Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present application. Both the first client and the second client are clients, but they are not the same client.

In some related technologies, in order to avoid interference problems when working in the same frequency band at the same time, time division multiplexing technology is used for communication. That is, the radio frequency system performs time-division reception of signals of different communication standards. However, taking Bluetooth (BT) and WIFI as examples, networks of different communication standards will compete for hardware periodically. If the hardware is grabbed by Bluetooth, it will cause the communication between WIFI and router to be interrupted, and vice versa. Relevant improvement technologies can suppress the above contention problem, but the suppression process will have a great impact on the rate of WIFI and Bluetooth, increase the signal delay, and may lead to an increase in the frequency of WIFI and Bluetooth stuttering. However, if blindly using multiple communication technologies to work at the same time, it may cause the two communications to interfere with each other and make it impossible to communicate, resulting in a decrease in communication quality.

The embodiment of the present application provides a communication control method, which can be applied to a radio frequency system, so that the radio frequency system is in a coexistence working mode matching the anti-blocking information and interference information, and improves communication quality.

The first transceiver circuit 110 and the second transceiver circuit 120 are respectively used to support the transceiver processing of short-distance wireless communication signals of different communication systems, so that the radio frequency system supports short-distance wireless communication of multiple different communication systems, such as WIFI communication, Bluetooth communication etc.

Optionally, the first transceiver circuit 110 supports WIFI communication, and the second transceiver circuit 120 supports Bluetooth communication; optionally, the second transceiver circuit 120 supports WIFI communication, and the first transceiver circuit 110 supports Bluetooth communication. Optionally, WIFI communication and Bluetooth communication can be 2.4G Bluetooth communication and 5G WIFI communication, where 2.4G refers to the 2402MHz-2482MHz of the ISM frequency band; 5G refers to the 5170Mhz-5835Mhz of the existing 5G and future WIFI 6E expansion frequency band.

Optionally, the first transceiver circuit 110 and the second transceiver circuit 120 are respectively connected to the same antenna, so that the first transceiver circuit 110 and the second transceiver circuit 120 support the transmission and reception of communication signals through the same antenna; A transceiver circuit 110 and a second transceiver circuit 120 are respectively connected to different antennas (Fig. 1 is taken as an illustration, only for illustration, not limited), so that the first transceiver circuit 110 and the second transceiver circuit 120 are respectively supported by different antennas.

Exemplarily, the processing circuit 130 may include a short-range wireless communication processor (for example, WIFI&BT chip ) and the CPU. Among them, the short-distance wireless communication processor can be used to complete the conversion and inverse conversion process from digital signal to radio frequency signal, including encapsulation and framing of digital signal, conversion of digital-to-analog signal, modulation, up-conversion and other processes, and finally generates the corresponding WIFI signal or Bluetooth signal, or after receiving the signal, send it to the central processing unit through a series of reverse processes.

Fig. 2 is a flowchart of a communication control method in an embodiment. As shown in FIG. 2 , the communication control method includes step 202 to step 204 .

Step 202, when there is interference between the first transceiver circuit and the second transceiver circuit, obtain the anti-blocking information of the first communication signal transmitted by the first transceiver circuit to the second transceiver circuit, and obtain the anti-blocking information of the first communication signal to the first transceiver circuit. Interference information of the received second communication signal.

Wherein, when there is interference between the first transceiver circuit and the second transceiver circuit, the transceiver circuit in the signal transmitting state will interfere with the reception of the signal by the transceiver circuit in the signal receiving state when transmitting a signal, thereby possibly reducing the The reception quality of the transceiver circuit. In this embodiment, the first transceiver circuit is used as the transceiver circuit in the receiving state, and the second transceiver circuit is used as the transceiver circuit in the transmitting state.

