The specific structure of the RF circuit in the method for controlling the RF circuit according to the disclosure may refer to a structural diagram of the terminal device in any embodiment of the present disclosure, which is not limited in the disclosure.
Optionally, when the RF circuit works in the TDD frequency band within the FR1, since the sending circuit and the reflection circuit in the RF circuit in the terminal device respectively adopt different antennas, it may be determined that the sending circuit is connected to the main antenna to send the detection signal, and the reflection circuit is connected to the receiving diversity antenna to receive the detection feedback signal.
It may be understood that, since the sending circuit and the reflection circuit in the RF circuit are respectively connected to different antennas, when the RF circuit works in the TDD frequency band within the FR1, there may be no signal interference between the sending circuit and the reflection circuit. Therefore, the detection function may be achieved by directly multiplexing the sending circuit and the reflection circuit in the RF circuit. That is, the reflection circuit in the embodiments of the disclosure is a multiplexed receiving circuit in the RF circuit.
For example, in the diagram as illustrated in
In the embodiments of the disclosure, if the sending circuit and the reflection circuit in the RF circuit in the terminal device adopt different antennas, when the terminal device works in the detection mode and the RF circuit works in the TDD frequency band within the FR1, the sending circuit in the RF circuit may be controlled to connect with the main antenna to send the detection signal, and the reflection circuit in the RF circuit may be controlled to connect with the receiving diversity antenna to receive the detection feedback signal.

For example, in the diagram as illustrated in
In embodiments of the disclosure, if the terminal device includes a plurality of antenna arrays, when the terminal device works in the detection mode and the RF circuit works in the TDD frequency band within the FR2, the terminal device may control the sending circuit in the RF circuit to connect with one antenna array, and control the reflection circuit to connect with the other antenna array. Therefore, the detection function may be achieved by multiplexing the RF circuit in the terminal device, which further enriches the functions of the terminal device without increasing a hardware burden of the terminal device.

When the terminal device works in the non-detection mode, the sending circuit may be connected to the main antenna to send an RF signal. When the RF signal needs to be received, the first connection end (1) of the first switch unit (53) may be connected with the second connection end (2) to receive the RF signal.
In the embodiments of the disclosure, if the sending circuit and the reflection circuit in the terminal device are respectively connected to different antennas, when the terminal device works in the detection mode and the RF circuit works in the FDD frequency band within the FR1, the reflection circuit may be controlled to connect with the receiving diversity antenna.
