Wherein the first radio frequency signal may be a short range wireless communication signal, for example, may be a Bluetooth (BT) signal; for example, the introduction may be a WIFI signal. It is understood that the first radio frequency signal is not limited to BT signal, WIFI signal.
The first processing module 10, the second processing module 20, and the third processing module 30 are respectively configured to support transmission of the first radio frequency signal, and specifically, the first processing module 10, the second processing module 20, and the third processing module 30 may respectively support corresponding transmission of the first radio frequency signal from the radio frequency transceiver 40 to the first antenna ANT0, the second antenna ANT1, and the third antenna ANT2, and may also respectively support transmission of the first radio frequency signal from the first antenna ANT0, the second antenna ANT1, and the third antenna ANT2 to the radio frequency transceiver 40.

Optionally, when the first processing module 10, the second processing module 20, and the third processing module 30 can process the first rf signal and then transmit the processed first rf signal, the first processing module 10, the second processing module 20, and the third processing module 30 can be Front-end module (FEM) chips, respectively, which can support amplifying the rf signal to increase the transmission distance.
The rf transceiver 40 is configured with a first transceiver port BT0 TRX and a second transceiver port BT1 TRX that support the transceiver of the first rf signal, where the first transceiver port BT0 TRX and the second transceiver port BT1 TRX are independent and do not interfere with each other.

Wherein the target antenna group includes the second antenna ANT1, further includes any one of the first antenna ANT0 and the third antenna ANT2, based on the first transmit-receive port BT0 TRX and the second transmit-receive port BT1 TRX, on the one hand, the radio frequency transceiver 40 may switch between the first antenna ANT0 and the third antenna ANT2 to achieve switching of the target antenna group, for example, from the target antenna group including the first antenna ANT0 and the second antenna ANT1 to the target antenna group including the second antenna ANT1 and the third antenna ANT 2; on the other hand, the rf transceiver 40 may support the transmission and reception of the first rf signal by any one antenna in the target antenna group and support the reception of the first rf signal by another antenna in the target antenna group, so as to implement the function switching of the transmitting antenna and the receiving antenna in the target antenna group, for example, taking the target antenna group being switched to include the first antenna ANT0 and the second antenna ANT1 as an example, the rf transceiver 40 may implement the switching of the transmitting antenna from the first antenna ANT0 to the second antenna ANT1 and the receiving antenna from the second antenna ANT1 to the first antenna ANT0, and may also implement the switching of the transmitting antenna from the second antenna ANT1 to the first antenna ANT0 and the receiving antenna from the first antenna ANT0 to the second antenna ANT1.

For example, the preset condition includes that the number of the data packets accumulated by the first antenna or the third antenna in the target antenna group before the antenna group is switched is smaller than a receiving threshold; or the accumulated operating time before the antenna group is switched is less than the time threshold. When the preset condition is met, only the switching of the receiving antenna and the transmitting antenna in the current target antenna group is needed, and the target antenna group is not needed to be switched.
The first signal quality information refers to information in the current period, which may represent signal quality during transceiving or receiving of each antenna of the target antenna group, and may include original and processed information associated with radio performance metrics of the received radio frequency signal, such as signal strength, received Power, reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP), signal received strength (RECEIVED SIGNAL STRENGTH Indicator, RSSI), signal-to-noise ratio (Signal to Noise Ratio, SNR), rank (Rank) of the MIMO channel matrix, carrier-to-interference-and-noise ratio (Carrier to Interference plus Noise Ratio, RS-CINR), frame error rate, bit error rate, reference signal received quality (REFERENCE SIGNAL reception quality, RSRQ), and the like.

For example, the number of data packets accumulated by the first antenna or the third antenna in the current target antenna group before the antenna group is switched is greater than or equal to the reception threshold; or accumulating the operational time period before the antenna group switch to be greater than or equal to the time period threshold. When the preset condition is not satisfied, the target antenna group needs to be switched.
The second signal quality information refers to information that can characterize signal quality in the receiving and transmitting process of each antenna of the target antenna group after switching in the current period, and description of the signal quality information can refer to the above embodiment.
The control module is used for acquiring the first signal quality information of each antenna in the target antenna group before switching and the second signal quality information of each antenna in the target antenna group after switching under the condition that the data receiving information does not meet the preset condition, so that an antenna with better signal quality in the three antennas can be acquired as a target antenna for supporting the receiving and transmitting of the first radio frequency signal in the next period according to the first signal quality information and the second signal quality information, the switching of the receiving and transmitting antennas and the receiving antennas is realized, the radio frequency system can exert better performance, and the signal transmission quality is improved. Taking signal quality information as signal receiving intensity, and taking the example that the target antenna group is switched from the first antenna, the second antenna to the second antenna and the third antenna, the third antenna also receives the data packet after switching, so that the signal receiving intensity of the first antenna before switching, the signal receiving intensity of the third antenna after switching and the signal receiving intensity of the second antenna before/after switching can be compared, and the target antenna is judged in the three antennas. It can be understood that if the performance of the second antenna is better than the performance of the first antenna after the target antenna group is switched, the signal receiving intensities of the third antenna and the second antenna can be directly compared after the switching, and the target antenna can be determined according to the signal receiving intensities of the third antenna and the second antenna

When the difference value between the second signal receiving intensity and the first signal receiving intensity is greater than or equal to a preset threshold value, the second target antenna is better in performance than the first target antenna, so that the transceiver antenna can be configured as the second target antenna by the first target antenna, and the transceiver performance is improved; in contrast, in the case where the difference between the second signal reception intensity and the first signal reception intensity is smaller than the preset threshold, it is indicated that the first target antenna is better in performance than the second target antenna, so that the transceiver antenna can be kept as the first target antenna to improve the transceiver performance.