Wherein, the interference of the second transceiver circuit in the transmitting state on the first transceiver circuit in the receiving state includes blocking interference and noise interference of the first communication signal transmitted by the second transceiver circuit on the second communication signal received by the first transceiver circuit. Blocking interference refers to the blockage of the first communication signal to the demodulation of the second communication signal by the receiver of the first transceiver circuit; noise interference refers to the interference of the noise generated when the first communication signal is transmitted to the reception of the second communication signal. The noise is an interference signal within the receiving frequency range of the first transceiver circuit, which may lead to deterioration of the signal-to-noise ratio of the first transceiver circuit. Correspondingly, the anti-blocking information refers to information related to the first transceiver circuit's resistance to blocking interference of the first communication signal, and the interference information refers to information related to noise interference of the first communication signal that the first transceiver circuit withstands.

Wherein, optionally, to determine whether there is interference between the first transceiver circuit and the second transceiver circuit, the coexistence interference parameters of each operating frequency of the second transceiver circuit to each operating frequency of the first transceiver circuit can be preset, and then according to The actually measured coexistence interference parameter is compared with the preset coexistence interference parameter to determine whether there is interference between the first transceiver circuit and the second transceiver circuit. It can be understood that in other embodiments, the coexistence interference parameters of each operating frequency of the first transceiver circuit to each operating frequency of the second transceiver circuit can be preset, and then the actual measured coexistence interference parameters are compared with the preset coexistence interference parameters , to determine whether there is interference between the first transceiver circuit and the second transceiver circuit.

Step 204, when the anti-blocking information satisfies the first threshold condition and the interference information satisfies the second threshold condition, control the first transceiving circuit and the second transceiving circuit to work simultaneously in frequency division multiplexing mode.

Wherein, the first threshold condition is a preset condition that the blocking interference is within the tolerable range of the first transceiver circuit. When the anti-blocking information satisfies the first threshold condition, the first transceiver circuit can withstand the blocking interference caused by the current second transceiver circuit. A receiver of the transceiver circuit is capable of demodulating the received second communication signal.

Wherein, the second threshold condition is a preset condition that the noise interference is within the tolerable range of the first transceiver circuit. When the interference information satisfies the second threshold condition, the first transceiver circuit can withstand the noise interference caused by the current second transceiver circuit, and the reception quality in the tolerable range.

When the anti-blocking information satisfies the first threshold condition and the interference information satisfies the second threshold condition, it means that the interference between the first transceiver circuit and the second transceiver circuit of different communication standards is very small, and the first transceiver circuit and the second transceiver circuit Simultaneous communication of the circuits does not affect each other, and can support the simultaneous operation of the first transceiver circuit and the second transceiver circuit of different communication standards, so that the first transceiver circuit and the second transceiver circuit can be controlled to work simultaneously in the frequency division multiplexing working mode.

In the communication control method provided in this embodiment, when there is interference between the first transceiver circuit and the second transceiver circuit, the anti-blocking information of the first communication signal transmitted by the first transceiver circuit to the second transceiver circuit is obtained to obtain the first Interference information of the communication signal on the second communication signal received by the first transceiver circuit; when the anti-blocking information satisfies the first threshold condition and the interference information satisfies the second threshold condition, the first transceiver circuit and the second transceiver circuit are controlled to use frequency division multiplexing Simultaneously work in the working mode, so that the radio frequency system is in the coexistence working mode matching the anti-blocking information and interference information, so as to improve the communication quality.

In some embodiments, as shown in Figure 3, the method also includes:

Step 206, when the anti-blocking information does not meet the first threshold condition and/or the interference information does not meet the second threshold condition, control the first transceiver circuit and the second transceiver circuit to work independently of each other in a time division multiplexing mode.

Wherein, when the anti-blocking information does not meet the first threshold condition, the first transceiver circuit cannot withstand the blocking interference caused by the current second transceiver circuit, and the first communication signal blocks the demodulation of the receiver of the first transceiver circuit. When the interference information does not meet the second threshold condition, the first transceiver circuit cannot bear the current noise interference caused by the second transceiver circuit, and the noise interference will worsen the noise in the receiving frequency band of the first transceiver circuit, resulting in deterioration of the signal-to-noise ratio.

When the anti-blocking information does not meet the first threshold condition and/or the interference information does not meet the second threshold condition, it indicates that the interference between the first transceiver circuit and the second transceiver circuit of different communication standards is relatively large, and the first transceiver circuit Simultaneous communication with the second transceiver circuit will affect each other, and the first transceiver circuit and the second transceiver circuit of different communication standards are not supported to be carried out simultaneously, thereby controlling the first transceiver circuit and the second transceiver circuit to work independently of each other in a time-division multiplexing mode. That is to say, the first transceiver circuit and the second transceiver circuit are controlled to communicate in time intervals, thereby avoiding mutual interference between the first transceiver circuit and the second transceiver circuit, and improving communication quality.

Optionally, the priority of the first threshold condition is higher than that of the second threshold condition, and when the anti-blocking information does not meet the first threshold condition, the first communication signal blocks the demodulation of the receiver of the first transceiver circuit, and the first The receiver of the transceiver circuit cannot demodulate the second communication signal, and it can directly determine that the first transceiver circuit cannot withstand the interference of the second transceiver circuit to control the first transceiver circuit and the second transceiver circuit to work independently of each other in time-division multiplexing mode. It is then determined whether the interference information satisfies the second threshold condition, thereby saving determination time and improving determination efficiency and communication efficiency.

In the communication control method provided in this embodiment, when there is interference between the first transceiver circuit and the second transceiver circuit, the anti-blocking information of the first communication signal transmitted by the first transceiver circuit to the second transceiver circuit is obtained to obtain the first Interference information of the communication signal on the second communication signal received by the first transceiver circuit; when the anti-blocking information does not meet the first threshold condition and/or the interference information does not meet the second threshold condition, control the first transceiver circuit and the second transceiver circuit The time-division multiplexing working mode is adopted to work independently of each other, so that the radio frequency system is in a co-existing working mode matching the anti-blocking information and interference information, and the communication quality is improved.

It should be noted that, in other embodiments, the method may further include: when the anti-blocking information does not meet the first threshold condition and/or the interference information does not meet the second threshold condition, the second transceiver circuit that controls the transmission state reduces the first The transmission power of the communication signal, and the signal reception strength of the first transceiver circuit that controls the receiving state to receive the second communication signal, and re-execute step 202 and other related steps.

In some embodiments, as shown in FIG. 4 , obtaining the anti-blocking information of the first communication signal transmitted by the first transceiver circuit to the second transceiver circuit includes:

Step 302, acquiring an energy value generated when the second transceiver circuit transmits the first communication signal.

Step 304, acquiring a first suppression capability value of the first transceiver circuit for suppressing blocking of the first communication signal.

Step 306, acquiring anti-blocking information according to the energy value and the first suppression capability value.

Wherein, the anti-blocking information includes information related to resisting blocking interference of the first communication signal, for example, information about the magnitude of blocking interference and the ability of the first transceiver circuit to resist blocking interference. In this embodiment, the size of the blocking interference can be fed back through the energy value generated when the second transceiver circuit transmits the first communication signal, that is, the energy value can be used to feed back the size of the blocking interference; the ability of the first transceiver circuit to resist blocking interference The information may include the first suppression capability value of the first transceiver circuit for suppressing the blocking of the first communication signal, specifically, the first suppression capability value of the first transceiver circuit for suppressing the blocking of the main frequency of the first communication signal to the receiver . Optionally, the first transceiver circuit can suppress the blocking of the first communication signal by setting the first filter, so that the first suppression capability value can be the suppression capability value of the first filter to the transmission frequency point of the second transceiver circuit , can also be understood as the filtering capability of the first filter.

