, 2, and 3, descending order of antenna performance that is determined by the WiFi communications module 103 is 1, 2, 3, and 0, and descending order of antenna performance that is determined by the Bluetooth communications module is 2, 3, 0, and 1. The processor 109 determines that a quantity of antennas allocated to the LTE communications module 102 is 2, a quantity of antennas allocated to the WiFi communications module 103 is 1, and a quantity of antennas allocated to the Bluetooth communications module is 1. It is assumed that a minimum preferred quantity of antennas corresponding to the high antenna use priority is 2, a minimum preferred quantity of antennas corresponding to the middle priority is 1, and a minimum preferred quantity of antennas corresponding to the low antenna use priority is 0. In an antenna configuration process, the processor 109 first configures antennas whose numbers are 0 and 1 for the LTE communications module 102, and then configures the antenna whose number is 2 for the WiFi communications module 103. In this case, there is one remaining antenna, a quantity of antennas configured for the LTE communications module 102 has reached the quantity of antennas allocated to the LTE communications module 102, and a quantity of antennas configured for the WiFi communications module 103 has reached the quantity of antennas allocated to the WiFi communications module 103. Therefore, the processor 109 configures the remaining antenna for the Bluetooth communications module, to be specific, configures an antenna whose number is 3 for the Bluetooth communications module.
Each of
Alternatively, it is assumed that the LTE communications module 102 corresponds to the high antenna use priority, and the WiFi communications module 103 corresponds to the high antenna use priority. It can be learned based on the result shown in Table 2 that, a quantity of antennas allocated by the processor 109 to the LTE communications module 102 is 2, and a quantity of antennas allocated by the processor 109 to the WiFi communications module 103 is 2. It is assumed that a minimum preferred quantity of antennas corresponding to the low antenna use priority is 0, a minimum preferred quantity of antennas corresponding to the middle antenna use priority is 1, and a minimum preferred quantity of antennas corresponding to the highest/high antenna use priority is 2. Therefore, the processor 109 selects antennas for the LTE communications module 102 and the WiFi communications module 103 in an alternate selection manner shown in
In this embodiment of the present invention, optionally, antenna allocation is performed in a long time (a second-level to a minute-level)-fixed use scenario, each communications module has the highest priority of use on an antenna allocated to the communications module. On such a basis, the communications modules can share a plurality of antennas (a millisecond-level sharing mechanism). A principle thereof is that when a communications module having the high antenna use priority does not use, within a short time, an antenna configured for the communications module, the antenna configured for the communications module is lent to another communications module having the low antenna use priority for use. Once the communications module having the high antenna use priority needs to use the antenna configured for the communications module, the antenna is immediately returned to the communications module having the high antenna use priority for use. As shown in
In this embodiment of the present invention, optionally, the processor 109 periodically triggers each communications module to report the current communication status or periodically determines the status of the terminal device 100. When the processor 109 determines that a communication status of a communications module changes, or the status of the terminal device 100 changes (for example, the battery level status changes), the processor 109 reconfigures an antenna for each communications module according to the antenna configuration method described in the foregoing embodiments.
In this embodiment of the present invention, optionally, when a status of the touchscreen of the terminal device 100 changes, the touchscreen reports status change information to the processor 109. The processor 109 configures an antenna for each communications module in the terminal device 100 based on the status change information reported by the touchscreen and an APP used by a current service user.
Alternatively, when a communication status of a communications module in the terminal device 100 changes, the communications module reports status change information to the processor 109. The processor 109 determines, based on the status change information reported by the communications module, that the communication status of the communications module changes. In this case, the processor 109 configures an antenna for each communications module in the terminal device 100 according to the antenna configuration method described in the foregoing embodiments.
For example, it is assumed that the terminal device 100 is a mobile phone having four antennas (the mobile phone supports LTE 4 Layer MIMO and WiFi 2 Layer MIMO technologies). A user views a high-definition video on the terminal device 100 by using a WiFi network, and the terminal device 100 is in a WiFi signal weak field area (for example, a WiFi RSSI<−90 dBm), causing a frame freezing phenomenon sometimes occurring in the high-definition video (where the high-definition video frame freezing problem needs to be resolved by using a WiFi multiple-antenna technology). However, when the terminal device 100 is in a signal strong field (for example, an RSRP>−70 dBm) in an LTE network and is in an idle state (for example, periodically listening and paging), a multiple-antenna requirement is relatively low. Based on the foregoing use status, the processor 109 determines that the antenna use priority of the WiFi communications module 103 is the highest antenna use priority, and the antenna use priority of the LTE communications module 102 is the middle antenna use priority. Therefore, as shown in
If at a moment, there is a VoLTE voice call from the LTE network, after the user answers the call, the communication status of the LTE communications module 102 changes, and the LTE communications module 102 reports status change information to the processor 109, so that the processor 109 performs antenna resource reconfiguration. In this case, the processor 109 determines, based on communication statuses of the communications modules, that the antenna use priority of the WiFi communications module 102 is the middle antenna use priority, and the antenna use priority of the LTE communications module 102 is the high antenna use priority. Therefore, as shown in
Then, it is assumed that the user leaves home after disabling WiFi of the terminal device 100 and views a high-definition video by using an LTE network in an outside public place. In this case, both the WiFi communications module 103 and the LTE communications module report status change information to the processor 109, so that the processor 109 performs antenna resource reconfiguration. The processor 109 determines, based on communication statuses of the communications modules in this case, that the WiFi communications module 103 corresponds to the low antenna use priority, and the LTE communications module 102 corresponds to the highest antenna use priority. Therefore, as shown in
