In this embodiment, when one of the second antennas 131 is occupied by SRS transmission, each of the first antennas and the remaining second antennas can be used to transmit and receive 5G radio frequency signals, and each of the second antennas can be used to transmit and receive 4G radio frequency signals. Due to multiplexing of the first antennas, the total number of the antennas is reduced, so that the isolation between the antennas is increased, and the interference is reduced; and the number of antennas for sending the sounding reference signals can be ensured to be unchanged to ensure the throughput of the antennas.

Specifically, the first filter element 171 is disposed on a receiving path between the transceiver module 110 and each first antenna 121, and is marked with BW1, when any first antenna 121 receives a 4G radio frequency signal or a 5G radio frequency signal, the signal is transmitted to the first filter element 171, and the first filter element 171 filters interference signals except the 4G radio frequency signal and the 5G radio frequency signal, and transmits the filtered signal to the transceiver module 110.

The division of each module in the rf circuit is only for illustration, and in other embodiments, the rf circuit may be divided into different modules as needed to complete all or part of the functions of the rf circuit.
For specific limitations of the rf circuit, reference may be made to the following limitations of the antenna control method, which are not described herein again. The modules in the radio frequency circuit can be wholly or partially realized by software, hardware and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
Fig. 7 is a flowchart of an antenna control method in an embodiment, and as shown in fig. 7, an embodiment of the present application provides an antenna control method applied to a radio frequency circuit, where the antenna control method includes: step 702 to step 708.
Specifically, referring to fig. 1, each of the first antennas 121 in the first antenna group 120 can receive or transmit both 4G radio frequency signals, such as B3 frequency band, and 5G radio frequency signals, such as N41/N79 frequency band. It should be noted that the frequency bands are only used for illustration, and the operating frequency band of each first antenna 121 is not limited. Each second antenna 131 in the second antenna group 130 is only used for receiving or transmitting 5G radio frequency signals, such as N41/N79 frequency band. It should be noted that the above frequency bands are only used for illustration, and the operating frequency band of each second antenna 131 is not limited.
Specifically, each of the first antennas 121 and each of the second antennas 131 can be used to transmit SRS to the base station in turn, for example, if 1T4R requires four antennas to transmit SRS in turn, four antennas are arbitrarily selected from the first antenna group 120 and the second antenna group 130 to perform transmission in turn, and if 1T2R requires two antennas to transmit SRS to the base station in turn, two antennas are arbitrarily selected from the first antenna group 120 and the second antenna group 130 to perform transmission in turn. When the transceiver module 110 outputs the SRS, the switch control module 140 selects a preset number of target antenna groups to emit the SRS from the first antenna group 120 and the second antenna group 130, for example, when the SRS is emitted in a 1T4R round, 4 target antenna groups to emit the SRS from the first antenna group 120 and the second antenna group 130 are selected.
And step 706, when the target antenna is the first antenna, controlling the remaining antennas in the first antenna group to transmit and receive the 4G radio frequency signal and the 5G radio frequency signal.
Specifically, when the target antenna for transmitting the SRS is the first antenna 121, it is identified that the first antenna 121 is occupied. When the target antenna for sending the SRS is the first antenna 121, if the transceiver module 110 outputs a 5G radio frequency signal, the switch control module 140 controls the transmission path between the remaining first antenna 121 or second antenna 131 and the transceiver module 110 to be conducted for sending; if the transceiver module 110 outputs a 4G rf signal, the switch control module 140 controls the remaining first antenna 121 to be conducted with the transmission path between the transceiver module 110 for transmission; if the external communication device sends a 5G rf signal to the rf circuit 100, the switch control module 140 controls the remaining first antenna 121 or the remaining second antenna 131 to be conducted with the receiving path between the transceiver module 110 for receiving; if the external communication device sends a 4G rf signal to the rf circuit 100, the switch control module 140 controls the remaining first antenna 121 and the receiving path between the transceiver module 110 to be conducted for receiving.
The above-described antenna control method transceives 4G rf signals and 5G rf signals using the remaining antennas in the first antenna group when the sounding reference signal is transmitted to the base station 20 using any one of the first antennas. Due to multiplexing of the first antennas, the total number of the antennas is reduced, so that the isolation between the antennas is increased, and the interference is reduced; the number of antennas for sending the sounding reference signals can be guaranteed to be unchanged so as to ensure the throughput of the antennas; meanwhile, the radio frequency circuit can transmit and receive 4G radio frequency signals and 5G radio frequency signals by using the corresponding antenna at any time, so that the communication performance of the radio frequency circuit can be ensured.
In one embodiment, as shown in fig. 8, the antenna control method further includes: step 802, when the target antenna is a second antenna, controlling at least one first antenna to transmit and receive 4G radio frequency signals and 5G radio frequency signals, and controlling the remaining first antennas in the first antenna group to transmit and receive 5G radio frequency signals.
Specifically, referring to fig. 1, when the target antenna for transmitting the SRS is the second antenna 131, it is identified that the second antenna 131 is occupied. At this time, if the transceiver module 110 outputs a 5G radio frequency signal, the switch control module 140 controls the first antenna 121 or the transmission paths between the remaining second antennas 131 and the transceiver module 110 to be conducted for transmission; if the transceiver module 110 outputs a 4G radio frequency signal, the switch control module 140 controls the transmission path between the first antenna 121 and the transceiver module 110 to be conducted for transmission; if the external communication device sends a 5G rf signal to the rf circuit 100, the switch control module 140 controls the first antenna 121 or the remaining second antenna 131 to be conducted with the receiving path between the transceiver module 110 for receiving; if the external communication device sends a 4G rf signal to the rf circuit 100, the switch control module 140 controls the conduction of the receiving path between the first antenna 121 and the transceiver module 110 for receiving. In this embodiment, when one of the second antennas 131 is occupied by SRS transmission, each of the first antennas and the remaining second antennas can be used to transmit and receive 5G radio frequency signals, and each of the second antennas can be used to transmit and receive 4G radio frequency signals. Due to multiplexing of the first antennas, the total number of the antennas is reduced, so that the isolation between the antennas is increased, and the interference is reduced; and the number of antennas for sending the sounding reference signals can be ensured to be unchanged to ensure the throughput of the antennas.
In one embodiment, as shown in fig. 8, the antenna control method further includes: step 804, when the transceiver module does not transmit the sounding reference signal, controlling at least one first antenna to transmit and receive the 4G radio frequency signal and the 5G radio frequency signal, and controlling the remaining first antennas in the first antenna group to transmit and receive the 5G radio frequency signal.
Specifically, referring to fig. 1, when the transceiver module 110 does not transmit the sounding reference signal, if the transceiver module 110 outputs a 5G radio frequency signal, the switch control module 140 controls the transmission path between the first antenna 121 or the second antenna 131 and the transceiver module 110 to be conducted for transmission; if the transceiver module 110 outputs a 4G radio frequency signal, the switch control module 140 controls the transmission path between the first antenna 121 and the transceiver module 110 to be conducted for transmission; if the external communication device sends a 5G rf signal to the rf circuit 100, the switch control module 140 controls the conduction of the receiving path between the first antenna 121 or the second antenna 131 and the transceiver module 110 for receiving; if the external communication device sends a 4G rf signal to the rf circuit 100, the switch control module 140 controls the conduction of the receiving path between the first antenna 121 and the transceiver module 110 for receiving. The embodiment reduces the total number of the antennas so as to increase the isolation between the antennas and reduce the interference; and the radio frequency circuit can transmit and receive 4G radio frequency signals and 5G radio frequency signals by using enough antennas at any time, so that the communication performance of the radio frequency circuit can be ensured.