When there is interference between the first transceiver circuit and the second transceiver circuit, by obtaining the energy value generated when the second transceiver circuit transmits the first communication signal, the first suppression ability of the first transceiver circuit to suppress the blocking of the first communication signal is obtained. value, and then the anti-blocking information can be obtained according to the energy value and the first suppression capability value to determine the current anti-blocking situation of the first transceiver circuit and determine whether the first transceiver circuit can demodulate the received second communication signal.

Optionally, the anti-blocking information is a difference between the energy value and the first suppression capability value, wherein: the first threshold condition includes that the anti-blocking information is smaller than the first threshold. The difference between the energy value and the first suppression capability value reflects the current blocking interference actually borne by the receiver of the first transceiver circuit. By judging whether the difference satisfies the first threshold condition, it can be judged whether the blocking interference of the second transceiver circuit is within the tolerable range of the first transceiver circuit. In this embodiment, the first threshold condition includes that the anti-blocking information is smaller than the first threshold, and comparing the difference with the first threshold can determine whether the blocking interference is within the tolerable range of the first transceiver circuit.

Optionally, the first transceiver circuit and the second transceiver circuit are respectively connected to the same antenna, the first threshold is the tolerance value of the first transceiver circuit to an interference signal, and the interference signal is the first The noise received by the transceiver circuit; or the first transceiver circuit and the second transceiver circuit are respectively connected to different antennas, and the first threshold is the sum of the tolerance value and the antenna isolation.

Wherein, the interference signal is noise received by the first transceiver circuit when the second transceiver circuit transmits the first communication signal, and the noise falls within the receiving frequency range of the first transceiver circuit. The antenna isolation refers to the isolation between different antennas when the first transceiver circuit and the second transceiver circuit are connected to different antennas, and the isolation can be adjusted by switching the antennas.

When the first transceiver circuit and the second transceiver circuit are respectively connected to the same antenna, the first threshold is the tolerance value of the first transceiver circuit to the interference signal, when the difference between the energy value and the first suppression capability value is less than the tolerance value , to determine that the first transceiver circuit can withstand the blocking interference of the second transceiver circuit; Block interference. The tolerance value can be set according to actual communication service requirements.

When the first transceiver circuit and the second transceiver circuit are respectively connected to different antennas, the first threshold is the sum of the tolerance value of the first transceiver circuit to the interference signal and the antenna isolation, when the energy value and the first suppression capability value are If the difference is less than the sum of the tolerance value and the antenna isolation, it is determined that the first transceiver circuit can withstand the blocking interference of the second transceiver circuit; when the difference between the energy value and the first suppression capability value is greater than or equal to the tolerance value and the antenna The sum of the isolation degrees determines that the first transceiver circuit cannot withstand the blocking interference of the second transceiver circuit.

In some embodiments, as shown in FIG. 5 , acquiring interference information of the first communication signal on the second communication signal received by the first transceiver circuit includes:

Step 402, acquiring noise generated when the second transceiver circuit transmits the first communication signal, where the noise is an interference signal located within a receiving frequency range of the first transceiver circuit.

Step 404, acquiring a second suppression capability value of the second transceiver circuit for suppressing noise received by the first transceiver circuit.

Step 406, acquiring interference information according to the noise and the second suppression capability value.

Wherein, the interference information refers to information related to the first communication signal noise interference suffered by the first transceiver circuit, and the interference information includes, for example, the size of the noise interference falling within the receiving frequency range of the first transceiver circuit when the second transceiver circuit transmits, and the second Information such as the ability of the transceiver circuit to suppress noise received by the first transceiver circuit. In this embodiment, the magnitude of the noise interference is the noise that falls within the receiving frequency range of the first transceiver circuit when the second transceiver circuit transmits, and the magnitude of the noise can be understood as the rise of the interference signal compared to the noise floor in a clean environment; the second The capability information of the second transceiver circuit for suppressing noise received by the first transceiver circuit may include a second suppression capability value of the second transceiver circuit for suppressing noise received by the first transceiver circuit. Optionally, the second transceiver circuit can set the second filter to realize the out-of-band noise generated when it transmits itself, thereby suppressing the noise from being received by the first transceiver circuit and reducing the signal-to-noise ratio of the receiving frequency band of the first transceiver circuit. The second suppression capability value can be understood as the filtering capability of the second filter.