Under the condition that the data receiving information does not meet the preset condition, the first signal quality information of each antenna in the target antenna group before switching and the second signal quality information of each antenna in the target antenna group after switching are obtained, so that the antenna with better signal quality in the three antennas can be obtained as the target antenna for supporting the receiving and transmitting of the first radio frequency signal in the next period according to the first signal quality information and the second signal quality information, the switching of the receiving and transmitting antennas and the receiving antennas is realized, the radio frequency system can exert better performance, and the signal transmission quality is improved. Taking signal quality information as signal receiving intensity, and taking the example that the target antenna group is switched from the first antenna, the second antenna to the second antenna and the third antenna, the third antenna also receives the data packet after switching, so that the signal receiving intensity of the first antenna before switching, the signal receiving intensity of the third antenna after switching and the signal receiving intensity of the second antenna before/after switching can be compared, and the target antenna is judged in the three antennas. It can be understood that if the performance of the second antenna is better than that of the first antenna after the target antenna group is switched, the signal receiving intensities of the third antenna and the second antenna may be directly compared after the switching, and the target antenna may be determined according to the signal receiving intensities of the third antenna and the second antenna.

It can be understood that when the target antenna group is switched, the corresponding target channel and the corresponding processing module are also switched at the same time, so that the first target antenna and the second target antenna of the switched target antenna group can respectively support the receiving and transmitting of the first radio frequency signal.
It will be appreciated that in the above embodiment, the target antenna may be determined by the signal receiving strength, and in other embodiments, the determination may be performed in combination with various information, for example, when the target antenna is determined between the first antenna and the second antenna, or when the target antenna is determined between the second antenna and the third antenna, the determination may be performed by two indexes of the signal receiving strength and the signal to noise ratio; when the target antenna group is switched and the switching of the first antenna and the third antenna is involved, the judgment can be performed by three indexes of signal receiving intensity, signal to noise ratio and retransmission rate. Of course, the determination may be made in combination with other information, and is not illustrated herein.
Referring to fig. 10 (where "T" represents transmission and "R" represents reception in fig. 10), the above communication control method is further explained by taking the first radio frequency signal as the BT signal as an example:
In this embodiment, the rf transceiver supports two BT signal reception and one transmission, and uses the first transceiver port BT 0-the first antenna ANT0 to transmit and receive signals (e.g., BT0-ANT0 in fig. 10) by default, that is, uses the first antenna ANT0 as the target antenna, and then uses the second transceiver port BT 1-the second antenna ANT1 to receive signals in the same RX window without transmitting signals.
Step (1), judging before the target antenna group is not switched:
When the number of data packets transmitted and received at the first antenna ANT0 reaches the threshold th_packet1, the RSSI of the received packet at the first antenna ANT0 is averaged to obtain RSSI 0_0_ave (please refer to fig. 10 in addition, which can be understood as the RSSI average value of the data packet of the 0 TH set received by the first antenna ANT 0), the RSSI of the received packet at the second antenna ANT1 is averaged to obtain RSSI 1_0_ave (which can be understood as the RSSI average value of the data packet of the 0 TH set received by the second antenna ANT 1), and the RSSI 0_0_ave and the RSSI 1_0_ave are compared.
When RSSI 1_0_ave < RSSI 0_0_ave+th1 (corresponding to condition ① in the figure), it indicates that the performance of the first antenna ANT0 is better than that of the second antenna ANT1, and the first antenna ANT0 is configured as the target antenna; when the RSS1_1_ave > RSS0_1_ave+Th1 (corresponding to condition ② in the figure) and the RSS1_2_ave > RSS0_2_ave+Th1 (corresponding to condition ③ in the figure), it is indicated that the performance of the second antenna ANT1 is better than that of the first antenna ANT0 at this time, the second antenna ANT1 is configured as the target antenna. The TH1 may be compared with the difference between the signal receiving intensities of the two antennas, so as to determine the threshold values of the first antenna ANT0 and the second antenna ANT1, and the TH1 may be specifically adjusted according to the actual situation.
Step (2), judging the switching process of the target antenna group:
When the data packet received by the first antenna ANT0 reaches the reception threshold or reaches the periodic time point, the switching module in the above embodiment is controlled to disconnect the path between the first transceiving port and the first processing module 10 and to conduct the path between the first transceiving port and the third processing module 30, so as to switch the first antenna ANT0 to the third antenna ANT2.
When switching to the third antenna ANT2, RSSI 2_n_ave (which may be understood as an average value of the RSSI of the nth set of data packets received by the third antenna ANT 2), RSS 1_n_ave, RSSI 0_n-1_ave are compared:
If RSSI 2_n_ave is optimal, configuring a third antenna ANT2 as a target antenna; if RSS1_ [ n ] _ ave is optimal, selecting a second antenna ANT1 to transmit a data packet; if RSSI 0_n-1_ave is optimal, comparing the sizes of RSSI 0_n-1_ave and RSSI 1_n-1_ave, and configuring a target antenna according to the comparison result. For example, in fig. 10, RSS 1_3_ave (corresponding to condition ④ in the figure) is the optimal example, and the target antenna is configured as the second antenna ANT1.
Step (3), judging after the target antenna group is switched:
