The near field communication module includes, but is not limited to, a Bluetooth (BT) communication module, a WIFI communication module, a near field wireless communication (Near Field Communication, NFC) communication module, and the like. Alternatively, the first communication module 100 and the second communication module 200 may be integrated in the same radio frequency chip, thereby improving the integration level of the radio frequency system. The integrated radio frequency chip may be configured with a plurality of ports to implement a signal transmission function. The switch module 300 includes two first ends and a plurality of second ends, the two first ends of the switch module 300 are respectively connected with the first communication module 100 and the second communication module 200 in a one-to-one correspondence manner, and the plurality of second ends of the switch module 300 are respectively connected with a plurality of antennas in a one-to-one correspondence manner. In the embodiment shown in fig. 1, the radio frequency system includes two antennas, and the switch module includes two second ends, so that the two second ends of the switch module 300 are respectively connected to the two antennas in a one-to-one correspondence. The switch module 300 is configured to selectively conduct a signal transmission path between the first communication module 100 and any one of the antennas, and to selectively conduct a signal transmission path between the second communication module 200 and any one of the antennas.
Further, the switch module 300 may respectively turn on the first communication module 100 and the second communication module 200 to different antennas at the same time. By configuring different antennas for the first communication module 100 and the second communication module 200, interference between radio frequency signals of different systems can be further suppressed based on the inherent isolation between the different antennas, thereby improving the communication quality of the first communication module 100 and the second communication module 200 in the coexistence scene.
In this embodiment, by setting the switch module 300, the radio frequency system can connect the first communication module 100 and the second communication module 200 to appropriate antennas according to specific communication requirements, so as to adjust the signal transmission path, thereby improving the communication flexibility of the radio frequency system when performing near field communication.
Fig. 2 is a second schematic structural diagram of an rf system according to an embodiment, referring to fig. 2, in one embodiment, the multiple antennas of the rf system include a first antenna ANT0 and a second antenna ANT1, the second communication module 200 includes a first communication unit 210 and a second communication unit 220, the first communication unit 210 and the second communication unit 220 are used for supporting the transceiving of near-field communication signals with the same communication system and different operating frequencies, and the rf system further includes a first filter 410 and a first combiner 510. The first filter 410 is connected to one first end of the first communication unit 210 and one first end of the switch module 300, respectively. Two first ends of the first combiner 510 are respectively connected to one second end of the switch module 300 and the second communication unit 220 in a one-to-one correspondence, and the second end of the first combiner 510 is connected to the second antenna ANT 1. Wherein another first end of the switch module 300 is connected to the first communication module 100, and another second end of the switch module 300 is connected to the first antenna ANT 0.
Specifically, if the second communication module 200 is a WIFI communication module, the operating frequency of the first communication unit 210 may be 2.4G, and the operating frequency of the second communication unit 220 may be 5G. In the present embodiment, by setting a plurality of operating frequencies for the second communication module 200, a more flexible communication function can be realized. By arranging the first filter 410 on the signal transmission path, noise signals can be filtered, so that the receiving and transmitting quality of the signals is improved. Moreover, by providing the first combiner 510, the same antenna can be used to transmit and receive the near field communication signals with the same communication system and different operating frequencies, thereby reducing the number of antennas to be set.
Fig. 3 is a third schematic structural diagram of an rf system according to an embodiment, referring to fig. 3, in one embodiment, the second communication module 200 includes two first communication units 210 and two second communication units 220, and the operating frequency of the first communication module 100 is the same as that of the first communication units 210. Specifically, the operating frequency of the first communication module 100 and the operating frequency of the first communication unit 210 may be both 2.4G. The rf system further includes a second filter 420 and a second combiner 520, one first end of the switch module 300 is connected to one of the first communication units 210 through the first filter 410, the other first end of the switch module 300 is connected to the other of the first communication units 210 and the first communication module 100 through the second filter 420, two first ends of the second combiner 520 are respectively connected to one second end of the switch module 300 and one of the second communication units 220, and a second end of the second combiner 520 is connected to the first antenna ANT 0. In this embodiment, since the operating frequency of the first communication module 100 is the same as the operating frequency of the first communication unit 210, the first communication module may be filtered by the same filter and transmitted to the same port of the rf chip, so as to reduce the number of filters that need to be set. In addition, by setting the two first communication units 210 and the two second communication units 220, when the working mode of time division multiplexing is adopted, MIMO receiving can be selected for the radio frequency signal of 2.4G according to the actual receiving and transmitting requirement, and MIMO receiving can also be selected for the radio frequency signal of 5G, so as to further improve the receiving speed of the radio frequency signal.
In one embodiment, fig. 4 is a schematic structural diagram of a radio frequency system according to one embodiment, referring to fig. 4, the radio frequency system further includes a matching resistor, and multiple antennas of the radio frequency system further include a third antenna ANT2. The switch module 300 further includes a first end and a second end that are newly added, i.e., the switch module 300 includes three first ends and three second ends in total. The newly added first end of the switch module 300 is connected to the matching resistor. For example, when the radio frequency system includes the first filter 410 and the second filter 420, three first ends of the switch module 300 are respectively connected to the first filter 410, the second filter 420 and the matching resistor in a one-to-one correspondence. A second end of the switch module 300 is connected to the third antenna ANT2.

In this embodiment, by setting three antennas, more flexible antenna selection and switching can be achieved, and communication quality can be improved. Moreover, based on the above structure, the switch module 300 can switch the antennas that are not switched on to the first communication module 100 and the second communication module 200 to the matching resistor by switching, so as to avoid the mismatch problem, thereby avoiding the antenna damage and other problems caused by the mismatch, and further improving the reliability and the service life of the radio frequency system.
The embodiment of the application also provides a communication control method for controlling the working modes of the first communication module and the second communication module in the radio frequency system. The radio frequency system may be any of the radio frequency systems in the foregoing embodiments. Fig. 5 is a flowchart of a communication control method according to an embodiment, and referring to fig. 5, the communication control method includes steps 502 to 506.
Step 502, obtaining the switch states of the first communication module and the second communication module respectively.
The switch state refers to a state of whether a first communication module and a second communication module of the radio frequency system are turned on or not. Specifically, through a control button in a UI interface of the radio frequency system, a user can control on-off states of the first communication module and the second communication module, respectively. It can be understood that when the communication module is turned on, the radio frequency system can support the communication function of the corresponding system, but whether the communication module actually performs communication is determined by an application program running in real time by the communication device. Optionally, after the communication device completes the startup initialization, the switch states of the first communication module and the second communication module may be respectively obtained by monitoring a system broadcast information mode carrying the switch states.
And step 504, when the first communication module and the second communication module are both started, acquiring a communication application scene of the radio frequency system.
When the first communication module and the second communication module are both opened, the radio frequency system can currently support coexistence of the two communication modules. If neither the first communication module nor the second communication module is turned on, or only one of the first communication module and the second communication module is turned on, the interference problem in the coexistence scene is not necessarily existed between the two communication modules. Accordingly, there is no need to employ frequency division multiplexing (Frequency Division Duplexing, FDD) or time division multiplexing (Time Division Duplexing, FDD) modes of operation for interference suppression. Communication application scenes include, but are not limited to, information chat scenes, audio chat scenes, video chat scenes, game scenes, listening to songs, and the like.
And step 506, when the communication application scene is a preset scene, controlling the first communication module and the second communication module to communicate in a frequency division multiplexing working mode.
Specifically, the working mechanism of the frequency division multiplexing working mode is that two communication modules respectively work in different frequency bands or channels, and a protection interval is reserved. Illustratively, the first communication module operates on a 2442MHz channel with a bandwidth of 20MHz and the second communication module operates on a 2442±x MHz channel with a bandwidth of 1MHz, the x value being related to antenna isolation.
In this embodiment, by acquiring the switch states of the first communication module and the second communication module, it can be determined whether a communication mode in which two communication systems coexist is currently supported. And when the coexisting communication mode is supported, comprehensively judging the communication application scene, so that the first communication module and the second communication module can be accurately controlled to adopt a frequency division multiplexing working mode, and further the communication quality of the radio frequency system is improved.
Fig. 6 is a sub-flowchart of an embodiment for obtaining a communication application scenario of the radio frequency system, referring to fig. 6, in one embodiment, the steps include steps 602 to 604.
And step 602, acquiring environment information of the radio frequency system and running information of an application program.
Wherein the environmental information includes at least one of sensing information and on-off screen information of each sensor. Specifically, the sensing information of the sensor may further include gyroscope information, attitude sensor information, optical sensor information, and the like. After determining that both communication modules are started, the running information and the environment information of the application program of the radio frequency system can be periodically acquired at a preset frequency to acquire the real-time information of the radio frequency system, so that the working mode is switched in time. The running information of the application program refers to the application program running on the current upper layer of the radio frequency system. Moreover, part of environment information to be acquired can be determined according to the running information of the application program, so that the acquisition speed and the analysis speed of the environment information are improved.
And step 604, determining a communication application scene of the radio frequency system according to the running information of the application program and the environment information.
Specifically, the communication application scene is determined according to the running information of the application program and the environment information. For example, if the running information of the application indicates that the application running on the upper layer is a game program, the environment information indicates that the holding direction of the communication device is horizontal and the top antenna is blocked, it may be determined that the communication application scenario of the radio frequency system is a horizontal screen holding game scenario. In another example, if the running information of the application indicates that the application running on the upper layer is a music program, the environment information indicates that the communication device is in a screen-off state and the side antenna is blocked, it may be determined that the communication application scene of the radio frequency system is a pocket song listening scene. It will be appreciated that the above two examples are for illustration only and are not intended to limit the scope of the present embodiments.
In this embodiment, by acquiring the running information of the application program, the application program running on the current upper layer can be learned, and the communication application scenario can be more accurately determined in combination with the information such as the environment state when the radio frequency system corresponding to the environment information is used.
In one embodiment, the radio frequency system includes multiple antennas, fig. 7 is a sub-flowchart of an embodiment of controlling the first communication module and the second communication module to communicate in a frequency division multiplexing operation mode, and referring to fig. 7, in this embodiment, the steps include steps 702 to 704.
Step 702, determining a first target antenna corresponding to the first communication module and a second target antenna corresponding to the second communication module according to the communication quality of the channels corresponding to the antennas.
Wherein the first target antenna and the second target antenna are different antennas. Specifically, the antennas may be allocated according to the communication requirements of the first communication module and the second communication module, so as to ensure that both the first communication module and the second communication module can communicate with better quality.
Step 704, the first communication module is conducted to the first target antenna, and the second communication module is conducted to the second target antenna, so as to control the first communication module and the second communication module to communicate in a frequency division multiplexing working mode.
In this embodiment, different antennas are configured for the first communication module and the second communication module, so that on the basis of different operating frequencies, interference between radio frequency signals of different systems can be further suppressed based on inherent isolation between the different antennas, thereby improving communication quality of the first communication module and the second communication module in a coexistence scene. In addition, by selecting the antenna based on the communication quality, each communication module can be flexibly switched to be conducted to the antenna with better communication quality. Based on the switching mode, the problem of blocking caused by the reason that the attenuation of signals is extremely increased and the like due to the fact that the impedance deviation of an antenna is increased and the energy radiated by signals through the antenna is greatly reduced can be effectively avoided.
In one embodiment, FIG. 8 is one of the sub-flowcharts of step 702 of one embodiment, referring to FIG. 8, which includes steps 802 through 806.
Step 802, determining a first candidate antenna corresponding to the first communication module according to the signal quality when the first communication module is conducted to each antenna.
Step 804, determining a second candidate antenna corresponding to the second communication module according to the signal quality when the second communication module is conducted to each antenna.
The first communication module may be respectively conducted to each antenna to respectively obtain radio frequency performance parameters of each channel, so as to determine signal quality. Radio frequency performance parameters include, but are not limited to, received Signal strength indication (Received Signal Strength Indicator, RSSI), packet loss rate, signal-to-Noise Ratio (SNR), etc. Specifically, the first candidate antenna is an antenna with the best signal quality of the channel formed when the first candidate antenna is conducted to the first communication module, and the second candidate antenna is an antenna with the best signal quality of the channel formed when the second candidate antenna is conducted to the second communication module.
Step 806, when the first candidate antenna and the second candidate antenna are different antennas, using the first candidate antenna as the first target antenna and using the second candidate antenna as the second target antenna.
Specifically, when the first candidate antenna and the second candidate antenna are different antennas, it may be considered that the first communication module and the second communication module do not have the problem of collision of occupation of the antennas. Therefore, in this embodiment, when there is no collision of occupation of the antennas, according to the detection results of the signal quality in step 802 and step 804, the allocation of the antennas may be directly performed, so as to ensure that both the first communication module and the second communication module can perform communication with the best quality.
In one embodiment, fig. 9 is a second sub-flowchart of step 702 of one embodiment, and referring to fig. 9, the steps include steps 902 to 906 in addition to the steps of the embodiment of fig. 8.
And step 902, when the first candidate antenna and the second candidate antenna are the same antenna, acquiring the module priority corresponding to the current communication application scene.
The module priority refers to communication priority of the first communication module and the second communication module. The communication priority may be determined according to the traffic demand of each communication module, i.e. a communication module with a large traffic demand corresponds to a higher communication priority. Specifically, the processor may store a mapping relationship between a preset scene set and a module priority. In this step, the stored mapping relationship may be directly obtained, so as to determine the module priority corresponding to the current communication application scenario.
And step 904, when the priority of the first communication module is higher than that of the second communication module, using the first candidate antenna as the first target antenna, and using one of the rest antennas as the second target antenna.
Step 906, when the priority of the first communication module is lower than the priority of the second communication module, using the second candidate antenna as the second target antenna, and using one of the remaining antennas as the first target antenna.
Specifically, when the first communication module and the second communication module have antenna occupation conflict, antenna allocation is performed according to the module priority, so that the communication module with higher priority can be ensured to have required communication quality. For example, if the radio frequency system includes two antennas, and the first candidate antenna and the second candidate antenna are the same antenna ANT0, but the priority of the first communication module is lower than that of the second communication module, the antenna ANT0 may be allocated to the second communication module for use, and the antenna ANT1 may be allocated to the second communication module for use. In this embodiment, by the antenna switching manner, efficient allocation of antennas can be achieved, so that communication quality of a relatively important communication module is ensured while antenna collision is avoided.
In one embodiment, the first communication module is a bluetooth communication module, the second communication module is a WIFI communication module, and if the current communication application scene is a video transceiving scene or a horizontal screen hand-held game scene, the priority of the WIFI communication module is higher than that of the bluetooth communication module. The video transceiving scene includes a video call scene, a video live broadcast scene, and the like, which is not limited in this embodiment. It can be understood that the flow demand of the video image is larger, so in this embodiment, the antenna with the best communication quality can be allocated to the WIFI communication module, thereby avoiding the jamming of the video image and improving the use feeling of the user.
In one embodiment, the first communication module is a bluetooth communication module, the second communication module is a WIFI communication module, and if the current communication application scene is a pocket song listening scene, the priority of the bluetooth communication module is higher than that of the WIFI communication module. It can be understood that the requirement of the song listening scene of the pocket for WIFI flow is smaller, however, the pocket can cause serious shielding to the antenna and influence the communication quality of Bluetooth. Therefore, in this embodiment, the antenna with the best communication quality may be allocated to the bluetooth communication module, so as to avoid the jamming of the audio transmission, and promote the use experience of the user.
In one embodiment, the communication control method further includes: and when the communication application scene is not the preset scene, controlling the first communication module and the second communication module to communicate in a time division multiplexing working mode. The working mechanism of the time division multiplexing is that two communication modules respectively transmit and receive signals in different time periods. Specifically, the time period divisions of the two communication modules are distinguished by a protection frame (protection frame). That is, the first communication module transmits and receives signals through the antenna in a part of the time period, and the second communication module transmits and receives signals through the antenna in another part of the time period. In this embodiment, different communication modules can occupy the same antenna in a time-sharing manner by using a time-division multiplexing mode, so as to reduce the number of occupied antennas. Based on the above occupation manner, more flexible communication functions, such as MIMO functions, etc., can be realized based on the idle antennas.
It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in the flowcharts described in the above embodiments may include a plurality of steps or a plurality of stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of the steps or stages is not necessarily performed sequentially, but may be performed alternately or alternately with at least some of the other steps or stages.