When there is interference between the first transceiver circuit and the second transceiver circuit, by obtaining the noise falling into the receiving frequency band of the first transceiver circuit when the second transceiver circuit transmits the first communication signal, the noise suppressed by the second transceiver circuit is obtained by the first transceiver circuit. The second suppression ability value received by the transceiver circuit can then obtain interference information according to the noise and the second suppression capability value to determine the actual interference suffered by the first transceiver circuit, and then judge the current interference situation of the first transceiver circuit to determine the second Whether the first transceiver circuit can withstand the interference of the second transceiver circuit.

Optionally, the interference information is a difference between a noise parameter value and a second suppression capability value, wherein: the second threshold condition includes that the interference information is greater than or equal to the second threshold. The parameter value of the noise can be understood as a parameter value measuring the size of the noise, and the difference between the parameter value of the noise and the second suppression capability value reflects the actual noise interference situation that the receiver of the first transceiver circuit currently bears. By judging whether the difference satisfies the second threshold condition, it can be judged whether the noise interference of the second transceiver circuit is within the tolerable range of the first transceiver circuit. In this embodiment, the second threshold condition includes that the interference information is smaller than the second threshold, and comparing the difference with the second threshold can determine whether the noise interference is within the tolerable range of the first transceiver circuit.

Optionally, the first transceiver circuit and the second transceiver circuit are respectively connected to the same antenna, and the second threshold is a preset threshold that the first transceiver circuit can withstand interference; or the first transceiver circuit and the second transceiver circuit are respectively connected to different antennas , the second threshold is the sum of the preset threshold and the antenna isolation.

When the first transceiver circuit and the second transceiver circuit are respectively connected to the same antenna, the second threshold is the preset threshold value of the interference that the first transceiver circuit can withstand, when the interference information is the difference between the parameter value of the noise and the second suppression capability value value is less than the preset threshold, it is determined that the first transceiver circuit can withstand the noise interference of the second transceiver circuit; when the interference information is that the difference between the noise parameter value and the second suppression capability value is greater than or equal to the preset threshold, it is determined that the The transceiver circuit cannot withstand noise interference from the second transceiver circuit. The preset threshold can be set according to actual communication service requirements. For example, the preset threshold can be set to 3dB. When the difference between the parameter value of the interference information being noise and the second suppression capability value is less than 3dB, it can be considered that the second A transceiver circuit can withstand noise interference from a second transceiver circuit.

When the first transceiver circuit and the second transceiver circuit are respectively connected to different antennas, the second threshold is the sum of the preset threshold and the antenna isolation, and when the difference between the parameter value of the interference information being noise and the second suppression capability value is less than The sum of the preset threshold and the antenna isolation determines that the first transceiver circuit can withstand the noise interference of the second transceiver circuit; when the interference information is that the difference between the noise parameter value and the second suppression capability value is greater than or equal to the preset threshold The sum of the isolation degree and the antenna determines that the first transceiver circuit cannot withstand the noise interference of the second transceiver circuit.

It can be understood that in other embodiments, the second transceiver circuit may also be used as the transceiver circuit in the receiving state, and the first transceiver circuit may be used as the transceiver circuit in the transmitting state. It can be understood that when the second transceiver circuit is used as the transceiver circuit in the receiving state, and the first transceiver circuit is used as the transceiver circuit in the transmitting state, the relevant steps of the communication control method are only to replace the first transceiver circuit and the second transceiver circuit, specifically The steps and procedures still refer to the relevant descriptions of the above embodiments, and will not be repeated here.
